How much to set aside each month for taxes?

Tax depends on income, commune, marital status and deductions, so there is no percentage that fits everyone, and none of the official sources consulted gives one, neither the FTA nor the tax offices of four cantons. The starting point is the tax of the year, taken from your last final bill if your situation has not changed or estimated with the FTA calculator, divided by 12. This page is general information, not tax advice.

Budgetberatung Schweiz treats taxes as a fixed item in every budget: when the amounts are set aside every month or paid by standing order to the tax office, there are usually no nasty surprises. That the 13th salary will cover them is, it says, true only in a few cases. In the canton of Vaud, the cantonal and communal income and wealth tax is already paid in twelve monthly instalments.

As context only: in 2023 an average household (2.07 persons) paid CHF 1'245 a month in taxes, the main item of compulsory spending (FSO). It is the average of all households, not a target.

Why does the tax bill come later?

Because the tax of a year can only be calculated once the year is over: the canton knows your income and deductions when you file your return and are assessed. Until then it bills an estimate, and the final statement follows.

The estimate takes the form of a provisional bill or instalments, in general based on the last assessment or return. The final bill follows the assessment: in Aargau what you overpaid is refunded and what you underpaid is claimed; in Vaud the final statement arrives in principle within twelve months of filing the return, and any balance is payable within 30 days. If your situation changes, the estimate does not know it: Aargau and Vaud describe how to ask for a change, and Budgetberatung Schweiz suggests comparing the taxable income assumed in the provisional bill with the one you expect and, if they differ, having it adjusted. Vaud points out, for example, that the 2026 instalments do not take into account the 13th AHV pension, paid for the first time in December 2026, and urges AHV recipients to ask for a change.

The direct federal tax has its own dates: in Aargau it is as a rule billed in the following year, with a provisional bill at the end of February payable by 31 March; in Zurich it is billed in March for the previous year, with the same deadline; in Vaud it is in general included in the twelve instalments.

How do you estimate the amount with the FTA tax calculator?

The tax calculator of the Federal Tax Administration estimates income and wealth tax for your commune. The calculation is neither binding nor guaranteed, and your actual assessment may differ (FTA, May 2026).

1. Open the tax calculator, keep “Income and wealth tax” and choose the tax year.
2. Enter your postcode or place: the calculation uses the taxes of your commune.
3. Choose marital status, age, children and religion: the FTA uses them for the tax rate, the occupational pension deduction, child deductions and church tax.
4. Choose the type of income and enter the yearly amount in CHF: “Gross income” (employees), “Net income” (self-employed), “Pension income” (AHV and pension fund), “Other income”, or “Taxable income” if you start from your last assessment; in that case only tax rates and multipliers are applied, and the taxable income for the direct federal tax is asked separately.
5. If you want, switch on “Detailed calculation: add deductions”; otherwise only the flat-rate deductions apply, those that need no proof.
6. Enter your net worth and press “Calculate”.
7. Read the expected total burden in francs and as a percentage of income, split into cantonal, communal, church, federal and personal tax, and divide it by 12.

Compare the result with your last bill: if the gap is large, check your entries or ask the tax office of your canton. Budgetberatung Schweiz notes that many cantons have their own calculator and that the result, though not exact to the franc, shows the direction. How taxes differ from canton to canton is explained in the guide to the cost of living by canton.

How do instalments, due dates and interest work in the cantons?

The rates and dates in the table apply to 2026, and other cantons have their own rules: your bill and the page of your tax office decide. Zurich and Vaud also have a compensatory interest between the general due date and the final statement (0.75% and 0.125% in 2026). For the direct federal tax the 2026 rates are 4.0% late and 0.0% on early payments, set every year by the Federal Department of Finance (page of the canton of Zurich, in German).

Withholding tax: who pays it?

According to the FTA, withholding tax (tax at source) is deducted directly from the income of two groups of employees: people with tax residence in Switzerland who have no settlement permit (permit C), and people without tax residence in Switzerland, such as cross-border commuters. The employer withholds it from the wage and passes it on to the competent cantonal tax administration, and the rate depends on the canton. So on that wage the tax is already withheld every time you are paid. When tax at source ends because of a change of residence status, ordinary taxation starts, and Budgetberatung Schweiz warns that many are not prepared: no standing order, no provisions, and by the time the bill arrives the money is already spent.

How to put taxes into your budget from today

The first step is an estimate: the yearly tax from your last bill or the FTA calculator, divided by 12. Then enter the amount among your fixed costs (monthly fixed costs, fixed-costs calculator) and note your canton’s dates in the deadlines calendar, to compare them with what you will have set aside by then. The whole budget is explained in the guide on how to make a budget.
