The 1006L tax code tells your employer or pension provider to let you earn £10,060 a year before deducting any income tax, with the “L” confirming you get the standard personal allowance. It was the default code for most employees in 2014–15. On a current payslip it means HMRC has reduced your tax-free amount below today’s standard £12,570, and it is worth checking why.
What the Number and Letter Mean
Every PAYE code has two parts. The number is your annual tax-free allowance with the last digit dropped, so 1006 stands for £10,060. Your employer multiplies the number by ten to work out how much of your pay to shield from tax across the year.1GOV.UK. Tax Codes: What Your Tax Code Means
The “L” is the most common suffix in the system. It simply means you qualify for the standard personal allowance and don’t have any unusual circumstances that call for a different letter.1GOV.UK. Tax Codes: What Your Tax Code Means
Is 1006L a Historical Code or a Current One?
1006L was the standard code for the 2014–15 tax year, when the personal allowance sat at £10,060. Since then the allowance has climbed to £12,570, making 1257L the default for anyone with a single job, no untaxed income, and no taxable employment benefits.2GOV.UK. Understanding Your Employees Tax Codes: Overview The government has frozen the personal allowance at £12,570 until at least April 2031, so 1257L is likely to remain the standard for several more years.3GOV.UK.

So if 1006L appears on an old payslip, P60, or P45 from 2014–15, that is exactly what you would expect to see. If it appears on a current payslip, something is chipping away at your allowance and bringing it down from £12,570 to £10,060.
Why You Might Have 1006L Today
HMRC lowers your code number when it needs to collect tax on income or benefits that aren’t taxed at source. Common reasons for a reduced allowance include:
- Taxable employment benefits such as a company car or private health insurance. Your employer provides them, HMRC treats their value as extra income, and your code is trimmed so the tax comes out of your regular pay rather than landing as a lump sum.4GOV.UK. Expenses and Benefits for Employers
- Untaxed income like savings interest above your personal savings allowance, rental income, or side earnings outside PAYE.
- Underpaid tax from a previous year, which HMRC often recovers by reducing your current code.
- The state pension, which is taxable but paid without tax deducted, so HMRC adjusts your employment code to cover it.
- The High Income Child Benefit Charge, if you or your partner earn over £60,000 and claim Child Benefit.
There is also a common reason for a much lower code that catches high earners. If your adjusted net income exceeds £100,000, your personal allowance shrinks by £1 for every £2 you earn above that threshold, and disappears entirely at £125,140.5GOV.UK. Income Tax Rates and Personal Allowances The taper produces an effective marginal rate of 60% between £100,000 and £125,140, because you lose allowance while being taxed at 40%. Pension contributions or Gift Aid donations can sometimes bring your adjusted income back below £100,000 and restore some of the allowance.
HMRC sets all of this out on a P2 coding notice, which shows your full personal allowance, every deduction applied against it, and the resulting code number.6HM Revenue & Customs.

How Tax Is Calculated on 1006L
With a 1006L code, the first £10,060 of your annual earnings is tax-free. Everything above that gets taxed at the rate for the relevant band. The code itself doesn’t decide which rate you pay; it only sets the point where tax starts.
Take someone earning £30,000 a year. The payroll system subtracts the £10,060 allowance, leaving £19,940 taxable. For the 2025–26 tax year in England, Wales, and Northern Ireland, the bands are:5GOV.UK. Income Tax Rates and Personal Allowances
- Basic rate (20%): taxable income up to £37,700
- Higher rate (40%): £37,701 to £125,140
- Additional rate (45%): above £125,140
The whole £19,940 in the example sits inside the basic rate band, so the annual tax bill is £3,988. Payroll spreads that across the year, taking roughly £333 a month or £77 a week.
One boundary worth flagging: Scottish and Welsh taxpayers have their own arrangements and their codes carry an S or C prefix rather than a plain number and L suffix, so a straight 1006L on a current payslip reflects the rates and bands used in the rest of the UK.1GOV.UK.

How to Check and Correct the Code
You can view your current tax code, see how it was calculated, and report changes through your personal tax account on GOV.UK or the HMRC app.7GOV.UK. Check Your Income Tax for the Current Year The online service lets you update your income details, report new or ended benefits, and tell HMRC about changes in your circumstances that affect the code.8GOV.UK. Tax Codes: Why Your Tax Code Might Change
If a deduction on your P2 no longer applies, updating your details online is usually the fastest fix. HMRC reviews the change and, if it agrees, issues a new P2 to you and your employer. Your employer adjusts your deductions from the next available pay run, and the change typically shows up within one to two pay cycles. The income tax helpline covers situations the online service can’t handle.
Getting a Refund If You’ve Overpaid
If the wrong code has left you paying too much tax, HMRC should eventually send a P800 tax calculation showing what you’re owed. If it doesn’t arrive and you’re sure you’ve overpaid, you can claim the refund directly through GOV.UK.9GOV.UK. Tax Overpayments and Underpayments
For the current tax year, refunds are usually handled by correcting your code so less tax comes out of your remaining paychecks, which returns the money over the rest of the year. For previous years, HMRC generally sends a cheque or pays the refund into your bank account. Claims can go back four tax years, so if you suspect the code has been wrong for a while, it is worth acting rather than waiting.
