How to appeal a mistake in a tax notice: instructions from a lawyer If the tax notice indicates someone else's apartment, a car that was sold or the required benefit was not taken into account, you can appeal the accrual. The main thing is not to ignore the mistake and raise objections in time, said lawyer Oleg Rodikov. Check the data first. Check the information in the message with your documents. Errors in the characteristics of the property, the period of ownership or the application of the benefits may become the basis for recalculation. Submit your request. For this, form KND 1150139 is used. It can be sent through the taxpayer's personal account, the Taxes FL application, MFC, by mail or in person to the tax office. State exactly what you disagree with and attach supporting documents. Wait for an answer. Normally, the request is reviewed within 30 working days. In some cases, the period can be extended by another 30 days. During the return, the disputed amount is not included in the balance of the individual tax account and is not deleted. If refused, appeal. A complaint to a higher tax authority can be submitted within 30 working days. You are allowed to go to court after the pre-trial procedure is over. Don't confuse an error with a delay. If you do not agree with the accrual and file an objection, the debt is considered disputed and is not collected out of court. If the amount is correct, but you simply did not pay on time, the assessment authority can send an order to the bank without going to court. "The main thing is not to ignore the mistake and to raise objections in time: this makes it possible to stop the extrajudicial collection and correct the wrong accumulation without going to court," emphasized Rodikov.
