Why does the final result differ from one year to the next?

The final result of the tax return may differ from one year to the next due to changes in income, tax deductions and credits, tax laws and possible errors in the return. It is therefore important to calculate your tax correctly each year to avoid any problems with the tax authorities.

The final result of the tax return may differ from one year to the next for several reasons:

Changes in income: Income can vary from one year to the next depending on various factors such as salary increases, bonuses, investment income, etc. These variations in income can have an impact on the amount of tax you have to pay.

Changes in tax deductions and credits: The tax deductions and credits to which a person is entitled may change from one year to the next depending on their personal situation and the tax legislation in force. For example, changes in deductible medical expenses, child tax credits, etc., can affect the amount of tax you have to pay.

Changes to tax laws: Tax laws can change every year, which can have an impact on the calculation of tax you have to pay. These changes can affect tax rates, income thresholds, tax deductions and credits, etc.

Errors in the tax return: Errors in the tax return can also lead to variations in the final result. It is important to carefully check all the information provided on the tax return to ensure that it is correct.

Changes in family situation: If a person gets married, divorced, has children or any other significant change in their family situation, this can have an impact on the amount of tax to be paid. For example, the number of dependents, family allowances and tax credits may be affected by these changes.

Changes to assets and investments: If a person makes capital gains, sells property, invests in financial products or any other type of investment, this may have an impact on the amount of tax to be paid because of the specific rules for taxing this income.

Variations in deductible expenses: Deductible expenses can differ from one year to the next depending on the expenses incurred by a person in connection with their professional activity, health, training, etc. Factors such as transport costs, childcare costs, insurance deductions can influence the amount of tax to be paid.

Change of tax status: If a person's tax status changes from one year to the next (for example, from employee to self-employed), this can have significant tax consequences, particularly in terms of the tax rates, deductions, and tax credits applicable.
