Tax Navigator

What Tax Navigator does

Tax Navigator is a specialist AI agent for Claude Cowork. Install the plugin, and it walks you through your Self Assessment and Making Tax Digital requirements step by step. It understands your situation, guides you through the filing process, checks you're ready before each stage, and tells you when you need professional help.

1. Situation Mapping

Tax Navigator starts by understanding your specific tax situation. It asks about your business type, income sources, business structure, and what records you're currently keeping. This helps it give you guidance relevant to your specific circumstances.

2. Process Navigation

It walks you through Self Assessment and MTD step by step. From registration through to filing, you understand what each step requires, what documents you need, and what deadlines apply. Following HMRC published processes.

3. Checkpoint Handling

Before each major filing stage, Tax Navigator verifies you're ready. Do you have all required documents? Are you prepared for the next step? If not, it guides you on what's missing and what to do.

4. Documentation Management

Tax Navigator tracks what documents you need for your situation — invoices, receipts, bank statements, records of expenses. It helps you understand what qualifies as an allowable expense under HMRC guidance and what records you need to keep.

5. Professional Coordination

When your situation becomes complex — significant investment income, property income, or unusual expenses — Tax Navigator tells you what kind of professional to speak to and what information to have ready. It helps you have a more efficient conversation with your accountant.

6. Completion Audit

Before you file, Tax Navigator checks everything is in order. Have you completed all required fields? Are your figures complete and accurate? Does your return match your records? It helps catch errors before submission.

Important: Tax Navigator provides structured guidance based on HMRC published processes. It does not provide tax advice, and cannot assess your specific tax liability or recommend tax strategies. For complex situations, we recommend consulting a qualified accountant. When Tax Navigator tells you to speak to a professional, that's because your situation needs personal professional judgment.

Frequently asked questions

What is Making Tax Digital (MTD)? ▼

Making Tax Digital is HMRC's initiative to keep tax records digitally and submit returns electronically. From April 2024, all sole traders and partnerships with turnover above £50,000 must use MTD-compliant software to keep records and submit Self Assessment returns. This means you'll use software like Sage, FreeAgent, Crunch, or HMRC's own tool to record income and expenses, rather than traditional spreadsheets or paper records. Tax Navigator guides you through what this means for your filing.

Do I need Tax Navigator if I have an accountant? ▼

Tax Navigator is designed to help you understand the process, not replace professional help. If you have an accountant, Tax Navigator helps you understand what they're doing and ask better questions. It also helps if you handle some aspects yourself while your accountant handles others. Many people use Tax Navigator to understand the requirements and then have an accountant review their work or handle the final filing. Tax Navigator tells you when you need professional advice and what questions to ask.

What tax situations does Tax Navigator cover? ▼

Tax Navigator covers Self Assessment filing requirements for UK sole traders, self-employed people, and partnerships. It guides you through registration, recording income and expenses, understanding allowable expenses under HMRC guidance, meeting filing deadlines, and complying with Making Tax Digital requirements. It covers situations with straightforward income and expenses. For more complex situations — like significant property income, substantial investment income, or unusual business structures — Tax Navigator will tell you when you need to speak to a qualified accountant. It's built on HMRC published guidance.

How current is the tax information? ▼

Tax Navigator knowledge bases are updated within 48 hours of HMRC publishing changes to guidance, rates, or requirements. This includes annual budget changes, new allowance rates, new rules for expenses, and regulatory updates. When HMRC changes a process or deadline, we update Tax Navigator immediately. You can always trust the information is current with the latest HMRC guidance.

Does Tax Navigator file my tax return? ▼

No. Tax Navigator guides you through the process and helps you understand what you need to do. You will still need to either file the return yourself using MTD-compliant software (like Sage, FreeAgent, Crunch, or HMRC's own software) or use an accountant. Tax Navigator tells you your options and what to have ready before you file. It walks you through understanding the requirements, but the actual filing is done by you or your accountant.
