Deadlines, extensions & installments
| Item | When due | Notes |
|---|---|---|
| Inheritance tax return (déclaration de succession) | 6 months after date of death | File with the competent Vaud office based on the decedent’s last residence or Vaud-situs property. |
| Extension to file | On written request before the deadline | Provide reasons (e.g., pending appraisals). Extension to file does not extend time to pay once assessed. |
| Payment of tax | As stated on the assessment notice | ACI typically sets a payment deadline (often ~30 days). Interest on arrears accrues after the due date. |
| Provisional payments | Any time before assessment | Heirs may make on-account payments to reduce interest exposure; reference the estate file number if available. |
How to file & pay
Submission
Inheritance returns are usually filed on paper (or per ACI instruction) with the Administration cantonale des impôts and, where relevant, the commune. Some correspondence may be handled electronically if agreed. Always follow the address and instructions on your notice.
Payment, penalties & interest
- Payment: by the deadline stated on the assessment (commonly ~30 days).
- Interest on arrears: accrues after the due date on unpaid amounts.
- Administrative fines: possible for late filing, under-reporting, or non-disclosure.
Sanctions are applied case-by-case under cantonal rules.
Practical checklists
Before filing
- Confirm domicile and identify Vaud-situs assets (for nonresidents).
- Collect valuations and statements as of the date of death.
- Compile the heirs list and relationship proofs for exemptions.
- Request land-registry extracts (Registre foncier) for Vaud real estate where needed.
When extending
- Submit a written extension request before the 6-month deadline with reason and estimated timeline.
- Consider a provisional payment to limit interest.
- Track payments so they can be credited on assessment.
FAQs
When is the Vaud inheritance tax return due?
Generally within six months after the date of death. The authority may grant more time on written request, but payment remains due by the date shown on the assessment, and interest applies to late payment.
How do I get more time to file?
Apply in writing to ACI before the deadline. Explain the reason (e.g., pending appraisals). An approved filing extension does not extend time to pay.
Where do I get the forms?
Forms are provided by the Administration cantonale des impôts. Contact details appear on your notice; general information is available at vd.ch.
What must be attached?
Death certificate, civil-status/family register extract, will or inheritance contract, appraisals, bank and portfolio statements, real property valuations, and relationship proofs to claim exemptions or reduced rates.
