QuickBooks (Sole Trader Plus / Simple Start) vs untied for Making Tax Digital
By the selector's own rules, QuickBooks (Sole Trader Plus / Simple Start) and untied both work for landlords and sole traders, so the choice comes down to the four points where they differ. untied offers support for more than one property and support for jointly owned property, which QuickBooks (Sole Trader Plus / Simple Start) does not. untied does not offer MTD for VAT returns, which QuickBooks (Sole Trader Plus / Simple Start) does. Their cheapest plans are listed as £10 plus VAT a month (Sole Trader Plus) for QuickBooks (Sole Trader Plus / Simple Start) and £129.99 a year including VAT, about £10.83 a month (Pro including MTD) for untied.
QuickBooks (Sole Trader Plus / Simple Start) suits sole traders or single-property landlords, landlords who want a lower-priced mainstream option and people who do most of their bookkeeping on a phone. 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 | QuickBooks (Sole Trader Plus / Simple Start) | untied |
|---|---|---|
| Cheapest plan | £10 plus VAT a month (Sole Trader Plus) | £129.99 a year including VAT, about £10.83 a month (Pro including MTD) |
| More than one property | No | Yes |
| Jointly owned property | No | Yes |
| MTD for VAT returns | Yes, from the Simple Start plan | No |
On the other points we compare (free plan, holiday lets and former FHL, self-employment income, bank feeds, receipt capture, phone apps and accountant access), they give the same answer, or at least one provider does not say. The full list is under each product’s own page.
If you are registered for VAT, the guide to one product for MTD for VAT and Income Tax explains what GOV.UK asks you to check and which of the products we compare say they handle both.

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
QuickBooks (Sole Trader Plus / Simple Start)
Regular monthly prices are shown excluding VAT. When we checked the pricing page on 3 November 2026, the price list it loads showed Intuit's offer of 90% off for six months for new customers, running until 20 November 2026, so the pricing page is the place to see any offer running now. Its setup guidance requires a separate account for each business or property income source. Combined subscription costs were not confirmed, so the selector does not recommend QuickBooks for mixed income. Joint-property support also remains unconfirmed.
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
