2-100 Interest rates on certificates of tax deposit (CTD)
From 23 November 2017, the CTD scheme has been closed for new purchases but existing certificates will continue to be honoured until 23 November 2023. Any certificates remaining after this date should be promptly submitted to HMRC for a refund. Any balances HMRC are unable to repay will be forfeited.
CTDs can be applied to settle most tax liabilities, except PAYE, VAT and corporation tax falling due under Pay and File
Rates of interest vary according to the period for which the deposit is held and whether or not the CTD is used in payment of tax. The rates in force at issue apply for one year; thereafter, the rate applicable is that on the most recent anniversary of the date of issue.
