HMRC RTI Benefits in Kind 2027: What UK Employers Must Know About Real-Time Payroll Reporting

Introduction: The End of the P11D Era

For decades, UK employers have reported employees' benefits in kind (BiK) annually via P11D forms. That is about to change. HM Revenue & Customs (HMRC) has confirmed that from April 2027, mandatory real-time reporting of benefits in kind via Real Time Information (RTI) will be phased in, starting with company cars, car fuel, vans, van fuel, and employer-provided medical benefits. This marks a fundamental shift in payroll compliance UK 2027 and beyond.

Published as part of the Finance Bill 2026-27, the policy paper (updated 23 July 2026) aims to modernise the taxation of benefits, reduce administrative burden, and align reporting with the government's broader digitalisation agenda, including Making Tax Digital (MTD) for Income Tax and VAT. For payroll teams, this means updating systems, retraining staff, and ensuring real-time accuracy — or facing penalties.

This article explains the scope of the changes, the impact on payroll systems, and the compliance steps employers must take.

Scope of Benefits Affected: Two-Phase Rollout

The move to HMRC RTI benefits in kind reporting follows a two-phase timeline:

Phase 1: April 2027

• Company cars and car fuel
• Vans and van fuel
• Employer-provided medical benefits

These benefits are already commonly payrolled voluntarily by many employers. From April 2027, payrolling becomes mandatory for these categories.

Phase 2: April 2028

• Most remaining benefits in kind (e.g., private health insurance, gym memberships, interest-free loans above £10,000, etc.)
• Employer-provided loans and accommodation — timeline to be confirmed

Employers should note that the classification of benefits may evolve. HMRC has indicated that loans and accommodation will be addressed later, possibly with separate rules due to their complexity.

This phased approach gives employers time to adapt, but the clock is ticking. Payroll teams should start planning now.

How Real-Time Reporting via RTI Works

Currently, benefits in kind are reported annually on P11D forms, with tax collected via the employee's tax code adjustment. Under the new rules, employers will include the cash equivalent of benefits in each RTI submission (Full Payment Submission, or FPS). This means the tax on benefits is deducted from pay in real time, just like salary or wages.

Key operational changes:

• Data fields: RTI submissions will require new fields for benefit type and value.
• Valuation: Employers must calculate the cash equivalent (e.g., using HMRC's company car benefit calculator) and report it each pay period.
• Frequency: Benefits must be reported each time they are provided — monthly or weekly, depending on the payroll cycle.
• Penalties: A temporary penalty easement for non-deliberate inaccuracies will apply during the first year (2027-28). After that, standard RTI late-filing and inaccuracy penalties apply.

This is a significant departure from the annual P11D process. Employers must ensure their payroll software can handle real-time benefit calculations and submissions.

Comparison with MTD for Income Tax and VAT

The BiK reform is part of HMRC's broader digital transformation, which includes Making Tax Digital (MTD) for VAT (mandatory since 2019) and MTD for Income Tax (mandatory from April 2026 for sole traders and landlords with income over £50,000).

Similarities include:

• Digital record-keeping: All require digital records and compatible software.
• Real-time or periodic submission: MTD mandates quarterly updates; BiK requires each pay period.
• Penalty reform: MTD introduced a points-based penalty system; BiK will adopt similar late-filing penalties after the first-year easement.

Differences:

• Scope: MTD applies to VAT and income tax; BiK is a payroll-specific reform.
• Frequency: MTD Income Tax requires quarterly updates; BiK requires each pay period (often monthly).
• Complexity: BiK valuation (especially company cars) can be more complex than typical income tax reporting.

Employers already compliant with MTD will find the transition smoother, as the underlying principle of digital, timely reporting is the same.

Impact on Payroll Systems and Compliance Steps

For many organisations, the shift to benefits in kind reporting changes will require significant system updates. Here are the key steps to prepare:

1. Audit Current Benefits

Identify which benefits you provide and whether they fall under Phase 1 (2027) or Phase 2 (2028). Pay special attention to company cars — you'll need accurate CO2 emissions, list prices, and fuel type data.

2. Upgrade Payroll Software

Ensure your payroll software supports RTI benefits fields. Most major providers (Sage, ADP, Xero, etc.) are updating their systems, but you should confirm timelines. Custom or legacy systems may need integration work.

3. Train Payroll Staff

Real-time reporting means no more year-end corrections. Staff must understand how to value benefits each pay period and input data correctly. Consider running parallel runs in 2026-27 to test processes.

4. Review Data Feeds

For company cars, you may need to integrate with fleet management systems to get real-time fuel and mileage data. For medical benefits, ensure insurer data is accurate and timely.

5. Prepare for Penalty Easement

HMRC will offer a temporary penalty easement for non-deliberate inaccuracies in the first year. Use this window to refine your processes, but don't rely on it — build robust controls now.

How AIGovHub CCM Can Help Monitor Payroll Compliance Controls

With real-time reporting comes the need for continuous monitoring of payroll compliance. AIGovHub's Continuous Compliance Monitoring (CCM) module can help organisations stay on top of the new requirements.

CCM connects directly to your ERP and payroll systems (including SAP, Oracle, Workday, and Microsoft Dynamics 365) to:

• Automate controls testing: Validate that benefit values are calculated correctly and reported on time.
• Detect anomalies: Use AI-driven anomaly detection (Z-score, IQR, temporal analysis) to flag unusual benefit values or missing submissions.
• Generate evidence: Automatically collect evidence of RTI submissions and benefit calculations for audit trails.
• Remediate issues: Trigger workflows when a control fails, with integration to Jira or ServiceNow.

By embedding compliance into your payroll process, CCM reduces the risk of inaccuracies and penalties, especially after the first-year easement ends.

Key Takeaways

• Mandatory payrolling of benefits in kind via RTI begins April 2027 for company cars, car fuel, vans, van fuel, and medical benefits.
• Most remaining benefits follow in April 2028, with loans and accommodation to be confirmed.
• First-year penalty easement for non-deliberate inaccuracies — use it wisely.
• Payroll systems must be upgraded to handle real-time benefit reporting and valuation.
• Continuous compliance monitoring tools like AIGovHub CCM can automate controls and reduce risk.
