A Tax Guide For C Corps

When it comes to starting a business, there are a lot of decisions to make. One of your biggest is which entity is right for your business. Once you’ve chosen an incorporation structure and established your entity, you’ll need to focus on one important topic: taxes. Each entity has its own tax filing requirements. Partnerships use Form 1065, LLCs file their taxes on their personal income tax return, S Corps use Form 1120-S and NPOs and sole proprietors have their own requirements.

Income tax and C corporations

Form 1120 is the tax form used by C Corporations and LLCs filing as a corporation to report profits and losses, tax deductions, credits and income. This form is also used to figure out the business’s tax liability. You can think of the 1120 form as the C Corp equivalent to the 1040 form. Or the 1099 tax for freelancers. C Corporations are taxed at a corporate rate set by the Internal Revenue Service (IRS). In most cases, C Corporations pay taxes on a quarterly basis. A quarterly tax calculator is just the tool for this. There are different types of Form 1120 for specific organizations. But Form 1120 is the only form you’ll need to worry about for a C Corp business.
