Getting Started with Dext Solo for Businesses 

From April 2026, you’ll need to keep records of your business income and expenses in a digital format.

Dext Solo will enable you get ready for the upcoming changes to reporting earnings that HMRC will require.

What is the ITSA area?

We now have an ITSA area that will allow you to add your income and expenses to Dext Prepare and work alongside your accountant to submit this data directly to HMRC.

From April 2026, if your business and / or property has a gross total of £50,000 or more you’ll need to: 

  • Keep records of your business income and expenses in a digital format. 
  • Submit to HMRC using an MTD-Compatible software.
  • Send quarterly updates of the income and expenses of your business.
  • Finalise your business income and submit an end of period statement (EOPS) annually.  
  • Submit a final declaration of income annually.

How can I access the ITSA area?

Once your accountant has created a Dext Solo account for your business, you’ll receive an email inviting you to Dext Prepare.

By accepting this invitation, you’ll be able to access the ITSA area. 

From here you’ll be able to edit or add details for your Income Source as well as submit and view transactions. 

What is a Transaction Collection Method?

A Transaction Collection Method is the type of documents you’ll be submitting to Dext Prepare and also sending to HMRC. 

You can choose either:

  • Receipts and invoices – Submit your invoices and receipts to Dext Prepare through the web app or mobile app.
  • Bank – Connect to a bank feed to have your transactions automatically added to Dext Prepare or submit your bank statements manually through the web app.

Note: You’ll either have the option to add receipts and invoices, or bank statements. You won’t see both options.

The Transaction Collection Method will have been selected by your accountant when setting up the account in Dext Prepare.

We’d recommend reaching out to your accountant if you’d like to make any changes to this.
