Petty cash: how to set it up and record it

This is general information, not tax or legal advice. Rules and rates change, so check GOV.UK or ask an accountant.

Petty cash is a small amount of physical cash kept for minor expenses, such as stamps, parking or a coffee for a client. Without a routine, it is easy to lose track of.

Set it up

  1. Decide on a float, such as £100, and an upper limit per purchase, such as £20.
  2. Name one person responsible for the tin.
  3. Keep it locked and separate from the till.
  4. Open a petty cash account in your books, with the opening balance equal to the float.

Record spending

  • Take a receipt for every purchase. If there is none, write a short note and have it signed.
  • Record each spend against an expense account, with the tax rate if you can reclaim VAT.
  • Keep receipts together, and attach or photograph them. See receipt management.

Top up the float

Withdraw cash from the bank to restore the float. Record this as a transfer from the bank account to the petty cash account, not as an expense. The expense was recorded when the cash was spent.

Count the tin regularly

  1. Count the cash.
  2. Add the receipts.
  3. Cash plus receipts should equal the float.
  4. Investigate any difference, and record it.

Do this weekly or monthly, and always before the year end.

Common problems

  • Receipts missing, so spending cannot be supported.
  • The float being used for personal items.
  • Cash handed out without a record.
  • Large purchases going through petty cash instead of the bank.

Is petty cash still needed?

Many businesses now use a company card for small spends, which leaves a clear bank trail. Cash is still handy for some things. If you rarely use it, consider dropping it.
