PAYE Year End Prep and Benefits in Kind Checklist
For UK Limited Company Directors and Owner‑Managed Businesses
If you run payroll and offer staff benefits, the PAYE year end can feel like a trap waiting to spring.
Miss a deadline, mis‑classify a benefit, or file an incorrect P11D and you risk:
HMRC penalties and interest
Unhappy staff whose tax codes are suddenly changed
Paying more tax and Class 1A NIC than you actually need to
This guide walks you through exactly what to review before the PAYE year end, with a clear, practical checklist focused on benefits in kind and P11D reporting. Use it to stay compliant, tidy up your records, and spot tax‑saving opportunities for the 2025/26 tax year and beyond.
1. What the PAYE Year End Means for Limited Companies
The PAYE year runs from 6 April to 5 April, regardless of your company’s accounting year.
For a typical small UK company, PAYE year end means:
You’ve completed all payrolls for the tax year up to 5 April
You must make sure all pay and benefits for directors and employees are correctly reported to HMRC
You need to issue P60s and, where relevant, P11Ds
You must pay any Class 1A National Insurance due on benefits in kind
Remember:
As a director of your own limited company, you are an employee for PAYE purposes. That means your own benefits (company car, medical insurance, reimbursed expenses, director’s loans, etc.) must be reviewed in exactly the same way as those of your staff.
A clean PAYE year end gives you:
Confidence that HMRC is satisfied
Clarity on the true cost of employing staff
A solid base to streamline and, where possible, reduce tax and NIC in the next tax year
2. PAYE Year End Deadlines Every Director Should Know
For each tax year, the key dates are broadly the same. Using the 2025/26 tax year as an example (ending 5 April 2026):
5 April 2026 – PAYE tax year ends
By 19 April 2026 – Final payroll submissions (FPS/EPS) for the year
By 31 May 2026 – Give each employee (including directors on payroll) their P60
By 6 July 2026
File P11D forms (if you provide taxable benefits in kind that aren't fully payrolled)
File P11D(b) (your Class 1A NIC return on all taxable benefits, including payrolled ones)
Give employees copies of their P11D where relevant
By 19 July 2026 (post) or 22 July 2026 (electronic) – Pay Class 1A NIC shown on the P11D(b)
Miss the 6 July or 19/22 July deadlines, and HMRC can charge:
£100 per month (or part month) for every 50 employees for a late P11D(b)
Interest and penalties on late Class 1A NIC
The earlier you complete your benefits in kind review, the less chance you’ll be scrambling in June and discovering problems when it’s already too late to fix them neatly.
3. Common Benefits in Kind That Must Be Reviewed
Before PAYE year end, directors should run through a structured review of all benefits and expenses that might be taxable.
Here are the most common areas to check:
Company cars and fuel
Company cars provided to directors or staff
Fuel provided for private use (including “just topping up the tank”)
Pool cars that may not actually meet HMRC’s strict “pool” criteria
Company vans
Vans used privately (even occasionally) beyond “insignificant” private use
Double‑cab pick‑ups which can sometimes be treated as cars, depending on specification
Private medical and dental insurance
Health insurance policies paid by the company for directors/employees or their families
Health cash plans and dental plans
Life assurance and income protection
Relevant life policies
Group life, critical illness and income protection policies
Loans and director’s loan accounts
Cheap or interest‑free loans to employees/directors over the £10,000 threshold
Overdrawn director’s loan accounts, which can trigger a beneficial loan benefit if not charged at the official rate
Accommodation and household costs
Company‑provided accommodation
Payment of household bills, utilities or council tax for directors/employees
Phones, tech and broadband
More than one mobile phone per employee
Home broadband paid by the company where there was already a personal contract
Laptops, tablets and other equipment also used personally (some can be exempt if mainly for business)
Travel, mileage and expenses
Mileage paid above HMRC’s approved rates
Home‑to‑work travel in most cases (usually not allowable)
Client entertaining or staff entertaining that doesn’t qualify as exempt
Staff benefits and “perks”
Gym memberships
Vouchers and gift cards
Staff parties where the annual exemption (£150 per head) is exceeded
Long‑service awards and staff incentive schemes
Childcare and family benefits
Employer‑supported childcare (legacy schemes)
Nurseries funded or part‑funded by the company
If you’re unsure whether something is taxable, treat it as a red flag and get advice before assuming it’s exempt.
4. How to Check If Your Benefits Are Correctly Taxed
Here’s a step‑by‑step way to review your benefits before PAYE year end.
Step 1 – Gather your data
Pull together:
Payroll reports for the year (including any payrolled benefits)
Last year’s P11Ds and P11D(b) for comparison
Nominal ledger reports for key cost codes (e.g. motor expenses, insurance, staff welfare, entertaining, subscriptions)
Expense claim reports and company credit card statements
Director’s loan account transactions
Step 2 – Identify all potential benefits
For each category in section 3:
Mark any payment that could be a benefit in kind
Check whether it has already been:
Put through payroll and taxed in‑year, or
Included in a draft P11D working schedule, or
Genuinely exempt under HMRC’s rules
Step 3 – Check the valuation rules
Common problem areas:
Company cars – Are you using the correct list price, CO₂ emissions and fuel type?
Fuel benefit – Is fuel for private use being correctly included, or has the employee reimbursed private fuel in full?
Loans – Are beneficial loans over £10,000 correctly calculated using HMRC’s official rate?
Medical insurance – Are premiums allocated correctly to each employee and director?
Errors here affect both the employee’s tax and the company’s Class 1A NIC bill.
Step 4 – Separate what’s taxable from what’s exempt
Some benefits are exempt if they meet conditions, for example:
One mobile phone per employee, owned by the company
Trivial benefits (e.g. small gifts under the trivial benefit rules)
Annual staff parties within the £150 per head annual exemption
Professional subscriptions on HMRC’s approved list
Certain work‑related training
Make sure these are clearly documented as exempt so they do not end up on a P11D by mistake.
Step 5 – Confirm the correct NIC treatment
Broadly:
Class 1 NIC through payroll – For cash or cash‑like items (e.g. vouchers employees can spend like cash)
Class 1A NIC via P11D(b) – For most non‑cash benefits (cars, medical, accommodation, etc.)
PSA (PAYE Settlement Agreement) – For some minor, irregular or impracticable benefits where the employer chooses to pay the tax and NIC
If you’re consistently putting something through the “wrong” route, you could be overpaying or underpaying NIC.
Step 6 – Fix errors before 6 July
If you discover:
Benefits that should have been taxed but weren’t, or
Benefits that have been overstated
You usually have more flexibility to correct them if you act before you submit your P11Ds and P11D(b). In some cases, employees can “make good” by reimbursing the company for certain benefits before the 6 July deadline, which can reduce the Class 1A NIC due.
5. P11D vs Payrolling Benefits in Kind
What is a P11D?
A P11D is the form employers use to report most taxable benefits in kind provided to employees and directors during the tax year, where those benefits have not been fully taxed through payroll.
You must:
File P11Ds for each relevant employee/director by 6 July
File the P11D(b) to report the total Class 1A NIC due
Give employees a copy of their P11D so they understand the benefits HMRC will tax them on
What is payrolling benefits?
Payrolling benefits in kind means:
You register with HMRC to payroll one or more types of benefit
Each pay period you add the taxable value of the benefit to the employee’s taxable pay (for tax purposes only, not for NIC)
The employee pays the tax in real time through PAYE
You usually do not need to submit a P11D for those specific benefits (though you still submit a P11D for any non‑payrolled benefits)
You still have to:
File a P11D(b)
Pay Class 1A NIC on the total taxable value of the benefits, including those you’ve payrolled
Pros and cons for directors and small employers
Advantages of payrolling benefits:
No more surprise tax bills for staff – tax is spread through the year
Fewer P11Ds to prepare and reconcile each July
Cleaner employee communication and fewer queries about tax code changes
You can often spot and correct errors earlier because benefits are reviewed each pay period
Disadvantages/points to consider:
You need suitable payroll software and processes in place
You must register with HMRC to payroll benefits before the start of the tax year
Not all benefits can be payrolled (for example, certain accommodation and beneficial loan benefits)
HMRC has confirmed that mandatory payrolling of most benefits is coming in future years, so moving voluntarily now can help you get ahead of the change and reduce P11D admin over time.
6. How a Pre Year End Review Can Reduce Future Admin and Tax
The most efficient time to look at your benefits in kind isn’t June – it’s the months leading up to 5 April.
A structured pre year end review can:
1. Catch issues while you can still fix them cleanly
Correct under‑ or over‑taxed benefits before filing
Adjust payroll in March to fix recurring errors
Allow “making good” of certain benefits by employees before 6 July to reduce Class 1A NIC
2. Simplify your benefits package
You can review:
Whether company cars still make sense compared to mileage allowances or EV schemes
If private medical or other benefits should be cost‑shared with employees
Whether to replace messy ad‑hoc perks with a clearer, more tax‑efficient package
3. Decide whether to move to payrolling benefits
Pre year end is the ideal time to decide if, from 6 April, you want to:
Start payrolling some or all benefits in kind
Reduce or eliminate the number of P11Ds you need to file
Align your payroll, bookkeeping and HR processes ahead of future HMRC changes
4. Tidy up director‑specific issues
For owner‑managed businesses, the director’s position is often the most complex. A pre year end review is the time to:
Check the director’s loan account for potential beneficial loan charges
Review any personal expenses paid through the company and ensure they are:
Repaid, or
Correctly treated as benefits in kind, or
Properly recharged and evidenced as business costs
Confirm that any director‑only benefits are correctly reported and valued
5. Put better processes in place for 2025/26
Once you’ve done the review, you can:
Create or update a benefits and expenses policy so staff know what’s allowed and what will be taxed
Clean up nominal codes so taxable benefits are easy to track
Ensure your payroll system is set up for payrolling benefits where appropriate
Schedule internal checks quarterly instead of waiting until the year end
A few hours spent now can save days of firefighting every June and July.
