## What This Means for Business Compliance
Following Autumn Budget 2024, many compliance‐related changes have gone or will go into effect from **6 April 2025** onwards. Businesses should be aware of: shifts in employer NICs, top-ups on Capital Gains Tax, carriage of carried interest, and changes in residency and non-dom status—all of which carry obligations for reporting, payroll, and tax filings.

## Major Compliance Areas
### Employer National Insurance Contributions (NICs)
- Rate increases and threshold reductions mean that more payments fall under obligation. Payroll systems must reflect a **15% employer NIC rate** from 6 April 2025. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-december-2024/december-2024-issue-of-the-employer-bulletin?utm_source=openai))
- **Secondary threshold** at £5,000/year means NIC liability starts earlier in the pay scale. Systems must categorize earnings properly. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-december-2024/december-2024-issue-of-the-employer-bulletin?utm_source=openai))
- Employment Allowance expansion (to £10,500 and removing caps) – companies must ensure eligibility and update claims. ([gov.uk](https://www.gov.uk/government/publications/employer-bulletin-december-2024/december-2024-issue-of-the-employer-bulletin?utm_source=openai))
### Capital Gains Tax Reporting
- Enhanced CGT rates and changing reliefs (BADR/IR) require accurate asset tracking and timing of disposals. Ensure your year-end or disposal plans align with the new rates.

### Carried Interest Taxation
- From **April 2026**, carried interest will be taxed within the Income Tax framework, along with Class 4 NICs, using a multiplier where qualifying. ([gov.uk](https://www.gov.uk/government/calls-for-evidence/the-tax-treatment-of-carried-interest-call-for-evidence/outcome/the-tax-treatment-of-carried-interest-government-response-and-policy-update-june-2025-accessible?utm_source=openai))
- Draft legislation forthcoming—tax advisors should participate in consultations to clarify qualifying criteria.

### Non-Dom and Residency Rules
- Abolition of remittance basis: foreign income and gains generally taxed from first year of residence, with special treatment only for the first four years. ([gov.uk](https://www.gov.uk/government/publications/autumn-budget-2024-overview-of-tax-legislation-and-rates-ootlar/841ddc37-58e0-4d3f-9b53-123e8903d274?utm_source=openai))
- Offshore trusts and inheritance tax shelters under review. Plans must reflect that trusts may no longer shield assets as before. ([gov.uk](https://www.gov.uk/government/news/chancellor-chooses-a-budget-to-rebuild-britain?utm_source=openai))
## Actions Businesses Should Take Now
- **Update payroll infrastructure** before April 2025 to handle new NIC rates and thresholds.
- **Review asset registers** and timings for disposals to plan for higher CGT rates.
- **Engage advisors** for carried interest planning if you operate or invest in funds, private equity, etc.
- **Assess your non-dom status** or those of key employees—bring forward or defer foreign income/gains as appropriate.
- **Train finance teams** to handle changes to inheritance tax, property reliefs, and sessional workers or small profits threshold adjustments.
## Scenario Example
- A tech startup founder expects to sell shares in 2025-26—if they arrange for disposal before 6 April 2025, BADR at 14% applies; after that, ordinary CGT rate of 18%/24% likely.
- A fund manager expecting carried interest should evaluate whether their carried interest meets “qualifying” criteria to apply multiplier and avoid full income tax + NICs burden starting April 2026.
