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.​

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. It only extends the time to file a return. Tax paid after the due date is subject to interest and penalty charges.

The Commissioner is also authorized to provide an extension of time to file the return for good cause, for example, when a natural disaster creates a hardship for filing the return on time. In these cases, the Department will issue a notice on the extended filing and/or payment due dates.
