Technical Field

[0001] The present invention relates to the field of tax declaration, and in particular to a method and system for processing abnormal tax declaration. Background Art

[0002] At present, when enterprises declare taxes and fees, the data involved is particularly wide-ranging. For example, the company's sales data, input data, and financial-related data are required, and the amount of data is large. In addition, different companies have different types of taxes to declare, and each type of tax needs to organize data separately. Therefore, when declaring each type of tax, different abnormal information often appears, resulting in the inability to declare smoothly. Therefore, for different abnormal information, the declarant may need to check the accuracy of different data, and there is a correlation between different data, which makes verification difficult. If you want to solve such problems, you often need to consult the tax bureau or tax teachers and other methods to consult and solve them, which increases the workload of the enterprise and greatly reduces the speed of the enterprise's declaration. Moreover, the tax bureau's verification pop-up box is constantly changing: increasing or decreasing, which further increases the workload of the enterprise and reduces the speed of declaration. Summary of the invention

[0026] like Figure 1 As shown, in combination with an embodiment of the present invention, a method for processing tax declaration anomalies is provided, comprising:

[0027] S101: When the enterprise declares any tax, the pop-up box that appears is collected in the form of an image to obtain the corresponding pop-up box image;

[0028] S102: Identify data in the pop-up picture, and extract valid information carried in the data;

[0029] S103: inputting the valid information into a trained bullet box recognition model, and outputting the type corresponding to the valid information through the bullet box recognition model;

[0030] S104: When the type corresponding to the valid information is an abnormal type, determining the source of the abnormality according to the abnormal type and tax knowledge associated with the abnormal type;

[0031] S105: Process the exception corresponding to the pop-up window according to the source causing the exception, so that the tax declaration can return to the normal declaration stage.

[0032] In the embodiment of the present invention, when the financial personnel of an enterprise file tax declarations, the corresponding pop-up box images are obtained by collecting the pop-up boxes that appear, and the valid information in the pop-up box images is identified. The valid information is valuable content. The type corresponding to the valid information is identified through a pop-up box recognition model. When the type is an abnormal type, that is, an abnormal problem is encountered, the source of the abnormality is determined according to the abnormal type and the tax knowledge associated with the abnormal type, thereby achieving analysis of the abnormal valid information, and being able to provide the financial personnel with correct problem location, analysis and professional guidance, reduce the data analysis work of the financial personnel, thereby quickly handling the problem of tax declaration, and greatly speeding up the tax declaration.

[0033] Further, S102: identifying data in the pop-up picture, and extracting valid information carried in the data, including:

[0034] The data in the pop-up picture is recognized by OCR technology, and meaningful information is extracted from the data. OCR technology can quickly recognize a large amount of text and image information, greatly increasing the speed of recognizing effective information in the data in the pop-up picture.

[0035] Further, S103: inputting the valid information into a trained pop-up box recognition model, and outputting the type corresponding to the valid information through the pop-up box recognition model, including:

[0036] The meaningful information is input into a trained pop-up recognition model, and the meaningful information is recognized by the pop-up recognition model. The category that matches the meaningful information to a preset value is used as the category corresponding to the meaningful information, and the category corresponding to the meaningful information is output. The pop-up recognition model automatically determines the category corresponding to the information, and prepares for the subsequent automatic determination of the source of the anomaly. It does not require financial personnel to conduct manual analysis in person, reducing the data analysis work of financial personnel, thereby quickly handling tax declaration issues and greatly speeding up tax declaration.

[0037] Furthermore, the types corresponding to the valid information refer to but are not limited to one of the following: failed login, enterprise failure to report, enterprise input not confirmed, wrong declaration form, missing data in declaration form, declaration failure, data verification error, failed transfer, blockage, risk warning, successful declaration pending transfer, successful declaration without transfer, successful transfer, no declaration required, continued execution, and manual inspection. By classifying the types corresponding to the valid information, when this method is used to determine whether the valid information in the pop-up picture is abnormal, the type is first determined, and the specific type is automatically and quickly determined from the classification, without the need for financial personnel to conduct manual analysis, thereby increasing the speed of tax declaration.

[0038] Furthermore, the blocking means that the current tax declaration of the tax type needs to be declared after the previous tax declaration of the tax type. If the previous tax declaration of the tax type is not completed, the current tax declaration is blocked, or it means that before the current tax declaration of the tax type, the current tax declaration of the tax type by the affiliated enterprises of the enterprise needs to be completed. If the current tax declaration of the tax type by the affiliated enterprises of the enterprise is not completed, the current tax declaration is blocked; for specific scenarios, for example, it is necessary to analyze the nature of the enterprise; for example, the financial statements of the branch of the head office need to be completed by the head office, and the branch can only declare the financial statements after the data of the branch is evenly allocated. For example, stamp tax declaration: the tax bureau requires stamp tax to be declared quarterly, and it needs to be declared according to the tax type determined by the tax fee. Even if the amount is 0, it needs to be declared, otherwise it will be regarded as underreporting. These can all be classified as blocking types.

[0039] The risk warnings mentioned above refer to policy document reminders about taxes and fees, reminders about declaration risks, or early warning reminders. Risk warnings are new pop-up boxes that appear as the tax bureau continues to upgrade and issue policy reminders. Most of these warnings can be skipped.

[0040] The manual inspection is used to deal with new anomalies that are temporarily caused by temporary reasons. After the temporary reasons disappear, no new anomalies will be generated;

[0041] Failure of enterprise to make a copy, unconfirmed enterprise input, declaration failure, remittance failure, incorrect declaration form filling, missing data in declaration form, declaration failure and data verification error are all analysis-related and require specific analysis to determine the source of the abnormality.

[0042] The errors in filling out the declaration forms, the missing data in the declaration forms, the declaration failures and the data verification errors are all exceptions between declaration forms. The source of the exceptions between declaration forms is the data exceptions in the current declaration form caused by the declaration errors in other declaration forms, or the errors in other declaration forms caused by the declaration errors in the next level declaration forms that constitute other declaration forms. The errors in other declaration forms further lead to data exceptions in the current declaration form.

[0043] Furthermore, the method for handling abnormal tax declarations also includes:

[0044] S106: The types of declaration rules corresponding to the various types of exceptions are sorted out in advance, the tax knowledge related to the types of declaration rules are sorted out in advance, and the types of declaration rules and the related tax knowledge are saved. The types of declaration rules include basic information verification, submission order verification, report compliance verification, and bureau-side report verification. By sorting out the types of declaration rules and related tax knowledge corresponding to the types of exceptions, the specific source of the exception can be quickly determined based on the types of declaration rules and related tax knowledge corresponding to the types of exceptions, without the need for financial personnel to conduct manual analysis, thereby improving the speed of tax declaration.

[0045] Furthermore, the type of the declaration rule corresponding to the login failure is basic information verification;

[0046] The type of reporting rule corresponding to the enterprise's failure to report is any one of submission order verification, report compliance verification and local end report verification;

[0047] The type of declaration rule corresponding to the enterprise input item not confirmed is any one of submission sequence verification, report compliance verification and bureau-side report verification;

[0048] The type of reporting rule corresponding to the error in filling out the reporting form is any one of submission order verification, report compliance verification and local end report verification;

[0049] The type of declaration rule corresponding to the missing data in the declaration form is any one of submission order verification, report compliance verification and local end report verification;

[0050] When the declaration failure is the failure to declare a financial report, the corresponding declaration rule type is any one of submission order verification, report compliance verification and bureau-side report verification, wherein the declaration failure refers to the failure to declare a financial report, submission failure, or missing data segment;

[0051] The type of reporting rule corresponding to the data verification error is any one of submission order verification, report compliance verification and local end report verification;

[0052] The type of reporting rule corresponding to the failed transfer is any one of submission order verification, report compliance verification and local end report verification;

[0053] The type of declaration rule corresponding to the blocking is submission order verification;

[0054] The risk warning refers to a document warning related to tax and fee policies, or a warning of declaration risks, or an early warning reminder;

[0055] The manual inspection corresponds to any type of report compliance verification and local end report verification.

[0056] Further, S104: when the type corresponding to the valid information is an abnormal type, determining the source of the abnormality according to the abnormal type and tax knowledge associated with the abnormal type, including:

[0057] S104-1: When the type corresponding to the valid information is an abnormal type, determine the type of the corresponding reporting rule according to the abnormal type;

[0058] S104-2: Acquire tax knowledge related to the type of declaration rule according to the type of corresponding declaration rule;

[0059] S104-3: Determine the source of the anomaly based on the tax knowledge associated with the anomaly type.

[0060] When the type of valid information carried by the data in the pop-up picture corresponds to an abnormal type, it indicates that there is an abnormality in the tax declaration. First, determine the type of corresponding declaration rule based on the abnormal type, and then obtain tax knowledge related to the type of declaration rule based on the type of corresponding declaration rule. The source of the abnormality can be determined, so that the tax declaration can return to the normal declaration stage.

[0061] Furthermore, the method for handling tax declaration anomalies also includes S107: pre-training a pre-trained model BERT, a long short-term memory network LSTM and a self-attention deep learning recognition model to obtain a trained pop-up box recognition model, wherein S107: pre-training a self-attention deep learning recognition model to obtain a trained pop-up box recognition model includes:

[0062] S107-1: Use the pictures corresponding to the first massive abnormal pop-up boxes generated in the tax declaration process of historical tax types as training samples, manually extract the valid information carried in the training samples, and use different labels to distinguish the types corresponding to the valid information; the tax types include at least one of the following: general taxpayer value-added tax, small-scale value-added tax, corporate income tax, financial statements, disability employment security fund, water conservancy construction fund, union dues, stamp duty, real estate tax, urban land tax, consumption tax and environmental protection tax;

[0063] S107-2: Based on the effective information and corresponding types carried by the first massive abnormal images, the self-attention deep learning recognition model is trained to obtain a pop-up box recognition model in the training process;

[0064] S107-3: recognizing data in the second massive abnormal images by using OCR technology, and extracting valid information carried in the data in the second massive abnormal images;

[0065] S107-4: inputting the valid information in the second massive abnormal pictures into the pop-up box recognition model in the training process, identifying the valid information in the second massive abnormal pictures through the pop-up box recognition model in the training process, outputting the categories corresponding to the valid information in the second massive abnormal pictures, and judging whether the pop-up box recognition model in the training process has been trained according to the accuracy of the output categories;

[0066] S107-5: When the accuracy of the output type is lower than the accuracy threshold (for example, 95%), the pop-up box recognition model in the training process continues to be trained until the accuracy of the output type is not lower than the accuracy threshold. The training is completed and a trained pop-up box recognition model is obtained.

[0067] The abnormal pop-up boxes generated during tax declaration are used as training samples, and valuable content, i.e., valid information, in the abnormal pop-up boxes are extracted. Then, they are classified and labeled according to the types corresponding to the valid information. The training samples are trained for semantic recognition through the self-attention deep learning recognition model to build a pop-up recognition model. When declaring taxes, a pop-up picture is collected, and the type of valid information in the pop-up picture is determined by the pop-up recognition model. When the type is an abnormal type, the source of the abnormality is determined in combination with relevant tax knowledge, which can provide technical guidance for the handling of abnormal pop-ups, and does not require financial personnel to conduct manual analysis in person. Therefore, the intelligent method of the pop-up recognition model of the embodiment of the present invention reduces labor costs and improves the speed of tax declaration.

[0068] like Figure 2 As shown, in combination with an embodiment of the present invention, a system for processing tax declaration anomalies is provided, comprising:

[0069] The pop-up frame collection unit 21 is used to collect the pop-up frames that appear in the form of images when the enterprise declares any tax type, and obtain the corresponding pop-up frame images;

[0070] An information identification unit 22, used to identify the data in the pop-up picture and extract the valid information carried in the data;

[0071] A category determination unit 23, configured to input the valid information into a trained bullet box recognition model, and output the category corresponding to the valid information through the bullet box recognition model;

[0072] The abnormality determination unit 24 is used to determine the source of the abnormality according to the abnormality type and the tax knowledge associated with the abnormality type when the type corresponding to the valid information is an abnormal type;

[0073] The exception resolution unit 25 is used to process the exception corresponding to the pop-up box according to the source causing the exception, so that the tax declaration can return to the normal declaration stage.

[0074] When the company's financial personnel file tax returns, they collect the pop-up boxes that appear, obtain the corresponding pop-up box images, identify the valid information in the pop-up box images, and use the pop-up box recognition model to identify the type corresponding to the valid information. When the type is an abnormal type, that is, when an abnormal problem is encountered, the source of the abnormality is determined based on the abnormal type and the tax knowledge associated with the abnormal type, thereby analyzing the abnormal valid information. This can provide financial personnel with correct problem location, analysis and professional guidance, reduce the data analysis work of financial personnel, and thus quickly handle tax declaration issues, greatly speeding up the tax declaration process.

[0075] Furthermore, the information identification unit 22 is specifically used for:

[0076] The data in the pop-up picture is recognized by OCR technology, and meaningful information is extracted from the data. OCR technology can quickly recognize a large amount of text and image information, greatly increasing the speed of recognizing effective information in the data in the pop-up picture.

[0077] Furthermore, the type determination unit 23 is specifically configured to:

[0078] The meaningful information is input into a trained pop-up recognition model, and the meaningful information is recognized by the pop-up recognition model. The category that matches the meaningful information to a preset value is used as the category corresponding to the meaningful information, and the category corresponding to the meaningful information is output. The pop-up recognition model automatically determines the category corresponding to the information, and prepares for the subsequent automatic determination of the source of the anomaly. It does not require financial personnel to conduct manual analysis in person, reducing the data analysis work of financial personnel, thereby quickly handling tax declaration issues and greatly speeding up tax declaration.

[0079] Furthermore, the types corresponding to the valid information refer to but are not limited to one of the following: failed login, enterprise failure to report, enterprise input not confirmed, wrong declaration form, missing data in declaration form, declaration failure, data verification error, failed transfer, blockage, risk warning, successful declaration pending transfer, successful declaration without transfer, successful transfer, no declaration required, continued execution, and manual inspection. By classifying the types corresponding to the valid information, when the system is used to determine whether the valid information in the pop-up picture is abnormal, the type is first determined, and the specific type is automatically and quickly determined from the classification, without the need for financial personnel to conduct manual analysis, thereby increasing the speed of tax declaration.

[0080] Furthermore, the blocking means that the current tax declaration of the tax type needs to be declared after the previous tax declaration of the tax type. If the previous tax declaration of the tax type is not completed, the current tax declaration is blocked, or it means that before the current tax declaration of the tax type, the current tax declaration of the tax type by the affiliated enterprises of the enterprise needs to be completed. If the current tax declaration of the tax type by the affiliated enterprises of the enterprise is not completed, the current tax declaration is blocked; for specific scenarios, for example, it is necessary to analyze the nature of the enterprise; for example, the financial statements of the branch of the head office need to be completed by the head office, and the branch can only declare the financial statements after the data of the branch is evenly allocated. For example, stamp tax declaration: the tax bureau requires stamp tax to be declared quarterly, and it needs to be declared according to the tax type determined by the tax fee. Even if the amount is 0, it needs to be declared, otherwise it will be regarded as underreporting. These can all be classified as blocking types.

[0081] The risk warnings mentioned above refer to policy document reminders about taxes and fees, reminders about declaration risks, or early warning reminders. Risk warnings are new pop-up boxes that appear as the tax bureau continues to upgrade and issue policy reminders. Most of these warnings can be skipped.

[0082] The manual inspection is used to deal with new anomalies that are temporarily caused by temporary reasons. After the temporary reasons disappear, no new anomalies will be generated;

[0083] Failure of enterprise to make a copy, unconfirmed enterprise input, declaration failure, remittance failure, incorrect declaration form filling, missing data in declaration form, declaration failure and data verification error are all analysis-related and require specific analysis to determine the source of the abnormality.

[0084] The errors in filling out the declaration forms, the missing data in the declaration forms, the declaration failures and the data verification errors are all exceptions between declaration forms. The source of the exceptions between declaration forms is the data exceptions in the current declaration form caused by the declaration errors in other declaration forms, or the errors in other declaration forms caused by the declaration errors in the next level declaration forms that constitute other declaration forms. The errors in other declaration forms further lead to data exceptions in the current declaration form.

[0085] Furthermore, the tax declaration exception processing system also includes:

[0086] The tax knowledge sorting unit is used to sort out the types of declaration rules corresponding to each of the above-mentioned exception types in advance, sort out the tax knowledge related to the types of declaration rules in advance, and save the types of declaration rules and related tax knowledge. The types of declaration rules include basic information verification, submission order verification, report compliance verification, and bureau-side report verification. By sorting out the types of declaration rules and related tax knowledge corresponding to the exception types, it is possible to quickly determine the specific source of the exception based on the types of declaration rules and related tax knowledge corresponding to the exception types in the future, without the need for financial personnel to conduct manual analysis, thereby improving the speed of tax declaration.

[0100] Acquire tax knowledge related to the type of declaration rule according to the type of corresponding declaration rule;

[0101] Based on the tax knowledge associated with the abnormal type, the source causing the abnormality is determined.

[0102] When the type of valid information carried by the data in the pop-up picture corresponds to an abnormal type, it indicates that there is an abnormality in the tax declaration. First, determine the type of corresponding declaration rule based on the abnormal type, and then obtain tax knowledge related to the type of declaration rule based on the type of corresponding declaration rule. The source of the abnormality can be determined, so that the tax declaration can return to the normal declaration stage.

[0103] Furthermore, the tax declaration exception processing system also includes:

[0104] The pop-up box recognition model construction unit is used to pre-train the pre-trained model BERT, long short-term memory network LSTM and self-attention deep learning recognition model to obtain a trained pop-up box recognition model; wherein, the pop-up box recognition model construction unit is specifically used to:

[0105] The pictures corresponding to the first massive abnormal pop-up boxes generated in the tax declaration process of historical tax types are used as training samples, and the valid information carried by them is manually extracted from the training samples, and different labels are used to distinguish the types corresponding to the valid information; the tax types include at least one of the following: general taxpayer value-added tax, small-scale value-added tax, corporate income tax, financial statements, employment security fund for the disabled, water conservancy construction fund, union dues, stamp duty, real estate tax, urban land tax, consumption tax and environmental protection tax;

[0109] When the accuracy of the output type is lower than the accuracy threshold (for example, 95%), the pop-up box recognition model in the training process continues to be trained until the accuracy of the output type is not lower than the accuracy threshold. The training is completed and a trained pop-up box recognition model is obtained.

[0110] The abnormal pop-up boxes generated during tax declaration are used as training samples, and valuable content, i.e., valid information, in the abnormal pop-up boxes are extracted. Then, they are classified and labeled according to the types corresponding to the valid information. The training samples are trained for semantic recognition through the self-attention deep learning recognition model to build a pop-up recognition model. When declaring taxes, a pop-up picture is collected, and the type of valid information in the pop-up picture is determined by the pop-up recognition model. When the type is an abnormal type, the source of the abnormality is determined in combination with relevant tax knowledge, which can provide technical guidance for the handling of abnormal pop-ups, and does not require financial personnel to conduct manual analysis in person. Therefore, the intelligent method of the pop-up recognition model of the embodiment of the present invention reduces labor costs and improves the speed of tax declaration.

[0111] The beneficial technical effects achieved by the embodiments of the present invention are as follows:

[0112] When declaring taxes and fees, collect pop-up images, extract valid information from the pop-up images, determine the type of valid information through the pop-up recognition model, and when it is an abnormal type, determine the source of the abnormality in combination with relevant tax knowledge, and provide professional advice and analysis for financial personnel, greatly reducing the workload of financial personnel in troubleshooting abnormalities, and realizing rapid processing of declared abnormalities, greatly shortening the tax declaration cycle. For financial personnel of group companies, when declaring taxes and fees, the pop-up image recognition method is used to quickly extract valid information, analyze the valid information, and provide professional processing solutions, which greatly speeds up the company's declaration speed. For small companies, professional data analysis can greatly reduce the speed of the declaration process, and the use of image recognition greatly reduces the operator's operability.

[0113] Example 1: When a general taxpayer of an enterprise reports VAT, it is necessary to process the tax disk for each tax period to copy and clear the card, print the relevant output data, summarize the declaration data, pull the input data, summarize the input declaration, and sort out the declaration data according to the nature of the enterprise.

General taxpayers must fill in at least 6 forms ("Balance Sheet", "Profit and Loss Statement", "Fixed Asset Input Tax Deduction Status Form", "Output Tax (Form 1)", "Input Tax (Form 2)", and "VAT Return Form"). The following are examples of the relationship between the VAT returns of general taxpayers: (1) The "Current Month Amount" and "Output Tax Amount" in the "General Items" column of the 11th column of the VAT main form are derived from the "Attached Information (I)" (the sum of the 1st and 3rd columns of the 10th column - the 6th column of the 10th column) + (the sum of the 2nd, 4th and 5th columns of the 14th column - the 7th column of the 14th column); (2) The "Current Month Amount" and "Input Tax Amount" in the "General Items" column of the 12th column of the VAT main form are derived from the "Tax Amount" in the 12th column of the "Attached Information (II)"; (3) The "Current Month Amount" and "Input Tax Amount Transferred Out" in the "General Items" column of the 14th column of the VAT main form are derived from the "Tax Amount" in the 13th column of the "Attached Information (II)"; (4) The "General Items" column of the 21st column of the VAT main form are derived from the "Tax Amount" in the 21st column of the "Attached Information (II)"; The "Current Month Amount" and "Tax Payable Calculated by Simplified Tax Calculation Method" in the "Attachment (I)" column are derived from (the sum of rows 8, 9a, 10 and 11 in column 10 - row 14 in column 10) + (the sum of rows 9b, 12, 13a and 13b in column 14 - row 15 in column 14); (5) The "Total Price and Tax of Services, Real Estate and Intangible Assets in this Period (Tax-free Sales)" in column 1 of the "Attachment (I)" column are derived from the corresponding rows in column 11 of the "Attachment (I)", where the sum of rows 3 and 4 of this column is equal to the fifth column in column 11 of the "Attachment (I)"; (6) The "Value Added Tax Amount" in column 1 of the "Attachment (V)" column is derived from the value added tax payable (refundable) in this period in column 34 of the main table.

[0114] During the declaration process, the tax bureau often displays different error prompts, and the error information prompts are relatively general. Most data error prompts come from the accumulation of data from different reports. Such error prompts often require strong professional knowledge to analyze. Therefore, the method and system of the embodiment of the present invention can be used to process abnormal pop-up pictures to assist enterprises in quickly declaring general taxpayers' value-added tax, such as Figure 3 shown.

[0115] Example 2: When an enterprise declares stamp tax, it enters the tax bureau declaration system and selects the corresponding stamp tax declaration according to the nature of the enterprise. It first collects tax source information, and then fills in the corresponding tax source information declaration data based on the collected tax source information and submits the declaration. However, when declaring stamp tax, enterprises often fail to report tax items. Therefore, the method and system of the embodiment of the present invention can be used to process abnormal pop-up images, and combined with the stamp tax item related information of the enterprise's tax assessment information, analyze whether the enterprise has failed to report, such as Figure 4 As shown, in order to give enterprises an early warning.
