Frequently asked questions
Does Tier 1 apply to business kilometres only?
IRD says Tier 1 applies to the first 14,000 total kilometres travelled by the vehicle, including business and non-business use. The claim is then based on the business-use portion.
Do I still need records?
Yes. Keep records that support your business-use percentage or business kilometres, such as a logbook or other reliable evidence.
