- Auto-entrepreneurs registered with ANAE, on the annual flat contribution set by law 22-23.
- Registration must be filed within 10 days of the effective start of the activity.
- Registration opens the Chifa card, sickness benefits and pension rights.
The registration file
The file is submitted to the agency of the wilaya where the activity is carried out. Documents required:
- The original registration form, signed.

- Existence certificate issued by the tax administration.
- Craftsman professional card or agricultural certificate depending on the activity.

Annual declaration and payment
The contribution is annual. The calendar and the payment channels are the same in every wilaya.
- Contribution due on 1 January, payable before 30 June. 30 September for farmers.
- Quarterly or half-yearly instalments are possible on request at the agency.
- Payment online on Damancom with a CIB or Edahabia card, at the agency counter, by bank transfer or by CCP deposit.
- Late payment: a penalty of 11 % of the annual amount, then 1 % for each additional month.
- No declaration within the deadline: the fund may set the contribution provisionally on the previous year base increased by 5 %, an increase definitively acquired by the fund.
What you will pay in 2026
The amount does not depend on the wilaya. It depends on your tax regime and your declared income, under article 14 of décret exécutif 15-289 as rewritten by décret exécutif 26-257 of 15 July 2026.
- Overall rate of 15 %, split into 7.5 % pension and 7.5 % social insurance.
- Annual base at least equal to the annual SNMG, i.e. 288,000 DZD with the SNMG at 24,000 DZD a month.
- Base capped at 20 times the annual SNMG, i.e. 5,760,000 DZD.
- Annual contribution between 43,200 DZD and 864,000 DZD. Both bounds are derived from the SNMG in force, neither appears in the decree, and both follow the next revaluation.
- ANAE auto-entrepreneur: a flat 24,000 DZD a year, with the option to take the ordinary calculation at 15 % of declared income.
- From the third year of activity an extra floor applies, equal to the average contribution for the same activity in the same wilaya the previous year. It is set by ministerial arrêté and the arrêtés are unpublished so far, so no amount can be quoted.
