As an employee, what are my tax deductible expenses?

The two main tax deductible expenses for an employee are:
A maximum of KES 20,000 per month as an employee pension contribution, including NSSF, paid to a pension scheme registered with the KRA and the Retirement Benefits Authority;
A maximum of KES 25,000 per month in mortgage interest (and not principal) paid by an employee who used such home loan to purchase/construct a house in which the employee lives in.
