WELCOME TO ACONTA

The joy found in helping people and an affinity for numbers makes Aconta GmbH what it is. Whether you are looking to free up time or would rather not concern yourself with numbers at all doesn’t matter. We take care of your Swiss tax return and the questions that come with it.

Our core strengths are tax consulting and tax preparation for expats living in Switzerland. They grew out of years of finance work, including an international non-profit (2002–2008) and the CFO role at a Zürich non-profit.

Aconta GmbH serves English-speaking expats and self-employed people in German-speaking Switzerland, most of them in the Zürich and Zug areas. We prepare Swiss tax returns, handle source tax reassessments and Swiss withholding tax refunds, and provide tax consultations. Our primary service is to reduce the stress people often feel when moving to a new country with a different language or when running a business and needing to keep up with regulations. Our clients tell us that they appreciate not having to deal with correspondence to the tax authorities and keeping up with deadlines.

Please do not hesitate to contact us.

Individual Swiss Tax Return

When completing the annual tax return for income and wealth taxes, we are happy to advise you or do this work completely for you.

Swiss Dividend Tax Refund

Living abroad with Swiss shares? Switzerland withholds 35% of every dividend. Under most tax treaties you get 20% of the dividend amount back: CHF 200 for every CHF 1,000 paid out. We file the claim for you.

Source Tax Reassessment

If you believe that the wrong withholding tax rate was applied or that you could claim additional deductions we can help you file a source tax reassessment.

… both Katarzyna and Emanuel Häsler have provided outstanding support throughout my Swiss tax filing process. From the very beginning, they made everything straightforward by providing a clear checklist of all the documents I needed to get started. … I never had to worry because they took care of every step and kept me informed throughout the process.

This is the 11th year that I have been using the services of Aconta GmbH for the preparation of my tax return. Aconta has always been responsive and proactive in handling communication with the tax authorities, helping to address any issues efficiently throughout the process.

I've been filing my taxes with Aconta for the past couple of years. They're quick, responsive and have a host of plans that can suit your need. One service I appreciated is the proxy where they're able to intercept comms on your behalf. For an expat still learning German, this was super helpful. I also appreciated that they extended the tax deadline before I even communicated it. Overall, highly recommend them!

I've had a great experience working with Aconta on my tax declarations over several years now. I can highly recommend them: quick, efficient and ever so friendly! Their pricing system is fair and transparent, and they definitely take care of their customers from one year to the next one: be it friendly reminders of the upcoming deadlines, speedy communication with the authorities, or detailed explanations of what comes up next in the tax return process. Will definitely come back next year!
