Your computer, internet conne --- Short answer The Taxpayer Cabinet (TC) is not loading: forms do not open, the tax return cannot be submitted, the page freezes, or an error appears. The first thing you need to determine is whether the failure is on the service side or your side. Your computer, internet connection, and 1C may be working perfectly, but the report may still fail to submit because the tax authority's infrastructure service itself is down. What to do right now: do not reinstall everything indiscriminately, and do not panic about the deadline. First, determine exactly where the problem is, and then document your submission attempt. Below, we explain how to distinguish a service failure from a local malfunction in a couple of minutes and what to do if you cannot meet the deadline. How to determine within a minute whether the failure is on the service side or your side Signs that the problem is with the TC service, rather than your equipment: - Other websites and email work normally, but the TC does not. - Your colleagues and other accountants encounter the error at the same time. - The form is generated in 1C without errors but fails when uploaded to the TC. This is a typical case: everything is correct in the accounting software, but the Cabinet itself does not accept it. - Signs that the problem is on your side: - Nothing on the internet opens at all—the issue may be with your provider or Wi-Fi. - The EDS is not detected, the key certificate has expired, or NCALayer does not start. - Only you encounter the error, while the TC works for your colleagues. A quick way to avoid guessing is to check independent automated availability checks. Check the TC status in 5 seconds—BuhGPT Status. This is independent monitoring, not an official source of government authorities; it shows whether the service is responding right now. Who is affected Who you are Consequences of a TC failure Outsourced accountant Forms cannot be submitted for several clients at once IE and LLP The tax return cannot be submitted, jeopardizing the deadline VAT payer Form 300.00 and its registers cannot be uploaded Anyone whose deadline is today Risk of missing the deadline through no fault of their own What to do about a missed deadline If the service is unavailable specifically on the filing date, proceed as follows: - Document the failure. Take screenshots showing the error and time, and save the monitoring page. This is your proof that you tried to submit on time rather than ignored the deadline. - Check the form in the accounting software. If 1C generates the report without errors but the TC itself does not accept it, the problem is not on your side, and this is corroborated by the service-side failure. - Try submitting it again when the service is restored. Do not redo the form “just in case” if it is already correct—you will only create confusion in the data. - Contact TC technical support and attach the screenshots. Errors that occur only in the Cabinet—for example, when working with registers for Form 300.00—must be resolved on their side, not in your software. - Remain calm about the deadlines. A widespread service failure is a strong argument. Keep evidence of your submission attempts readily available and monitor official explanations from the tax authority. We do not state the current availability figure here because it changes every minute. Always check the system page for the latest status. Frequently asked questions How can I tell whether the TC is at fault rather than my computer? — If other websites open, the EDS works, and the form is generated in 1C without errors but fails only when uploaded to the Cabinet, the service is almost certainly the cause. You can confirm this on the monitoring page. Will I be penalized for missing the deadline if the service was down? — Your task is to prove that you tried to submit on time. Save screenshots showing the error and time, and submit the report immediately after the service is restored; in the event of widespread failures, this is a standard and justified situation. Form 300.00 was uploaded without the register—is this a 1C error? — If the accounting software generates the form correctly but the register is not accepted specifically by the Cabinet, the error is on the TC side. Take screenshots and contact the service's support team. Should I reinstall NCALayer and the keys during a failure? — Only if the problem is specifically on your side—the EDS is not detected or NCALayer does not start. Reinstallation will not change anything during a widespread service failure, so check the status first. Where can I check whether the TC is working right now? — On the independent automated availability-check page; the link is provided in the Sources section below.
