Where an employee enjoys a benefit, advantage or facility of whatsoever nature in connection with employment or services rendered; the value of such benefit should be included in the employee's earnings and charged to tax.

Sometimes employers provide loans to their employees and charge an interest lower than the prescribed rate. This becomes a benefit to the employee, for which the employer needs to file and pay Fringe Benefit Tax.

The difference between the prescribed rate and the employer's loan rate is chargeable to tax, on the employee. The taxable value of fringe benefit tax is the difference between the market interest rate and the actual interest paid on the loan. 

Example:

Ken gets a loan of Kshs. 3,000,000

Loan amount:  Kshs.3, 000,000

Interest charged: 3%

Market Interest rate for the month: 9%

Fringe Benefit is (9% - 3% = 6%) = Kshs.3, 000,000 x 6% =180,000 p.a   

i.e.   Kshs. 15,000   per   month.

Fringe   Benefit   tax   payable   by   employer   is   Kshs.   15,000   x   30%

  =  Kshs. 4,500/-  for the month

This is a tax on loans to employees.

When an employer provides a loan to an employee and charges interest below the prescribed rate of interest, then the difference between the prescribed rate and the employer's loan rate is a benefit from employment, that the employee should pay tax for.

This is type of tax is called Fringe Benefit Tax
