HMRC can make a direct repayment into your account if you sent an EPS containing your bank details. If not, you would need to send a letter to HMRC informing them of your bank details.

HMRC only makes refunds to employers who do not owe money for any other taxes. Companies that have been dissolved or struck off would need to apply for a refund by letter.

Did you underpay HMRC because of a mistake you made in your Full Payment Submission or Employer Payment Summary? If so, you can correct it in your next regular report and have it added to your next PAYE bill.
