Tax payment notices (cartella) and tax assessment notices are the two main instruments issued by the tax authorities, but their nature, effects and available defence options differ significantly. Confusing them is one of the most common mistakes taxpayers make and can lead to inadmissible appeals.
Tax assessment notice: what it is
A tax assessment notice is the instrument by which the Italian Revenue Agency (Agenzia delle Entrate) determines that more tax is due than the taxpayer has declared. It is the first instrument asserting the tax claim: it contains the reasons (why the authorities consider additional tax to be due), the amount (tax + penalties + interest) and details of the body before which it may be challenged.
- Who issues it: the Italian Revenue Agency (Agenzia delle Entrate), the Customs Agency, municipalities (for IMU and TARI), regions (for IRAP).
- When it is received: following a tax audit, a tax audit report (PVC), a formal check or an automated check.
- Time limit for appeal: 60 days from service.
- Enforceability: since 1 October 2011, tax assessment notices have been "enforceable": after 60 days, they constitute an enforceable instrument for compulsory collection without the need for a tax payment notice (cartella).
Tax payment notice (cartella): what it is
A tax payment notice (cartella) is a collection instrument: it does not constitute a new claim, but collects a debt already assessed by the taxing authority and entered on the collection roll. It is issued by the Italian Tax Collection Agency (ADER) on behalf of the creditor authority.
- Who issues it: the Italian Tax Collection Agency (ADER), formerly Equitalia.
- Underlying instrument: the collection roll drawn up by the creditor authority (the Italian Revenue Agency (Agenzia delle Entrate), a municipality, INPS (Italian social security institute), etc.).
- Time limit for appeal: 60 days from service.
- Effects: it allows ADER to impose an administrative vehicle restriction, register a mortgage or carry out an attachment.

Which notice to challenge
The fundamental rule is: challenge the most recently served instrument, raising defects in the underlying instruments if they were not served.
- If you receive a tax assessment notice: you challenge the merits of the claim (whether the additional tax is justified).
- If you receive a tax payment notice (cartella) preceded by a duly served tax assessment notice: you may challenge only defects in the tax payment notice (cartella) itself (service, subsequent expiry of the limitation period, calculation errors). You can no longer challenge the merits.
- If you receive a tax payment notice (cartella) without ever having been served with the tax assessment notice: you may also challenge the merits of the claim, raising the failure to serve the underlying instrument (Italian Supreme Court (Corte di Cassazione), Joint Divisions (Sezioni Unite), 16412/2007).
Specific options for avoiding litigation
For a tax assessment notice
- Tax settlement procedure (accertamento con adesione) (D.Lgs. 218/1997): involves requesting discussions with the tax authority within 60 days; suspends the time limit for appeal for 90 days; allows penalties to be reduced to 1/3.
- Acceptance of the assessment: payment within 60 days with penalties reduced to 1/3.
- Self-correction request (autotutela): an application to the authority that issued the instrument.
For a tax payment notice (cartella)
- Statutory suspension under L. 228/2012: on one of the 7 exhaustively specified grounds.
- Self-correction request (autotutela): submitted to the creditor authority (not ADER).
- Payment by instalments: up to 120 instalments from 1 January 2025.
Frequently Asked Questions
Can I challenge a tax payment notice (cartella) and a tax assessment notice together?
Yes, if the tax payment notice (cartella) is the first instrument through which you become aware of the unserved tax assessment notice. The combined appeal must be filed within 60 days of service of the tax payment notice (cartella).
What happens if I ignore a tax assessment notice?
After 60 days, the assessment becomes final and the Italian Tax Collection Agency (ADER) may proceed directly with an administrative vehicle restriction, mortgage or attachment without having to issue a tax payment notice (cartella).
Does an enforceable tax assessment notice remove the need for a tax payment notice (cartella)?
Yes. For taxes assessed from 1 October 2011 (the reform under D.L. 78/2010), the tax assessment notice is an enforceable instrument in its own right: issuing a tax payment notice (cartella) is no longer necessary. Local taxes, social security contributions and other debts, however, remain subject to a tax payment notice (cartella).
