Employers face ongoing changes in tax and employment regulations that require careful attention. The December 2023 issue of the HMRC Employer Bulletin brings important updates that will affect payroll, tax responsibilities, and employee benefits. Staying informed about these changes helps employers avoid penalties and ensures compliance with the latest rules.
This article breaks down the key points from the bulletin, explaining what employers need to know and how to prepare for upcoming changes.
New PAYE Responsibilities in Labour Supply Chains Starting April 2026
One of the most significant updates is the introduction of new PAYE responsibilities for employers involved in labour supply chains. These changes take effect from 6 April 2026 and aim to improve tax compliance in sectors where labour is supplied through intermediaries.
What Employers Need to Know
Scope: The rules apply to businesses that engage workers through labour supply chains, such as agencies or subcontractors.
Responsibility Shift: Employers further up the supply chain may become responsible for PAYE deductions on payments made to labour providers.
Preparation Steps:
- Review current contracts and payment arrangements with labour suppliers.
- Update payroll systems to handle new reporting and deduction requirements.
- Train payroll staff on the new rules to ensure accurate compliance.
Example
A construction company hiring workers through a subcontractor will need to verify that PAYE is correctly applied to those workers’ earnings. If the subcontractor fails to operate PAYE, the construction company may be held responsible for deductions and payments.
Clarification on Optional Remuneration Arrangement Rules
The bulletin clarifies the rules around Optional Remuneration Arrangements (Opting Out of Salary Sacrifice) under section 228A of the Income Tax (Earnings and Pensions) Act (ITEPA).
Key Points
Definition: Opting out refers to employees choosing to receive cash salary instead of benefits provided through salary sacrifice schemes.
Tax Implications: Employers must ensure correct tax treatment when employees opt out, avoiding errors in PAYE calculations.
Record Keeping: Maintain clear records of employee choices and any changes to remuneration arrangements.
Practical Advice
Employers should review their salary sacrifice schemes and communicate clearly with employees about their options. Payroll systems must be updated to reflect any changes promptly.
Important Update on Tax Refunds
HMRC has issued an update regarding tax refunds, which affects how employers handle overpayments and refunds related to PAYE.
What Has Changed
Faster Processing: HMRC aims to speed up tax refund processing for employers.
Refund Claims: Employers can claim refunds for overpaid PAYE tax more efficiently through updated online services.
Documentation: Ensure all refund claims are supported by accurate payroll records and calculations.
Tips for Employers
Regularly audit payroll to identify any overpayments early.
Use HMRC’s online tools to submit refund claims.
Keep detailed records to support any refund requests.
Payrolling of Benefits in Kind
The bulletin provides guidance on payrolling benefits in kind (BIK), a method allowing employers to spread the tax on employee benefits across the year through payroll deductions.
Benefits of Payrolling BIK
Simplifies year-end tax reporting.
Helps employees manage tax payments more evenly.
Reduces the risk of unexpected tax bills.
What Employers Should Do
Register with HMRC to payroll benefits in kind.
Update payroll software to include BIK calculations.
Inform employees about how payrolling affects their tax payments.
Example
An employer offering a company car can payroll the associated tax, deducting the amount monthly from the employee’s salary instead of a lump sum at the end of the tax year.

Employment Rights Bill Autumn Consultations
The bulletin highlights ongoing consultations related to the Employment Rights Bill, which may introduce new employment protections and obligations.
What Employers Should Watch For
Changes to employee rights and employer duties.
Potential new reporting or record-keeping requirements.
Updates on dispute resolution processes.
Employers are encouraged to follow consultation outcomes and prepare for any legislative changes that could affect contracts and workplace policies.
