If the issue persists, check there are no special characters or spaces at the start or end of your business address.
This error occurs as HMRC doesn't allow any negative values.
For example, an employee’s pension year-to-date total is £20 and you refund them £30. This error will occur because HMRC won't accept a value of -£10.
This is also common if you refund the pension contributions in the first period of the new tax year.
The steps to resolve this depend on whether you're processing a pension refund for contributions taken in the previous year. If you're processing a refund for a previous year, follow steps to ▼process a manual pension refund.
This stops the refund from creating a negative YTD value. You'll still need to process the pension refund manually.
This will allow you to refund the employee without triggering the 4084 error.
If you're not processing a pension refund, check opening balances and other values:
