Frequently Asked Questions

Find answers to common questions about Dutch taxes, DigiD, and allowances. If you can't find what you're looking for, feel free to reach out.

fingerprint DigiD Setup

What is DigiD?

expand_more
DigiD stands for Digital Identity. It's a secure login system used to access online services from Dutch government agencies, healthcare providers, and pension funds. It verifies your identity when you manage official affairs online.

How long does activation take?

expand_more
It typically takes 3-5 working days to receive the activation letter by post after your application. Once you have it, activation can be completed online right away.

Why might I need a translator for the video call?

expand_more
If you're not fluent in Dutch, a translator ensures clear communication with the authorities and avoids misunderstandings during official verification.

account_balance Tax Refunds

When is the deadline for tax filing?

expand_more
The deadline stated in your Belastingdienst invitation letter is decisive; in many cases it is May 1. If you need an extension, request it before the date shown in the letter.

What is an M-form?

expand_more
The M-form (Migration form) is a special comprehensive tax return required for the year you migrated to or emigrated from the Netherlands. It accounts separately for the resident and non-resident periods.

What is a C-form, and who needs it?

expand_more
The C-form is for taxpayers who did not live in the Netherlands for the whole year but did earn Dutch-sourced income (for example, cross-border workers). Unlike the M-form, it doesn't require a migration or emigration year — it applies to anyone who was a non-resident taxpayer during that tax year. I work out which form applies to you and prepare your filing accordingly.

How much refund can I expect?

expand_more
The result depends on your total income, payroll tax withheld, genuinely applicable deductions such as mortgage interest, and personal circumstances such as a fiscal partner or the 30% ruling. The outcome may be a refund, an amount to pay, or zero.

health_and_safety Healthcare Allowance

Am I eligible for the allowance?

expand_more
Eligibility for the healthcare allowance mainly depends on your income (and your partner's, if applicable) and total capital. You also need a mandatory Dutch health insurance policy.

How do I apply?

expand_more
I handle the whole process for you, from checking your eligibility to submitting the application to the Belastingdienst. You just send me your basic details and I take care of the rest.

analyticsZZP and Business

What do I need to start a sole proprietorship (ZZP)?

expand_more
You generally register with the KvK, after which the Belastingdienst assesses your VAT position and issues the relevant BTW numbers. For a standard registration you need a BSN and a Dutch business address. I help set up your tax and invoicing workflow after registration.

How often do I file a BTW return?

expand_more
The frequency stated by the Belastingdienst is decisive; quarterly filing is common. If you participate in the KOR, you normally do not file regular BTW returns, although exceptions can apply.

Can I do my own bookkeeping?

expand_more
Yes. You remain responsible for keeping complete and accurate records. The ZZP package combines bookkeeping, BTW returns and the annual income tax return if you prefer ongoing support.

paymentsPackages and services

Should I choose a package or an individual service?

expand_more
A package can be useful when you need several included services during the year. If you only need one transaction, an individual service is usually clearer. The scope and required documents are confirmed before work begins.

How do I know what documents are needed?

expand_more
The required documents depend on the service and your situation. Before we start, I explain the scope and the documents needed.

What happens if there is an error?

expand_more
If an error is mine, I correct it free of charge. I also continue answering questions about the submitted file and letters that relate to it.

How do family applications work?

expand_more
For a partner and children, we can prepare the required municipality-registration documents together.
