## Summary of Key Changes from 6 April 2026
From 6 April 2026, the UK government will implement several tax law changes affecting employers and employees:
- **Expanded exemptions for reimbursed work costs**: Employers can reimburse eye tests, display screen glasses, seasonal flu vaccinations, and homeworking equipment without triggering income tax or National Insurance. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai))
- **Removal of tax relief on non-reimbursed homeworking costs**: Employees will no longer be able to deduct additional household utilities, business calls or home work expenses if these aren’t reimbursed. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai))
- **Construction Industry Scheme (CIS) returns**: Contractors must file CIS returns **every month**, including nil returns for months with no subcontractor payments. Failure to notify HMRC of inactivity or file nil return may lead to penalties reinstated fully. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai))
- **Labour supply chains (umbrella companies)**: Agencies and end clients in labour supply chains involving umbrella companies now share responsibility for ensuring PAYE, National Insurance, and Student Loan deductions are correctly applied. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-141/issue-141-of-agent-update?utm_source=openai))
- **National Insurance for periods abroad**: From tax year 2026-27, paying voluntary Class 2 NI while abroad is no longer an option. To purchase voluntary Class 3 NI contributions for overseas periods, individuals must have either 10 years continuous UK residency or at least 10 years of valid NI contributions. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-141/issue-141-of-agent-update?utm_source=openai))
## Compliance Steps Employers Must Take
| Task | Description | Deadline |
|------|-------------|----------|
| Review employee reimbursements | Align cost categories (eye tests, homeworking equipment, flu vaccines) with new exemptions so reimbursement doesn’t incur tax/NI | Before 6 April 2026 ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai)) |
| Assess CIS obligations | Ensure monthly filing systems are in place; track months with no subcontractor activity | April 2026 onwards ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai)) |
| Update contracts with umbrella companies | Clarify who is accountable for PAYE and NI compliance in labour supply chains | Effective 6 April 2026 ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-141/issue-141-of-agent-update?utm_source=openai)) |
| UK employees abroad | Determine eligibility to pay Class 3 contributions; end voluntary Class 2 abroad | Applies from 2026-27 tax year ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-141/issue-141-of-agent-update?utm_source=openai)) |
## Practical Examples
- **Example 1: Homeworking equipment**
Jane works from home and buys a laptop stand. If her employer reimburses it after 6 April 2026 and the expense meets the criteria, no Income Tax or National Insurance need be charged. Under previous rules, reimbursements were usually taxable. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai))
- **Example 2: A contractor with no subcontractors in a month**
Bob is a CIS contractor and had no subcontractor payments in July. From April 2026, he must file a **nil CIS return** or inform HMRC about inactivity. Otherwise, he risks penalties. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-april-2026/april-2026-issue-of-the-employer-bulletin?utm_source=openai))
- **Example 3: NI while abroad**
Lisa moved abroad in 2024 and has been paying Class 2 NI voluntarily, but when tax year 2026-27 starts, she must either meet the 10-year residency or contribution threshold to be eligible to pay Class 3 instead. Otherwise she loses the ability to make voluntary contributions for UK pension purposes. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-141/issue-141-of-agent-update?utm_source=openai))
## Key Takeaways
- These changes reflect the UK’s shift toward modern working patterns, including hybrid and remote work. Exempting reimbursements while removing deductions reduces complexity.
- Employers especially those using umbrella companies or in the construction sector should update payroll, reporting, and contractual workflows.
- Individuals planning retirement or with abroad work/life arrangements must reassess contribution strategies under the new NI rules.
