Portugal opens CIA rental-investment applications

Portugal’s housing agency has launched an online platform for rental-investment contracts, known as CIA. Projects that meet the rules can get tax breaks for 10 to 25 years. In return, investors must follow rent limits, keep homes in rental use and meet reporting rules.

IHRU announced the Investir-Arrendar platform on 14 October 2026. The CIA legal regime took effect on 1 September, and detailed application rules followed on 1 October. Investors can use the site to apply, track their case and manage their contract.

A CIA is a housing-investment contract with the Portuguese state. It does not itself grant a residence permit or citizenship. Anyone planning both a property investment and a move needs to check the two processes separately.

Portugal CIA contracts at a glance

• Projects: buying, building or renovating homes for residential rental.
• Housing share: at least 70% of the buildings’ total construction area must be used for qualifying residential rental.
• Rent limit: the legal moderate-rent ceiling applies.
• Length: normally 10 to 25 years.
• Where to apply: IHRU’s online platform, reached through the Portal da Habitação.
• Experience: more than three years in a qualifying property field, with rules allowing certain owners, linked companies or managers to meet this test.

Who can apply?

A person, company or other entity may apply. The investor must show that it can manage the project. It must keep proper accounts and pay tax and social security on time. Its taxable profit cannot be set using indirect assessment methods.

The experience test covers property investment, development, property management or residential-rental management. It can be met through the investor’s own record or through:

• a person or entity that holds at least 25% of its capital or voting rights;
• an entity in which the investor holds at least 25%; or
• members of its management bodies.

Holdings through another company can count too. Gather proof that you meet the test before you apply.

Which properties and rents qualify?

A CIA may cover existing homes bought for rent, land or buildings bought for construction, or property bought for renovation. At least 70% of the total construction area covered by the contract must serve residential rental. This can include a lease to a firm that rents the homes to tenants. Other space must have a use that fits with housing.

The monthly rent cannot exceed the moderate-rent limit in the law. Its starting formula is 2.5 times the monthly minimum wage set for 2026. The government may change the limit by legal order. Check the amount that applies to the project before setting rents.

The test uses the total rent and some extra charges. These can include costs for equipment fixed to the home and services that add value. Putting these charges in a separate deal may not keep them outside the cap.

A CIA that also uses the simplified affordable-rental scheme, or RSAA, must meet that scheme’s extra rules and local rent limits too.

What tax benefits can a CIA offer?

The final contract states which benefits apply and on what terms. The law allows:

• an exemption from property transfer tax, known as IMT, on qualifying purchases;
• a stamp-duty exemption on those transfers;
• an exemption from annual municipal property tax, or IMI, for up to eight years, counting from the purchase year;
• a 50% IMI reduction for the remaining contract term, within the legal limit;
• the reduced VAT rate on qualifying construction or renovation contracts;
• an exemption from the additional property tax, AIMI, during the CIA;
• a refund of 50% of the VAT-equivalent cost of qualifying architecture, engineering, design and study services, excluding urbanisation works projects and studies; and
• a 50% reduction in the relevant stamp-duty rate for qualifying alternative investment funds, based on their eligible rental assets.

The local council must propose the IMT and IMI tax breaks. The municipal assembly must then approve them. Do not assume every tax break will apply to your home.

How long must the homes remain rented?

The CIA sets a deadline to put the homes into rental use. For construction or renovation projects, this cannot normally exceed five years from signature. For existing properties bought for rental, the limit is one year from signature.

IHRU may extend the construction or renovation deadline where there is a justified obstacle. During each full year of the CIA, the homes must normally be covered by qualifying rental contracts for at least eight months. The law allows for a justified obstacle to this requirement too.

Investors must list the homes and give officials the records they need for checks. They must also report changes that affect the project. As a rule, you cannot sell or transfer a home on its own. Your role under the CIA must pass to the new holder at the same time, under the transfer rules.

A breach can end the contract. You may have to repay tax breaks, plus interest. The amount to repay depends on when the breach happens. Take advice before changing ownership, rental use or the project’s structure.

How does the application process work?

Apply through the IHRU platform. Give details of the investor and anyone acting for them. Show the right to use the property and explain the project. Include the site, property records, planned works, floor area and homes for rent.

State how long you want the contract to last. Supply proof that tax and social-security payments are up to date, plus the required declaration. The usual term is 10 to 25 years. A CIA linked to a qualifying public-private partnership follows that partnership’s term.

If the form does not meet the rules, IHRU has 20 days from filing to ask you to fix it. For a complete filing, the rules give IHRU 20 days to send a draft contract. For a corrected filing, the period is 10 days. The government must still approve it before the parties sign. These steps are not a promise that the whole process will finish within 20 days.

What should investors check first?

1. Work out the rental income. Check that the project works at the permitted rent after costs and empty periods.
2. Check the local tax decision. Confirm which benefits the municipality has approved.
3. Prepare the experience evidence. Show clearly who meets the test and how they are linked to the applicant.
4. Plan for the full term. Include rental-use, reporting and transfer limits in the business plan.
5. Review the final contract. Ask Portuguese legal and tax advisers to check the property-specific terms before signing.
