DTax Filer review
Low-cost UK Self Assessment preparation with paid HMRC filing and optional adviser review.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
DTax Filer is web-based software for individuals preparing UK Self Assessment tax returns. It supports SA100, SA101, SA102, SA103, SA104, SA105, SA106, SA107, SA109 and SA110 forms, covering employment, self-employment, partnerships, UK property, foreign income, trusts, residence and remittance information. As users enter income and expenses, the software calculates tax and lets them review and download the return. It is aimed at solo and small-business filers who want a low-cost online preparation tool, with an optional adviser review for more involved returns.
Pricing is structured per tax return. The £0 Freemium plan includes the listed HMRC forms and tax calculation, making it suitable for preparing a return without paying for online submission. The £14.50 Standard plan adds HMRC online submission while retaining the same forms and tax calculation. The £60 Assisted plan adds online submission, review by a qualified tax adviser, technical support for validation issues and chat support. The pricing presentation combines one-time-per-return wording with annual-based credits, so buyers should check how the selected return is billed before proceeding.
Its main strength is breadth within UK Self Assessment at a low entry price, particularly for filers with self-employment, partnership, property or foreign-income details. HMRC is the listed integration, and deployment is cloud-based through the web. The main trade-off is that the free tier prepares returns but does not provide online submission, while adviser involvement requires the Assisted plan. Choose DTax Filer if you want inexpensive UK return preparation or paid review support; choose another option if you need a mobile experience or filing outside the listed UK Self Assessment scope.
