5 April 2018 – Last day of the 2017/18 tax year
Thursday 5 April is the final day of the 2017/18 tax year – and the date by which you need to have all your documents, statements, receipts and accounts in order. With a bit of luck, you’ll have done the vast majority of sorting for your Self Assessment submission back in January, so you should only have a few months of income and expenditure to organise.
Getting your accounts in order at this time of year will serve you well moving forwards, making tax returns easier and ultimately ensuring the taxman can get a full view of your yearly accounts if you’re ever subjected to an audit.
This date can also signify new changes for the year ahead, with the Government enforcing any new regulations they’ve floated over the past few months. These law modifications can be minor or major, so be sure to stay on top of the latest tax news and amend your processes accordingly so you don’t get stung.
6 April 2018 – First day of the 2018/19 tax year
The first day of the new tax year 2018/19 is when any of the aforementioned changes come into effect, but it can also function as the perfect starting point for better tax practices.
Use the 6 April, and new tax year, as an opportunity to take better care of your accounts and implement processes that make recording your income and expenditure significantly easier. Make the shift over to digital records as best as possible to start calculating tax as you go, and have organised trays at the ready for any physical receipts you need to keep hold of to claim expenses.
This is also a good point at which to change over to tax software if you haven’t already – which will make submitting future tax returns much easier (plus, it readies you for the Government’s Making Tax Digital initiative, which is being rolled out from April 2019 onwards). When you’re always up to date, there’ll be less room for surprises later down the line.
31 July 2018 – Second Payment on Account for the 2017/18 tax year
Alongside your Self Assessment, you’ll also be required to make two separate payments to HMRC in January and July. These are known as Payments on Account, and essentially serve as advanced payments to cover you for the upcoming tax year.
Each of the Payments on Account are 50% of your previous tax bill. So, for example, if you paid £4,000 in tax, you’d make one Payment on Account of £2,000 in January, and another in summer.
The deadline for your second Payment on Account is July 31 2018. Remember: this is for the 2017/18 tax year, based on the tax liability for 2016/17.
5 October 2018 – Deadline for Self Assessment registration for the self-employed and freelancers, or additional income earners
If you have recently become self-employed or have received additional income in the last tax year (2017/18) but have yet to make HMRC aware of your change in employment status or income, you must notify them and register for Self Assessment by Friday 5 October.
Missing this deadline will incur penalties. These can be up to 30% of the amount of tax that you owe, so it pays to be prepared.
Register online on the GOV.UK website to receive your 10-digit Unique Taxpayer Reference (keep this safe, you’ll need it when you submit your tax returns). The process can take up to 10 working days to complete – you’ll receive a letter with a code that is required for activation.
31 October 2018 – Paper tax return submission
If you have income from PAYE and a tax bill of less than £3,000 and want this to be collected by wage deductions over 12 months from April 2019, you must submit your paper tax return by 31 October 2018. This is subject to you having enough earnings to deduct the tax due.
If you prefer to do this online, you have slightly longer to submit your tax return.
30 December 2018 – Online tax return submission
GOV.UK’s online service is not only useful for completing and submitting your tax return, you can also use it to check your details, look at your previous returns and print out a hard copy of your tax calculation.
Check out the GOV.UK website for more information about paying your Self Assessment tax bill through your tax code.
31 January 2019 – Self Assessment online tax return deadline and first Payment on Account for the 2018/19 tax year
This is the biggest date of the whole year for many self-employed people and small business owners. If you’re earning any income outside of PAYE, you’ll need to submit what is known as a Self Assessment tax return, which is the document that tells HMRC what you earned, what you need to pay in tax, and the amount of money you need to pay back.
Self Assessment submissions are due by midnight on 31st January. Miss it, and you could end up being forced to pay a considerable penalty. You’ll also need to submit your first Payment on Account for the 2018/19 tax year on this date, with the second to follow six months down the line. If you owe any money for the previous tax year, the balancing payment will also be due on this date.
There are several ways to complete and submit your Self Assessment tax return. The first, and historically the most popular, is filling your document out by hand and sending it through the post. This submission method is slowly being phased out as people turn towards tax software instead.
You can also hire the services of an accountant to complete your tax return for you, and they will correspond with HMRC on your behalf if there are any issues or discrepancies.
6 April 2019 – 2018/19 tax year ends
And then we come full circle. The 2018/19 tax year draws to a close, and you’re ready to do it all over again!
Keeping a close eye on all the key tax dates is extremely important when you’re self-employed. Successful business owners have more money to invest in their companies because they meet all their tax obligations and keep their accounts organised. When you know which dates you need to be prepared for, you’ll have more time to spend focusing on your company rather than worrying about HMRC.
