BBSI returns
BBSI returns are a breeze with the
ARKK Automation Platform.
Bank and Building Society Interest (BBSI) returns are annual reports submitted by financial institutions to HMRC, detailing interest paid or credited to account holders. This includes individuals, and non-individuals such as partnerships, associations, companies, clubs, executors and trustees, with UK addresses.

Does it affect me?
BBSI reporting will affect any UK banks and building societies with interest-bearing accounts, as this information is used to ensure accurate tax calculations, which can impact on your overall tax liability and any potential refunds.
What do I need to do?
Ensure that your bank or building society has your correct personal details. Regularly check your account statements for accuracy and report any discrepancies to HMRC to avoid issues with your tax records and ensure compliance.
What's the deadline?
The deadline for submitting a return is the 30th June each year, unless otherwise stated in your notice. It's important to be aware of this date to ensure that all necessary information is reported on time to avoid penalties.
