What is Mehrwertsteuer Saldosteuersatz (VAT Flat-Rate Method)?
The Saldosteuersatz is an optional simplified VAT accounting method in Switzerland where small businesses apply a sector-specific flat rate to their gross revenue instead of tracking individual input and output MWST. The flat rate is lower than the standard MWST rate and approximates the net VAT liability after typical input tax deductions for that industry.
Current Rate (2025)
Available for businesses with taxable turnover under CHF 5,000,000 and net MWST liability under CHF 100,000. Flat rates range from 0.1% to 6.5% depending on industry sector.
Example
A freelance IT consultant with CHF 300,000 annual turnover uses the Saldosteuersatz method. Their sector rate is 5.9% of gross revenue. They remit CHF 17,700 MWST to the ESTV semi-annually — significantly less bookkeeping than tracking every input and output invoice.
How Mehrwertsteuer Saldosteuersatz (VAT Flat-Rate Method) works in Switzerland
The Saldosteuersatz (sometimes called Pauschalsteuersatz in certain contexts) is one of Switzerland's most business-friendly VAT simplifications, available to qualifying small businesses.\n\n**How it works**\nInstead of the normal 'effective' method (recording every input and output VAT separately, net the difference, remit), under Saldosteuersatz the business:\n1. Applies its sector's flat rate to total gross revenue (including MWST charged to customers)\n2. Remits that calculated amount to the ESTV semi-annually\n3. Does NOT track individual input tax receipts for VAT purposes\n\n**Sector rates**\nThe ESTV publishes a table of rates covering several dozen industries. Examples as of 2025:\n- Retail trade: 0.6%–2.1%\n- Restaurant/catering: 5.1%\n- IT consulting: 5.9%\n- Architecture/engineering: 6.5%\n- Construction: 2.9%\n- Accountancy/fiduciary: 6.0%\n\n**Advantages**\nDramatically reduces bookkeeping. No need to reconcile input tax invoices. No risk of disallowed input tax on mixed-use purchases. Semi-annual filing rather than quarterly.\n\n**Disadvantages**\nIf your actual input tax is high (e.g. you import expensive equipment regularly), the effective method may result in lower net MWST payments. Cannot use the effective method in the same year — you must switch formally and the switch is binding for one year. When you exceed the CHF 5m threshold, you automatically switch to the effective method.\n\n**Switching**\nApplication to use Saldosteuersatz is made to the ESTV at any time but takes effect from the beginning of a tax period. Changes between methods must be notified to the ESTV.
