In California both S-corporations and C-corporations pay corporate income tax using this form.
Quarterly estimated tax payments should be mailed to the Franchise Tax Board.
|
|
| Because of the minimum annual tax (franchise fee), all corporations must use this form,
even if they didn't have a quarterly net income or paid their net income out as salaries
or bonuses. |

For the first year, you pay the tax rate (1.5% for S-corporations
or 8.84% for C-corporations) times your corporation's net taxable income.
In future years to avoid penalties, you must pay estimated tax payments equal to 95% of your
actual tax bill or 100% of last year's tax bill, whichever is less. Make sure that:
- 25% of your estimated tax bill is paid by April 15
- 50% of your estimated tax bill is paid by June 15
- 75% of your estimated tax bill is paid by September 15
- 100% of your estimated tax bill is paid by December 15
