Give the house now, or leave it later?

The premise

If you compare the two routes by tax rate alone, you miss what time limits, adding-up rules, the number of recipients and civil law do to the result.

That’s a condition, not a conclusion. This piece doesn’t say that giving beats inheriting, or the other way round.

Three things people say

Picture older parents who own their home. They plan to pass it on and would like to pay less tax, but aren’t sure how. Before they see a notary, they tend to hear three things:

• Leave it until you die, and the tax is 30%.
• Give it while you’re alive, and it’s 3% — or nothing at all.
• If you die too soon after giving it, there’s trouble.

How far does each of these hold? We checked them against the tax authorities and legislation of Brussels, Flanders and Wallonia, and worked through the figures for a hypothetical €350,000 house.

This piece shows how the rules work and what they add up to. It doesn’t tell anyone what to do: a real plan is for a notary to draw up, with the family’s documents in front of them.

Which region’s rules apply

Gift and inheritance tax are set by the regions. But what decides which region’s rules apply isn’t where the house is. According to the federal finance ministry, it is where the person making the gift has had their tax residence over the past five years — or, if they have moved, wherever they lived longest in that time. Inheritance tax works the same way, based on the person who died.

Where the rules differ from one region to another, you can switch between them below. Brussels is shown first.

“30%” is only the top band

Inheritance tax isn’t charged on the estate as a whole. It’s charged on each heir’s share, at rates that rise in bands. A 30% rate, where there is one, applies only to the top slice of that share.

“3% or nothing” is about cash

Give cash and register the gift, and Brussels and Flanders charge a flat 3%, Wallonia 3.3%. Hand it over or transfer it without registering it, and no gift tax is due.

A house is different. Giving one requires a deed signed before a notary, and that deed is registered, so there’s no avoiding gift tax. Nor is it a flat 3%. All three regions use the same scale:

Value going to each recipient	Rate
Up to €150,000	3%
€150,000 to €250,000	9%
€250,000 to €450,000	18%
Above €450,000	27%

In Wallonia, deeds signed from 1 January 2028 will be taxed at 3, 6, 10 and 14%.

Giving our €350,000 house to one child in one go costs €31,500 in gift tax. Split it between two children and each receives €175,000, for a total of €13,500. If a couple own the house jointly and give it to two children, that’s four separate gifts, costing €10,500 in all. The reason is that the rates apply to each recipient separately. For a Walloon deed signed in 2028 or later: €20,500 for one child, €12,000 for two.

What about including grandchildren? They are taxed at the same direct-line rates as children. The Flemish tax authority defines the direct line as parent and child, and also grandparent and grandchild; the federal finance ministry’s definition runs from grandparents to parents, children and grandchildren.

Recipients	Each receives	Total gift tax
1	€350,000	€31,500
2	€175,000	€13,500
3	about €116,700	€10,500
4	€87,500	€10,500
6	about €58,300	€10,500

There is a floor, though. The 3% band stops at €150,000 per recipient. Once there are three recipients, every share falls within it, and adding more people won’t bring the tax below 3% of the house’s value: €10,500. Compared with giving the house to two children, bringing in grandchildren saves at most €3,000. The three-year rule adds up gifts between the same giver and the same recipient, so spreading a gift across more people isn’t caught by it.

Some things change beyond tax. A grandchild whose parent is still alive is usually not an heir, so under civil law, as we read it, what they receive would be measured against the children’s protected share rather than evened out between brothers and sisters. A deed in favour of someone who isn’t an heir uses a more expensive notary fee scale. And the more owners there are, the more people must agree before the whole house can be sold.

By law, the recipient owes the gift tax. The Flemish tax authority says so, adds that the parents can agree to pay it instead, and says the tax paid that way doesn’t count as part of the gift. Notary fees come on top: on the official scale, a single €350,000 deed costs about €949, before VAT and administrative costs.

“Dying too soon” depends on what was given

The tax rules have windows of five and three years; civil law has none. When a parent dies, gifts made during their lifetime are brought back into the calculation, however long ago they were made. That is where the evening-out between siblings, and the reduction of gifts that go beyond the children’s protected share, come from. The children’s protected share is half of the estate as calculated, however many children there are. And a house given with the right to live in it kept back is counted at its value on the day the parent dies, not on the day it was given.

Giving a share each year

We worked through one approach: each year, the parent gives one child half of whatever share of the house they still own. In all three regions, gifts of real estate between the same people within three years are added together when the rate is set.

Year	Share given	Gift tax that year	Running total
1	€175,000 (half the house)	€6,750	€6,750
2	€87,500 (half of what’s left)	€9,000	€15,750
3	€43,750 (half of what’s left)	€7,875	€23,625

After three years, the child owns 87.5% of the house. Giving that same 87.5% in one go costs exactly the same: €23,625. Three deeds instead of one push notary fees from about €929 to about €1,650. And however many times the share is halved, a sliver stays with the parent — worth €43,750 after three years — and it passes on as an inheritance.

Gift tax is paid once per deed; it doesn’t come back each year on what has already been given. What’s left is that sliver, and the tax on it depends heavily on when the parent dies.

The within-three-years figures are our own calculation: the tax on the combined value, minus the tax on the part already given. How Wallonia applies its tax-free amount in this case is unconfirmed.

Keeping the right to live there

Parents can also keep the right to go on living in the house — a usufruct — and give the children only the ownership. That doesn’t make the gift tax any lower: when a usufruct is kept back, the taxable value can’t be less than the value of full ownership. Federal registration law and Flemish tax law both say so, which means the figures above still apply.

We found no provision taxing the usufruct when it ends on the parent’s death, and the notaries’ federation says no further tax is due. If the parents keep only a right of habitation, civil law lets them live in the house but not rent it out.

Where insurance comes in

Families are sometimes advised to use insurance. The structure we could confirm is this: when the person who died had taken out a life insurance policy and named a beneficiary, article 8 of the inheritance tax code treats the payout as a bequest. That is the case in all three regions. And since 1 January 2026, the new 10% tax on capital gains from financial assets also reaches both guaranteed-return (branch 21) and investment-linked (branch 23) policies.

The financial regulator, the FSMA, has reviewed the costs of investment-linked policies and got insurers to cut them on a number of products. We found no official survey of why people buy these policies, so this piece doesn’t guess.

At a glance: a €350,000 house

The assumptions: one parent owns the house alone, the children are adults, there are no other assets or debts, and notary fees and costs are left out. Gift tax is charged on the house’s value on the day of the gift; inheritance tax on its value on the day of death. If the house gains 2% a year, it would be worth about €426,650 in ten years, and one child’s inheritance tax would then be about €67,700 in Brussels and €67,200 in Flanders.

The table doesn’t say which route is better. The parents’ circumstances, fairness between siblings and the time that passes after a gift don’t show up in the figures.

What this piece does not claim

• That giving is better than inheriting, or the reverse
• That any particular plan suits any particular family
• That anyone should or shouldn’t buy an insurance product
• That Wallonia’s 2028 cuts will take effect as passed

What we checked, and what we couldn’t

Checked

• Gift and inheritance tax follow the region where the giver (or the person who died) had their tax residence over the past five years — federal finance ministry
• Gift tax on a house in the direct line — in all three regions, 3% up to €150,000, 9% up to €250,000, 18% up to €450,000 and 27% above that. In Wallonia, 3, 6, 10 and 14% for deeds signed from 1 January 2028 (decree of 5 December 2024)
• The five-year rule for unregistered cash gifts — for gifts made from 1 January 2022 in Wallonia, 2025 in Flanders and 2026 in Brussels; earlier gifts keep three years
• Inheritance tax rates and tax-free amounts in the direct line — as in the tables above. Top rate 27% in Flanders, 30% in Brussels and Wallonia, 15% in Wallonia for deaths from 2028
• Real-estate gifts between the same people within three years are added together, in all three regions. The rule applies to the same giver and the same recipient, and a second gift is taxed from the band where the earlier one ended — Flemish tax authority
• Grandchildren are in the direct line — Flemish tax authority, federal finance ministry
• Gift tax is paid once per deed. A deed in favour of someone who isn’t an heir uses a more expensive notary fee scale — 1950 fee scale
• Selling the whole house requires the agreement of every co-owner — Civil Code, Book 3
• The effect of a house gift made within three years before death on inheritance tax — it exists in Flanders and Wallonia, and was abolished in Brussels for gifts from 2016
• When a usufruct is kept back, the taxable value can’t be less than full ownership — federal registration law, Flemish tax law
• The recipient pays the gift tax, and the parents can agree to pay it instead — Flemish tax authority
• The children’s protected share is half of the estate as calculated, and a gift with the right to live there kept back is counted at its value on the day of death — Civil Code, Book 4
• A payout to the beneficiary of a policy taken out by the person who died is treated as a bequest — article 8 of the inheritance tax code, all three regions. The capital gains tax on financial assets reaches insurance from 1 January 2026
• Our method reproduces the federal finance ministry’s official Walloon example (a child aged 17 and a half inheriting €150,000 pays €9,950)

Couldn’t check

• Who owes gift tax in Brussels and Wallonia, and whether parents paying it counts as an extra gift there
• How the three regions tax a gift where only a right of habitation is kept
• A legal provision confirming that no tax is due when a usufruct ends on death
• Whether Wallonia’s 2028 cuts will take effect as passed
• When the three-year period starts, and how Brussels and Wallonia continue the rate on combined gifts — our figures follow the Flemish method
• How the tax on the remaining share is worked out if a parent dies within three years of the last gift, and how Wallonia applies its tax-free amount — our figures are an interpretation
• How gifts to grandchildren are settled under civil law, and the formalities for minor grandchildren
• The rate on the part of a Brussels family home above €250,000 — our figures continue the general scale
