In Ticino, wealth tax (imposta sulla sostanza) is filed together with the individual income tax return. The canton supports electronic preparation and filing via eTax.ticino PF (individuals) and eTax PG (companies), while paper submission remains possible in defined cases. Cantonal and communal taxes are assessed together on income and net wealth.

Filing Timeline (Typical Cycle)

1. February: The Divisione delle contribuzioni issues filing invitations and makes the current-year eTax.ticino PF / PG software available.
2. Ordinary due date — individuals: The return for income and wealth is usually due by 30 April of the following year.
3. Ordinary due date — companies: Corporate returns are generally due by 30 June.
4. Extension window: Individuals can usually obtain extensions up to 31 December of the filing year; legal entities up to 31 January of the following year, via online request.
5. Assessment & billing: Provisional tax bills may be issued during the year; final assessments follow review of the filed return. Late payments incur interest and reminder fees.

Always rely on the deadline printed in your Ticino filing invitation and confirm current-year rules on the cantonal tax portal before filing.

How to File in Ticino

1) eTax.ticino PF (recommended for individuals)

• Download and install the current-year eTax.ticino PF software from the Divisione delle contribuzioni website.
• Open the file for the relevant year (e.g. eTax.ticino PF 2024) and complete all income schedules plus the 31 December wealth statement (assets, liabilities, allowances).
• Attach supporting documentation (bank and securities statements, real estate valuations, pension summaries, etc.) in the formats accepted by the software.
• Submit your tax return electronically using the integrated transmission function by the deadline indicated in your invitation.
• Save the eTax file and the electronic confirmation for your records.

2) eTax PG for companies

• Corporate taxpayers use eTax PG to complete income and capital tax returns, including wealth-related information for legal entities.
• Calcs and carry-forwards are handled automatically; data can be stored on local drives or network servers.
• Submit returns and attachments electronically in line with the instructions provided for eTax PG.

3) Paper Return (if applicable)

• In specific cases where paper filing is still accepted, use the official forms or print the declaration generated from eTax.ticino.
• Sign the required pages (you and your spouse/partner, if applicable).
• Attach copies of supporting documents; keep originals for your own files.
• Send the full set by post to the address indicated on the filing invitation.

Extensions

If you cannot submit your tax return by the ordinary due date, you must request an extension (proroga). Ticino has shifted to a predominantly **online-only** extension process for individuals.

• Online request (individuals): Scan the QR code on the info flyer enclosed with your tax return or go to the official extension page (e.g. ti.ch/pf-proroga) and identify yourself with your register number and date of birth.
• eTax integration: In many cases, the Richiesta di proroga function is integrated directly in the eTax.ticino software.
• Maximum extension: For individuals, extensions are typically available up to 31 December of the filing year; for companies, up to 31 January of the following year.
• Timing: Submit your extension request before 30 April (individuals) or 30 June (companies) to avoid reminders and discretionary assessments.
• Penalties: Late or missing returns can trigger reminder fees, fines, and discretionary assessments based on estimated income and wealth.

Provisional Payments, Interest & Adjustments

Ticino issues provisional instalments based on prior assessments or estimated income and wealth. If your situation changes materially (e.g. significant income drop, asset sale), you may request an adjustment to these instalments. After filing and review, a final assessment and bill is issued; late payments accrue interest.

• Payment references: Use the QR-bill or payment reference printed on each invoice so payments are correctly allocated.
• Partial payments: Usually allowed; retain payment confirmations and bills for reconciliation with the final assessment.
• Payment difficulties: If you cannot pay in full, contact the tax office promptly to discuss instalment arrangements or relief options.
• Objections (reclamo / Einsprache): If you disagree with the final assessment, file an objection in writing within the deadline indicated on the tax notice.

Nonresidents with Ticino-Situs Assets

Nonresidents owning Ticino real estate or business assets are generally subject to limited tax liability in Ticino and must file a limited Swiss return covering Swiss-situs income and wealth only. A Swiss correspondence address or tax representative is often required. See the Nonresident Guide for more detail.
