IKE or IKZE — which one to choose?

If you pay income tax and save until 65, in our examples the combination of both accounts gives the most: you pay into an IKZE and put its tax refund into an IKE. If you save PLN 500 a month for 30 years and your investments earn 7% a year, IKZE + IKE gives more than an IKE alone: PLN 8,267 more on a gross salary of PLN 8,000 (12% rate), PLN 123,711 more on a gross salary of PLN 15,000 (32% rate) and PLN 48,673 more with a business on the 19% flat tax. In our examples an IKE alone comes out ahead if you pay no income tax or take the money out at 60–64.

How do IKE and IKZE differ?

An IKE (Indywidualne Konto Emerytalne, individual retirement account) and an IKZE (Indywidualne Konto Zabezpieczenia Emerytalnego, individual retirement security account) are Polish accounts for retirement savings with a tax break. Banks, brokerage houses, investment funds and insurers, among others, run them. You can have at most one IKE and one IKZE, and both at once. The key difference: an IKZE gives you the tax relief when you pay in, an IKE when you take the money out.

The limits are per calendar year and each account has its own, so in 2026 you can pay up to PLN 39,564 into the two together (PLN 45,216 if you run a business). They are worked out every year from the forecast average monthly wage: the IKE limit is three times that wage, the IKZE limit 1.2 times (1.8 times for a business). The next year's limits are announced at the end of the current one. You can pay in any amount whenever you like, as long as you stay within the limit.

How do IKE and IKZE cut your tax?

You pay into an IKE out of money you've already paid tax on, and get no relief for it. The benefit comes when you take the money out: once you meet the conditions in the table, you don't pay the 19% podatek Belki (Belka tax, Poland's capital gains tax) on the gain. If you save PLN 500 a month for 30 years at a 7% yearly return — the numbers we use throughout this guide — you'll pay PLN 81,697 in tax in an ordinary brokerage account, and nothing in an IKE.

With an IKZE the relief comes straight away: you deduct the year's contributions from your income in your annual tax return. The refund is the tax this saves you: 12% of your contributions in the first bracket of the tax scale, 32% in the second (on income above PLN 120,000 a year), and 19% on the flat tax. It can't be more than the tax you pay, though, and on the scale the first PLN 30,000 of income a year is in effect tax-free, so deducting from that part gains you nothing. On PLN 500 a month, or PLN 6,000 a year, the refund is PLN 720 on a gross salary of PLN 8,000 (12% rate), PLN 1,920 on a gross salary of PLN 15,000 (32% rate) and PLN 1,140 with a business on the 19% flat tax.

The relief has a price. From age 65, if you've paid in during at least 5 calendar years, you pay 10% tax on the whole withdrawal — on your contributions and on the gain. An IKZE works like a tax deferral: now you save 12%, 32% or 19% of what you pay in, and on withdrawal you hand over 10% of everything you've built up.

Which gives more: an IKE or IKZE + IKE?

We work it out the way our IKE, IKZE and PPK calculator does. You start at 35, put away PLN 500 a month out of your own pocket and take everything out at 65. Every account earns 7% a year. We compare three options:

• an ordinary brokerage account: on withdrawal you pay 19% Belka tax on the gain;
• an IKE alone: a tax-free withdrawal;
• IKZE + IKE: you pay into the IKZE every month, and put each year's tax refund into the IKE in April of the following year. The last year's refund only arrives after the withdrawal, so we count it as cash.

The only thing we change is how you earn: two gross salaries and the monthly income of a business on the flat tax. This is what you're left with after every tax:

The ordinary account and an IKE alone don't depend on what you earn. Only IKZE + IKE changes, because the tax refund depends on your income tax rate. At the 12% rate, though, the lead is small compared with the whole amount: PLN 8,267, about 1.4% of what an IKE alone gives. In return the IKZE money only comes out with the relief from 65, and you have to put every tax refund into the IKE; if you take the money out at 64, an IKE alone gives PLN 108,213 more.

Why does an IKZE pay more on a higher tax rate?

In the IKZE + IKE option the IKZE gets the same amount every month as the IKE gets in the IKE-alone option, and grows the same way. Two things differ: on withdrawal you pay 10% tax on the whole IKZE amount, and every year you get a tax refund, which goes into the IKE and keeps earning there. IKZE + IKE wins when the refunds, with what they earn, are worth more than that tax.

The tax on withdrawal is the same in every example — PLN 60,999 — because the same money goes into the IKZE. The refunds, though, follow your tax rate: at the 12% rate they grew to PLN 69,266, and at the 32% rate to PLN 184,709.

The tax refund only works for you if you save it. If you spend it, the IKZE alone leaves you 10% less on withdrawal than an IKE with the same contributions — PLN 60,999 less in our example. A refund you spend means lower tax today, but not a bigger pension.

What if you take the money out early?

Until you meet the conditions in the table above — the age and the years of contributions — you can only take the money out as a zwrot (an early payout), and you lose the relief. From an IKE you pay 19% tax on the gain — the same as in an ordinary account. From an IKZE the whole amount is added to that year's income and taxed on the scale: once it takes your scale income above PLN 120,000, you pay 32% on the excess. It's taxed on the scale even if your business pays the flat tax.

This is how our examples look with an earlier withdrawal:

If you take the money out at 64, the IKE is already tax-free, but the whole IKZE amount is added to your income and taxed on the scale. An IKE alone gives more than IKZE + IKE: PLN 108,213 more at the 12% rate, PLN 9,676 more at the 32% rate and PLN 51,346 more on the flat tax.

If you take the money out at 59, both accounts pay out a zwrot: you pay 19% tax on the IKE's gain, and the whole IKZE amount is taxed on the scale. IKZE + IKE gives more than an IKE alone by PLN 24,286 at the 32% rate and by PLN 11,261 on the flat tax, while an IKE alone gives more than IKZE + IKE by PLN 30,182 at the 12% rate.

Like the calculator, we assume you still earn the same salary in the year you take the money out, so the IKZE payout is added on top of it. If you've stopped working by then, the tax on it is lower and the result can flip, especially on a high salary.

What decides it is whether the tax refunds with their growth outweigh the difference in tax on withdrawal. If you might need the money before 65, an IKE alone is the safer choice: it never comes out worse than an ordinary account, and from age 60 you take everything out tax-free.

What to hold in an IKE and an IKZE?

It depends on the institution that runs the account. At a bank it's a savings account or deposits, at an investment fund its units, at a brokerage house shares, ETFs and bonds, and at an insurer a unit-linked insurance policy. Polish treasury savings bonds, including EDO and COI, can be held in the IKE-Obligacje and IKZE-Obligacje accounts at PKO Bank Polski. You can move an account to another institution, so your first choice isn't for ever.

An IKE spares you the tax on the gain, so the bigger the gain, the more the relief is worth. In our example, at a 7% yearly return an IKE gives PLN 81,697 more than an ordinary account, and at 4% PLN 31,735 more. So it does the most for investments you expect to earn the most, such as equity funds or ETFs — as long as you can live with their ups and downs. Our calculator assumes 7% a year, roughly the historical average of a global equity portfolio, and leaves out fees, so compare them before you choose an institution. We cover bonds in an IKE in the guide EDO or COI, and you can see how a regular contribution grows at different rates of return in the compound interest calculator.

IKE, IKZE or both — and what about OKI?

You don't have to pick one account. If you pay income tax and are saving for retirement rather than for spending before 65, in our examples the IKZE + IKE order works best: fill the IKZE limit first, then put the tax refund and the rest of your savings into the IKE. In the same examples an IKE alone pays more if you pay no income tax or plan to take the money out at 60–64. The 5-year contribution condition is easier to meet if you start early, even with small amounts. If you're an employee, you can also save in PPK, the workplace pension scheme — we work out whether it's worth staying in it in the guide Is PPK worth it?

From January 1, 2027, you can also save in an OKI (Osobiste Konto Inwestycyjne, personal investment account). It's a separate account that anyone aged 18 or over can open. Income from the assets in an OKI isn't subject to the Belka tax. Instead, there's a yearly tax on the average value of the assets above the exemptions, which in 2027 are: up to PLN 25,000 for savings assets such as złoty cash and treasury savings bonds, and up to PLN 100,000 in total together with złoty instruments, such as złoty bonds or shares of companies with their capital in złoty. Foreign shares and most global ETFs get no exemption. The rate for 2027 is 0.85%, and from 2028 it's 19% of the NBP reference rate on October 31 of the year before, but no less than 0.1%. There's more on OKI in our guide to the Belka tax.
