Corporate Tax Filing FAQs
Have questions about your taxes? Our experts are here to help you understand deductions, refunds, and compliance — so you can file with confidence and peace of mind.
When are corporate tax returns due?
C-Corporations (Form 1120) are due April 15, or the 15th day of the fourth month after the fiscal year end. S-Corporations (Form 1120-S) are due March 15. Extensions are available for six months.
What is the difference between C-Corporation and S-Corporation?
A C-Corporation pays corporate income tax directly, while an S-Corporation passes income and losses through to shareholders’ personal returns. We help you determine which structure offers the greatest tax advantage.
Do corporations pay estimated taxes?
Yes. C-Corporations must make quarterly estimated payments if they expect to owe more than $500 in tax for the year. We calculate and schedule these payments for you.
Can you file consolidated corporate returns?
Yes. We prepare consolidated returns for corporate groups under common ownership, ensuring all entities are properly reported.
How do you handle depreciation and credits?
We manage fixed-asset schedules, apply Section 179 and bonus depreciation, and identify eligible credits such as R&D and energy incentives.
Can you assist with multi-state corporate taxation?
Absolutely. We prepare and reconcile filings for corporations that operate or have nexus in multiple states, ensuring accurate apportionment of income and compliance everywhere you do business.
What if my corporation needs to amend a return?
We handle amendments via Form 1120-X or 1120-S amended filings, correcting errors and reclaiming missed deductions.
Do you help new corporations set up correctly for taxes?
Yes. We assist with EIN registration, entity classification elections, and establishing accounting systems aligned with IRS requirements.
