Payment processing and accounting: payment methods: Certificates of Tax Deposit (CTD)
The Certificate of Tax Deposit scheme enables customers to make payments which are held as deposits against future tax liabilities. Generally speaking, interest is paid on the deposit until it is surrendered against one of the liabilities listed in the CTD guide on the HMRC website, or repaid.
Details on the processing of CTDs can be found at DMBM201100.
Full details of the scheme are contained in the Prospectus which is available from the HMRC website.
