Lump Sum vs Tax Scale - Which to Choose?

Choosing your tax form is one of the most consequential financial decisions an entrepreneur makes. The right choice can save you several or even tens of thousands of zloty per year. In this article, we compare two popular options: the lump-sum tax on registered revenue (ryczałt) and the tax scale (zasady ogólne), while also referencing the flat tax as a benchmark.

Three Tax Forms - Overview

Tax Scale (General Rules)

  • Rates: 12% on income up to PLN 120,000, 32% above
  • Tax base: income (revenue minus deductible expenses)
  • Tax-free allowance: PLN 30,000
  • Tax credits: full catalog (child credit, joint filing with spouse, and others)
  • Health contribution: 9% of income, not deductible

Flat Tax

  • Rate: 19% regardless of income level
  • Tax base: income
  • Tax-free allowance: none
  • Tax credits: limited catalog
  • Health contribution: 4.9% of income, partially deductible (up to a limit)

Lump-Sum Tax on Registered Revenue (Ryczałt)

  • Rates: from 2% to 17% depending on the type of activity
  • Tax base: revenue (without deducting expenses)
  • Tax-free allowance: none
  • Tax credits: limited catalog
  • Health contribution: flat rate depending on revenue bracket, 50% deductible

Lump-Sum Rates - Who Pays What

The lump-sum rate depends on the type of business activity:

| Rate | Type of Activity | |------|-----------------| | 17% | Liberal professions (without special conditions) | | 15% | Brokerage, consulting, advertising | | 14% | Healthcare services | | 12% | IT services, programming, software publishing | | 10% | Real estate transactions | | 8.5% | Services (most types), rental up to PLN 100,000 | | 5.5% | Manufacturing, construction | | 3% | Trade, gastronomy | | 2% | Sale of plant and animal products |

The most commonly chosen rates are 12% (IT and specialized services), 8.5% (general services), and 3% (trade).

When the Lump Sum Is More Advantageous

The lump sum is most beneficial when:

1. You Have Low Business Expenses

This is the decisive factor. The lump sum does not allow expense deductions, so if your business costs are low (e.g., you work as a freelancer and only need a laptop and Internet), the lump sum often wins. When expenses represent less than 30-40% of revenue, the lump sum is typically more favorable.

2. Your Lump-Sum Rate Is Low

A programmer paying 12% on revenue, with costs around 10-15%, will pay less than under the tax scale or flat tax. A trader with a 3% rate almost always benefits from the lump sum.

3. You Do Not Need Tax Credits

The lump sum does not provide access to the child tax credit or joint filing with a spouse. If these credits are not relevant to you, the lump sum becomes more attractive.

4. You Want Simpler Bookkeeping

Under the lump sum, you only maintain a revenue register - you do not need to document and record expenses (though it is wise to do so in case you change your tax form later).

When the Tax Scale Is Better

1. You Have High Business Expenses

If expenses represent more than 50-60% of revenue (e.g., you purchase materials, goods for resale, or hire subcontractors), the tax scale lets you significantly reduce your tax base.

2. You Want to Use Tax Credits

The child tax credit can save over PLN 1,100 per child per year. Joint filing with a spouse is advantageous when one partner earns significantly more. These credits are available only under the tax scale.

3. Your Income Is Low

The PLN 30,000 tax-free allowance under the tax scale means you pay no tax on the first PLN 30,000 of income. The lump sum has no such mechanism - you pay from the first zloty of revenue.

4. You Have Multiple Income Sources

Under the tax scale, you can combine income from different sources, which can be tax-advantageous (e.g., a business loss offsets income from other sources).

Comparison with Examples

Example 1: Freelance Programmer

  • Annual revenue: PLN 200,000
  • Expenses: PLN 20,000 (laptop, Internet, office)
  • Income: PLN 180,000

Lump sum 12%: PLN 200,000 x 12% = PLN 24,000 in tax Tax scale: (PLN 120,000 x 12%) + (PLN 60,000 x 32%) - PLN 3,600 (tax-reducing amount) = PLN 29,400 in tax Flat tax: PLN 180,000 x 19% = PLN 34,200 in tax

The lump sum wins by over PLN 5,000 per year.

Example 2: Trading Company

  • Annual revenue: PLN 500,000
  • Expenses (goods, transport, warehouse): PLN 380,000
  • Income: PLN 120,000

Lump sum 3%: PLN 500,000 x 3% = PLN 15,000 in tax Tax scale: PLN 120,000 x 12% - PLN 3,600 = PLN 10,800 in tax

The tax scale wins because expenses represent 76% of revenue.

Example 3: Business Consultant

  • Annual revenue: PLN 300,000
  • Expenses: PLN 30,000
  • Income: PLN 270,000

Lump sum 15%: PLN 300,000 x 15% = PLN 45,000 in tax Tax scale: (PLN 120,000 x 12%) + (PLN 150,000 x 32%) - PLN 3,600 = PLN 58,800 in tax Flat tax: PLN 270,000 x 19% = PLN 51,300 in tax

The lump sum wins, despite the relatively high 15% rate.

Health Insurance Contribution - A Critical Factor

Since 2022, the health insurance contribution depends on your tax form and significantly affects total costs:

  • Tax scale: 9% of income, minimum approx. PLN 380/month, not deductible
  • Flat tax: 4.9% of income, minimum approx. PLN 380/month, partially deductible
  • Lump sum: flat rate depending on revenue bracket (approx. PLN 380-940/month), 50% deductible

At higher income levels, the health contribution under the tax scale becomes very significant (no upper cap), which further favors the lump sum or flat tax.

When and How to Change Your Tax Form

You can notify a change in tax form:

  • By February 20 of the tax year the change applies to
  • By updating your CEIDG entry (form CEIDG-1)
  • The change takes effect from January 1 of that year

You cannot change your tax form mid-year. Therefore, it is worth running calculations at the end of each year and making your decision before the February deadline.

Who Cannot Choose the Lump Sum

The lump sum is not available to everyone. You cannot choose it if you:

  • Operate a pharmacy or pawnshop
  • Manufacture excise goods
  • Provide services to a former employer (the same services you performed as an employee, in the year of transition)
  • Your revenue in the previous year exceeded EUR 2 million (for businesses operated as civil or general partnerships)

Summary - How to Decide

There is no single universal answer. The optimal choice depends on:

  1. Revenue and expense levels - the lower your expenses, the more advantageous the lump sum
  2. Lump-sum rate for your industry - a 3% rate is almost always a good choice; 15-17% requires careful calculation
  3. Need for tax credits - children, spouse, other credits favor the tax scale
  4. Income level - at high income levels, the tax scale (32%) is the most expensive
