The calendar
Three dates carry the whole obligation, counted from the end of your financial year:
- Prepare within five months. The board draws up the annual accounts. Shareholders can grant an extension of up to five further months — in an owner-managed BV that is a one-line resolution.
- Adopt, then file within eight days. The shareholders' meeting adopts the accounts; filing with the KVK follows within eight days of adoption.
- The hard stop: twelve months. Whatever happens with preparation and adoption, the accounts must be filed at the latest twelve months after the end of the financial year. For a calendar-year BV over 2025, that outer limit is 31 December 2026.
One trap deserves its own line: in a BV where all shareholders are also directors, signing the prepared accounts can count as adoption at the same moment — which starts the eight-day filing clock immediately. The safe habit for an owner-managed BV: prepare, adopt and file in one movement.
The size classes: how much you publish
What you file depends on the company's size class, measured on balance sheet total, net revenue and headcount (meeting two of three, in consecutive years):
| Class | Balance sheet | Net revenue | Staff | You publish |
|---|---|---|---|---|
| Micro | ≤ €450,000 | ≤ €900,000 | < 10 | A condensed balance sheet — a few lines |
| Small | ≤ €7.5M | ≤ €15M | < 50 | Condensed balance sheet with notes |
| Medium | ≤ €25M | ≤ €50M | < 250 | Fuller accounts, audited |
| Large | above | above | ≥ 250 | Full accounts, audited |
The comfort in that table: the overwhelming majority of foreign-owned BVs are micro or small, publish a condensed balance sheet only — profit figures stay private — and file digitally through SBR, which any Dutch bookkeeper handles as routine. The statutory audit begins at medium.
Why late filing is the expensive mistake
Late or missing filing is an economic offence with fines attached — but the real weight sits elsewhere. If the BV later goes bankrupt and the accounts were filed late, the law presumes improper management by the board, and the trustee can hold directors personally liable for the deficit. It is one of the very few places in Dutch law where a formality pierces the BV's liability shield. The cure costs an hour a year; the disease can cost everything. This is exactly the deadline that an entity-management arrangement exists to watch.
The first financial year
A BV incorporated mid-year may choose a long first financial year — for example from a March 2026 incorporation through 31 December 2027 — set in the deed at formation. One filing covers the whole stretch, which is why the choice is made at incorporation, deliberately.
The short version
Prepare within five months (extendable), file within eight days of adoption, and in every case within twelve months of year-end. Micro and small companies publish a condensed balance sheet only; the audit starts at medium. File on time, every year — it is the cheapest liability protection a director can buy. The rest of the yearly rhythm sits in corporate services in the Netherlands.
