In brief: Form 9421 is the annual wages and salaries return that every employer in Morocco must file before 1 March via the DGI’s SIMPL-IR platform. It lists all employees paid during the year with their gross salary, deductions, and income tax withheld.
The wages and salaries tax return (known as Form 9421) is an annual return to be filed by employers in Morocco before 1 March. Article 79 of the General Tax Code stipulates that employers must submit an annual salary return by the end of February at the latest. This return is commonly called Form 9421 (or Statement 9421).
Form 9421 provides a comprehensive list of all employees that a company has paid during the previous fiscal year. It serves as a critical control tool for the General Tax Directorate (DGI), enabling the tax authorities to cross-reference income tax (IR) amounts withheld at source by employers against individual employee tax returns.
What Is Form 9421?
Form 9421 is the official document through which every employer in Morocco summarises all remuneration paid to its employees during the preceding calendar year. For each employee, it details gross salary, social and tax deductions, net taxable income, and the amount of income tax withheld at source.
This document plays a central role in the Moroccan tax system. It allows the tax administration to verify that the employer has correctly calculated and remitted the salary income tax for each employee. Form 9421 is therefore the logical extension of the monthly IR payment slips that the employer files each month.
Legal Basis for Form 9421
The obligation to file Form 9421 stems from Article 79 of the General Tax Code (CGI). This article requires every employer domiciled or established in Morocco to provide the tax administration with an annual summary statement of wages and salaries paid.
The article specifies that the return must be submitted before 1 March of the year following the one in which the salaries were paid. In other words, for salaries paid during the year 2025, Form 9421 must be filed no later than 28 February 2026.
Who Must File Form 9421?
Every employer who pays wages, salaries, allowances, or emoluments subject to income tax is required to file Form 9421. This applies to commercial companies, associations, public administrations, self-employed professionals with staff, and private household employers alike.
The obligation applies regardless of the number of employees. Even an employer with only one employee is required to file this return. Furthermore, Form 9421 must be prepared even if no income tax has been withheld, for example when the salary paid is below the tax threshold.
Filing Deadline for Form 9421
The statutory deadline for filing Form 9421 is before 1 March of each year. This deadline is mandatory, and failure to meet it exposes the employer to penalties.
It is strongly recommended not to wait until the last days of February to prepare and file the return. Preparing in advance, from January onwards, allows time to verify data consistency and correct any errors before submission.
Sections of the Annual Wages and Salaries Tax Return (Form 9421)
For each recipient of wage income that the employer has paid in the previous year, the following information must be indicated on Form 9421:
- Surname, first name, and address of the employee;
- National identity card (CIN) number, residence permit for foreign employees, and National Social Security Fund (CNSS) registration number;
- For each employee, the following detailed amounts:
- Gross amount of wages, salaries, and emoluments;
- Allowances paid in cash or in kind during the year;
- Allowances paid as employment and service expenses, representation expenses, travel expenses, mission expenses, and other professional expenses;
- Gross taxable income;
- Deductions made for retirement pension, CNSS, and social welfare organisations;
- Professional expenses;
- Instalments deducted for principal and interest on loans taken out for the purchase of social housing;
- Number of deductions for family dependants;
- Net taxable income amount;
- Amount of income tax withheld;
- Period to which the payment applies.
How to Complete Form 9421 Section by Section
Completing Form 9421 follows a logical order. The header of the form contains employer identification information: company name, tax identification number (IF), ICE number, and registered office address.
The main body of the form is a table in which each row corresponds to an employee. For each employee, the successive columns are filled in starting from total gross salary, then deducting social contributions (CNSS, AMO, supplementary pension), flat-rate professional expenses, and any deductions for family dependants. This leads to the net taxable income, from which the withheld income tax is calculated using the applicable progressive tax schedule.
Occasional Employees to Declare in Form 9421
In addition to permanent employees, Form 9421 must be supplemented with an annex listing occasional wages and allowances.
When a company employs workers who are not part of its permanent staff, it must apply a 30% withholding for income tax purposes. Annually, the list of these occasional employees must be appended to the annual wages and salaries tax return.
This list includes:
- Surnames, first names, address, and profession of each beneficiary;
- Gross amount of sums paid and deductions made.
Specific Sectors
The legal obligation regarding the wages and salaries return makes no distinction based on the nature of the business activity. The return must normally list, by name, all of the company’s employees, regardless of the amount of remuneration received by each of them.
However, as a simplification measure, the administration authorises employers not to individually list non-permanent employees whose gross annual remuneration is equal to or less than the minimum wage (SMIG or SMAG). This simplification only applies to the following sectors:
- The agricultural sector;
- Construction, public works, and related industries;
- Cereal traders;
- Canning manufacturers;
- Fruit and vegetable packing station operators;
- The coastal fishing sector.
These employers will indicate in the return, under the heading “non-permanent workers”, the total amount of cash wages and benefits in kind allocated to said workers, specifying their headcount by employment period.
Online Filing via SIMPL-IR
Form 9421 must be filed electronically through the DGI’s SIMPL-IR platform. The employer must prepare an XML file that complies with the format required by the tax administration. This file is then uploaded directly to the SIMPL portal.
The e-filing procedure involves several steps. The employer logs into their account on the DGI website, navigates to the SIMPL-IR section, selects the wages and salaries return, and then imports the XML file. Once validated, an acknowledgement of receipt is generated, confirming that the return has been filed.
It is possible to file a corrective return via SIMPL within 60 days of the initial filing, without penalty.
Relationship with Monthly IR Payment Slips
Form 9421 is directly linked to the monthly IR payment slips (bordereaux de versement). Each month, the employer withholds income tax at source on salaries paid and remits it to the Treasury through a payment slip. Form 9421 serves as the annual summary of these monthly payments.
The total IR declared in Form 9421 must match exactly the sum of amounts paid monthly through the payment slips. Any discrepancy between these two figures can trigger a tax audit. It is therefore essential to maintain rigorous tracking of monthly payments throughout the year.
Penalties for Late Filing or Errors
Failure to meet the filing deadline for Form 9421 exposes the employer to financial penalties. The penalty for late filing is a fine of 500 dirhams per employee, with a minimum of 2,000 dirhams. In the case of an incomplete return or one containing inaccuracies, additional surcharges may apply.
Furthermore, failure to file can result in ex officio taxation by the tax administration, with late payment surcharges of 5%, 10%, or 15% depending on the length of the delay, plus late payment interest of 0.50% per month.
Common Mistakes to Avoid
Several errors frequently occur in the preparation of Form 9421:
- Inconsistency between monthly amounts and the annual summary: the total IR declared must match the sum of monthly payments.
- Omitting employees: all employees who received remuneration must appear on the return, including paid interns and employees who left the company during the year.
- Errors in identification numbers: an incorrect CIN or CNSS number can cause the XML file to be rejected.
- Incorrect calculation of deductions: flat-rate professional expenses are capped at 35,000 dirhams per year at the standard rate of 20%.
- Failure to declare benefits in kind: benefits such as company housing, company car, or bonuses must be included in gross taxable income.
Reconciliation with Annual Accounts
Form 9421 must be consistent with the company’s annual financial statements. The total gross salaries declared must correspond to the personnel costs recorded in the income statement (accounts 6171 and following under the Moroccan chart of accounts).
The chartered accountant systematically performs a reconciliation between the total salaries shown in Form 9421, the monthly IR payment slips, CNSS returns, and accounting entries. This reconciliation helps detect and correct any discrepancies before the return is filed.
The Role of the Chartered Accountant in Preparing Form 9421
Preparing Form 9421 requires technical expertise in the tax rules applicable to wage income. The chartered accountant intervenes at multiple levels: verifying payslip compliance, calculating applicable deductions and exemptions, generating a compliant XML file, and submitting the e-filing via SIMPL.
Engaging a chartered accounting firm such as Upsilon Consulting secures the process and prevents errors that could lead to penalties. Our team handles the complete preparation of Form 9421, from accounting reconciliation through to electronic filing.
