Key Tax Dates In 2024 For UK Businesses and Self-Employed

In the new year, it's essential for businesses and self-employed individuals in the UK to mark their calendars with important tax dates. Understanding and adhering to these key dates can help you avoid late payment penalties and ensure a smooth financial year ahead. In this comprehensive guide, we'll walk you through the crucial tax dates for 2024, covering everything from self-assessment tax returns to VAT payment deadlines.



Self Assessment Tax Return: A Crucial Obligation

One of the first and foremost responsibilities for self-employed individuals and small business owners is the completion of their self-assessment tax return. The deadline for submitting your online return for the 2023/24 tax year is 31 January 2024. Filing your self-assessment tax return on time is imperative to avoid late payment penalties.


Paying Taxes: The Essence of Fiscal Responsibility

Paying income tax is a fundamental obligation for individuals and businesses alike. The deadline for settling your previous year's tax bill falls on 31st January 2024. This encompasses income tax, capital gains tax, and any outstanding payments from the 2023/24 tax year.


Corporation Tax: Limited Companies Take Note

For limited companies, the corporation tax deadline is crucial. Ensure you file your company tax return and pay any outstanding corporation tax by the deadline, which typically falls nine months after the end of your accountingperiod.


Register for Self Assessment: A Prerequisite for the Self-Employed

If you're self-employed or a sole trader and haven't registered for self-assessment yet, it's essential to do so as soon as possible. This is necessary for calculating your tax bill accurately and avoiding potential penalties.


Capital Gains Tax: Understanding Your Liabilities

Individuals who have made a profit from selling an asset or business asset during the tax year may be liable for capital gains tax. Ensure you pay any capital gains tax owed by the relevant deadlines to avoid penalties.


National Insurance Contributions: Fulfilling Your Social Obligations

Self-employed individuals need to pay their national insurance contributions to secure entitlements to the state pension and other benefits. Keep track of the deadlines for these payments to avoid any disruptions to your insurance coverage.


VAT Registration Deadline: Crucial for VAT-Registered Businesses

For businesses that are required to register for VAT, ensuring timely registration is vital. Be aware of the VAT registration deadline to comply with HMRC regulations and avoid potential penalties.


Payment on Account: Managing Your Tax Liabilities

For those with significant tax liabilities, making advance payments on account is a prudent way to manage your financial responsibilities. The first payment on the account is due by 31st January, with the second payment due by 31st July.


End of the Tax Year: Wrapping Up Financial Affairs

As the tax year concludes on 5th April 2024, it's essential to finalise all financial transactions and ensure that your records are up to date. This includes making necessary adjustments to your accounts and preparing for the upcoming self-assessment tax return.


Annual Registration Deadline: Limited Companies Stay Compliant

Limited companies must ensure that they meet the annual registration deadline to maintain their legal status. Compliance with this deadline is crucial for avoiding penalties and ensuring the continued operation of the company.


Payment Deadlines for Small Businesses: Ensuring Financial Stability

Small businesses often face unique financial challenges. Staying on top of payment deadlines for various taxes, including income tax and corporation tax, is vital for maintaining financial stability and avoiding unnecessary penalties.


Filing Deadlines for VAT Returns: A Quarterly Affair

Businesses registered for VAT must adhere to filing deadlines for their VAT returns. Ensure you file your returns within the specified time frames to avoid late filing penalties.


Late Payment Penalties: A Costly Consequence

Late payment penalties can significantly impact your finances. Stay vigilant and adhere to all payment deadlines to avoid incurring unnecessary fines, which can escalate over time.


Important Dates for Payroll: Managing Employee Finances

For businesses with employees, it's crucial to stay on top of payroll deadlines. This includes filing payroll benefits online and managing PAYE tax codes to ensure accurate and timely payments to employees.

Self Employment and National Minimum Wage: Balancing Income and Expenses

Self-employed individuals must ensure that their income meets or exceeds the national minimum wage. Balancing income and expenses is essential for sustaining a viable self-employed business.


Interest-Free Loans: A Financial Strategy for Limited Companies

Limited companies may consider interest-free loans as part of their financial strategy. Ensure that any such loans are managed in compliance with HMRC regulations to avoid tax implications.


Paper Tax Returns: A Fading Tradition

The hidden savings tax trap and why changes to ISAs make it harder to put money away

By Charlie Flockhart • June 4, 2026
Do you know what your Personal Savings Allowance is? While most taxpayers in the UK will know the thresholds for Income Tax, a worrying few know the way in which personal savings can be subject to tax. With ISAs set for a significant overhaul, understanding the less tax-efficient saving options will soon be more important. How much tax do you pay on your savings? While your savings are not taxed, any interest generated by those savings could be subject to tax if it exceeds your Personal Savings Allowance. Depending on the rate of Income Tax you pay, your Personal Savings Allowance will differ. The thresholds are: £1,000 for Basic-rate taxpayers £500 for Higher-rate taxpayers £0 for Additional-rate taxpayers ISAs remain the more tax-efficient saving strategy as the interest generated from them is tax-free. It is therefore most effective to utilise the full £20,000 saving limit for an ISA as early in the tax year as possible to benefit the most from the accumulation of interest. How should tax on savings be managed? The main issue is that tax on savings is often overlooked, resulting in HMRC taking action for underpaid taxes. This will often manifest in a charge through PAYE, as employees are more likely to overlook this obligation. Those filing Self Assessment tax returns should already be declaring interest earned, so any compliance issue in that group points to a wider problem with handling tax obligations. When attempting to make the most of saving strategies, it is best to seek professional financial advice. This will be more important if the saving limit for Cash ISAs falls to £12,000 for under-65s in 2027 as proposed, leaving younger savers to have to find new ways to grow their wealth. Our professional team can help you to determine an effective saving strategy that suits your financial goals while helping you to be mindful of the tax obligations that you may face. We do not want to see anyone caught off-guard by an unexpected tax bill and understanding your exposure is vital for preventing this.

Salary sacrifice cap and the squeezed middle

By Charlie Flockhart • June 4, 2026
The £2,000 cap on National Insurance (NI) free salary sacrifice pension contributions was sold as a tax on high earners but, if you look closer, the opposite is true. In fact, the people most exposed are middle-income savers and the small businesses that employ them. For the so-called “squeezed middle”, it is yet another quiet hit to take. Why do the rules adversely affect middle-earners? From April 2029, salary sacrifice tax relief will continue to be available, but only the first £2,000 of employee pension contributions each year will be free of NI. Anything above that becomes liable to NI for both the employee and the employer and the full adverse effect is clear once the different rates of NI are accounted for. If a person’s total pension contributions are modest, say up to six per cent, those individuals who earn between £35,000 and £50,270 will pay an eight per cent NI charge on pension contributions above the £2,000 cap. By contrast, an individual whose earnings already exceed the upper earnings limit of £50,270 will pay employee NI at just two per cent on those same excess contributions. This imbalance in the NI system means that those on lower incomes could pay four times the NI rate on their pension savings in excess of the new threshold than the highest earners pay. How does this change affect employers’ National Insurance bills? Many employers currently share their own NI savings by topping up staff pensions, but a new 15 per cent employer NI charge on contributions above the cap makes those top-ups unaffordable for a lot of firms. As a result, some employees could see the overall efficiency of their pension saving above the cap fall by as much as 23 per cent once lost top-ups are counted. Even those who stay below the threshold are not safe, as the Office for Budget Responsibility (OBR) estimates that around 76 per cent of higher employer costs are eventually passed back to staff through weaker pay rises and trimmed benefits. Don’t wait for the change The good news is that there is time to plan, as the rules do not take effect until April 2029, which leaves room to act while current allowances still apply. If you are a middle earner, this is exactly the moment to review your pension strategy, weigh up complementary options such as ISAs and make sure your retirement plans stay on track.

Government summer savings spree adds complexity to VAT for hospitality and tourism

By Charlie Flockhart • June 4, 2026
When Rachel Reeves announced a temporary cut in VAT from 20 per cent to five per cent for family attractions and children’s dining over the summer holidays, the hospitality and leisure sectors broadly welcomed it. The scheme runs from 25 June to 1 September and is funded, according to the Treasury, by closing a tax loophole used by oil and gas companies with overseas operations. On the surface, this looks like good news worth welcoming. However, for the businesses applying the new rules, the reality of delivering the rate cut is more complicated than the headlines suggest. The rules shift from one service to the next How the cut works depends heavily on what is being sold. Admission tickets to amusement parks, water parks, zoos, museums, soft play and similar venues qualify, as do children’s and family tickets to cinemas, theatres and concerts. However, pay-per-ride attractions do not. Children’s meals only qualify when served from a clearly marketed, separate children’s menu. A smaller portion of an adult dish does not count, nor does a discounted adult meal or a takeaway. Season tickets and annual passes are generally excluded too. The result is that many businesses will apply two VAT rates at once on the same bill. Tills, accounting systems and front-of-house staff all need to handle that from day one, then revert again from 1 September. This adds an additional layer of complexity to VAT reporting that businesses need to consider right away. Encouraged, but not required The Government has urged businesses to pass the saving on to customers and the Competition and Markets Authority has new anti-profiteering powers to prevent unethical activity. Even so, there is no legal obligation to lower prices at the till and many businesses will weigh up rebuilding margin, reinvesting and matching competitors before deciding exactly what savings to offer to consumers. Given the wider cost challenges that businesses currently face, the scheme may not deliver the lift at the till that many customers are expecting. Right idea, wrong season? There is also a question of timing. The scheme targets the period when families already spend most on days out and when operators are near capacity. A cut would arguably do more for businesses in the quieter autumn and winter months. As designed, it looks more like household support than business stimulus. Any support for the sector is welcome, provided businesses seek the expert guidance required to manage obligations and make the most of any new opportunities.
