Massachusetts Corporate Tax Deadline 2025: What Happens If You Missed It?
Q: When were Massachusetts corporate tax returns due in 2025?
A: For C corporations that filed for an extension, the due date for Form 1120 was October 15, 2025. This is the standard extended deadline for calendar-year corporations. Many Massachusetts businesses rely on extensions to gather documents, finalize financials, or resolve bookkeeping issues. However, once this date passes, any corporation that has not filed is officially late.
Q: What happens if a corporation missed the 10/15/25 deadline?
A: Missing the deadline triggers automatic IRS penalties and accruing interest. The late-filing penalty for Form 1120 is generally 5% of the unpaid tax per month, up to a maximum of 25%. Even if your corporation owes nothing, failing to file can still create compliance problems and IRS notices. Interest also applies on top of penalties, which means the longer you wait, the more costly the mistake becomes.
Q: Can Massachusetts corporations get penalty relief?
A: Yes. The IRS allows corporations to request reasonable cause penalty abatement under certain circumstances. If your business can demonstrate valid reasons for missing the deadline—such as natural disasters, records destroyed, or major unforeseen events—you may qualify for relief. As enrolled agents, Drenen Financial Services can prepare the necessary filings and represent you directly before the IRS to request relief.
Q: What should you do right now if you missed the deadline?
