FAQ

Questions people actually ask.

How does volume pricing work?

You pay per SA100 return filed. The more returns your practice files in a tax year, the lower the price per return: £15 at the lowest volume, down to £10 at 100 or more. Nothing monthly.

What is the promotional price?

The prices shown are promotional — 50% off the standard price, which is exactly double. The promotion runs until 14 January 2027.

Do I sign in differently from an individual filer?

Yes. Use Agent sign in: it takes you to the agent workspace, where you connect your Agent Services Account and see every client on one board. Individual sign in is for people filing their own return.

Do I need an Agent Services Account?

Yes — to file for clients you need your HMRC Agent Services Account and Agent Reference Number, and each client's 64-8 authorisation. We track the authorisation status for you.

Can I file all my clients at once?

Yes. Select as many clients as you like on the board, review each return and file them in one go. Every return is still filed on your approval, and each one counts towards your volume price.
