Remote Work Taxes in Poland for Foreigners 2026 — What You Must Know
Poland has become a popular base for remote workers and digital nomads from across Europe and beyond. Whether you're an EU citizen working remotely for a foreign employer or an expat running a B2B consultancy from Warsaw, understanding your Polish tax obligations is non-negotiable.
This guide focuses on the tax rules that apply specifically to foreigners working remotely in Poland in 2026.
Tax Residency in Poland — The 183-Day Rule
Polish tax law draws a clear line between residents and non-residents:
You are a Polish tax resident if:
- You spend more than 183 days in Poland in a calendar year, OR
- Your center of vital interests (family, main home, primary economic activity) is in Poland
Both conditions are evaluated independently. Meeting either one makes you a Polish tax resident — even if you spend under 183 days in the country.
Consequence: Polish tax residents pay income tax in Poland on their worldwide income — including salaries from foreign employers, freelance income from foreign clients, and investment returns abroad.
Non-residents pay Polish PIT only on income sourced in Poland.
Double Taxation Treaties (DTT)
Poland has signed double taxation agreements with over 90 countries. These treaties prevent you from being taxed twice on the same income.
| Country | Treaty Type | Key Rule |
|---|---|---|
| Germany | OECD Model | Residence determines tax country for employment |
| UK | Bilateral | Employment income taxed where work is performed |
| Netherlands | OECD Model | 183-day rule applies for dependent employment |
| USA | Bilateral | Complex tie-breaker rules apply |
| Ukraine | Bilateral | Residency-based allocation |
How it works in practice:
If you're a Polish tax resident employed by a German company and working from Warsaw, you declare this income in Poland and potentially claim a credit or exemption for any German tax withheld. The specific method (exemption with progression or credit method) depends on the applicable treaty.
Always verify the current treaty text — Poland has renegotiated several agreements in recent years.
Withholding Tax on Foreign Income
Some foreign countries will automatically withhold tax on payments to Polish residents (especially dividends, royalties, and certain service fees). Key rates:
- Dividends: typically 5–15% under treaty (vs. standard 19% Polish tax)
- Royalties/IP income: 5–10% under most treaties
- Employment income: varies; many treaties eliminate source-country taxation if you work from Poland
You claim credit for withheld foreign tax on your Polish annual PIT return (PIT-36 or PIT-36L). Keep documentation: foreign tax certificates (equivalent of Polish PIT-11) are essential.
Declaring Foreign Income in Poland
As a Polish tax resident, you file your annual declaration by April 30 of the following year.
Forms used:
| Situation | Form |
|---|---|
| Foreign employment + Polish sources | PIT-36 (progressive scale) |
| Foreign income as self-employed (JDG) | PIT-36L (flat tax) or PIT-28 (lump-sum) |
| Foreign dividends | PIT-38 |
What you must report:
- Salary from a foreign employer (even if tax was withheld abroad)
- Freelance income from foreign clients
- Rental income from property abroad
- Dividends and capital gains from foreign accounts
Pro tip: Keep all foreign pay slips, bank statements, and employer-issued tax certificates. Polish tax offices increasingly ask for documentation of foreign income.
Remote Work for a Foreign Employer — Special Scenarios
EU/EEA Employer, You're in Poland
If your employer is in the EU/EEA and you work entirely from Poland, you are generally taxable in Poland on your full salary. Your employer may need to register a payroll obligation in Poland or you may need to handle tax yourself.
Many foreign employers issue a net payment and you self-report via your own JDG or as an individual. Consult a tax advisor — the obligations differ case by case.
Non-EU Employer (USA, UK, Canada)
Same principle applies: if you're a Polish tax resident, Poland taxes your worldwide income. The treaty with the employer's country determines how double taxation is avoided. UK treaty post-Brexit is still active but worth double-checking for your specific income type.
Social Security (ZUS vs. Foreign Social Security)
Tax residency and social security residency are separate questions. If you are employed by a foreign company and work in Poland, an A1 certificate from your home-country social security authority may allow you to remain in the foreign system for up to 24 months. After that, Polish ZUS generally applies.
Common Mistakes Foreigners Make
- Assuming 183 days is the only test. Vital interests alone can make you a Polish tax resident regardless of time spent.
- Not filing because income is "foreign." Polish residents must report worldwide income.
- Ignoring social security obligations. ZUS and income tax are separate systems with different rules.
- Missing the April 30 filing deadline. Penalties apply; late filings accrue interest at 8% annually.
- Not getting an A1 certificate when working in Poland for a foreign employer.
Practical Checklist for Foreign Remote Workers in Poland
- Determine your tax residency status (days + vital interests test)
- Identify the applicable double taxation treaty
- Gather foreign tax certificates by March each year
- Choose correct PIT form (PIT-36, PIT-36L, or PIT-28)
- File by April 30
- Check social security status — obtain A1 if needed
- Consider registering a JDG if working for multiple foreign clients
