20 Common Tax Mistakes to Avoid When Filing in Denmark

Denmark is renowned for its robust economy, stellar social welfare system, and high quality of life. With businesses thriving and residents enjoying a range of public services, the Danish taxation system plays a vital role in maintaining this balance. However, navigating through the Danish tax system can be complex, and both residents and foreign nationals often make common mistakes when filing their taxes. Below are 20 common tax pitfalls to avoid when filing in Denmark.

1. **Neglecting to Declare Worldwide Income**
Global income must be declared by Danish residents, including income from overseas investments, properties, or bank accounts. Failing to include this could lead to significant penalties.

2. **Missing Filing Deadlines**
Missing the tax submission deadlines can incur fines. The annual self-assessment tax return, forskudsopgørelse, typically needs to be submitted by March 1st.

3. **Wrong Residency Status**
Understanding whether you are a resident or non-resident for tax purposes is crucial as it affects your tax obligations. Residency is determined by several factors including the length of stay and ties to Denmark.

4. **Overlooking Deductions and Allowances**
Denmark offers various deductions and allowances that can lower your taxable income, including work-related expenses, contributions to pension schemes, and childcare costs. Missing these can result in overpaying taxes.

5. **Errors in Deducting Mortgage Interest**
While mortgage interest is deductible, the rules are specific. Ensure you accurately report the interest paid on your mortgage by referring to the correct forms from your bank.

6. **Misreporting Investment Income**
Investment income, including dividends and capital gains, must be correctly reported. Note the specific tax rates and reliefs applicable to these.

7. **Filing Double Tax Relief Incorrectly**
Denmark has agreements with several countries to avoid double taxation. Correctly applying for double tax relief is essential to avoid paying taxes on the same income twice.

8. **Mistakes in Business Expense Claims**
Only business expenses that are wholly, exclusively, and necessarily incurred for business purposes are deductible. Ensure these are well-documented and justifiable.

9. **Misunderstanding VAT Procedures**
If your business is VAT-registered, not adhering to VAT regulations can lead to substantial fines. Ensure accurate VAT reports and timely submissions.

10. **Failure to Register as Self-Employed**
Self-employed individuals must register with the Danish Customs and Tax Administration (SKAT) and receive their own business tax ID number. Failure to do so can delay your tax processes and incur penalties.

11. **Incorrect Submissions of Tax Cards**
Tax cards contain details about your tax rate and deductions. Inaccurate or outdated submissions can lead to incorrect tax calculations.

12. **Neglecting to Declare Rental Income**
If you rent out property in Denmark, remember to declare any rental income. This includes income from platforms like Airbnb.

13. **Errors in Foreign Pension Reporting**
Pensions from foreign sources must also be declared. Ensure that these are correctly reported to avoid tax discrepancies.

14. **Misunderstanding Carry Forward Losses**
Losses can often be carried forward to future years for tax relief. Understanding the rules regarding this can prevent you from missing out on legitimate tax benefits.

15. **Improper Motor Tax Payments**
Vehicle owners in Denmark must pay green taxes on their cars. Incorrect or late payments can result in additional fines.

16. **Misreporting Donations to Charities**
Only donations to approved charities are tax-deductible. Ensure that your charitable contributions meet the required criteria before claiming deductions.

17. **Missing Out on Work-From-Home Deductions**
If you work from home, certain expenses can be deducted. Ensure that you maintain clear records and meet the qualifying criteria.

18. **Incorrect Reporting of Stock Options**
Stock options provided by employers must be appropriately reported at the time of exercise to ensure correct tax treatment.

19. **Errors in Foreign Bank Account Reporting**
Declare balances in foreign bank accounts accurately. Failure to do so can draw severe penalties.

20. **Inaccurate Income Splitting**
Income splitting between spouses should be done following the Danish tax rules to ensure compliance and efficiency.

Proper tax filing is significant for the smooth operation of finances in Denmark, whether you are a resident, a business owner, or a foreigner. Understanding and avoiding these common mistakes can safeguard against penalties, ensure compliance, and potentially lead to tax savings. When in doubt, consulting a tax professional who understands Danish tax legislation is always a prudent approach.
