New Reporting Rules for Sole Proprietors in 2026

For sole proprietors, the start of the year is not only about business planning but also a period of active reporting. In 2026, the rules for submitting reports are changing significantly compared to previous years.

If 2025 was a year where businesses adapted to new military tax rates and experimental reporting formats, 2026 marks a return to a more familiar rhythm. The shift back to quarterly logic, new declaration forms, and the integration of additional payments into standard forms require maximum attention from the sole proprietor.

In this article, we will break down everything an entrepreneur needs to know to avoid penalties from the State Tax Service.

How 2026 Reporting Differs from 2025

2025 was a transitional period. Many entrepreneurs remember it for the introduction of monthly combined reporting for Personal Income Tax (PIT), military tax, and Unified Social Contribution (USC). This led to confusion — many sole proprietors became accustomed to monthly reports and mistakenly followed this logic into 2026.

In 2026, the government returned to a more straightforward reporting structure:

Many sole proprietors, reporting for 2025, used forms that were relevant a year ago out of habit. However, the DTS electronic system in 2026 automatically rejects old form formats.

What Has Changed in Sole Proprietor Reporting in 2026: Key Innovations

The logic for submitting combined tax reporting changed in 2026. Let’s look at the main features in more detail.

🔸 Return to the Quarterly Cycle

In 2026, entrepreneurs must submit reports once per quarter. This applies to sole proprietors working solo and those who have hired employees. However, it’s crucial to remember that although the report is filed once every three months, the data within it (e.g., accrued USC or PIT amounts for employees) must be detailed separately for each month.

🔸 Military Tax in the Unified Tax Declaration

The military tax for a sole proprietor is no longer a separate payment receipt without a report, but a full section in the annual (for Groups 1–2) or quarterly (for Group 3) declaration. The Ministry of Finance updated the forms so that entrepreneurs can independently declare their tax obligations in a single document.

🔸 Digitalization and Automatic Checks

In 2026, the tax service is even more actively using automatic reconciliation algorithms. This means that any discrepancy between the data in your declaration and the data from bank statements or RRO/PRRO (cash registers) is automatically flagged by the system.

Which Reports Must Sole Proprietors File in 2026?

The list of reports depends on the chosen group and the presence of hired staff. Specifically, in 2026, sole proprietors of Groups 1–3 must submit:

• The sole proprietor tax declaration (depending on the tax group);
• Combined reporting for PIT, military tax, and USC — if they have hired employees;
• USC reporting — as part of the combined calculation.

All sole proprietors with hired employees file the combined reporting for PIT, military tax, and USC quarterly. This is a critically important document where all payments to individuals are recorded. Sole proprietors without hired employees file only the declaration for themselves.

New Declaration Forms: What to Pay Attention to

The Ministry of Finance of Ukraine updated the tax reporting forms in 2025–2026. This was necessary to reflect the military tax and clarify USC amounts.

Why can’t you use old forms?

1. Lack of mandatory fields — for instance, old forms lack sections for accruing the 1% (or another current rate) military tax for a sole proprietor in Group 3.
2. Technical rejection — the electronic office or reporting services will issue an error message: «The form is no longer valid».
3. Risk of penalty — еhe tax authority equates reporting using the incorrect form to non-submission.

When to File Sole Proprietor Reports in 2026

The standard rule applies in 2026: reports are filed within 40 or 60 days after the end of the reporting period.

Who May Not File Reports in 2026?

Exemption from reporting in 2026 is an exception, not the rule. The following categories of sole proprietors do not file reports:

• Sole proprietors on the general system without entrepreneurial activity. If there was no movement of funds or taxable objects throughout the year, the sole proprietor may not file the property status declaration. However, for sole proprietors on the simplified tax system, the Unified Tax payment declaration remains mandatory — they must indicate zero income amounts in it.
• Sole proprietors-pensioners and persons with disabilities. They are exempt from filing Appendix 1 for USC «for themselves», but are obligated to file the Unified Tax declaration.
• Sole proprietors who have suspended operations. It is important to understand that the lack of income does not cancel the sole proprietor status. As long as you are in the register, you report (even with zero amounts).

Typical Sole Proprietor Errors When Submitting Reports

Even experienced entrepreneurs sometimes make mistakes in tax reports. The most common errors in sole proprietor reports include:

• Incorrect reporting frequency. Some sole proprietors continue to file the monthly reports that were relevant in 2025, instead of the quarterly ones in 2026.
• Incorrect form identifier. Using forms from the previous year that are no longer valid.
• Missing Appendix 1 (USC). The sole proprietor files the main annual declaration but fails to attach Appendix 1 regarding the payment of the Unified Social Contribution.
• Errors in the KVED codes. If you received income for a KVED code not listed in your register, the tax authority may revoke your status as a Unified Tax payer.

Penalties for Reporting Violations

In 2026, tax legislation provides for the following penalties for reporting violations:
