Filing VAT under the simplified regime

Two conditions rather than one, including a 15 000 € VAT threshold that turnover does not reveal; two instalments computed on the year before, adjustable beyond a 10 % difference; a single return in May, and two credit refunds with different minimums. Three modules on a plumber with 168 000 € of turnover. All the prose is free to read; only the quizzes are sold.

2026 rules — verified on September 11, 2026

Figures are tied to dated, sourced tax constants. A module whose rules have changed is flagged for review, and is unpublished automatically beyond 90 days.

By the end of this course, you can…

These outcomes are the modules' own: the promise cannot say anything the course does not teach.

  • Place the simplified regime between the VAT exemption and the normal regime.
  • Remember the double condition: turnover under a ceiling and annual VAT below 15 000 €.
  • Understand what takes a business out of the regime, and the option for the normal regime or the mini-normal.
  • Spot the activities excluded from the simplified regime at start-up.
  • Compute the two instalments: 55 % in July, 40 % in December, on the previous year's VAT.
  • Adjust or suspend an instalment when the expected VAT departs by more than 10 %.
  • Identify the exemption from instalments below 1 000 € of annual VAT.
  • Handle the first year of activity and a financial year that does not follow the calendar year.
  • File the annual 3517-S CA12 return on the right date, calendar year or off-calendar financial year.
  • Settle the balance between VAT due and instalments paid.
  • Claim a refund of a VAT credit, annual or half-yearly, with its minimums.
  • Measure what a late filing and a change of regime during the year cost.
