It is a tax levied on the profits of incorporated entities, such as corporations and limited liability companies (LLCs). Understanding CIT rates, deductions, and credits is essential for businesses to minimize their tax liability and maximize their profits.

$10,000,000 - $18,333,333	45%
Over $18,333,333	48%

Section 2: Deductions and Credits

Businesses can reduce their taxable income by taking advantage of various deductions and credits. Common deductions include:

corporate income tax

Business expenses: Expenses directly related to the operation of the business, such as salaries, rent, and utilities.
Depreciation: Allowances for the wear and tear of assets over time.
Interest expenses: Payments made on business loans.

CIT credits provide direct reductions in tax liability. Common credits include:

Businesses must file Form 1120, U.S. Corporation Income Tax Return, annually. The deadline for filing is April 15th (June 15th with an extension). Estimated tax payments are required throughout the year using Form 1120-ES, Estimated Tax for Corporations.

Section 4: State Corporate Income Taxes

In addition to federal CIT, most states also impose their own CIT rates. State CIT rates can vary significantly, ranging from 0% to 12%. Businesses operating in multiple states must navigate the complexities of multistate taxation.
