How to register, update, and close TARI
Register when you move in. File the TARI start declaration within the deadline on your Comune’s website (often 30 days). Attach your lease or deed, meter photos, and your codice fiscale. Keep the protocol number.
Update when your household changes. Births, students living away, or a change in occupants can affect the bill. Submit an update with proof (e.g., university residence or rental contract for the student).
Close when you move out. File a TARI stop with the end date, add final meter photos and proof of handover. This prevents charges after you leave.
Sorting rules and service quality. Your Comune’s environmental office publishes calendars and guides. For national consumer guidance on urban waste service standards, see the regulator’s page: ARERA — Rifiuti urbani.
How to calculate and pay TARI
Calculation. Most Comuni apply a fixed part (service) and a variable part (occupants). Discounts may apply to single-person households, new parents, students, or long absences. Read your Comune’s TARI regulation each year.
Payment methods. Expect a payment slip or PagoPA notice. You can pay online on your municipal portal, via banking apps, or at the post office. Keep the receipt PDF with the year in the file name. If you prefer the counter route, our primer How to Pay Bills and Taxes at the Italian Post Office shows each step.
IMU: check rates, deadlines, and exemptions
Who pays. Owners of second homes and specific categories of primary residences defined by law and local resolutions.
Deadlines. Two main dates: an advance in June and a balance in December. Mark both in your calendar with reminders seven and two days before.
Rates and deductions. Each Comune publishes an annual IMU resolution with aliquots and deductions. Use the Finance Ministry hub to locate your municipality’s tax page: finanze.gov.it. If the math gets messy (ownership changes mid-year, different categories, renovated property), a CAF can help; see What Is a “CAF” and How It Can Help You for documents to bring.
How to pay. Use F24, PagoPA, or the channels listed by your Comune. Save the receipt with a consistent naming convention, e.g., IMU_ComuneName_2025_balance.pdf.
Step-by-step: your local-taxes admin stack
1) Map your positions. List each home you occupy or own and note who pays TARI or IMU. Tenants usually pay TARI; owners pay IMU on second homes.
2) Set up digital access. Many Comuni provide online tax areas. Activate SPID to log in and download notices; if you need a refresher, read How to Get a SPID Digital Identity.
3) Centralise documents. Keep a single folder with leases/deeds, registry certificates, past bills, and receipts. Use searchable PDFs and clear names (e.g., TARI_Start_Comune_YYYYMM.pdf).
4) Use certified delivery when needed. If the office asks for a provable notice (start/stop TARI, corrections), send a single PDF via PEC; our guide What Is PEC and Why You Might Need It explains how to get legal delivery receipts.
Common reductions and how to request them
TARI reductions. Single-occupant households, students away from home, families with infants, or long unoccupied periods (documented) may qualify. Check the TARI regulation and file the request with proof within the stated window.
IMU reliefs. Long-term rentals under regulated agreements, historic buildings, properties under renovation, or homes given to family members can receive reduced rates in some cities. Read the annual resolution and file any required declarations.
Moving in and out: avoid double billing
On arrival. Register residency and TARI in the first weeks. Submit square meters, occupants, and start date. Attach the lease or deed.
On departure. Close TARI with the exact end date and meter photos. If you sell, update IMU as of the transfer date in the notary deed. Keep all PDFs for the next cycle to stop automated reminders.
Error handling and late fixes
Wrong data on the bill. Email or PEC the tax office with your protocol number, the page showing the error, and the correct figure with proof (registry extract, updated lease).
Missed IMU deadline. File a ravvedimento operoso as soon as possible to reduce penalties, then set better reminders.
No TARI bill received. Do not wait. Log in to your municipal portal or contact the office; you owe the tax even if the notice did not arrive.
Learn the rules once, then reuse your setup
Two primers make the whole system clearer: National vs. Local Taxes in Italy to see how state and municipal levies split, and How to Pay Bills and Taxes at the Italian Post Office to pay safely at the counter. If forms or calculations feel heavy, book a What Is a “CAF” and How It Can Help You session and bring last year’s bills, your ID, and your tax code. For official rate tables and deadlines, start from finanze.gov.it, and for waste-service standards and consumer rights check ARERA — Rifiuti.
