Nobody moves to Prague dreaming about tax forms. You came for the architecture, the beer, the quality of life, maybe the tech scene. And then January rolls around and someone at work mentions that you need to file a “daňové přiznání” and suddenly you’re googling Czech tax vocabulary at midnight, wondering if you’ve been underpaying for three years.

I’ve been there. Most of us have. Czech taxes aren’t impossibly complicated, but they’re complicated enough that getting things wrong is easy — especially in a year like 2026, where the rules have shifted in ways that directly affect how much money stays in your pocket.

So here’s the deal: I’m going to walk through the 2026 tax landscape in plain language. No jargon avalanche. No disclaimers every other sentence. Just the stuff that actually matters if you’re an expat earning money in Czechia.

The basics: two tax rates, one important number

Czech income tax works on a two-tier system. If your annual taxable income is under 1,762,812 CZK, you pay 15%. If it goes above that threshold, everything above gets taxed at 23%. That’s it. Two rates. One cutoff.

For most employed expats, this is handled automatically — your employer withholds taxes from your paycheck, and unless you have other income sources, you might not even need to file a return. The system works quietly in the background.

But here’s where it gets interesting. That 1.76 million CZK threshold? It’s roughly equivalent to earning about 147,000 CZK per month gross. If you’re in tech, finance, or senior management — which describes a decent chunk of Prague’s expat workforce — you might be closer to that line than you think. And once you cross it, every additional crown gets taxed at 23% instead of 15%.

Freelancers: the 60/40 model is still your best friend

If you’re self-employed in Czechia — what the Czechs call an OSVČ (osoba samostatně výdělečně činná) — then you already know about the famous 60/40 flat-rate expense deduction. And in 2026, it still works the same way: you can automatically deduct 60% of your gross income as business expenses, and only pay tax on the remaining 40%.

Let’s make this concrete. Say you earned 1,500,000 CZK gross last year as a freelancer. Under the 60/40 model, your taxable income is just 600,000 CZK. At 15%, that’s 90,000 CZK in income tax. Without the flat-rate deduction, you’d be taxed on the full 1.5 million — a dramatically larger bill.

The catch? The flat-rate expense cap is 2,000,000 CZK (meaning it works for gross income up to about 3.33 million CZK). Beyond that, you need to track actual expenses. And here’s the part that trips people up every January: minimum social and health insurance deposits went up in 2026. The minimum monthly deposits increased because they’re pegged to the average wage, which rose. If you’re a lower-income freelancer, your mandatory payments are now higher even though the rates themselves didn’t change.

Crypto and investments: the three-year rule

This is the change that has a lot of expats talking. If you’re holding crypto or investment securities, the Czech Republic has become one of the more favorable places in Europe to do so — provided you’re patient.

Here’s how it works in 2026: profits from crypto assets and investment securities are completely tax-free if you’ve held them for at least three years. Alternatively, if your total annual gains from these assets are under the €4,000 threshold (roughly 100,000 CZK), they’re also exempt regardless of holding period.

There’s one important nuance that changed this year. The previous 40 million CZK exemption limit for tax-free capital gains has been abolished for business shares and securities — but it still applies to crypto assets. In practice, this mostly affects high-net-worth investors selling large equity stakes, not the average expat with a diversified portfolio. But if you’re sitting on a significant amount of company shares, it’s worth paying attention.

Stock options: the change nobody saw coming

If you work for a tech company that offers employee stock options — and in Prague’s startup scene, that’s a lot of people — then 2026 brought a genuinely significant change that could save you thousands.

Previously, when you exercised stock options from your employer, the gain was treated as employment income. That meant it was subject to income tax plus social security and health insurance contributions. For a big option exercise, the extra levies could easily eat 30-40% of the gain.

Starting in 2026, qualifying employee stock option plans get a new, much more favorable treatment. The income is now classified as “other income” rather than employment income. The practical difference? No social security contributions. No health insurance contributions. You still pay income tax (15% or 23%), but you skip the social and health levies entirely.

The conditions for “qualifying” plans are specific — the options need to meet certain legal requirements about vesting, exercise price, and holding period. But if your company’s plan qualifies, this is real money back in your pocket.

The small changes that add up

Beyond the headline changes, 2026 brought a handful of quieter adjustments that might affect you:

Spouse deduction — new restriction. You used to be able to claim a tax deduction for a low-earning spouse (under 68,000 CZK/year). In 2026, there’s a new condition: the spouse must also be caring for a child under 3 years old. If you’ve been claiming this deduction and your youngest kid just turned four, that benefit is gone.

Property tax indexation. For the first time, property tax in Czechia is now automatically indexed to inflation. If you own property, expect your annual bill to creep up each year without any new legislation being needed. It’s a small increase individually, but it signals a shift in how the government thinks about property taxation.

All-digital communication with insurers. Starting January 2026, all communication between employers, self-employed individuals, and health insurance companies must be conducted entirely digitally. No more paper forms. If you’ve been doing things the old-fashioned way, it’s time to set up a datová schránka (data box) if you haven’t already.

The 183-day question: are you even a Czech tax resident?

Here’s a foundational question that some expats never properly answer: where are you a tax resident? If you spend 183 days or more per calendar year in the Czech Republic, you’re considered a Czech tax resident, which means Czechia has the right to tax your worldwide income.

If you’re under 183 days, you’re a non-resident — you only pay Czech tax on Czech-sourced income. This matters enormously if you also earn money abroad, have rental income from another country, or do consulting work for clients outside Czechia.

Most expats living and working in Prague are clearly tax residents. But if you travel heavily, work remotely from other countries for extended periods, or split your time between Czechia and elsewhere, the residency question gets complicated. And getting it wrong can mean being taxed twice — or worse, being non-compliant in two countries simultaneously.

Czech taxes aren’t designed to be punitive, and in many ways the system is surprisingly favorable — especially for freelancers using the 60/40 model and for patient crypto investors. But the rules change every year, and the penalties for getting things wrong are real. The best thing you can do is stay informed, file on time, and ask for help when the forms stop making sense.

Because let’s be honest — you didn’t move to Prague to become a tax expert. You moved here for everything else. The taxes are just the price of admission. Make sure you’re paying the right price.
