The 968L tax code tells your employer to give you £9,680 of tax-free pay across the tax year, which is £2,890 less than the standard £12,570 personal allowance that most employees receive under code 1257L. The L confirms you still qualify for the ordinary personal allowance, so the lower number is the thing to focus on: HMRC has decided that £2,890 of your allowance needs to be set against something else. That “something else” is usually a taxable company benefit, an untaxed source of income such as the State Pension, or a tax debt from an earlier year being quietly collected through your wages.1GOV.UK. Tax Codes: What Your Tax Code Means
What the 968 and the L Actually Mean
Every PAYE code splits into a number and a letter. The number is your annual tax-free allowance with the final digit stripped off, so 968 translates to £9,680. Your employer’s payroll divides that figure evenly across your pay periods, giving you a slice of allowance each week or month before income tax starts.
The L suffix means you’re entitled to the standard personal allowance structure.1GOV.UK. Tax Codes: What Your Tax Code Means Most employees carry 1257L, reflecting the full £12,570 allowance that has been frozen through at least April 2028.2GOV.UK. Income Tax: Maintaining the Personal Allowance and the Basic Rate Limit A code of 968L means the full allowance is still your starting point, but HMRC has subtracted £2,890 of adjustments before working out the figure your employer uses.
Why Your Allowance Has Been Reduced by £2,890
Codes drop below 1257L whenever HMRC needs to collect tax on income or benefits that haven’t already been taxed at source. The usual causes behind a code like 968L are:3GOV.UK. Tax Codes: Why Your Tax Code Might Change
- A company benefit with a cash value, such as a company car, private medical insurance, or an interest-free loan. Rather than send you a separate bill, HMRC reduces your code so the tax comes out of your wages gradually.
- An underpayment from a previous tax year. If you owed less than £3,000 (or more, where your income is higher than £30,000), HMRC spreads the recovery across the current year’s pay by lowering your code.
- The State Pension, which is taxable but paid without any tax deducted. HMRC trims your employment code so the right amount of tax is collected through your salary.
- The High Income Child Benefit Charge, where you or your partner earn above the threshold and still receive Child Benefit.
- A Marriage Allowance transfer. If you’ve handed 10% of your allowance to a spouse or civil partner, your own code falls by £1,260 to reflect that.
With 968L, the £2,890 shortfall against the standard code is the combined total of whichever of these apply to you. One benefit might account for all of it, or several smaller adjustments might stack up. The only reliable way to see which is which is the P2 Notice of Coding, which breaks the figure down line by line.4GOV.UK.

What 968L Costs You Compared With 1257L
The practical effect of a reduced code is straightforward. Your employer subtracts £9,680 from your annual salary and taxes the rest. On a £30,000 salary that leaves £20,320 as taxable income. Someone on the standard 1257L code earning the same £30,000 would have only £17,430 taxed.
The gap is £2,890 of extra taxable pay. At the basic rate of 20%, that works out at roughly £578 more income tax across the year than a colleague on 1257L would pay on the same salary. If your overall income pushes any part of that £2,890 into the higher-rate band, the extra tax rises accordingly.5GOV.UK. Income Tax Rates and Personal Allowances
One thing a reduced code does not affect: your National Insurance. NI runs on its own thresholds and is calculated from your gross pay regardless of what tax code you’re on.6GOV.UK. National Insurance Rates and Categories
How to Check What’s Behind Your 968L
Before deciding whether 968L is correct, confirm what HMRC thinks it’s collecting. Sign in to the “Check your Income Tax” service through your Government Gateway or GOV.UK One Login account and look at the current year’s coding breakdown.7GOV.UK. Tax Codes: If You Think Your Tax Code Is Wrong You should see the £12,570 allowance at the top and the deductions listed underneath, netting to £9,680.
Cross-check those deductions against the real world. If your employer has given you a P11D listing taxable benefits, the values on it should line up with the company-benefit entries in your code. Mismatches on the P11D are one of the most common reasons a code is wrong.8GOV.UK. Your P45, P60 and P11D Form: P11D Equally, if the code still carries an adjustment for a previous-year underpayment you’ve already settled, or for a benefit you no longer receive, that’s a reason to update it.
Fixing the Code if It’s Wrong
You can correct the information online through the same service, or by phoning HMRC. Have your National Insurance number ready, along with your employer’s PAYE reference from your payslip or P60 (it looks like 123/AB456).9HMRC Design Patterns. Employer PAYE Reference Once HMRC accepts the change, a new code goes to both you and your employer within 15 working days.7GOV.UK. Tax Codes: If You Think Your Tax Code Is Wrong
If you’ve only just started a new job, HMRC asks you to wait 35 days before getting in touch, because it takes time for your new employer’s payroll data to reach their systems.
Getting Back Tax You’ve Overpaid
Where a wrong code has pulled too much tax from your wages, there are two routes back. The first is automatic: after each 5 April, HMRC reviews PAYE records and issues a P800 calculation to anyone who has overpaid or underpaid. P800 letters are sent between June and March of the following year, and if yours shows a refund, you can usually claim it online and have the money paid within a few weeks, or wait for a cheque.10GOV.UK. Tax Overpayments and Underpayments
You don’t have to wait that long. HMRC’s online refund tool lets you check mid-year whether you’re owed money from employment, pensions, redundancy payments, savings interest, or several other sources.11GOV.UK. Check How to Claim a Tax Refund Better still, fixing the code itself during the year sorts the problem at source. Once the correct code is in place, your employer’s cumulative PAYE calculation automatically refunds any overpayment from earlier in the year through your next payslip, without you having to claim anything separately.
