Small Business Tax in Italy

Italian businesses face a layered tax environment built around two core levies for companies and a simplified substitute-tax option for small sole traders. Understanding which regime applies, how INPS social contributions interact with income tax, and when quarterly VAT obligations fall due is the starting point for any Italy-based business owner.

Italy country overview provides background on the broader Italian legal and regulatory context.

What corporate income taxes apply to Italian SRL and SPA companies?

IRES (Imposta sul Reddito delle Societa) is the Italian corporate income tax, levied at a standard rate of 24% on the worldwide taxable profits of resident corporations. The tax base broadly follows accounting profit adjusted under the rules of the Testo Unico delle Imposte sui Redditi (TUIR, DPR 917/1986). Deductible costs include most operating expenses, depreciation at statutory rates, and a portion of financial interest subject to the 30%-of-EBITDA thin-capitalisation cap. IRES applies to SRL (Societa a Responsabilita Limitata), SPA (Societa per Azioni), and other corporate forms resident in Italy or deriving Italian-source income.

IRAP (Imposta Regionale sulle Attivita Produttive, Decreto Legislativo 446/1997) adds a regional production tax at a standard base rate of 3.9% on net production value -- broadly operating profit before financial items and certain personnel costs. Regional governments may adjust the rate within a 0.92 percentage-point band, so effective IRAP ranges across Italy from approximately 2.98% to 4.82% for standard corporates. The combined ordinary rate for a non-financial Italian SRL is therefore approximately 27.9%, before regional variation. Note that IRAP was abolished for individual taxpayers without employees from the 2022 tax year onward, but remains fully applicable to corporate entities such as SRL and SPA. [1][2]

What is the IRES premiale 2025 reduced rate?

The Italian Budget Law for 2025 (Law 207/2024, 30 December 2024) introduced the IRES premiale -- a temporary reduced corporate income tax rate of 20% for fiscal year 2025 only, in place of the ordinary 24% rate. Three cumulative conditions must be met:

1. At least 80% of fiscal year 2024 profits must be set aside in a special equity reserve and held there for at least two years.
2. The company must invest the higher of 30% of retained 2024 profits or 24% of 2023 profits in qualifying Industry 4.0 or Transition 5.0 tangible or intangible capital assets by October 2026, with a minimum investment floor of EUR 20,000.
3. Employment must not have been reduced in 2024, must increase by at least 1% in 2025, and the firm must not have accessed the CIG (Cassa Integrazione Guadagni) wage guarantee fund in the relevant fiscal year.

The IRES premiale is applied directly in the corporate income tax return (Modello Redditi SC) without prior notification, and is fully cumulative with Transition 4.0 and 5.0 tax credits. The reserve must not be distributed before 31 December 2026, and transferred or diverted assets trigger recapture within five years. This incentive targets only fiscal year 2025; no extension into 2026 has been legislated as of the date of this review. [3]

Who qualifies for the regime forfettario flat-tax?

The regime forfettario (Law 190/2014 as amended by Law 145/2018 and Law 197/2022) is a substitute-tax regime for individuals -- sole traders (ditta individuale) and self-employed professionals (lavoratori autonomi) -- whose annual gross revenue or professional fees did not exceed EUR 85,000 in the prior tax year. Revenue above EUR 100,000 in the current year triggers an immediate mandatory exit to the ordinary regime from that same tax year.

Additional eligibility conditions include: personnel or collaborator costs below EUR 20,000 per year; other employment or pension income not exceeding EUR 35,000; no ownership or control of a company operating in the same sector; and the business activity must not be directed predominantly toward a current or former employer.

The core tax mechanic applies an ATECO-code-specific profitability coefficient (coefficiente di redditivita) to gross revenue to arrive at the flat-rate taxable base. Coefficients range from 40% (traders in goods) to 78% (professional services and teaching). The substitute tax rate is:

• 15% on the coefficient-reduced taxable base for established businesses.
• 5% for genuinely new activities during the first five tax periods (five-year startup rate, provided the activity has not been carried on in the prior three years and does not represent a continuation of a prior activity).

Taxpayers under the regime forfettario are exempt from VAT (no VAT charged on invoices, no input-VAT recovery), exempt from IRAP, exempt from the mandatory ISA reliability index compliance, and not subject to withholding tax on professional income. Electronic invoicing via the Sistema di Interscambio (SDI) in FatturaPA XML format is mandatory from 1 January 2024 regardless of regime, following the extension of the e-invoicing mandate to all VAT holders. INPS contributions remain due but the contribution base is the coefficient-reduced income, and artisans and traders registered with INPS gestione artigiani/commercianti may apply a 35% reduction on contribution rates when under the forfettario regime. [4][5]

How does the ordinary IRPEF regime work for sole traders?

Sole traders and self-employed professionals who do not qualify for or elect out of the regime forfettario fall under the ordinary IRPEF (Imposta sul Reddito delle Persone Fisiche) regime. Net business or professional income (receipts minus deductible costs including INPS contributions paid) is added to all other personal income and taxed at progressive national brackets.

IRPEF brackets effective from 1 January 2025:

Regional surcharges (addizionale regionale IRPEF) add approximately 1.23% to 3.33% depending on the region; municipal surcharges (addizionale comunale) add up to 0.9% on the same base. Sole traders on the ordinary regime also remain subject to IRAP if they employ staff, and are required to comply with ISA reliability index filing and VAT obligations in full. Actual costs are deductible (versus the lump-sum coefficient method under forfettario), which may favour ordinary-regime filing when a business carries substantial deductible expenses. [6]

What are the INPS social contribution obligations?

INPS social contributions are compulsory alongside income tax and represent a significant additional cash-flow obligation for Italian small businesses and self-employed individuals.

For artisans and traders registered with the INPS gestione artigiani e commercianti, the 2025 rates set by INPS circular are:

• Artisans (artigiani): 24% of net income
• Traders (commercianti): 24.48% of net income
• Plus a monthly maternity contribution of EUR 0.62

These rates apply from a minimum income floor of EUR 18,200 (below which a minimum fixed contribution is due regardless of actual income) up to a maximum contribution ceiling of EUR 123,580. For taxpayers under the regime forfettario, the contribution base is the coefficient-reduced taxable income, and a 35% reduction on the applicable rate is available to forfettario holders enrolled in the gestione artigiani/commercianti scheme.

Freelancers and professionals not covered by a sector-specific pension fund contribute to INPS Gestione Separata at 26.07% of net taxable income in 2025, up to the annual ceiling of EUR 120,607. The Gestione Separata rate applies in full regardless of tax regime -- the 35% forfettario reduction does not apply to Gestione Separata contributors. [7]

What are the quarterly VAT and e-invoicing obligations?

Italian VAT (IVA -- Imposta sul Valore Aggiunto) is governed by DPR 633/1972 and applies at a standard rate of 22%, with reduced rates of 10%, 5%, and 4% for specified goods and services. Most small businesses not under the regime forfettario register for VAT and file periodic returns.

Quarterly liquidation (liquidazione IVA trimestrale) is available to businesses with annual turnover below EUR 400,000 for service activities or EUR 800,000 for goods activities. Quarterly net VAT due is payable by the 16th day of the second month following the end of each quarter:

• Q1 (January to March): due 16 May
• Q2 (April to June): due 16 August
• Q3 (July to September): due 16 November
• Q4 (October to December): settled in the annual VAT return (Dichiarazione IVA) by 30 April

A 1% surcharge applies to quarterly payers in lieu of monthly filing. Businesses above the quarterly thresholds file monthly. The annual VAT return is due by 30 April of the following year regardless of payment frequency.

Electronic invoicing (fatturazione elettronica) via the government Sistema di Interscambio (SDI) platform has been mandatory for all domestic B2B and B2C transactions since 1 January 2019. From 1 January 2024, the mandate was extended to all VAT holders without exception, including those previously exempt -- including businesses under the regime forfettario. Invoices must be issued in FatturaPA XML format, transmitted through accredited channels (PEC, SDICoop, SDIFTP, or the Agenzia delle Entrate web portal), and assigned the correct regime code (RF05 for forfettario, RF01 for ordinary). New technical specifications FatturaPA v1.9 apply in 2025, introducing document type TD29 for irregular supplier invoices. [8][9]

Italian VAT registration, periodic filing, and e-invoicing obligations involve several interacting deadlines and technical requirements. A qualified tax professional familiar with Italian VAT can help businesses meet obligations and avoid late-payment surcharges.
