Swiss tax return: Vaud 2026 guide

Context

In brief

• Three levels: federal, cantonal and municipal
• Vaud has its own law and multiplier
• Deadlines are set at cantonal level
• The online procedure guides submission

Key facts

• Tax system → direct federal, cantonal and municipal tax
• AFC/ESTV → direct federal tax and VAT
• Cantons → their own law and multiplier
• Municipalities → multiplier on the cantonal component

In Switzerland, filing a tax return starts with a precise distinction: taxation is structured at three levels, namely direct federal tax, cantonal tax and municipal tax. For the canton of Vaud, the 2026 guide must therefore be read by separating the federal component from those managed by the canton and municipality.

Three levels, three areas of responsibility

Each canton has its own law and its own multiplier. The municipality applies its multiplier to the cantonal component. This structure makes it necessary to check the federal, cantonal and municipal instructions separately before completing the tax return.

AFC/ESTV is the authority responsible for direct federal tax and VAT. Cantonal administrations, on the other hand, manage cantonal and municipal taxes. This distinction is also useful for the canton of Vaud: a question about the federal component should not be confused with an issue relating to cantonal law or the municipal multiplier.

The calendar also follows a cantonal logic. For the tax return relating to Vaud, it is necessary to follow the scheduled cantonal deadline and use the online procedure indicated by the competent administration. There is no single national deadline to replace the canton’s rules.

Permitted deductions must be entered according to the applicable rules. For figures indexed each year, such as the 3a third-pillar maximum, the LPP coordination threshold/deduction, the AD/AC maximum, LAMal average premiums and the median salary, the official value for the year must be verified. The first operational tool remains dichiarazione delle imposte, with separate attention to the three components.

Operational details

Separating taxes, salary and health insurance

The practical reading starts with the payslip, but does not stop at the deductions. AVS/AHV, LPP/BVG, AD/AC and LAINF/LAA belong to social security or social insurance; the three taxes, on the other hand, follow the tax structure. Separating these areas prevents confusing a salary contribution with a tax item.

Payslip percentages

The percentages help identify the items, but do not replace checking the permitted deductions. For AVS/AI/IPG, the employee's share is 5.3%, while the total with the employer is 10.6%. AD/AC is 1.1% up to the annual maximum. LAINF/LAA ranges from 0.7% to 1.5% depending on the sector. For the coordinated LPP salary, the figures are 7% between ages 25 and 34, 10% between 35 and 44, 15% between 45 and 54, and 18% from age 55 until the reference age.

LAMal/KVG follows a different logic. For residents, health insurance is compulsory and must be taken out within 3 months of arrival. It is financed through per-capita premiums; it is neither a tax nor a salary contribution. Premiums vary by canton and region, while premium reductions are a cantonal subsidy. For adults, the available deductibles are CHF 300, 500, 1000, 1500, 2000 and 2500.

The comparison at national level must also take employment into account: there is no federal minimum wage, while some cantons have their own. UFAS/BSV concerns AVS/AI/LPP social security and does not set taxes; UST/BFS produces statistics and does not determine tax rates.

Finally, figures indexed annually should not automatically be carried over from one year to the next. To distinguish the tax burden from premiums and other recurring costs, you can consult costo della vita in Svizzera, always checking the official values for the year.

Key points

Online procedure: five steps

An orderly procedure avoids mixing up areas of responsibility. The process for the canton of Vaud can be organized into five steps, without replacing the instructions of the cantonal administration.

1. Define the cantonal scope

Identify the canton and municipality to which the declaration relates. If the reference is Vaud, start with the applicable cantonal deadline and the online procedure of the competent administration. The municipality remains relevant because it applies its own multiplier to the cantonal component.

2. Arrange the three components

In the online process, separate direct federal tax, cantonal tax and municipal tax. For the first, the reference is AFC/ESTV; for the other two, the cantonal administrations are responsible. This division makes it clearer which instruction to follow when a law, rate or multiplier appears.

3. Check the permitted deductions

Enter only the deductions provided for by the applicable rules. For pillar 3a and the LPP coordination threshold/deduction, use the official value for the year. The same check applies to the AD/AC ceiling, average LAMal premiums and median salary, because these figures are indexed annually.

4. Keep salary and LAMal separate

Before submitting, identify the AVS/AI/IPG, AD/AC, LAINF/LAA and LPP/BVG items as salary or pension contributions. LAMal/KVG remains compulsory insurance for residents, with per capita premiums and a cantonal reduction; it is neither a tax nor a salary contribution. If the insurance arises from arrival in Switzerland, the specified period is 3 months.

5. Complete the procedure by the deadline

Compare the data entered with the cantonal deadline and complete the submission through the prescribed online process. For tax-related questions, the reference is the authority responsible for the relevant component, not UFAS/BSV or UST/BFS, which have social security or statistical responsibilities. For an initial orderly estimate, use calcolatore delle imposte.
