A job or other income now counts in your tax estimate

Add a job, rent or another trade, with the tax already taken off your payslips, and the estimate covers your whole year rather than the driving alone.

Most drivers on JoltMile are not only driving. Until now the tax estimate could only see the driving, which meant a driver with a job was given a figure for part of their year and left to work out the rest themselves. That is fixed.

Adding it

Open Expenses on the website, or the Money tab in the app, and pick Other income. Add a source, such as a job, a room you rent out or another trade you run, then add each payment against it.

For a job, enter the pay before tax and the tax taken off that payslip. PAYE works on the whole year so far, so a lighter month can hand tax back instead of taking it, and there is a Refunded option for those.

What it changes

  • The tax estimate works out income tax on everything together, the way HMRC does. A job uses your personal allowance first, so more of the driving profit is taxable and the estimate says so.
  • Class 4 National Insurance is still charged on the trading profit alone, because wages do not attract it.
  • The tax your employer already took comes off at the end. If more was taken than the whole year works out at, the estimate goes below zero, which means HMRC owes you.
  • The personal allowance ring on your dashboard counts the other income too, since one allowance covers everything a person earns.
  • Self Assessment gains the lines for the whole position: the tax on all your income, the PAYE credit, and what is left to pay or coming back.

Leave the personal allowance switched on in Settings once you have added a job. The wages already use it, and switching it off as well would take it away twice.

Seeing it beside the driving

Earnings still opens on your driving, because that is what JoltMile is for. The menu at the top right now offers All Earnings, which adds the other income into gross, take-home and current balance, and a view for each source on its own. Your hourly rates never include it: they are about the driving, and a salary paid for hours the app knows nothing about would make them meaningless.
