Bossa vs XTB IKE — The Battle for Poland's Best Retirement Account
Bossa (Dom Maklerski BOŚ) and XTB are two of the strongest IKE providers on the Polish brokerage market, offering tax-advantaged retirement accounts with access to local and international instruments.
IKE is Poland's tax-advantaged retirement account — similar in spirit to a Roth IRA in the US or an ISA in the UK. Gains are entirely free of the 19% Belka tax if you withdraw after age 60 (or 55 with pension rights), having contributed in at least 5 calendar years. Over a 20-30 year horizon the tax savings can amount to tens of thousands of złotys.
Quick Answer
For most passive ETF investors, XTB IKE is the cheaper account: 0% commission on stocks and ETFs up to €100,000 of monthly turnover, fractional shares, and 1,000+ ETFs — the main cost is the 0.5% FX fee on foreign-currency trades. Bossa IKE wins for investors who also want Catalyst bonds, NewConnect, and the full GPW toolkit under one roof: GPW trades cost 0.38% (min 5 PLN), foreign markets 0.29% (min 14 PLN / 4 EUR / 4 USD for the US, Germany and the UK), and bonds just 0.19% (min 5 PLN). Both accounts are free to maintain with e-statements and both brokers also offer IKZE. The 2026 IKE contribution limit is 28,260 PLN (IKZE: 11,304 PLN, or 16,956 PLN for the self-employed).
The 2026 Limits
| Parameter | Value (2026) |
|---|---|
| IKE annual contribution limit | 28,260 PLN |
| IKZE annual limit | 11,304 PLN (16,956 PLN self-employed) |
| IKE tax benefit | 0% Belka tax on gains at qualified withdrawal (age 60/55, 5 contribution years) |
| IKZE tax benefit | Contributions deductible from income; flat 10% tax at withdrawal (age 65) |
| Accounts allowed | One IKE and one IKZE per person |
You can transfer an IKE between institutions free of tax — the transfer itself is not a withdrawal.
Fees Compared (verified September 2026)
| Fee | Bossa IKE | XTB IKE |
|---|---|---|
| Account maintenance | 0 PLN (with e-access) | 0 PLN |
| GPW stocks/ETFs | 0.38% (min 5 PLN) online | 0% up to €100k/month turnover (0.2% min €10 above) |
| Foreign stocks/ETFs | 0.29% (min 14 PLN / 4 EUR / 4 USD for US, DE, UK) | 0% up to €100k/month turnover |
| Bonds (Catalyst) | 0.19% (min 5 PLN) | not available |
| FX conversion | embedded in execution | 0.5% |
| Inactivity fee | none | none inside IKE |
The economics: on a 1,000 PLN monthly GPW ETF purchase, Bossa costs 5 PLN (the minimum) and XTB costs 0 PLN. On foreign UCITS ETFs, XTB's 0% commission comes with a 0.5% FX conversion (~5 PLN per 1,000 PLN), while Bossa charges its 14 PLN minimum — so for small recurring foreign buys XTB is cheaper, and the gap narrows for large orders.

- XTB IKE: 3,500+ stocks across 16 exchanges, 1,000+ UCITS ETFs, fractional shares, Polish Beta ETFs. No bonds, no options, no futures.
- Bossa IKE: full GPW access (including NewConnect), Catalyst corporate and treasury bonds, foreign markets (US, Western Europe), and — outside the IKE wrapper — derivatives (index futures 9.90 PLN/contract).
If your retirement portfolio is "global ETF + maybe some GPW dividend stocks", XTB covers everything at lower cost. If you want Catalyst bonds or NewConnect small-caps inside your IKE, Bossa is the one that can hold them.
Platforms
- Bossa: bossaWebTrader (browser) and the NOL3 desktop terminal — powerful, dated-looking, deep GPW market data.
- XTB: xStation 5 (web, desktop, mobile) — widely considered one of the most polished retail platforms in Europe, with built-in fractional buying and investment plans.
Taxes and Reporting
Inside an IKE, nothing is reported annually — no PIT-38, no Belka tax on rebalancing, dividends from Polish instruments accrue without annual settlement. At qualified withdrawal (age 60, or 55 with early pension rights, plus contributions in 5 calendar years), the entire gain is tax-free. Note that foreign dividends still suffer withholding at source (e.g. 15% US with W-8BEN) — an argument for accumulating UCITS ETFs inside the wrapper.
Both brokers also offer IKZE (XTB added it in mid-2025), where contributions reduce your taxable income now in exchange for a flat 10% tax at withdrawal after 65.
Which Should You Choose?
Choose XTB IKE if:
- You DCA into UCITS ETFs monthly (0% commission + fractional shares)
- You want one polished app for IKE, IKZE and a regular account
- You value the simplest possible cost structure
Choose Bossa IKE if:
- You want Catalyst bonds or NewConnect names inside the wrapper
- You are primarily a GPW investor comfortable with a classic brokerage platform
- You already use DM BOŚ for an active trading account
Many investors simply choose based on where the rest of their investing lives — both are KNF-regulated, both keep securities registered at KDPW in your name, and both are covered by the Polish investor-compensation scheme (100% of the first €3,000 plus 90% of the excess, up to roughly €22,000).
FAQ
What is the IKE contribution limit for 2026?
28,260 PLN (three times the projected average monthly wage). The IKZE limit is 11,304 PLN, or 16,956 PLN for the self-employed.
Can I have both an IKE and an IKZE?
Yes — one of each, and they can be at different institutions. Maxing both shelters roughly 40,000 PLN of contributions per year.
Can I move my IKE from Bossa to XTB (or the other way)?
Yes. An IKE transfer between institutions is free of tax and does not count as a withdrawal. The receiving broker handles the paperwork; allow a few weeks.
What happens if I withdraw before 60?
A full early withdrawal (zwrot) triggers 19% Belka tax on the gains — you lose the shelter but not your capital. Partial early withdrawals are possible on IKE (not IKZE), also taxed.
Is my money safe at these brokers?
Securities are registered at KDPW in your name and are returned to you even if the broker fails. Cash is covered by the Polish investor-compensation scheme: 100% of the first €3,000 and 90% of the excess, up to roughly €22,000 equivalent.
