TaxNav – What You Need to Know

How TaxNav Handles MTD Compliance

TaxNav covers all three qualifying income categories — self-employment (SA103), UK property (SA105), and foreign property (SA106) — under a single licence, with no additional charge for covering multiple income types. Users can submit via direct manual entry within TaxNav's interface, or via its bridging mode which accepts Excel, Google Sheets, and Apple Numbers files. Quarterly updates are submitted as cumulative year-to-date summaries, not transaction-by-transaction data — HMRC only sees the summary totals. Each new update replaces the previous one as all periods are cumulative from the start of the tax year. The Final Declaration (replacing Self Assessment) is supported, and users can add additional income items such as bank interest, capital gains, and pension contributions at year-end. Agents and accountants can submit on behalf of clients via HMRC's Agents Gateway.

TaxNav also supports users opting to report using calendar quarters (1 April to 31 March) rather than the standard tax quarters. Both cash and accrual accounting methods are supported.

TaxNav: No Property Management Capability

TaxNav was designed as a compliance and filing tool. It does not include property portfolio tracking, tenant management, rent tracking per property, joint ownership automation, compliance document alerts, HMO support, or mortgage tracking. For joint property owners, TaxNav's FAQ confirms that each owner can keep full digital records of their share of income and expenses, or record single totals quarterly — but this is handled manually by each individual co-owner, not automated by the platform.

TaxNav: Guided Digital Record-Keeping with Spreadsheet Bridging

TaxNav offers two approaches to digital record-keeping. Users can enter income and expenses directly within the platform via a clean, guided interface — transactions can be entered daily, weekly, or at quarter-end, and edited before submission. Alternatively, TaxNav's bridging mode allows users to maintain their records in Excel, Google Sheets, or Apple Numbers, import quarterly summaries via TaxNav's import worksheet, and submit to HMRC without changing their existing workflow. TaxNav's FAQ notes that bank feeds and AI receipt capture are planned future features. The platform supports both cash and accrual accounting — offering more accounting method flexibility than RentalBux — but does not provide a formal chart of accounts, journal entries, double-entry bookkeeping, or per-property expense tracking.

TaxNav: AI Error Checking and Guided Expense Entry

TaxNav's primary automation feature is AI error checking — the platform reviews data before submission to catch potential mistakes. Real-time tax estimates update after each transaction entry or quarterly submission, helping users plan for their year-end tax bill. For expense capture, TaxNav relies on manual entry or spreadsheet import — there is no automated bank feed or OCR receipt scanning currently, though TaxNav's FAQ notes both are planned future additions based on user demand. Quarterly deadline reminders are built in to prevent missed submissions.

TaxNav: Real-Time Tax Estimates and Submission Transparency

TaxNav provides a real-time running tax estimate that updates after each entry or quarterly submission, giving users an ongoing view of their likely year-end tax position. The platform also provides a detailed view and download of all income and expense transactions — allowing accountants or users to review exactly what has been submitted. However, TaxNav does not produce formal profit & loss reports, per-property breakdowns, balance sheets, or trial balances. Its reporting is focused on MTD submission transparency rather than broader financial analysis.

TaxNav: Agent Submissions, TaxNavHQ, and Browser-Based Mobile Access

TaxNav supports accountant and agent access: agents can submit on behalf of clients via HMRC's Agents Gateway. TaxNav also has a dedicated product for accountants — TaxNavHQ (taxnavhq.co.uk) — designed for practices managing multiple clients under MTD, where accountants can review client transaction data and support the year-end declaration process. The platform is browser-based and works on any device including smartphones and tablets, but there is no dedicated native mobile app for iOS or Android. TaxNav's FAQ confirms that most users can start using the platform in under ten minutes and it works on iPad and smartphones via the browser.
