You put an employee’s tax code into your payroll software to work out how much tax to deduct from their pay throughout the year.

Tax code 1250L

The most common tax code for tax year 2019 to 2020 is 1250L. It’s used for most people with one job and no untaxed income, unpaid tax or taxable benefits (for example a company car).

1250L is an emergency tax code only if followed by ‘W1’, ‘M1’ or ‘X’. Emergency codes can be used if a new employee doesn’t have a P45

What Tax code 1250L Means

The numbers in an employee’s tax code show how much tax-free income they get in that tax year.

You usually multiply the number in the tax code by 10 to get the total amount of income they can earn before being taxed.

For example, an employee with the tax code 1250L can earn £12,500 before being taxed. If they earn £27,000 per year, their taxable income is £14,500.

What you need to do

When you take on a new employee, you normally work out their tax code by using their P45. The code will usually be made up of several numbers and a letter, such as 1250L.

You must report this information to HM Revenue and Customs (HMRC) using a Full Payment Submission (FPS) on or before your new starter’s first payday.

Before you can work out your new employee’s tax code and starter declaration, you’ll need to:

You usually need to update your employee’s tax code at the start of a new tax year. If the tax code changes during the year, HM Revenue and Customs (HMRC) will email you – you should update your payroll records as soon as possible.

What the letters mean in Tax Codes

Letters in an employee’s tax code refer to their situation and how it affects their Personal Allowance.

If your employee’s tax code has ‘W1’ or ‘M1’ at the end

W1 (week 1) and M1 (month 1) are emergency tax codes and appear at the end of an employee’s tax code, for example ‘577L W1’ or ‘577L M1’. Calculate your employee’s tax only on what they are paid in the current pay period, not the whole year.

Tax codes with the letter ‘K’

The letter K is used in an employee’s tax code when deductions due for company benefits, state pension or tax owed from previous years are greater than their Personal Allowance.

Multiply the number in their tax code by 10 to show how much should be added to their taxable income before deductions are calculated.

ExampleAn employee with tax code K475 and a salary of £27,000 has taxable income of £31,750 (£27,000 plus £4,750).

The tax deduction for each pay period can’t be more than half an employee’s pre-tax pay or pension.
