What kind of license do I need to open my business?

If you sell tangible personal property or perform a service taxable for sales tax, you will need a sales tax permit. To apply for a sales tax permit and open a new tax account, you can register on TAP.

The law requires a business to obtain, in addition to a sales tax permit, a permit for the privilege of engaging in the following activities:

  • Sale of beer and/or light wine
  • Sale of tobacco products
  • Sale or manufacture of alcoholic beverages

You can apply for your beer and tobacco permits in TAP. Find more information concerning application for an ABC permit.

If you are in business as a petroleum products distributor, use natural gas or compressed gas in engines or compressors, or operate railroad locomotives, you need to register for a Petroleum Tax Permit. Please contact the Petroleum Bureau at (601) 923-7150 for more information.

If you operate trucks or buses with a gross weight exceeding 26,000 lbs., three or more axles or a truck trailer combination with a gross weight exceeding 26,000 lbs., and Mississippi is your base state you may need an International Fuel Tax Agreement (IFTA​) License and decal. Contact the Petroleum Bureau at (601) 923-7150 for more information.

If you are a Mississippi resident and you operate trucks or buses in interstate commerce with a gross weight exceeding 26,000 lbs., three or more axles or a truck trailer combination with a gross weight exceeding 26,000 lbs., you may need an apportioned International Registration Plan (IRP) license​ plate and cab card. Contact the Motor Vehicle Licensing Bureau at (601) 923-7100 for more information.

Any entity that conducts business within the state of Mississippi may be required to register for one or more tax specific identification numbers, permits, and/or licenses. In Mississippi there is not a central licensing authority for the various regulatory and professional licenses which may be required for businesses, so it is advisable to contact all agencies that you feel may affect your business.

How do I register to get a tax account?

You should file your returns even if you have no income to report, no business activity to report, or you owe no tax. Your failure to timely file a tax return may result in an estimated assessment of your tax liability as well as assessment of penalties and interest. ​

Can I file my tax return and pay the tax online?

Yes, free online filing for sales, use, special county and city and withholding and tax is available at FileMS . Income tax returns may also be filed electronically using a tax preparer or online by using an approved service provider. Check E-filing Services​ for more information.

Back to top

Am I considered on-time if my return is postmarked by the due date?

Yes, a return is considered to have been filed with and received by the Department of Revenue on the date shown by the post office cancellation mark stamped on the envelope.

However, accelerated payments are required to be filed each June by taxpayers whose total average sales, use and/or withholding tax liabilities exceed $50,000 per month for the preceding calendar year. Accelerated payments must be received by the Department of Revenue no later than June 25 in order to be considered timely made.​

If I close my business should I notify the Department of Revenue?

It is your responsibility to notify the Department of Revenue of any changes related to your business including changes in your address, changes in corporate officers, or changes in ownership. It is also important to file a final return when a business closes or is sold.​

Back to top

Will my records be kept confidential?

Mississippi law specifically states that all tax, financial and application information received by the Department of Revenue is confidential and will only be used for official purposes. Any current or former employee who discloses confidential tax information is subject to criminal penalties.​

Back to top

What is the statute of limitations?

The statute of limitations defines the time period during which a refund claim may be filed, an assessment may be initiated, or a collection activity may occur. Depending upon tax type, the statute of limitations begins running when a tax return is filed, or on the due date of the return. The statute of limitations is typically 36 months from that date as specified in the various tax laws.

If a tax return is filed prior to the due date of the return, then the return is considered to have been filed on the due date for purposes of the statute of limitations. If a return is not filed, the statute of limitations does not begin running until an assessment is made for that tax period. The statute of limitations can also be extended beyond the normal time frame if a false or fraudulent return is filed with intent to evade tax.​

Can I file by fax?

No, we do not accept tax returns by fax.​

Back to top

May I get an extension of time to fill out the return?

For Income tax, a six-month extension of time to file the return may be granted. The extension of time does not extend the time to pay the tax, but only extends the time to file a return. Tax paid after the due date is subject to interest and penalty charges. The Department of Revenue accepts a copy of the federal extension filed with the return to grant the extension.

For all other tax types, the Department of Revenue does not extend the time to file an overdue tax return. The Commissioner is authorized to provide an extension of time to file the return for good cause, as example when a natural disaster creates a hardship for filing the return on time. In these cases, the tax remains due and interest may apply for late payment.​

Back to top

Should I notify the Department of Revenue if the business has a change to its name, address, or ownership or if the business ceases operating in Mississippi?

Yes, you must notify the Department of Revenue when your business has any change to its name, address, or ownership or when you cease operating in Mississippi. You can notify the Department of Revenue by marking the “final return” box on your return, by letter, or you may attach a note to your monthly return.

If your name or ownership changes and you receive a different Federal Employer Identification Number (FEIN), you must file a new application with the Department of Revenue and update your information. If you cease operations, you must be sure to file a return for the last month of operations even if you were in business only a few days during that month. ​

What records should I keep for Mississippi tax purposes, and how long should I keep them?

You must keep a complete copy of your tax returns and all records pertaining to your business for a minimum of 4 years so the Department of Revenue can determine how you computed your tax liabilities. The required records include, but are not limited to, all purchases, receipts, inventories, sales (whether taxable or exempt), distribution, and consumption of products. Your records must be kept in a place and manner easily accessible for review by Department of Revenue representatives. ​
