What are the states that require special attention for annual audits of U.S. companies, and what are the states that do not routinely do annual audits on the anniversary of each year, and when exactly?

The annual audit includes
 1. renewal of relevant government documents, including the confirmation of directors and shareholders’ information and the management positions of the company.
 2. Registration of the registered address of the company; the annual inspection fee of the U.S. company is mainly composed of government fees, service fees, address usage fees, secretary service fees, etc., and also includes other necessary fees such as courier fees generated by the return mail of the file.

Annual audit: Most states have an annual audit, which is done before the incorporation date each year starting the following year, usually with a grace period of about one month. Failure to do so may result in government fines or irregularities in the company’s status.
 Some states have designated dates or periods for annual audits, frequently registered states such as
 Delaware C Corporation annual audit on March 1, LLC annual audit on June 1;
 Florida annual audit by May 1 each year;
 Texas by May 15 each year;
 New York every two years;
 Pennsylvania every 10 years, etc.
