Corporation Tax Refund due

Where can I amend the CT600 form to include bank details for a HMRC to issue a refund. I am on the portfolio profile.

TinyTax doesn't currently include bank details in the CT600 submission, but the good news is you can easily add or update your bank details directly with HMRC.

The quickest way is through your HMRC Business Tax Account:

1. Sign in at https://www.gov.uk/log-in-register-hmrc-online-services
2. Go to your Corporation Tax section
3. Look for "Manage account" or "Bank account details"

Once your bank details are on file with HMRC, any refunds due will automatically be paid to that account.
