Nobody has to authorise you to start here. It is exactly that freedom that creates the problem eighteen months later.
What starting means here
The freedom at the outset
You can accept an assignment tomorrow with no prior authorisation, which makes this market very accessible. The trade-off is that nothing reminds you of your obligations until you have triggered them yourself, and that catching up always happens in one go.
Registration and its deadlines
Registration with the tax administration follows a calendar that matches neither your first invoice nor the calendar year. The exact dates and thresholds are checked with the administration or with an accountant, once, at the start of your activity.
What to do in the first thirty days
Seven actions, done once.
Opening a separate bank account.
Checking the registration obligations applicable to your situation.
Noting the filing deadlines in a calendar.
Choosing a simple invoice tracking tool.
Preparing a quote template and an invoice template.
Deciding the percentage to set aside from every payment received.
And making an appointment with an accountant, before needing one.
How to calculate what to set aside
Seven elements to add up, with an accountant.
The estimated tax on profit.
The applicable social contributions.
The possible advance, dealt with above.
Value added tax, if you are liable for it.
A margin for quiet months.
The cost of accounting support.
And equipment renewal, often forgotten.
What to ask an accountant
Six questions, prepared in advance.
Which regime matches my activity and my income.
What percentage to set aside each month.
Which expenses are deductible in my case.
Which deadlines apply to me, and on what dates.
What happens if my income falls sharply.
And from what level another legal form becomes useful.
The tools that are enough
Six tools, not one more.
A spreadsheet to track invoices and payments received.
One folder per year for receipts.
A calendar with the deadlines.
A compliant invoice template.
A separate bank account.
And a backup of all of it, outside your computer.
The tax year does not begin in January
That is the second calendar trap, and it distorts every forecast made in your head. Your income is counted over a period that does not match the calendar year, which means an activity started late in the calendar year can belong to two different periods. Note the applicable dates in a calendar from the first order.
What to keep, and for how long
Seven documents, filed by year.
The invoices issued, in their numbering order.
Purchase receipts, including small amounts.
The business account statements.
Signed contracts and quotes.
Proof of delivery for orders.
The returns filed and their acknowledgements.
And the applicable retention period, to be confirmed with an accountant.
What you can deduct
What really counts
Seven items that genuinely weigh in this kind of activity.
Camera and sound equipment.
The computer and the editing software.
Professional subscriptions.
Travel costs tied to shoots.
A share of the home costs used for work.
Products bought specifically for an assignment.
And professional bank charges.
What does not count
Six expenses often misfiled, to be confirmed with an accountant.
Clothes worn on camera, except in particular cases.
Ordinary meals, outside business travel.
The phone subscription in full.
Mixed purchases, personal and professional.
Gifts and hospitality.
And any purchase with no receipt kept.
What to check every quarter
Six checks, an hour in total.
The amount set aside matches the percentage you decided on.
Every invoice issued has been paid or chased.
The quarter's receipts are filed.
The next quarter's deadlines are noted.
Your prices still cover your costs.
And business expenses all went through the separate account.
Sole trader status or a company
Six criteria for deciding, with an accountant.
The level and regularity of your income.
The administrative and accounting cost of each form.
Protection in case of a dispute.
The way you pay yourself.
Your growth plans over two years.
And what your clients ask for, some preferring to deal with a company.
Social contributions
They follow their own rules, distinct from tax, with their own thresholds and calendar. It is the item beginners most often leave out of their price, and the one that makes a first year look profitable while it is not. The calculation is done with an accountant, with figures in hand.
The signals that should send you to an accountant
Six situations, without waiting for the year end.
Your income doubles from one quarter to the next.
You start invoicing abroad.
You buy significant equipment.
A client asks you for a different legal form.
You are considering hiring, even occasionally.
And you do not understand an amount being demanded.
What genuinely keeps you out of trouble
Seven habits, all free.
Opening a separate account from the first order.
Setting aside a percentage of every payment received.
Keeping receipts as you go, not at the end of the year.
Noting the deadlines in a calendar, once and for all.
Doing a review with an accountant after six months of activity.
Invoicing on the day of delivery, without exception.
And never using the business account for personal spending.
What this framework implies
| Point | What it means | What it requires |
|---|---|---|
| Liability | Personal and unlimited | Insurance worth considering |
| Bookkeeping | Simplified | Records kept up to date |
| Filing | Annual | Deadlines to note |
What decides a change of framework
Rising volume, repeated heavy purchases, or a need to separate personal assets from the activity. None of these is settled afterwards without cost.
What is confirmed with an accountant
The tax registration threshold, the deductible expenses and the form of the records to keep. These rules change and determine real income far more than the advertised rate.
The most frequent mistakes
Six reflexes that cost dearly in the second year.
Assuming tax is paid out of whatever is left at the end of the year.
Ignoring the advance, dealt with above.
Mixing personal and business accounts.
Throwing away receipts for small purchases.
Waiting for the first formal notice before registering.
And setting prices without counting contributions.
One last marker: here, the difficulty is not starting, it is surviving the second year. A separate account, a percentage set aside and a conversation with an accountant remove almost every nasty surprise.
