Taxdoo no longer files VAT returns. The company discontinued its EU VAT compliance and accounting-export services on 30 April 2026 to focus on accounting software. If you moved to a new provider in spring, this guide remains the comparison it always was. If you never switched, your German filings have been stopped since the May 2026 period, and the consequences grow every month: start with what is happening to your unfiled returns below.

Still Haven’t Replaced Taxdoo? Here Is What Is Happening to Your Filings

Taxdoo’s last filing cycle was the April 2026 return. If nobody took over after that, every German VAT period from May 2026 onward has gone unfiled. By August 2026 that typically means two or three missing monthly returns, or a missing second quarter for quarterly filers. These returns do not lapse quietly. Two things happen on the Finanzamt’s side:

1. Late-filing surcharges accrue per return, per month. The Finanzamt can impose a late-filing surcharge (Verspätungszuschlag) under § 152 AO of 0.25% of the assessed VAT for every started month of delay, with a minimum of €25 per started month, for each unfiled return. There is no percentage cap; the only ceiling is an absolute €25,000. The minimums alone add up: €25 for each started month, for each return, so a seller several returns behind accumulates surcharges on all of them in parallel, before the actual tax and interest.

2. The Finanzamt does not wait for you to file. When returns stay missing, it issues an estimated assessment (Schätzbescheid), and the estimate is deliberately set high, because it is meant to be worse than filing honestly. Once the objection window closes, that assessment is legally binding whether or not the figure resembles what you actually owed, and surcharges and interest are added on top. Payment reminders (Mahnung) and formal hearing notices (Anhörung) tend to arrive in the same stretch of post.

What to do this week

1. Stop the clock. Surcharges grow with every started month, so the cheapest day to fix this is today. Filing the real figures also replaces an estimated assessment that has not yet become final.
2. Have the missed months filed, not just the next one. Vaytax takes over your German VAT filings at €99/month and files the unfiled past periods at €99 per past return: you pick the first period we need to file, the checkout names the exact returns before you pay, and one late quarter counts as one return, not three months. Any surcharges the Finanzamt issues for the late periods are independent of our fees; filing quickly is what keeps them small. Our provider-switch guide walks through the takeover (Vollmacht handover, no re-registration).
3. If Finanzamt letters have already arrived, decode them first. Upload any letter, whether an estimated assessment (Schätzbescheid), payment reminder (Mahnung) or hearing notice (Anhörung), on our Finanzamt letter page for a free instant English read, no signup. If you want it handled, you get a fixed-price quote, from €200 net.
4. If Taxdoo also filed your OSS returns: for sellers established outside the EU that file the One-Stop-Shop (OSS) through Germany, Vaytax offers standalone OSS filing at €300 one-time registration plus €200 per quarter via /oss-start, without moving your other filings. EU-established sellers file OSS in their home member state, so that part is not something we can take over.

What Happened: Taxdoo’s VAT Exit Explained

Taxdoo announced in December 2025 that it would discontinue VAT compliance and accounting-export services, and the shutdown took effect on 30 April 2026, redirecting the business toward accounting software. The company has not published a detailed strategic explanation, but the practical effect is straightforward: since May 2026, Taxdoo does not file your monthly VAT return (UStVA), does not maintain your accounting exports, and does not handle Finanzamt correspondence on your behalf.

When this guide was first published in April 2026, the advice was to line up a new provider within 1–3 weeks. That window has closed. Taxdoo filed its last returns for the April 2026 period; every period since is either with your new provider or nowhere. If it is nowhere, the unfiled-returns section above covers what that costs and how to catch up.

The Steuernummer itself is not at risk. It belongs to your company, not to Taxdoo. The migration is a power-of-attorney handover, not a re-registration. But it does need to happen on a calendar.

Provider-by-Provider Breakdown

Migration Playbook: Taxdoo to a New Provider

1. Sign a Mandatsvereinbarung with the incoming tax advisor this week. The new provider needs a signed engagement letter and Vollmacht (power of attorney) before they can communicate with the Finanzamt on your behalf. Vaytax can have this paperwork in your inbox within 24 hours of registration.
2. Request your full Taxdoo handover pack. Ask Taxdoo for: (a) the last 12 months of UStVA and ZM filings as PDFs, (b) the latest annual VAT declaration if filed, (c) an accounting export covering 1 January 2026 to handover date, (d) any open Finanzamt correspondence, (e) confirmation that they have terminated their Vollmacht. Start this request now: the compliance team wound down in April 2026, so responses can take longer than they used to.
3. Confirm which periods are still open. Taxdoo’s last filing cycle was the April 2026 return; your new tax advisor takes over every period from May 2026 onward, including any that were never filed. Make sure the handover does not leave a month uncovered. If you have a filing extension (Dauerfristverlängerung) in place, confirm the deposit and filing schedule transfers cleanly.
4. Update your transaction-data flow. Whatever ingest you used to feed Taxdoo (Amazon reports, Shopify exports, manual XLSX, JTL/Billbee feeds) needs to redirect to the new provider. With Vaytax, monthly turnover uploads happen via the dashboard or direct email, no API contract change required.
5. File the new Vollmacht with the Finanzamt. Your new tax advisor handles this. Once the Finanzamt processes the Vollmachts­wechsel, all future correspondence and filing access flows through the new provider. There is no re-registration step.
6. Verify the first filing landed. After your new provider files the first return, request the Finanzamt confirmation receipt (Übermittlungsprotokoll) and the accounting export. Both should match what you saw under Taxdoo, this is your sanity check that the migration was clean.

Five Questions to Ask Any Replacement Provider

1. “Is a licensed German tax advisor named on my filings, and are they a member of a Steuerberaterkammer?”, The answer should be a name and a Kammer. Vague references to “our partner network” are a yellow flag.
2. “What is the all-in monthly cost for Germany, in writing, with no per-transaction surcharges?”, Get it in the engagement letter. The Taxdoo migration is the moment competitors will quote attractively then surface fees later.
3. “Is Finanzamt correspondence included, and how do you handle audits or queries?”, This is where multi-country platforms tend to bill separately at €150–200/hour. Confirm.
4. “What is the cancellation notice period?”, Watch for 12-month auto-renewal clauses. Vaytax cancels at the end of the following month with no auto-renewal.
5. “Can you take over my Vollmacht, file the next return on time, and also file the months missed since Taxdoo’s exit?”, If they can’t commit to a date for both, they don’t have capacity. Move on.

Frequently Asked Questions

Why did Taxdoo exit VAT compliance?

Taxdoo announced in December 2025 that it would shift focus to accounting software, and it discontinued its EU VAT compliance and accounting-export services on 30 April 2026. Existing customers were notified and directed to find a replacement provider for their VAT filings. The strategic reasoning has not been detailed publicly, but the practical effect is the same: any business that filed German VAT through Taxdoo has needed a new provider since the May 2026 reporting period.

What are the best Taxdoo alternatives for German VAT?

For German VAT compliance, Vaytax is typically the best value: a licensed tax advisor files with the Finanzamt at €1,499/year all-in for new registrations (registration included), or a fixed €99/month with an existing German Steuernummer, with no per-transaction surcharges. Multi-country platforms such as hellotax, countX, AVASK and Taxually also file German VAT as part of wider EU coverage; the cost of Germany alone there is typically higher and pricing is often quote-based, so compare written all-in quotes before signing. The right choice depends on whether Germany is your primary market or one of several.

How long does it take to migrate from Taxdoo to a new VAT provider?

For Germany alone, a clean migration takes 1–3 weeks. The Steuernummer stays with your company, not with Taxdoo, so the new tax advisor simply needs a fresh Vollmacht and your prior filings. The bottleneck is usually getting Taxdoo to release historical filings and accounting exports, start that request as soon as possible.

Will my German Steuernummer change when I switch from Taxdoo?

No. The Steuernummer (and your USt-IdNr.) is tied to your company entity, not to your provider. Switching VAT compliance providers does not require any change at the Finanzamt, you simply revoke Taxdoo’s power of attorney and grant a new one to your incoming tax advisor. There is no gap in your tax registration. See our Steuernummer vs USt-ID guide if you need a refresher on which number is which.

What documents do I need to migrate from Taxdoo?

Five things: (1) your last 12 months of VAT filings (UStVA + ZM if applicable), (2) any open Finanzamt correspondence, (3) the most recent annual VAT declaration if filed, (4) an accounting export of your transactions for the current year, and (5) confirmation from Taxdoo that they have terminated their Vollmacht with the Finanzamt. Your incoming tax advisor will then file a new Vollmacht and continue from the next open reporting period.

Can I switch mid-year without missing a filing deadline?

Yes. Switching German VAT providers mid-year is routine: the incoming tax advisor takes over from the next open period, and your Steuernummer does not change. For former Taxdoo customers the question has shifted: Taxdoo’s last filing cycle was the April 2026 return, so any period from May 2026 onward that nobody filed is now overdue. Each unfiled return can accrue a late-filing surcharge (Verspätungszuschlag) of 0.25% of the assessed VAT per started month, minimum €25 per started month, with no percentage cap. Vaytax files the missed months as part of the takeover at €99 per past return. See our 2026 deadline calendar for the full schedule.

I never replaced Taxdoo and have unfiled German returns. What happens now?

Unfiled months do not go away. The Finanzamt can impose a late-filing surcharge (Verspätungszuschlag) of 0.25% of the assessed VAT per started month of delay, minimum €25 per started month, for each unfiled return, with no percentage cap (the only ceiling is an absolute €25,000). If returns stay missing, the Finanzamt eventually issues an estimated assessment (Schätzbescheid) with a deliberately high estimate that becomes legally binding once the objection window closes. The fix is to file the real returns: Vaytax takes over your German VAT filings at €99/month and files the missed months at €99 per past return, with the exact returns named at checkout before you pay. The section at the top of this guide and our provider-switch guide walk through it, and a free English read of any Finanzamt letter is available if post has already arrived.
