In 2026, all sole proprietors are required to keep income records, but the format of the book depends on the taxation system: for simplified system taxpayers without VAT it may be in a free form (Excel), while for VAT payers and those on the general taxation system – in the format approved by the Ministry of Finance.

Is it mandatory to keep this book? What is the penalty for its absence? Can it be kept in Excel instead of the official form? How does the book help to pass financial monitoring in banks?

In this article, we will review all the nuances of keeping the income record book for sole proprietors in 2026: from legislative requirements to practical advice on how to automate this process and not waste time on it. 

What Is the Income Record Book for a Sole Proprietor and Why It Is Needed

The income record book does not replace primary documents (contracts, acts, receipts) but is formed on their basis and used as a summarized accounting register. It is a document in which an individual entrepreneur records all sources of income received in the course of business activity.

Why Is the Income Record Book Needed?

1. Legal Requirement
The Tax Code of Ukraine obliges sole proprietors to keep income records. This is not a recommendation but an obligation.

2. Centralization of Income Information
The book helps an entrepreneur consolidate all sources of income into one centralized system:

• cash receipts through RRO/PRRO
• non-cash payments to the sole proprietor’s account
• other forms of income

3. Cash Flow Control
Thanks to the book, you clearly understand your cash flow and can track the income limit – which is especially important for sole proprietors on the simplified taxation system.

4. Basis for Tax Reporting
Data from the income record book is used to complete the annual tax declaration.

5. Confirmation of the Source of Funds
The book is one of the components of the security of your money in the bank – it helps to pass financial monitoring and explain the origin of funds.

The income record book serves as a transitional bridge between the actual receipt of funds and the official reporting to the state. Legislation requires that every figure in your declaration be supported by a corresponding entry in primary documents. If you maintain the Book systematically, the reporting process turns into a simple transfer of final amounts, which minimizes the risk of errors and unnecessary questions from the tax authorities.

This is the logic established by legislation around the income record book.

Who Is Required to Keep the Sole Proprietor Income Record Book in 2026

The requirement to keep income records is set out in Articles 44.1 and 177.10 of the Tax Code of Ukraine. However, the rules differ significantly depending on your taxation system and whether you have VAT payer status.

For convenience, we have summarized all requirements in a comparative table:

More details about each type of accounting:

• For general system taxpayers: The most detailed type of accounting. You must record not only income but also documented expenses, since your tax is calculated from the difference between them.
• For VAT payers: The book must contain data for inclusion in the VAT tax declaration. It is necessary to clearly separate amounts with VAT and without VAT, as well as record the details of tax invoices.
• For simplified taxpayers without VAT: You – are the real “lucky ones”. The tax authority allows you to keep records in any convenient format. The main requirement – monthly reflection of income. This may be a regular Excel file, a Google spreadsheet, or an automated system.

Is It Necessary to Register the Income Record Book and What Penalties Are предусмотрed

In 2026, the Income Record Book is surrounded by the greatest number of myths. Let’s clarify the two main questions: do you need to go anywhere and what are the consequences of not keeping records.

Today, the Income Record Book is exclusively an internal document of the entrepreneur. 

Previously, a paper book had to be numbered, stitched, and personally taken to the tax office for sealing and the inspector’s signature. Now you simply start keeping records in a convenient format (paper, Excel, or software). No visits to the State Tax Service, no seals or stamps on the book are required.

What is the cost of not keeping records?

Formally, the penalty is applied not for the “book” itself, but for violating the requirements for maintaining tax records and storing primary documents in accordance with the Tax Code of Ukraine.

Absence of the book as a primary document – UAH 1,020. Repeated violation within a year – UAH 2,040

Important nuance: Although the fine of UAH 1,020 may seem insignificant compared to business turnover, the absence of the book entails much more serious “indirect” risks:

1. Bank account blocking: During financial monitoring, the bank requires the book as proof of the legality of income. No book – the bank terminates business relations.
2. Problems during inspection: If the tax authority does not see the book, it may question the correctness of your declaration, which may lead to additional tax assessments and penalties.

Even if you keep the book in Excel, upon request from the tax authority you must provide it in printed and signed form (in case of a paper audit) or as a generated electronic document with a qualified electronic signature.

Who Can Check the Income Record Book?

The main authorities entitled to monitor the maintenance of the Income Record Book are the State Tax Service and banking institutions. The tax inspection may request the Book during scheduled, unscheduled, or desk audits to reconcile declared amounts with actual receipts.

At the same time, in 2026, checks by banks within the framework of financial monitoring are critically important. If a bank detects unusual or large transfers to the account of a sole proprietor, the Book becomes the main document that, together with contracts and invoices, confirms the legality of the origin of funds. In addition, in exceptional cases related to investigations of economic offenses, other law enforcement or supervisory authorities may also gain access to the Book.

The Role of the Income Record Book in Bank Financial Monitoring

The income record book – is one of the key tools for passing financial monitoring in banks. When can a bank request the income record book?

1. Large or Unusual Receipts
If a large amount (for example, UAH 500,000) is suddenly credited to a sole proprietor’s account, while the previous turnover was UAH 50,000 per month – the bank may request an explanation.

2. Suspicious Activity
Many transfers from individuals, unusual counterparties, transactions with high-risk countries.

3. Lack of Logical Consistency in Transactions
For example, you are registered as a sole proprietor with the KVED “Consulting services”, but you receive payments with the purpose “Payment for construction materials”.

The income record book – is a document that confirms:

• Where the money came from
• That it is lawful business activity
• That the amounts correspond to real transactions

The bank does not conduct a tax audit and does not assess the correctness of tax calculations, but uses the income record book as proof of the logical and lawful movement of funds.

Therefore, it is a component of the security of your money in the bank. It helps you successfully pass financial monitoring and explain the origin of funds.
