PAYE codes: 1250L,1185L…K487…S1185L. What do they all mean? The financial cyphers applied to your wage slip can be daunting. Consequently, understanding your Tax Code can save you £100s and make life a whole lot simpler. This handy guide gives you back control to ensure you are paying the correct amount of Income Tax and National Insurance.
PAYE means “Pay As You Earn”. Before you even get paid, income tax is already deducted ‘at source’. Because of this, it is the way most employees pay Income Tax and National Insurance.
Crucially, it’s easy and tax is collected automatically ‘at source’ as you earn.
This is in contrast to “Self Assessment” which is used by the self-employed. In this instance, the onus is on the individual (or their accountant) to calculate and pay tax once or twice a year, which can take up a whole lot of time
A tax year runs from April 6th one year to 5th April the next.
What is Self-Assessment?
Self-Assessment is a form of tax return. If your only income is from your salary, wages or pension, you do not need to file a tax return as this is usually done by PAYE
However, there are exceptions:
You earned over £1,000 as a sole trader / self-employed
If you are a partner in a business partnership
Have un-taxed income from:
tips and commission
savings, investment or dividends (excludes Premium Bonds which are tax-free)
Have an annual income of over £100,000
How does PAYE work with Pensions?
If you’re retired, PAYE can also be used to deduct tax from pensions. In this scenario, HMRC (ie, the ‘tax man’) will instruct your pension provider to deduct Income Tax directly, rather than have to manually calculate it each year. Your income will need to be above the thresholds detailed below.
What is a P60?
Each year, after April 5th, a P60 automatically gets issued to you. You’ll often find it accompanies your April payslip from your employer.
Your P60 shows things such as:
Earnings during that tax year
What you’ve paid in Income Tax
Your National Insurance contributions
How is PAYE calculated?
The amount of PAYE tax you pay is based on your income and your eligibility for the Personal Allowance.
This calculation is reflected in your Tax Code, which is a combination of letters and numbers that is used by HMRC to tell your employer or pension provider how much tax to deduct from your pay.
If you have just started a job, your employer might not be able to obtain the correct tax code in time. If this happens, an Emergency Tax Code will be applied.
The most common tax code for 2020/21 is 1250L. The ‘1250’ refers to the fact you can earn £12,500 without being taxed. Typically, this code is used for most people with a single job and no additional untaxed income (such as interest on savings), unpaid tax or taxable benefits (for example a company car).
What is a tax code?
Tax codes are all about your taxable allowance and are made up of numbers and letters. Importantly, they each mean different things. Let’s use 1250L as an example:
Numbers – show your allowance of income that you can earn which you are not taxed on. In our example, the first £12,500 is not taxed.
Letters – refer to the type of allowance you get. In the example above, ‘L’ means your eligible for the basic personal allowance.
Taxable income is based on your personal circumstances and Government legislation at the time. For example, the basic Personal Allowance for the tax year 2018/2019 was £11,185. In 2019/20 it rose to £12,500. This means you can earn up to that threshold before you start paying tax. As the allowance rises you will pay less tax and so be better off.
If you earn over £100,000 per year your personal allowance reduces by £1 for every £2 you earn. This means by the time you get to £125,000 your personal allowance is removed.

How much PAYE tax should I be paying?
Income Tax is based on your income and calculated in four ‘bands’.
The first band is your Personal Allowance and is tax-free. This means you do not pay tax on any income up to your Personal Allowance threshold.
The second band is the Basic Rate of tax. The PAYE system will deduct 20% of any income between the lower and upper thresholds (check the table below). About 80% of employees fall into this category, according to the BBC.
The Higher Rate is the third band and applies the same principle. Crucially though, tax is now taken at 40% of any income within the thresholds. About 13-14% of all UK employees fall into this category.
The final threshold is the Additional Rate if you’re lucky enough to worry about such things. For the privilege, you are going to lose an eye-watering 45% of any income above this threshold.
What are the PAYE Tax Bands?
Here are the current four Tax Bands and their thresholds for the current and next tax year.
2019/20 & 2020/21
£0 – £11,850
£0 – £12,500
Basic rate (20%)
£11,851 – £46,350
£12,501 – £50,000
Higher rate (40%)
£36,351 – £150.000
£50,000 – £150,000
Additional rate (45%)
What is National Insurance?
By paying National Insurance at source, you’re building your entitlement to state benefit such as the state pension. Importantly, remember that NI is in addition to the tax bands above.
12% of any income between £162 and £892 per week
2% for any earnings above £892 per week
These rates change in April 2019 to 12% on any income between £166 and £962 per week and 2% for anything above this.

What are emergency Tax Codes?
If HMRC cannot supply the correct tax code to your employer, an Emergency Tax Coe will be applied.
They can, however, be pretty horrific, costing you up to 50% of your wage.
The good news is that this is usually a temporary issue and occurs when starting a new job part way through a tax year.
If your tax code ends in these suffixes, you can be fairly sure you’ve got an Emergency Tax Code on your hands:
For example, 1185L-W1 is a typical Emergency Tax Code.
Your employer and HMRC will usually quickly resolve an Emergency Tax Code, automatically adjusting any overpaid or underpaid tax. As always though, it’s best to be proactive by checking up on these things and telling HMRC about your new employer.
You will stop paying any Emergency Tax Code at the start of a new tax year (April 6th). After that, your employer will then start taxing your salary as normal. You can claim back any overpaid tax from HMRC.
How to claim back overpaid tax?
HMRC will often automatically issue repayment if you’ve overpaid tax such as at temporary Emergency Tax code. You may, however, need to manually request an adjustment and repayment if you haven’t been notified by HMRC via a P800 calculation.
