Tax extension guides
Plain-English explanations of IRS extension deadlines, penalties, and how the forms work — so you can file with confidence.
Tax extension deadlines
When to file Form 7004, 4868, and 8868 by entity type — and what dates the extension moves you to.
Failure-to-file vs. failure-to-pay penalties
How IRS late penalties work, the difference between them, and how an extension helps you avoid the bigger one.
LLC tax extension
Which form your LLC uses based on how it's taxed — Form 7004 for most, Form 4868 for single-member LLCs.
S-corp tax extension
S corporations file Form 7004 to extend Form 1120-S — who files, the deadline, and how to e-file.
Partnership tax extension
Partnerships and multi-member LLCs file Form 7004 to extend Form 1065 by six months.
Nonprofit tax extension
Tax-exempt organizations file Form 8868 to extend a 990-series return — not Form 7004.
