Determining Your Tax Residency Status

Your residency status affects which income must be reported. Residents report worldwide income, while non-residents report only Dutch-sourced income. Correct classification is crucial for accurate tax calculation and eligibility for deductions.

Collecting Required Documentation

Gather all relevant documents, including annual income statements, payslips, bank statements, and receipts for deductible expenses. Freelancers or self-employed individuals should also include VAT (BTW) records and invoices. Organized documentation simplifies filing and reduces errors.

Reporting Income Accurately

All income earned in the Netherlands must be reported, including salaries, freelance earnings, and benefits. Cross-border workers should also consider any foreign income that affects Dutch tax obligations. Accurate reporting reduces the risk of audits or penalties.

Claiming Deductions and Tax Credits

Dutch tax law allows deductions for work-related costs, mortgage interest, and other eligible expenses. Tax credits, such as the general tax credit and labor tax credit, reduce the total tax liability. Correctly claiming these deductions and credits maximizes potential refunds.
