“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.

The finish line isn't just a destination. It's proof of everything you put in to get there. “Nothing feels so good as when you've succeeded at something you set out to do.” We made it. Seven letters, seven posts, and one very important journey. If you've been following this series from the beginning, you'll know that back in January we started with a goal — a triathlon in July. And as I write this, sitting in the garden with an iced coffee and a medal around my neck, I can tell you: it happened.  R is for Reward. And it might just be my favourite letter of the lot.

Setting a goal is just the beginning. What keeps it alive — and keeps you moving towards it — is what you do in between. “Evaluating what you're doing is so important. What worked, what didn't, what can I do better?” We're six letters into the SMARTER framework now. We've covered Specific, Measurable, Achievable, Relevant and Time-bound. Today we reach E for Evaluate — and I'll be honest with you, I think this might be the most important letter of the lot.

A goal without a deadline is just a wish with good intentions. Here's why putting a date on it changes everything. “Having that end date is something that gives you the enthusiasm, the commitment, and the motivation to continue.” We're now on T in the SMARTER Goals series - and this one is beautifully simple. T stands for Time-Bound, or Targets. It means giving your goal an end date.

Short-term goals are more powerful when they're built towards something bigger. Here’s why relevance is what keeps you going when motivation dips. “Goals that are shorter term in nature, but built to a bigger vision, are the most motivating that you can get” So far in this series we've looked at S for Specific, M for Measurable, and A for Achievable. Now we come to R for Relevant -- and this one is about making sure your goals are connected to something that genuinely matters to you.
