The progressive tax scale, also known as the “general principles” (zasady ogólne), is the default and most traditional form of taxation in Poland. While it’s most commonly associated with employment contracts, it’s also available for sole proprietors. It is a flexible system that, thanks to its tax brackets, tax-free allowance, and numerous reliefs, can be the perfect choice, especially when you’re starting your business journey.

How Does the Progressive Tax Scale Work? Key Principles

When you choose the progressive scale, you pay tax based on your income, which is your revenue minus business-related costs. This fundamental rule allows you to lower your tax base with all your company expenses.

The key features of Poland’s tax brackets are:

• Two Tax Brackets:
  • 12% – for annual income up to 120,000 PLN (approx. €27,600).
  • 32% – paid only on the surplus income above 120,000 PLN.
• Tax-Free Allowance: Income up to 30,000 PLN (approx. €6,900) per year is completely exempt from PIT (Personal Income Tax).
• Full Cost Deduction: You can reduce your revenue by deducting business costs (e.g., leasing, fuel, equipment, software) by maintaining a Revenue and Expense Ledger (KPiR).
• Access to All Tax Reliefs: This is the biggest advantage of this tax form.

The Health Insurance Contribution: What You Must Know

This is a critical piece of information: On the progressive tax scale, your monthly health insurance contribution is 9% of your business income. Crucially, this contribution cannot be deducted from your income or your tax. It acts as an additional charge that you must factor into your financial calculations.

How to Calculate Your Tax: A Simple Example

Let’s imagine your annual income (revenue minus costs) was 150,000 PLN.

• First Bracket (up to 120,000 PLN):
  • From the 120,000 PLN income, we subtract the tax-free allowance: 120,000 - 30,000 = 90,000 PLN.
  • The tax on this portion is: 90,000 PLN * 12% = 10,800 PLN.
• Second Bracket (surplus over 120,000 PLN):
  • Your surplus income is: 150,000 PLN - 120,000 PLN = 30,000 PLN.
  • The tax on this portion is: 30,000 PLN * 32% = 9,600 PLN.
• Total Tax Due:
  • 10,800 PLN + 9,600 PLN = 20,400 PLN.

From this amount, you can still deduct any available tax reliefs!

Main Advantages: Tax Reliefs and Joint Filing

What truly sets the progressive scale apart is its access to a full range of tax preferences. Among others, you can benefit from:

• Joint Tax Filing with a Spouse: This is an ideal solution if your spouse has no income or a significantly lower income. It allows you to effectively split the income between two people, which can prevent you from entering the higher 32% tax bracket.
• Child Tax Relief: A key benefit for parents.
• Other Reliefs: Including deductions for internet expenses, rehabilitation, thermal modernization projects, donations, IKZE (private pension contributions), and more.

Who Is the Progressive Tax Scale Best For?

The general principles will be advantageous for you if:

• You have low to moderate income that doesn’t significantly exceed the 120,000 PLN threshold.
• You want to use tax reliefs, especially the child tax credit or joint filing with a spouse.
• You run a business with fluctuating or seasonal income, where flexibility is key.
• You are at the beginning of your business journey and your earnings are not yet high.

Examples of businesses where this scale works well include tutors, artists, craftspeople, freelancers who are just starting out, and entrepreneurs whose spouses do not work.

When Is the Progressive Tax Scale Not a Good Choice?

You should consider a different tax form (like the Flat Tax or Lump-Sum Tax) when:

• You earn significantly more than 120,000 PLN per year, because every zloty of surplus income is taxed at a high 32% rate.
• You don’t use any tax reliefs, have no children, and file your taxes alone—in this case, you lose the biggest advantages of this system.
• You have consistently high income with very low costs—in this scenario, the lump-sum tax may be a much cheaper option.

Progressive Scale vs. Flat Tax vs. Lump-Sum: Key Differences

As you can see, the choice depends on your individual circumstances. The progressive tax scale for 2025 is a safe and flexible option that offers the most privileges but can become expensive for high earners who are not eligible for tax reliefs.
