Thanks for joining TaxNav’s Club 111
All Club 111 members will be beta testers in HMRC’s pilot scheme, using our software to submit quarterly updates to HMRC under MTD IT. You can opt out at any time (there's no penalty), but this also means leaving Club 111.
Some of you have signed up to be part of our Focus Group, which goes a little further. In addition to beta testing, you’ll be invited to share feedback, tips, and questions with fellow members and the TaxNav team. This will help us improve the software from a real-user perspective.

Accessing our software
HMRC has just updated their APIs for the 2025/26 tax year. An API is (Application Programming Interface) is the set of rules and tools that allow different software programmes to communicate and exchange data. We’re working closely with HMRC on their API integration. You’ll have access to the software by the end of July at the latest, and possibly sooner.
How the beta test will unfold
We’re taking this step-by-step and there’s no rush. Here’s how things will roll out over the next few weeks and how to prepare.
1. Getting yourself ready
To help prepare for the beta phase, please do the following as soon as possible:
2. Mid-July 2025
At this point we’ll open up forum discussions, so all members have a channel for sharing their HMRC MTD IT & TaxNav experiences and learning more in the beta phase.
We’ll also send you a survey so we can align the software with your preferences. For example, your calendar quarters, whether you operate cash or accrual accounting.
3. End of July 2025
From this point you can sign up for your TaxNav account – we’ll send you a link to get going.It will take you through our one-off onboarding process.
This includes setting up your TaxNav account, password and 2-factor authentication preferred method, then connecting and synchronising your HMRC and TaxNav accounts.
Once you’re up and running
We want this to be a relaxed, supportive experience. Your first MTD IT quarterly submission isn’t due until 6 August 2025. Rest assured, this need only be a summary of your income and expenses for the quarter – not a full breakdown of every transaction. HMRC has said it will not make assumptions about accuracy, nor will it impose any penalties at this stage.
