Bring your records from another app

Moving to Kev from QuickBooks Self-Employed, MileIQ or Driversnote? You don't have to start the tax year again. Export your trips or expenses as a CSV file and Kev brings them in. It's free on every plan.

1. Get the file out of your old app

• QuickBooks Self-Employed: open Trips (or Transactions), pick the dates and look for Export. Save the CSV file.
• MileIQ: sign in on the MileIQ website, make a report of your drives for the dates you want and download it as CSV.
• Driversnote: sign in on the Driversnote website, open your trips or reports, pick the dates and export them as CSV or Excel.
• A spreadsheet: any CSV file works if each row has a date and a distance (journeys) or a date and an amount (expenses). There's a Kev template to fill in if you'd like one.

Got an Excel file (.xlsx)? Open it and save or export it as CSV first.

Export one tax year at a time if your file is big: Kev takes up to 5,000 rows at once.

2. Import it

1. Open Settings, then Your data, then Import a file. (Or tap Moving from another app? on the Mileage screen.)
2. Pick Journeys or Expenses, and where the file came from.
3. Tap Choose the CSV file and pick it.
4. Kev matches the columns for you. If one looks wrong, tap Change columns and pick the right one. Check the dates are read the right way round (day first, like 31/01/2026, or month first, like 01/31/2026), and for journeys whether distances are in miles or kilometres.
5. Check the preview. Kev shows how many it will bring in, the first few, and what it's leaving out and why.
6. For journeys, pick the vehicle they were in. On the free plan that's your current vehicle.
7. Tap Import.

What comes across

Journeys

• Only business journeys. If the file says whether each trip was business or personal, personal ones and trips you never sorted are left out.
• Journeys from 6 April 2025 onwards, the tax years Kev has HMRC rates for.
• Each claim is worked out at the HMRC rate for its tax year, and switches to the lower rate at the right point after 10,000 miles, counting the journeys you already had in Kev. If your vehicle uses your own rate per mile, Kev uses that.
• Imported journeys have the date, places, miles and reason from your file, but no times. They show up in your mileage history and reports like any other journey.

Expenses

• Spending only. If the file has money in as well (plus amounts next to minus ones, or a type such as Income), that's left out, and so is anything marked personal.
• Kev picks the nearest of its own categories from your old app's category or the description. Check them in Expenses afterwards.
• They're saved as confirmed, with no receipt photo. You can add one later.

Nothing twice, and you can undo it

Anything already in Kev is skipped, so importing the same file twice won't double up. To take an import back out, open Settings, Your data, Import a file and tap Undo next to it under Your imports. Kev removes everything that file added and works out your mileage claims again without it.

Keep your old records

Keep the downloads and receipts from your old app as well. HMRC says to keep your records for at least 5 years after the 31 January deadline for the tax year they're for.
