No. 2: Annual business renewals due Dec. 31. Do it or lose it.

All registered businesses, including nonprofits, must renew their filing each calendar year — for most businesses there is no charge. This can be done by mail or online. Businesses required to file include corporations, limited liability companies (LLCs), partnerships and nonprofits. Failure to renew will result in dissolution. Do this to reserve or keep your business name, too!
