The annual VAT return: who owes it, by when, and what falls due afterwards

A graphic designer filed twelve advance returns on time in 2025, prepaid 11,400 € through them, and considers the year closed. In October 2026 a letter arrives: the annual return is missing and a surcharge is looming. She had assumed that the twelve filings together made up the return. The law sees it differently, and gives the annual return its own paragraph, its own deadline and its own payment date.

A second calculation covering the whole year

The course on the German VAT advance return covers the in-year rhythm: period, ten-day deadline, permanent deadline extension and special prepayment. This module starts where that course stops, after the last advance-return period of the year. Anyone not yet confident with the advance return should read that course first.

§ 18(3) UStG requires a separate return for the calendar year. In it the business works out the tax payable, or a surplus in its favour, on its own and transmits the result electronically. The statute expressly calls this return a tax self-assessment, exactly like the monthly or quarterly filing.

Even so, it is not a sum. The advance returns are provisional interim figures; the annual return is the final settlement. Between the two there are usually corrections: a forgotten purchase invoice, a down payment booked to the wrong period, an adjustment after a bad debt. All of that belongs in the annual calculation, not in yet another advance return.

That is why the ELSTER form asks for the whole year's sales and input tax again in full, split by tax rate. Anyone who simply adds up the twelve advance-return results carries every error of the year unchanged into the final figure, and wastes the one chance to clean it up without a separate correction.

A complete annual calculation also includes the exempt supplies that create no liability. § 18b UStG requires the taxable amounts of intra-EU supplies to be stated separately in every advance return and in the annual return. The second module shows why that figure has to match another filing sent to a different authority.

Who must file, even without a single advance return

The duty to file the annual return does not depend on whether advance returns were due during the year. A business released from advance returns under § 18(2) UStG because its tax was very low is released from those alone. The return for the calendar year remains, and it is then the only filing of the year.

The small-business owner is in a different position. § 19(1) sentence 2 UStG switches off the filing duties of § 18(1) to (4) for them. The course on the small-business scheme covers this exception in detail; here one point that is often overlooked is enough: § 149(1) sentence 2 AO expressly continues to apply.

That sentence of the Fiscal Code obliges anyone to file whom the tax authority asks to do so. A request therefore turns even a small-business owner into someone who owes a return. Whoever receives such a letter cannot answer it by pointing to § 19 UStG, but has to submit the return.

• every business that is not under the small-business scheme, even if it had no advance return to file
• anyone released from advance returns under § 18(2) sentence 3 UStG
• anyone who owes tax only as a recipient, for instance under § 13b(5) UStG (§ 18(4a) UStG)
• a small-business owner whom the tax office expressly asks to file

The third item covers cases that many people do not see as business activity. Someone who owes the tax as recipient files advance returns under § 18(4a) UStG only for the periods in which such amounts arise, and a return at the end of the year. The duty follows the tax amount, not the size of the business.

Seven months, or until the end of February of the year after next

The VAT Act itself sets no deadline for the annual return. It relies tacitly on the Fiscal Code, where § 149(2) AO governs the basic case: returns relating to a calendar year are due no later than seven months after that year ends. For the year 2025, this deadline ends on 31 July 2026.

Paragraph 3 extends the deadline when a tax adviser has been engaged to prepare the return. The annual VAT return is expressly on that list, as item 4. The deadline then becomes the last day of February in the second year after the tax period, so for 2025 it is 28 February 2027.

Counted from the end of the year, that is fourteen months instead of seven. The difference is substantial and explains why many business owners only see their return in the spring of the year after next. It applies only if an adviser has actually been engaged to prepare it, not merely because an adviser was involved at some point.

The extended deadline is also conditional. Under § 149(4) AO the tax office may call for the return earlier, for example when the previous year's return was late or never filed, or when a large balancing payment is expected. Such an order displaces the February date in that particular case.

A warning about older guidance leaflets: for the tax periods 2020 to 2024, longer transitional deadlines applied under Article 97 § 36 EGAO. For advised cases of the year 2024, it ran until 30 April 2026. For 2025 the provision contains no further deviation, and the basic model applies again.

Missing the deadline is not cured by the tax office making an estimate. § 149(1) AO makes clear that the duty to file continues even after the tax bases have been estimated. The estimated assessment therefore does not replace the return, it comes on top of it, usually with an unfavourable figure.

If the business ends during the year, only one month remains

Under § 16(1) UStG the tax period is, as a rule, the calendar year. If the activity was carried on for only part of the year, paragraph 3 puts that part in place of the year. Paragraph 4 also lets the tax office set a shorter period where collection of the tax seems at risk or the business agrees.

For these two cases § 18(3) sentence 2 UStG has its own very short deadline: the return must be transmitted within one month after the shortened period ends. A business closed at the end of June therefore has until the end of July, not until the summer of the following year.

This deadline is regularly missed because it sits outside the usual annual logic. ELSTER therefore offers the form for the current year as well. Anyone planning to close a business should put the date in the calendar at the same time as deregistering the trade.

In hardship cases § 18(3) sentence 3 UStG allows, on application, the official paper form instead of electronic transmission. Unlike the advance return, this paper return must be signed by hand. An unsigned paper version is therefore not a valid filing, even if it lands in the tax office letterbox in time.

The balancing payment has its own due date

If the annual calculation shows more tax than the total of the advance payments, the difference is not due on filing. § 18(4) sentence 1 UStG sets the due date at one month after the tax office receives the self-assessment. What counts is receipt, not the date the business writes in its own records.

By its wording, this one-month period applies only to an amount in favour of the tax office. If the return shows a surplus in favour of the business, that sentence contains no corresponding rule. For the refund, § 168 sentence 2 AO applies: a self-assessment leading to a refund only takes effect as an assessment once the tax office consents.

If the tax office assesses a different figure from the one filed, or estimates for lack of a return, sentence 2 moves the reference point: the difference is then due one month after the assessment notice is issued. So the business never pays on the same day it first learns the figure.

Sentence 3 rules out an obvious hope. Overdue advance payments remain due on their original date, whenever the annual return arrives. A business that did not pay in November cannot move that debt into the balancing payment, and the late-payment surcharge for November keeps running.

For cash planning, this means one month of room that can be scheduled. Filing in early May means paying in early June; holding the return until the end of July moves the payment back accordingly. The timing of the filing therefore steers the timing of the payment, as long as the statutory deadline is met.

Special prepayment and deadline extension at year end

Businesses using the permanent deadline extension ask whether it also covers the annual return. It does not. § 46 UStDV refers only to the advance returns and advance payments under § 18(1), (2) and (2a) UStG. The deadlines for the annual return follow the Fiscal Code alone and are unaffected.

A monthly filer's special prepayment is not set off in the annual return but earlier. § 48(4) UStDV has it taken into account in the advance payment for the last advance-return period, which is normally the December advance return. In the annual calculation it then appears only as part of the advance payments already made.

Anyone who forgets the special prepayment in December and tries to deduct it only in the annual return counts it twice or not at all. The calculator for the permanent deadline extension shows how the one-eleventh and the December credit fit together; the calculation itself is taught in the advance-return course.

When the late-filing surcharge becomes mandatory

A late annual return falls under § 152 AO. In principle the tax office may impose a late-filing surcharge and must exercise discretion in doing so. Paragraph 2 reverses this for annual returns: if the return is not received within fourteen months after the calendar year ends, the surcharge must be imposed, with no discretion.

Fourteen months is also the extended deadline in advised cases. Anyone with an adviser who misses the last day of February therefore slides straight into the mandatory surcharge. In the unadvised case there is a buffer of seven months in between, during which a surcharge is possible but not required.

Paragraph 3 exempts several situations from the mandatory rule. For VAT, number 3 matters: if the assessed tax does not exceed the total of the assessed advance payments, the automatic rule falls away. A business that filed its advance returns correctly and owes no top-up is therefore outside the obligation, though still within discretion.

Paragraph 5 sentence 2 sets the amount for year-based returns specifically. The base is the assessed tax minus the assessed advance payments, and the surcharge is 0.25 percent of it for each month or part month, but at least 25 euros per month. The minimum therefore bites precisely when there is little to pay.

An example shows the scale. On a top-up of 2,000 euros, 0.25 percent would come to only 5 euros per month, and the minimum lifts that to 25 euros. After four started months of delay, 100 euros are at stake, for a return whose content had long been settled.

In practice this gives a simple sequence. First determine your own deadline, seven or fourteen months. Then rebuild the annual calculation in full instead of adding up advance returns. Finally record the date of receipt, because the payment date hangs on it, and transfer the money one month later.
