Child Tax Credit in Poland 2026 — How Much Can You Deduct? Complete Guide with Examples

Poland's child tax credit (ulga na dzieci) is one of the most significant tax benefits for Polish families. For 2026, the amounts and rules remain stable, but it's crucial to understand exactly how much you can claim and how to avoid common filing mistakes.

Child Tax Credit Amounts for 2026

Annual Credit Amounts

The basic annual child tax credit amounts for 2026 are:

• First child: 1,112.04 PLN per year (92.67 PLN per month)
• Second child: 1,112.04 PLN per year (92.67 PLN per month)
• Third child: 2,000.04 PLN per year (166.67 PLN per month)
• Fourth and subsequent children: 2,700.00 PLN per year (225.00 PLN per month)

Examples for Different Family Sizes

Family with one child: 1,112.04 PLN annual credit Family with two children: 2,224.08 PLN annual credit (1,112.04 + 1,112.04) Family with three children: 4,224.12 PLN annual credit (1,112.04 + 1,112.04 + 2,000.04) Family with four children: 6,924.12 PLN annual credit (1,112.04 + 1,112.04 + 2,000.04 + 2,700.00)

Income Threshold — When You Lose the Credit

Income Limits

The child tax credit is available to families with annual income:

• Single parents: up to 112,000 PLN per year
• Married couples: up to 112,000 PLN combined

What Happens When You Exceed the Threshold

If you exceed the income threshold, the credit is gradually reduced using this formula:

• Reduction = (income - 112,000) × number of children × 6.67

Example: Married couple with two children and income of 120,000 PLN

• Excess: 120,000 - 112,000 = 8,000 PLN
• Reduction: 8,000 × 2 × 6.67 = 106.72 PLN
• Final credit: 2,224.08 - 106.72 = 2,117.36 PLN

How to File Your PIT Return — Step by Step

PIT-37 Form

1. Section G: Enter the number of children eligible for the credit
2. Line 134: Enter the total annual credit amount
3. Line 135: If you exceeded the income threshold, enter the reduction amount

PIT-36 Form

1. Line 25: Number of children eligible for the credit
2. Line 134: Credit amount calculated according to the table
3. Line 135: Any reduction due to exceeding the threshold

Required Documents

• Children's birth certificates
• Disability certificates (if applicable)
• Documents proving custody of the child
• Income certificates from spouse

Common Mistakes When Claiming the Credit

Mistake 1: Incorrect Age Calculation

Problem: Many parents don't realize that children are eligible until age 18, or until age 25 if they're students.

Solution: A child must reach age 18 during the tax year to lose eligibility (unless they're studying).

Mistake 2: Double Claiming by Both Parents

Problem: Both parents try to claim the same child.

Solution: Decide before filing which parent will claim which child. You can split children between parents.

Mistake 3: Incorrect Calculation When Exceeding Threshold

Problem: The formula for reduction when exceeding 112,000 PLN income is complex.

Solution: Use a tax calculator or professional tax software for accurate calculations.

Mistake 4: Forgetting the Credit When Changing Tax Forms

Problem: When switching from flat tax to progressive tax, people forget about available credits.

Solution: Check all available credits regardless of your taxation form.

Child Tax Credit vs Other Family Benefits

Relationship with 800+ Program

The child tax credit in PIT is independent of the 800+ benefit. You can use both forms of support simultaneously.

Relationship with Disability Tax Relief

If your child has disabilities, you can use:

• Child tax credit (standard amounts)
• Disability tax relief (additional preferences)

Tax Optimization Strategies

For Couples Approaching the Threshold

Situation: A married couple's combined income is 110,000 PLN in 2025 but may increase in 2026.

Strategy:

• Consider filing separately
• Shift some income to the spouse with lower earnings
• Look into tax credits that reduce taxable income

For Parents in Informal Relationships

Situation: An unmarried couple raising children together.

Strategy:

• Each parent has their own 112,000 PLN threshold
• You can split children between partners for optimization
• One parent can claim more children if the other has higher income

Financial Planning with Child Tax Credits

The child tax credit represents real savings that should be factored into your household budget. For a family with three children, that's over 4,200 PLN annually — an amount that can significantly improve your family's financial comfort.

How to Use the Savings:

• Increase contributions to children's savings accounts
• Invest in children's education (courses, books, equipment)
• Create a family vacation fund

Tracking Your Financial Situation

To better plan family finances and optimize taxes, it's worthwhile to regularly monitor your income and expenses throughout the year. Tools like Freenance can help track cash flows and optimize tax settlements year-round, ensuring you make the most of available credits and deductions.

Future Outlook

The government has repeatedly signaled intentions to increase child tax credit amounts, particularly for families with multiple children. It's worth following changes in tax law that may affect credit amounts in coming years.

Potential Changes

• Increased credit amounts for third and subsequent children
• Raised income thresholds
• Simplified calculation rules

International Comparison

Poland's child tax credit system is competitive within the European Union:

• Germany: Child allowance (Kinderfreibetrag) of €8,952 per child annually
• France: Tax quotient system based on family size
• Czech Republic: Tax credit of 24,840 CZK per child annually

Poland's system provides substantial support, particularly for families with three or more children.
