1. When is Your HMRC Tax Return Due?
If you’ve set up a business and need to file a tax return, then the deadline for is 31 January, following the end of the tax year. A tax year runs from 6 April to 5 April. That means your 2020/2021 self-assessment form return is due by 31 January 2022.
There are penalties for failing to file your tax return (or SA100 form) on time, that increases the longer you leave it. Even though you may be able to appeal against any penalties you receive if you have a reasonable excuse. HMRC isn’t very generous with what they consider reasonable and don’t consider a lack of understanding an excuse. Plus, don’t forget filing a late tax return can be one of the ways a tax inspection is triggered.
You can choose to complete a paper tax return instead of doing it online. However, the tax deadline for sending this to HMRC is the end of the October. You should also be aware, HMRC only accept paper returns in specific circumstances so chances are you’ll need to file your return online.
It’s also worth noting that if you are employed and self-employed, pay any tax you owe through your PAYE code if it is below the limit set by HMRC. You’ll need to file your tax return online by the 30th December and arrangements will be made to change the tax code used by your employer to deduct what you owe out of your salary. Your employer won’t be told why there is a change in your tax code; they will just deduct more income tax on your payslip.

5.1 Tell Us About You
You’ll need to start completing your return by filling out the “Tell Us About You” section. This section is your chance to check HMRC have the right personal information about you and for you to make any corrections necessary. For example, like a change of address. It will be pre-populated if HMRC has any of the information about you on their system already, but it still pays to check that everything is correct.
Some boxes like a phone number and email address are optional so it is up to you whether you want to provide it. However, it can be useful to add them in case HMRC need to contact you. Make sure that you:
- Check all your personal details;
- Ensure you tick the box to say you are UK Resident;
- Tick the box if you are entitled to blind person’s allowance;
- Enter information if you are making student loan repayments, the type of plan you are on and whether you are employed or self-employed.
Once completed you’ll move onto the tailor your return section where you tell HMRC about your different earnings. You can also remove any sections of the tax return that are not relevant to you.
5.2 Tailor Your Return
This section of your tax return lets you tell HMRC what types of income you have received and the types of income tax reliefs you want to claim that help to reduce your tax bill. There are three pages:
- Sources of income you have received like self-employment, employment or rental income;
- Interest and dividends;
- Income tax reliefs and allowances you plan to claim like the marriage allowance.
On the first page you’ll need to confirm the following:
- If you are an Employee and provide your employers name (if you’re unsure check your P45 or P60)
- Self-Employed, how many businesses you have and their names**
- In a Partnership
- Are a Landlord
- Receive foreign income
- Have made capital gains
** If you were self-employed during the tax year and your business turnover (not profit) is less than £1,000 then you can decide whether you claim the HMRC £1,000 trading allowance. It’ll mean you don’t need to declare your income but you also can’t:
- Create an allowable tax loss that they can use against future profits;
- Pay voluntary Class 2 National Insurance contributions to protect their full entitlement to state benefits like Pensions;
- Get a tax refund if you are a subcontractor under the Construction Industry Scheme (CIS);
- Claim maternity allowance or tax-free childcare because your earnings aren’t officially documented.
Page 2 contains a list of questions to tell HMRC about all the other types of income you received during the tax year including:
- Interest for example from UK banks, building societies or unit trusts;
- Dividends for example from UK companies or open-ended investment companies;
- UK pensions, annuities or state benefits;
- Child benefit and whether you earned more than £50,000 because you may need to pay the high-income tax charge;
- Lump sums, share schemes and life insurance gains.
If you made income tax losses during the tax year then you can let HMRC know about them here. This is because you may be able to offset these against your other forms of income. For example, investors who make a loss on an EIS company may be able to offset it against their capital gains or income tax.
If you made contributions towards a personal pension or retirement annuity, then you’ll be able to get tax relief on a certain amount of the contributions you make, currently up to £40,000. You’ll receive tax relief at the highest rate of tax you pay as long as you have:
- contributed to a registered pension scheme;
- received taxable UK earnings, such as employment income or profits from self-employment, or
- are a resident in the UK for some time during the tax year or sometime in the 5 preceding years and when you joined the pension scheme.
Finally, you’ll also be able to claim any other tax reliefs on things like:
- community investment tax relief;
- venture capital trust shares;
- maintenance/alimony payments relief.
Once you have tailored your tax return online to your personal circumstances, it’s time to start inputting the numbers. You’ll see all the sections you need to complete and be able to check your progress:
5.3 Employment Section
If you were employed by someone, you’ll need to enter your income from your P45 or P60. You should also comple more than one employment section if you had more than one employer during the tax year. You can claim tax relief on expenses that you paid for, but were not reimbursed by your employer; for example, if you had to work from home. If you own a Limited Company and have added yourself on the payroll, then you’ll also need to include details of this employment here too.
You’ll find a separate guide here to help you to complete the employment section of your tax return.
5.4 Self-Employment Section
You’ll be presented with the self-employment section if you have become self-employed, are a sub-contractor under the CIS scheme or are a registered foster carer. The first thing you’ll need to do is calculate your business turnover (excluding any SEISS grant you received. You can find out how to show your grant here). If it is less than £85,000, then you’ll be able to complete the short-form self-employment section which requires less information. Next, you’ll need to have your business expenses ready and then decide what tax reliefs like capital allowances and tax loss reliefs you want to claim.
You’ll find a separate guide here to help you to complete the self-employment section of your tax return.
5.5 Self-Assessment for the High-Income Child Benefit Charge
If you or your partner earn between £50,000 and £60,000, including through self-employment, then you’ll need to pay back any child benefit you have received in the form of an income tax payment. You can choose to do this by electing to stop receiving child benefit payments or paying the high-income tax charge by filling out an HMRC tax return. This charge claws back child benefits paid at a rate of 1% for every £100 you earn over £50,000. That means once your income reaches £60,000, you will not receive any child benefit.
You’ll find a separate guide here to help you to fill in your tax return for the high-income child benefit charge.
6. Paying Your Tax Bill
You can pay your self-assessment tax bill online in a variety of ways, including by direct debit, bank transfer and debit card. If you want to pay by bank transfer, then you’ll find the bank details on the HMRC website, unless your want to pay your self-assessment bill through your PAYE code.
HMRC takes non-payment of tax seriously and has the power to make you bankrupt and add penalties that escalate. That said, they will work with you if you are struggling to pay your tax bill. First of all, you must file your tax return in January. If you don’t you’ll face penalties until you do which only increase your debt. Once you know how much tax you owe, contact HMRC ASAP to discuss the situation with them. You can do this online or by phone and it means you can agree on a suitable repayment plan. By sorting out a repayment plan, it means you’ll freeze penalties and interest thereby stopping the amount you owe HMRC from escalating.
If you are due a repayment after filing your tax return, then be aware that there are significant delays with HMRC making tax refunds due to additional security checks taking place as a result of the increase in fraud as part of the Coronavirus pandemic. They are increasingly sending out SURF 1 and SURF 2 Tax Letters as part of their checks to request additional information as well as completed R38 forms.
