Payrolling Benefits in Kind 2027 — Employer Guide

Payrolling benefits in kind 2027 is a major shift in how employers report staff benefits. From 6 April 2027, employers must report company cars, car fuel, vans, van fuel and medical benefits through payroll in real time. Income Tax and Class 1A National Insurance on those benefits move into each pay run. The old year-end P11D process starts to wind down.

If you run a limited company and give yourself or your staff a company car or private medical cover, this affects you. Your payroll software, your cash flow and your employees' take-home pay all change. The good news is that you have about six months to get ready. This guide explains what changes, when, and the steps to take now.

What changes on 6 April 2027

Today most employers report benefits after the tax year ends. You file a P11D for each employee by 6 July, then a P11D(b) to declare the Class 1A NIC. HMRC then adjusts the employee's tax code to collect the tax, often a year or more late.

HMRC describes that process as outdated, manual and retrospective. Under mandatory payrolling of benefits, the taxable value of each benefit is added to the employee's pay every pay period. Tax is then deducted through PAYE in the same year the benefit is enjoyed. HMRC expects this to stop Income Tax being collected in arrears for about 3.5 million people.

The headline changes for employers:

• Benefit values go on the Full Payment Submission (FPS) at every pay date, not on a form in July.
• Income Tax on those benefits is deducted through PAYE in real time.
• Class 1A NIC on payrolled benefits is reported in real time too.
• HMRC removes the estimated benefit deduction from employees' tax codes for 6 April 2027.
• Most employers will eventually stop filing P11D and P11D(b) forms altogether.

You can read the source material in HMRC's interim guidance on reporting benefits in kind in real time. It is still marked as draft, and HMRC has said final phase 1 guidance will follow in autumn 2026.

Mandatory payrolling of benefits: phase 1 and phase 2

HMRC originally planned to bring every benefit into payroll in one go. In June 2026 it split the change into two phases after feedback from employers and payroll professionals. The phased introduction page on gov.uk sets out the split.

For most small limited companies, phase 1 is the one that matters. Company cars and private medical insurance are the two benefits we see most often on director P11Ds. Both move into payroll from April 2027.

Benefits outside phase 1, such as gym memberships or non-cash vouchers, do not have to be payrolled until April 2028. You can choose to payroll them earlier by registering through HMRC's voluntary service.

Private medical insurance benefit in kind

Employer-provided medical benefits are in phase 1. If your company pays for private medical insurance for you or your staff, the taxable value must run through payroll from 6 April 2027. For many directors this is the first time medical cover will show on a payslip each month rather than through a tax code adjustment.

How payrolling benefits in kind works in each pay run

The mechanics are simple once your software is set up. You take the full-year taxable value (the "cash equivalent") of the benefit. You divide it by the number of pay periods in the tax year. You add that slice to the employee's taxable pay every period.

HMRC's own example uses a £2,100 benefit for a monthly-paid employee. That adds £175 to taxable pay each month.

Company car benefit payroll example

Say your company provides a car with a taxable value of £6,000 for the year. You pay yourself monthly. Under payrolling benefits in kind 2027 rules:

• £500 is added to your taxable pay each month (£6,000 ÷ 12).
• PAYE deducts Income Tax on that £500 alongside your salary.
• Class 1A NIC is due on the benefit value through real-time reporting.

The car's taxable value still depends on its list price and CO2 emissions. For the current percentages, read our guide to company car tax and BIK rates for 2026/27.

When the value changes mid-year

If a benefit's value changes part-way through the year, you recalculate the full-year figure. You take off what you have already payrolled. You then spread the balance equally across the remaining pay periods.

If you do not know the exact value at the start of the year, HMRC allows a reasonable estimate. You correct it in a later pay period once the real figure arrives. HMRC expects "every effort" to be made to get that estimate right.

Making good and the 50% limit

If an employee repays part of a benefit's cost (known as "making good"), you payroll the value after that expected repayment. Employees still have until 6 July after the tax year ends to make good.

There is also a safety net. Employers must not deduct more than 50% of an employee's pay in tax in any pay period. Any shortfall rolls forward where possible. Tax still unpaid at the year end goes through HMRC's P800 process, Simple Assessment, or Self Assessment. The HMRC page on uncollected tax has the detail.

Class 1A NIC in real time from April 2027

Class 1A NIC is the employer's National Insurance on benefits in kind. For 2026/27 the Class 1A rate is 15%, the same as the main employer NI rate. You can confirm it on the gov.uk rates and thresholds for employers page.

Under the new rules, Class 1A NIC real time reporting replaces the single year-end P11D(b) bill for payrolled benefits. HMRC confirmed two further points in September 2026:

• If you voluntarily payroll a benefit from 6 April 2027, you must also payroll its Class 1A NIC in real time. You cannot payroll the tax and leave the NIC for a year-end return.
• Class 1A on benefits voluntarily payrolled during 2026/27 still goes through the P11D(b), due by 6 July 2027.

HMRC has not yet published full detail on Class 1A payment references under the new system. Check gov.uk before your first 2027/28 pay run.

P11D changes 2027: what stays and what goes

HMRC says most employers will no longer need P11D or P11D(b) forms once the change is fully in place. That does not happen overnight. Here is where the P11D still applies:

• The 2026/27 tax year. File P11D and P11D(b) forms as normal by 6 July 2027. Pay the Class 1A by 22 July 2027 (19 July by cheque).
• Loans and accommodation you do not payroll. These stay voluntary, so they stay on the P11D unless you register to payroll them.
• Phase 2 benefits in 2027/28. Benefits outside phase 1 that you have not registered to payroll still go on a P11D for 2027/28.
• Excluded globally mobile employees. From 6 April 2027 you can choose to exclude these staff from payrolling. They stay on P11D and P11D(b). HMRC says the exclusion service is available from November 2026.

HMRC has confirmed there will be no change to the penalties for late or wrong P11D and P11D(b) returns. A late P11D(b) currently costs £100 per 50 employees for each month or part month it is late. See the gov.uk expenses and benefits deadlines page.

The new employee benefits statement

P60s and P45s will not carry detailed benefit information. Instead, employers must give each employee a separate statement of the benefits they received in the tax year. It must show which benefits were payrolled and their values. The deadline is 1 June after the tax year ends, and HMRC sets no fixed format.

What it means for limited company directors

Many owner-managed companies run a director-only payroll with one company car or a medical policy. Payrolling benefits in kind 2027 rules change three things for you.

Your monthly payslip changes. The benefit value now sits on your payslip every month. If you pay yourself a small salary, the tax on a high-value car can take a large share of it. The 50% limit protects you, but any shortfall still has to be paid.

Your tax code changes. HMRC will remove the estimated benefit deduction from your tax code for 6 April 2027. Any underpayment from earlier years stays in your code. In 2027/28 it may look as if you are paying tax on the car twice. You are not: one deduction clears the old year, the other covers the current year.

Your salary and dividend planning may need a rethink. If most of your income comes as dividends, you may need a higher salary to absorb the PAYE on payrolled benefits. Our limited company dividend tax 2026/27 guide explains how the two interact. For wider payroll rules, see our employer payroll and PAYE 2026/27 guide.

Employer readiness checklist for April 2027

HMRC's getting ready guidance lists the steps. Here is the practical version for a small employer:

1. List every benefit on last year's P11Ds. Mark which ones fall into phase 1 and which do not.
2. Decide on loans and accommodation. If you want to payroll them from 2027/28, register through HMRC's service. It opens in November 2026 and the deadline is 5 April 2027. Payrolling them avoids running two reporting processes side by side.
3. Check your payroll software. Ask your provider when it will support real-time benefit reporting. HMRC's Basic PAYE Tools will also be updated for April 2027.
4. Fix your information flow. Car changes, new medical policies and fuel card data must reach payroll before each pay date. Agree cut-off dates with fuel suppliers if fuel is hard to report in real time.
5. Plan for joiners, leavers and changes. Set a process for new company cars, returned cars and salary sacrifice arrangements during the year.
6. Tell your employees before April 2027. Explain that tax on benefits will come out of each payslip, that the estimate in their tax code will stop, and that old underpayments may still appear.
7. Budget for the Class 1A overlap. Set aside cash for the July 2027 P11D(b) bill as well as monthly real-time Class 1A.
8. Prepare the employee benefits statement. Set up a simple template so you can issue it by 1 June 2028 for the 2027/28 year.

Penalties: a soft landing in 2027/28

HMRC has promised a light touch in the first year. For 2027/28, inaccuracies in RTI returns caused by mandatory payrolling will not be penalised unless there is evidence of deliberate non-compliance. HMRC also says no penalty applies where you use a reasonable estimate because you lack information.

That easement has limits. Late filing and late payment penalties still apply, and so does late payment interest. From 2028/29, the normal penalty and interest rules apply in full to payrolled benefits. Treat 2027/28 as the year to get your process right, not a year off. The HMRC penalties and interest page has the current wording.

Getting help with the switch

Most small employers will handle payrolling benefits in kind 2027 with an updated payroll package and a clear monthly routine. The risk sits in the details: mid-year car changes, director payslips that cannot absorb the tax, and the July 2027 cash overlap.
