Missing Italy's June 30 IRES advance payment costs 25% of the unpaid amount under the reformed penalty regime (D.Lgs. 87/2024, effective September 1, 2024). But self-correcting within 14 days costs only 1.4% at most. The gap between these two numbers — 25% vs. 1.4% — is the entire case for understanding the ravvedimento operoso self-correction system.
Most English-language sources still cite the outdated 30% standard penalty rate that was reduced to 25% by D.Lgs. 87/2024. Foreign SRL owners often don't know the advance payment calendar at all, confusing the November 30 annual return deadline with the June 30 advance payment date — or assuming that the first-year SRL owes no taxes at all when in fact it must begin acconti in Year 2.
This guide provides the correct current penalty rates (updated for D.Lgs. 87/2024), the complete ravvedimento operoso tiered table for self-correction, the June/November advance payment calendar with a worked example, and confirmation that first-year SRLs typically owe no advance payments in Year 1 — but must be ready for Year 2.

Italy's Advance Tax Payment System: The June and November Deadlines
Italy's IRES advance payment system (acconti) requires companies to pre-pay estimated current-year IRES in two installments, based on the prior year's IRES liability. All payments are made via Modello F24 — electronic submission, typically managed by the commercialista.
| Payment | Deadline | Amount | Extension Option | Notes |
|---|---|---|---|---|
| Primo acconto (first) | June 30 | 40% of prior-year IRES | July 31 with 0.40% surcharge | Via F24; IRAP follows same schedule |
| Secondo acconto (second) | November 30 | 60% of prior-year IRES | No extension | Same calendar date as Modello Redditi SC filing |
| Annual return (Modello Redditi SC) | November 30 | Balance (saldo) if current-year IRES > advance paid | — | Filed by commercialista |
Worked example — historical method:
- Prior-year IRES paid: €100,000
- Primo acconto (June 30): 40% × €100,000 = €40,000 due
- Secondo acconto (November 30): 60% × €100,000 = €60,000 due
- Total advance payments: €100,000
- If actual FY IRES = €120,000: additional balance of €20,000 due with the Modello Redditi SC filing
Two calculation methods:
Historical method (metodo storico) — default: Base advance payments on 100% of the prior year's IRES. This is the safe harbour: if prior-year IRES ≥ current-year IRES, there is no underpayment risk. Advisors recommend this approach for most SRLs.
Forecast method (metodo previsionale): Pay 100% of estimated current-year IRES. Useful only if current-year profit is clearly below prior-year (e.g., the SRL had an exceptional prior year). Risk: if current year is higher than estimated, the underpayment triggers the full 25% penalty plus interest.
De minimis rule: If prior-year IRES was ≤€51.65 (effectively a zero-profit year), no advance payment is required regardless of year.
Extension: The June 30 primo acconto can be extended to July 31 with a 0.40% surcharge on the total amount. Useful for SRLs whose annual accounts are not yet approved by June 30.

First-Year SRL: Do You Owe Any Advance Payments?
This is one of the most common anxieties for newly incorporated Italian SRL owners. The answer is usually reassuring — but Year 2 requires preparation.
| Year | Prior-Year IRES? | Acconto Required? | Notes |
|---|---|---|---|
| Year 1 (incorporation year) | None — no prior return | Generally NO | No base for historical method; forecast method possible but rarely used |
| Year 2 | Yes (Year 1 IRES exists) | YES | 40% of Year 1 IRES by June 30; 60% by November 30 |
| Year 3+ | Yes | YES | Normal ongoing cycle |
Year 1 explanation: A newly incorporated Italian SRL has no prior-year IRES return. The historical method has no base to work from. The forecast method is technically available but advisors almost never recommend it in Year 1 — the forecast is inherently unreliable in the first operating year, and an underestimate triggers penalties.
IRAP: The same logic applies. First-year SRLs generally owe no IRAP acconti. Acconti begin in Year 2 for both IRES and IRAP.
Planning for Year 2: Budget for acconti starting in Year 2. The Year 2 primo acconto (June 30) will be 40% of whatever IRES the SRL reported for Year 1 — even if Year 1's Modello Redditi SC has not yet been filed, the payment is due based on the expected Year 1 IRES. The commercialista typically calculates this in advance.
SRL with acquired business: If the SRL acquired an existing business or commenced operations before formal incorporation with taxable activity, the Year 1 position may be different. Specialist advice is needed.
Penalties: The Post-September 2024 Reform
D.Lgs. 87/2024 (effective September 1, 2024) reduced the standard late-payment penalty from 30% to 25%. This is one of the most important recent changes in Italian tax penalty law — and most English-language guides still show the outdated 30% rate.
| Violation | Pre-September 2024 Rate | Post-September 2024 Rate (D.Lgs. 87/2024) |
|---|---|---|
| Late payment (standard) | 30% | 25% |
| Underpayment of acconti | 30% | 25% |
| Unfaithful declaration | 90–180% | 70% |
| Late filing within 90 days | ~0.1%/day (min €250) | ~0.1%/day (min €250) — unchanged |
| Omessa dichiarazione (no return filed) | 120–240% | 120% |
Practical impact: A missed €10,000 IRES acconto now generates a €2,500 penalty (previously €3,000) plus 5% annual interest on the outstanding amount (2024 MEF rate). The reduction is welcome but the penalty remains substantial.
Why most English pages still show 30%: The D.Lgs. 87/2024 reform took effect on September 1, 2024. Pages not updated since that date show the old rate. Any source citing 30% as the current standard penalty for late payment of IRES acconti is using outdated information.
Omessa dichiarazione (failure to file a return at all): The penalty is now 120% of tax due (reduced from the previous 120–240% range). This remains far more severe than any late payment penalty. If a return has not been filed, immediate professional intervention is required — every day of delay increases the exposure.
Criminal thresholds (D.Lgs. 74/2000): For very large-scale tax evasion — generally exceeding €150,000 of evaded tax per year — criminal prosecution is possible. This is well above typical SME SRL situations but relevant for MNE groups with significant Italian operations.

Ravvedimento Operoso: Self-Correction Before the Tax Authority Acts
Ravvedimento operoso (D.Lgs. 472/1997, as amended) is Italy's voluntary self-correction mechanism. It allows a taxpayer to pay overdue taxes with dramatically reduced penalties — but only before Agenzia delle Entrate initiates a formal audit or sends a formal assessment notice.
The complete tiered table (current rates):
| Tier | Time Since Missed Deadline | Penalty Rate | Key Point |
|---|---|---|---|
| Sprint | Within 14 days | 0.1% per day (max 1.4%) | Act immediately — cheapest tier |
| Breve | 15–30 days | 1.5% | Still dramatically lower than 25% |
| Medio | 31–90 days | 1.67% | |
| Lungo | Within annual tax return filing | 3.75% | |
| Biennale | Within 2 years of violation | 4.29% | |
| Ultra-biennale | After 2 years | 5% | Last self-correction opportunity |
| No self-correction | Caught in audit | 25% (D.Lgs. 87/2024) | Cannot self-correct once audit starts |
Plus: 5% annual legal interest (2024 MEF rate) on the unpaid tax amount, calculated from the original due date.
Worked example:
- SRL missed the June 30 primo acconto (€40,000 unpaid)
- Self-corrects 20 days later (Breve tier): 1.5% × €40,000 = €600 penalty
- Plus 5% annual interest for 20 days: €40,000 × 5% × (20/365) = approximately €110
- Total cost of self-correction: approximately €710
- vs. being caught in a later audit: 25% × €40,000 = €10,000 penalty + accumulated interest
The fundamental rule: Ravvedimento operoso is available only before Agenzia delle Entrate initiates formal audit procedures or sends a formal notice. Once an audit is open — or even after the taxpayer receives a formal letter (invito al contraddittorio or questionario) — self-correction is no longer available.
Practical steps for self-correction:
- Calculate the exact unpaid amount (tax only — penalties and interest are calculated separately)
- Determine the correct tier based on the number of days since the missed deadline
- Calculate the penalty: unpaid tax × penalty rate
- Calculate interest: unpaid tax × 5% × (days outstanding / 365)
- Prepare the corrective F24 payment using the correct codice tributo for the tax principal, a separate codice tributo for the penalty, and a separate codice tributo for the interest
- File the corrective F24 and retain documentation
Step 5 is where errors occur: Using wrong codice tributo values — or combining tax, penalty, and interest in a single wrong entry — results in a failed correction that does not shield against the standard 25% penalty. Attempting ravvedimento operoso without the commercialista's guidance is not recommended.
Concordato Preventivo Biennale: Locking In Your Tax in Advance
For eligible businesses, Italy offers a forward-looking mechanism to eliminate advance payment uncertainty: the Concordato Preventivo Biennale (CPB), introduced by D.Lgs. 13/2024.
How it works: Eligible taxpayers agree with Agenzia delle Entrate on a fixed taxable income figure for the next two years. If actual income exceeds the agreed figure, no additional tax is due. If actual income is lower, the agreed amount is still due. In exchange, audit risk is significantly reduced during the CPB period.
Who is eligible:
- Taxpayers subject to ISA (Indici Sintetici di Affidabilità Fiscale — Italy's synthetic reliability indices for small businesses and freelancers)
- Regime forfettario holders
Who is NOT eligible:
- Large SRLs outside the ISA regime
- Newly incorporated SRLs in their first year (no ISA base)
- Companies with complex international structures
Benefits:
- Eliminates acconto uncertainty — no risk of underpaying acconti for 2 years
- Reduces audit risk during the CPB period
- Allows reliable tax budgeting for the SRL's 2-year planning horizon
2024 cycle: The 2024–2025 CPB opt-in deadline was October 31, 2024 — now past. Watch for the 2026–2027 cycle announcement.
IRES premiale (pending): Law 207/2024 introduced a proposed 20% reduced IRES rate (down from 24%) for companies that reinvest a minimum portion of profits and maintain or increase employment. As of early 2025, the implementing regulations have not yet been finalized — watch for Agenzia delle Entrate guidance on the specific conditions and opt-in procedure.
FAQ
Q: What is the IRES rate in Italy for 2024?
IRES (Imposta sul Reddito delle Società) is 24% flat on net taxable profit for Italian companies (SRL, SPA). This rate has been unchanged since 2017. Italian companies also pay IRAP at 3.9% standard rate on net production value, following the same advance payment schedule.
Q: When are advance tax payments (acconti) due in Italy?
IRES advance payments are split into two installments: the first (40% of prior-year IRES) is due June 30 (extendable to July 31 with a 0.40% surcharge); the second (60%) is due November 30 — the same date as the Modello Redditi SC filing. IRAP follows the identical schedule.
Q: What happens if I miss an advance tax payment in Italy?
A standard penalty of 25% of the unpaid amount applies (D.Lgs. 87/2024, effective September 1, 2024), plus 5% annual interest. However, using ravvedimento operoso self-correction, the penalty can be reduced to as low as 0.1% per day (within 14 days of the missed deadline) or 1.5% (within 30 days) — a dramatic reduction from the standard 25%.
Q: What is ravvedimento operoso in Italy?
Ravvedimento operoso is Italy's voluntary self-correction mechanism, allowing taxpayers to pay overdue taxes with a reduced penalty before Agenzia delle Entrate initiates a formal audit. Tiered penalty rates range from 0.1% per day (within 14 days) to 5% (after 2 years), all significantly lower than the standard 25% penalty. Plus 5% annual interest on the unpaid amount. Self-correction is not available once a formal audit has begun.
Q: Does a newly incorporated SRL need to pay advance taxes in its first year?
Generally no. A first-year SRL has no prior-year IRES return, so there is no base for the historical calculation method. Advance payments (acconti) typically begin in Year 2, based on the IRES reported for Year 1. Budget for the first Year 2 primo acconto (40% of Year 1 IRES) falling due on June 30 of the second year of operations.
Q: What is the codice tributo and why does it matter for F24 payments?
A codice tributo is a specific numeric code assigned to each type of Italian tax payment — a different code exists for IRES advance payments, IRES balances, IRAP, VAT, penalty payments, and interest payments. When filing ravvedimento operoso through an F24 form, the principal tax, the penalty, and the interest must each be entered with their specific and separate codice tributo. Using the wrong code — or combining amounts in a single entry — results in a failed correction that does not extinguish the original liability. Agenzia delle Entrate does not automatically correct F24 errors; professional management of this step is essential.
Q: What is the difference between the historical method and forecast method for Italian acconti?
The historical method (metodo storico) bases advance payments on 100% of the prior year's IRES — the safe harbour approach that eliminates underpayment risk if the current year is similar to or worse than the prior year. The forecast method (metodo previsionale) allows payment of 100% of estimated current-year IRES — useful only when current-year profits are clearly and materially lower than the prior year. The forecast method is risky: if actual profits exceed the estimate, the underpaid portion triggers the full 25% penalty plus interest. Most Italian commercialisti recommend the historical method unless there is a well-documented decline in profitability.
Q: Can ravvedimento operoso be used to correct an omessa dichiarazione (missing tax return)?
Ravvedimento operoso can reduce penalties on an omessa dichiarazione if the return is filed before Agenzia delle Entrate formally initiates an audit or issues an assessment. The penalty for filing late within 90 days of the original deadline: 1/10 of the minimum penalty with progressive time-tiering. After 90 days and before audit commencement, higher tiered rates apply but self-correction remains available. Filing a tax return after the 90-day window but before any formal audit action significantly reduces the standard 120% omessa dichiarazione penalty. Once an audit is formally opened, self-correction is no longer available.
Q: What is IRAP and does it follow the same advance payment schedule as IRES?
IRAP (Imposta Regionale sulle Attività Produttive) is Italy's regional production tax, calculated on net production value (gross margin net of most labor costs) at a standard rate of 3.9%. IRAP follows the identical advance payment schedule as IRES: 40% of prior-year IRAP by June 30 (extendable to July 31 with 0.40% surcharge), and 60% by November 30. IRAP applies even in years when the company reports a net accounting loss, provided the gross margin is positive — a point that consistently surprises foreign founders. First-year SRLs generally owe no IRAP acconti for the same reason they owe no IRES acconti.
Q: What interest rate applies to Italian tax late payments in 2024?
The legal interest rate for Italian tax purposes is set annually by MEF decree. For 2024, the rate is 5% per annum. This rate applies to all late payment interest calculations — both under ravvedimento operoso self-corrections and in Agenzia delle Entrate formal assessments. The 5% rate is significantly higher than previous years (it was 1% in 2022 and 5% from January 2024). The accumulating interest compound effect means that even a modest tax underpayment left uncorrected for two or more years carries a meaningful additional cost beyond the principal penalty.
Q: What is the Concordato Preventivo Biennale (CPB) and is my SRL eligible?
The CPB (D.Lgs. 13/2024) allows eligible taxpayers to agree a fixed taxable income with Agenzia delle Entrate for two years, eliminating acconto uncertainty and reducing audit risk during the agreed period. Eligibility is limited to taxpayers subject to ISA (Indici Sintetici di Affidabilità Fiscale — Italy's synthetic reliability scoring for small businesses) and Regime Forfettario holders. Most corporate SRLs outside the ISA regime are not eligible. The 2024–2025 cycle opt-in deadline was October 31, 2024. Watch for the 2026–2027 cycle announcement — it will follow similar timing.
How We Can Help
Italy's advance tax payment system — 40% in June, 60% in November — is straightforward once mapped. But missing a deadline is costly: 25% penalty under the reformed D.Lgs. 87/2024 rules plus 5% annual interest. Self-correction via ravvedimento operoso is dramatically cheaper but requires action within days, with the correct codice tributo values, before the tax authority acts.
