TaxNav review
A focused web app for HMRC quarterly updates and year-end declarations, from £6 monthly.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
TaxNav is browser-based software for UK sole traders, landlords and others managing Making Tax Digital for Income Tax. It supports digital income and expense records, quarterly updates submitted to HMRC, and a year-end final declaration with adjustments. Users can enter transactions directly or import spreadsheet figures. Its listed income types include self-employment, UK property and foreign property, making it relevant to people with those records to prepare rather than anyone seeking a general-purpose Self Assessment filing product.
The subscription has two paid options: Monthly Plan costs £6 per month, while Annual Plan costs £60 per year; prices are shown plus VAT. Both plans list quarterly updates and year-end submission, spreadsheet bridging, and coverage for self-employment and UK and foreign property. TaxNav also offers a 30-day free trial, not a permanent free plan. Before submission, users can view tax estimates and run AI error checking. Accounting can be set to cash or accrual, with reporting periods selectable. The annual option lowers the listed cost compared with paying monthly across a year, but requires an annual commitment.
Spreadsheet imports from Excel, Google Sheets and Apple Numbers, alongside direct HMRC submission and CIS deduction retrieval, shape TaxNav's fit for people already keeping records in those formats or needing to retrieve CIS deductions. It is a cloud service accessed on the web, with email and documentation support channels and GDPR listed as a compliance item. Its feature set is deliberately centered on MTD Income Tax workflows; people looking for general Self Assessment filing should consider a broader tax product. TaxNav is a practical match for UK sole traders and landlords preparing for MTD who want spreadsheet-based records and quarterly HMRC updates, but less suitable for needs beyond that focused workflow.
