The error is most often related specifically to a particular instance of the report that was created earlier and contains incorrect data or a failure in the file structure. Recreating removes the problem, and the new export goes through correctly. Why the 300.00 export error occurs Form 300.00 is VAT tax reporting that VAT payers submit to the state revenue authorities (SRC). In 1C:Accounting for Kazakhstan, the report is generated as a separate instance of a regulated report, and then exported to a file of the established format for submission through the taxpayer's cabinet or the tax return (FNO) acceptance system. A failure at the export stage means that the program was unable to correctly generate the output file from this report instance. Typical causes related specifically to an already created report instance: - a failure in the structure of the generated file during filling or subsequent editing; - incorrect or "hanging" data in a specific report instance, left over after manual edits; - partial filling of the report, interrupted by a session or configuration update; - corruption of a report instance created in an earlier version of the form. What to do: step-by-step procedure Do not try to correct or re-export an already generated report in which the error occurred. Instead, perform a recreation: - Delete the current, problematic version of the 300.00 report. - Create a new report from scratch for the same tax period. - Fill in and generate the form again. - Repeat the file export. In most cases, after recreation the new export goes through without errors, since the new report instance is generated on up-to-date data and in a correct structure. If the error recurs after recreation If the error recurs after recreating the report, this is already a reason for more detailed diagnostics, since the cause may be deeper: in the declaration data itself or in the program settings. In this case, check the following areas in order. 1. Relevance of the configuration and report form - Make sure that the current version of the 1C:Accounting for Kazakhstan configuration is installed and that the regulated reporting forms are updated. The 300.00 export format changes periodically, and an outdated form may not comply with the requirements of the receiving gateway. - Check that the correct period and edition of form 300.00, valid for the reporting period, are selected. 2. Correctness of the declaration data - Check the completion of the mandatory taxpayer details (BIN/IIN, name, codes, attributes). - Check the amount indicators of the lines for non-empty and logically correct values, as well as the interconnection of the sections and appendices of the form. - If appendices are generated for 300.00 (registers of invoices, etc.), make sure that the ESF data is pulled in completely and without duplicates. - Pay attention to special characters, incorrect dates and empty mandatory fields — they often break the structure of the exported file. 3. Settings of the program and environment - Check the organization settings: taxation system, VAT payer attribute, reporting details. - Make sure that the path for saving the export file is accessible and that the user has write permissions. - Check that there is free space on the disk and that the file is not blocked by the antivirus. How to check the report before export To reduce the likelihood of a recurring error, use the built-in check before exporting: - run the check of the form's control ratios using 1C tools; - eliminate all remarks that the program displays based on the check results; - only after a successful check, generate the export file. Typical mistakes - Trying to re-export a "broken" instance. Repeatedly exporting the same problematic report yields no result — a new instance is needed. - Manual edits in an already generated report. Point-by-point correction of numbers "on top of" the generated form often leads to a failure in the file structure. - Working on an outdated form. Exporting in the old format when the acceptance requirements have changed. - Ignoring check remarks. Exporting when there are warnings about control ratios. - An unclosed or partially reflected period for VAT and ESF — the data is pulled into the form incompletely. What to check - Whether the problematic instance has been deleted and the 300.00 report has been recreated. - Whether the configuration version and the regulated reporting form are up to date. - Whether the built-in check of control ratios has been passed without errors. - Whether the organization details and the VAT payer attribute are correct. - Whether the period data and ESF that go into the declaration are fully reflected. - Whether the file save path is accessible and whether the antivirus is not blocking it. - If the error persists — record the exact error text and contact a 1C support specialist for detailed diagnostics. --- _BuhGPT — ИИ-помощник для бухгалтеров Казахстана: https://buhgpt.kz_
