Nonresident shareholder withholding. If a nonresident individual shareholder has not signed and returned Form 12N, the S corporation itself must remit Nebraska tax on that shareholder's ENTIRE distributive share of Nebraska S corporation taxable income — not on cash actually distributed — at 5.20% for 2025 and 4.55% for 2026. The classic fact pattern: an owner incorporates in Nebraska, later moves out of state, keeps the S corp, and never collects a Form 12N from themselves; the assessment lands on the corporation. Because the amount is computed on allocated income rather than distributions, an S corp that distributed nothing can still owe a large withholding balance. Second, now-permanent trap: the retroactive 2018-2022 PTET election window closed December 30, 2025 and cannot be reopened, so any owner who was told to "go back and elect PTET for prior years" has missed it.
S-corp election in Nebraska
In short
No Nebraska corporate income tax or franchise tax on an ordinary S corp, but mandatory nonresident-shareholder withholding (4.55% for 2026) is an entity-level obligation, plus a biennial occupation tax report to the Secretary of State.
Does Nebraska recognize the federal S election?
Nebraska automatically recognizes the federal S election; there is no separate Nebraska S election. Per the 2025 Nebraska S Corporation booklet: "The Nebraska S Corporation Income Tax Return, Form 1120-SN, must be filed by every S corporation, as defined by Internal Revenue Code (IRC) 1361, with income from Nebraska sources." Form 1120-SN must also be filed by any S corp distributing Nebraska incentive credits to shareholders. QSSSs follow federal: "Any subsidiary of an S corporation that is treated as a Qualified Subchapter S Subsidiary (QSSS) for federal income tax purposes will be treated in the same manner for Nebraska income tax purposes." S-corp financial institutions must file BOTH Form 1120NF and Form 1120-SN. Do not confuse Nebraska's optional PTET election with a state S election — they are unrelated.
Tax the entity still owes
Nebraska imposes no corporate franchise or net worth tax on an ordinary S corporation; the recurring state-level charge is the biennial occupation tax report filed with the Secretary of State. Do NOT accept the widely-repeated secondary-source claim that "Nebraska imposes a corporate-level tax of 5.84% on S corporation net income" — 5.84% was the Nebraska C-corporation rate and does not apply to a pass-through S corp. The real entity-level cash obligation is nonresident withholding: an S corp that did not make the PTET election "must remit Nebraska income tax withholding for each nonresident individual shareholder who does not complete a Nebraska Nonresident Income Tax Agreement, Form 12N," computed on the shareholder's share of Nebraska S corporation taxable income — 5.20% for 2025, and 4.55% for 2026 as Nebraska's top individual rate steps down under LB 754 (2.46% / 3.51% / 4.55% brackets for 2026, falling to 3.99% in 2027). Estimated income tax payments are required from S corporations for tax years beginning on and after January 1, 2024.
Registering for payroll
(1) Withholding: register with the Nebraska Department of Revenue using Form 20, Nebraska Tax Application (online via NebFile/DOR's registration system, or mailed/faxed if adding an account to an existing registration); file Form 941N withholding returns and Form W-3N annual reconciliation with W-2s. (2) Unemployment insurance/SUTA: register online with the Nebraska Department of Labor (dol.nebraska.gov) UI Tax system for a UI account number and file quarterly combined tax reports. Separately note that nonresident SHAREHOLDER withholding is not payroll withholding — it is reported on Nebraska Schedule III with the 1120-SN and is a distinct obligation.
Annual filings
Form 1120-SN — "This return must be filed on or before the 15th day of the third month following the close of the taxable year," i.e. March 15 for calendar-year filers, matching the federal 1120-S (unlike Kansas, Missouri, Iowa and Oklahoma, which all push later). Extension: attach a copy of a timely-filed federal Form 7004, or file Form 7004N by the original due date if a Nebraska tentative payment is needed or no federal extension is requested; total extension cannot exceed seven months past the original due date, and an extension of time to file does not extend time to pay. Nebraska Schedules A, I, II, III, K-1N and Schedule PTET as applicable; Schedule K-1N to each shareholder. Form 12N collected from each nonresident individual shareholder (or withhold instead). Form 2220N to compute estimated tax underpayment penalty. Secretary of State biennial occupation tax report: domestic and foreign business corporations and professional corporations file in EVEN-numbered years, "due in the even numbered years by March 1, delinquent April 15"; LLCs file in ODD-numbered years, "due in the odd numbered years by April 1, delinquent June 16." Failure to file by the delinquency date leads to administrative dissolution or revocation. Payroll: Form 941N and W-3N, plus NDOL quarterly UI reports.
Pass-through entity tax
Yes. Nebraska PTET, enacted by LB 754 (2023). For tax years AFTER 2022 the election is made on Form PTET-E (Pass-Through Entity Tax Election for Tax Years After 2022) submitted through the Department's secure file sharing system, or simply by checking Box 5 on Form 1120-SN. Deadline: "on or before the due date of the partnership's or S corporation's Nebraska return, including any approved extension." It is annual — "A pass-through entity is required to make a separate election for each tax year" — and "Once the election is made for a tax year the election is irrevocable and binding." RATES: 5.20% for 2025 and 4.55% for 2026, tracking the top individual rate. Estimated payments: "For tax years after 2023, a pass-through entity is required to make estimated payments when its PTET liability after credits is $400 or more." Report on Nebraska Schedule PTET, which also allocates the refundable PTET credit to shareholders. RETROACTIVE WINDOW IS CLOSED: elections for tax years 2018 through 2022 were made on Form PTET-ER and had to be filed "on or before December 30, 2025" — that opportunity is permanently gone as of today. No SALT-cap sunset in the Nebraska statute.
