Tax demands don't last forever: prescription in Italian tax law
Many Italians assume that a tax demand from the Revenue Agency must always be paid regardless of when it was issued. This assumption is wrong. Italian tax law provides for prescription periods after which the right to collect the debt expires — even if the demand has been formally issued.
Prescription periods by type of tax
The applicable prescription period depends on the underlying tax:
- Car registration tax (bollo auto): 3 years from the year it was due
- Local taxes (IMU, TARI, etc.): 5 years
- Income tax (IRPEF) and VAT: 10 years from the date of the definitive assessment
- Social security contributions (INPS): 5 years
The prescription runs from the date the tax became due — not from when the demand was issued. A demand for 2018 car tax received in 2024 could already be time-barred.
Interruption of prescription
Prescription can be interrupted by formal acts of the Revenue Agency: notification of a demand, enforcement notice or attachment order. Each interruption starts the prescription clock running again from zero. This is why it is essential to check whether there have been any interrupting acts before concluding a demand is time-barred.
What to do when a demand arrives
Do not panic and do not pay automatically. Check:
- The date the underlying tax was due
- The type of tax (to determine the applicable prescription period)
- Whether any interrupting acts were formally notified to you
If you believe the demand may be time-barred, consult a tax professional or a patronato (free advice centre) before doing anything else. Paying a time-barred demand means waiving the defence.
