Which UK tax apps are HMRC-recognised?

Pie is HMRC-recognised and Making Tax Digital-approved for direct Self Assessment submission. Coconut supports MTD filing on its higher tier. Check recognition before paying, since a tool that cannot submit directly leaves you re-keying into HMRC's portal.

Is it better to use an accountant or an app for Self Assessment?

It depends on which failure you are avoiding. An accountant-backed service like TaxScouts removes the work and the judgment calls for a fixed fee. An app like Pie or Coconut costs less and gives continuous visibility, but you remain responsible for the positions taken.

What does Making Tax Digital mean for freelancers?

MTD requires digital record-keeping and submission through approved software rather than manual entry into HMRC's portal. Practically, it means your chosen tool needs MTD approval to be useful over the long run.

Can UK freelancers get tax deducted automatically like PAYE?

Effectively yes, through Hnry. Payments pass through its account, tax obligations are calculated and deducted at the moment of payment, and returns are filed when due — the closest thing to PAYE available to the self-employed.

Comparison

The best AI tax software for UK freelancers and Self Assessment

HMRC recognition, Making Tax Digital readiness, and whether you want software or an accountant attached.

Independent analysis · Figures verified August 2026 · Methodology

UK Self Assessment splits neatly into two buyer types. Some people want the return taken off their hands entirely; others want to know, continuously, what they owe so that January holds no surprises. The UK market has separate products for each, and picking the wrong type is the most common mistake.

There is a hard constraint worth checking first: HMRC recognition and Making Tax Digital approval. A tool that cannot submit directly leaves you re-keying figures into HMRC's portal, which defeats the purpose.

If you want it handled: TaxScouts

TaxScouts pairs a software intake with a network of 150+ accredited UK accountants who complete and file the return for a fixed fee, typically within about 48 hours. The automation is in matching and document collection; a human does the filing and carries the professional judgment.

Its 4.8 Trustpilot rating across 6,357 reviews is the strongest review record of any UK product in this directory, with speed and professionalism the recurring themes. Founded in London in 2017, it was acquired by Berlin's Taxfix Group in July 2024 and is being rebranded as Taxfix in the UK — the service continues unchanged.

If you want live visibility: Pie and Coconut

Pie connects your financial accounts and maintains a real-time Self Assessment estimate that updates as you earn, alongside bookkeeping and receipt organisation. It is HMRC-recognised and Making Tax Digital-approved for direct submission, and was named Best Tax App & Self Assessment Software in UK industry coverage for 2025. It holds 4.0 on Trustpilot, though across only 109 reviews.

Coconut takes the same live-estimate approach but categorises transactions specifically against HMRC's SA103 self-employment and SA105 property schedules as they import — useful if you are a landlord or CIS subcontractor as well as a sole trader. It holds 4.0 on Trustpilot across 776 reviews and is now part of the GoSimpleTax family, with plans from £99.99/year up to £159.99 for MTD filing plus Self Assessment.

The option most UK freelancers overlook

Hnry, the New Zealand company that automates sole-trader tax by deducting and remitting obligations from each payment as it arrives, now operates in the UK as well as New Zealand and Australia. It holds 4.7 on Trustpilot across 681 reviews.

The model is structurally different from everything else here: rather than estimating what you will owe and reconciling later, nothing ever accumulates unpaid. If January bills are the specific thing you want to eliminate, that mechanism addresses it directly.
