Does JoltMile file my tax return for me?
No. It keeps the records, works out the figures and exports them. You or your accountant file with HMRC.
Last checked 12/09/2026.
No. JoltMile is the record-keeping and calculation half, not the filing half.
What it does: logs every shift and expense, applies the mileage rates at the right point in the year, estimates what you will owe as you go, and produces a Self Assessment summary with the figures laid out the way the return asks for them.
What it does not do: submit anything to HMRC. You file through your HMRC online account, or hand the export to an accountant.
That is a deliberate line. Filing software has to be recognised by HMRC and carries obligations of its own, and being honest about where the boundary sits is better than a driver discovering it in the last week of January.
