FAQs
Your Top Questions, Already Answered.
What documents are required for corporate tax filing?
For business tax filing, you’ll need financial statements (profit & loss and balance sheet), bank and credit card statements, payroll reports, prior-year returns, ownership details, and depreciation schedules. These documents help your business tax preparer complete an accurate business tax return.
When is the filing deadline for Form 1120 and Form 1120-F?
The Form 1120 filing deadline for most C-corporations using a calendar tax year is April 15.
For Form 1120-F, the deadline depends on the company’s presence in the U.S.:
- April 15 if the foreign corporation maintains a U.S. office or place of business.
- June 15 if the foreign corporation does not have a U.S. office.
