Opole

Poland · Europe · 127,387 people · Europe/Warsaw · PLN

Opole is a compact city on the Oder with a pleasant market square, river islands and the long-running National Festival of Polish Song each summer. It is affordable and easygoing, with Wrocław about an hour away by train and Katowice airport within reach. Its size is the main limit: few international residents, quiet evenings and no airport of its own.

Do you pay tax here on income from abroad?

Tax status · Poland

Residents pay 12%–32% on worldwide earnings (+4% above PLN 1m), 19% on investments; IT freelancers often 12% of revenue

Worldwide income

Once resident, Poland taxes your worldwide income. A salary from abroad pays 12% up to PLN 120,000 and 32% above, plus a 4% solidarity levy above PLN 1,000,000. Freelancers can instead pick 19% flat on profit or a lump sum on revenue (12% for most IT services), plus ZUS and health contributions. Dividends, interest and share gains pay 19%. Newcomers may get up to PLN 85,528 a year tax-free for 4 years, or a PLN 200,000 flat tax on foreign income.

On the nomad visa

Poland has no digital nomad or remote-work visa, and no immigration status changes how you are taxed. Whether you are an EU citizen, on a visa-free Schengen stay or on a national visa or residence permit, you become resident under the centre-of-interests or more-than-183-days test. Before that, pay for work you physically do in Poland is still Polish-source income under the Act, although a tax treaty with your home country may exempt a short stay. Non-EU nationals also need a status that lets them register a business before freelancing through a Polish sole proprietorship.

Salary from a foreign employer or fees from foreign clients

Taxed12%–32% progressive (plus 4% solidarity levy above PLN 1,000,000); self-employed can opt for 19% flat on profit or a 2%–17% lump sum on revenue (12% for most IT services)

Salary from a foreign employer is taxed on the scale: 12% up to PLN 120,000 of taxable income and 32% above, with a PLN 3,600 tax reduction that works like a PLN 30,000 tax-free amount (art. 27). With no Polish payroll, you pay monthly advances yourself (art. 44(1a)). Under 26, up to PLN 85,528 of salary is exempt (art. 21(1)(148)). Freelancers register a sole proprietorship and choose the scale, 19% flat on profit with no tax-free amount (art. 30c; not allowed if you serve your employer of the same year in the same role), or ryczałt on revenue with no cost deductions (see regimes). Each comes with ZUS: after an optional 6 months with only the health contribution and 24 months on a reduced base of PLN 1,441.80, full social contributions on the PLN 5,652 minimum base are up to PLN 1,926.76 a month (including voluntary sickness insurance). The health contribution is 9% of income on the scale, 4.9% on the 19% flat tax (minimum PLN 432.54 a month), and fixed amounts on ryczałt. Social security for employees of a foreign employer depends on EU rules or a bilateral agreement and is not covered here. Foreign tax is relieved by exemption with progression or a credit, as the treaty says (art. 27(8)–(9)).

On the nomad visa

Ulga na przyjazd / ulga na powrót (relief for people moving to Poland)4 years
Up to PLN 85,528 a year of salary, mandate-contract and business income (on the scale, 19% flat, IP Box or ryczałt) is exempt from income tax. The cap is shared with the under-26 and other similar reliefs. Social and health contributions are still due, and income above the cap is taxed normally (PIT Act, art. 21(1)(152) and (43)–(44)).
Who qualifies: People who become Polish tax resident by moving to Poland after 2021, were not resident in the previous three calendar years, have not used the relief before, hold a residence certificate for the years abroad, and either hold Polish, EU, EEA or Swiss citizenship or a Karta Polaka, or lived those three years in the EU/EEA, Switzerland, the UK, the US, Canada, Australia, New Zealand, Japan, South Korea, Chile, Israel or Mexico.
Ryczałt od przychodów zagranicznych (PLN 200,000 lump sum on foreign income)10 years
A fixed PLN 200,000 a year (pro rata in the year of arrival) covers all income earned outside Poland, whatever its size; a spouse or child can join for PLN 100,000. Polish-source income is taxed normally. Pay for work you physically do in Poland is probably Polish-source rather than foreign, so this mainly suits large foreign investment income; check with an advance ruling. The right is lost if you miss a payment or the PLN 100,000 spending, or move away.
Who qualifies: People who move their residence to Poland after not being resident for at least five of the six previous tax years. You opt in by the end of January after the year of the move, attaching proof of your former tax residence, and from the following year must spend at least PLN 100,000 a year on listed purposes such as the economy, science, culture or sport (PIT Act, art. 30j–30p).
Ryczałt od przychodów ewidencjonowanych (lump sum on revenue)no fixed end
Tax on gross revenue with no cost deductions or tax-free amount: 12% for software, IT consulting and system-management services; 14% for architecture, engineering and specialist design; 15% for management consulting, advertising and many other business services; 17% for liberal professions; 8.5% for other services. Not counted for the 4% solidarity levy. The health contribution is fixed by revenue: PLN 498.35 a month up to PLN 60,000, PLN 830.58 up to PLN 300,000 and PLN 1,495.04 above (2026).
Who qualifies: Sole proprietors and partnerships whose previous-year revenue did not exceed €2,000,000. Popular with IT contractors who invoice foreign clients.
IP Box (5% on qualified intellectual-property income)no fixed end
5% instead of 12%–32% or 19% on qualified income from that IP, scaled by a nexus ratio that rewards in-house development (PIT Act, art. 30ca).
Who qualifies: Sole proprietors who create, develop or improve qualifying IP, including copyright in computer programs, as part of their own research and development, and keep the separate records the law requires.
