Key Accounting Dates for UK Businesses in July 2025

Staying on top of your accounting deadlines is crucial to keeping your business compliant and avoiding unnecessary penalties. July is a particularly busy month for UK companies, with important due dates for Corporation Tax, VAT, PAYE, employee benefits, and more.

In this post, we’ve compiled all the key accounting and tax dates for July 2025 to help you stay organised and prepared.

01/07/25 – Corporation Tax payment: 30 September 2024 year ends

If your company’s accounting year ended on 30 September 2024, your Corporation Tax payment is due by 1 July 2025. HMRC expects payment nine months and one day after the end of your accounting period.

Missing this deadline could result in interest charges and potential penalties, so it’s essential to plan ahead. Make sure your bookkeeping is up to date and your tax calculation has been reviewed in plenty of time to arrange payment. If you use an accountant, they should notify you in advance, but it’s always wise to double-check the deadline yourself.

You can pay Corporation Tax via online banking, debit/credit card, direct debit, or using HMRC’s online services.

4/07/25 – Employment-related securities: make good unrecovered PAYE on notional payments to avoid tax charge under s.222 ITEPA 2003

If your company has provided employees with employment-related securities (such as shares or share options) and there was a notional payment where PAYE couldn’t be fully recovered at the time, 4 July 2025 is the deadline for the employee to ‘make good’ any unpaid PAYE.

Making good simply means the employee reimburses the employer for the PAYE amount that couldn’t be withheld. If this isn’t done by 4 July 2025, the unrecovered PAYE will be treated as an additional taxable benefit, triggering a further tax charge under Section 222 of ITEPA 2003.

Employers should ensure affected employees are aware of the deadline and the consequences of missing it. Timely communication and clear payroll records are key to avoiding unexpected tax liabilities.

5/07/25 – PAYE settlement agreement: deadline to agree for 2024-25

If you want to use a PAYE Settlement Agreement (PSA) to cover certain expenses or benefits provided to employees in the 2024/25 tax year, 5 July 2025 is the deadline to have the agreement in place with HMRC.

A PSA allows employers to make a single annual payment to cover the tax and National Insurance on minor, irregular, or impractical-to-calculate benefits – such as staff gifts, small staff events, or non-cash vouchers.

You must agree the PSA with HMRC before this date; it cannot be backdated. Once in place, you’ll need to calculate the total tax and NICs due and pay by 22 October 2025 (or 19 October if paying by post).

This is a useful way to simplify reporting and prevent employees from being taxed on small perks, just be sure to get your application in on time.

5/07/25 – Non-resident landlord scheme: annual return to HMRC and certificate NRL6 to landlord

If you’re an agent or tenant making rent payments to a non-resident landlord under the Non-Resident Landlord (NRL) Scheme, 5 July 2025 is the deadline to submit the annual return (NRLY) to HMRC for the 2024/25 tax year.

Alongside the return, you must also provide the landlord with a certificate (form NRL6) showing the amount of tax deducted and paid to HMRC during the year.

Failing to meet this deadline can result in penalties and compliance issues. It’s important for letting agents and tenants to keep accurate records of all rent payments and tax deductions made throughout the year to ensure timely and accurate reporting.

6/07/25 – Employee benefits: P11D and P11D(b) for 2024-25

If your business provided employees or directors with benefits in kind during the 2024/25 tax year – such as company cars, private medical insurance, or interest-free loans you must file forms P11D and P11D(b) with HMRC by 6 July 2025.

• P11D: Details the individual benefits provided to each employee or director.
• P11D(b): Summarises the total benefits provided and declares the amount of Class 1A National Insurance due.

You must also give employees their personal P11D copies by this date.

Accurate and timely submission is crucial to avoid penalties and interest charges. If you’ve payrolled benefits instead (i.e. taxed them through PAYE), you still need to submit the P11D(b), but not the individual P11Ds unless you provided benefits outside the payrolling arrangement.

6/07/25 – Employee benefits: Make good non-payrolled benefits provided in 2024-25

If your employees received non-payrolled benefits during the 2024/25 tax year, such as private medical cover or fuel for a company car they can ‘make good’ the cost of those benefits by reimbursing you. The deadline for this reimbursement is 6 July 2025.

Making good reduces or eliminates the taxable value of the benefit. If the employee repays the full cost by this date, the benefit may no longer be taxable, potentially lowering their tax bill and your Class 1A National Insurance liability.

It’s essential to communicate this option clearly to employees and ensure any repayments are processed in full by the deadline to qualify. Proper documentation should be kept in case HMRC requests evidence.

6/07/25 – Employment-related securities: 2024-25 ERS annual return

If your company issued or managed any employment-related securities (ERS) during the 2024/25 tax year, such as share schemes, options, or other equity-based rewards – you must submit your ERS annual return to HMRC by 6 July 2025, even if there were no reportable events.

This includes both tax-advantaged schemes (like EMI, SIP, SAYE, and CSOP) and non-tax-advantaged arrangements. Each registered scheme must have its own return filed through HMRC’s online service.

Failure to file on time may result in automatic late filing penalties, starting at £100. Even if no activity occurred, a nil return is still required for any schemes you’ve registered.

Make sure all scheme details are up to date in your ERS online service and allow time for gathering accurate information before the deadline.

6/07/25 – Employee share schemes: registration of schemes established in 2024-25

If your company set up any new employee share schemes during the 2024/25 tax year, you must register them with HMRC by 6 July 2025 using the Employment Related Securities (ERS) online service.

This applies to all types of schemes both tax-advantaged (like EMI, CSOP, SIP, and SAYE) and non-tax-advantaged arrangements. Registration is a prerequisite for filing your ERS annual return, and failing to do so could lead to penalties and disqualification from tax benefits.

To avoid last-minute issues, make sure you’ve created a Government Gateway account with the appropriate ERS access, and gather all relevant scheme details in advance. Once registered, you must also submit an annual return for each scheme by the same 6 July deadline even if there’s been no activity.

6/07/25 – Termination payments and benefits: 2024-25 termination payments and benefits report

If your business made any termination payments or provided benefits in connection with employment terminations during the 2024/25 tax year, you must report them to HMRC by 6 July 2025.

This includes any non-contractual payments exceeding the £30,000 tax-free threshold, as well as benefits like continued use of a company car or payment in lieu of notice (PILON). These must be reported using the relevant forms often via the P11D and P11D(b) process.

Accurate and timely reporting ensures compliance with HMRC rules and avoids potential penalties. Make sure to keep clear records of all termination arrangements, including any tax and National Insurance contributions calculated or withheld.

6/07/25 – Director loans: close company election under s.187 ITEPA 2003 for all beneficial loans to a director to be treated as a single loan for calculating 2024-25 benefit

If your company is a close company and has provided a beneficial loan (i.e. interest-free or low-interest) to a director during the 2024/25 tax year, you can elect under Section 187 of ITEPA 2003 to treat all such loans as a single loan for the purpose of calculating the benefit in kind.

This election simplifies the calculation of the taxable benefit by consolidating multiple loans into one total balance, which can reduce administrative complexity and, in some cases, the resulting benefit charge.

To take advantage of this, the election must be made by 6 July 2025 the same date P11D returns are due. The election must be in writing and retained with your company’s tax records (it doesn’t need to be submitted to HMRC unless requested).

This is particularly useful for directors who have taken out multiple small loans across the tax year and want to streamline the reporting process.

07/07/25 – EFRBS: return of non-cash benefits provided to retired employees in 2024-25

If your company provided any non-cash benefits to retired employees during the 2024/25 tax year through an Employer-Financed Retirement Benefits Scheme (EFRBS), you must report these to HMRC by 7 July 2025.

EFRBS are unregistered pension-like arrangements often used to provide retirement benefits outside of the standard pension framework. Any benefits – such as accommodation, use of a vehicle, or other perks – provided to former employees must be reported using form P11D, and the relevant Class 1A National Insurance may also apply.

Timely and accurate reporting ensures compliance and helps avoid penalties. Make sure you’ve properly assessed the cash equivalent of any non-cash benefits and keep full records of how these were calculated.

08/07/25 – VAT return submission and payment (online): month-end or quarter 31 May 2025

If your business submits monthly or quarterly VAT returns, and your VAT period ended on 31 May 2025, the deadline to submit your VAT return online and make payment is 08 July 2025.

This applies to businesses using Making Tax Digital (MTD) for VAT, which is now mandatory for most VAT-registered businesses. You must submit your return through compatible software and ensure your VAT payment reaches HMRC by the same date.

To avoid late filing penalties or interest charges:

• Submit your return promptly through your MTD-compliant accounting software.
• Arrange payment by Faster Payments, Bacs, or Direct Debit, allowing for processing time.

Mark your calendar and allow for any delays – especially if paying near the deadline or relying on bank processing times.

14/07/25 – CT61: return and payment for quarter ended 30 June

If your company has deducted income tax at source – for example, on interest payments, loans to directors, or certain annual payments – you may need to complete a CT61 return. The deadline to submit the return and pay any tax due for the quarter ending 30 June 2025 is 14 July 2025.

Form CT61 is used to report and pay tax withheld under the Income Tax (Annual Payments) regime, typically by companies that aren’t financial institutions but have made payments that attract withholding tax.

To stay compliant:

• File the CT61 return by the due date.
• Pay any tax withheld to HMRC by 14 July.

Delays or errors can result in penalties and interest, so ensure your accounting records are reviewed in advance and any applicable payments are reported accurately.
