tailored. comprehensive. for you.
Would you rather have your Swiss tax return completed than spend your evenings with receipts and forms in a language you are still learning? We take care of the data entry – fully digital, at a price you know in advance.
You fill in the form just below and get access to our client portal smzh prisma, where you upload your documents easily and securely. Our tax specialists enter your figures completely and correctly and walk you through the result. You review, sign and submit it yourself – so you stay in control and know exactly what is being filed.
In English, at one of our offices in German-speaking Switzerland or entirely online – whichever suits you.
A few brief details help us prepare your tax return properly.
We are independent of banks, insurers and product providers, and we work on transparent flat fees – no commissions, no sales pressure.
You know what your tax return costs before we start. A flat fee instead of hourly billing – no follow-up invoices and no hidden effort.
We represent no third-party interests. The person completing your tax return will not follow up by selling you an insurance policy or a fund.
Swiss tax forms are in German, French or Italian. Your conversation with us is not. You upload everything to smzh prisma and get one named contact person who explains each line in English.
If something stands out while we work – unused deductions, open pension or property questions – we tell you. Whether you explore it further in a tax advice session is entirely your call.
From the form to a tax return ready for your signature – step by step through our client portal smzh prisma, without you having to chase anything.
Complete the form at the top of this page – a few brief details about your situation are enough.
We get back to you and set up your access to our client portal, smzh prisma.
Upload the PDF of last year's tax return. Many figures are then carried over automatically, which cuts the work down considerably for you.
No PDF, or this is your first Swiss return? Then you simply enter the information manually – that works just as well.
You review the carried-over information and upload this year's documents, such as your salary statement (Lohnausweis), bank and pension certificates and receipts for deductions.
You get a checklist so nothing is forgotten.
Our tax specialists enter your figures completely and correctly and send you the finished return for review.
If something is missing or unclear, we come back to you straight away rather than at the very end. Anything unusual, and any deduction you are not yet using, gets raised then.
Please check all the details carefully. Signing and filing on time with the responsible tax office is done by you – this is what the law requires, and it keeps you in control.
You receive our invoice by post or email.
Flat fees rather than hourly rates. You know the price before we begin work.
For employees with a straightforward situation: salary statement, bank accounts, pillar 3a and the usual deductions.
For jointly assessed couples and families, including child deductions, childcare costs and both partners' pension contributions.
Single person with property CHF 210.00, family with property CHF 248.00. For securities portfolios, self-employment, foreign income or several cantons you receive a transparent quote in advance.
Whether your situation is simple or tangled, what matters is that the figures are complete and correct when they are filed.
Your first Swiss tax return, in a system that works differently from the one you know. We explain how Swiss taxation works and take the paperwork off your desk.
If you hold a B permit and earn above the threshold, you move from withholding tax (Quellensteuer) to ordinary assessment. That first return is where deductions are won or lost.
Child deductions, childcare costs, two salary statements and two pension situations: joint assessment is where things get missed.
Imputed rental value (Eigenmietwert), mortgage interest and maintenance costs. This is where careful entry is worth real money – see taxes on home ownership.
Unless stated as Switzerland-wide, the figures below apply to the Canton of Zurich. Other cantons set their own deadlines – just ask us.
The ordinary filing deadline for individuals in the Canton of Zurich, in the year following the tax year. The cantonal finance directorate may extend it generally in some years.
The latest date to which the deadline can be extended. The request must reach your municipal tax office before the ordinary deadline expires.
The maximum pillar 3a deduction for the 2026 tax year for employees with a pension fund. Without a pension fund it is CHF 36'288, capped at 20 % of earned income.
Above this gross annual income, people taxed at source are subject to mandatory subsequent ordinary assessment. Below it, assessment is possible on request – within a deadline.
These are the questions we work with every day. Just fill in the form at the top of this page – we will get back to you.
For a single person with a straightforward situation it costs CHF 132.00, and for jointly assessed couples and families CHF 168.00. With property it is CHF 210.00 (single person) and CHF 248.00 (family). For securities, self-employment, foreign income or several cantons you receive a transparent quote in advance. You know the price before we start.
No. We provide an administrative support service: we enter your figures and go through them with you. Reviewing, signing and submitting the return is done by you, and we do not represent you before the tax authorities. In exchange, you know exactly what is being filed in your name.
smzh prisma is our client portal. Once you have filled in the form, you receive your login details and can upload your documents there easily and securely. If you add the PDF of last year's tax return, many figures are carried over automatically, which saves you time.
No. The official tax forms are in the language of your canton, but the entire process with us – the form, smzh prisma, our questions and the walkthrough of your completed return – runs in English. We explain what each German term on the form actually means.
Usually your salary statement (Lohnausweis), bank and postal account balances as at 31 December, pillar 3a and pension fund certificates, insurance premiums, and receipts for deductions such as further education, childcare or property maintenance. You receive a checklist in smzh prisma so nothing is forgotten.
Above a gross annual income of CHF 120'000 you are subject to mandatory subsequent ordinary assessment and must file. Below that threshold you can request assessment, which is often worthwhile if you have significant deductions – but the request is subject to a deadline. We can tell you which situation applies to you.
In the Canton of Zurich the deadline for individuals is 31 March of the following year. An extension is requested from your municipal tax office before that deadline expires and is granted until 30 November at the latest. Other cantons set their own deadlines. Demand peaks in the weeks before 31 March, so starting early gives you more room.

In connection with tax returns, smzh ag provides an administrative support service.
This does not constitute tax law advice, does not include representation before the tax authorities, and does not include submitting the tax return on the client's behalf. Reviewing, signing and submitting the tax return is done exclusively by the client.
Deadlines and deduction amounts refer to the Canton of Zurich and the 2026 tax year respectively. The information published by the competent cantonal tax administration is authoritative.
