Section 35d Deduction - For Preliminary Expenses

Section 35D of the Act was introduced to provide entrepreneurs with the facility to claim deductions for preliminary expenses. Preliminary expenses are expenses which the promoters of a company incur at the time of incorporating the company. Generally, preliminary expenses are disallowable on the ground that they are of a capital nature or incurred prior to the setting up of a business. However, to provide incentives to entrepreneurs who are spending their own money for incorporating a business enterprise, the Government introduced Section 35D of the

Income Tax Act. The present article provides an explanation of Section 35D.
