C-Corporation Tax Preparation (FORM-1120)

Form 1120 is your annual corporate tax return. Form 1120 also includes Schedule C. Form 1120 requires basic information about the corporation, such as the employer Identification number, a list of any deductions and compensation to your officers or board of directors. Form 1120 also includes lists of other schedules that may or may not apply to your business. For example, Schedule A includes the cost of goods sold, and Schedule K lists information about your corporation, such as your accounting and business type.


At EJ Tax & Immigration Services, our firm assist clients such as Corporations that can generally electronically file (e-file) Form 1120, related forms, schedules, and attachments, Form 7004 (automatic extension of time to file) and Forms 940, 941, and 944 (employment tax returns). If there is a balance due, the corporation can authorize an electronic funds withdrawal while e-filing. Form 1099 and other information returns can also be electronically filed. The option to e-file does not, however, apply to certain returns.
