About us
Built for landlords and the self-employed facing Making Tax Digital
Quarterwise is UK-built software that turns the new quarterly tax rules into a few minutes of record keeping and an update you can send in seconds.

Making Tax Digital for Income Tax asks landlords and the self-employed to keep digital records, send HMRC four quarterly updates a year and then a tax return. Quarterwise is the software that does it with you: you record money as it comes in and goes out, and when an update is due, the figures are already there to check and send.
What we offer
Quarterly updates and the tax return. Quarterwise works out each cumulative update from your records and sends it straight to HMRC, then does the year end: adjustments and allowances, HMRC's tax calculation and the return itself. Standard and calendar quarters are both supported.
Records that stay light. Add entries by hand, bring in a spreadsheet or your Airbnb, Vrbo or Booking.com earnings files, and on Pro let AI suggest the HMRC category and keep your receipts with each entry.
Property. UK and overseas property, each kept as the separate business HMRC treats it as. Jointly owned property can be shared with your co-owner, and each of you files your own share. Pro adds a profit and loss for every property.
Self-employment. Income and expenses in HMRC's self-employment categories, invoices sent as PDFs, and Construction Industry Scheme deductions tracked so they count towards your tax bill.
The rest of your tax return. Interest, dividends, employment and pensions, Gift Aid, capital gains and the other income and reliefs a return needs, so the year end can be done in one place.
Room for your accountant. Invite an adviser to view your books or keep them for you. Only you can connect to HMRC or send an update.
Free guides and tools. Our guides explain the rules, deadlines and penalties, and the free calculators answer questions like whether MTD applies to you yet. No sign-up needed.
Free filing, with no time limit
The free plan covers one property or one self-employment business, with full filing of quarterly updates and the tax return. There is no card to enter and no trial that runs out. Pro, at £12 a month or £99 a year, is for more properties or businesses and the extra features. See pricing for the detail.
Our mission
Most people affected by Making Tax Digital have never thought of themselves as running accounts. They let a flat, or they work for themselves, and until now they did one tax return a year. We want the new rules to take them a few minutes at a time, without an accountant's fee they didn't need before, and to leave them confident that what reached HMRC was right.
That shapes how we build. The app checks its figures against what HMRC holds and tells you plainly when something doesn't match. It says what each step means before you take it. We read every email to support, and customers shape what we build next.
Recognised by HMRC
HMRC has granted Quarterwise the “MTD ready – recognised by HMRC” trademark, reference C2V6MT. Quarterwise files through HMRC's official Making Tax Digital APIs and is listed in HMRC's software finder on GOV.UK.
