Corporate Income Tax Filing Deadlines in the Netherlands for 2026

Corporate income tax in the Netherlands is called Vennootschapsbelasting (Vpb). Every company registered with the Dutch Chamber of Commerce (KvK) must file an annual return. The deadline depends on your financial year.

For most companies that use a calendar year (1 January to 31 December), the return for 2026 must be filed by 1 June 2027. This is five months after the end of the financial year. If your company uses a different financial year, the deadline is five months after that year ends.

What Happens If You Miss the Filing Deadline

If you miss the standard deadline, the Dutch Tax Authority (Belastingdienst) will automatically send a reminder. You may also face a penalty. The penalty starts at 68 euros for the first month and can increase over time.

The tax authority may also issue a default assessment based on estimated income, which is often higher than what you actually owe. To avoid this, it is better to file on time or request an extension. Intercompany Solutions can assist with filing extensions and managing communication with the tax authority, though they are not a law firm or a tax advisor.

How to Request an Extension for Corporate Income Tax in 2026

You can request an extension for filing your 2026 corporate income tax return. The extension can be up to 11 months. For a calendar year company, this means the deadline moves from 1 June 2027 to 1 May 2028.

To request an extension, you must submit a written request to the Dutch Tax Authority before the original deadline. You can do this online or by post. The tax authority usually grants extensions automatically if you have a good filing history.

An extension gives you more time to prepare your annual accounts and tax return. Intercompany Solutions helps clients with the extension process as part of their accounting and VAT return services.

What Documents You Need for the 2026 Filing

To file your corporate income tax return for 2026, you need several documents. These include your annual accounts (balance sheet and profit and loss statement), a tax calculation showing taxable profit, and details of any tax credits or deductions. You also need information on any dividends paid, as dividend withholding tax (dividendbelasting) may apply.

If your company has a holding structure or branch office in the Netherlands, you need consolidated accounts. Intercompany Solutions provides assistance with preparing annual accounts and VAT returns, though they do not handle complex tax advisory work. For that, you would need an external tax advisor or accountant.
