What you’ll gain from taking part

As a Club 111 member, you’ll help us fine-tune TaxNav’s look, feel and functionality. Your feedback will help ensure the software is not only HMRC-compliant, but also genuinely user-friendly for real people.

You’ll be part of a user community, able to:

  • Share ideas and suggestions
  • Ask questions and get peer support
  • Help us build a better solution for self-employed individuals and landlords

What TaxNav can do for you

TaxNav is designed specifically for sole traders and property owners, including those with CIS deductions. It offers:

  • Simple recording of income and expenses
  • Excel spreadsheet import (template provided)
  • Quarterly submissions — these figures don’t need to be perfect — adjustments can be made before your final submission.
  • HMRC only requires summarised totals, and so no detailed transactions are sent.
  • A user-friendly dashboard with submission history and estimated tax calculations
  • Year-end completion – where you can make adjustments to your personal income, expenses and losses before completing your year-end return. This replaces the Self Assessment return.
  • You can opt out of the MTD IT program at any time during this tax year and revert back to your current method, without any penalties.

About TaxNav

TaxNav is a secure, browser-based solution that helps you meet your MTD for Income Tax obligations — simply, reliably, and fully online. Whether you’re a sole trader, a property landlord, or both, TaxNav gives you everything you need to stay compliant and in control.
