What is Self Assessment?
Self Assessment is a system for working out and paying tax on your income, operated by HMRC (HM Revenue & Customs – formerly known as the Inland Revenue). You only need to do a Self Assessment form if you do not pay tax on your salary through PAYE. Self
Assessment tax return forms are issued every April, covering the previous 12 months (i.e. the tax year to 5 April just passed). For example, the Self Assessment tax return due on the 31 January 2021 is for the previous year’s work from April 2019 to April 2020.
Remember! In 2021, there isn’t a late fee if you file your tax return online by the 28 February for your 2019/2020 tax return.
Does it apply to me?
If you only have one PAYE job, and no income from anywhere else, you’ll probably never need to fill out one of these forms. HMRC will usually send you a tax return reminder when you need to send one – once you’ve registered for it once. However, if you realise you do need one and they haven’t cottoned on, it’s your responsibility to ask for it.
There are several reasons why Self Assessment may apply to you. Here are the main ones:
- You’re self-employed and have earned more than £1,000 this year from your self-employment
- You have income from letting any property or land you own
- You’re a company director
- You receive other untaxed income, or significant capital gains, and the tax due on it cannot be collected through a PAYE tax code
- You’re a member of Lloyd’s of London insurance and reinsurance market
- You receive annual income from a trust or settlement, or any income from the estate of a deceased person, and further tax is due on that income
- You have taxable foreign income, even if you’re claiming that you are not normally resident in the UK
- You’re a minister of religion.
For many people, their first brush with Self Assessment will be when they become self-employed. If you’re about to take that step, this guide from GOV.UK should point you in the right direction. Alternatively check out our article 9 tips to maintain positive cash flow for your freelance business.
Before getting started
Before you begin, gather all the paperwork you need. You don’t want to get three-quarters of the way through to discover that you’ve lost a crucial piece of data. This will most certainly try your patience!
And apart from anything else, if you’re required to fill in a tax return, keeping your paperwork up-to-date is actually a legal requirement. You’re required to keep a record of your income (and any capital gains) for at least 22 months after the end of the tax year.
However, if you’re in business and are self-employed as a sole trader or a partner, or have rental income, you need to keep the records for at least five years after the end of the tax year.
What you’ll need
You may be wondering what forms you’ll need in order to file your self-assessment. HRMC have published a comprehensive list of the required documentation, which can be found here.
But we’ve also made our own quick breakdown of the paper work you need:
- Your P60
- Details of any pay and taxable expenses and benefits received from your employer
- Bank and building society statements
- Cheque and paying-in book stubs
- Any dividend vouchers you have
- Your self-employment accounts
- Documentation about any capital gains that have been realised
- Information on other income including investments, savings, pensions, property or benefits you receive
- Paperwork on anything you can claim for, like self-employed expenses or charitable donations.
You don’t normally need to send any documents with your Self Assessment form. However, HRMC may ask to see these documents at a later date. To avoid any stress, make sure you keep a photocopy or digital copy and keep your records organised.
If you’re asked to send across any documents, send the photocopy and keep the original in a safe place.
You should now be ready to fill in those all-important forms!
What do I need to fill in?
Every HMRC Self Assessment pack includes the core tax return SA100 form. On top on this, the chances are you’ll have to fill in one or more additional sections.
The extra pages you’ll need to complete will depend on your circumstances. For example, self-employed status, capital gains and rental income all require different extra forms to be completed, so fill in those that apply to you and ignore the rest.
At the moment, you can choose a paper or online tax return. In the near future, all but the biggest exceptions (such as living in a rural area with no internet) will need to file online. If you want a paper copy, HMRC no longer send this to you. You must download the SA100 form from the website. When you file online, you’ll be asked questions that help determine which section of the return you need to fill out. Then, you’ll only be shown those relevant pages – so that helps eliminate a lot of confusion!
If you need help filling anything in, call HMRC’s Self Assessment helpline on 0300 200 3310. It’s open Monday to Friday from 8am to 8pm and on Saturdays from 9am to 5pm. You can also Tweet HMRC @HMRCcustomers. They provide general advice on Self Assessment and they’ll answer any questions you may have.
If any of your personal details change, or if you find that you or the tax office have made a mistake, let HMRC know as soon as possible.
You can only be penalised if your return is incorrect through carelessness or you’re deliberately misstating the figures.
Remember! You can be criminally convicted if you try to cheat the tax system.
When is the tax return deadline?
The tax year starts on 6 April and lasts until 5 April the following year. After 6th April in any year, you can file your tax return – and doing it early doesn’t mean you HAVE to pay the tax owed immediately (but can help you to know how much you need to set aside by the deadline to pay). The deadline varies depending on how you plan on filing your return:
- If you’re sending your completed papers back by post, your deadline is 31 October
- If you’re completing an online tax return, you have until 31 January the following year
- Any tax owing must be paid by 31 January (many Self Assessment taxpayers also have to make payments on account by 31 January and 31 July).
If you miss the deadline by just one day you could face a £100 penalty, regardless of whether you have no taxes to pay or have paid the tax you owe. For the 2019/2020 tax year Self Assessment, you won’t receive a late fee if you file online before the 28 February 2021.
If you don’t settle your bill immediately, you’ll also start paying further penalties and interest charges. Surcharges – effectively penalties – can apply if you’re significantly late. But if you pay all your tax on time, that can eliminate any late-filing penalty.
These are just a few of the good reasons not to leave your tax return until the last minute. If you do, there will also be no time to correct any mistakes, or to ask for help if you run into problems. Get started early; it’ll mean much less hassle for you in the long run!
How can I send it?
Most people file their tax return online. However, you can also send it by post.
By post
If you want to send your forms by snail mail, remember that the deadline is 31 October, so allow plenty of time.
Double-check that you’ve signed and dated everything, and that you’ve included all additional pages.
And finally, remember to take a photocopy of the whole thing, in case it gets lost in the post. HMRC won’t acknowledge receipt, although it will let you know when your form’s been processed. You can also send via recorded delivery if you want to make sure you have proof of sending and tracked receipt.
If you get your paper returns to HMRC by 31 October, they can calculate your tax for you.
They’ll also let you know the amount you need to pay by the following 31 January, and if you owe less than £2,000, they may be able to collect the money through your tax code rather than as one lump sum.
Online
The advantages of completing the form online are clear:
- There’s no hassle with paperwork
- Your forms won’t get lost in the post
- You’ll also buy yourself an extra three months, with a 31 January deadline
- You’ll receive an immediate acknowledgement that your form has been filed
- There’s an option to save the form, so you don’t have to complete the form in one sitting
- The HMRC software will automatically calculate your tax for you
- If you are owed any money by HMRC, you’re more likely to get it sooner because your form should be processed quicker!
To file your return in this way, you’ll need to register online and request an ‘activation PIN’ from the HMRC website. To do this, you’ll need your Unique Taxpayer Reference (UTR), which you’ll find on form SA100 of your tax return, and your National Insurance Number or postcode.
It can take up to a week to receive your account password and become fully registered, so don’t wait until the last minute! For information on how to do it, check out the HMRC website.
Once you’ve completed your form, just make sure you print a copy off or save one on your computer, so you can still refer back to it if necessary.
On completing your tax return…
Make sure you’ve included all the relevant pages. Once you’ve done this, send it off and wait for it to be processed to see if you owe money or are owed money.
Now you can sit back, relax, and enjoy a cuppa knowing your tax return is done and out of the way for this year.
If, however, you are finding the process less forgiving and are pulling your hair out trying to get to grips with all of those figures, get a professional to help.
The Chartered Institute of Taxation (CIOT) and the Institute of Chartered Accountants of Scotland (ICAS) have online directories of certified number crunchers. Look for someone who specialises in your area. For example, if you’re a freelancer, you need an accountant who specialises in advising freelancers. Ask around for recommendations too. Other freelancers in your industry may know someone who they can recommend.
Tips and tricks
Jane Moore, from the Institute of Chartered Accountants, has a few ideas to help you along the way:
- Make sure you SIGN your tax return on the last page!
- If you want to complete your tax return online by 31 January, you need to register online, here.
- Only fill in the boxes that apply, don’t write ‘nil’ or ‘0’, just leave them blank.
- You don’t have to send any of your records/papers with the tax return, but you must keep them for at least 22 months (and in some cases five years) after the end of the tax year.
- Make sure you claim any tax relief under the supplementary pages. For example, you can get relief on Gift Aid donations.
- Don’t be put off by claiming if you don’t have exact amounts. You can give estimates based on what you think you spend, or use receipts from half of the year to calculate the whole year’s estimates. For example, if you buy stationery every month and believe you spend about £20 on it that would be reasonable – anything outrageous may be investigated by the tax office.
- If you’re waiting for information which may have a bearing on your assessment, you can put your tax return in on a provisional basis including a note stating that this is the latest information and you will send the final figures through when you can.
- The extra two pages are there for notes. If anything new and varied from your last tax return has happened, explain it in your notes. HMRC uses risk assessment software to see who they should investigate, so if your income was half that of the previous year, just explain it in a note and they may be satisfied.
