A self assessment payment slip is a small but vital paper form sent by HMRC with tax notices. It comes with a tax notice or bill. The slip shows how much tax someone owes. It also gives the reference number for the payment.

Think of it like a receipt request. It tells HMRC who is paying, how much is being paid, and when it is due. Payments can be delayed or misallocated without slip.

Why Does HMRC Send a Payment Slip?

HMRC uses the slip to track payments. Every slip links to one tax account. It makes sure the money goes to the right place.

The HMRC payment slip self assessment helps taxpayers avoid mistakes. Instead of filling out many details, the slip already has key information printed. That saves time and reduces stress.

Who Needs a Self Assessment Payment Slip?

Not everyone in the UK pays tax this way. The payment slip is for individuals submitting self-assessment tax returns. These include:

  • Self-employed workers
  • Freelancers and contractors
  • Landlords earning rent
  • Investors making income from savings or shares
  • People with foreign income
  • Anyone with complex earnings outside normal wages

If HMRC asks for a self assessment, the slip usually arrives with the bill.

How Much to Pay?

Payments on account are advance tax instalments that cover income tax. The Class 4 National Insurance for self-employed people. They are calculated using the previous year’s tax bill. Each instalment equals 50% of that total liability.

The due dates follow a fixed cycle:

  1. 31 January – during the tax year.
  2. 31 July – after the tax year ends.

On 31 January, two amounts may be due:

  • The balancing payment for the previous tax year.
  • The first payment on account for the current tax year.

Both are usually combined into one total amount.

Reducing Payments on Account

Sometimes people who work for themselves pay too much tax in advance. These advance payments are called payments on account. If the upcoming tax bill looks smaller, it’s possible to ask for a reduction.

How to Reduce Payments?

A special form called SA303 helps reduce payments. This form can be sent online or on paper. It can be used anytime before the final tax bill is due.

When filling out the tax return, the option to reduce future payments is also available. The form allows adding a short note to explain why the payment will be smaller next year.

What Happens if Payments Are Too Low?

If payments are reduced too much and the final bill turns out higher, extra money will need to be paid. HMRC (the tax office) will also charge interest on the missing amount. In serious cases, they may add a penalty if the reduction is unfair.

An HMRC Self Assessment tax payment slip is usually sent in specific cases, such as:

  • With the annual bill in January or July.
  • As part of reminder letters before payment deadlines.
  • With notices about overdue or missing payments.

Some taxpayers never receive one, especially if they always pay online. For others who rely on traditional methods, the slip remains an important tool.

How the Payment Slip Is Used?

The slip gives flexibility to those who prefer not to pay digitally. It can be used to make payments:

  • At banks or building society branches.
  • By posting a cheque with the slip directly to HMRC.
  • At selected post office counters.

The main benefit of the slip is that it ensures each payment links correctly to the right tax account.
