When opening a Jednoosobowa Działalność Gospodarcza (JDG), you must choose a taxation system. Your choice affects how much tax you pay, whether you can deduct business expenses and how your health insurance contribution is calculated.
The 3 main taxation systems are:
- Tax scale (Skala podatkowa)
- Flat tax (Podatek liniowy)
- Lump-sum tax (Ryczałt)
📊 Tax System Comparison
| Tax System | Tax Rate | Taxed On | Business Expenses | Best For |
|---|---|---|---|---|
| Tax scale | 12% / 32% | Profit | ✅ | Small and medium businesses |
| Flat tax | 19% | Profit | ✅ | High-income entrepreneurs |
| Lump-sum tax | 2%–17%* | Revenue | ❌ | Freelancers and businesses with low expenses |
*The exact lump-sum rate depends on the type of business activity (PKD).
📈 Tax Scale (Skala podatkowa)
With the tax scale, you pay tax on your profit, which is your revenue minus business expenses.
Advantages
- Tax-free allowance
- Business expenses can be deducted
- Access to most tax reliefs
- Suitable for businesses with significant expenses
Disadvantages
- Tax increases to 32% after exceeding the annual income threshold
- Health insurance contribution is calculated separately
📉 Flat Tax (Podatek liniowy)
The flat tax applies a fixed 19% rate regardless of your income.
You pay tax on your profit, not your revenue.
Advantages
- Fixed tax rate
- Business expenses can be deducted
Disadvantages
- No tax-free allowance
- Limited access to some tax reliefs
💼 Lump-sum Tax (Ryczałt)
With the lump-sum system, tax is calculated from your revenue, not your profit.
This means you generally cannot deduct business expenses.
The tax rate depends on your business activity and ranges from 2% to 17%.
Common rates include:
| Business Activity | Tax Rate |
|---|---|
| IT programming | 12% |
| IT consulting | 8.5% |
| Marketing services | 15% |
| Construction services | 5.5% |
| Retail trade | 3% |
| Rental income | 8.5% or 12.5% (depending on revenue) |
The applicable rate always depends on the PKD code and the actual services provided.
🧾 Revenue vs Profit
Understanding the difference is important:
- Revenue is all the money your business receives
- Profit is the money left after deducting business expenses
Example:
- Revenue: 20,000 PLN
- Business expenses: 6,000 PLN
- Profit: 14,000 PLN
With Tax Scale or Flat Tax, you pay tax on 14,000 PLN.
With Lump-sum Tax, you pay tax on 20,000 PLN.
🔄 Can You Change Your Tax System?

- Through CEIDG
- At the Tax Office (Urząd Skarbowy)
