USA State Payroll Rates + Resources: State of Mississippi: Filing State Income Taxes, W2s, and 1099s
The purpose of this documentation is to outline the processes and requirements associated with filing state income taxes as well as how to file W-2s and 1099s, if needed, in the state of Mississippi.
State Income Tax Withholding
To determine the amount of state income tax withholding, employees should complete a Mississippi Employee Withholding Exemption Certificate (89-350). Every employee, on or before the date of commencement of employment, shall furnish his or her employer with a signed Mississippi Employee Withholding Exemption Certificate (89-350) relating to personal exemptions, and/or an additional amount to be withheld each pay period.
Employers are required to keep copies of completed state Forms 89-350 for their employees in their files. The forms serve as verification that state income taxes are being withheld according to the employee’s instructions and needs to be available for inspection if the state requests it.
The Forms W-4 and MS 89-350 generally are valid until the employee provides new ones. However, employees who claim exemption from withholding must renew the exemption annually by filing new Forms W-4 or MS 89-350 by February 15th of each year.
State Income Tax Withholding Reporting and Deposits
Withholding Tax returns are filed monthly or quarterly depending on the average amount of tax you withhold each month. You will be notified of your filing status. Generally, every employer with average liability of $300 or more per month must file a monthly tax return. Employers with smaller tax liabilities may file quarterly returns.
|Filing Schedule||Average Monthly Liability||Due Date|
|Monthly||$300 +||The 15th of the following month.|
|Quarterly||< $300||The 15th of the following month after the close of the quarter.|
If a due date falls on a Saturday, Sunday, or legal holiday, the due date becomes the next business day.
Withholding Tax Returns are filed in TAP.
W-2 and 1099 Forms
W-2 and 1099 forms should be submitted with an Annual Information Return (Form 89-140). A separate Form 89-140 must be submitted for each type of return. The form is not filed with electronic returns.
Employers that issue 25 or more W-2s, 1099s or other information returns are required to electronically submit those in the required formats to the Department of Revenue (DOR) through the Taxpayer Access Point (TAP).
Other Due Dates:
|Forms||Due Date to DOR|
