How much will you keep?
Self-employed in Luxembourg
Your activity & VAT
Liberal professions don't pay municipal business tax. Commerce / craft does.
Your CCSS situation
Help us check that what CCSS bills you matches what you'll actually earn. CCSS uses its own annual terms — these don't follow the Period toggle below.
No problem — we'll show the full CCSS as what to set aside. If you do know your numbers later, this section will give a clearer picture of what's already paid vs what's owed at year-end.
Income
Rental income, investments, side income — anything taxable that isn't freelancer revenue.
Business expenses
Software, fuel, gear, professional services… Type a total or break it down below.
Include VAT in the amount — you can't recover it under this regime.
Your situation
Tax class 1 / 1a / 2 in plain language.
