C-Corporations must pay corporate income tax deposits on their net income. The tax is paid quarterly online using the EFTPS system.
S-corporations do NOT pay this tax or use these forms.
Some corporations avoid corporate taxes - and this form - by paying all their profits in salaries and bonuses. If you do this, remember to pay employment taxes on salaries and bonuses.

How to complete the form
Steps and what to do
1. Estimate the corporation's year-to-date net income. If you are unsure what makes up net income, look at the front page of IRS 1120.
Estimate the corporation's net income for the remainder of the year.
Add the two and put the total on line 1 of 1120-W.
2-11. Multiply the first $50,000 of line 1 by 15%; the next $25,000 by 25%; and the next amount up to $9,925,000 by 34% and any remaining amount by 35%.
12-14. These lines are for excess tax if you are a personal service corporation or had net taxable income over $100,000.
15-22. Subtract any expected tax credits to calculate total estimated tax on line 22.
Under $500 in tax?
If your total year's tax is under $500, you do not have to make quarterly payments. If it is more than $500, you must pay 100% of your tax through quarterly estimated tax payments. In future years, small corporations may pay 100% of last year's tax. Large corporations can use last year's tax to estimate their first quarter's payment only.
