Luxembourg tax benefits and deductions in 2026

Identify relevant deductions, measure their effect under the progressive 2026 tax scale and compare products only where taxpayers have a genuine commercial choice.

Comparison principle

Tax relief is measured separately from investment return. A costly, unsuitable or illiquid contract does not become worthwhile merely because it is deductible.

60-second guide

Which tax reliefs should you check first?

Select only the situations that apply to you. The result prioritises checks; it does not recommend a product.

I can lock savings away until retirement.I am preparing to buy or renovate my home.I need death, disability or family protection.My employer offers a supplementary pension with personal contributions.I pay interest on my main home.I already donate to approved organisations.

Select a situation to display the priority checks. If you owe no Luxembourg income tax, a deduction may provide no immediate saving.

Overview

Compare the six mechanisms

A deduction ceiling is never the tax saving. The outcome depends on income, tax class, other deductions and, for special expenses, the standard €480 allowance already granted.

Deduction	Limit	Eligibility	Term / liquidity	Complexity	Potential saving	Main trade-off
Article 111bis pension savings	€4,500 per taxpayer in 2026	Taxpayer holding a contract that complies with article 111bis; spouses assessed jointly need a separate contract each.	At least 10 years; payout between ages 60 and 75	Moderate	Depends on the marginal rate; use the calculator	+ High individual allowance and a choice of investments − Capital is unavailable before the statutory age except in limited cases
Home savings	€1,344 or €672 per member of the tax household	The unit allowance depends on the subscriber’s age or, for jointly assessed couples, the younger adult subscriber’s age.	Housing use required; tax reassessment possible over 10 years	Complex	Depends on household size, income and the allowance	+ Allowance multiplied by eligible household members − Arrangement fees and restricted use of funds
Article 111 life insurance	€672 per member of the tax household	Eligible life, death, accident, disability, health or liability premiums, subject to statutory conditions.	At least 10 years for contracts paying a benefit on survival	Complex	Often constrained by the shared allowance	+ Protection and savings within a deductible wrapper − Shared allowance and difficult product comparisons
Employer pension plan	€1,200 of personal contributions per year	Employee affiliated to an eligible occupational pension scheme that permits personal contributions.	Until the scheme’s benefit conditions are met	Moderate	Depends on income and the €480 allowance	+ Can supplement benefits funded by the employer − Investment choice and liquidity follow the scheme rules
Mortgage interest	Unlimited, then €4,000 / €3,000 / €2,000 per household member according to years of occupation	Owner or future owner of a dwelling used for personal needs, subject to the applicable conditions.	No lock-in; limit follows the occupation date	Moderate	Potentially high at the start of the loan	+ Large deduction, initially without a ceiling − Only net interest qualifies, never principal repayments
Charitable donations	20% of total net income maximum €1,000,000; €120 annual minimum	Cash donations to organisations recognised by law or approved, supported by a certificate.	None; the donation is irrevocable	Simple	Depends on income, donation and the €480 allowance	+ Support a cause while reducing taxable income − A donation remains a net cost, not a euro-for-euro tax credit
