HMRC unveiled its Transformation Roadmap, a bold, five-year plan to modernize the UK tax and customs system. With ambitions for digital-first services, AI integration, and simplified processes, this initiative aims to enhance efficiency, combat tax evasion, and deliver better experiences for individuals and businesses.
1. Better, Digital Tax Management for Individuals & PAYE Workers
- A new PAYE digital service is set to launch soon—impacting 35 million employees. This will let users:
- View and update income, allowances, reliefs, and expenses directly via the HMRC app or Personal Tax Account
- Potentially submit expenses claims with supporting documents online
- View and update income, allowances, reliefs, and expenses directly via the HMRC app or Personal Tax Account
- HMRC aims for 90% of customer interactions to be digital by 2030 (currently ~76%).
- Paper correspondence will be largely phased out—saving ~£50 million/year (equivalent to ~1,500 nurses’ salaries). Only essential, vulnerable, or digitally-excluded users will receive it.
What you should do:
Ensure employees and clients are familiar with the HMRC app and Personal Tax Account ahead of the cutover. Highlight the importance of staying digitally connected.
2. Enhanced Self-Serve Tools & AI-Powered Support
- A refreshed Self-Assessment experience with streamlined registration and opt-outs.
- More use of AI tools in customer support, aiming for instant, personalized guidance—reducing call volumes and improving first-time error resolution.
- Launch of an online expenses service for PAYE taxpayers (2025/26).
What you should do:
Encourage clients and staff to explore HMRC’s digital toolkit—and be ready for AI FAQs on compliance. Consider integrating these tools into your advisory services.
3. Securing Revenue by Closing the Tax Gap
- HMRC revealed a tax gap of 5.3% (~£46.8 billion, 2023–24).
- Modernization of compliance through AI-driven data matching, third-party data pre-population, and more proactive investigation teams.
- Expansion of HMRC’s Compliance & Criminal Justice Academies, training over 21,000 staff in 2025–26 GOV.UK.
- Umbrella company PAYE liability—stronger regulations effective April 2026—will shift tax burden to recruitment agencies.
What you should do:
Support small business clients with stronger record-keeping, software adoption, and awareness of upcoming Umbrella PAYE rules.
4. Infrastructure Simplification & Workforce Development
- Streamlining the IT estate—phasing out legacy systems like outdated Corporation Tax platforms.
- Adoption of GOV.UK One Login for unified digital access.
- Raising internal expertise via training in cloud services, cybersecurity, AI tools, and other digital skills.
What you should do:
Stay alert for changes in HMRC system access and log-in methods. Prepare your team for managing identity transitions and new service integrations.
5. A Vision for the Future: Open Ecosystems & AI Integration
- Expanding e‑invoicing and embedding tax compliance automatically into business/accounting platforms.
- Developing APIs to support third-party AI models, enabling real-time advice and transaction classification.
- Enabling delegated authority—simpler third-party access, better privacy, and agent roles via secure digital systems.
What you should do:
Ensure your software and clients’ systems are ready to integrate with HMRC’s planned APIs. Prepare for a shift toward automated compliance.
6. Agile, Iterative Delivery Model
- Moving away from large fixed programs to sandboxed, small-scale tests with frequent updates GOV.UK.
- Ministerial leadership via the HMRC Board, with strong private sector insight and ongoing user‑testing GOV.UK.
What you should do:
Engage with HMRC consultations and pilots. Provide feedback on user‑testing, especially around agent use-cases and digital accessibility.
