Calculation of a company's tax income

Verified 26 May 2023 - Legal and Administrative Information Directorate (Prime Minister), Ministry of Finance

The tax result determines the taxable base to determine the business tax (SI) or income tax (IR) payable by the company. It is obtained from the accounting result on which the non-deductible expenses must be reinstated and then the tax deductions deducted.

Step-by-step approach

The accounting result shall be determined at the end of each accounting year when the annual accounts are drawn up.

It matches the duty-free turnover (or products) realized during the year less charges linked to the company's activity. It corresponds to the formula: Products - Expenses

It is indicated in the profit and loss account.

When the accounting result is positive, the company makes a profit. When it is negative, it is a deficit.

Where the company is subject to income tax (IR) and carries on an activity of a kind commercial, industrial or handcrafted, income from this activity is taxed in the category of BIC: titleContent. If the activity is liberal, income is taxed in the category of NBC: titleContent.

The expenses must then be added to the resulting accounting result non-deductible from a tax point of view, we are talking about fiscal reintegration.

these include:

The 3e step consists of subtract of the accounting result on tax deductions (or extra-accounting). These are revenue recorded in the accounts but not taxable for tax purposes or previously taxed (recapture of provision reinstated in a previous fiscal year).

These include:

The tax result is therefore obtained by the following formula:

Tax result = accounting income + tax reinstatement - tax deductions

It must be indicated in the tax book filed at the time of the income statement filed by the company subject to business tax (IS) or income tax in the Industrial and Commercial Benefits (BIC) or non-commercial profits (NBC).
