Who can benefit from tax deductions?

When you first arrive in Luxembourg and have to declare your taxes for the first time, personal taxation can be quite complex. Taxpayers can benefit from tax deductions.

To benefit from these tax deductions, the taxpayer must be resident in Luxembourg, or "assimilated Luxembourg resident" if non-resident. This is particularly the case for cross-border workers who live outside Luxembourg, but work in Luxembourg.

However, to be "assimilated", the non-resident taxpayer must meet a certain number of conditions:

  • receive at least 90% of their income from Luxembourg
  • receive less than 13,000 euros in annual income from a country other than Luxembourg
  • in the case of teleworking, income received "outside Luxembourg" will only be assimilated to Luxembourg income up to a maximum of 50 days.

Non-Belgian residents benefit from assimilation, if more than 50% of the household's professional income comes from Luxembourg. However, they must comply with the 50-day rule, otherwise the Belgian social security system will apply if they work more than 25% of their time from Belgium.

Optimize your tax situation by owning your own home

Tax deduction for interest expense on home loans

When you finance your home with a mortgage, you can deduct the interest charges on your tax return. The deduction limit depends on the date you moved in and the composition of your household. Deductions are degressive according to the number of years you've lived in the property (5 years or less, between 6 and 10 years, more than 10 years).

In the year of purchase, interest charges on a VEFA property are fully deductible. This is also the case for a dilapidated property in need of major renovation.

For the 2023 tax year, tax deductions amount to a maximum of 3,000 euros per person for the first 5 years, 2,250 euros between 6 and 10 years and a maximum of 1,500 euros per person from 10ns onwards.

From tax year 2024, these amounts are increased to 4,000 euros per person for the first 5 years, 3,000 euros between 6 and 10 years and 2,000 euros maximum from 10 years onwards.

Note that interest subsidies are deducted from the amount of deductible interest.

However, notary fees and bank charges and commissions can also be deducted from the tax return.

Deduction of premiums paid into home savings schemes

Epargne logement is an investment with a minimum term of 10 years, enabling you to finance the acquisition or conversion of your home in Luxembourg or abroad. The capital can also be used to repay a mortgage.

The maximum deduction is 672 euros per household member, or 2,688 euros for a 4-person household. This deduction is doubled for household members aged between 18 and 40, to encourage home ownership.

  • life annuities.

The ceilings vary according to the type of annuity paid during the year.

Tax deductions for donations
