IMT exemption for property resale in Portugal: the one-year rule

Who the resale exemption is actually for

Article 7 of the Portuguese IMT Code is aimed at acquisitions made for resale by a buyer carrying on a property-resale activity. The activity declaration must have been submitted before the acquisition. Simply deciding after completion that a property will be sold again does not create the exemption.

The tax records and transaction documents should consistently show the intention to resell. Before bidding, ask a certified accountant or tax lawyer to confirm that the activity, purchase and planned resale meet the current rules.

Two routes: exemption at purchase or repayment after resale

A buyer recognised as habitually carrying on the resale activity may obtain the exemption at acquisition. Under the current wording, that status is evidenced by a Portal das Finanças certificate showing that properties acquired for resale were resold in each of the previous two years.

A business that does not meet that history test normally pays IMT at acquisition. If the property is then resold in a qualifying way within one year, Article 7 allows the assessment to be cancelled on request. This is not an automatic bank refund: the taxpayer needs to make the application and provide evidence of the resale.

One year means the final resale, not the CPCV

The property must be resold within one year of the acquisition. A promissory sale and purchase agreement - the CPCV - is normally a promise to complete later, not the transfer itself. A timetable that reaches only the CPCV before the anniversary can therefore leave the tax benefit exposed.

Work backwards from the legal completion date. Allow time for due diligence, financing, documents and any buyer delay. The resale must also be a genuine onward sale and cannot itself be another acquisition for resale under the same chain.

• Record the exact acquisition date and the last safe completion date
• Do not treat an accepted offer or CPCV as if the resale were complete
• Build a margin for document, bank and registration delays
• Check how the buyer’s stated purpose affects the transaction

Renovation can put the exemption at risk

The most easily missed rule is in Article 11. The exemption is lost if the property is given a different use, and the Code says that completing construction or improvement works - or making other changes capable of altering the taxable property value - can count as a different use.

That does not mean every repair has the same result. It does mean a buy-renovate-resell model should never assume the IMT exemption survives the works. The scope, licences, completion status and possible change in the property’s taxable value should be reviewed before work begins, not after the resale deadline is approaching.

If the conditions fail, IMT and interest can return

If the property is not resold within one year, is put to a different use or is sold again for resale, the exemption ceases. The Code provides for the IMT due from the original acquisition, together with compensatory interest.

Calculate the project’s costs both with and without the exemption. If it is viable only with the exemption, make sure you understand how a lost benefit would affect the investment before committing.

How to request cancellation when IMT was paid first

Article 7 links the request to the procedure for a supervening fact under Article 70(4) of the Tax Procedure Code. That rule uses a 120-day period counted from the point at which the relevant document could be obtained or the fact became known. In a qualifying resale, the prudent approach is to prepare the file immediately after completion.

The local tax office will need to verify the acquisition, the IMT payment, the declared resale activity and the qualifying onward sale. Ask the adviser handling the claim to confirm the competent office, form of submission and exact evidence for the case.

• Acquisition deed or authenticated private document
• IMT assessment and proof of payment
• Portal das Finanças evidence of the resale activity
• Resale deed or authenticated private document
• Land-register evidence and supporting correspondence

Example: the CPCV is signed on time, but the deed is late

Imagine a company completes its purchase on 15 September 2026. On the ordinary reading of the one-year rule, the qualifying onward transfer needs to occur before the corresponding anniversary in September 2027; the precise final date should be confirmed for the file. A CPCV signed in August with completion scheduled for October is not a safe substitute.

If IMT was paid at purchase, the resale is the point at which the cancellation request becomes actionable. If major improvement works are planned, their tax effect must be considered independently of whether the sale can be completed on time.

The best time for tax due diligence is before the offer

Before buying a property for resale, check the purchasing entity, activity registration, previous resales, planned works, intended onward buyer and realistic completion dates. Keep every deed, invoice, tax document and dated decision in one transaction file.

The exemption can be valuable when its conditions are met. A written review before purchase can help avoid discovering after building work or the one-year deadline that a condition was missed.
