From flat tax to real regime in Algeria: a switch prepared a year ahead

In short: Leaving the single flat tax for the real regime is not an adjustment: it is a change of fiscal world, and it runs one way. The option is notified before February 1st of the first application year and is irrevocable; eligibility once acquired under the real regime stands whatever turnover follows. What then changes lists in four lines: tax moves from turnover to profit (corporate or income tax depending on structure), VAT comes back — collected, deductible, filed — accounting becomes full (SCF, financial statements, meeting within six months), and the social fund recomputes its base on the ordinary pre-tax result of the previous year instead of a fraction of turnover. Well prepared, the switch is an act of growth; improvised, a source of penalties. Here is the exact calendar, the four daily shifts and the six months of preparation.

1. 1. Why is moving to the real regime a one-way decision?

Two doors lead to the real regime, and no door leads out of it:

DoorMechanism
The voluntary optionNotified to the tax administration before February 1st of the first application year — and irrevocable
Crossing the thresholdBeyond DZD 8,000,000 (DZD 5,000,000 for the auto-entrepreneur), the switch imposes itself in the year following the crossing

In both cases the consequence is identical: eligibility under the real regime, once acquired, stands whatever turnover follows. An exceptional year therefore definitively closes the flat-tax door, even if activity later falls. It is the reverse of any « test » logic: you do not try the real regime, you choose it knowingly.

2. 2. On what date does one actually switch?

Your situationWhen the real regime applies
IFU taxpayer opting outNotification before February 1st → application from the current year
New taxpayer (incorporation)Option possible as early as the existence declaration « G n°8 »
IFU threshold crossedSwitch from the year following the crossing
Auto-entrepreneur at the ceiling three consecutive yearsTrade-register registration compulsory to carry on, then the regime matching the activity

This calendar explains why preparation starts six months ahead: the option is decided before February 1st, but it plays out in the preceding months — while you can still measure your real margin and install your accounting.

3. 3. What concretely changes day to day after the switch?

AreaUnder the flat regime (IFU / AE)Under the real regime
Tax on profitSingle rate on turnover (0.5 % / 5 % / 12 %)Corporate tax on profit (19 / 23 / 26 %) or progressive income tax for a sole proprietorship
VATInside the flat tax — invoicing all taxes includedCollected on sales, deductible on purchases, filed
AccountingSimplified registers, initialled and countersignedFull SCF accounting, financial statements, meeting within six months
Non-salaried manager's social contributionFlat base: 25 % or 35 % of prior-year turnoverBase = ordinary pre-tax result of year N-1

Two lines deserve rereading. The VAT line changes your displayed prices and your clients: whoever invoiced all-taxes-included becomes an assessee separating out the tax. And the CASNOS line makes the fund run with a one-year lag — your real N-1 result becomes the base of your N contribution, under conditions set by executive decree No. 24-49.

4. 4. The six months of preparation that make the difference

1

Measure your real margin before deciding

The real regime taxes profit; the flat regime taxed turnover. On thin margins the switch relieves; on comfortable margins without deductible charges it weighs. Our article Legal form and turnover sets that comparison.

2

Install SCF accounting before notifying

Chart of accounts, tool or accountant, document habits: full accounting is not learned in January for an option notified February 1st.

3

Prepare apportionment by nature of activity

Article 150 requires apportioning profits across activities — absent credible analytical accounting, the highest rate applies. That discipline is built before the switch, not after.

4

Provision the new deadlines

VAT filings, instalments, tax package: our article on hidden post-incorporation costs shows how a poorly provisioned calendar costs more than the tax itself.
