Pros and cons

Pros:

One of the most experienced MTD providers, first recognised for end-to-end MTD filing back in 2020
Mobile-first design suits sole traders who want to manage tax on the go rather than at a desktop
Useful for people with mixed income sources, such as self-employment plus employment or property
Roots in tax relief tracking may help you spot deductions you’d otherwise miss

Cons:

The free Lite tier does not cover MTD for Income Tax submission - you need the paid Pro plan at £9.99 a month for that
Less well-known than major accounting platforms, so fewer independent reviews and less accountant familiarity than the big names
Mobile-first focus means it may lack the deeper bookkeeping features (invoicing, detailed reporting) of full accounting software

Who is Untied best for MTD for Income Tax?

Untied is worth a look if you want a simple, mobile-first way to manage your tax affairs from one of the most established names specifically in MTD, particularly if you have mixed income from employment, self-employment or property. Just be clear going in that the free Lite tier won’t cover your MTD for Income Tax submission - you’ll need the £9.99-a-month Pro plan for that. Once you factor in that cost, it’s worth comparing against other HMRC-recognised options.
