The individual retirement security account, IKZE (Indywidualne Konto Zabezpieczenia Emerytalnego), is mainly associated with saving for retirement. For someone running a sole proprietorship, however, it is also one of the few fully legal tools that let you reduce your tax for the current year without incurring any business expense. The money still belongs to you — it is simply set aside for later. Because contributions made in a given calendar year are what counts, autumn is the last good moment to consider this relief for the 2026 settlement.
A higher contribution limit for people running a business
The annual IKZE contribution limit is set every year on the basis of the forecast average wage. According to the announcement of the minister responsible for social security dated 10 November 2025, in 2026 it amounts to PLN 11,304 for most savers and PLN 16,956 for people running non-agricultural business activity. The higher limit equals 1.8 times the forecast average wage, the standard one — 1.2 times.
For an entrepreneur, this means being able to set aside more than PLN 5,600 more than a person employed solely under an employment contract. The limit applies to the total contributions in a calendar year, not to each individual payment — you can pay in a lump sum or in any instalments. If your business was suspended during the year or you are just starting out, it is worth confirming with the account provider which limit will apply before making a large contribution.
Deduction under the tax scale, flat tax and lump-sum tax
IKZE contributions are deducted in the annual tax return, and how they are settled depends on your form of taxation. Under the progressive tax scale and the flat tax, contributions reduce income, while under the lump-sum tax on recorded revenue (ryczałt) they reduce revenue. The deduction is shown in the PIT-36, PIT-36L or PIT-28 return, using the relevant schedule of deductions.
There is one limitation to bear in mind: if your income or revenue in a given year turns out to be too low to deduct the entire contribution, the unused part cannot be carried forward to subsequent years. That is why it is best to match the contribution to the expected business result rather than paying in "just in case".
How much you can actually save
Put simply, the tax saving is the contribution multiplied by the rate that applies to your income or revenue. With the full limit of PLN 16,956, an entrepreneur taxed under the scale in the second bracket (32%) can reduce tax by about PLN 5,426, and in the first bracket (12%) by about PLN 2,035. Under the 19% flat tax, the benefit is about PLN 3,222. Under the lump-sum tax, the saving depends on the rate — at 12% it is about PLN 2,035, at 8.5% about PLN 1,441.
These are indicative amounts, calculated on the assumption that the entire contribution fits within income or revenue taxed at the given rate. In practice, it is worth running the numbers on your own figures — especially when your income is close to a tax bracket threshold or when you use other reliefs.
Deadline: the payment must be made in the tax year
For a contribution to reduce tax for 2026, it must be made in 2026. It cannot be "sent later" in January or when filing the return, as is possible in some countries. The last days of December are a period of holiday breaks at banks and financial institutions, so it is safer to order the transfer a few days in advance and keep the confirmation.
Before paying in, you need to have an IKZE account opened — they are offered by, among others, banks, brokerage houses, investment fund companies and insurance companies. You can have only one IKZE, but you can transfer it to another institution without losing the relief. When choosing a provider, pay attention to the fees and how the money is invested, as these determine how much actually remains in the account over the years.
What happens at withdrawal
The relief has another side: funds from an IKZE are taxed on withdrawal. If you withdraw them after turning 65 and meet the statutory conditions regarding the contribution period, you pay a flat 10% tax on the amount withdrawn. In the case of an earlier return of funds, the entire amount is added to your revenue and taxed under general rules, and the relief effectively stops paying off.
This is why an IKZE works best as a long-term part of a retirement plan rather than as a way to park surplus cash for a short time. For many entrepreneurs who pay contributions on the minimum base for years, it is also a real way to top up their future pension from ZUS (the Polish Social Insurance Institution).
