Multiple breaches, the notice of charge and settling at a discount

Marta owns a limited company in Parma and receives two notices for consecutive years: the understatement penalty is 7,000 € in the first and 4,200 € in the second. Added up, that is 11,200 €. Under the rules on multiple breaches, a single combined penalty can never exceed that sum; and by paying within the appeal deadline she can settle for one third. The final bill depends on how the rules interlock.

When there is more than one breach

People who get something wrong rarely do it only once. A non-deductible cost recurs every year; a wrong VAT rate spreads across dozens of invoices. Adding every penalty one by one would often give absurd totals. Article 12 of Decree 472 therefore provides a single-penalty mechanism, generally known as cumulo giuridico.

Three situations trigger it. Formal concurrence: a single act or omission breaches several provisions, possibly for different taxes. Material concurrence: several acts breach the same provision repeatedly. Continuation: several breaches, even at different times, committed progressively or under one plan, undermine the calculation of the tax base or the settlement of the tax.

The basic rule is simple: take the penalty due for the most serious breach and raise it by between one quarter and double. Where to land within that range follows the article 7 criteria of seriousness, conduct and personality. One error repeated through carelessness sits near the bottom; a sustained scheme, near the top.

Some examples help. Unbilled revenue that cuts both the VAT and part of the declared income is formal concurrence: one omission, several rules broken. Ten invoices issued late in the same year are material concurrence. A run of fictitious costs booked month after month to shrink the tax base is continuation.

The 2024 exclusions: payments and offsets

The reform took two families of breach out of the mechanism: those concerning payment obligations and those concerning undue offsetting of credits. Material concurrence and continuation, the text now says, do not apply to them. Each missed payment remains a separate breach with its own penalty.

There is a logic to it. For payments, the penalty is proportional to the tax left unpaid, and the natural remedy is voluntary correction, which lowers the penalty according to how quickly the taxpayer acts. Three forgotten F24 payments do not become one breach: each is put right separately, as the course on ravvedimento operoso explains.

Several taxes, several years: the step-ups

When linked breaches involve several taxes, for example corporate income tax and VAT, the quarter-to-double increase is not applied to the most serious penalty as it stands, but to that penalty stepped up by one fifth. The law thereby treats hitting two taxes as worse than hitting one.

When the breaches fall in different tax years, the step-up is steeper: the most serious penalty is raised by between one half and three times, and the quarter-to-double increase is then applied to the result. Where several taxes and several years combine, the half-to-triple step-up works on the penalty already raised by one fifth.

The table below sums up the four cases. Read it from left to right: first identify the most serious penalty at stake, then apply the step-ups in the middle column, and finally the quarter-to-double increase. Each stage is a range: the office picks a point within it and must give its reasons.

The ceiling: never above the sum

The single-penalty mechanism exists to help the taxpayer, and paragraph 7 guarantees it. In the article 12 cases, the penalty must respect proportionality and can never exceed what would result from adding up the penalties for the individual breaches. If the step-ups overshoot the sum, the sum is what applies.

This happens more often than one might think. With just two breaches in two years, the most serious penalty raised by half and then by a quarter frequently exceeds the sum of the two. The ceiling then becomes the real amount, and it is always worth checking before accepting the single penalty the office proposes.

In practice, redo the sum in two columns. In the first, compute the single penalty with the minimum step-ups; in the second, add up the individual penalties. Take whichever is lower, and weigh settlement from there. Two lines in a spreadsheet can be worth thousands of euro.

Concurrence and continuation are broken off once the breach is formally established. What is done after that point, for example after an inspection report, no longer merges with the breach already recorded. And if the office charges breaches in successive notices, it must recalculate the overall penalty taking account of those covered by the earlier measure.

The mechanism also stops at the boundaries between authorities. The rules apply separately to state taxes and to the taxes of each other levying body, such as a municipality; within state taxes, customs duties and excise duties are kept apart. An error touching both corporate tax and IMU produces two separate penalties, not one.

One last exception concerns the settlement tools. In agreed assessments, court settlements and voluntary correction, the single penalty is worked out separately for each tax, each tax year and each procedure. The step-ups for several taxes and several years do not apply in those cases.

The notice of charge and the three routes

Where the penalty does not come with an assessment notice, the office follows article 16 and serves a notice of charge, the atto di contestazione. On pain of nullity it must state the facts alleged, the evidence, the rules applied, the criteria used to set the penalties and their size, and the statutory minimum and maximum for each breach.

If the reasoning refers to another document the taxpayer has neither received nor seen, that document must be attached, unless its essential content is reproduced. This is the first thing to check: a notice pointing to an inspection report never handed over, without summarising it, exposes the office to a defect that an appeal can exploit.

• the facts attributed to the offender and the supporting evidence
• the rules applied to each breach
• the criteria used to set the penalties and their amount
• the statutory minimum and maximum amounts
• the invitation to pay with the settlement benefits, and the body to appeal to

The notice also asks the taxpayer to choose. The first route is settlement at a discount: within the appeal deadline, pay one third of the penalty stated, and in any case no less than one third of the statutory minimums for the most serious breaches of each tax. Settlement also bars any ancillary penalties.

Payment can be spread out: up to eight equal quarterly instalments, or up to sixteen if the amount due exceeds 50,000 euro. The first instalment is due within the appeal deadline, the others by the last day of each quarter, with interest running from the day after the first instalment is paid.

The second route is a defence brief, filed within the same deadline. The office then has one year to impose penalties by a measure that also gives reasons on the points raised. If the penalties are reduced after the brief is accepted, the new amount can also be settled at one third.

The third route is an appeal. With neither settlement nor a defence brief, the notice of charge counts as the measure imposing the penalty and is challenged before the tax court. An appeal lodged straight away, however, lapses if a defence brief is filed at the same time: the two routes cannot be taken together.

Choosing calls for an honest calculation. If the claim is sound, settling at one third is almost always cheapest and avoids ancillary penalties. If it is partly unfounded, a defence brief may lower the penalty and still leaves settlement open afterwards. An appeal makes sense when the facts alleged are wrong at the root.

Immediate imposition with the assessment notice

More often the penalty arrives together with the tax. Article 17 allows penalties linked to the tax to be imposed without a prior notice of charge, in a measure issued alongside the assessment or adjustment notice and reasoned on pain of nullity. Here too, settlement at one third of the penalty imposed is available within the appeal deadline.

There is one important exception. Penalties for failed or late payment, even when they arise from automated and formal checks of returns, can be entered on the collection roll without any notice of charge, and settlement at one third never applies to them. Those who fail to pay have voluntary correction, not settlement.

These rules were read in the text of Decree 472 published in the Gazzetta Ufficiale in September 2026, in its last version before repeal. The Gazzetta marks the articles as repealed by Legislative Decree 173 of 2024, the consolidated text on tax penalties, as amended by Decree-Law 200 of 2025: for future breaches, check the consolidated text.
