Mississippi claim deadlines for employers

In Mississippi a request for separation information has to be answered within 10 calendar days from the date the notice was mailed. That is the window Unemploy exists to hold: the state decides the claim on whatever it has when it shuts.

The benefit-charge protest window is 14 calendar days from the date the notice was mailed. That one runs on the quarterly statement; the audit that reads it is free.

Every number on this page is the one in our rules table for Mississippi, with the page or statute it was read out of printed beside it. Nothing here is an average across states. If you think a line is wrong, the source is one click away. Tell us and we will fix the row.

The outline is the range across the 49 states the table has sourced. The solid bar is Mississippi.

The table carries no fact-finding window and no wage audit window for Mississippi. That is a gap in our table, not a statement that Mississippi holds none.

How the window is held

A deadline anybody has to remember is a deadline somebody misses. The Mississippi numbers above are not a reference table this site publishes and then forgets: they are the table Unemploy’s AI agents compute from.

An agent computes the due date, never assumes it

An agent puts each notice on the Mississippi row above and computes the date from it. Six different things can stop that computation, and each one refuses by name rather than falling back on a default number of days. A guessed deadline renders identically to a real one and puts a countdown on the screen, and the customer finds out it was wrong when the window has already shut.

An agent walks every open window, every thirty minutes

It escalates to you at three days left, at one day left and at two hours left. Inside the last window nothing quiets it, and it clears when the item is filed and not before.

You are the only person in it

An agent classifies the notice and sets the clock. An agent sends the questions to the manager who did the firing. An agent drafts the response from the answers, with the evidence under every sentence. You read it and press send. Nothing else waits on anyone, on either side.

Where each number comes from

One block per window: the number, the state’s own sentence, and anything about the row that is stranger than the number alone suggests.

Separation response

10 calendar days from the date the notice was mailed.

“The employer has, within ten (10) days from the mailing date or date of electronic delivery of Notice to Employer of Claim Filed and Request for Information (Form UI-21A) to submit to the Agency a written statement showing the date and detailed reason for the separation or the date and details with respect to the refusal of an offer of suitable employment from such employer, whichever is applicable, identifying the individual involved by name and Social Security account number.”Regulations of the Mississippi Department of Employment Security, Reg. 321.00 (CMSR 20-101-101)

Note from the rules table

MDES Reg. 321.00(B)(1). The next sentence states the consequence: 'Failure to furnish such information within the time required will result in the employer being denied eligibility for the relief of charges as provided in the referenced section of the Law.' A parallel 10-day rule at 321.00(B)(2) covers refusal of suitable work counted from the date of refusal, not from a notice: 'The employer has ten (10) days from the date of the refusal of an offer of suitable employment to notify the Agency in writing of such refusal, giving the date and details with respect thereto.' The form is UI-21A. Quote is from a PDF of the regulations published by MDES itself.

Charge protest

14 calendar days from the date the notice was mailed.

“This determination will be final unless the employer files an appeal within fourteen (14) days from the regular mailing or electronic mailing date or notification of the decision.”Regulations of the Mississippi Department of Employment Security, Reg. 321.00 (CMSR 20-101-101)

Note from the rules table

MDES Reg. 321.00(C). Mississippi issues a separate chargeability decision once the employer has timely furnished separation/refusal information, and that decision is appealable in 14 days. The same paragraph sets the next two steps: a further 14 days to appeal to the Board of Review, and 'Any decision of the Board of Review will become final ten (10) days after the date of mailing or notification of that decision.' Note the gate: an employer that missed the 10-day UI-21A window never gets a chargeability decision to protest.

Appeal of a determination

14 calendar days from the date the notice was mailed.

“an interested party must file an appeal for an initial or amended determination within fourteen (14) days of the date the determination was mailed to the last known address or delivered electronically to the email address on record.”Regulations of the Mississippi Department of Employment Security, Reg. 200.01 (CMSR 20-101-101)

Note from the rules table

MDES Reg. 200.01(A), citing Sections 71-5-517 and 71-5-519 of the Law. The regulation carries a weekend/holiday rollover: 'If the last day to appeal falls on a Saturday, Sunday, or other legal holiday, or day in which the Agency is closed for business, then the time allowed to appeal shall run until the end of the next business day.' The quote is the clause carrying the number; it begins mid-sentence after the 'Pursuant to Sections 71-5-517 and 71-5-519 of the Law,' preamble.

Relief grounds, in Mississippi’s own language

The table carries 2 sourced grounds for Mississippi. One of them is granted by the state on its own once the determination is final. We do not file for those and we do not bill for them.

Non-charging of benefits (eligibility conditioned on timely separation/refusal notice)

Benefits are non-charged as set out in Miss. Code Ann. § 71-5-355(2)(b)(ii), but ONLY where the employer furnished notice of the separation or refusal of suitable work in the manner and within the time required (Form UI-21A within 10 days, or refusal notice within 10 days of the refusal).

Filed on Form UI-21A. MDES Reg. 321.00(A)-(B); Miss. Code Ann. § 71-5-355(2)(b)(ii).

“An employer shall be eligible for non-charging as provided in (A) above only when they have furnished the Agency with notice regarding the separation from work or refusal to accept an offer of suitable work, whichever is applicable, in the manner and within the time required, by one of the following methods:”Regulations of the Mississippi Department of Employment Security, Reg. 321.00 (CMSR 20-101-101)

Mississippi's regulations do not enumerate the substantive non-charging grounds; they point to Miss. Code Ann. § 71-5-355(2)(b)(ii) for the list. I did not fetch § 71-5-355 this session, so the substantive grounds are NOT sourced here -- see 'missing'. What IS sourced, and is the operative procedural rule, is that timely UI-21A filing is a precondition to any non-charging at all.

Failure to furnish separation information is an admissionAutomatic

The employer fails to furnish requested separation information within the specified time.

Granted by the state on its own once the determination is final. There is nothing to file and nothing we bill for.

“It will be presumed that employers who fail to furnish such information within the time required have admitted that the individual claiming benefits is not subject to disqualification.”Regulations of the Mississippi Department of Employment Security, Reg. 316.00 (CMSR 20-101-101)

This is the inverse of a relief ground -- an adverse automatic presumption -- but it is included because it is the rule that governs what happens when the separationResponse window is blown, and a deterministic table needs it. automatic: true because it applies without any agency finding.

Representation at a hearing

A non-attorney may represent an employer at a hearing in Mississippi

Mississippi permits a non-attorney to appear for an employer, and the authority for that is on the jurisdiction's own page. Unemploy can appear at a hearing in Mississippi.

MDES Reg. 204.00(A), 'Representation before Administrative Law Judges and Board of Review'. Directly on point for a corporate employer: an officer OR a duly authorized representative, neither required to be an attorney. Full paragraph also covers individuals and partnerships. The fee provisions in 204.00(B)-(C) cap fees charged to CLAIMANTS only and do not restrict who may appear for an employer.

Notes on the Mississippi row

What the person who sourced this row wanted the next reader to know, verbatim.

Mississippi's appeal window is unusually short at 14 days, and the chargeability protest is also 14 days -- so a deterministic table must not carry a 30-day default into MS.

Mississippi gates charge relief on the separation response: miss the 10-day UI-21A window and the employer is 'denied eligibility for the relief of charges' outright, and is additionally presumed under Reg. 316.00 to have admitted the claimant is not disqualified.
