Mississippi Form 89-350: Withholding Certificate Online

What is Form 89-350?

Form 89-350, the Mississippi Employee's Withholding Exemption Certificate, is how you claim your personal exemption for Mississippi income tax withholding. Your employer uses the total exemption you claim on line 6 with the state withholding tables. The federal Form W-4 doesn't set Mississippi withholding, so Mississippi employees complete this certificate as well.

Mississippi counts exemptions in dollars. The current edition (Rev. 10/25) sets $6,000 for a single person, $12,000 for a married couple (which working spouses split between them in multiples of $500), $9,500 for a head of family, and $1,500 for each dependent and for each box ticked for age 65 or blindness. Line 7 lets you ask for extra withholding, and line 8 is for military spouses who are exempt.

With VergeHR you fill out the 89-350 online in a guided form. VergeHR pre-fills your name from the employee records in Files, enters the amount the form sets for your status, adds up line 6, checks that a working spouse's share is in $500 steps, and prints your answers into the Department of Revenue's own fillable PDF. The finished form is saved in Files and can be sent for e-signature. VergeHR never submits it anywhere — you give the certificate to your employer yourself.

The 2025 edition has 1 page. VergeHR asks for it in 3 parts, and it is signed by Employee:

Lines 7–8: Extra withholding or military spouse exemptionEmployee

How to fill out Form 89-350, step by step

1 Name, SSN and residence

Enter your name, Social Security number, and your residence: number and street, city or town, state and ZIP code.

2 Lines 1–3 — Your personal exemption

Check one status. Single people claim $6,000 on line 1. Married people with a spouse who isn't employed claim $12,000 on line 2(a). If your spouse is employed, the $12,000 may be split between you in any way you choose in multiples of $500 — for example $6,500 and $5,500 — and you enter your share on line 2(b). A head of family, a single person who keeps a home that is the main home of themselves and at least one dependent, claims $9,500 on line 3.

VergeHR enters the fixed amounts for you and checks that a line 2(b) share is a multiple of $500 and no more than $12,000.

3 Line 4 — Dependents

You may claim $1,500 for each dependent, other than yourself and your spouse, who gets their chief support from you and qualifies as a dependent for federal income tax. A head of family leaves out the dependent that qualifies them as head of family. Married couples may divide their dependents between them however they choose. Enter the number claimed; VergeHR multiplies it by $1,500.

4 Line 5 — Age and blindness

Tick a box for each person — husband, wife, or single — who is 65 or older before the end of the tax year, and each who is blind. Each box is worth $1,500. There is no extra exemption for a dependent's age or blindness.

5 Lines 6–7 — Total and extra withholding

Line 6 is the total of lines 1 through 5, which VergeHR adds up. On line 7 you can enter an extra dollar amount to withhold each pay period, if your employer agrees.

6 Line 8 — Military spouses

If you meet the conditions of the Servicemembers Civil Relief Act as amended by the Military Spouses Residency Relief Act and have no Mississippi tax liability, write Exempt on line 8. You must attach a copy of federal Form DD-2058 and a copy of your military spouse ID card so your employer can validate the claim.

7 Sign and date

You declare, under the penalties for filing false reports, that the exemption you claim doesn't exceed what you are entitled to, or that you are entitled to exempt status. Sign and date the certificate and hand it to your employer.

Common Mistakes to Avoid

Both spouses claiming the full $12,000 when both work — together you may not claim more than $12,000.
Splitting the married exemption in amounts that aren't multiples of $500.
A head of family counting the dependent that makes them head of family again on line 4.
Claiming the age or blindness exemption for a dependent — it is only for you and your spouse.
Forgetting to file a new certificate within 30 days after your exemption status changes.
Claiming line 8 without attaching the DD-2058 and the military spouse ID copy.

After You Fill It Out

Sign and date the certificate and give it to your employer, who keeps it with their records. VergeHR saves a copy in the person's folder in Files, and you can send the PDF for e-signature if your employer accepts that.

If you don't file a certificate, the form says your employer must withhold Mississippi income tax from your total wages without the benefit of any exemption.

If your employer believes you have claimed an excess exemption, the form asks them to advise the Department of Revenue.
