Business deductible expenses are costs that are legitimately incurred by businesses in the normal course of their operations and that can be used to reduce a business’s taxable income. These expenses include, but are not limited to, marketing and advertising costs, rent or lease payments for business premises, utilities such as electricity and phone lines, employee wages, vehicle operating costs, and insurance premiums. By deducting these expenses from a business’s tax bill, businesses can increase their profits and remain competitive in the market.
