OKI vs IKE vs IKZE: What to Choose in 2026? Taxes, Limits, and Calculations for 2027

OKI, or Personal Investment Account, does not replace IKE or IKZE. The new account addresses a different issue: it will allow investments and withdrawals without waiting until retirement age, but after exceeding the statutory exemptions, it will convert the 19% income tax into an annual tax on the average value of assets. It is often presented as a tax-free investment account, although in practice it will not be unconditionally free of tax.

Therefore, the question "OKI vs IKE vs IKZE -- which account is the best?" is poorly phrased.

A better question is: which funds should be available earlier, which are saved for retirement, and from which assets will we actually receive relief?

In this guide, we break down all three accounts into their components. We also show specific models for different incomes, portfolio values, and rates of return, including a loss scenario. Table of Contents:

OKI from 2027: the law has already been announced {#1}

Important update: OKI is no longer a project waiting for a signature. The President signed the law on August 13, 2026, and on August 18, it was announced as Journal of Laws of 2026, item 1098.

The entire law on personal investment accounts comes into force on January 1, 2027.

OKI is therefore a certain future law, but not yet an operational account.

The law does not require every bank or brokerage house to launch an offer on the first day. We also described the current stage of work in the CrypS.pl news about the President signing the OKI law.

What is OKI and how will it work? {#2}

Personal Investment Account will be a voluntary tax wrapper for individuals who are over 18 years old.

Accounts can be maintained by, among others, domestic banks, authorized brokerage entities, investment funds, voluntary pension funds, and appropriate insurance companies.

The law allows a wide range of assets, including:

• money in bank and brokerage accounts,
• retail treasury bonds,
• units of investment funds, UFKs, and voluntary pension funds,
• stocks, bonds, and other securities meeting market or public offering conditions,
• certain money market instruments.

The actual list of available instruments will depend on the institution.

The law does not cover direct bitcoin, ether, or other crypto-assets.

A stock product providing exposure to cryptocurrencies will need to be assessed separately for its structure, market, and eligibility for exemption.

The law allows certain assets and cash in PLN and in currencies of EU, EEA, and OECD countries.

The actual selection will also depend on the institution's offer. This does not mean that every foreign stock or every global ETF will receive a preference up to 100,000 PLN.

Allowing assets into the account and the right to exemption are two different things.

Withdrawals from OKI without waiting for retirement {#3}

OKI does not have a statutory withdrawal age or minimum savings period. Money can be withdrawn in full or partially.

However, the timing of a regular withdrawal will be determined by the agreement with the institution, so the term "immediate access" may be too far-reaching.

This flexibility distinguishes OKI from IKE (Individual Retirement Account) and IKZE (Individual Retirement Security Account).

The price is the tax structure: after exceeding the exemption, tax may arise even if the portfolio ends the year at a loss.

How does the tax on OKI work? The limit of 100,000 PLN has three hooks {#4}

Income generated within OKI is excluded from Polish PIT by law.

Instead of income tax, there is a tax on the value of assets. The basis is the sum of average values from all OKIs of the taxpayer, calculated from daily valuations. Therefore, only the balance on December 31 is not included.

In simplified terms, the portfolio is divided into three baskets:

• S -- average value of qualified savings assets,
• I -- average value of qualified investment assets,
• N -- average value of other OKI assets without the right to exemption.

The mechanism can be summarized in three steps. First, up to 25,000 PLN is exempted from the savings basket.

Next, qualified investments benefit only from that part of the total threshold of 100,000 PLN that was not utilized by savings.

The remaining part of both baskets and the entire value of assets without the right to exemption goes to the tax base.

Hook #1: 25,000 PLN does not add to 100,000 PLN

The maximum total exemption is 100,000 PLN, not 125,000 PLN.

Moreover, the excess of the savings part over 25,000 PLN cannot be covered by unused space in the investment basket.

The amounts in the table are already average annual values, not contributions or ending balances. According to the OKI Act for 2027, the rate is 0.85%.

From 2028, it is to correspond to 19% of the NBP reference rate from October 31 of the previous year, not less than 0.1%.

The law does not establish a maximum rate. The first increase in exemption amounts of 25,000 and 100,000 PLN will occur from 2030.

Hook #2: Foreign instruments may be taxed from the first zloty

Preference for direct shares includes securities of companies whose share capital is denominated in zlotys.

In the case of funds and other similar products, the right to exemption depends, among other things, on the statutory category of the product and the exposure to qualified assets recorded in its investment policy.

For many such products, the threshold is at least 70%.

This means that a popular global ETF or a share of an American company may be available on OKI, but its average value may enter the tax base from the first zloty.

One should not qualify a product solely based on its name, the currency of quotation, or the fact that it is an ETF.

Catch #3: Tax May Occur Despite Loss

The OKI agreement must include a statement from the investor that they understand two consequences: assets may be subject to tax even in a year of loss, and the loss itself will not be a tax loss in PIT.

On a regular account, the tax on realized income is generally 19%.

When a sale results in a loss, there is no current tax, and the loss can be carried forward in subsequent years according to PIT rules.

For OKI, the mechanism is different: the average value of the taxable part of the portfolio is counted.

Settlement of OKI in the e-Tax Office {#5}

Institutions will provide the tax office with information by the end of February of the following year.

The law provides for the availability of data in the e-Tax Office and the submission of declarations exclusively electronically from March 15 to May 31. The tax must be paid by May 31. The first such settlement, for the year 2027, will occur in 2028.

The law also creates a mechanism for automatic acceptance of correctly completed documents upon the expiration of the deadline.

However, it should not be assumed that every OKI settlement will be sent automatically: the catalog of covered documents and exceptions will result from implementing regulations. Automatic acceptance of the declaration does not replace timely payment, so it is advisable to check the status of the document and the amount in the e-Tax Office before May 31.

Will OKI be free? {#6}

There is no such guarantee. The law allows for costs and fees to be charged as specified in the agreement, regulations, statute, or general terms of the product.

When comparing future offers, one should check transaction commissions, currency conversion costs, asset storage fees, fund costs, and the conditions for transfer and withdrawal.

IKE in 2026: No Entry Relief, No Belka on Exit {#7}

Individual Retirement Account is a tax wrapper, not a specific investment.

It can take the form of a brokerage account, fund account, bank account, insurance account, or account in a voluntary pension fund.

What can be purchased depends on the chosen provider.

The contribution limit for IKE in 2026 is 28,260 PLN, as confirmed by MRPiPS.

Unused parts of the limit do not carry over to the next year.

A transfer from one IKE to another is not a new contribution and does not consume the limit if it follows the path specified in the IKE and IKZE law.

When is a withdrawal from IKE tax-free? {#8}

According to the IKE and IKZE law, in a typical case, two types of conditions must be met:

1. reach 60 years of age or complete 55 years and acquire retirement rights,
2. contribute to IKE in at least five calendar years or contribute more than half of the total value of contributions no later than five years before submitting the application.

There are important exceptions to this rule. The five-year test does not apply to funds transferred from an employee pension program (PPE).

For individuals born before December 31, 1945, the law retains a three-year test, and for those born from January 1, 1946, to December 31, 1948, a four-year test.

Details arise from Article 34, paragraph 1a, and Article 46 of the law.

Upon meeting the conditions, a one-time or installment withdrawal is exempt from Polish capital gains tax.

What about early withdrawal of funds from IKE? {#9}

IKE is more flexible than IKZE. A full or partial withdrawal is possible, with partial withdrawals coming from the investor's own contributions to IKE. An early withdrawal incurs a 19% tax on the legally calculated income, not on the entire withdrawal.

Example: if a total of 80,000 PLN was deposited into IKE, and the account is worth 100,000 PLN, the simplified tax on 20,000 PLN of profit amounts to 3,800 PLN. Special rules apply to funds previously transferred from PPE.

Individual Retirement Security Account is also a tax wrapper. Its main benefit is the ability to deduct contributions:

• from income taxed at a progressive rate,
• from income taxed at a 19% flat tax,
• from revenue taxed under a lump-sum tax on registered income.

According to the Ministry of Finance, the limit in 2026 is 11,304 PLN or 16,956 PLN for individuals conducting non-agricultural business as defined by the Social Insurance System Act.

The higher limit covers a broader group than commonly understood JDG, but it should not be automatically granted to every person issuing invoices.

The deduction is reported in the annual tax return. It does not reduce current advance payments, and any unused portion due to insufficient income or revenue cannot be carried over to subsequent years.

When can IKZE be withdrawn under preferential terms? {#11}

According to the IKE and IKZE Act, it is necessary to reach 65 years of age and to have made contributions for at least five calendar years.

The withdrawal can be either one-time or in installments.

Installments are generally spread over at least 10 years, and for a shorter contribution period, they can be spread over as many years as contributions were made.

Preferential withdrawal is taxed at 10% on the entire amount received, not just on the profit. This is the most significant difference compared to IKE.

Early withdrawal from IKZE may fall into the 32% tax bracket {#12}

IKZE does not allow for partial withdrawals. Before meeting the conditions, only the total amount can be withdrawn, and according to the PIT Act, the returned amount becomes income from other sources taxed at the progressive rate.

This also applies to entrepreneurs who previously deducted contributions under the flat tax or lump-sum tax.

Let’s assume that IKZE is worth 100,000 PLN, and the taxpayer has 80,000 PLN of other income taxed at the progressive rate in the year of withdrawal. In a model without other deductions, the withdrawal increases PIT by 24,000 PLN.

A qualified withdrawal of the same amount would mean 10,000 PLN in tax. The difference is 14,000 PLN, although the full benefit calculation should also consider the deductions received during the contribution years.

OKI vs IKE vs IKZE -- comparison of rules {#13}

None of the accounts guarantee profit. The risk of the instrument, fees, currency spread, and withholding tax may be more important than the name of the package itself.

How to select asset classes and horizons is described in the CrypS.pl guide on how to build an investment portfolio.

How much can you deduct with IKZE? Examples for different incomes {#14}

You cannot multiply the IKZE contribution by the rate assigned to gross salary.

What matters is the taxable base after costs, contributions, and other deductions, and joint filing and other incomes may also be significant.

The following model uses the PIT scale applicable in 2026: 12% up to 120,000 PLN base, a tax-reducing amount of 3,600 PLN, and 32% on the excess over 120,000 PLN.

We assume a full standard IKZE contribution of 11,304 PLN, no other deductions, and we ignore final rounding of the declaration.

At a base of 125,000 PLN, only 5,000 PLN of the deduction reduces the taxed portion at 32%, while the remaining 6,304 PLN is taxed at 12%. Therefore, the benefit is 2,356.48 PLN, not 3,617.28 PLN.

For a person entitled to a limit of 16,956 PLN, the maximum mechanical effect is:

• 2,034.72 PLN at the 12% rate,
• 3,221.64 PLN at the linear tax of 19%,
• 5,425.92 PLN if the entire contribution reduces the taxable base at 32%.

Full utilization of these values requires a sufficient taxable base or income.

In the case of a lump sum, the result also depends on the rate. If the business has several lump sum rates, deductions cannot be arbitrarily assigned to the highest one.

How much can you save or lose on OKI? {#15}

Let’s compare 2027 for capital deposited on January 1 and a smooth geometric path that gives 7% growth by the end of the year.

OKI is settled based on the average of 365 daily values. The usual calculation assumes full sale on December 31 and a 19% tax on realized profit. We ignore fees, dividends, withholding tax, and rounding of declarations.

A 100,000 PLN Portfolio Demonstrates the Role of Average Value. The portfolio starts at the threshold of exemption, but during growth, its average rises to approximately 103,470 PLN. Therefore, the tax on the qualified surplus amounts to 29.50 PLN.

The most important caveat: if we do not sell the appreciating asset in a regular account, and the instrument does not make distributions, the unrealized price increase does not yet generate tax. Dividends, interest, and rebalancing can change this picture. OKI settles tax on value annually, so a regular account can be competitive for an investor buying an accumulating asset and postponing sales for many years.

A 250,000 PLN Portfolio: From Loss to 10% Profit {#16}

Below, we maintain the same model but change the annual rate of return. The assets are qualified investments, so the first 100,000 PLN of average value benefits from the exemption.

In this purely illustrative, annual model, the break-even point for 250,000 PLN of qualified assets falls around a 2.7% return. For assets without any exemption, the simple ratio of rates 0.85% and 19% is about 4.47%, but considering the higher average value of the growing portfolio shifts the exact break-even point in the same model to about 4.58%. These are not universal profitability thresholds: the result is affected by average value, timing of contributions, sales or lack thereof, fees, dividends, losses, and foreign taxes.

IKE or IKZE? A 20-Year Model {#16}

Let’s assume 20 annual contributions of 11,304 PLN at the beginning of the year and a constant 5% nominal rate of return.

Total contributions amount to 226,080 PLN. We ignore fees, inflation, withholding tax, and changes in law. The regular account sells everything only at the end.

• gross value of the portfolio, and thus qualified withdrawal from IKE: 392,466 PLN ,
• regular account after 19% tax on the final profit: 360,853 PLN ,
• advantage of IKE over the regular account: 31,613 PLN ,
• IKZE after 10% tax on the entire withdrawal: 353,220 PLN , before adding benefits from deductions obtained over 20 years.

The last number shows why one should not compare IKE and IKZE solely based on the balance. IKZE performs worse at the very end, but earlier returns part of the PIT.

What if the PIT Return from IKZE is Reinvested? {#17}

In another variant, the household allocates 11,304 PLN of its own funds each year.

11,304 PLN goes to IKE. 11,304 PLN also goes to IKZE, and the equivalent of the PIT benefit obtained is added to the regular account on March 31 of the following year.

The profit from this side account is subject to a 19% tax upon final sale.

The valuation is due on December 31 of the year 20, therefore it includes 19 annual tax benefits from IKZE, the benefit for the year 20 will only appear after this date. The actual deadline depends on the submission and settlement of the tax return.

The model shows four things:

• IKZE is particularly strong with a high effective deduction rate.
• Reinvesting the PIT return is crucial. If the return is spent, it will not be in the final portfolio, although it still represents a current consumption benefit.
• The timing of receiving benefits also matters. At a rate of 12%, the advantage over IKE in this variant is only about 456 PLN and may disappear with later refunds.
• The result is not a forecast. A constant 5% over 20 years and unchanged regulations are technical assumptions.

One can also compare the same nominal cost after annual tax settlement without reinvesting the PIT return.

For simplicity, we assign the benefit to the year of contribution and ignore the delay between the transfer to IKZE and the PIT settlement.

These are not identical cash flows realized on the same days.

IKZE receives 11,304 PLN, while the contribution to IKE is lower by the value of the tax benefit, which the IKE holder does not receive.

With 5% over 20 years, IKZE after tax yields about 353,220 PLN, while IKE yields approximately about 345,370 PLN with a tax benefit of 12%, 317,898 PLN at 19%, and 266,877 PLN at 32%. The PIT return is consumed in this variant, not reinvested.

Is it still worth opening IKE or IKZE in 2026? {#18}

Yes, if the account fits your goal and you accept its conditions.

The start of OKI in 2027 does not carry over the unused IKE or IKZE limit from 2026. You do not have to deposit the maximum immediately.

Even a small deposit starts a savings history, although the withdrawal condition counts the calendar year with the deposit, not just the opening of an empty account.

IKE may be reasonable when:

• you invest long-term and want to avoid Polish capital gains tax after meeting the conditions,
• you value the possibility of partial withdrawal before retirement,
• you do not have a large benefit from IKZE deduction or want to first utilize the higher IKE limit,
• you buy global assets that might not benefit from the exemption on OKI.

IKZE may be reasonable when:

• you have a sufficient tax base and will actually use the deduction,
• part of your income is taxed at 32% or you pay a 19% flat tax,
• you can leave funds until age 65,
• you reinvest the tax benefit instead of treating it as extra money to spend.

OKI may be reasonable from 2027 when:

• money may be needed before retirement,
• you mainly use qualified assets and fit within the exemption,
• you more frequently realize gains, interest, or domestic dividends, so deferring tax on a regular account is less significant,
• you accept tax on the average value above the exemption and its possible change after 2027.

If you are just building your strategy, start with your goal, horizon, and risk, and only then choose an account. A helpful guide from CrypS.pl on how to start investing on the GPW and a text on how inflation affects savings and investments will be beneficial.

Do not choose a single winner {#19}

IKE, IKZE, and OKI are not three versions of the same account. IKE rewards patience with a lack of tax on gains after meeting certain conditions.

IKZE converts the current PIT deduction into a 10% tax on the entire future payout.

OKI provides liquidity, but above the exemption, it may charge tax on the average value regardless of the result.

For many people, the sensible answer will not be "either--or," but rather the order:

• IKZE for part of the capital that offers a high deduction and can be kept until the age of 65,
• IKE for long-term investments with greater flexibility for early withdrawal,
• OKI from 2027 for pre-retirement purposes, qualified assets, and surpluses beyond annual retirement limits,
• a regular account where deferring sales, settling losses, or access to instruments unavailable in packages matters.

The biggest mistake is choosing based solely on the slogan "tax-free." You need to compare the entire cycle: the deposit, years of investing, access to money, exit strategy, fees, and the type of asset.
