Follow these 8 steps to complete your tax return:
Access the online tax portal using your DigiD credentials. If you don't have DigiD, register at digid.nl first.
Check all pre-filled data for accuracy. The Belastingdienst receives data from employers, banks, and municipalities.
Enter any income or deductions not pre-filled by the system.
If you have a fiscal partner, decide how to allocate shared income and deductions for optimal benefit.
Ensure all three tax boxes are complete and accurate.
Review and claim all eligible deductions and tax credits.
Review the summary, sign digitally, and submit your tax return.
Monitor processing status and await your assessment letter.
Maximize your refund by claiming all eligible deductions:
Deduct mortgage interest for your primary residence. Benefit decreases annually (2025: 36.97% of interest)
Deduct healthcare costs above €154 plus 5.75% of your income. Includes specific treatments, medication, and medical devices.
Donations to registered charities (ANBI) above €60 qualify for 125% deduction in tax calculation
Standard deduction for work expenses (werkgerelateerde kosten). No receipts needed for amounts under threshold.
Deduct education costs for career advancement: tuition fees, books, required equipment, exam fees
Deduct childcare expenses (gastouder, daycare) with maximum deduction of €8,424 per child annually
Private pension contributions (annuities, lijfrente) are fully deductible from taxable income
Understanding how your income is taxed:
Tax on dividends and capital gains from substantial interest (>5% ownership in company)
Progressive wealth tax on net assets above €57,000 (€114,000 for couples)
Rates vary based on asset composition (savings vs. investments)
Prevent these frequent errors when filing:
Filing after May 1 may result in penalties up to €5,664. Request extension before deadline if needed.
Don't leave money on the table. Review all eligible deductions including healthcare, donations, and study costs.
Report all income sources including foreign income, freelance work, and investment income. Errors can trigger audits.
Update address changes, marital status, and children. Wrong information delays processing and refunds.
Must report worldwide income even if taxed abroad. Foreign tax credits available to avoid double taxation.
If you paid tax abroad, claim foreign tax credit to reduce double taxation on same income.
Optimize income and deduction allocation between partners. System suggests best split but you can adjust.
Keep receipts and statements for 5 years. Belastingdienst may request proof of deductions later.
Guidance for specific circumstances:
New to Dutch taxes? Register for DigiD, gather all documents, consider using tax advisor for first filing. Pre-filled data may be limited.
Partial year residents file proportional taxes. Report foreign income for full year. Qualify for partial general tax credit.
Include profit/loss statement, deduct business expenses, pay income tax on profit. May need separate VAT filing.
30% of salary is tax-free. Report full gross salary but tax calculated on 70%. Can opt for partial non-resident status.

Report rental income in Box 1 if active rental. Deduct maintenance, management fees, mortgage interest proportionally.
Fiscal partnership changes mid-year. File separately for each period. Allocate shared expenses proportionally.
