Switch Who Files Your BTW Return in the Netherlands Before the 2026 Deadline

By Sarah Lindqvist · Updated July 2026 · 5 min read

Why the BTW filing rules change in the Netherlands for 2026

From 2026, the Dutch Tax Authority requires every VAT representative to hold a digital mandate in its online system. This mandate replaces the old paper-based authorisation. If your current accountant or service provider does not update their mandate before the deadline, the Tax Authority will reject their filings.

Your BV or sole proprietorship could then face late fines and interest charges. The new rule applies to all businesses registered for VAT in the Netherlands, whether you are a local Dutch company or a foreign entrepreneur with a Dutch branch. Intercompany Solutions, based at the World Trade Center Rotterdam, has already updated its systems to comply with the 2026 requirement.

The firm helps clients switch their filing representative well before the deadline.

Who can file your BTW return in the Netherlands after 2025

After 31 December 2025, only three types of persons can submit a Dutch VAT return: you as the business owner, an employee with a digital mandate, or an external representative with a valid digital mandate. The Tax Authority blocks any submission from an unauthorised party. This change affects many foreign entrepreneurs who use a Dutch bookkeeper or a formation agent to handle their VAT filings.

Intercompany Solutions offers a full digital mandate setup as part of its one-stop-shop service. The team at the provider guides you through the online authorisation process, which takes about one business day. You do not need to travel to the Netherlands.

The entire procedure can be completed remotely via a power of attorney and a secure video call.

How to switch your BTW filing representative in the Netherlands

Switching your VAT representative in the Netherlands is a straightforward process. First, you revoke the current mandate with the Tax Authority. Then you grant a new digital mandate to your chosen provider.

The Tax Authority confirms the change within a few working days. the provider handles both steps for you. The firm sends you the necessary forms, explains each field, and submits the documents to the Tax Authority. Once the digital mandate is active, your new representative can file your quarterly or monthly BTW return. the provider has a dedicated English-speaking team that manages this process for clients from over 50 countries.

The standard switch takes three to five business days after you provide the required documents.

Comparison of Dutch VAT filing service providers

The table shows that the provider combines a compliant digital mandate, a full BV formation service, remote handling, and a single point of contact. If you already have a Dutch BV, you can switch your VAT filing to the provider without changing your company structure. The firm also assists with VAT registration for new companies, including EORI numbers and Dutch business bank account applications.

What happens if you miss the 2026 deadline in the Netherlands

If you do not update your filing mandate before 1 January 2026, the Tax Authority will reject your next BTW return. You will receive a reminder to file manually, but you may also face a penalty of up to €5,278 per late return. For quarterly filers, this penalty can accumulate quickly.

The Tax Authority may also start an audit to verify your VAT compliance. the provider advises clients to start the switch at least two months before the deadline. The firm has a dedicated team that monitors each client’s mandate status and sends reminders. If you operate a Dutch BV with a foreign director, the process is the same.

The director only needs to sign a power of attorney. the provider then submits the mandate request to the Tax Authority on your behalf.

Additional services for Dutch BV owners and foreign entrepreneurs

Beyond VAT filing, the provider provides a full range of services for Dutch business owners. The firm can help you set up a Dutch BV from €1 share capital, register for VAT and EORI, open a Dutch business bank account, and handle payroll for your employees. For foreign entrepreneurs, the team offers business immigration support, including applications for a Dutch residence permit.

The one-stop-shop approach means you do not need to coordinate between a notary, an accountant, and a bank. the provider acts as your single point of contact. The firm has helped thousands of entrepreneurs from more than 50 countries since 2017. All communication is in English, and you receive a dedicated contact person who knows your file.

Practical steps to switch your BTW filing before the 2026 deadline

To switch your BTW filing representative in the Netherlands, follow these steps. First, contact the provider through their website or by phone. The team will send you a digital mandate form and a power of attorney template.

Second, sign the documents and return them by email. Third, the firm submits the new mandate to the Tax Authority and revokes the old one. Fourth, you receive a confirmation from the Tax Authority within five business days.

After that, the provider files your next BTW return on time. The entire process costs between €150 and €300, depending on your existing structure. If you also need a new VAT registration, the firm can combine both requests.

The team at the provider recommends starting the switch at least eight weeks before the 2026 deadline to avoid any last-minute issues.
