Current information for your tax return

Starting with the 2025 tax year, tax returns can only be submitted online from 1 January 2026 onwards. Supporting documents must be transmitted securely, preferably in PDF format.
If you are unable to provide your documents as PDFs, we will gladly take care of the entire scanning and upload process for you. Please do not send photographs of your documents.
In addition to the tax reports for your investment portfolios, you will now also receive electronic statements detailing your health insurance expenses and Pillar 3a contributions.

The abolition of the imputed rental value is not expected to take effect before the 2028 tax year, with 2029 currently considered the more realistic implementation date. However, the taxable property value will remain in place. In the Canton of Zurich, a revised valuation model has been introduced and will apply from the 2026 tax year. The capitalisation rate for apartment buildings and commercial properties now ranges from 4.8% to 6.5%, compared with the previous rate of 7.05%. In addition, the hardship provision in the Canton of Zurich has been reinstated with effect from 1 January 2026.

Contributions to the Swiss Pillar 3a pension scheme and voluntary purchases into your occupational pension fund are tax-deductible at your highest marginal tax rate. We would be pleased to calculate your individual tax savings based on your personal circumstances.
Pillar 3a: The third pillar is an excellent long-term savings and wealth-building solution. It is generally recommended from around the age of 25 to 30 and is particularly effective when combined with investment fund-based solutions. Occupational Pension Fund: Voluntary pension fund purchases can be used either to increase your future retirement benefits or as a tax-efficient savings strategy. They are particularly beneficial from around the age of 50 or if you plan to continue working in Switzerland for another five to ten years. Please note that a statutory blocking period of 36 months applies.

From 1 January 2025, life annuities are no longer taxed at a flat rate of 40%. Instead, the taxable portion of a life annuity is based on the actual investment return generated by the underlying life insurance policy and will generally be lower. From the 2025 tax year onwards, the applicable taxable percentage will be stated directly on the annuity certificate. As a result, the taxable portion of the annuity is expected to be significantly lower than the previous flat rate of 40%.

From the 2025 tax year onwards, employed taxpayers may deduct insurance premiums of up to CHF 1,800 for Direct Federal Tax (DFT) and CHF 2,900 in the Canton of Zurich. For each child, the deduction amounts to CHF 6,800 for Direct Federal Tax and CHF 9,300 in the Canton of Zurich.
Childcare expenses of up to CHF 25,800 for Direct Federal Tax and CHF 25,000 in the Canton of Zurich are also deductible. As of the 2025 tax year, courses and childcare provided during school holidays may also qualify for tax deductions. Only the childcare portion of the costs is deductible, provided that the parent who would otherwise care for the child is gainfully employed. This applies to both married couples and unmarried cohabiting couples where both parents are employed.  

Maintenance payments  Maintenance payments may be recognised for tax purposes even without a written agreement or formal maintenance contract. However, they must correspond to the officially recognised child maintenance guidelines and generally amount to at least CHF 1,350 per child per month. Proof of payment, such as bank or postal transfer records, is required. Lower amounts, for example CHF 120 per month, are generally not accepted. Married tax rate: The married tax rate, together with the child deductions and deductions for third-party childcare expenses, is transferred to the parent who receives the maintenance payments. School expenses: If school costs are shared by both parents, these may also qualify as maintenance payments, provided that this arrangement has been agreed upon in writing in advance.

Partial Retirement: From the 2025 tax year onwards, up to three partial lump-sum withdrawals are permitted instead of the previous two. Each withdrawal must amount to at least 20% of the available pension capital. Divorce: For regular pension fund buy-ins made following a divorce, the statutory 36-month blocking period no longer applies. Leaving Switzerland: Tax-advantaged pension fund buy-ins made shortly before relocating abroad will be significantly restricted in the future. These changes are intended to prevent the use of pension fund contributions as a means of avoiding Swiss income tax.

As of 2025, the Republic of Moldova and Georgia have been added to the Automatic Exchange of Information (AEOI) framework. From that point onwards, tax information will also be exchanged automatically with these countries.

Interest: In the Canton of Zurich, interest of 1% is charged if provisional tax payments are made too late or are insufficient. Conversely, interest of 1% is credited if provisional tax payments are made early or exceed the amount of the final tax assessment. If payment is made after the due date stated on the final tax assessment, default interest of 4.75% is charged. The applicable rules vary between cantons. For example, from 1 January 2026, the Canton of Zug will apply a balancing interest rate of 2%. This means that interest of 2% will be credited on provisional tax payments until the final assessment is issued, while the same rate will be charged on taxes that remain unpaid after the due date. 2025 Tax Return: Interest payments made during 2025 are tax-deductible. In addition, any outstanding tax liabilities as at 31 December 2025 may also be taken into account for tax purposes.
