Tax Audit After a Property Sale in Morocco — how the tax authority challenges your declared price, and how to protect yourself

1. Why the tax authority looks at the price you declare

The price stated in the deed of sale is the tax base for two levies: the TPI (tax on property profits) on the seller's side — 20% of the net gain, with a 3% minimum contribution on the sale price — and registration duties on the buyer's side. An understated price mechanically reduces both. The administration knows this, and compares the declared price with its own estimate of the property's market value at the date of sale.

2. What the seller actually risks

• Look-back period — the administration can go back over the last 4 years. A sale signed today remains challengeable long after the funds have been received (and often reinvested).
• Back taxes — the TPI is recalculated on the administration's revised value, not on the deed price.
• 15% surcharge plus penalties — added on top of the back taxes. On a high-value sale, the bill quickly runs into tens of thousands of dirhams.
• Burden of proof reversed in practice — once the notice is received, it is up to you to demonstrate that your price reflected the market. Without a file built at the time of the sale, that exercise is difficult years later (the buyer may have renovated, the market has moved on…).

3. Red flags that attract the administration's attention

In practice, certain transaction profiles draw particular scrutiny:

• A marked gap with neighbourhood prices — a price per m² noticeably below comparable properties in the same district.
• A declared loss or near-zero gain — selling "without a gain" after many years of ownership, while the local market has risen, raises questions.
• Sales between related parties — intra-family transactions or sales between business partners, where the price can be arranged.
• Atypical properties that are hard to compare — land, riads, assets with development potential: the lack of obvious comparables leaves the administration wider discretion.

Beware of the opposite reflex too: declaring low "because everyone does" is precisely what creates the exposure. Registration duties saved by the buyer are almost always paid back later — through a heavier TPI at resale, or through a reassessment if the administration challenges the price afterwards.

4. The reassessment procedure, step by step

• Step 1 — Reassessment notice: sent by the DGI (registered mail), stating the grounds and the revised value.
• Step 2 — Your written observations within 30 days: with supporting documents, and a counter-appraisal where possible. This is the decisive stage — a solid file here avoids everything that follows.
• Step 3 — The administration's response: it maintains or revises its position. If maintained, a collection notice is issued.
• Step 4 — Appeal before the departmental tax commission, within the following 30 days.
• Step 5 — Further recourse: the national tax appeal commission, then the administrative court if the disagreement persists.

5. Protecting yourself BEFORE the sale — the file that locks in your price

The best defense is built before signing, while the property is still accessible and the market observable:

• An independent valuation report — prepared by a RICS-certified expert before the sale: the property's actual condition (wear, defects, works needed), verified surface area, documented comparables, explicit methodology. It establishes market value at the date that matters — the date of sale.
• Evidence of the acquisition price and works — deeds, invoices, permits: they establish the real net gain and activate the allowable deductions (acquisition costs, documented works, official adjustment coefficients).
• Payment traceability — the full price through banking channels, consistent with the deed.
• Filing on time — the TPI is declared within 30 days of the sale, usually collected by the notary at signing. On the notary's role and why an appraisal before the preliminary agreement pays off, see our dedicated article.

The cost of an appraisal — from 3,500 MAD (excl. VAT) depending on the property — is out of all proportion to a reassessment suffered without a file. It is documentary insurance on a transaction worth hundreds of thousands or millions of dirhams.

6. Defending yourself AFTER the notice — the counter-appraisal

If the notice has already arrived, everything turns on the 30-day written response. The independent counter-appraisal is its cornerstone:

• Demonstrating the real value at the date of sale — the property's condition at the time, photos, surveys, works estimates: everything that justifies a price below neighbourhood averages.
• Challenging the administration's comparables — properties that are not comparable (standing, floor, condition, legal situation), references too distant in time or location.
• Structuring the defense memorandum — a dated, signed report compliant with RICS standards, with explicit methodology, carries far more weight before the appeal commission than a verbal objection.
