Swiss Tax Assessment: What If the Tax Office Gets Your Income Wrong?
The One Where the Tax Office Decides What You Earned
You open a letter from the Swiss tax office.
You look at the figures.
And you think: “Where on earth did they get THAT number from?”
Perhaps the income is much higher than you actually earned. Perhaps the estimated wealth looks completely wrong. Or perhaps the figures are surprisingly low, and you're wondering whether you've just got lucky.
Welcome to the world of estimated tax assessments in Switzerland.
In the first solo episode of Tax and the City, Julia Tatje, Swiss tax specialist and founder of taxum AG, explains what happens when the Swiss tax authorities assess your income and wealth without a complete tax return.
Known as an Ermessensveranlagung or Ermessenseinschätzung in German, an estimated tax assessment can arise when the authorities don't have sufficient information to determine your taxable income and wealth through the normal assessment process.
But here's the part many people misunderstand: an estimated assessment isn't just a suggestion you can correct whenever you feel like it.
There are deadlines. There are specific requirements for challenging the assessment. And whether the estimate is too high or too low, ignoring it can create problems.
Julia explains why the tax office may estimate your income, what to check when you receive an assessment, why an objection requires more than simply saying the numbers are wrong, and how a tax assessment differs from a tax bill.
Because sometimes the most expensive mistake isn't getting your Swiss tax return wrong.
It's leaving the letter unopened.

The Bottom Line
If you've received an estimated tax assessment: Don't ignore it. Read the document carefully and check what the tax authorities have assessed.
If the income or wealth figures are too high: Don't assume you can correct them later. Check the objection deadline and the specific requirements for challenging an estimated assessment. Simply disagreeing with the figures may not be enough.
If the figures are too low: Don't assume the estimate is a tax-free bonus. Your reporting obligations and the applicable procedural rules still matter.
If you're confused by the paperwork: A tax assessment determines the relevant taxable amounts and rates. A tax bill determines the amount payable. They are connected, but they are not the same thing.
And if you're unsure what to do next: Seek advice promptly, ideally well before any deadline expires.
The key message? An estimated tax assessment is not a reason to panic, but it is a reason to act.
