Keepr vs untied for Making Tax Digital
By the selector's own rules, Keepr and untied both work for sole traders, so the choice comes down to the six points where they differ. untied offers support for more than one property, support for jointly owned property, bank feeds and phone apps, which Keepr does not. untied does not offer a free plan, which Keepr does. Their cheapest plans are listed as free for Keepr and £129.99 a year including VAT, about £10.83 a month (Pro including MTD) for untied.
Keepr suits sole traders and freelancers with no rental income who want MTD filing at no cost, people who bill by the hour and want time tracking and invoicing next to their tax records and sole traders whose accountant would like their own login. untied suits people with mixed income (property + self-employment or PAYE), sole traders who want a phone-only workflow and non-resident and joint-owner landlords with complex returns.
The facts on this page come from each provider’s own pages and from HMRC’s software list, and how we compare products explains how we check them.
If you are thinking of moving from one to the other, the guide to changing your MTD software explains what GOV.UK says about when you can move and what happens to your records.
Where they differ
These are the points where our checks of the two products came out differently. A “No” means we did not find that feature on the provider’s own pages when we last checked them. Where we had nothing to go on for one of the two, we leave the point out here rather than guess.
| Point | Keepr | untied |
|---|---|---|
| Cheapest plan | Free | £129.99 a year including VAT, about £10.83 a month (Pro including MTD) |
| Free plan | Yes | No |
| More than one property | No | Yes |
| Jointly owned property | No | Yes |
| Bank feeds | No | Yes |
| Phone apps | No | Yes (iOS and Android) |
On the other points we compare (holiday lets and former FHL, self-employment income, receipt capture, accountant access and MTD for VAT returns), they give the same answer, or at least one provider does not say. The full list is under each product’s own page.
What HMRC’s software list says about both
HMRC’s list marks each feature as available now or intended for later. This is what HMRC’s list says, not something we have tested ourselves. Where HMRC lists a product under more than one name, we show the strongest answer and the listing it comes from.

The cheapest plan for your situation
A product’s cheapest plan is not always one you can use, because some plans are only for landlords or only for sole traders. These are the lowest prices the selector would show each reader, as each provider states them. Where a price grows with the number of properties, it is shown as a starting price. The figure over 12 months is the same plan at its regular price, worked out the way the software cost calculator does it.

Notes from our checks
Keepr
Keepr's MTD page says it covers sole trader self-employment income from start to finish, including digital records, all four quarterly updates and the final declaration, and that it has been on GOV.UK's software list since 28 August 2026. The same page lists UK property income, Scottish rates, the Construction Industry Scheme, foreign income, pension income, capital gains, the High Income Child Benefit Charge and partnership income as not supported, and employment income, UK interest, dividends and some reliefs as in development by April 2027. If your final declaration needs any of those you would need other software alongside Keepr, and landlords need different software for their property income, so we mark both plans as unsuitable when property income is in the picture. Keepr says MTD works the same on the free plan as on Pro, and gives Pro's annual price as £84. We did not find a bank feed, mobile apps or anything about furnished holiday lets. We checked this on 25 October 2026.
untied
untied is often listed as free in roundups, but the free version is a 30-day trial and filing requires a paid plan. Plans are priced per tax year with VAT included, which is unusual for this market, so compare like-for-like against ex-VAT monthly prices carefully. untied also sells a cheaper Lite plan, but its pricing page shows Making Tax Digital and property income as not included on Lite, so we do not list it.
Neither product is ranked above the other here: the page sets out what each provider says so you can weigh it against your own situation. How we compare products
