Swiss VAT Deregistration: Deadlines and Final Return

Before deregistering from Swiss VAT (MWST), establish whether you are continuing your business with lower turnover or ending business activity altogether. This determines the removal date and notification deadline. Deregistration does not replace your final VAT return or the duty to retain records.

When you can deregister: three scenarios

Scenario 1: Turnover stays below CHF 100,000

If relevant turnover falls below the threshold and is expected to remain below it in the following tax period, removal is possible no earlier than the end of the tax period in which turnover fell below the threshold. The Federal Tax Administration (FTA, ESTV) requires notification within 60 days after that period ends, no later than the end of February of the following year.

The relevant figure is generally worldwide turnover from supplies not exempt under Article 21(2) MWSTG, calculated on agreed consideration excluding VAT. CHF 60,000 in Swiss consulting fees plus CHF 50,000 in comparable fees from German clients totals CHF 110,000. No Swiss VAT on a foreign supply does not automatically exclude its turnover from the threshold. Assess special statutory exemptions separately.

Fictional example — Sandra: A graphic designer has CHF 82,000 of relevant turnover in 2026 and also expects less than CHF 100,000 in 2027. She applies for removal effective 31 December 2026 and notifies the FTA on time. She keeps evidence of the forecast and actual annual turnover. Lower turnover alone does not automatically remove her from the register.

Scenario 2: Business closure, liquidation or retirement

For a Swiss business, VAT liability ends when business activity ends; where assets are liquidated, it ends only on completion of liquidation. Under Article 66(2) MWSTG, written deregistration must be submitted within 30 days after activity ends, but no later than completion of liquidation. Retirement alone is not enough if the business continues.

Scenario 3: Giving up self-employment for a salaried job

Starting a salaried job does not by itself end VAT liability. If you continue the business part-time, assess its turnover and activities as before. If you close it completely, the business-closure rules apply. Any notification to the AHV compensation office is separate.

Notification deadlines and the final return are separate

If you want to leave because turnover has declined but do not notify the FTA on time, Article 14(5) MWSTG treats this as waiving the exemption. You remain liable and must not simply stop filing or paying.

For voluntary registration, Article 11 MWSTG requires at least one tax period, not a general three-year commitment. Do not confuse this with the minimum periods for switching between the effective and net tax rate methods.

The final return has its own deadline: under Article 71(2) MWSTG, the 60 days run from the end of VAT liability. If you stop during the year, do not automatically wait until the next year-end. Clarify the exact closing date and payment with the FTA.

Step by step: deregistering with the FTA

1. Clarify the reason and cut-off date. Start with the official FTA deregistration page and choose the relevant form. Contact the VAT collection division for transfers, mergers or unclear liquidation cases.
2. Prepare the information. Have your VAT number, contact details, turnover calculation, requested removal date, outstanding consideration and retained assets ready.
3. Submit and keep the evidence. Save the acknowledgement, then the decision stating the removal date. Do not assume a guaranteed processing time.
4. Reconcile the final return and invoice templates. Allocate supplies, receivables, input tax and adjustments to the correct period.
5. Check other bodies separately. Deregistering from VAT does not automatically deal with the commercial register, compensation office, contracts or business archive.

Invoices, input tax and receivables after deregistration

New supplies after removal: without registration, you generally must no longer show VAT on them. Check templates, recurring invoices and tax-related details. A UID can remain as a business identifier; it does not prove continuing VAT registration.

Earlier supplies and outstanding receivables: the invoice date alone does not decide whether the supply belongs before or after removal. Receivables already declared on agreed consideration must not be taxed again when payment arrives. Under received consideration, account for outstanding receivables on closure. For net tax rates, Article 82 MWSTV expressly covers work in progress and, under received consideration, receivables. Have unbilled work and later corrections reviewed separately.

No general input tax deduction after exit: review retained assets and earlier deductions. Under the effective method, the end of liability can trigger an own-use adjustment under Article 31 MWSTG, generally based on the current value of goods or services already used. Buying just before deregistration does not automatically secure a lasting full deduction. The closing rules for net tax rates are not the same as those for the effective method.

Preparing the final VAT return

In particular, prepare:

• Turnover and supplies not yet accounted for up to the cut-off date, separated by tax treatment.
• Outstanding receivables and evidence of which VAT has already been declared.
• Eligible input tax or approved net tax rates, together with required adjustments.
• An inventory of retained goods and services with earlier input tax deductions and current-value calculations where relevant.
• Reconciliation with earlier returns, submission confirmation and proof of payment.

Missing returns can lead to an estimated assessment and further consequences. Late payments can trigger interest. An automatic flat or turnover-dependent late-filing fee is not a reliable general rule.

Common deregistration mistakes

Showing VAT without entitlement: the tax shown may be owed under Article 27 MWSTG. But it is not necessarily irretrievably lost: the Act provides for invoice correction or credible proof that no tax loss arose for the Confederation.

Fictional calculation: 8.1% is mistakenly shown on CHF 4,500 net, producing CHF 364.50 VAT. Check the correction with reference to the original invoice and coordinate it with the recipient. Changing a template alone does not correct an invoice already sent.

Declaring receivables twice: reconcile closure with the accounting basis previously used. Both “tax all later receipts again” and “everything after removal is tax-free” are wrong.

Checklist for sole proprietorships

• Establish whether business activity continues or ends
• Document relevant worldwide turnover and the forecast
• Determine the cut-off date and applicable 30- or 60-day notification deadline
• Note the final return deadline from the end of VAT liability
• Retain the application and removal confirmation
• Reconcile receivables, work in progress and assets
• Update invoice templates for new supplies
• Save records and exports for retention
• Check other registers and insurance bodies separately

Conclusion: deregistration is a process with cut-off dates

The essentials are the correct reason, timely notification and a traceable closing process.

For unclear closing cases, contact the FTA or a qualified Swiss fiduciary.
