FBT Key Dates
The FBT year runs 1 April to 31 March — out of sync with the financial year, which is exactly why its deadlines get missed.
| Date | What |
|---|---|
| 31 March | FBT year ends — measure car odometers, log books, benefit records |
| 21 May | FBT return and payment due if you lodge yourself. Also the deadline to be added to a tax agent's FBT client list for the later date |
| 25 June | Typical due date when lodging electronically through a tax agent |
If you provide cars, car parking, entertainment, loans or expense reimbursements to employees (including directors), you may have an FBT obligation even if no FBT is payable — many employers lodge a nil return or keep records proving no liability. Talk to your adviser before 21 May.
