The levy will be charged at a rate of 0.5% of your annual pay bill. You will have a levy allowance of £15,000 per year to offset against the levy you must pay. This means you will only pay the levy if your pay bill exceeds £3 million in a given year.
The levy allowance will operate on a monthly basis and will accumulate throughout the year. This means you will have an allowance of £1,250 a month. Any unused allowance will be carried from one month to the next. For example, if your levy liability in month 1 is £1,000 you will not pay the levy and your allowance in month 2 will be £1,500.
If you have some unused allowance in a month, but paid the levy previously in the tax year, you can receive a credit which you can use to offset against your other Pay as You Earn (PAYE) liabilities. The credit will also reduce the amount of levy paid.
This example uses an employer with an annual pay bill of £5,000,000
Levy sum: 0.5% x £5,000,000 = £25,000
Subtracting levy allowance: £25,000 - £15,000 = £10,000 annual levy payment
