What each family covers
Value added tax. A super-reduced rate applies to creation and renovation works on a dwelling used as a main residence. The benefit takes the form of a lower invoice, with no payment made.
Acquisition duties. A tax credit reduces the duties owed on purchasing a dwelling intended for personal occupation. The benefit is applied at the time of the deed.
Grants and subsidies. Support targets specific items, notably energy refurbishment and equipment. The benefit takes the form of a payment or an invoice deduction.
Financing support. Mechanisms bear on the loan itself, notably as an interest subsidy or a guarantee. The benefit spreads across the life of the loan.
Authority and moment
Each family has its counterpart and its deadline, and confusing them causes missed dates. They fall to separate administrations.
| Family | Who decides | When to apply |
|---|---|---|
| Value added tax | competent tax administration | before works begin |
| Acquisition duties | tax administration, via the notary | at the time of the deed |
| Grants and subsidies | housing or energy administration | scheme-dependent, generally before commitment |
| Financing support | housing administration, with the lender | before or on setting up the loan |
No single desk covers all four, which means running the steps in parallel.
Relief or payment
A distinction that changes cash flow and that comparisons ignore. Some benefits are immediate, others deferred.
Relief does not pass through the beneficiary's account. The invoice is simply lower, or the duties smaller. There is nothing to advance.
A payment often means having paid first. The support arrives afterwards, with a lag.
Some arrangements have moved towards direct deduction, sparing the beneficiary from advancing sums, covered in the article on energy refurbishment support.
Practical consequence: two schemes of equal amount do not have the same effect on a funding plan, and they must be distinguished in a budget.
Who lodges the application
A point that surprises and causes files to be missed. One project may fall under several families at once.
The beneficiary is not always the applicant.
For direct application of the reduced tax rate, it is the professional carrying out the works who lodges the approval request, with the owner countersigning.
For acquisition duties, it is the notary who makes the application at the time of the deed.
For grants, it is generally the beneficiary, sometimes with the installer's involvement.
An owner waiting to be asked may therefore miss a scheme entirely, for not having flagged their situation to the right counterpart.
How to spot which apply
Four questions, to ask at the start of the project. They identify which schemes can be used.
Will the dwelling be occupied as a main residence, and by whom.
Is this a purchase, a build, a refurbishment, or a combination, the regimes differing.
Do the works include an energy component opening specific schemes.
Is the project financed by a loan, which opens the fourth family.
What this means for a professional
Four rules.
Treat the four families separately, they share neither authority nor timetable.
Identify who lodges each application, and tell the client.
Distinguish relief from payment in any funding plan issued.
Do not assume one counterpart will mention the other schemes, none covering them all.
