Common Mistakes to Avoid
Prevent these frequent errors when filing:
Missing the Filing Deadline

Forgetting to Claim Deductions
Don't leave money on the table. Review all eligible deductions including healthcare, donations, and study costs.
Incorrect Income Reporting
Report all income sources including foreign income, freelance work, and investment income. Errors can trigger audits.
Not Updating Personal Information
Update address changes, marital status, and children. Wrong information delays processing and refunds.
Ignoring Foreign Income
Must report worldwide income even if taxed abroad. Foreign tax credits available to avoid double taxation.
Forgetting Foreign Tax Credits
If you paid tax abroad, claim foreign tax credit to reduce double taxation on same income.
Wrong Tax Partner Allocation
Optimize income and deduction allocation between partners. System suggests best split but you can adjust.
Not Keeping Documentation
Keep receipts and statements for 5 years. Belastingdienst may request proof of deductions later.
