Moroccan Expats Face Hidden Tax on Dream Homes: 300m² Threshold Triggers Costly Declarations

However, beyond a certain size threshold, a specific tax burden applies: the social solidarity contribution on personal housing constructions. And many are unaware of it until the time of payment.

The key threshold of 300 m²: beyond that, a tax applies

According to the 2025 MRE Tax Guide, any construction of a main residence is exempt from this contribution up to 300 m² of built-up area. On the other hand, as soon as the area exceeds this threshold, even by one square meter, the entire area becomes taxable.

The scale is modest, but mandatory:

• Up to 300 m² Exempt
• Between 301 m² and 400 m² 60 dirhams
• Between 401 m² and 500 m² 100 dirhams
• Beyond 500 m² 150 dirhams

Even if the amounts seem low, the issue is less financial than declarative: any house exceeding 300 m² must be the subject of a rigorous administrative process.

Mandatory declaration, every year

MREs who build a dwelling exceeding 300 m² must file an annual declaration of the construction cost, from the start of the work until the obtaining of the occupancy permit. This declaration is made electronically and must be accompanied by a detailed statement of expenses: suppliers, materials, amounts, method of payment, etc.

In the first year, a certificate from an architect or a turnkey contract is required. In subsequent years, the cumulative work done must be indicated. Finally, a specific declaration of the social contribution must be filed within 90 days of the issuance of the occupancy permit.

Penalties in case of oversight

Failure to declare or ignore this contribution can result in:

• Late payment penalties,
• A tax notice,
• Administrative blockages, particularly in the event of resale or regularization of the property.

It should be noted that these obligations also apply to houses built after 2019, as long as a building permit has been issued.

This contribution, little known to the general public, is not intended to discourage MREs from building, but to regulate the declaration of large-sized properties. In fact, it is mainly the non-compliance with administrative procedures that poses a problem.

Many MREs build in the country thinking they are exempt from any obligation, especially if they do not rent out the property. However, the law is clear: beyond 300 m², the declarative obligation applies, regardless of the use of the dwelling.
