Reporting Corporate Income Reconciliations (Form 1120) in TaxAct
1
If you're filing taxes on behalf of a corporate entity, you may need to reconcile that entity's accounting income (also known as "book income") with its taxable income. The IRS uses Schedule M-1 of Form 1120 for reporting such reconciliations.


You can use TaxAct to report these income reconciliations.

  1. Sign in to your TaxAct account, then click the My Tax Returns tile.
  2. Locate the relevant return, then click Open Return in the Actions column for that return.
  3. In the left navigation bar, click Federal.
  4. In the Federal Quick Q&A Topics panel, click Reconciliation of Income.
  5. Continue with the interview process to enter all of the appropriate information.
