Contributions on the minimum
A fixed annual sum, due in full even with zero income or a loss. It is paid in four equal quarterly instalments, regardless of how the business is doing.

INPS contributions for artisans and traders
Unlike the Gestione Separata, here part of the contribution is due regardless, even with zero turnover. It is the item that most often catches out people starting a business: understanding how it works before you open changes your decisions.
01 · Who must enrol
Who enrols in the INPS fund for artisans and traders
Enrolment applies to anyone running a business with personal involvement in the work, meaning people who work in their own business, not those who simply invest in it. INPS is the Italian social security institute.
| Who | Fund | Note |
|---|---|---|
| Sole trader in a craft trade | Artisans | Registration in the register of craft businesses |
| Sole trader in commerce | Traders | Covers retail and wholesale, bars and restaurants, many services |
| Working partner in a partnership | Depending on the activity | Every partner who works in the business enrols |
| Working shareholder in a commercial SRL (limited company) | Traders | If they personally take part in the work of the business |
| Family helper | Depending on the activity | In a family business, if the contribution is habitual and predominant |
Many professionals think they fall under this fund when in fact they belong to the Gestione Separata (the INPS fund for freelance professionals). The dividing line is between business activity and professional self-employment, and it must be checked when you open, not afterwards.
02 · Fixed and excess
The two parts of the contribution
The contribution has two parts that follow different logic, and mixing them up is the source of almost every forecasting error.
Contributions on the excess
A percentage of the part of income above the minimum. It is paid together with income taxes, as a balance and advance payments, so only after the year has closed.
Ceiling
Above a certain level of income the contribution stops rising. It affects few people, but for those few it makes a big difference.
The practical consequence: in your first quarter of business you are already paying fixed contributions, even though you have not yet been paid anything. It is the single element most often overlooked when opening.
03 · The calendar
When you pay
The two parts follow separate calendars, and in some months they overlap.
Four fixed instalments
Contributions on the minimum are paid in four quarterly instalments with the F24 (the Italian tax payment form), on fixed dates during the year.
Balance for the closed year
By the tax return deadline you pay the excess on the income actually earned the previous year.
First advance payment
By the same deadline you pay an advance on the excess expected for the current year.
Second advance payment
In the autumn the advance is completed. This is the month when the heaviest burden falls.
The difficult month
At the mid-year deadline several items fall due at the same time.
- Balance of the previous year's excess
- First advance on the current year's excess
- Quarterly instalment of the fixed contributions
- Balance and advance on income taxes
04 · Concessions
Possible reductions and concessions
There are a few ways to reduce the burden. They are not automatic: almost all of them require an application by a precise deadline, and anyone who applies late loses the concession for the whole year.
- Reduction for taxpayers under the flat-rate scheme (regime forfettario): a percentage cut on fixed and excess contributions, with an online application by the annual deadline. It also reduces pension credit in proportion.
- Reduction for pensioners who keep working, above a certain age.
- Reduction for family helpers below a certain age.
- Concessionary regimes for new businesses, when provided for by the rules in force that year.
The reduction for the flat-rate scheme needs weighing up, not taking for granted: it lowers the contribution but reduces the months credited to your pension by the same proportion. For someone with a long career behind them it may pay off; for someone still building their pension position, often not.
05 · The most debated case
The SRL shareholder who works in the business
This is the situation that generates the most disputes. A shareholder in an SRL operating in a commercial sector who personally works in the business must enrol, even if they receive profits rather than a salary.
The test is one of substance, not form: what counts is whether the shareholder habitually works in the business, not how they are paid. Being a director only, without taking part in the work of the business, follows different rules.
- Someone who is only a director, without working in the business, falls under the Gestione Separata on the fee received.
- Someone who works in the business and is also a director may have both obligations, on different bases.
- The contribution base for a working shareholder is the share of business income attributed to them, not the profit distributed.
- Dividends as such are not a contribution base: what counts is the company's income attributed to the shareholder on a look-through basis for contribution purposes.
This is one of the assessments to make before forming the company, not afterwards. The company structure that minimises taxes is not always the one that minimises contributions, and the overall cost can only be read by looking at the two together.
06 · When you close
Closing the business and your INPS contribution position
Closing the partita IVA (Italian VAT number) does not automatically close your INPS position. They are two separate notifications, and the second is forgotten with some regularity.
- Deregistration from the pension fund must be requested expressly, with the date the business actually ceased.
- Fixed contributions accrue up to the date of deregistration, pro rata by month.
- The balance and excess on the last period of activity remain due, and are settled with the following year's tax return.
- A position left open keeps generating fixed contributions and, years later, INPS payment notices (avvisi di addebito).
Frequently asked
The questions that keep coming up
If I have not been paid anything, do I still have to pay?
Yes, contributions on the minimum are due simply because you are enrolled, regardless of the income you earn.
This is the fundamental difference from the Gestione Separata, where no income means no contribution. Anyone opening a commercial business must budget for this fixed outgoing from the very first quarter.
Is it worth applying for the flat-rate scheme reduction?
It depends on your contribution history. The reduction lowers the payment but proportionally reduces the months credited towards your pension.
People with many years of contributions behind them often prefer the reduction. People at the start, still building their position, usually do not. It is a choice to make with the individual person's figures in front of you.
Are the contributions I pay deductible?
Yes, compulsory social security contributions are deducted from income on a cash basis: what counts is the year in which they are actually paid.
Under the flat-rate scheme, deducting contributions is one of the few items that reduce the taxable base, so the timing of payment needs careful handling.
I opened in November. Do I pay for the whole year?
No, contributions on the minimum are scaled to the months you were actually enrolled, counted according to INPS rules.
The excess, by contrast, is calculated on the income actually earned in that period, so it is generally modest or nil in a first, partial year.
Let's talk
The contribution burden is estimated before you open
Knowing in advance how much the fixed contributions weigh is what separates a planned opening from one you find out about in instalments.
