Why foreign services change your VAT compliance
Cloud software, consulting, digital marketing, hosting, SaaS licences, translations, or legal reviews from providers based outside Switzerland are everyday costs for SMEs. Foreign invoices often show net amounts, with no Swiss VAT and sometimes no mention of the supplier’s local tax either.
In many cases that does not mean the transaction is outside the scope of VAT: the Federal Act on Value Added Tax (VAT Act, RS 641.20) places on the Swiss taxable recipient the obligation to calculate and declare tax on services received from abroad. This is reverse charge or, in official terms, acquisition tax (Art. 45 VAT Act).
Self-assessment is not a mere accounting formality: it must appear on the periodic VAT return and match your ledger entries. Systematic errors—omissions, wrong rates, or missing input tax deduction—are among the signals the Federal Tax Administration (FTA) checks when auditing VAT-registered businesses.
When reverse charge applies to foreign services
The starting point is the place of supply (Art. 8 para. 1 VAT Act). For services supplied to a taxable person with seat or domicile in Switzerland, the recipient principle usually applies: the place is Switzerland. If the supplier is not registered in the Swiss VAT register (typical for foreign providers without a permanent establishment locally), tax is not charged on the foreign document: the Swiss recipient self-assesses via acquisition tax.
| Situation | Who charges VAT | Practical note |
|---|---|---|
| B2B service from foreign supplier to VAT-registered SME in CH | Recipient (reverse charge) | Foreign invoice without CH VAT; self-assess on the return |
| Foreign supplier with branch/permanent establishment registered for VAT in CH | Swiss supplier (as a rule) | Swiss VAT on invoice; no self-assessment on your side |
| Supply excluded or exempt without right to deduct | Varies | Check rate and deduction entitlement before posting |
| Import of goods (physical merchandise) | Not reverse charge for “services” | VAT on import / customs procedures—do not confuse with intangible services |
| Non-taxable business or special scheme without full deduction | May need to self-assess without full offset | Non-registered recipients: obligation only above CHF 10,000 p.a. of similar supplies (Art. 45 para. 2 VAT Act); impact on effective cost |
The CHF 100,000 turnover threshold for mandatory registration (Art. 10 VAT Act) does not exempt you from self-assessment once you are registered. VAT-registered small businesses must still treat every relevant foreign invoice correctly in the accounting period.
Rates and classification of the supply
Standard rate (8.1%)
Applies to most services: consulting, IT, project management, design, data analytics, remote maintenance, non-school training, etc. The most common mistake is applying a reduced rate without analysing the economic content of the invoice.
Document internally why you chose the rate (description of supply, reference to the tariff) to support your position in an audit.
Reduced and special rates
Accommodation in hotels is taxed at 3.8%; other categories fall under the 2.6% reduced rate (e.g. certain cultural goods or food products, if the nature of the supply allows). Restaurant meals are usually standard rate. A foreign supplier’s “mixed” subscription should be split where possible; when in doubt, your tax adviser helps avoid multi-year corrections.
Convert the amount to Swiss francs at the exchange rate for the relevant day (usually invoice or supply date, per your consistent accounting practice).
Correct bookkeeping in the general ledger and VAT account
Reverse charge creates two mirror VAT entries for those with full deduction: tax due (outflow) and deductible input tax (inflow) on the same tax base. Cash flow may show no payment to the FTA if offset is full, but the return must still report both lines.
Recording the expense: debit expense or fixed asset account (if capital) net, plus self-assessed VAT if not immediately offset in deduction, or use dedicated VAT accounts under the Swiss chart of accounts (e.g. VAT due on foreign purchases / deductible input VAT).
VAT return: enter the taxable amount and tax in the fields for acquisition tax (typically 381 and 382 under the effective method) and the corresponding prior-period input tax deduction, if allowed. Totals must tie to the period’s account statement.
Software such as Accountex: defining a posting reason or document type “Foreign service / reverse charge” cuts manual errors, links the PDF invoice to the entry, and eases pre-quarter-end reconciliation.
Simplified example (8.1% rate, full deduction)
Foreign consulting invoice EUR 10,000, FX CHF 9,500 taxable. Self-assessed VAT: CHF 769.50. Typical entries: expense CHF 9,500; VAT due CHF 769.50; deductible input VAT CHF 769.50. Period VAT balance: neutral; accounting cost: CHF 9,500. Without the pair of VAT postings, the return is understated in the FTA’s view even if the balance sheet cost looks “correct”.
Documentation and audit trail
- •Keep the original invoice, proof of payment, and any contract describing the supply and place of use in Switzerland.
- •Check that the supplier has not wrongly charged Swiss VAT without being registered: if so, request a correction; do not duplicate the tax.
- •Note the foreign supplier’s UID only if shown; for self-assessment what matters is your registration and the nature of the service, not the absence of a foreign UID.
- •For foreign credit notes, reverse taxable amount and self-assessed VAT in the period of the note.
- •Align procurement and accounting: whoever approves spend should know that “no VAT” invoices from abroad are not automatically exempt.
Common errors that draw FTA attention
In audits, the FTA cross-checks VAT returns, analytical accounts, and foreign-currency bank statements. On foreign services, the same non-compliance patterns recur:
Complete omission of self-assessment
Foreign invoices are posted to expense only with no VAT entry. Result: understated tax base, possible default interest and penalties for incomplete returns.
Tax due only, no deduction
VAT is self-assessed but the allowed deduction is omitted, artificially inflating tax payable and distorting declared liquidity.
Wrong rate or period
Booking in the wrong quarter, using 2.6% on standard services, or failing to adjust after a rate change (e.g. standard rate updated to 8.1% from 1 January 2024).
Confusion with reverse charge on buildings or goods
Art. 45 VAT Act also covers other cases (e.g. certain property purchases or energy supplies). Applying the same accounting logic without distinguishing the category creates inconsistencies on the VAT return.
Missing integration in period close
Services received in late December booked in January without correcting VAT for the prior period; misalignment between economic accrual and the return.
Operational checklist for SMEs
| Step | Action |
|---|---|
| 1 | Identify foreign supplier and legitimate absence of Swiss VAT on the invoice |
| 2 | Classify the supply and applicable VAT rate |
| 3 | Convert to CHF and calculate self-assessed VAT |
| 4 | Post expense + VAT due + deductible input VAT (if entitled) |
| 5 | Report amounts on the VAT return for the accrual period (acquisition tax) |
| 6 | Archive documents and internal note on the rate chosen |
| 7 | At quarter-end, reconcile total foreign services with the VAT account |
Building it into day-to-day management
Reverse charge on foreign services is not just for multinationals: it affects every SME using digital tools, consultants, or global networks. Treating it as routine bookkeeping—not an exception—keeps the VAT account and financial statements aligned and reduces the risk of retroactive adjustments.
A digital workflow that flags foreign invoices automatically, suggests self-assessment, and links the periodic return to ledger entries frees the owner and tax adviser for targeted checks instead of emergency fixes before an FTA audit.
