Doing business in Slovakia vs Czechia: taxes, contributions and admin

Slovakia and Czechia are as close as any two countries get — a shared language, a similar mindset and closely linked markets. Which makes it all the more surprising, when you set up a company, to find that the business environment differs in many ways. Tax rates, VAT, contributions and administration each move at their own pace in the two countries, and from 2026 some of the differences have grown wider still.

This overview is not a tax manual but a signpost for an entrepreneur weighing where to launch or move their activities. We look at what matters most to a company and a sole trader alike: how much is paid on profit, how VAT works, what happens with dividends and how much paperwork it all involves.

Income tax: one rate versus brackets

The biggest difference shows up straight away in the tax on company profit. In Czechia a limited liability company pays corporate income tax at a single rate of 21%, unchanged for 2026 — whether it earns a hundred thousand or ten million, the rate is the same. Slovakia, by contrast, splits companies into three brackets: 10% on income up to EUR 100,000, 21% from EUR 100,000 to five million, and 24% above five million.

In practice this means a small Slovak company may have a lower rate than a Czech one, while a large company pays more. Czechia relies on predictability — one rate for everyone, one you can plan around for years. A detailed overview of Czech company taxes is in the article on what taxes a company pays in Czechia.

VAT: a lower standard rate in Czechia

With value added tax the difference is visible at a glance. The Czech standard rate is 21% and the reduced rate 12%; the Slovak standard rate rose to 23% in 2025, alongside two reduced rates — 19% and 5%. The standard rate is therefore two percentage points lower in Czechia, which is far from negligible on ordinary sales of goods or services.

When you become a payer also differs. In Czechia mandatory registration arises once turnover exceeds CZK 2,000,000 in a calendar year, so a smaller sole trader can operate as a non-payer for a long time. When and how to register in Czechia is covered in the text on VAT and registration.

Contributions and paying out profit

When a shareholder pays out a share of profit, dividend taxation comes into play — and here Slovakia is gentler. Dividends from 2025 profit are subject to a 7% withholding in Slovakia, against 15% in Czechia. Bear in mind, though, that Czech profit is taxed in two tiers: first 21% at the company level, then 15% when paid to the shareholder.

Both countries levy social and health insurance contributions, but their levels and minimum bases change year to year and are calculated differently. For a sole trader the chosen regime is often decisive — Czechia offers the popular flat-rate tax, which combines tax and contributions into a single monthly payment and greatly simplifies the admin.

Administration: where 2026 adds more

Paperwork is often what wears an entrepreneur down more than the tax itself. Czechia has bet on going digital — the data box is mandatory for companies and sole traders, and most dealings with the authorities happen online. Slovakia, on the other hand, introduced a financial transaction tax in 2025 and, from 2026, widened progressive personal income taxation with 30% and 35% brackets on higher incomes, which means another layer of records and planning.

Stability and predictability are among the reasons entrepreneurs from Slovakia and elsewhere choose Czechia. You can read more about that motivation in the article on why foreign entrepreneurs choose Czechia.

What to take away

There is no universal “better”. Slovakia attracts with a lower income tax rate for small companies and gentler dividend taxation; Czechia builds on flat rates, a lower standard VAT and a predictable environment that does not change every year. For many entrepreneurs it is precisely this stability, and the proximity of a large market, that tips the scales.

Frequently asked questions

Where is company profit taxed less — in Slovakia or Czechia?

It depends on the size of the company. A small Slovak company with income up to EUR 100,000 pays 10%, which is less than the Czech flat rate of 21%. Larger Slovak companies, however, pay 21%, or even 24% above five million euros, so the Czech environment is more predictable with a single rate for all.

What is the difference in VAT between Slovakia and Czechia?

The Czech standard VAT rate is 21%, the Slovak one 23%. Both countries also have reduced rates — Czechia 12%, Slovakia 19% and 5%. In Czechia the registration obligation also arises only once turnover exceeds CZK 2,000,000 a year.

How does dividend taxation differ?

Slovak dividends from 2025 profit are subject to a 7% withholding, Czech ones 15%. In Czechia, though, profit is taxed in two tiers — first 21% company tax and then 15% on payout to the shareholder, which should be taken into account when comparing.
