The Certificate of Tax Deposit scheme

Under the Certificate of Tax Deposit scheme you can make deposits with HM Revenue & Customs (HMRC) for later use to pay off certain tax liabilities. These deposits attract interest on a daily basis for up to six years, and can be withdrawn at any time.

This guide explains how the scheme works and lists the taxes covered. It also sets out how to make a tax deposit, how to use a deposit to pay a tax liability and how to withdraw deposits from HMRC.

On this page:

An overview of the scheme

Under the Certificate of Tax Deposit scheme you can deposit money with HMRC and use it later to pay your liabilities for certain taxes. For a list of the taxes covered by the scheme, see the section 'Taxes you can pay with your deposits'.

Your tax deposits with HMRC attract interest on a daily basis for up to six years. For more information, see the later section 'Interest on your tax deposits'.

Every time you make a deposit to HMRC, you will be issued with a Certificate of Tax Deposit by HMRC. You must keep these certificates, as you'll need them later to use your deposits to pay a tax liability or to withdraw them.

Who can make tax deposits?

The scheme is open to:

  • individuals
  • partnerships - to pay liabilities of the partnership
  • individual partners - to pay liabilities that apply solely to them
  • companies
  • personal representatives - to pay liabilities of a deceased individual's estate
  • trustees - to pay liabilities of the trust

Taxes you can pay with your deposits

You can only use your tax deposits to pay your liabilities relating to the following taxes:

  • Income Tax (Self Assessment)
  • Class 4 National Insurance contributions (NICs)
  • Capital Gains Tax
  • Corporation Tax (Series 6 or earlier only)
  • Petroleum Revenue Tax
  • Petroleum Royalty
  • Inheritance Tax

Note that tax deposits can't be used to pay PAYE (Pay As You Earn), or Corporation Tax liabilities, other than those listed above.

Tax liabilities under investigation by HMRC

You can make a tax deposit to be held against a tax liability that is under investigation by HMRC. Using a deposit in this way can help stop late payment interest accruing on the amount owed while it's under investigation. Interest may be added to the value of the deposit depending on when the deposit was made.

Deposit made before the tax liability payment date

If you make a deposit before the due date of the tax liability under investigation interest will be added to the value of the deposit. The element of tax due that is covered by the deposit will be treated as being paid on its due date and will therefore not attract late payment interest.

Deposit made after the tax liability payment date

If your deposit is made after the date the tax liability should have been paid interest will not be added to the value of your deposit. However late payment interest charges will only be added up to the date the deposit was made.

Calculate interest on your tax deposits

You'll get interest on the value of your tax deposits on a daily basis from the date shown on your Certificate of Tax Deposit until the earliest of the following three dates:

  • the due date of the tax liability that you pay using the deposit (or part thereof)
  • the date you withdraw your deposit for cash
  • the sixth anniversary of the date on your certificate

You can leave your deposits with HMRC for periods beyond six years, but no further interest will be paid on them after that point.

Any interest that has accrued will be added to the value of your certificate when you use it to pay off a tax liability or when you withdraw your deposit. When you do either of these things, HMRC will send you a letter to confirm the exact amount of interest that you've received.

Rates of interest

When you make a tax deposit, HMRC will send you a letter to confirm the current interest rate that applies. This interest rate will apply to your deposit throughout its first year.

If you keep your money on deposit for longer than a year, then the interest rate applied in each subsequent year is the rate that's in force on the anniversary of the date shown on your Certificate of Tax Deposit.

For example, the interest rate that's in force on the second anniversary of your certificate will apply throughout the third year that your money's on deposit.

Tax on interest you receive

Any interest your deposits attract is paid gross (without tax deducted at source). You must therefore treat all of this interest as part of your income for tax purposes when completing your annual tax return.

When interest is not due

From 5 December 2008 there's no interest due against deposits of less than £100,000. This includes any weekly or monthly instalments that are less than £100,000 each.

You can use HMRC's interest calculator tool to check the level of interest accrued against a tax deposit you have already made under the Certificate of Tax Deposit Scheme.

How to make a tax deposit

Minimum and maximum deposits

Your first tax deposit must be for a minimum of £500.

The minimum for subsequent deposits is the lower of:

  • £250
  • the amount needed to bring your total deposits with HMRC back to £500 if it has dropped below that level (following payment of a tax liability, or because you've made a withdrawal)

There is no maximum amount for a tax deposit.

Each time you make a deposit you will be given a new certificate. You can't top up an existing certificate.

Making deposits

HMRC recommends that you make your deposits electronically. Paying electronically:

  • is safe and secure
  • gives you better control over your money
  • provides certainty about when your payment will reach HMRC
  • avoids postal costs and delays
  • may lower your bank charges
  • lets you pay at a time convenient to you

Making a deposit by CHAPS

You can use your bank or building society to pay by CHAPS.

CHAPS enables you to tell your bank or building society to make an immediate deposit that will reach HMRC on the same day provided you initiate the deposit within the time limit specified by your bank (usually between 9.00 am and 3.00 pm). CHAPS deposits can be more expensive than other methods but may be of benefit if you're making very large deposits.

To make the deposit you will need to let your bank or building society have HMRC's bank account details and then send a letter to HMRC to confirm the details of your deposit.

Bank working days are normally Monday to Friday excluding bank holidays.

Sort Code Account number Account name
08 32 10 12001039 HMRC Cumbernauld

Please take care if you need to enter our bank account details. If you make a mistake with the sort code or account number there may be a delay in issuing your certificate.

You will also need to provide your bank or building society with the following reference details:

  • CTD/followed by the depositors name

This will ensure that HMRC can issue your certificate without delay.

Once you've sent your payment you'll then need to send HMRC a confirmation letter (see below).

Confirmation Letter - information you'll need to provide

Your letter of confirmation to HMRC must contain the following information:

  • the name and address of the depositor
  • the date
  • the amount of the deposit
  • if the deposit is being made on behalf of a trust, provide the names of the trust and of all trustees
  • if the deposit is being made on behalf of an estate, provide the names of the deceased and of all executors

Send your letter to:
HM Revenue & Customs
CTD Team
Room E1.03
St Mungo's Road
Cumbernauld
G67 1YZ

The date on your Certificate of Tax Deposit will be the date your deposit is credited to HMRC's bank account.

Making a deposit by post

HMRC highly recommends that you make your tax deposits electronically using one of the methods described above.

However if paying by post your cheque should be made payable to 'HM Revenue & Customs only - CTD'

Your cheque should be accompanied by a covering letter including the following information:

  • the name and address of the depositor
  • the date
  • the amount of the deposit
  • if the deposit is being made on behalf of a trust, provide the name of the trust and of all trustees
  • if the deposit is being made on behalf of an estate, provide the name of the deceased and of all executors

Send your cheque and covering letter to:

HM Revenue & Customs
Bradford
BD98 1YY

The date on your Certificate of Tax Deposit will be the date HMRC receives your cheque.

How to use your deposit to pay a tax liability

If you want to use your tax deposits to pay a tax liability, you must send your Certificate of Tax Deposit to HMRC along with written instructions explaining clearly how you want the deposit to be used.

If you have more than one liability to pay, you can specify the order in which you want them to be paid with your certificate. If you don't specify an order, HMRC will start with the oldest liabilities first.

Send your certificate and instructions to the following address:

HM Revenue & Customs
CTD Team
Room E1.03
St Mungo's Road
Cumbernauld
G67 1YZ

If you don't use the full value of a certificate

If your instructions are to use only a portion of a certificate's value to pay a tax liability, then you must specify what you want to happen with the remainder of its value. HMRC can either:

  • repay the balance in cash
  • issue you with a Balance Certificate that you can use against a future liability (this certificate will have the same date as the original one that you've partly used)

Note: HMRC will not leave any balance due as a credit on your tax records.

If your tax liability is greater than the value of your certificate

If the value of your certificate isn't sufficient to meet your tax liability, then you need to arrange to pay the shortfall immediately to avoid or minimise late payment penalties and interest charges.

To get an up-to-date valuation of your certificate, taking into account any interest that may have accrued, please contact HMRC's Certificates of Tax Deposits team - see the final section of this guide for contact details.

Making late payments using a Certificate of Tax Deposit

If you pay a tax liability later than its due date using a Certificate of Tax Deposit dated before the liability's due date, you won't be charged late payment interest.

Paying another party's tax liability

Certificates of Tax Deposit are not transferable. However, you can use them to pay another party's liabilities if you submit a written request to HMRC's Certificates of Tax Deposits team - see the final section of this guide for contact details.

Interest on a deposit used to pay against another person's tax liability will be at the lower cash rate.

Note that without having to submit a written request, a company may use its tax deposits to pay the liabilities of any of the following:

  • its holding company
  • its subsidiary
  • another subsidiary of its holding company

How to withdraw a tax deposit

You can make a full or partial withdrawal of your tax deposits (including any interest that has accrued) at any time. HMRC will usually make these repayments within 12 working days.

To withdraw a deposit, send the relevant Certificate of Tax Deposit and a written request to HMRC's Certificates of Tax Deposits team - see the final section of this guide for contact details.

HMRC will make a repayment to you using the CHAPS system or by payable order - you will need to let HMRC know your preferred option. The payable orders are made out to the depositor and sent to the address shown on your written request for withdrawal.

Interest on deposits you withdraw

For the purposes of calculating the interest due on deposits being withdrawn, the date of withdrawal is deemed to be either:

  • the day HMRC issues a payable order to repay your deposit
  • the day HMRC instructs its bank to credit your bank account

Notifying changes to HMRC

Where there are changes to named trustees or executors HMRC will need signed written authority, which must include:

  • their signatures confirming their agreement to the change(s)
  • certificates reference number

Send the written authority to HMRC's Certificates of Tax Deposits team - see the final section of this guide for contact details.

What to do after a death

If an individual named on the Certificate of Tax Deposit dies, HMRC will need signed written authority to deal with the proceeds and / or amend the Certificate. This authority must include:

  • the full name of each trustee or executor
  • their signatures confirming their agreement to the change(s)
  • the Certificate reference numbers

Please send your written authority to HMRC's Certificate of Tax Deposit team. You can find their contact details in the final section of this guide.

HMRC require this information before they make any allocation or repayment from the deposit.

Top

Notifying you of changes to the scheme

In the event of changes to the operation of the scheme - such as the addition or removal of taxes from the list of liabilities covered - details will be published:

  • in a Treasury press notice
  • in the Edinburgh and London Gazettes
  • using any other method the Treasury considers necessary

HMRC will continue to accept deposits until HM Treasury gives notice that it is terminating or temporarily suspending the Certificate of Tax Deposits Scheme:

  • if the scheme is temporarily suspended, your existing deposits will not be affected in any way
  • if the scheme is terminated, you will have to use your deposits to pay a tax liability, or else withdraw them for cash within a specified period (which would be set at no less than six years)

If you lose a Certificate of Tax Deposit

If you lose a Certificate of Tax Deposit, you must tell HMRC's Certificates of Tax Deposits team in writing - use the address in the next section.

They will send you an indemnity form to complete and return. You can use this form to request that HMRC take one or more of the following steps:

  • use some or all of the deposit to pay a tax liability
  • repay some or all of the deposit to you
  • issue a new certificate to replace the lost one

Once HMRC has issued you with an indemnity form, your original Certificate of Tax Deposit will no longer be valid. If you subsequently find it, please send it to the Certificates of Tax Deposits team who will destroy it.
