Details for Employed and Self Employed

To work out tax, National Insurance and Student Loan deductions for the Employed and Self Employed the UK Government's latest tax information from the April 2016 budget is used. Below are details of the figures used.

Income Tax

Standard Allowances
Personal Allowance 11,500
Overall income limit 100,000
Additional Allowances
Blind Allowance 2,320
Married rebate 844.50
Tax Bands
(on taxable income after allowances)
0 - 33,50020 %
33,500 - 150,00040 %
Over 150,00045 %

Income tax is calculated using your gross income - i.e. your salary from employment plus your profit from self-employment. There is a personal allowance below which you pay no tax - this is 11,500. Anyone earning more than 100,000 per year will have their personal allowance reduced by 1 for every 2 over that threshold until the personal allowance reaches zero. Your tax free personal allowance may be different from these standard allowances if your tax code instructs it to be different - see the section on tax codes below.

Additional allowances are available if you are registered as blind or are over 81 and married. The blind receive a further allowance of 2,320 and those over 81 and married receive a rebate, after other deductions, of 844.50. This rebate can be reduced, if your income is sufficient, to 326.

Tax bands are applied to taxable income (i.e. after the allowance has been deducted) so that as you earn more money, you pay a higher rate of tax. On the first 33,500 of taxable income, you pay 20% tax. Between 33,500 and 150,000 you pay 40% tax, and above 150,000 you pay 45% tax.

Tax codes are used by HRMC to tell your employer that you should have a different personal allowance from the standard allowances listed above. This often happens because you are receiving other taxable benefits from your employer, such as private healthcare or a company car. Usually, this has the effect of reducing your allowance and therefore increasing the tax you pay. Most tax codes indicate the new personal allowance with a number which should be multiplied by 10 and then have 5 added to give the new allowance. The tax code 1150L would give the standard personal allowance of 11,500.

From April 2016, tax codes can start with the letter S, which indicates that you pay the Scottish Rate of income tax. At the moment, the total amount of income tax paid is the same as for non-Scottish tax payers, but a proportion of the tax goes directly to the Scottish government rather than to the UK government.

National Insurance

Class 1 Code A
0 - 157 / week0 %
157 - 865 / week12 %
865 and above2 %
Class 2
0 - 5,965 / year 0
5,965 and above 2.80 / week
Class 4
0 - 8,0600 %
8,060 - 43,0009 %
8,060 and above2 %

National Insurance can be complicated if you are both employed and self-employed, as income from self employment has National Insurance deducted at a different rate from income from employment. National Insurance is separate from income tax but is also calculated depending on how much you earn. Class 1 contributions are based on your income from employment only - not self-employment. Conversely, Class 2 and Class 4 contributions are based on your profits from self-employment, not your employed income.

You may not pay any National Insurance - for example, if you have reached state pension age. If this applies to you, the "No NI" option will mean that none of the different National Insurance Contributions described below will apply to you and NI will be 0.

Employment National Insurance - Class 1

Most employees will have NI Code A applied, with the band A rates and thresholds applied. If your total income, before tax, is less than 157 per week you will pay no National Insurance contributions. Between 157 and 865 per week you will pay 12%. Above 865 per week you will pay 2%.

Self Employment National Insurance - Class 2 and Class 4

Class 2 National Insurance is charged at a flat rate of 2.80 per week. Previously this was collected throughout the year but now it is paid along with your other tax when you do Self Assessment. If your profits for the year are under 5,965, you do not need to pay Class 2 contributions - however, you may choose to do so on your tax return to ensure you remain eligible for NI-related benefits, such as the state pension.

Class 4 National Insurance depends on the annual profits of your self-employment. Below 8,060, you make no contributions. Above 8,060 and up to 43,000 you pay Class 4 at a rate of 9%. Above 43,000 you pay additional Class 4 contributions at a rate of 2%.

However, if you are both Employed and Self Employed, Class 4 contributions can get more complicated. Because those who are employed and self employed at the same time would otherwise pay a lot of National Insurance at the normal rates (12% for employment and 9% for self-employment), HMRC will take into account the amount of Class 1 National Insurance you paid through your employment when working out the Class 4 National Insurance you owe. You used to have to apply for "deferment" of Class 4 NICS but this is no longer necessary.

If you did not apply for deferment in time, it is possible to apply for a refund of overpaid National Insurance, although not normally until the February after the end of the relevant tax year (e.g. February 2017 for the 2015 / 16 tax year). As mentioned above, details of National Insurance refunds are on the HMRC website.

Employer National Insurance

Employer's NI
0 - 8,1120 %
8,112 and above13.8 %
Employers NI credit 3,000

If you have a limited company, the company will have to pay employer's National Insurance contributions on any salary you pay yourself. Employer's NI is calculated at a rate of 13.8 % of any salary over 8,112. Introduced from April 2014 is an NI credit of 3,000 for qualifying companies to reduce their NI bill.

Student Loans

Plan 1
0 - 17,7750 %
17,775 and above9 %
Plan 2
0 - 21,0000 %
21,000 and above9 %

There are now two ways to repay your Student Loan. If your course started before 1st September 2012, you will repay under "Plan 1", which is the same as the previous repayment method. If your course started on or after 1st September 2012, "Plan 2" repayment applies to you. Plan 1 repayments are made at the rate of 9% of all income (i.e. employment income plus self-employment profit) over the income limit of 17,775. Plan 2 repayments are made at the rate of 9% of all income (i.e. employment income plus self-employment profit) over the income limit of 21,000. These deductions will continue to be made until HMRC receive instruction from the Student Loans Company that you have paid off the full amount of your loan. In some cases it is possible that you might continue to have deductions made even after you have paid of your loan - the Student Loans Company will normally write to you if this is likely to happen.

Pension Contributions

Pension contributions are calculated as the percentage you entered of your base employment salary (i.e., not including overtime). This is deducted from your take-home pay, but as you do not pay tax on pension contributions it is also deducted from your taxable income, reducing the tax that you pay. Pension options do not affect calculations of self-employment income.

Corporation Tax

Corporation Tax Rates
Main rate20 %

Corporation tax is due on the profit of limited companies. Before April 2015, if the company's profit was below the "Small profits limit" there was a lower rate of tax applied than if it was above this limit and the "Main rate" applied. From April 2015, however, the small profits rate and the main rate were made the same, so all Corporation Tax is assessed at the main rate of 20%.

Tax on Dividends

Dividend Tax Rates
(taxed after other income)
0 - 33,5007.5 %
33,500 - 150,00032.5 %
Over 150,00038.1 %

If you have a limited company, any money left over after expenses, your salary, Employer's NI and Corporation Tax will be available for you to take as a dividend.

Dividends are taxed according to the normal income tax thresholds, but at different rates (the rates are different because Corporation Tax has already been taken off this income). Dividends are taxed after other income - so your tax-free personal allowance would be applied to your salary first, and any remainder used for dividends. Similarly, if you have other taxable income it will "use up" the lower rates of tax before the dividends can use the remainder. You do get 5,000 of dividends tax free, and then on the first 33,500, you pay 7.5% tax. Between 33,500 and 150,000 you pay 32.5% tax, and above 150,000 you pay 38.1% tax.
