The INPS exemption band, the paperwork and the move to a VAT number

Paolo is a graphic designer. In 2026 he was paid 3,000 € in March by an agency and 2,800 € in October by a publisher, each time on a receipt. In March nobody raised social security. In October they did: the second job pushed him past the INPS exemption band, and from that moment his client has a new obligation too.

A band that concerns contributions only

The first module pulled apart two questions that are often blurred: whether you need a VAT number and whether you owe contributions. The first turns on habitual activity. The second, for those who stay occasional, turns on a euro threshold set by social security rules and described on the INPS page.

The band is counted over the year and across all clients together. There is no separate band for each client. Someone working for three different companies adds up the fees from all three and compares the total with 5,000 euros. The year's total decides, not any single job.

Crossing the band does not work backwards. Contributions apply to the amount above the threshold, not to the whole year's earnings. Someone reaching 5,800 euros pays contributions on 800 euros, and the first 5,000 stay exempt even though they were received earlier.

The count restarts every year. Having exceeded the band in 2026 does not carry over into 2027: the first 5,000 euros of occasional fees in the new year are exempt again. Enrolment in the Gestione separata, however, stays in place and does not have to be repeated when the band is crossed once more.

Timing matters as well. The band is measured on fees paid out by the client, and the contribution is due by the 16th of the month after payment. Work done in December but paid in January therefore counts towards the new year, not the one in which it was carried out.

The amount contributions are worked out on

The INPS page recalls that, for tax, occasional income is receipts minus the costs of earning them. For contributions it states its own rule: the base is the gross fee paid, less any expenses charged to the client and shown on the fee note the worker gives the client.

The difference from the tax rule is subtle but real. For IRPEF every related cost counts, including those the worker bore alone. For INPS only expenses charged on to the client and shown on the document count. If you want a reimbursement kept out of the base, list it separately on the receipt.

The Gestione separata contribution rate is not given in this course. INPS updates it every year in a circular, together with the ceiling and floor, and that is where it should be read for the year concerned. Here you learn to tell when a contribution is owed and on what base.

Who pays, and in what shares

Occasional self-employed workers follow the same rules as coordinated and continuous collaborators: enrolment, split of the contribution, payment and reporting. INPS says so in plain terms, pointing to the well-tested framework already used for collaboration contracts.

The split does not mean each party pays its own part. The client pays the entire contribution and deducts the worker's share from the fee. On a paid receipt the worker therefore sees two separate deductions: the 20 % tax withholding and their share of the social security contribution.

To get the calculation right, the client asks the worker for a statement on their contribution position, for instance whether they draw a pension or are covered by another compulsory scheme. Answering accurately avoids contributions being paid at the wrong level and then having to be corrected.

Several clients in the same year

A client cannot know what the worker has earned elsewhere. That is why the duty to report crossing the band falls on the worker: the INPS page asks workers to tell their clients promptly once the exemption threshold has been exceeded.

In practice, keep a simple log of occasional fees with the date and amount of each receipt. Before each new job, check the running total: if the coming fee will take you past 5,000 euros, tell the client before payment and state the portion above the band.

When the band is crossed through several fees from different clients in the same month, each client works out its contribution proportionally. Each share follows the ratio between that client's fee and the total paid out in the month. No single client carries the excess alone.

Joining the Gestione separata

Once past the band, the worker must enrol in the Gestione separata. Enrolment is a one-time step: anyone already registered, for example from an earlier collaboration contract, does not do it again. The INPS page makes this point precisely to prevent duplicate records.

The contributions paid are not lost. They build the worker's pension record in the Gestione separata, under the general crediting rules INPS refers to. For people doing occasional jobs while studying, they are often the first contributions of their working life.

The client's certificate

A client that withheld tax must certify it. According to the Agency's page, the certificate states the total sums paid, the tax withheld, the credits applied and the social security contributions. It is the document the worker will use when filing the return.

Check it as soon as it arrives. The total paid must match the receipts you issued, and your share of contributions must appear separately from the tax withheld. A mistake spotted in spring is fixed with the client; one found after filing costs far more to put right.

Signs that occasional work is coming to an end

The fee log tells you something else that is often overlooked: how frequent the work is. An entry now and then fits occasional work. Entries coming in every month, with the same names, describe an activity that is taking shape, even if the total remains modest.

Other signals come from outside. One client wants a yearly contract, another asks for an electronic invoice, a third wants your VAT number to set you up as a supplier. None of these settles the matter alone, but each is the right moment to redo the first module's assessment honestly.

Putting off the decision does not pay. The duty arises on the day the activity became habitual, not on the day you admit it. Registering a few weeks early costs one form; registering a year late means rebuilding invoices, VAT and returns after the fact.

The day a VAT number becomes necessary

Exceeding the exemption band does not oblige you to register for VAT: only your contribution position changes. A VAT number becomes compulsory when the activity turns habitual, whatever amount has been reached. The two thresholds can arrive at different times, or one without the other.

Professionals, and anyone whose activity needs no Companies Register entry, use form AA9/12. It is due within 30 days of the start date and can be sent by PEC, handed in at an office, mailed by recorded delivery or submitted online from the Agency's reserved area. The course on opening a VAT number goes through it box by box.

After registration: what changes

With a VAT number the worker stops issuing receipts and sends electronic invoices instead. The fee is no longer miscellaneous income but self-employment income, and the return moves to Redditi Persone fisiche. The contribution regime also changes in nature compared with occasional work.

A professional enrolled in the Gestione separata may pass on to the client a 4 % contribution surcharge. The Agency's page states that this amount forms part of the base on which a client acting as withholding agent computes the withholding. Occasional work has no such surcharge: the client's share is a contribution, not a line on an invoice.

Many people opening a VAT number look at the flat-rate scheme, the regime forfettario. It applies automatically to those who meet its conditions, replacing IRPEF with a substitute tax and simplifying VAT. The eligibility calculator lets you check in a few minutes whether you are within its limits and clear of its exclusions.

A year of occasional jobs, month by month

Holding the tax and contribution rules together takes a simple method. The most reliable is a sheet with one line per receipt: date, client, gross fee, expenses charged, tax withheld, any contribution share and the running total for the year. It takes a few minutes per job.

The running total is the column INPS cares about. As it nears 5,000 euros, the sheet shows in advance which job will take you over the band. That is the moment to write to the client, prepare enrolment in the Gestione separata and expect a smaller net payment.

The withholding and expense columns serve the following year's return. The withholding total must match the certificates you receive, and documented costs reduce miscellaneous income. A tidy sheet turns the 730 into half an hour's work.

Workers who already have pension cover

Many occasional workers already have another record: they are employees, pensioners or members of a professional fund. That is exactly why the client asks for a statement on their contribution position. Drawing a pension or belonging to another compulsory scheme affects the contribution due.

How it changes is set by INPS in its yearly circular on Gestione separata rates, which distinguishes covered from uncovered workers. This course does not quote those rates: the point is that the statement to the client is not a formality, and it must be updated if your situation changes during the year.

An employee doing occasional work follows the same logic: yearly band, notice to clients, enrolment in the Gestione separata above the threshold. Already paying contributions as an employee does not remove the duty to enrol, though it may affect the level of the contribution.
