Selftax

What Selftax does

Selftax provides online tools for preparing and submitting UK Self Assessment and partnership tax returns. Its step-by-step wizard is designed for people without prior accounting expertise.

The service handles situations such as self-employment, rental, overseas and investment income, company directorship, high income, partnerships, shareholders, CIS and trusts. Partners filing a partnership return also need individual returns.

The company also offers bookkeeping, Excel accounts spreadsheets, an online accounts portal, management reports, statutory accounts and financial forecasts. For MTD, it provides VAT and Income Tax Self Assessment workflows aimed at sole traders and landlords.

Fees and plans

Users can set up an account and work on a return without charge, with payment made when submitting under the site's free-account model. Standard is priced at £12.99 for a single tax return and covers UK individuals, overseas cases, land and property income, company directors, non-residents, landlords, self-employed people, partnerships, shareholders, high earners, CIS and trusts.

Premium is £60 for one tax return and adds consultant checks, completion and HMRC submission. Government Gateway is not mandatory. Professional costs £90 for 10 tax returns and is aimed at accountants, bookkeepers and other professionals filing for clients.

Annual MTD VAT options provide 4 returns for one business at £15, 20 at £36, 40 at £60, 60 at £75, 80 at £80, or 100 at £90. The £15 page also shows £7.50, so check the amount shown at payment.

For MTD ITSA, annual plans cover 5 returns for one business at £15, 25 at £36, or 50 at £60. The £15 page also shows £7.50. No other fees are published in these facts.

Where it runs

Selftax is an online, web-only service. The facts list no iPhone or Android app and no desktop software or self-hosted option.

Its HMRC workflows support online authorization and submission for Self Assessment, VAT and ITSA filings. The VAT process uses a spreadsheet template that is uploaded and reviewed before direct submission.

Protection and rules, as published

Selftax states that it is registered with the UK Information Commissioner's Office for data protection under licence number ZB689779. Its privacy notice names Kaneez Safdar as Data Protection Officer and gives a London postal address.

The terms say the site, its original content, features and functionality are SelfTax proprietary intellectual property. The published facts do not state deposit protection, two-factor sign-in, a financial-services licence or a specific dispute process.

Strengths

The guided wizard is intended to help people complete returns without accounting experience. Coverage includes several UK Self Assessment situations and online partnership returns.

A free account lets you prepare before paying at submission. Support channels include live chat, email, video support and a contact form.

HMRC-connected workflows cover Self Assessment, VAT and ITSA. HMRC lists Selftax for agents and individuals, with most SA100 and SA800 schedules, attachments and amendments supported.

Catches to check

Selftax runs only in a web browser, with no published mobile app or self-hosted deployment.

The supported-schedule list excludes SA103L and SA803. Partnership filers still need individual returns. Annual MTD plans limit the number of returns and, for the entry plans, apply to one business.

The MTD ITSA page states mandatory thresholds begin in April 2026 above £50,000 income, April 2027 above £30,000 and April 2028 above £20,000. The £15 annual plan pages also display £7.50, so pricing should be checked before payment.

Who should skip it

Selftax may not fit anyone needing a phone app, desktop installation, self-hosting or state tax filing. It may also be unsuitable when the return needs excluded schedules SA103L or SA803.

Verdict

Selftax suits UK individuals, landlords, sole traders, partners and other filers whose cases match its published Self Assessment coverage and who are comfortable working in a browser. Its free preparation model and one-time Standard fee make the basic cost clear, while Premium adds consultant involvement.

It is less suited to people seeking mobile or installed software, state returns, self-hosting or excluded HMRC schedules. Businesses and professionals should compare the return limits and annual charges on the MTD VAT and MTD ITSA plans with their filing volume.
