Income Tax and National Insurance
As the Director of your own Contractor Limited Company you have the right to decide how much you pay yourself in salaried income and how much you receive in company dividends (where outside IR35). National Insurance costs can be minimised by taking a low salary, a small expense package and a large proportion of income in company dividends but this is not possible where caught by IR35. If caught by IR35 you will need to take contract income in the form of salaried income on which full income tax and class 1 national insurance payments are due.What levels of Income Tax and National Insurance is applied to salary?
In the UK income from employment is taxed at source and paid directly to the government by the employer. The Pay as You Earn (PAYE) system is the government’s means of collection. Before a net salary payment can be made Income Tax and Class 1 National Insurance must be deducted. There are two types of Class 1 National Insurance payable:- Class 1 Employees National Insurance
- Class 1 Employers National Insurance
Employees National Insurance is payable by an employee on salaried income. It is levied at a rate of 11% between the primary threshold, £5,460 (annual) and the upper earnings limit, £40,040. Any Income above the upper earnings limit is taxed at a rate of 1%. Therefore a ‘cap’ is in place to reduce the level of national insurance paid by high earners.
Employers National Insurance is payable by the employer on an employees salary and benefits. Benefits may include a company car, health club membership etc but are unlikely for freelance contractors running Limited Companies. Employers National Insurance is levied at a flat rate of 12.8% above the secondary threshold of £5,460 (annual); there is no upper limit or ‘capping’.
For limited company contractors the biggest National Insurance saving will be on Employers National Insurance. Unlike Employees National Insurance which involves a cap at the upper earnings limit, Employers National Insurance is uncapped.
