Annual State 100 Tax Return - C Corporation Go to topics
Your corporation's taxable income is reported to the state with form 100. It is virtually identical to IRS 1120. You should have paid quarterly state tax deposits using 100-ES. Any balance due for state taxes should be paid with form 100.
After you have paid state and federal taxes, you can distribute profits to your shareholders (called dividends). Your corporation and shareholders must report dividend income using IRS 1099-Div to the federal government. This information is automatically sent to the state. Shareholders must pay taxes on these dividends on their annual California 540 tax returns.
