Whether you are an employee, self-employed, or retired, here is a practical guide to help you approach your tax declaration with peace of mind.
Why Declare Your Taxes in Luxembourg?
Filing a tax return is not just a legal obligation—it’s also an opportunity. It allows you to determine the exact amount of tax you owe based on your income, deductible expenses, and personal or family situation. When completed correctly, it can even help you reduce your tax burden through various deductions and tax credits.
Key Steps for a Successful Tax Declaration
1. Gather the Necessary Documents
- Your payslips or pension certificates
- Statements of rental income or capital gains
- Bank statements (interest, dividends, investments)
- Proof of deductible expenses (childcare costs, donations, insurance premiums, mortgage interest, etc.)
2. Understand Your Taxable Income
- Salaries and wages
- Pensions and annuities
- Real estate and investment income
- Capital gains (under certain conditions)
- Rental income
Make sure to declare everything accurately to avoid penalties from the tax authorities.
3. Identify Possible Deductions
- Childcare expenses
- Interest on mortgage loans
- Life or health insurance premiums
