If you work as a Partita IVA holder, one of the most common questions is: how much actually ends up in my pocket? Going from gross revenue to net income isn't as straightforward as it is for an employee, because social security contributions, taxes, profitability coefficients, and deductible expenses come into play, all varying based on your chosen tax regime.
In this comprehensive guide, we explain step by step how to calculate your Partita IVA net income in 2026, with formulas, real-world examples, and our Partita IVA net income calculator that lets you run an instant simulation by entering your actual figures.
What is net income for a Partita IVA holder
Net income is the amount left over after subtracting all mandatory cost items from your gross revenue: INPS contributions or professional fund payments, taxes (IRPEF or flat-rate substitute tax), regional and municipal surcharges, and business expenses. It represents your real earnings -- what you can actually spend or save.
For an employee, the calculation is relatively straightforward, since the employer withholds taxes from the paycheck. For a Partita IVA holder, however, the process is more complex and changes significantly depending on the tax regime adopted.
Flat-rate regime vs standard regime: the key differences
In 2026, the two main tax regimes for individual Partita IVA holders are the flat-rate regime (regime forfettario) and the simplified standard regime (regime ordinario semplificato). Understanding the differences is essential for accurately estimating your net income.
Flat-rate regime (regime forfettario) 2026
The flat-rate regime is available to those with annual revenue up to 85,000 euros and features simplified taxation. The main characteristics are:
- Substitute tax: 15% on taxable income (reduced to 5% for the first 5 years of business activity)
- Profitability coefficient: a fixed percentage that varies by ATECO code (from 40% to 86%), applied to revenue to determine taxable income
- No VAT deduction: you cannot deduct VAT on purchases, but you also don't charge it to clients
- INPS contributions: Gestione Separata (26.07%) or Artisans/Traders (~24%) on taxable income
For a deeper dive into tax calculations under the flat-rate regime, see our flat-rate regime guide with a dedicated simulator.
Simplified standard regime (regime ordinario semplificato)
The standard regime is mandatory for those exceeding 85,000 euros in revenue or who don't meet the flat-rate regime requirements. It includes:
- Progressive IRPEF brackets: progressive rates from 23% to 43% (with 3 brackets in 2026)
- Surcharges: regional (0.9%-3.33%) and municipal (up to 0.8%)
- Deductible costs: all business-related expenses are deductible from income
- VAT: charged to clients and deducted on purchases
- INPS contributions: calculated on income net of deductible expenses
How to calculate net income: the step-by-step formula
Here is the calculation process for both regimes.
Flat-rate regime formula
| Step | Formula | Example (revenue 40,000 €, coeff. 78%) |
|---|---|---|
| 1. Taxable income | Revenue × Profitability coefficient | 40,000 × 78% = 31,200 € |
| 2. INPS contributions | Taxable income × INPS rate | 31,200 × 26.07% = 8,134 € |
| 3. Tax base | Taxable income − INPS contributions | 31,200 − 8,134 = 23,066 € |
| 4. Substitute tax | Tax base × 15% (or 5%) | 23,066 × 15% = 3,460 € |
| 5. Net income | Revenue − Contributions − Tax | 40,000 − 8,134 − 3,460 = 28,406 € |
In this example, out of 40,000 euros in revenue, approximately 28,400 euros remain in your pocket, equal to 71% of gross revenue.
Standard regime formula
| Step | Formula | Example (revenue 60,000 €, expenses 15,000 €) |
|---|---|---|
| 1. Gross income | Revenue − Deductible expenses | 60,000 − 15,000 = 45,000 € |
| 2. INPS contributions | Income × INPS rate | 45,000 × 26.07% = 11,732 € |
| 3. IRPEF taxable income | Income − Contributions | 45,000 − 11,732 = 33,268 € |
| 4. IRPEF + surcharges | Progressive brackets + surcharges | ~7,900 € (IRPEF) + ~500 € (surcharges) = ~8,400 € |
| 5. Net income | Revenue − Expenses − Contributions − IRPEF | 60,000 − 15,000 − 11,732 − 8,400 = 24,868 € |
Under the standard regime, out of 60,000 euros in revenue with 15,000 euros in expenses, approximately 24,870 euros remain, equal to 41% of revenue.
2026 profitability coefficients by ATECO code
If you're under the flat-rate regime, the profitability coefficient is the factor that most impacts your net income. Here are the main ones:
| Activity | Coefficient |
|---|---|
| Trade (wholesale and retail) | 40% |
| Trade intermediaries | 62% |
| Accommodation and food services | 40% |
| Professional and scientific activities | 78% |
| Construction and real estate | 86% |
| IT and communication activities | 67% |
| Financial and insurance activities | 78% |
| Other economic activities | 67% |
A lower coefficient means a smaller portion of your revenue is taxed, resulting in a proportionally higher net income. For example, a trader with a 40% coefficient pays taxes on only 40% of revenue, while a professional with 78% is taxed on nearly everything.

5 common mistakes in calculating net income
Many professionals and freelancers make recurring mistakes that lead to overestimating their actual net earnings. Here are the most frequent ones:
- Confusing revenue with income: revenue is what you collect, net income is what's left after taxes and contributions. The difference can be as much as 40-60%.
- Forgetting social security contributions: INPS or professional fund contributions are often the heaviest cost item, sometimes even exceeding the taxes themselves.
- Not accounting for tax advances: in the first year of business, you pay both the current year's balance and advances for the following year, creating a double burden.
- Ignoring surcharges: under the standard regime, regional and municipal surcharges can add an extra 2-4% tax burden.
- Underestimating non-deductible expenses: under the flat-rate regime, no expenses are deductible (the coefficient is fixed). If you have significant actual expenses, the standard regime might be more beneficial.
When the flat-rate regime is better and when the standard regime wins
The choice of tax regime directly affects your net income. As a general rule:
The flat-rate regime is advantageous when actual business expenses are low (below the flat-rate percentage) and revenue stays under 85,000 euros. This is typically the case for consultants, developers, and freelancers who primarily work with a computer and have few overhead costs.
The standard regime is advantageous when actual expenses exceed the flat-rate allowance, when you work with EU/non-EU clients (to recover VAT), or when you have significant investments to deduct (equipment, office rent, contractors).
To compare both scenarios with your actual numbers, use the Partita IVA net income simulator and try both regimes.
2026 tax deadlines for Partita IVA holders
To plan your cash flow and know when your net income will actually be available, it's useful to know the key deadlines:
| Deadline | What you pay |
|---|---|
| June 30, 2026 | Previous year tax balance + 1st advance payment for the current year |
| July 30, 2026 | Balance + advance with 0.40% surcharge (for those who defer) |
| September 16, 2026 | INPS Gestione Separata contributions (2nd installment) |

Frequently asked questions
How much net income remains from 30,000 euros in revenue under the flat-rate regime?
With a 78% profitability coefficient (professionals) and a 15% tax rate, from 30,000 euros in revenue the net income is approximately 21,300-22,000 euros. With the reduced 5% rate (first 5 years), it rises to about 23,500 euros. The result varies based on the ATECO coefficient and social security fund. Use the calculator for a precise estimate.
What is the total tax percentage on a flat-rate Partita IVA?
The total tax burden (taxes + contributions) under the flat-rate regime ranges between 25% and 45% of revenue, depending on the profitability coefficient and social security fund. The substitute tax is 15% (or 5% for new businesses), but INPS contributions add an additional 24-26% on taxable income.
How do you calculate net income from a gross fee as a Partita IVA holder?
To calculate net from a gross fee: 1) determine taxable income by applying the profitability coefficient (flat-rate) or subtracting expenses (standard); 2) calculate INPS contributions on taxable income; 3) calculate the substitute tax or IRPEF on the tax base (income minus contributions); 4) subtract contributions and taxes from revenue. Our simulator automates all these steps.
Is it better to open a flat-rate Partita IVA or stay employed?
It depends on projected revenue and expenses. As a rough guideline, to earn the equivalent of an employee with a 30,000 euro net annual salary, under the flat-rate regime you need to invoice at least 42,000-48,000 euros per year (considering that freelancers also pay contributions, insurance, accountant fees, and don't have paid vacation or severance pay). Compare the numbers with the net salary calculator for employees.
Can INPS contributions be deducted under the flat-rate regime?
Yes, mandatory social security contributions paid are deductible from taxable income even under the flat-rate regime. This means they reduce the base on which the 15% (or 5%) substitute tax is calculated. It's the only deduction allowed under the flat-rate regime and is applied automatically in our calculator.
Conclusion
Calculating net income as a Partita IVA holder requires attention to many variables: tax regime, profitability coefficient, INPS rate, potential deductions, and surcharges. Don't rely on rough estimates: use our Partita IVA net income calculator 2026 to get a clear picture and make informed decisions about your business.
