Employment and sole proprietorship: organising PIT-11 contributions and your own payments

This guide covers reconciling documentation of Polish social insurance contributions when you are both employed and running a sole proprietorship. It does not determine insurance obligations or how to allocate deductions between tax returns.

1. Separate the two sources of documentation

The podatki.gov.pl guide identifies contributions governed by the Act of 13 October 1998 on the social insurance system:

• PIT-11 from the payer: pension, disability pension and sickness insurance contributions withheld and reported by the payer.
• The entrepreneur’s own payments: contributions for your own pension, disability pension, sickness and accident insurance paid during the tax year. One condition for deducting them is that they have not previously been included in tax-deductible costs.

For your own payments, prepare evidence that you incurred the expense. The source lists payment receipts, transfer confirmations, bank statements and certificates from ZUS, as well as information from the payer, such as PIT-11.

As an organisational measure, it is worth keeping separate lists of PIT-11 amounts and your own payments. Having both a PIT-11 and a transfer confirmation does not, by itself, prove that the same contribution has been reported twice. Compare the documented amounts and how they have already been treated for tax purposes.

2. Check which amounts have already been claimed

You cannot deduct contributions that:

• you have included in tax-deductible costs;
• you have already deducted in another tax return.

The prohibition concerns deducting the same contributions again, not simply using two sources of documentation. When reconciling documents, it is therefore worth marking amounts already included in costs or deducted in another return.

3. Account for the other exclusions

Under the deduction rules, you also cannot deduct contributions:

• refunded to you in any form;
• whose assessment basis is income or revenue exempt from tax under statutory provisions;
• whose assessment basis is income for which tax collection has been waived under the provisions of the Tax Ordinance.

4. Distinguish costs from deductions

How contributions are treated depends on the form of taxation and whether the conditions are met. These are not three freely interchangeable ways of claiming every contribution:

• Tax-deductible costs: the source provides this option for business activity taxed under the tax scale or the 19% flat income tax. Contributions included in costs cannot subsequently be deducted.
• Deduction from income: applies to taxation under the tax scale or the 19% flat income tax, subject to the conditions and exclusions described above.
• Deduction from revenue: applies to lump-sum tax on recorded revenue, also subject to the conditions and exclusions.

The deduction covers expenditure actually incurred. For deductions from income, account for the source’s stated restriction to the amount of income earned. This wording should not be applied to lump-sum taxation as an income-limit rule: the source separately describes a deduction from revenue in that case. Evidence of payment therefore does not guarantee that the entire documented amount can be deducted.

5. Prepare an optional summary for the annual tax return

To keep things organised, you can prepare a list containing:

• the source document: PIT-11 or evidence of your own payment;
• the contribution type and documented amount;
• the amount already included in costs;
• the amount already deducted in another return;
• an indication of any refund or other exclusion from deduction.

This is an organisational recommendation, not an additional record-keeping obligation arising from the cited guide. Contributions are ultimately settled in the annual tax return.

This text does not cover health insurance contributions, employer-funded contributions, foreign contributions or contributions for cooperating persons. The year in which overdue contributions are deductible, corrections, deadlines, calculations and carrying forward unused deductions are also outside its scope.
