1. Lower tax rate on profits of the corporation
Profits of a C corporation are taxed at a relatively low rate. The corporation is taxed at 15% on amounts up to $50,000.

Entities such as S corporations flow their profits through to the shareholder at the end of the year. Profits are then taxed at the higher personal rates.

2. Unlimited number of Shareholders
C corporations are not limited to a maximum number of shareholders as opposed to S corporations where no more than 75 individuals can own shares.

3. Not limited in the type of Shareholders
C corporation owners can be individuals, trusts, non-resident aliens, corporations, partnerships or LLC's. Owners of S corporation shares can only be individuals, estates or certain types of trusts.

4. Ability to choose a fiscal tax year
C corporations have flexibility in electing a fiscal tax year that best matches the company's business cycle. S corporations have a number of restrictions in choosing a year-end other than December 31.

C corporations can also use a delayed tax year to defer taxes. S corporations are required to make payments reflecting any tax deferral.

5. Expenses are deductible on the corporate level
Expenses like charitable contributions can be deducted. S corporations pass charitable expenses through to the owners, who might not be able to deduct them.

6. Use of Net Operating Losses
Federal Losses can be carried back or forward to other year's tax returns. This can generate tax refunds or offsets to future taxable income.
