Luxembourg Housing Tax Reliefs and Buyer Support Since 2024: Active vs Expired in 2026

This is a current (2026) guide to the housing tax reliefs and buyer-support measures Luxembourg introduced since 1 January 2024 — the paquet de mesures en vue de la relance du marché du logement (law of 22 May 2024), backdated to the start of 2024. Several measures were deliberately temporary and have since expired; two of the most valuable were made permanent. Every status below reflects the position as of July 2026, with what each measure is worth, who qualifies, the dates it applied, and whether it is still available.

At a glance: what is still active and what expired

If you are buying your own home: the Bëllegen Akt credit (active, permanent)

The "Bëllegen Akt" is a tax credit that offsets the registration and transcription duties — 6% + 1% = 7% of the price — that you owe when you buy a home to live in. It applies to those duties only; it does not cover notary fees or other acquisition costs.

• The package temporarily raised the ceiling from €30,000 to €40,000 per buyer for deeds signed from 1 January 2024, later extended to 30 June 2025.
• It was then made permanent by the law of 3 July 2025: €40,000 per person, up to €80,000 for a couple who each acquire a share, for deeds from 1 July 2025 onward. A minimum of €100 in duties is always retained.
• Who qualifies: you must occupy the home as your main residence within 2 years (4 years for building land) and keep it as your main home for a continuous minimum of 2 years.

Because €40,000 of credit cancels the 7% duty on a price up to about €571,000 (single) — and €80,000 does so up to about €1,142,000 (a couple) — many first purchases owe little or no registration duty, depending on the price and your circumstances. Status: active and permanent.

How the credit works — a worked example

Take an illustrative €600,000 apartment bought as a main home. The 7% duties come to €42,000. A single buyer's €40,000 credit cuts that to €2,000; a couple, each acquiring half, pool an €80,000 credit and therefore pay only the €100 minimum. The credit is thus worth tens of thousands of euros on a typical purchase — though notary fees (roughly 1–2%) sit on top and are not covered. For context, chathome.lu currently lists a median asking price of €699,000 across its 5,549 active apartments for sale (computed 2026-07-16); these are asking prices for the platform's current for-sale mix and run higher than achieved transaction prices, so treat them as an upper-bound anchor, not a valuation.

If you were buying to rent: two reliefs that have expired

The 2024 package tried to pull investors back into new-build (VEFA) supply. Both headline investor reliefs were temporary and are gone:

• A new €20,000 Bëllegen Akt credit on registration/transcription duties for property bought to let to a tenant — €20,000 per investor. It covered only deeds signed in 2024 and was not extended. The exact letting conditions (minimum lease term and the delay within which the home must be rented) are set by the law of 22 May 2024. Status: expired.
• Accelerated depreciation on new-build rental housing raised to 6% a year for 6 years, capped at €250,000 of depreciation per year, for units acted in 2024 (the window was later aligned to the 2025 cut-off). Status: expired. The permanent regime remains: a 4% accelerated rate for dwellings completed less than five years ago (then 2%), plus a special real-estate allowance of 1% of the depreciation base, capped at €10,000 a year. Those permanent reliefs are still available.

If you are selling: the quarter-rate capital-gains window has closed

Normally, a taxable property capital gain — on a second home or investment, since a main-residence sale is already exempt — held more than five years is taxed at half your global rate, up to roughly 21%. The package temporarily cut this to a quarter of the global rate: 10.5% in the top bracket, per the Administration des contributions directes.

• In force: gains on disposals from 1 January 2024 to 30 June 2025, extended so that a reservation contract registered by 30 June 2025 with the notarial deed signed by 30 September 2025 still qualified.
• A worked example: on a €150,000 taxable gain, the temporary 10.5% rate meant €15,750 of tax; under the normal half-rate that same gain could cost up to about €31,500. Because the window closed, a 2026 seller reverts to the half-rate — so the relief roughly halved the bill only while it lasted. Status: expired.

A related, time-limited relief let sellers defer (immunise) a gain reinvested into social-rental-managed housing or energy-class A+ homes.

If you own and have a mortgage: interest is now more generous (active)

The reform reworked how much mortgage (debit) interest you can deduct on your main residence. Instead of a ceiling that stepped down with your years of occupancy (the old €2,000 / €1,500 / €1,000 per person), from tax year 2024 the per-person ceiling is set by the home's availability date:

• first available after 31 December 2022 → fully deductible, no ceiling;
• available 2019–2022 → €4,000 per person; 2014–2018 → €3,000; before 2014 → €2,000.

Ceilings are per person in the household (doubled for a jointly taxed couple, plus each child). For example, a couple who buy a newly built flat made available in 2024 can deduct all their mortgage interest — say €18,000 in a year — against taxable income, whereas the old rules would have capped the couple at €4,000 in the first years. Status: active (structural).

If you let a home affordably: the 90% social-rental exemption (active)

If you let a home through an approved social rental management body (gestion locative sociale, GLS), the package raised the income-tax exemption on the net rental income from 75% to 90%, from tax year 2024. A landlord earning €14,400 net through a GLS body now has only €1,440 taxable instead of €3,600, because the exemption climbed 15 points. Status: active (structural).

Cash help: the State guarantee and subsidies were raised (active)

For buyers without a large deposit, the direct aids were widened:

• State guarantee (Garantie de l'État): now covers up to 40% of project cost (raised from 30%), capped at €303,862, so eligible households can borrow without their own cash deposit. Net-income ceilings: €101,874.03 (single borrower) and €141,048.97 (multiple borrowers).
• Interest subsidy (subvention d'intérêts): maximum subsidised rate raised from 2.45% to 3.5%, on new and existing loans.
• Purchase and savings premiums (primes d'accession / d'épargne): income limits lifted, which the government estimated widened the eligible pool of households by about 59%.
• Rent subsidy (subvention de loyer): the per-child top-up was doubled from €40 to €80 a month.

Status: active.

Supply side: the State as buyer (active, multi-year)

The State also committed to buy unsold new-build (VEFA) units from developers and channel them into affordable stock, with a 2024–2027 envelope of €480 million for about 800 dwellings, alongside a broader affordable-housing fund exceeding €900 million for 2024–2026. Status: active (multi-year).

What this means for you today

The net picture depends on who you are. If you are buying your own home, the two durable wins — the €40,000-per-person Bëllegen Akt credit and fully deductible mortgage interest on a recent home — are permanent, so they still shape your budget. If you were investing or selling, the sweeteners (the €20,000 rental credit, the 6% depreciation, the 10.5% capital-gains rate) were one-off and have lapsed, which is why 2024–2025 saw a rush of investor deeds. Outcomes always depend on your own income, the property and the timing, so confirm your position with the official Administration des contributions directes or a notary.
