Foreign Dividend Tax in Poland -- How to File

Why Foreign Dividends Need Special Attention

If you invest in American, German, or Irish stocks, your dividends are taxed twice -- first in the source country, then in Poland. Fortunately, double taxation treaties (DTTs) allow you to minimize this burden.

This affects a growing number of Polish investors. Popular S&P 500 ETFs, dividend stocks from NYSE, European blue chips -- all generate foreign dividends that you must report yourself.

How Double Taxation Works

The Mechanism:

1. Source country withholds tax from the dividend
2. Poland applies 19% capital gains tax on the same income
3. Credit method allows you to offset tax paid abroad

Withholding Tax Rates (Most Common Countries):

Step-by-Step: Filing US Dividends

US dividends are the most common case for Polish investors (Apple, Microsoft, S&P 500 ETFs).

Step 1: Submit W-8BEN Form

Before receiving your first dividend, submit a W-8BEN form through your broker. This reduces the US withholding tax from 30% to 15% under the Poland-US tax treaty.

Important: W-8BEN is valid for 3 years -- remember to renew it.

Step 2: Receive the Dividend

Example: You own 100 shares of Microsoft, dividend is 3 USD per share.

• Gross dividend: 300 USD
• US withholding tax (15%): 45 USD
• Net dividend received: 255 USD

Step 3: Convert to PLN

Convert the dividend to PLN using the average NBP exchange rate from the business day before you received the dividend.

Assuming USD/PLN = 4.05:

• Gross dividend: 300 x 4.05 = 1,215 PLN
• Tax paid in the US: 45 x 4.05 = 182.25 PLN

Step 4: Calculate Polish Tax

• Polish tax due: 1,215 x 19% = 230.85 PLN
• Credit for US tax paid: 182.25 PLN
• Amount to pay in Poland: 230.85 - 182.25 = 48.60 PLN

Total tax burden: 182.25 + 48.60 = 230.85 PLN, effectively 19% -- the same as for Polish dividends.

Step 5: File on PIT-38

On PIT-38, in the foreign income section, report:

• Foreign dividend income (in PLN)
• Tax paid abroad (in PLN)
• Net tax due after credit

Tricky Cases

Ireland -- UCITS ETFs

Most European ETFs are domiciled in Ireland. Irish withholding tax on dividends paid to Polish residents is 15% under the DTT. Report the same way as US dividends.

But note: accumulating ETFs domiciled in Ireland don't distribute dividends -- they reinvest automatically. This means you avoid current dividend taxation entirely.

Germany -- Excess Withholding Problem

Germany withholds 26.375% (Kapitalertragsteuer + Solidaritatszuschlag). The DTT only allows you to credit 15% on your Polish PIT. The excess (11.375%) can be reclaimed by filing with the German tax office (Bundeszentralamt fur Steuern) -- but the process takes 6-12 months.

United Kingdom -- The Ideal Jurisdiction

The UK charges 0% withholding tax on dividends paid to non-residents. You only pay the Polish 19% -- the simplest scenario.

Switzerland -- The 35% Problem

Switzerland withholds 35% on dividends. The DTT limits the credit to 15%. You can reclaim the excess 20% from the Swiss tax authority, but the process is slow and bureaucratic.

Dividends on IKE/IKZE Accounts

If you invest in foreign dividend stocks on IKE, the source country withholding tax (e.g., 15% in the US) is still deducted. You cannot reclaim or credit it. However, Polish capital gains tax is waived on IKE.

This means for IKE accounts, it's optimal to hold:

• Accumulating ETFs (avoid foreign withholding tax on dividends entirely)
• Polish dividend stocks (no double taxation issue)

For IKZE, the same logic applies -- accumulating ETFs are more tax-efficient than distributing ones.

How to Simplify Dividend Tracking

Investing in foreign stocks across multiple platforms (XTB, Revolut, Interactive Brokers) makes dividend tracking complex. Freenance integrates with popular banks and brokers, showing your complete investment picture -- including dividends -- and their impact on your Financial Freedom Runway.

Tax-Efficient Dividend Strategy

Based on the tax implications, here's an optimal approach:

On IKE (tax-free gains):

• Accumulating global ETFs (e.g., VWCE)
• Polish dividend stocks (no foreign withholding)

On regular brokerage account:

• UK stocks (0% withholding)
• US stocks with W-8BEN (15% withholding, fully creditable)

Avoid on IKE:

• Distributing ETFs from high-withholding countries
• Swiss dividend stocks (35% withholding, non-recoverable on IKE)

Common Mistakes

1. No W-8BEN filed -- you pay 30% instead of 15% on US dividends
2. Forgetting to report -- your broker doesn't do it for you
3. Wrong NBP exchange rate -- use the rate from the day before receipt
4. Crediting more than allowed -- you can credit at most the Polish tax amount on that income
5. Not reporting small dividends -- even a 5 USD dividend must be declared
6. Expired W-8BEN -- check the expiry date and renew proactively

Summary

Filing foreign dividend taxes requires extra work but follows a clear process:

• Submit W-8BEN for US investments
• Convert to PLN using the NBP rate from the preceding business day
• Credit foreign tax paid using the credit method
• File PIT-38 by April 30
• Consider accumulating ETFs on IKE -- avoid double taxation entirely

The most tax-efficient approach for Polish investors: use accumulating Irish-domiciled ETFs on your IKE account. This eliminates both the foreign withholding tax and the Polish capital gains tax -- the best of both worlds.

FAQ

Do I need to report foreign dividends on PIT-38 in Poland?

Yes — Polish tax residents must self-report all foreign dividend income on the annual PIT-38, including the amount withheld abroad. Your broker does not file Polish taxes for you, and missing even small dividends can trigger penalties on audit.

What is W-8BEN and why is it important?

The W-8BEN is a US tax form that certifies you are a non-US resident eligible for treaty benefits, reducing US withholding tax on dividends from 30% to 15% under the Poland-US treaty. You submit it once through your broker, and it must be renewed every three years to keep the lower rate in effect.

Which NBP exchange rate do I use for foreign dividends?

You convert each dividend to PLN using the average NBP exchange rate from the last business day before the dividend was credited to your account. The same rate is used to convert the foreign tax paid, so that both amounts are expressed in PLN on PIT-38.

Can I credit the full foreign tax against my Polish dividend tax?

You can credit at most the lower of the foreign tax actually paid and the Polish tax due on that dividend (19% of the gross amount). Any excess — for example, the extra 11.375% withheld in Germany or 20% in Switzerland — must be reclaimed from the foreign tax authority directly, not in Poland.

Are dividends on IKE and IKZE tax-free in Poland?

Yes, Polish capital gains tax is waived on IKE and IKZE, including dividends received inside those accounts. However, the foreign source country still withholds its share at the local rate, and you cannot credit or reclaim that withholding through your Polish return — which is why accumulating ETFs are typically the most tax-efficient choice on these accounts.
