A season ticket loan lets an employer lend an employee money, interest-free, to buy an annual travel pass, spreading the cost through payroll deductions. This guide explains when it stays tax-free in 2026/27 and when a benefit-in-kind charge can apply.
How Season Ticket Loans Work
A season ticket loan is simply an interest-free (or low-interest) loan from an employer to help staff buy an annual season ticket for commuting, with the employee then repaying the loan through regular payroll deductions over the following months, spreading the up-front cost of an annual pass.
The main tax question is whether the loan counts as a "beneficial loan" — one provided interest-free or at below a commercial rate — which can create a taxable benefit for the employee based on the interest they would otherwise have been charged.
The Beneficial Loan Exemption Threshold
HMRC exempts small, interest-free or low-interest employment-related loans from a benefit-in-kind charge provided the combined balance of all such loans to the employee does not exceed a set threshold (commonly £10,000) at any point during the tax year — many season ticket loans fall comfortably within this limit and create no tax charge at all.
If the total balance of all beneficial loans to the employee exceeds the threshold at any time in the year, the whole loan (not just the excess) can become subject to a benefit-in-kind charge based on the official rate of interest, calculated on the outstanding balance for the period it exceeded the limit.
Practical Points
Employers should track the combined balance of any other beneficial loans (such as a separate loan for equipment or a personal emergency) alongside a season ticket loan, since it is the total across all such loans that counts towards the threshold, not each loan viewed in isolation.
If a benefit does arise, it is usually reported on the employee’s P11D and Class 1A National Insurance is due from the employer, so it is worth checking the combined loan balance before assuming a season ticket loan is automatically tax-free.
Frequently Asked Questions
Is an interest-free season ticket loan always tax-free?
Not automatically — it depends on the combined balance of all beneficial loans provided to the employee during the tax year. If the total stays within the exemption threshold at all times, no benefit-in-kind charge arises, but exceeding the threshold can bring the whole loan into charge.
What is the beneficial loan exemption threshold?
It is the combined balance limit (commonly £10,000) below which small, interest-free or low-interest employment-related loans are exempt from a benefit-in-kind charge — check the current threshold, as it is reviewed periodically.
What happens if my season ticket loan balance goes over the threshold?
If the total balance of all beneficial loans to you exceeds the threshold at any point in the tax year, the entire loan (not just the amount above the threshold) can become subject to a taxable benefit based on the official rate of interest for the period concerned.

Do I need to report a season ticket loan on my own tax return?
Usually not directly — if a taxable benefit arises, it is normally reported by the employer on form P11D and reflected in your tax code or Self Assessment via that report, rather than something you need to separately track and declare yourself.
Does my employer pay National Insurance on a season ticket loan benefit?
If a taxable benefit arises because the exemption threshold is exceeded, the employer generally pays Class 1A National Insurance on the value of the benefit, in the same way as for other benefits in kind reported on a P11D.
Can I have more than one interest-free loan from my employer at the same time?
Yes, but the combined balance of all such loans — for example a season ticket loan plus another employer loan — counts together towards the exemption threshold, so having multiple loans increases the risk of exceeding the limit even if each individual loan seems small.
What is the "official rate of interest" used to work out the benefit?
It is a rate set by HMRC and reviewed periodically that is applied to the outstanding loan balance to calculate the notional interest treated as a taxable benefit when a beneficial loan exceeds the exemption threshold — check gov.uk for the rate that applies to the tax year concerned.
What happens to the loan if I leave my job before it is fully repaid?
Employers typically require any outstanding balance to be repaid on or before your final pay date, often by deducting the remainder from your final salary, so it is worth checking your employer’s loan agreement before resigning or being made redundant.
Does a season ticket loan cover any type of travel, or only rail season tickets?
It depends on the employer’s scheme — many cover annual rail, tram or bus season tickets for commuting, and some extend to combined travelcards, but the exact travel types covered are set by the employer rather than by a single HMRC rule.
Is a season ticket loan taxed the same way as a Cycle to Work scheme benefit?
No — Cycle to Work arrangements typically use a separate salary sacrifice and hire agreement structure with its own tax treatment, whereas a season ticket loan is assessed under the beneficial loan rules, so the two should not be compared directly when working out your tax position.
