How to Choose a Bookkeeper in Mississippi (2026)

Choosing a bookkeeper in Mississippi comes down to three checks you can do in an afternoon: the firm's registration, any CPA license it claims, and a written fee with a close date. The third is the one most Mississippi firms leave to a call, since only 1 of the 34 we list put a price on their sites.

What a Mississippi bookkeeper keeps track of

A Mississippi bookkeeper keeps the records behind the filings below. Which of them reach your business turns on your entity, your sales, your payroll and the schedule each agency sets, so read this as general information rather than tax advice.

• Sales and use tax. Mississippi sets your sales and use tax filing frequency by how much you remit in a year. Under $600 means annual returns, $600 to $3,599 means quarterly, and more than $3,599 means monthly. Returns are due by the 20th day after the reporting period ends.

• Income tax withholding. Withholding returns are due the 15th day of the month after the period. The Department of Revenue tells you your filing status. Generally, an average liability of $300 or more a month means monthly returns, and smaller liabilities may file quarterly. Source: Mississippi Department of Revenue, checked September 26, 2026.
• Unemployment wage reports. Quarterly wage reports and unemployment taxes go to the Mississippi Department of Employment Security by the last day of the month after each quarter: April 30, July 31, October 31 and January 31. A due date on a weekend moves to the next business day. Source: Mississippi Department of Employment Security, checked September 26, 2026.
• Annual report. For-profit corporations and LLCs file an annual report with the Secretary of State between January 1 and April 15. Nonprofit corporations have until May 15. All annual reports are filed online, and a missed report can lead to administrative dissolution. Source: Mississippi Secretary of State, checked September 26, 2026.
• CPA title. Mississippi law makes it unlawful for anyone without a CPA license from the State Board of Public Accountancy to use the title certified public accountant, or letters or words that suggest it, apart from narrow exceptions such as a practice privilege.

How to check a Mississippi firm yourself

Any firm that calls itself a CPA practice should show up on the Mississippi State Board of Public Accountancy lookup. The Mississippi business entity search shows whether the firm's legal entity exists and its status. A sole proprietor may not appear, which isn't a warning sign on its own. Mississippi publishes these records as open data, so our lists already carry the checks: we matched a registration for 21 of the 34 Mississippi firms we list. The Mississippi CPA register isn't one we can search automatically, so a CPA license on these pages reads Not verified until someone checks the board by hand.
