When does a Delaware C Corporation need to file a tax return?

I’m a CPA, Deloitte Tax alum, and I personally prepare 150+ DE C Corp tax returns a year.

You will need to file your DE C Corp tax return by 4/15 every year. You can also go on federal extension to 10/15. State extensions vary. If you’re running at a loss, its better to go on extension so that you have more time to review the previous year’s financials. I’ve seen plenty of startups rush to get their taxes in by 4/15, only to discover a few months later that they need to add in a few expense reimbursements for the founders. Then we have to do an amended return.

Measure twice, cut once!

***Also note that DE C Corps have to file the DE Annual Fee by 2/28 every year. This is a calc driven off of your cap table and assets, and is typically between $400-$4000 for a seed / Series A startup.


We are the experts at helping seed/VC-backed Delaware C-Corps with their accounting and finances!
