If the VAT notice is not being sent from 1C, the most common reason is an incorrectly prepared inventory (TMZ) document, which causes the VAT amount to differ from the expected one. It is precisely this discrepancy that blocks the sending of the notice. Solution: find the error in the inventory document, correct it so that the VAT amount matches the correct one, after which the notice will be sent without problems. Why the notice is not being sent The notice (notification) in the electronic invoice system is generated based on the data of primary documents. If the VAT amount in the inventory document (inventory and materials) does not correspond to the one expected for the transaction, the system regards this as a discrepancy and does not allow the notice to be sent. Until the data is put in order, sending remains blocked. As a rule, the error occurs already at the stage of filling in the inventory receipt or sales document: the rate is specified incorrectly, the amount excluding VAT is calculated incorrectly, the analytics by item "dropped off," or the VAT accounting procedure was chosen incorrectly. As a result, the calculated tax amount differs from the correct one, and this blocks further actions. What needs to be done The main task is to find the inventory document with the error and eliminate the discrepancy in the VAT amount. - Open the inventory document for which the notice is not going through and check how it is filled in — most likely, it contains the error that led to the incorrect VAT calculation. - Find the discrepancy: compare the VAT amount reflected in the document with the one that should result from the actual transaction. - Correct the document so that the VAT amount matches the correct one. - Re-post the document and repeat sending the notice — after correction, it should be sent without problems. Step-by-step reconciliation if the error is not immediately visible If it is difficult to find the discrepancy visually, it is better to reconcile line by line. This is the most reliable way to localize the problem. - Go through each line of the tabular part of the inventory document and compare the VAT amounts in 1C with those that should result from the actual transaction. - Pay attention to lines where the VAT amount differs from the expected one by at least a kopeck — these are usually the ones that produce the discrepancy. - Check that for each item the VAT rate is specified correctly and the amount excluding tax, including tax, and the VAT itself are calculated correctly. - Make sure that the total for the document matches the sum of the lines — sometimes the discrepancy arises due to rounding or manual editing of the total fields. Once the discrepancy is found and eliminated, the document is brought to a correct form, and the notice stops being blocked. What else to pay attention to in the inventory document For the VAT amount to be calculated correctly, check the basic details of the document: - The VAT rate for each item — it must correspond to the nature of the transaction and the type of item. - The VAT accounting procedure — whether the tax is included in the price or charged on top; an error here directly changes the calculated amount. - The item and its settings — whether the data for the item was pulled in correctly, whether there is duplication or unfilled fields. - Quantity, price, and amount — the arithmetic per line must be consistent, without manual edits that "break" the VAT calculation. - Posting of the document — the document must be posted; an unposted or partially posted document may also interfere with the generation of the notice. Typical errors - The VAT rate is specified incorrectly in a line of the tabular part, causing the calculated tax amount to differ from the correct one. - Manual adjustment of the VAT amount or total, which desynchronized the lines and the "header" of the document. - The VAT accounting procedure (in the price / on top) was chosen incorrectly, which gives a different tax amount. - The inventory document was not re-posted after making corrections — the old data remains in the accounting, and the discrepancy persists. - An attempt to resend the notice without eliminating the root cause in the inventory document. What to check - Whether the VAT amount in the inventory document matches the one that should result from the actual transaction. - Whether each line of the tabular part is filled in correctly: rate, amount excluding VAT, VAT amount, total. - Whether the total amounts for the document are consistent with the amounts by lines. - Whether the inventory document is posted (and re-posted after correction). - Whether the notice is sent after the discrepancy is eliminated — if so, the problem was precisely in the inventory document. Conclusion: the VAT notice is not being sent due to a discrepancy in the tax amount in the inventory document. Find the error in filling in the document (if necessary, by line-by-line reconciliation), correct it so that the VAT amount becomes correct, re-post the document, and the notice will be sent without problems. --- _BuhGPT — ИИ-помощник для бухгалтеров Казахстана: https://buhgpt.kz_
