VAT Method Switch in Switzerland: Timing and Conditions for SMEs

Choosing your VAT accounting method is not a one-time decision for life. Many Swiss SMEs discover only after several years that they're using the wrong method — and end up paying too much VAT or missing input tax deductions they could claim. This article explains the conditions for switching methods, the applicable deadlines, and how to identify the right timing.

Quick overview: Two methods, two logics

Every VAT-liable business in Switzerland accounts for VAT either using the actual method or the balance tax method. The actual method records all revenue and all input tax amounts separately — it's more precise but more labour-intensive. The balance tax method simplifies accounting considerably, as a sector-specific rate (typically between 0.1% and 6.8%) is applied to gross revenue. In return, input tax documentation is largely eliminated.

Both methods lead to different calculations — depending on your sector, cost structure, and investment level. This is precisely why switching can make sense.

Who is allowed to switch?

Not every business can freely switch between methods. The Federal Tax Administration (FTA) links a switch to the balance tax method to these conditions:

• Annual turnover under CHF 5,005 million (taxable revenue)
• Annual tax liability under CHF 103,000 (calculated using the balance tax method)
• The business must have been accounting using the actual method for at least one full tax year before switching to the balance tax method is permitted

When switching back to the actual method, comparable turnover limits don't apply — in principle it's possible at any time, but it's also subject to strict deadlines.

Deadlines: When must the request be submitted?

This is where most mistakes happen. A method switch must be notified to the FTA in writing before the start of the tax period for which it should apply.

Desired switch effective	Request must be received by
1 January 2027	31 December 2026
1 January 2028	31 December 2027

A tax period corresponds to the calendar year. If you submit your request on 15 January, the earliest you can switch is 1 January of the following year. The FTA does not accept retroactive switches.

Minimum binding period: After switching to the balance tax method, you are bound to that method for at least one full calendar year. After switching to the actual method, there is no legally prescribed minimum binding period, but in practice a binding period of at least one year is also recommended for planning reasons.

Typical scenarios when a switch makes sense

Switch from actual to balance tax

This step typically pays off when:

• Your business has few deductible input tax investments (e.g. pure service businesses like consulting, coaching, graphic design)
• Accounting costs at your tax advisor consume a noticeable portion of the tax benefit from the actual method
• Your sector's balance tax rate is significantly lower than the effective VAT rate on your revenue (e.g. 8.1% on services, but balance tax rate of 5.9%)

Example calculation: A web designer with CHF 180,000 annual revenue and minimal input tax pays 8.1% VAT minus minimal input tax — roughly CHF 13,500. With a balance tax rate of, say, 5.9%, that would be CHF 10,620. Difference: nearly CHF 2,900 per year.

Switch from balance tax to actual

The benefit outweighs the complexity when:

• Larger investments are planned (machinery, vehicles, IT infrastructure) and input tax on those purchases is high
• The effective VAT rate on your revenue is lower than the balance tax rate (e.g. services at the reduced rate of 2.6% or special rate of 3.8% for accommodation)
• Your business regularly generates input tax credits and receives refunds from the FTA

When investments change the equation

An often underestimated scenario: A business plans a major purchase — say a vehicle for CHF 60,000 plus CHF 4,860 VAT. Under the balance tax method, this input tax largely expires. Under the actual method, it can be fully or partially reclaimed. For an investment year like this, the switch alone could be worth several thousand francs because of this purchase.

What to do concretely when switching

1. Perform the calculation: Compare the revenue of the last 12 months against input tax amounts. Your tax advisor can typically prepare this comparison quickly.
2. Determine your sector's balance tax rate: The FTA maintains a list of all approved balance tax rates by sector. Some businesses qualify for two different rates if they conduct different activities. A structured comparison is available in the article on VAT balance tax rates by industry.
3. Submit request to FTA: Written notification by post or via the FTA online portal (VAT accounting online). No special form needed — a simple letter with your UID, desired switch date, and target method is sufficient.
4. Adjust accounting: Chart of accounts, posting logic, and invoice templates must be adapted to the new method. With the balance tax method, separate input tax posting is eliminated.
5. Issue invoices correctly: The VAT shown on the invoice always corresponds to the statutory tax rate (e.g. 8.1%), regardless of which accounting method you use internally. When creating your invoices with SnapBill, the correct rate is automatically applied.

Common misunderstandings

"The switch takes effect immediately": No — it always takes effect at the start of the next tax period.

"I can switch every year": Theoretically possible, but after a switch to the balance tax method, the one-year binding period applies. Frequent switches are also a red flag for the FTA.

"I can choose any balance tax rate": No — the FTA sets it and it's sector-specific. You request it; the FTA approves it.

At a glance

• Method switch always in writing by 31 December of the prior year
• Switch to balance tax method only available with turnover under CHF 5,005 million and tax liability under CHF 103,000
• Minimum binding period after switch to balance tax method: one calendar year
• Worth switching to balance tax: few investments, high administrative burden, low sector rate
• Worth switching to actual method: major investments, revenue at lower rates (2.6% / 3.8%)
• VAT rate shown on invoices always remains the statutory rate — regardless of your accounting method
