BSN, DigiD and tax forms Netherlands: guide for expats
Dutch taxes with your BSN and DigiD. Guide to tax returns (aangifte), deductions for internationals, and deadlines.
What you need to know
From understanding the Dutch tax system to claiming your deductions as an expat, this guide covers what you need to know about filing taxes in the Netherlands with your BSN and DigiD.
Dutch taxes are manageable with the right information. With your BSN and DigiD, you can handle your Dutch tax obligations and claim your deductions as an international resident. This guide covers annual tax returns (aangifte), common deductions for expats and students, and corrects the most common deadline mistakes (the deadline is May 1, not April 1).
Your BSN and DigiD are required for Dutch tax filing. Most expats need to file annually if they had any income. The final deadline is May 1 (many sources incorrectly list April 1), though filing by April 30 gets you an assessment by July 1. This guide walks through the process, timeline, deductions, and corrections to common misinformation.

BSN and DigiD for tax filing: the foundation
Why you need BSN and DigiD for taxes
Your BSN (Burgerservicenummer) and DigiD are required for all Dutch tax matters:
- BSN: Your unique taxpayer identification number
- DigiD: Secure digital access to government tax services
- Combined: Enable online tax filing and communication with Belastingdienst
Critical timeline correction
BSN timeline: 2-5 weeks after registration (not same-day). DigiD requires your BSN first, then takes 1-2 weeks to activate. Plan accordingly.
Setting up DigiD for tax filing
Requirements:
- Valid BSN number (must have this first)
- Dutch registered address
- Dutch phone number (recommended)
Setup process:
- Apply at DigiD.nl with your BSN
- Receive activation code by mail (1-2 weeks)
- Activate with SMS verification or DigiD app
- Access Mijn Belastingdienst (My Tax Administration)
Helpful tip: Download the DigiD app for faster, more secure access to tax services.
Dutch tax system overview: understanding the boxes
The three-box system explained
The Dutch tax system categorizes income into three "boxes," each with different rates:
Box 1: Employment & Housing Income
What's Included:
- • Salary and wages
- • Freelance income
- • Unemployment benefits
- • Pension income
- • Rental income from main residence
Box 2: Substantial Business Interest
What's Included:
- • Dividends from 5%+ company ownership
- • Capital gains from substantial interest
Box 3: Savings & Investments
What's Included:
- • Savings accounts
- • Investment portfolios
- • Second homes and rental properties
- • Other assets minus debts
Tax-Free Thresholds:
• Single: €59,357
• Fiscal Partners: €118,714
Note about 30% ruling and Box 3
Since 2025, expats with the 30% ruling cannot opt for partial non-resident status (a technical provision that rarely applied to most expats). This change primarily affects expats who:
- • Have significant foreign savings and investments
- • Previously used partial non-resident status (uncommon)
- • May now be taxed on worldwide assets in Box 3
For most expats with the 30% ruling, this change has minimal impact. Consult a tax advisor if you have foreign assets over €59,357.
Tax deadlines and requirements 2026
Two dates people confuse
1 April and 1 May are both real, and they do different things. Guides that call 1 April "the deadline" have conflated them, and this page did the same until 11 September 2026.
- • 1 March: the return opens in Mijn Belastingdienst
- • 1 April: not a deadline. File before this date and the Belastingdienst guarantees a reply before 1 July. Miss it and your return is still fine, you just wait longer for the assessment
- • 1 May: the actual deadline. Also the last day to request an extension
- • 1 September: the deadline if you requested an extension before 1 May

Critical tax calendar
| Date | Deadline | Action |
|---|---|---|
| March 1 | Filing opens | Tax return portal becomes available |
| April 1 | File by here for an early answer | Belastingdienst guarantees a reply before 1 July if your return is in before 1 April |
| May 1 | Final deadline | Last day to submit without extension |
| September 1 | Extended deadline | If you requested extension by May 1 |
Important: Late filing without approved extension results in fines starting at €469 (up to €6,709 for repeat offenders).

Common deductions for internationals
Major tax deductions available
Specific healthcare costs (specifieke zorgkosten)
Costs your insurer does not reimburse. Deductible only above a threshold set by your income: €166 under €9,680 (€332 with a fiscal partner, on joint income), 1.65% of income up to €51,411, then €848 plus 5.75% of everything above that. The eigen risico does not count.
Partner alimony (partneralimentatie)
Payments to a former spouse under a formal agreement. There is no maximum amount, but above €78,426 of income the deduction is limited to a 37.56% rate rather than your top rate.
Charitable donations (giften)
Gifts to ANBI-registered charities. You deduct only the part above 1% of your threshold income (at least €60), capped at 10% of that income.
Public transport commute (reisaftrek)
Only if you commute by public transport over 10 km each way, at least one day a week or 40 days in the year. Any travel allowance from your employer comes off the total first, which for most employees leaves nothing to claim.
Mortgage interest (hypotheekrenteaftrek)
Interest on the loan for the home you live in. The largest deduction most expats have. See the dedicated section below.
What you cannot deduct
These come up constantly, and guides written for other countries often say otherwise.
- •Study costs and other training expenses. The scholingsuitgaven deduction was abolished on 1 January 2022. The STAP budget that replaced it was itself scrapped in 2024.
- •Work expenses as an employee: professional clothing, tools, memberships, or a home office. The Netherlands has no general employee expense deduction. Your employer can reimburse some costs tax-free under the werkkostenregeling, but you cannot claim them yourself.
- •Commuting by car or bike. Only the public transport deduction above exists.
- •The eigen risico on your health insurance, and the premium itself.
Mortgage interest deduction
Eligible properties:
- • Primary residence in Netherlands
- • Maximum 30 years deduction period
- • Annuity mortgage requirement for new mortgages
Important for expats:
- • Foreign mortgage interest generally not deductible
- • Property must be Dutch tax residence

Common questions
Do I need a BSN to file a Dutch tax return?
Yes. The BSN is how the Belastingdienst identifies you, and the online return is pre-filled against it. You also need a DigiD to log in. The activation code arrives by post, normally within three working days and up to five, so arrange it before the deadline rather than on it.
When is the Dutch tax return deadline?
Filing opens on 1 March and the final deadline is 1 May. File before 1 April and the Belastingdienst guarantees a reply before 1 July. If you request an extension before 1 May, the deadline moves to 1 September.
What are Box 1, Box 2 and Box 3?
Dutch income tax is split into three boxes. Box 1 covers employment and housing income, Box 2 covers substantial business interest, and Box 3 covers savings and investments. Each box is taxed at its own rate, and losses in one box cannot offset gains in another.
What are the 2026 income tax rates?
Income between €38,883 and €78,426 is taxed at 37.56%, and income above €78,426 at 49.50%. The 30% ruling, if you hold it, reduces the taxable portion of your salary before these rates apply.
Which deductions can expats usually claim?
Mortgage interest on the home you live in is the largest for most people. Others are specific healthcare costs above an income-based threshold, alimony to a former partner, gifts to ANBI charities above 1% of your income, and public transport commuting over 10 km each way.
Can I deduct study costs or work expenses as an employee?
No to both. The study costs deduction was abolished on 1 January 2022, and the STAP budget that replaced it was scrapped in 2024. The Netherlands also has no general employee expense deduction, so professional clothing, tools, memberships and a home office are not claimable. Your employer can reimburse some of these tax-free under the werkkostenregeling, but you cannot deduct them yourself.
Can I file in English?
The Belastingdienst portal is in Dutch. You can work through it with a translation tool, or use an English-language filing service, which typically costs €75 to €149 for a straightforward return.
