Being self-employed means taking on the famous monthly freelance quotaThat Social Security receipt, which, along with your taxes, supports your social protection. Although it sometimes seems like a puzzle, the new system makes it more logical: you pay according to what you actually earn. The key today is understanding your net returns and which bracket you fall into. to choose a suitable contribution base and avoid surprises during the regularization process.
If you're planning your year or considering becoming self-employed, it's a good idea to know how the fee is calculated, which tables apply, and what options you have to adjust it to the reality of your business. There is a official simulator which allows you to estimate the fee and change it up to 6 times a yearFurthermore, the Treasury cross-references data with the Tax Office to issue refunds or claim discrepancies at the end of the fiscal year. Let's go into detail, with figures and practical examples, so you understand it clearly from the start.
How the self-employed contribution based on actual income works
Since the implementation of the real income model, each self-employed person is placed in one of 15 sections based on a forecast of monthly net returns. The fee is no longer fixed: it is calculated by applying a rate of 31,4% to the base you choose within the bracket (between the minimum and maximum allowed for that income range).
In 2025, the range of fees is wide and progressive: the minimum fees per bracket start at 200 euros and increase as your returns grow, while the maximum fees can reach amounts in the region of 1.542 euros if you choose high bases. This design aims to ensure that those with lower incomes pay less and those with higher incomes contribute more., with a direct correlation between contributions and benefits.
In addition, the Intergenerational Equity Mechanism (MEI) is added to your quote. In 2025, the MEI represents 0,8% of the contribution base. (one-tenth more than in 2024), with the aim of strengthening the sustainability of the pension system. That percentage is already included in the current rates.
Very important: you can adjust your quote relatively quickly. Allowed Change the base up to 6 times a year (every 2 months)so that you can adapt the fee to the actual evolution of your income without waiting for the annual adjustment.
- 15 sections based on projected monthly net returns.
- 31,4% rate on the chosen base within the section.
- Minimum fees from €200 and maximums that can reach €1.542 depending on the bracket/base.
- 0,8% MEI included in 2025.
Base tables 2025: reduced ranges and general table
The Budget Law establishes two tables: a reduced one for lower incomes and a general one for the rest. Each segment has a minimum and a maximum base. You can freely choose from these options. Below are the 2025 terms and conditions as they appear in the official information.
Reduced table 2025 (minimum and maximum bases)
| Section | Net returns | Minimum base (€) | Maximum base (€) |
|---|---|---|---|
| 1 | ≤ 670 € | 653,59 | 718,94 |
| 2 | > 670 and ≤ 900 € | 718,95 | 900,00 |
| 3 | > 900 and < 1.166,70 € | 849,67 | 1.166,70 |
The general table applies to the upper sections. Notice how the bases gradually climb, section by section., which allows you to adjust your coverage (and your fee) with considerable granularity.
General table 2025 (minimum and maximum bases)
| Section | Net returns | Minimum base (€) | Maximum base (€) |
|---|---|---|---|
| 1 | ≥ 1.166,70 and ≤ 1.300 € | 950,98 | 1.300,00 |
| 2 | > 1.300 and ≤ 1.500 € | 960,78 | 1.500,00 |
| 3 | > 1.500 and ≤ 1.700 € | 960,78 | 1.700,00 |
| 4 | > 1.700 and ≤ 1.850 € | 1.143,79 | 1.850,00 |
| 5 | > 1.850 and ≤ 2.030 € | 1.209,15 | 2.030,00 |
| 6 | > 2.030 and ≤ 2.330 € | 1.274,51 | 2.330,00 |
| 7 | > 2.330 and ≤ 2.760 € | 1.356,21 | 2.760,00 |
| 8 | > 2.760 and ≤ 3.190 € | 1.437,91 | 3.190,00 |
| 9 | > 3.190 and ≤ 3.620 € | 1.519,61 | 3.620,00 |
| 10 | > 3.620 and ≤ 4.050 € | 1.601,31 | 4.050,00 |
| 11 | > 4.050 and ≤ 6.000 € | 1.732,03 | 4.909,50 |
| 12 | > 6.000 € | 1.928,10 | 4.909,50 |
With these elements, the exact fee is obtained by multiplying the chosen base by the applicable rate. Thus, in 2025 you will see minimum fees ranging, depending on the bracket, from €200 to around €600, and higher odds if you choose maximum bases within each range.
Calculation of net earnings: rules by type of self-employed worker
Your position in the table depends on the net returns from all your economic activities during the year. That net return is calculated according to the Personal Income Tax regulations with particularities, and then a deduction for generic expenses is applied (7% or 3% depending on the case).
If you pay taxes under direct estimation, you subtract tax-deductible expenses from your income, add the self-employed contributions paid, and apply the deduction. In general, the deduction is 7% for individuals; for business or employment partners with certain shares and 90 days of registration in the year, the deduction is 3%.
In objective estimation (modules), the previous net income is used (with the specific reductions in agricultural, forestry and livestock activities) and An additional 7% is also deducted for generic expenses.Again, the deduction will be 3% in cases of business partners who meet the above criteria.
For self-employed business owners, all monetary or in-kind income derived from the company is taken into account, in addition to income from work for their role in the company and, where applicable, income from their own economic activity. The self-employed contribution is added and the 3% deduction is applied.which is specific to this group.
Remember that everything is calculated in annual terms and then averaged monthly. The contribution base is selected using that monthly average. within the corresponding bracket. And if as of 31/12/2022 you were contributing based on a higher amount than you should have been contributing to, you can continue to maintain that amount in 2025.
Practical example with real numbers
Imagine a self-employed person using direct estimation who in 2024 had an income of €22.000, deductible expenses of €4.820 and paid €295 in monthly fees (€3.540 per year). Their net income tax, including fees, would be 22.000 – 4.820 + 3.540 = €20.720.
Now we apply the 7% deduction for generic expenses: 20.720 × 0,07 = €1.450,4. Net computable income: 20.720 – 1.450,4 = €19.269,6 per yearDivided by 12, it comes out to €1.605,8 per month.
With €1.605,8 per month, it falls within the €1.500 to €1.700 range and could choose, for example, the minimum base of the range (€960,78). Applying the rate, the resulting fee for 2025 would be around €294 per month on a minimum basis.
If that self-employed person were a company owner, the general deduction would be 3% instead of 7%. The net monthly return would be somewhat higher and, in the example, would still be in the same bracket., with a similar minimum fee if the chosen base were the lowest in the range.
What will change in 2025 and how it has evolved since 2023
The system has been deployed since 2023 and major adjustments will be made in 2025. For the six lower brackets (up to €1.700 in income), the minimum fee is lower with approximate annual discounts between €80 and €428 depending on the bracket, provided that the minimum base of the range is chosen.
However, if your returns exceed €1.700, Minimum quotas increase in 2025 with estimated annual increases between €272 and €970 (at the minimum base), also depending on the bracket you are in.
Comparatively, in 2023 the minimum contributions ranged between €230 and €500, and in 2024 between €230,15 and €542,13 for minimum bases in the extreme ranges. In 2025, the minimum fee in the lowest bracket starts from €200, while in the higher brackets the minimum quota is higher than the previous year.
Another fact to remember: The minimum monthly payment per bracket in 2025, depending on the scale, will be between €200 and around €600 (approx.), and the maximum fee per segment reaches, in the higher ranges, around €1.542 when opting for high bases.
Change your base up to 6 times a year: official deadlines
To avoid being "out of balance," Social Security allows Up to 6 base changes per year, one every two monthsIt's a very useful mechanism if your income fluctuates or if the business takes a surprising turn for the better... or not so much.
- Applications from January 1st to the last day of February: effective March 1.
- March 1 to April 30: effective May 1st.

- The 1 31 July to August: effective September 1.
- From the 1 from September to the 31 from October: effective November 1.

All these changes are processed online through Import@ss, the Treasury's electronic headquarters. It's an agile process designed to synchronize the database with your revenue forecast. without having to wait until the end of the year.
Annual regularization, payments and surcharges
At the end of the year, Social Security compares your income declared in IRPF with the base on which you have contributed. If you've overpaid your contributions, you get a refund; if you've underpaid, you pay the difference.This comparison is being made retroactively and, for the first time, affects exercises under the new system.
Regarding the monthly charge, it's normal that if you set up a direct debit, the fee will be processed. the last day of every monthIf you are late, surcharges may apply, as with other Social Security and Tax obligations, so it is advisable to stay up to date to avoid extra costs.

Flat rate of €80 for new self-employed workers
If you register for the first time (or after the waiting period), you can take advantage of the flat rate. It consists of paying €80 per month for the first 12 months, regardless of your income during that initial period.
Furthermore, You can extend it for another 12 months if your net earnings remain below the minimum wage.This bonus allows you to start with less of a burden while you build your client portfolio.
Specific groups and situations
Self-employed collaborators: are relatives of the owner who collaborate in the business. They do not declare their own income and their minimum base cannot be less than the minimum wage.They can access specific bonuses and aid from the Administration.
Corporate self-employed: their minimum base cannot be lower than that of group 7 of the General Regime and they must have been at least 90 days in the condition during the year. In practice, many company members see a minimum contribution base of €1.000 with a monthly fee of around €310 if they choose the minimum, although If income is higher, the fee will also increase.For the calculation of returns, the general deduction is 3%.
PluriactivityIf you work both as an employee and as a self-employed individual, the contribution is adjusted in proportion to the working hours and the applicable regulations. There are specific details and possible returns if you surpass certain basics together.
Dependent self-employed worker (TRADE): despite its specific regulation for concentrating 75% or more of the turnover in one client, It is quoted under the same general rules. unless the regulations establish specific differences.
Active retirementIf you combine pension and work, you pay a separate contribution. It usually includes an 8% solidarity contribution and 3,3% for temporary disability., with the possibility of adding professional contingencies (0,9%).
Choosing a base: minimum, intermediate, or upgrading to improve performance?
Choosing the minimum base reduces current expenses, but It also limits sick leave benefits and future pensions.Increasing your coverage means paying more each month, in exchange for greater coverage, which may be of particular interest if you are approaching retirement or want to protect yourself against unforeseen events.
A typical example: earnings of €2.000 per month. With the minimum contribution base for your bracket, the monthly payment can be around €390–€415 depending on the table, but if you choose higher contribution bases, Fees are rising, and so are benefits.The decision depends on your objectives, cash flow, and time horizon.
As an alternative or complement, a temporary work incapacity insurance (TWI) This could be a good option if you're looking to bolster your sick leave coverage at a reasonable cost. There are situations where paying a moderate monthly premium provides additional income during your leave. without always needing to have the base at maximum.
For example: if a person is considering paying around €590 per month to contribute at the higher end of the scale versus €310 at the minimum level, the annual additional cost exceeds €3.000. A sick pay allowance of around €50 per month can cover a significant portion of the income loss during sick leave.It is a valid short-term strategy, although for a good pension it is usually advisable to increase the contribution base at some point or combine it with earmarked savings.
Simulator, procedures and other useful notes
The Treasury offers a simulator on Import@ss to calculate your fee based on forecasts and process changes. When you first register, they will ask you for your expected performance. And, if you were already in RETA, you can adjust the base throughout the year from the "Contribution base and earnings" service.
Those who, as of 31/12/2022, were contributing on a base higher than that which would result from their expected earnings can maintain that base in 2025And pay attention to those who came with the maximum base: for 2025 the PJC Order sets a ceiling of €4.909,50. allowing you to choose any base between the one they had and that new maximum..
Keep in mind that the system includes annual tables that may vary with social dialogue and public accounts. If you have any doubts, the simulator and your trusted accountant are your best allies. to avoid surprises when the regularization comes.
Looking ahead to 2026: proposals and adjustments in negotiations
There was an initial proposal for increases by 2026 that generated quite a bit of noise, with significant increases per segment. Subsequently, the Executive proposed freezing the first three tiers and moderating the increase of the others. (in the range of 1%–2,5% per month), leaving the final agreement to what is agreed upon in the social dialogue and in the parliamentary process.
For reference, certain estimated charts pointed to monthly increases ranging from a few euros in the middle ranges to just over €200 in the top range. In any case, these are proposals under discussion.Therefore, it is advisable to follow official updates before making structural decisions.
Obligations, partial payments and related taxation
The self-employed contribution is mandatory from the first day of activity and is paid monthly. In the month of registration or cancellation, you only pay for the actual days.not the full monthly payment, which alleviates the impact when there are changes in circumstances.
Beyond Social Security, remember your obligations to the Tax Office (VAT, Personal Income Tax and installment payments). The self-employed social security contribution does not include VAT and is deductible from income tax as an expense. No invoice is required, but it's not a tax: it's your contribution to Social Security for coverage of contingencies and pensions.
What factors influence your payment? Primarily, your returns and the base you choose within the bracket. They also include bonuses (flat rate, collaborator, etc.) and situations such as multiple employmentThe autonomous community may offer additional aid, but the calculation of the quota is state-run and does not depend on the sex of the worker.
If you need to invoice from day one, consider using an invoicing tool and an accounting firm. You'll have control over income, expenses, and forecastsThis makes it easier to adjust your base and avoid discrepancies in the annual adjustment.
The great advantage of the current system is the flexibility to align quotes with the reality of the business. Know the sections, use the simulator, and check your base every two months. It allows you to optimize your quota, improve your protection, and avoid surprises at the end of the year.
