When registration stops being optional, what changes on your invoices, and why some creators register before they have to.
The small supplier threshold
Four points to know.
Below the threshold, registration stays optional and the tax is not charged.
Above it, registration becomes compulsory and charging starts, with a precise deadline to respect.
The calculation is made over the rolling period, dealt with above.
And the exact value of the threshold as well as the calculation rules are checked with the competent administration or with an accountant, because they change and vary with the situation.
What changes on the invoice
Five elements appear on the day of registration.
Your registration number, which becomes compulsory on every invoice.
The tax, calculated on the amount before tax and stated separately.
The applicable rate, which depends on the client, a point dealt with below.
The total to be paid, distinct from your income.
And the mention of the applicable regime when the service is not taxable.
One accounting consequence: from that day, your turnover and your receipts no longer coincide. The amount arriving in the account contains a share that is not yours.
Why some register early
Four legitimate reasons to register before the obligation.
Recovering the tax paid on professional purchases, notably during a large initial equipment phase.
Credibility with companies, for whom a registered supplier is a usual supplier.
The absence of a break: crossing the threshold mid-year forces you to change your invoices and sometimes your rates.
And administrative simplicity, one single rule being better than two different periods in the same year.
The trade-off: periodic returns to produce, even with no activity, and slightly stricter bookkeeping.
The rate depends on the client's province
Four practical rules.
The applicable rate is determined by where the client is, not by where you are.
The same month can therefore carry several different rates on neighbouring invoices.
A client outside the country falls under a particular treatment, to be checked according to the nature of the service.
And the client's location information has to be requested and kept, because it justifies the rate applied.
One simple habit: note the client's province in your invoicing table, next to the amount. It is the data always missing at declaration time.
What decides whether to charge tax
| Situation | Tax applies | To verify |
|---|---|---|
| A client in the same province | In principle yes | The applicable rate |
| A client in another province | Per place-of-supply rules | Their real address |
| A client outside the country | Often zero-rated | Proof of their establishment |
What is set up from registration
A separate account for collected tax, an invoice showing the registration number, and a filing calendar noted in advance.
What is confirmed with an accountant
The mandatory registration threshold, the regime most favourable to your volume and the treatment of foreign clients. These three vary and cannot be deduced from an article.
The practical version
Six habits, to put in place from the first month.
A monthly table with the rolling total of the last twelve months.
The client's province or country noted on each line.
A separate account into which the tax collected is transferred on receipt.
Compliant invoices, with the registration number and the tax stated separately.
Receipts for professional purchases kept, for recovery.
And a yearly appointment with an accountant, plus a check as soon as the threshold approaches.
One last marker: in this area the risk is not paying the tax, it is having collected it without knowing. An invoice issued without the tax when the obligation had already started is still owed, and nobody will pay it back for you.
