Incorrect Income Reporting

Not Updating Personal Information

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.
