If you own a Partnership or Multi-Member LLC, your federal tax return (Form 1065) is due on March 15, 2026. Not April 15. March 15.
Miss this deadline without filing an extension, and the IRS imposes a penalty of $220 per partner, per month — with no cap on the number of months. For a 3-member LLC that files just 2 months late, that’s $1,320 in avoidable penalties.
Here’s the good news: filing an extension (Form 7004) gives you until September 15 to submit your complete return — penalty-free. But the extension itself must be filed before the March 15 deadline.
Don’t scramble to file a rushed return. Don’t risk errors that trigger audits. A properly filed extension gives you the breathing room to get your K-1s right, coordinate with your partners, and ensure every deduction is accounted for.
You still have time — but not much.
When you file your extension through Simplify My Numbers, you’re not just avoiding penalties — you’re getting a head start on saving money.
Here’s what’s included:
Why do we include the strategy session? Because every time we review a partnership’s filing data, we find optimization opportunities — restructuring distributions, adjusting guaranteed payments, planning for estimated taxes. We’d rather show you what’s possible than let those savings slip through the cracks.
Our team brings over 96 years of combined tax experience. We don’t just file paperwork — we build tax strategies that protect your bottom line.
Fill out the form below. One of our tax professionals will contact you within 24 hours to confirm your details and get your extension filed — before the deadline.
