If form 300.00 was uploaded to the Taxpayer's Cabinet without register 300.02, and when trying to add data manually the system returns an error, the issue is not with 1C. The check showed that the document is generated correctly in 1C, with no errors in the program. The problem lies on the side of the Taxpayer's Cabinet service.
What was done during the check
Specialists checked the data in 1C and confirmed: form 300.00 is generated without violations, all data is correct. The error when adding register 300.02 occurs specifically in the Taxpayer's Cabinet, not in the accounting program.
To clarify the cause, screenshots of the error and additional data were requested — they were passed on to colleagues for more detailed analysis. The check confirmed that the problem is indeed related to the operation of the Taxpayer's Cabinet service itself.
What to do in this situation
Since the error is not related to 1C, it needs to be resolved through the technical support of the Taxpayer's Cabinet. It is recommended to contact them directly, attaching screenshots of the error and a description of the situation — this will speed up the review of the request.
In the case described, the client did just that: contacted Taxpayer's Cabinet support and confirmed that the request had been sent.
Frequently Asked Questions
Could the cause still be in 1C if the register does not load?
In this case, the check clearly showed no errors on the 1C side — the form is generated correctly. Such situations, where register upload fails despite confirmed correctness of the form, indicate a problem with the receiving service.
Do I need to regenerate the form in 1C before resubmitting to the Taxpayer's Cabinet?
If 1C does not detect any errors in generating the document, there is no need to regenerate the form — the problem is resolved on the Taxpayer's Cabinet support side.
Where should I go if the error recurs?
You should send a request to the technical support of the Taxpayer's Cabinet with screenshots of the error attached — this is the channel responsible for such service failures.
