Crunch review
A broad UK tax and bookkeeping platform for sole traders, with paid Self Assessment filing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Crunch is a UK online accounting and tax platform for freelancers, sole traders, contractors, landlords, investors and small businesses. Its paid Self Assessment service combines an online questionnaire and document uploads with review and filing by ACCA-accredited accountants. The wider product adds invoice creation, expense tracking, receipt capture, bank reconciliation, Open Banking imports and tax estimation for salary, dividends, sole-trader profit and rental income. It is aimed at solo and small-business users who want bookkeeping and personal tax work in one browser-based service.
Pricing is split between free accounting software and paid services. The Self Assessment plan costs £240 as a one-time annual price and includes accountant-prepared Self Assessment, allowable-expense review, HMRC submission and online document upload. A 14-day free trial is available. The free plan covers accounting software, while Self Assessment filing is paid or included in selected accounting packages. That structure makes Crunch more suitable for users who value accountant involvement and connected records than for someone seeking only a low-cost tax return.
Its ecosystem is focused on UK workflows: integrations include Brixx, Snap Lite, Tripcatcher, Open Banking and HMRC, while the platform supports HMRC-compatible Making Tax Digital. Cloud deployment and a browser extension support online access, with email, chat and phone listed as support channels. GDPR is listed as its compliance standard. Crunch’s breadth is useful for sole traders managing invoices, receipts, transactions and tax estimates together, but the web-only platform and £240 Self Assessment price narrow its appeal. Choose it for integrated bookkeeping with accountant-supported filing; consider a simpler tax-only option if those accounting features are unnecessary.
