File your tax return yourself or use an accountant?
The choice depends on the work to be done: entering a file you already understand, getting help from software or having a tax situation properly assessed. MyGuichet is an official channel; software and a firm offer different services. Compare the scope rather than a price on its own.

When doing it yourself may be enough
If you know your situation, have consistent certificates and understand the sections to complete, filing on your own may be appropriate. The official assistant can guide data entry within its scope, but a completeness check is still needed.
An automatic import saves re-entering data; it does not confirm your tax residence, the treatment of a foreign property or whether an option for the couple is worthwhile. Check what is included in the tool you use.
When to have your file reviewed
Foreign income, several categories of income, a change of residence or a disputed tax assessment notice often justify additional analysis. The value of the engagement then lies in assessing the data correctly and explaining the result, not simply in filling in the PDF.
Fictitious example: the salaries are imported correctly, but the spouse’s income needed to determine the rate is missing. The file may look finished without the return actually being complete.
Questions to ask before you buy
- Who checks the documents and the options?
- Who signs and who submits? Is the mandate included?
- Does the price cover the household, the schedules and foreign income?
- What happens once the tax assessment notice is received?
- How are documents protected, and can they be exported?

Depending on your situation, the firm also handles tax, VAT and payroll, the regularisation of late tax filings and assistance during a tax audit. Fees are listed in the firm’s fee grid.
Official sources and scope
The rules apply to the year and profile concerned. Examples flagged as fictitious explain a method; they are not an individual validation. The documents and options of your file are covered by a separate engagement.
