If the 10th-of-the-month German VAT deadline is uncomfortably tight, there is a standard, permanent fix: the Dauerfristverlängerung. It is one of the few genuinely useful levers a foreign seller has over the German filing calendar, and it is widely misunderstood because the word is long and the Sondervorauszahlung sounds scarier than it is. Here is exactly how it works and when to use it.

What it is: an extra month, every month

A Dauerfristverlängerung (permanent time extension) shifts your Umsatzsteuer-Voranmeldung (advance VAT return) and its payment by one month. Without it, the return for January is due 10 February. With it, the same return is due 10 March. The extension is permanent: once granted it renews automatically each year, so you are not reapplying every month. It is governed by § 46 UStDV.

The extension applies to the preliminary returns and their payments. It does not move the annual return (Umsatzsteuer-Jahreserklärung) or the Zusammenfassende Meldung (ZM / EC Sales List), which keep their own deadlines.

The Sondervorauszahlung: the price of the extra month

Full guide: the Sondervorauszahlung, how it is calculated and why it is refunded →

Here is the part that trips people up. If you file monthly, the tax office asks for a special advance payment, the Sondervorauszahlung (§ 47 UStDV), in exchange for the extension. It is one eleventh of the total advance payments you made in the previous year, and it is due by 10 February.

Crucially, this is not an extra tax or a fee. It is an advance that gets credited back in full against your December advance return at year end. In cash-flow terms you are lending the Finanzamt roughly one month of VAT for the year; in real-cost terms it is close to nothing. If you file quarterly, there is no Sondervorauszahlung at all, you simply get the extension.

How and when to apply

The application is filed electronically through ELSTER, together with the Sondervorauszahlung calculation for monthly filers. The timing that matters:

• Monthly filers: apply by 10 February of the year you want it to take effect.
• Quarterly filers: apply by the Q1 deadline, 10 April.
• New registrations: you can request the extension as part of setting up your German VAT registration, rather than waiting for the next February window.

Is it worth it for a foreign seller?

For most foreign companies, yes. The single most common cause of German late-filing surcharges (Verspätungszuschlag) is missing the 10th-of-month deadline, and cross-border bookkeeping, marketplace report timing, and currency reconciliation all eat into that tight window. An extra month is a genuine safety margin, not a luxury.

The only reason to skip it is if you strongly prefer not to front the Sondervorauszahlung cash for the year, and even then, quarterly filers avoid it entirely. For a business already stretched by month-end close, the trade is almost always worth making.

How Vaytax handles the extension

If you already hold a Dauerfristverlängerung, you tell us once at signup, and every deadline shown in your Vaytax account, in the filing wizard, on the dashboard, and in your reminder emails, shifts by a month automatically. You never have to track two sets of dates or mentally add a month. If you want to set an extension up, we arrange it through your licensed German tax advisor as part of the service. Either way, the full 2026 calendar with and without the extension is in our printable VAT deadline calendar.

Frequently asked questions

What is a Dauerfristverlängerung?

It is a permanent one-month extension of your German VAT filing and payment deadlines (§ 46 UStDV). Instead of the 10th of the following month, your monthly Umsatzsteuer-Voranmeldung and its payment are due the 10th of the month after that. It renews automatically each year once granted.

What is the Sondervorauszahlung and do I have to pay it?

Monthly filers pay a special advance payment (Sondervorauszahlung, § 47 UStDV) to receive the extension: one eleventh of the previous year's total advance payments, due 10 February. It is not an extra cost, it is credited back against your December return. Quarterly filers get the extension without any Sondervorauszahlung.

When do I apply for it?

For monthly filers, by 10 February of the year you want it to apply; for quarterly filers, by the Q1 deadline (10 April). New registrations can request it as part of registering. It is filed electronically via ELSTER along with the Sondervorauszahlung calculation.

Is the extension worth it for a foreign seller?

For most foreign sellers, yes. The tight 10th-of-month deadline is the most common cause of late-filing surcharges, and the extra month is a real buffer against the delays of cross-border bookkeeping. The only trade-off is the Sondervorauszahlung cash-flow for monthly filers, and even that is credited back.

Does Vaytax handle the deadline extension?

Yes. If you already hold a Dauerfristverlängerung, tell us at signup and every deadline in your account shifts by a month automatically, so you never track two sets of dates. If you want to set one up, we arrange it with your licensed tax advisor.
