Answers to the common questions. If yours is not here, email dylan@dragondevelopment.co.uk and I will get back to you.

Restore purchases

Bought Pro and moved to a new phone, or reinstalled the app?

  1. Make sure you are signed in to the same Apple ID or Google account you used to buy Pro.
  2. Open Sole Sums and tap the More tab.
  3. Under Settings, tap Restore purchases. It is also on the Pro screen.

Pro unlocks again at no extra cost. It is a one-off purchase, not a subscription.

Export your records

With Pro, you can export your income and expense records and your estimate.

  • CSV for a spreadsheet or your accountant.
  • PDF for a clean summary you can keep or print.

Open the Records tab, scroll to Export, tap CSV or PDF summary, then save or share the file. Exports are created on your device.

Delete your data

Your records live only on your device, so deleting them is in your hands:

  • In the app, open the More tab and tap Delete all data at the bottom. This cannot be undone.
  • Or uninstall the app, which removes its data from your phone.
  • On the web app, use Delete all data on the More tab, or clear your browser's site data for solesums.impactlayer.workers.dev.

Export a CSV first if you want to keep a copy.

Refunds

Purchases go through Apple or Google, so refunds do too. Request one through the App Store (reportaproblem.apple.com) or Google Play (your order history).

Common questions

Why is my January bill bigger than my tax?

Probably the first payment on account. See payments on account explained.

Does the app file my return?

No. File through your HMRC online account or HMRC-recognised software. Sole Sums helps you get the figures ready.

What does it not cover?

Dividends, savings interest over your allowance, property income, capital gains, pension tax relief and the High Income Child Benefit Charge. If any of these apply, your real bill will be different.

Which rates does it use?

GOV.UK rates for 2025/26 and 2026/27, last checked on 3 November 2026. See the rates guide.

Does it work offline?

Yes. No account and no internet connection needed once it is installed.

I think a figure is wrong

Please email me with the tax year, region and the figures you entered. I check every report against GOV.UK.
