Delaware claim deadlines for employers

In Delaware a request for separation information has to be answered within 15 calendar days from the date printed on the notice. 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 15 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 Delaware, 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 Delaware.

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

How the window is held

A deadline anybody has to remember is a deadline somebody misses. The Delaware 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 Delaware 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

15 calendar days from the date printed on the notice.

“The last and base period employer(s) or agent(s) of the last and base period employer(s) shall return such notices completed, indicating the reason for the claimant’s separation from work with them and the individual claimant’s last date of work with them, within 15 days of the date contained on the separation notice.”19 Del. C. § 3317(b) - Filing of claim for benefit; regulations of Department; posting (Delaware Code Online, official)

Note from the rules table

Counts from THE DATE PRINTED ON THE SEPARATION NOTICE, not a mail date. The statute does not say 'calendar'; treated as calendar days. HARSH CONSEQUENCES: an employer or agent that fails to return the notice timely, fails to complete it, or 'responds inadequately' (defined in the statute as giving insufficient information to determine eligibility) is BARRED from later arguing disqualification under § 3314 AND barred from seeking relief from benefit wage charges / benefit charges under §§ 3349-3356, absent a good-cause release. The Department is then not required to issue any determination at all. Separately, § 3317(c): if the employer returns a timely notice that does NOT contest entitlement (or says lack of work), the employer is charged and gets no further appeal or charge relief on that claim. Applies to LAST and BASE PERIOD employers alike. Forms are BW-119/UC-119C.

Charge protest

15 calendar days from the date the notice was mailed.

“Such benefit charge notices shall become conclusive and binding upon the base period employer unless, within 15 days after the mailing of the notice thereof to the last known address or in the absence of mailing within 15 days after the delivery of such notice, a base period employer who is subject to assessments under § 3345(a) of this title files an application for review seeking relief from benefit wages or benefit charges charged to its experience merit rating account.”19 Del. C. § 3355(b) - Notice to employers of benefits paid and status of accounts; employer applications for review and redetermination... (relief from charges)

Note from the rules table

Notices are QUARTERLY (§ 3355(a)). Only employers subject to assessments under § 3345(a) may apply - reimbursing employers are outside this route. Grounds are strictly limited to the two in § 3355(b)(1)-(2) (see reliefGrounds). After the Department's representative decides, a further 15 days runs to file an application for REDETERMINATION (§ 3355(c)), then the appeals tribunal decision is final unless a Superior Court petition is filed within 15 days of delivery (§ 3355(d)). Delaware is mid-transition: 'benefit wages' apply before January 1, 2027 and 'benefit charges' from January 1, 2027 onward.

Appeal of a determination

15 calendar days from the date the notice was mailed.

“Unless a claimant or a last employer who has submitted a timely and completed separation notice in accordance with § 3317 of this title files an appeal within 15 calendar days after such Claims Deputy’s determination was mailed to the claimant’s and last employer’s last known addresses or otherwise delivered by the Department to the claimant and the last employer, the Claims Deputy’s determination shall be final and benefits shall be paid or denied in accordance therewith.”19 Del. C. § 3318(b) - Decision on claim by deputy; notice; appeal (Delaware Code Online, official)

Note from the rules table

STANDING PRECONDITION, not just a clock: only a last employer WHO SUBMITTED A TIMELY AND COMPLETED SEPARATION NOTICE under § 3317 may appeal at all. Miss the 15-day separation notice and the 15-day appeal window is irrelevant. Benefits awarded are paid during the appeal notwithstanding the appeal. The next level (appeals tribunal to the Unemployment Insurance Appeal Board) is also 15 days, per § 3318(c).

Relief grounds, in Delaware’s own language

The table carries 3 sourced grounds for Delaware.

Claimant's separation from the base period employer was separate from and prior to the qualifying separation

Base period employer files a timely (15-day) application for review of its benefit charge notice AND the claimant's separation from that base period employer was separate from and prior to the separation from the last employer, the base period employer is not also the last employer, and that separation was not qualifying under 19 Del. C. § 3314(1), (2) and (7).

Filed on a letter. 19 Del. C. § 3355(b)(1).

“The claimant’s separation from the base period employer (if such separation was separate from and prior to the claimant’s separation from the claimant’s last employer and if the base period employer is not also the last employer) was not qualifying under § 3314(1), (2) and (7) of this title”19 Del. C. § 3355(b)(1)

One of only TWO permitted grounds - § 3355(b) says relief is available 'only on the basis that' (1) or (2). Barred outright if the employer failed to return a completed separation notice timely under § 3317, absent a good-cause release. § 3355(b) also states: 'no employer shall have standing to seek benefit wage or benefit charges charge relief pursuant to the procedure established in §§ 3317 through 3325 of this title' - i.e. the § 3355 review is the exclusive route, not the benefit-appeal track.

Source: 19 Del. C. § 3355(b)(1) Read 2026-09-02.

Department made an administrative error calculating the benefit wages or charges

Base period employer files a timely (15-day) application for review and the Department administratively erred in calculating the amount of benefit wages or benefit charges charged to the account.

Filed on a letter. 19 Del. C. § 3355(b)(2).

“The Department administratively erred in calculating the correct amount of certain benefit wages or benefit charges charged to its account.”19 Del. C. § 3355(b)(2)

Same 15-day window and same § 3317 timeliness bar as ground (1).

Source: 19 Del. C. § 3355(b)(2) Read 2026-09-02.

Base period employer filed a timely and complete separation notice under § 3317

Base period employer submitted a timely and completed separation notice under § 3317. Where the last employer is ALSO a base period employer on the claim, charge relief is decided by the determination on the claimant's last separation rather than by a separate § 3355 application.

Filed on a letter. 19 Del. C. § 3318(a).

“Base period employers who have submitted timely and completed separation notices in accordance with § 3317 of this title may seek relief from benefit wage charges (prior to January 1, 2027) and benefit charges (January 1, 2027, and after) charged to their experience merit rating accounts in accordance with § 3355 of this title except that for a claim in which the last employer is also a base period employer for such claim, the issue of benefit wage charge relief (prior to January 1, 2027) or benefit charge relief (January 1, 2027, and after) or such base period employer shall be determined in accordance with the determination on the issue of the claimant’s last separation from such employer.”19 Del. C. § 3318(a)

ROUTING RULE, not a substantive ground: if the last employer is also a base period employer, do not expect a separate charge-relief adjudication - it rides on the separation determination and therefore on the § 3318(b) appeal, not on a § 3355 application. The sentence contains an apparent drafting artifact ('or such base period employer') reproduced verbatim from the official code.

Where it gets filed

The table carries no sourced filing channel for Delaware yet. We will not name a portal, an address or a fax number we cannot show you the source for.

Representation at a hearing

We have not sourced the representation rule for Delaware

Nobody has put an authority in this row for Delaware, so we do not know whether a non-attorney may appear for an employer here. Unsourced is not permission: Unemploy does not represent employers at hearings in Delaware, and will not until there is a link in this row. We prepare the packet and route it to an attorney.

JUDGED INSUFFICIENT. This says an attorney is optional; it does NOT say that a non-attorney may appear FOR a corporate employer, and it is a claimant-and-employer preparation tip rather than a rule of appearance. A human should read 19 Del. Admin. Code 1201, 'Unemployment Insurance Appeal Board Regulations' (regulations.delaware.gov/AdminCode/title19/1201) - that page renders its text via JavaScript and returned an empty body to both curl and WebFetch this session - and any Appeals Referee hearing rules published by the Delaware Division of Unemployment Insurance.

Notes on the Delaware row

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

Delaware is mid-transition between two charging systems: 'benefit wage charges' apply to periods prior to January 1, 2027 and 'benefit charges' from January 1, 2027 onward. Every relief and protest provision in §§ 3317, 3318 and 3355 is written in both registers. A deadline table built today should carry both labels.

Delaware's separation notice deadline is the single most consequential date in the state: missing it forfeits the disqualification argument, the charge relief, AND standing to appeal under § 3318(b).

Statute text was read from delcode.delaware.gov, the State of Delaware's official Delaware Code Online (Title 19, Chapter 33, subchapters II and III).

PRIMARY vs SECONDARY, SEPARATION RESPONSE - 7 vs 15 days. The Delaware Division of Unemployment Insurance's own UI Employer Handbook (https://laborfiles.delaware.gov/main/dui/handbook/UI%20Employer%20Handbook.pdf) says 7 days: "the information must be returned to the Division within 7 days of the date contained on the \"Separation Notice\"" and, on its highlights page, "You must provide the Division of Unemployment Insurance the reason a former employee is unemployed within 7 calendar days from the date on the separation notice the division will send to you when a claim for unemployment insurance benefits is filed." The CURRENT official Delaware Code at delcode.delaware.gov says 15 days: "...shall return such notices completed... within 15 days of the date contained on the separation notice." The statute governs; 19 Del. C. § 3317's history line shows a recent amendment (84 Del. Laws, c. 365), so the handbook appears to predate it. USE 15, and warn the user that the state's own handbook still says 7.

PRIMARY vs SECONDARY, APPEAL - 10 vs 15 calendar days. The same UI Employer Handbook says: "The appeal must be filed with the Division within 10 calendar days after the claims deputy’s determination was mailed to the last known addresses of the parties or it becomes final and unappealable." The current official Delaware Code § 3318(b) says 15 calendar days. Same cause - the handbook predates the amendment recorded in § 3318's history (84 Del. Laws, c. 365). USE 15. The handbook likewise says 10 days for the appeal to the Unemployment Insurance Appeal Board and 10 days to Superior Court, where § 3318(c) now says 15.
