Can I earn on the side without a trade licence in Czechia?
Yes — as long as it's truly occasional. One-off gigs (mowing a garden, tutoring, selling garden surplus, helping on a build) fall under occasional income (§ 10): up to CZK 50,000 per year it's tax-exempt, levy-free and unreported. Above 50,000 the whole amount goes into your tax return (not just the excess). The decisive line isn't the money but systematicity: repeat orders, advertising, a customer base = business requiring a trade licence — otherwise it's unauthorised business with fines reaching hundreds of thousands. A bricklayer moonlighting every weekend can't hide under the 50k limit.
📋 The rules
- Occasional income up to CZK 50,000/yr: no tax, no levies, no reporting
- Above 50,000: the entire income goes into the tax return (§ 10)
- Systematic = business: repetition, ads, customers → trade licence needed
- Selling your own garden surplus: also occasional income
- Rentals and selling goods have their own tax regimes
🔓 Exceptions
- Royalties, work agreements (DPP/DPČ) and company payouts run under their own regimes
- Beekeepers: special exemption per hive up to a set count
⚠️ Penalties & fines
Undeclared income above the limit: back taxes plus penalties. Systematic business without a licence: unauthorised-business fines (misdemeanour up to ~CZK 500,000; serious forms criminal).

❓ Frequently asked
How much can I earn tax-free?
Occasionally up to CZK 50,000 a year — exempt, no return; exceed it and the whole amount is taxed.
Where's the line between a gig and a business?
Systematicity: a one-off favour is fine; repeat jobs with advertising need a trade licence regardless of the amount.
Must I issue receipts?
Not invoices (you're not an entrepreneur), but written payment confirmations protect both sides.
Does the limit cover selling on Vinted?
Selling your own used items is a different regime (exempt after holding periods); platforms report 30+ sales/€2,000 (DAC7) since 2023.
What about a part-time job at a company?
That's dependent work — DPP/DPČ agreements taxed by the employer, not occasional income.
