“But why?”

Paula Veysey Smith • 23 July 2018

It’s that time of year again – 31st July, where some of us need to make a further payment to the Inland Revenue for our self-assessment tax return. “But why”, I hear you say, “don’t we pay enough already?!”. I get so many enquiries about payments on account at this time of year I have decided to repeat a blog of a few months ago which will explain why we need to pay both at the end of January and July.

Payment on Account is a tax payment made twice a year by self-employed people, and also Director Owners taking dividends, in order to spread the cost of the year’s tax. It is calculated by looking at your previous year’s tax bill, and is due in two instalments.

The Payment on Account can be thought of as a way of paying off some of your tax bill in advance. The first instalment is due on 31st January (the same day as your ‘balancing payment’, which clears your tax bill for the previous tax year), and the second is due on 31st July. For those of you entering the payment on account regime you will have to pay the tax due and then 50% again for the payment on account; the second 50% being due on the 31st July. It is intended to help you spread your payments out during the year – and, of course, to help provide the Exchequer with a financial boost in the middle of the year. In reality, it does facilitate the bringing forward of paying taxes as the tax due in any given year is paid in that year.

So, each of the two instalments of the Payment on Account will normally be 50% of your previous tax bill. So, if you paid £10,000 in the tax year for which you are filing your return, you will make the first Payment on Account of £5,000 on 31st January, and another payment of £5,000 on 31st July. This will include Class 4 National Insurance Contributions where applicable, but not student loan repayments or Capital Gains Tax.

There are some circumstances in which a Payment on Account will not be due. If your tax bill for the previous year was less than £1,000 after PAYE or other deductions at source, no Payment on Account is necessary. Similarly, no Payment on Account will be due if, in the previous tax year, 80 per cent or more of your tax was deducted at source.

Your first payment on account is always painful but it is less so if you consider it really a deposit in your Revenue bank account . . . and that means more of the money in your bank account is yours to spend!
You can also apply to have the Payment on Account reduced if you have a good reason to believe that you income in the following year will be less; this is often the case with dividends as a year with a high dividend declaration may be followed by a year with lower dividends and hence a lower overall tax bill. However be warned, if you do lower your payment on account and it turns out that you should have paid more the Revenue could charge you interest on the underpayment.

If you believe that you have a case to reduce your Payment on Account for the 31st July please do get in touch asap and we can review your case and, if appropriate, make an application to HMRC to do so.

Have you ever been a victim of identity fraud? It’s very unpleasant, can cause financial hardship and always causes distress. My own son himself found out that he had been appointed a Director of a bogus Limited Company with no knowledge! I have also included a guide further down as to what to do if you find yourself in this unfortunately situation.

Now you can be excused if you’ve missed the announcement of the latest price increases by Xero. Apart from a rather low key “Pricing Update” notice and customer emails there has been little else published on the internet explaining the latest round of increases in the Xero Plans. So, here’s your opportunity to understand how Xero’s recent update will impact the plan you are on.

With many tax payers facing yet another payment to the HMRC on the 31st July let’s answer some frequently asked questions about the Payments on Account System. When was this system first introduced? The Payments on Account system was introduced in the 1996–97 tax year , as part of the Self-Assessment overhaul. Before then, HMRC had a fragmented and less predictable system for collecting income tax from self-employed individuals and others outside the PAYE system. It was introduced to ensure that taxpayers pay tax closer to when they earn their income , rather than facing a large lump sum payment long after the end of the tax year. Why did HMRC introduce Payments on Account? There are three key reasons why HMRC introduced this system: Cash flow for HMRC : This undoubtably is a driving reason for Payments on Account as it spreads the inflow of tax revenue more evenly throughout the year rather than relying on one big payment annually after a tax demand was sent to the tax payer. Encourages prompt payment : Tax is collected in advance (based on the prior year’s bill), reducing the risk of default or late payments. Helps tax-payers budget : Although first going into the Payment on Account system is painful as your tax bill, and half of it again, need to be paid on 31st January. Once in though, it does avoid the shock of a large single tax bill by splitting the liability into two smaller payments. So how does the Payments on Account system work? Who Needs to Make Payments on Account? You’ll need to make payments on account if your tax bill is more than £1,000 and less than 80% of your tax is collected at source (e.g., via PAYE). When Are Payments on Account Due? There are two payments each year: 31 January – First payment on account for the current tax year 31 July – Second payment on account for the current tax year Each is 50% of your previous year’s tax bill (excluding Class 2 NICs and student loan repayments). Example: Let’s say your tax bill for the 2023/24 tax year is £6,000 . On 31 January 2025 : You pay the £6,000 balance for 2023/24 Plus a £3,000 payment on account for 2024/25 (50% of £6,000) On 31 July 2025 : You pay another £3,000 as the second payment on account for 2024/25 So by July 2025, you've prepaid £6,000 towards your 2024/25 tax bill. What Happens When You File Your Next Tax Return? When you submit your 2024/25 return: If the actual tax bill is £7,000 , you’ve already paid £6,000 , so you owe £1,000 by 31 January 2026. If it’s only £5,000 , you’ve overpaid and can get a £1,000 refund or offset it against future payments. If the bill is £7,000 your tax payment will be: on 31st January 26 £1,000 balance on the 2024/25 return bill AND half of the £7,000 (£3 500) balancing payment so £4,500 in total. £3,500 balancing payment on the 31st July 26. Can You Reduce Payments on Account? Yes you can. If you expect your income to fall, you can apply to reduce them through your HMRC online account or on the paper form SA303. But if you reduce them too much, HMRC may charge interest on the underpaid amount. Will Making Tax Digital for Self-assessment change the Payments on Account System? The short answer is No!
