How the Flat-Rate Tax Regime Calculator Works

The flat-rate tax regime calculator is a free and easy-to-use tool that allows you to accurately calculate taxes and contributions under the simplified tax regime for VAT-registered individuals. This tool is designed for professionals, freelancers, artisans, and traders who want to understand in advance what their net income will be after paying substitute taxes and INPS contributions.

The flat-rate regime is a simplified taxation system introduced to support small businesses and self-employed workers, with annual revenues not exceeding 85,000 euros. Through this calculator, you can simulate different configurations: from choosing the profitability coefficient specific to your business sector (professional services at 78%, trade at 67%, other services at 62%, or agricultural sector at 40%), to applying the correct tax rate (5% for the first five years of new businesses or the standard 15%).

Main use cases for the calculator

This tool proves particularly useful in various professional and tax planning situations:

  • Starting a new business: Those considering opening a VAT number can estimate their net income in advance, comparing different revenue scenarios and verifying the convenience of the flat-rate regime compared to other tax regimes.
  • Annual financial planning: Already active professionals can use the calculator to plan expenses, savings, and investments, having a clear view of the taxes and contributions to set aside during the year.
  • Comparison between business sectors: It is possible to simulate the tax burden by applying different profitability coefficients, useful for those considering a sector change or adding new complementary activities.
  • Economic sustainability assessment: Before accepting an assignment or setting your professional rates, the calculator allows you to understand how much you will actually earn after taxes, avoiding unpleasant surprises at the end of the year.
  • Tax optimization: By comparing the reduced 5% rate (for new businesses) with the standard 15% rate, you can evaluate tax savings in the early years of business and plan initial investments accordingly.

The final calculation result transparently shows the breakdown between taxes, contributions, and net income, accompanied by a visual chart that facilitates immediate understanding of your tax situation. Additionally, you can export the results in PDF format to save them, share them with your accountant, or use them as a reference for financial planning.

Frequently Asked Questions (FAQ) about the Flat-Rate Tax Regime

What is the flat-rate regime and who can access it?

The flat-rate regime is a simplified taxation system dedicated to individual VAT-registered professionals who do not exceed 85,000 euros in annual revenue. It is accessible to individuals who carry out business activities, arts, or professions, with some specific exclusions (such as those who simultaneously participate in partnerships or have received employment income exceeding 30,000 euros in the previous year).

How is taxable income calculated in the flat-rate regime?

Taxable income is calculated by applying a profitability coefficient established by law based on the ATECO code of your business activity to the annual revenue. For example, for professional services the coefficient is 78%, so on a revenue of 30,000 euros, the taxable income will be 23,400 euros. Taxes and contributions are then calculated on this amount.

What is the difference between the 5% and 15% tax rates?

The reduced 5% rate is reserved for new businesses (startups) for the first five years from the date of opening the VAT number, provided that the activity does not constitute a mere continuation of a previously carried out activity. After this period, or for those who do not meet the requirements, the standard 15% rate is applied to the taxable income.

Are INPS contributions mandatory in the flat-rate regime?

Yes, social security contributions are mandatory and vary depending on the professional category. Professionals enrolled in the INPS Separate Management pay 25.72% of the taxable income, while artisans and traders pay approximately 24%. Those who are already retired or have other forms of social security coverage may be exempt, but it is always advisable to verify your position with a consultant.

Can I deduct expenses in the flat-rate regime?

No, in the flat-rate regime it is not possible to analytically deduct expenses incurred for the business (such as rent, equipment, travel, or training). The profitability coefficient applied to the revenue already accounts for all average sector expenses on a flat-rate basis. This greatly simplifies accounting, but it means you cannot claim specific costs as deductions.

When is the flat-rate regime more convenient than the ordinary regime?

The flat-rate regime is generally convenient for those who have few deductible expenses and revenues within the 85,000 euro threshold. The fixed rate of 15% (or 5% for new businesses) is very advantageous compared to the progressive IRPEF rates of the ordinary regime, which can reach up to 43%. However, those who incur many documentable expenses (for example, in trade with high merchandise purchase costs) may find the ordinary regime more convenient, as it allows full deduction of those costs.

What happens if I exceed 85,000 euros in revenue?

If revenue exceeds 85,000 euros but remains within 100,000 euros, you can stay in the flat-rate regime for the current year, but from the following year you will be required to switch to the ordinary regime. If, however, you exceed 100,000 euros, you immediately exit the flat-rate regime in the current year and will need to apply VAT on invoices issued from the moment the threshold is exceeded.

Do I need to charge VAT on my invoices in the flat-rate regime?

No, those who adhere to the flat-rate regime do not charge VAT on invoices issued to clients and cannot deduct VAT on purchases. Invoices must include the statement "Transaction carried out pursuant to Art. 1, paragraphs 54 to 89, of Law No. 190/2014 - Flat-rate regime - Transaction without application of VAT". This simplifies accounting management but can be a disadvantage when working primarily with companies that may prefer invoices with deductible VAT.

How can I check which profitability coefficient applies to my business?

The coefficient depends on the ATECO code of your main business activity registered with the Chamber of Commerce. You can verify it by consulting the official tables of the Revenue Agency or by asking your accountant. The most common ones are: 78% for professionals (consultants, lawyers, engineers), 67% for trade, 62% for other services (hairdressers, plumbers, electricians), and 40% for the agricultural sector.

Does this calculator replace the advice of an accountant?

No, this tool is designed to provide an indicative estimate useful for planning, but it does not replace the professional advice of a qualified accountant. Each tax situation has specific characteristics (for example, the presence of other income, tax credits, particular family situations) that can affect the final calculation. We always recommend verifying the results with your tax consultant before making important decisions.
