6 January - National Insurance cut

The main rate of Class 1 employee National Insurance Contributions (NICs) will be cut from 12% to 10%. It's reported that the average worker on a salary of £35,400 salary will save around £450 a year. Anyone earning more than £50,270 will save the maximum of £754 a year.

31 January - Deadline for online self assessment tax returns

This is the final date for those that are required to complete and file a self assessment tax return online. HM Revenue & Customs (HMRC) must receive your tax return by midnight.

This is also the deadline for amending your 2021/22 tax return.

31 January - First payment on account, and balancing payment, due

Payment on account in relation to your self assessment tax return means the first payment, and balancing payment, are due by midnight on 31 January. If you're late making payment then you'll incur an interest charge on the amount due, calculated based on the Bank of England base rate plus 2.5%.

31 January - Capital Gains Tax (CGT) payment deadline

Capital Gains Tax may apply if you're selling or have sold assets. The amount you owe will form part of your balancing payment. However, if you've sold residential property that isn't your main home then the gains must be reported and paid to HMRC within 60 days of the sale.

 

14 February - Deferral of National Insurance Contributions

The deadline to request a deferral of class 1 NIC for the 2023/24 tax year if you're employed is 14 February. After this date, any applications made before 6 April 2024 will only be entertained by HMRC if the employer(s) agrees to it. Of note for the self-employed, the deadline for this is 31 January.

3 March - Increase in rail fares

The government have frozen rail fares for January and February meaning a rise of 4.9% will take place in March.

6 March - Spring Budget 2024

The Chancellor, Jeremy Hunt, has confirmed this date for the Spring Budget, likely to be the last before a general election is called. The budget statement summarises economic performance, projections for the years ahead, as well as proposed tax and spending announcements.

23 March - End to temporary cut in fuel duty

An end to the 5 pence fuel duty cut that was originally introduced in March 2022 for a year and then extended again in 2023.

30 March - Customs Declaration Service (CDS)

31 March - Annual Tax on Enveloped Dwellings (ATED) returns

Deadline for amending ATED returns and settling any outstanding tax for the period from 1 April 2022 to 31 March 2023.

1 April - Increase in National Living Wage and Minimum Wage

The hourly rate for the National Living Wage of £10.42 will increase by 9.8% to £11.44. Those in the 18 - 20 age bracket will see a rise from £7.49 to £8.60 per hour.

1 April - A review of household and other bills

Given the end of the tax year is approaching, this is usually the date when broadband and mobile phone provisions, water supplies, TV licence fees, and Council tax are reviewed and price changes announced.

In the case of broadband and mobile phone suppliers, usually any increases are linked to inflation. In certain regions of England and Wales, there is a possibility of water bill increases being lower than initially anticipated. This is due to the fact that 12 water companies have faced a combined penalty of £114m for failing to meet pollution and leakage targets.

Councils can raise Council tax by 3% and also add another 2% for social care. Above this, they have to hold a referendum. Colour TV licence fees will increase by 6.7% to £169.50 per year.

Vehicle Excise Duty rates, also referred to as car tax, will be adjusted in line with inflation.

1 April - New energy price cap

The energy price cap for the second quarter of 2024 will be implemented.

1 April - 15 hours free childcare for 2 year olds

Reform to provide 30 hours of free childcare to all children under the age of 5 (for eligible working parents), and not just 3 and 4 year-olds, means 15 free hours of childcare for working parents of 2 year-olds.

1 April - Research & development (R&) tax relief

For accounting periods beginning on or after 1 April, a new merged R&D tax expenditure credit scheme replaces R&D tax relief for SMEs and the RDEC. Also, the threshold for being an R&D-intensive company reduces from 40% to 30% for accounting periods beginning on or after this date.

5 April - End of the tax year

This date marks the end of the tax year for 2023/24. Prior to this deadline you would be wise to review your financial matters and tax affairs, from a personal and business planning perspective (where relevant). Doing so can reveal if there are any tax breaks, allowances, or reliefs that you can, or should, be making use of.

It also highlights the tax changes that may be coming in for the following fiscal year and what, if any, opportunities you can make use of now that may then be closed off. In short it could potentially improve your tax profile, reduce your tax liability, and thus save you money. Click on the link above to find out more.

5 April - Pension contributions deadline

This is the deadline for making pension contributions that then qualify for tax relief in the 2023/24 tax year.

1 October - Energy price cap

5 October - Deadline to register for self assessment

If you have never completed a tax return before and need to do so, or have income, outside of employment, that breaches a threshold of £1,000, or you've sold assets at a gain, then you need to register for self-assessment.

In instances where your second income exceeds £1,000 then the 5 October deadline is following the end of the tax year in which you breached this threshold, namely the 2023/24 tax year. Doing so informs HMRC so that you can then get a Unique Taxpayer Reference (UTR) number and an activation code which are needed to file a tax return.

22 October - settle PAYE settlement

Last chance to settle PAYE settlement agreement tax and class 1B NIC liabilities for the 2023/24 tax year.

31 October - Deadline for postal self-assessment tax return

Apparently 500,000 taxpayers still complete their tax return by paper and through the post. This is instead of filing it online. If you prefer the paper method then this must be submitted by 31 October. If you fail to file it on time, then you'll have to complete an online tax return instead, due by 31 January. 

31 October - Statutory deadline for submitting PSA calculations

If applicable, it is necessary to provide HMRC with a calculation of the income tax and Class 1B NIC that is owed on an annual basis by the end of October. HMRC will carefully assess the calculation and provide confirmation if the basic calculation is deemed to be accurate. 

November - Autumn statement

Whilst not yet confirmed, and the fact that a general election could impact on the date of this event, the Autumn Statement is often delivered in November. It can be a condensed version of the budget with more reporting on the state of the economy and government finances, as well as potential tax changes.

30 December - opt into PAYE

If you choose to file your tax return online and have earnings that are subject to PAYE, you have the option to have any outstanding tax collected through your tax code over the course of the following year.

To be eligible for this option, your tax bill must be under £3,000 and you must file your online return by the specified date. The benefit of this is that any tax owed will be spread out over 12 months starting from April 2025, instead of having to pay a single lump sum by January 31, 2025.

Other deadlines to be aware of:

Corporation Tax

Corporation Tax deadlines and the filing of limited company accounts depend on your company's accounting period. Usually these are for 12 months but can extend up to 18 months for when you commence trading.

The Corporation tax return is for a 12 month period and the deadline dates that apply are as follows:

  • File accounts at Companies House, no later than 9 months after the end of your accounting year end date
  • Corporation tax payment due, by 9 months and one day after the end of your accounting period
  • Corporation tax return due, 12 months after your company’s chargeable accounting period

In the first year of your trading, the deadlines are different and both Companies House and HMRC will notify you of them.

General election

Finally, being a general election year means the date of 19 December 2024 is the last possible day by law that the government can call a general election. This is because that will be 5 years exactly since the last parliament met for the first time since getting elected. This means the election would be held on 28 January 2025.

UK tax deadlines you need to put in your calendar.
