Pie Tax review
A broad free app for UK self-assessment, with optional paid tax-assistant support.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Pie Tax is a UK self-assessment app for freelancers, sole traders, landlords, investors, contractors and other individuals filing with HMRC. It combines bookkeeping and tax preparation in web, iOS and Android applications. Users can import and categorise transactions, calculate tax in real time, store receipts, manage multiple income streams and accounts, create invoices, handle property income and submit self-assessment returns directly to HMRC. The free Pie App includes all app features, including HMRC submission.
Its strongest fit is for people who want tax filing connected to day-to-day financial administration. Bank transaction import uses TrueLayer and open banking, while Smart Match supports transaction reconciliation. Receipt storage and reconciliation help connect records with bookkeeping, and the combination of investment income, rental income, invoicing and multiple accounts gives the product a wider scope than a basic return-submission tool. That breadth should suit self-employed users with mixed financial activity, especially those who prefer web and mobile access rather than separate bookkeeping and tax products.
The main pricing distinction is between the free Pie App and the optional Tax Support plan. According to the vendor's pricing page, Tax Support costs £89 per year and adds unlimited access to tax support all year round plus dedicated tax assistant support. Email, chat and phone are listed as support channels. Pie Tax should appeal to solo and small users who need HMRC self-assessment alongside bookkeeping, receipts, invoices and property or investment income. Businesses seeking state filing or a larger-organisation platform should choose a more specialised alternative.
