What a marketing agency business needs to open
Done-for-you marketing — ads, social, SEO, or content — for local or niche businesses. The setup areas that usually matter: Business registration + contracts with clear scope, E&O / professional liability, Master service agreements and SOWs, Retainer + performance pricing, Reporting cadence. Typical cost to get operational: $500–$5,000.
Pick a structure (sole proprietor or LLC)
Most Mississippi owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $50, and formation typically takes immediate online. Confirm the current fee on the state site before you pay.
Name a registered agent
If you form an LLC or corporation, Mississippi needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
Register for Mississippi taxes
Mississippi has a state sales/use tax and has a state income tax. Mississippi LLC formation and the annual report are both filed free-of-charge online (report still mandatory).
Confirm local licenses and permits
Mississippi rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.
Open a business bank account and get insurance
Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.
Put the ongoing report on your calendar
Mississippi requires a annual report (about $0). free for LLCs, due April 15
