In Luxembourg, taxpayers have the opportunity to reduce their taxable income through certain expenses incurred during the tax year. These deductions are divided into two main categories: special expenses and extraordinary expenses. Discover the key points below.

1 – Special expenses: everyday benefits

Special expenses include common costs incurred by most households, such as insurance premiums or pension plans. These deductions are subject to limits depending on the type of expense and the number of people in the household.

Insurance: protection with a tax advantage

Premiums paid for various insurance contracts (life, death, supplementary health, liability insurance, etc.) are deductible up to €672 per dependent. For single-premium policies, such as balance insurance, the limit may be increased depending on age and family circumstances.

Pension savings: preparing for the future

Contributions to pension savings plans, with a minimum duration of 10 years, are deductible up to €3,200 per year. These plans allow for benefits in the form of lifetime annuities or, in part, as a lump sum.

Home savings plans: support for becoming a homeowner

Premiums paid for home savings contracts are deductible up to €1,344 per year for taxpayers under 40 years old and €672 for those above this age. These amounts apply per dependent in the household.

Other deductible expenses:

  • Group insurance: personal contributions to supplementary pension plans are deductible up to €1,200 per year.
  • Loan interest: interest on personal loans is deductible up to €672 per dependent.
  • Donations: donations to recognized public utility organizations are deductible starting from €120 and up to 20% of net income or €1,000,000.

Standard deduction

A minimum deduction is automatically applied: €480 per taxpayer or €960 for jointly taxed couples, unless actual expenses exceed this threshold.

2 – Extraordinary expenses: managing the unexpected

Extraordinary expenses relate to exceptional or unavoidable situations, often unforeseen, that can impact a household’s financial capacity.

Examples of deductible extraordinary expenses:

  • Family obligations: costs for educating children outside the household or supporting parents in financial difficulty (limit of €4,422 per child).
  • Childcare or household help: limit of €5,400.
  • Health: medical expenses or costs related to disabilities, serious accidents, or other expenses not covered by insurance.
  • Unexpected events: floods, fires, or thefts not covered by insurance.

The ability to deduct these charges depends on taxable income and household composition.
