On August 5, 2025, the Ministry of Finance in Poland unveiled a groundbreaking solution for savers and investors – OKI (Osobiste Konto Inwestycyjne). This innovative investment tool is being called the largest tax relief in Polish history for individuals who want to grow their wealth while minimizing tax burdens. 

What is OKI?

OKI is a voluntary savings and investment account introduced by the Polish government in 2025. Its primary goal is to encourage citizens to actively invest their savings in capital markets and diversify away from traditional bank deposits and cash holdings. 

Key objectives of OKI include: 

• supporting household wealth growth through preferential tax treatment, 
• boosting investments in the Polish capital market,
• enhancing economic competitiveness by channeling private funds into innovative businesses. 

Furthermore, OKI gives Polish citizens the opportunity to invest up to 100,000 PLN tax-free, with additional favorable taxation for amounts above this threshold. 

Who can use OKI?

Beginner investors – people who want to start investing with low risk and clear rules. 

Conservative savers – those who previously kept money in cash or bank deposits but are now looking for better returns without high taxes. 

Experienced investors – individuals with larger portfolios who want to optimize their tax efficiency. 

More importantly, OKI can also be relevant for entrepreneurs who invest in financial markets alongside running a business. Working with a professional accounting office ensures that your investments are aligned with tax regulations and that you take full advantage of available deductions. 

Key rules and investment limits of OKI

Tax-free investments up to 100,000 PLN 

The biggest advantage of OKI is the ability to invest up to 100,000 PLN completely tax-free. This means that any profits generated from stocks, bonds, or investment funds within this limit are exempt from taxation. 

This directly addresses the long-standing issue of the 19% Belka tax (capital gains tax) that has historically reduced investors’ net returns. 

Savings component up to 25,000 PLN

OKI also includes a savings element, allowing individuals to deposit up to 25,000 PLN into safe instruments like bank deposits or government savings bonds – again with full tax exemption. 

This makes OKI attractive not only for active investors but also for people who prefer low-risk, stable returns. 

Preferential tax on amounts above 100,000 PLN 

If your portfolio exceeds 100,000 PLN, the surplus is not fully exempt. Instead, it is subject to a low asset tax of 0.8–0.9%, depending on the structure of your investments. 

This is still significantly lower than the 19% capital gains tax, making OKI one of the most competitive investment options in Europe. 

What financial investments can you invest in with OKI?

Capital Market Instruments

Through OKI, investors can access a wide range of market instruments, including: 

• shares of publicly listed companies, 
• investment funds (equity, mixed, and bond funds),
• government and corporate bonds. 

This diversity allows investors to tailor their portfolio to their risk tolerance and financial goals. 

Deposits and saving bonds

For those less comfortable with stock market risks, OKI also allows traditional saving products such as: 

• fixed-term deposits, 
• treasury savings bonds. 

This makes OKI a hybrid tool, combining opportunities for growth with security for conservative investors. 

Why was OKI introduced?

Low investment rates in Poland

For years, Poland has faced one of the lowest investment-to-GDP ratios in the European Union. This has limited the pace of innovation and competitiveness of the economy. 

Excessive reliance on cash and deposits

More than 50% of Polish household savings are held in cash or bank deposits – the highest share in the EU. While this feels safe, it generates minimal returns, often below inflation.

Inspiration from Sweden’s ISK model 

OKI system was inspired by Sweden’s Investeringssparkonto (ISK), introduced in 2012. Today, more than 40% of Swedish adults use ISK to grow their wealth tax-efficiently. The Polish government hopes to replicate this success by encouraging more people to participate in financial markets. 

Economic impact

The introduction of OKI is expected to have far-reaching effects on both households and the wider economy: 

• increased participation in capital markets – more citizens investing in stocks and bonds. 
• greater access to financing for businesses – especially start-ups and innovative SMEs. 
• higher innovation levels – as more capital flows into technology–driven enterprises. 
• faster economic growth – supporting Poland’s trajectory toward becoming one of the top 20 global economies by 2025, with GDP reaching 85% of the EU average. 

By eliminating the burden of the Belka tax on most individual investors, OKI could become the catalyst that shifts Poland from a savings–focused economy to an investment–driven one. 

When will OKI be launched?

Although the solution was officially announced in August 2025, the Minister of Finance emphasized that the IT work required to implement the Osobiste Konto Inwestycyjne will take at least six months.

In practice, this means that the real launch of OKI will take place no earlier than mid-2026.
