Mobile phone, internet and vehicle allowances

Set up these allowances under Income Tax > Tax Allowances.

Mobile phone - typically 50% if you use the same phone for business and personal calls. Click Mobile Phone, set the percentage, save. Code mobile bills under Private use expenses > Mobile phone.

Internet - typically 50% for shared use. Set the percentage in the same Tax Allowances page. Code internet bills under Private use expenses > Internet.

Vehicle - the business percentage is based on a logbook (90-day record of business vs personal trips). Set it in Tax Allowances. Code vehicle costs (fuel, servicing, insurance, repairs) under the relevant vehicle category and the percentage applies.

If you change vehicle, work setup, or your business use changes, update the percentage in the same place.
