The IRS charges 5% of unpaid taxes per month — up to 25% of your total unpaid balance — starting the day after the deadline.
Interest on unpaid taxes compounds daily from April 15 onward — even if you eventually file. It adds up fast.
Netfintax can file your return or secure a 6-month extension today — stopping penalties before they start.
All domestic C-Corps with a calendar tax year must file Form 1120 by April 15 — or file Form 7004 to extend.
Sole proprietors, freelancers, and independent contractors file Form 1040 with Schedule C by April 15.
Single-member LLCs taxed as sole proprietors report on Schedule C — same April 15 deadline as individuals.
An extension gives you until October 15 to file — but taxes owed must still be paid by April 15 to avoid interest.
