Your year end, step by step

Self-employed, company or non-profit (ASBL): what to do after the financial year closes, in order, with your dates and the official links. A natural person does not file annual accounts. A company files them with the National Bank; a non-profit keeping simplified accounts files them free of charge at the registry of the enterprise court.

A company is small if it exceeds no more than one of these criteria: 50 employees, €11,250,000 turnover, €6,000,000 balance sheet total; micro with 10 employees, €900,000 and €450,000, if it is neither a subsidiary nor a parent company. A non-profit keeps simplified accounts if it exceeds no more than one of these criteria: 5 employees, €391,000 income, €1,562,000 assets, €1,562,000 debts. A size only changes if the criteria are exceeded two financial years in a row.

Filing with the National Bank, step by step

  1. Log in to Filing, the Central Balance Sheet Office’s filing application, with your electronic identity card (reader and PIN) or itsme.
  2. Choose how to file: import the XBRL file prepared by your accountant, send a single PDF, or enter the accounts online, screen by screen, if you have no accounting software.
  3. Validate and send. A PDF is checked by the National Bank first.
  4. Pay by card or by transfer with the structured reference: the amount must arrive within 6 working days of the ‘ready for payment’ status, or the filing is refused.
  5. Keep the proof. The official filing date is the date it was sent. The accounts become public in the National Bank’s ‘Consult’ application.

If late, a company pays a surcharge from the first day of the 9th month after closing: €151, €227 then €453 for a small company, €504, €755 then €1,510 for the others (2026 amounts). A non-profit pays no surcharge, but its court actions can be suspended.

Filing at the registry, for a non-profit with simplified accounting

  1. Have the accounts approved: the year’s accounts and the next year’s budget, by the general meeting, no later than 6 months after closing.
  2. Print the approved accounts on white A4 paper, on one side, in black, with a blank strip of 2 cm at the top of each page and, at the top, the non-profit’s name, its legal form, the full address of its registered office and its enterprise number; have them signed by hand by the people who represent it, with their name and capacity.
  3. Hand them in at the registry of the enterprise court for the non-profit’s registered office, within 30 days of the meeting, with your identity card. Filing is free; bring two copies (the Belgian Official Gazette asks for one, the circular of the Minister of Justice for two). Sending by post is only provided for documents that are published: ask your registry whether it accepts it.
  4. Confirm the UBO register in MyMinfin, at least once a year.

To prepare everything, from bank statement to accounts printed in the legal format: my non-profit’s annual accounts.

What you can do yourself, and when to call an accountant

No rule requires you to use an accountant, except the statutory auditor (a registered auditor) for a company or non-profit that is not small.

  • On your own: keep a self-employed person’s three journals and take the inventory, file the VAT returns and the client listing on Intervat; for a non-profit with simplified accounting, keep the single book, draw up the statement of income and expenditure and the budget, and file at the registry.
  • On your own, with some effort: enter the micro format for a micro company or micro non-profit in Filing, if its double-entry accounts are already correct.
  • Better with an accountant: the tax return with depreciation and expenses, any double-entry accounting, the corporate tax or legal entities tax return, the abridged or full format, the social balance sheet, a change of size.

How long should you keep the books and documents?

Accounting law requires 7 years from 1 January after closing; tax law, 10 years since 2023. In practice, keep everything for 10 years.

Frequently asked questions

Does a self-employed person have to file annual accounts?

No. A natural person does not publish accounts. They keep their books (three journals and an inventory up to €500,000 turnover excluding VAT), file their VAT returns and their tax return.

Can I file the accounts with the National Bank myself?

Yes, with your electronic identity card or itsme, in the Filing application. For a micro company, you can enter the micro format online; for the others, the accountant usually prepares the XBRL file.

Does a non-profit that files late pay a fine?

No financial surcharge for a non-profit. But as long as its accounts are not filed, its court actions can be suspended, and a judicial dissolution can be requested.

Where is the registry of the enterprise court?

The one for the judicial district of the non-profit’s registered office, at the legal entities department. Filing there is free; the list of registries, with their addresses and opening hours, is on the page My non-profit’s annual accounts.

Why are some dates ‘to be confirmed’?

The dates of the 2027 tax returns had not yet been published by the FPS Finance on 23 October 2026. Indexo does not make them up: they will be added as soon as they are published.
