I dreaded cancelling my first LLC for an entire year. In the end, it wasn't nearly as complicated as I had imagined. This post outlines the steps you should follow to shut down your Stripe Atlas LLC.
First, you'll need to square away your tax obligations. Let's say it's January 5, 2000. You paid the \$300 franchise tax to Delaware on March 1 of 1999. That payment was for the existence of your LLC in 1998. Before you cancel your LLC, you need to pay \$300 for its existence in 1999, and another \$300 for its existence in the first 5 days of 2000 (oof).
Once you've paid up, the next step is to download and fill out a certificate of cancellation. The form itself is dead simple. If you need the date of formation of your LLC or your file no., they're both stamped on your Certificate of Formation.
If you have questions, you can call the number on the certificate. I had to call them, and it was great. A friendly human picked up and answered my dumb questions.
When you're done, you can upload the filled certificate to the Delaware Department of Commerce website here. The fee to cancel a LLC is $200, and the website accepts a credit card.
With your LLC cancelled, you can move along to closing your other accounts. It's easy to shut down your Azlo account--just call the number, and they'll email you to confirm. Then you can tell Stripe to stop renewing your registered agent via their web interface, and finally close your Stripe account with the close account button.
Voila, you're done!
