Understanding your tax code and NI contribution letter

Tax is calculated based on your tax code and tax thresholds.

Your tax code is usually notified to UCL through a P45, P46 or Starter Declaration or via HMRC. If your previous employer has issued you with a P45 please ensure you hand it to payroll. If you do not have a P45, please complete a P46 or Starter Declaration and forward this to Payroll Services. The P46 or Starter Declaration is available in the Forms section of the Payroll Services website.

Tax Codes

A tax code is usually made up of a set of numbers and a letter. There are many different tax codes in operation for individuals, but below is a brief example of some of the most common tax codes:
Where your tax code consists of a number and then a letter, this will express the amount of free pay you have available before tax is assessed against your income. For example, tax code 1000L means that you can earn £10000.00 per annum before paying any tax. Just replace the ending letter with a 5 to understand how much you can earn per year before payment of tax. If your tax code is different from numbers then a letter, please contract Payroll services who will be happy to discuss your individual coding and what this means for you.

1060L - This is the emergency and standard tax code for tax year 2015/2016. Most employees will correctly be on this code

BR - This is basic rate tax code. Typically this is used for employees that have other sources of income including payments from an Occupational  Pension Scheme

0T - This is a code that means you have no allowances taken into consideration. It is usually used if we have received no notification of a tax code (via P46 or Starter Declaration/P45 or HMRC). 

K(followed by numbers) – A K code is where your personal allowances are lower than deductions due for benefits or outstanding tax for prior years as advised by HMRC. We will only operate this code if advised via a P45 or directly through HMRC. If you are unsure why you have a K code you should contact HMRC .

Month One Indicator

If your tax code is followed by a letter "X" or "1" this means that tax will be assessed against your taxable earnings in that month. Otherwise tax will be accessed on a cumulative basis. A cumulative basis will take into account your earnings for the entire tax year before assessing how much tax should be paid this period. The Month One indicator mean that tax will be calculated solely on your earnings this period, and will not assess this against your earnings and tax paid to date during the tax year.

NI contribution Letter

This dictates the % of National Insurance you pay on your contributions. Examples of common National insurance contribution letters are as follows:

A – Standard Rate NI. This is paid if you are not in a UCL pension scheme. Employees pay 12% and then 2%

D – Contracted Out Rate – Paid where you are in a UCL pension scheme. Employees pay 10.6% then 12% and then 2%

C – For employees who have reached state retirement age. No NI is due.

NI Thresholds

The percentages above are payable where earnings have reached the levels below:

For tax year 2015/16 the monthly amounts are:

£0 - £676 = No NI Due

£676 - £3337 = Apply relevant %

£3532 - £3337= 12% NI due

£3532 and over = 2% NI due

The NI contribution letter dictates the amount of NI payable. If you are on a different NI contribution letter, and wish to find out the % that is payable in your individual circumstance, please contract Payroll Services who will be happy to advise.
