Rates and thresholds for employers 2017 to 2018

Use these rates and thresholds when you operate your payroll or provide expenses and benefits to your employees.

Unless otherwise stated, the figures quoted apply between 6 April 2017 and 5 April 2018.

PAYE tax and Class 1 National Insurance contributions

You normally operate PAYE as part of your payroll so HMRC can collect Income Tax and National Insurance from your employees.

Your payroll software will calculate how much tax and National Insurance to deduct from your employees’ pay.

Tax thresholds, rates and codes

The amount of Income Tax you deduct from your employees depends on their tax code and how much of their taxable income is above their Personal Allowance.

Use the SSP calculator to work out your employee’s sick pay, or use the following rates.
