On 22 September 2026, the Swiss Federal Tax Administration (FTA) released its annual circular on the compensation for cold progression and the applicable interest rates for direct federal tax for the upcoming 2027 tax year. Cold progression, often referred to as bracket creep, occurs when inflation pushes nominal incomes into higher tax brackets without a corresponding increase in real purchasing power. Since the last adjustment, the Swiss consumer price index has risen by 0.47 percent, triggering a mandatory indexation of the direct federal tax tariff and deduction amounts under Article 38 of the Federal Act on Direct Federal Tax (DBG). The circular details the precise percentage adjustments for each tariff bracket, ensuring that the progressive tax structure maintains its real value. The adjustments apply to all categories of taxpayers, including single individuals, married couples, and single parents, and cover both the basic deduction and the child deduction. The new tariffs will be used for provisional tax assessments in 2027 and final assessments in 2028.
Key Takeaways
- Comprehensive Tariff Indexation: The 0.47 percent upward adjustment applies to all direct federal tax brackets and deductions. For a single taxpayer, the basic deduction increases from CHF 14,500 to CHF 14,568, while the top marginal rate threshold shifts proportionally. This prevents an estimated CHF 120 million in additional federal tax revenue that would have arisen purely from inflation.
- Interest Rate Stability: The late payment and refund interest rate remains at 4.0 percent, and the compensation interest for voluntary advance payments stays at 0.0 percent for 2027. This stability simplifies cash flow planning for corporations and individuals making voluntary prepayments or facing tax assessments.
- Automatic Cantonal Implementation: Cantonal tax authorities will automatically apply the revised tariffs and deductions in their 2027 tax assessment software. Taxpayers need not file separate requests; the adjustments will be reflected in provisional and final tax bills issued from 2028 onward.
