S-Corporation Election Package (Form 2553 + Idaho S-Election)

S-CORPORATION ELECTION PACKAGE — IDAHO

OVERVIEW

This package guides an Idaho corporation (or an Idaho LLC electing corporate treatment) through electing federal S-corporation status on IRS Form 2553 and satisfying the Idaho state overlay. An S election causes income, losses, deductions, and credits to pass through to shareholders, avoiding entity-level federal income tax under Subchapter S (26 U.S.C. §§ 1361–1379).

Idaho in one line: Idaho conforms to the federal S election — there is no separate Idaho S election. A corporation filing as an S corporation for federal purposes files Form 41S, and for nonresident shareholders the entity uses pass-through withholding, a composite return (Idaho Code § 63-3022L), or the elective affected business entity (ABE/PTE) tax (Idaho Code § 63-3026B).

PART 1 — FEDERAL ELIGIBILITY CHECKLIST (IRC § 1361)

An entity may elect S status only if every requirement below is satisfied on the effective date and continuously thereafter. A single violation terminates the election (26 U.S.C. § 1362(d)(2)).

Entity Requirements — 26 U.S.C. § 1361(b)(1)

☐ The entity is a domestic corporation or a domestic eligible entity (LLC) that will be treated as a corporation
☐ The entity has no more than 100 shareholders (family members may be counted as one — § 1361(c)(1))
☐ The entity has only one class of stock (differences in voting rights alone are permitted — § 1361(c)(4))
☐ The entity is not an ineligible corporation (no financial institution using the § 585 reserve method; no insurance company under Subchapter L; no § 936 possessions-credit corporation; no current/former DISC)

Shareholder Requirements — 26 U.S.C. § 1361(b)(1)(B)–(C)

☐ All shareholders are eligible: individuals, estates, certain trusts, or qualifying tax-exempt organizations
☐ No shareholder is a partnership, a corporation, or a nonresident alien (§ 1361(b)(1)(B)–(C))
☐ Any trust shareholder is a permitted type only: grantor trust, testamentary trust (2-year limit), voting trust, QSST, or ESBT (§ 1361(c)(2), (d), (e))
☐ Each shareholder's consent is documented (all shareholders must consent — § 1362(a)(2))

PART 2 — IRS FORM 2553 LINE-BY-LINE GUIDE

Timing — 26 U.S.C. § 1362(b)

☐ Standard deadline: file no later than 2 months and 15 days after the beginning of the tax year the election is to take effect (i.e., by the 15th day of the 3rd month)
☐ Alternative: file at any time during the tax year preceding the year the election is to take effect
☐ New entity: the 2-month-and-15-day clock starts on the earliest of (a) first issuance of stock, (b) first having assets, or (c) first doing business

Part I — Election Information

Part II — Fiscal Tax Year (if a non-calendar year is requested)

☐ Complete Part II only if Box F selects a fiscal year — state the business-purpose or § 444 basis
☐ Most S corporations adopt a calendar year; a § 444 election may require a required payment (Form 8752)

Late Election Relief — Rev. Proc. 2013-30

If the deadline has passed, relief may be available when filed within 3 years and 75 days of the intended effective date:

☐ Write "FILED PURSUANT TO REV. PROC. 2013-30" across the top of Form 2553
☐ The entity intended to be an S corporation as of the intended effective date
☐ Failure to qualify was solely because Form 2553 was not timely filed
☐ Reasonable cause statement attached, signed under penalties of perjury
☐ All required returns are consistent with S status (or none were due)
☐ All shareholders from the effective date forward report consistently with S status

PART 3 — SHAREHOLDER CONSENT STATEMENT

Under 26 U.S.C. § 1362(a)(2), all shareholders on the day of the election must consent. The consent is incorporated in column K of Form 2553; the table below documents it.

Consent language: Each shareholder, by signing above, consents to the corporation's election under 26 U.S.C. § 1362(a) to be treated as an S corporation and represents that the information stated is true and correct.

Community property note: in a community-property context, the consenting spouse who has a community interest in the stock must also consent (Treas. Reg. § 1.1362-6(b)(2)). Idaho is a community-property state — where stock is community property, both spouses are treated as shareholders and both must consent.

PART 4 — ENTITY INTERPLAY (LLC / FORM 8832)

☐ Corporation electing S status: a domestic corporation files only Form 2553 — no Form 8832 is required
☐ LLC electing S status: an LLC that has not elected corporate treatment may file Form 2553 alone; a timely, valid Form 2553 is treated as a deemed entity-classification election (Form 8832) to be taxed as a corporation, effective the same date (Treas. Reg. § 301.7701-3(c)(1)(v)(C))
☐ LLC already taxed as a C corporation (prior Form 8832): file Form 2553 only
☐ Confirm the Idaho LLC is in good standing with the Idaho Secretary of State before filing
☐ Confirm the entity's governing documents (operating agreement / bylaws) do not create a prohibited second class of stock (e.g., disproportionate distribution/liquidation rights)

PART 5 — IDAHO STATE OVERLAY (KEY SECTION)

S-Corp Recognition

☐ Idaho conforms to the federal S election — there is NO separate Idaho S election. A corporation filing as an S corporation for federal income tax purposes must file Form 41S if it is transacting business in Idaho.
☐ Retain the IRS acceptance letter (CP261); a copy may be required with the first Idaho return.

Return Form

☐ File Idaho Form 41S — S Corporation Income Tax Return annually (and provide each shareholder an Idaho Form ID K-1)
☐ File on or before the 15th day of the 4th month following the close of the tax year (calendar-year due date is April 15)

Nonresident Shareholders — Three Options

For each nonresident shareholder's Idaho-source pro-rata share, the S corporation must use one of:

☐ Pass-through withholding under Idaho Code § 63-3036B — the entity withholds and remits Idaho tax on the nonresident's distributive share; or
☐ Composite return under Idaho Code § 63-3022L — the entity reports and pays Idaho tax for participating nonresident owners at the corporate rate, in lieu of § 63-3036B withholding; or
☐ The nonresident files an Idaho individual return directly (with an agreement, where required)

Optional — Affected Business Entity (ABE) / Pass-Through Entity Tax — Idaho Code § 63-3026B

☐ A partnership or S corporation may make an annual election (a separate election each taxable year) to become an "affected business entity" (ABE) taxed at the entity level — Idaho's SALT-cap workaround
☐ The election is made on Form ABE (Affected Business Entity), filed with a timely original Form 41S (or by an amended return filed before the original due date — the 15th day of the 4th month)
☐ The election must be signed by each member at the time of filing, or by an authorized officer/manager/member representing authorization under penalty of perjury
☐ ABE income is taxed at the corporate rate under Idaho Code § 63-3025 (the elective tax is described in Idaho Code § 63-3082); the ABE must pay the tax for each member that is not an Idaho resident
☐ Each member receives a credit for the entity-level tax against their Idaho tax

Idaho Entity-Level Tax — Summary

PART 6 — POST-ELECTION COMPLIANCE

IRS Confirmation

☐ Expect IRS acceptance notice CP261 (or denial) within ~60 days; if none, call IRS Business & Specialty Tax Line (800) 829-4933
☐ Retain the CP261 permanently with corporate records

Reasonable Compensation

☐ Pay shareholder-employees reasonable compensation as W-2 wages before non-wage distributions (IRS scrutinizes under-compensation that recharacterizes wages as distributions to avoid FICA)
☐ Document the basis for compensation (duties, time, comparable salaries)

Built-In Gains Tax — 26 U.S.C. § 1374

☐ If the corporation converted from C to S, a corporate-level built-in gains (BIG) tax applies to net recognized built-in gain on appreciated assets disposed of during the 5-year recognition period; track each asset's basis and fair market value as of the conversion date

Excess Net Passive Income Tax — 26 U.S.C. § 1375

☐ If the corporation has accumulated C-corporation E&P and passive investment income exceeds 25% of gross receipts, a corporate-level tax applies; if this persists for 3 consecutive years, the S election terminates under § 1362(d)(3)

Ongoing Filings

☐ File federal Form 1120-S and issue Schedule K-1 to each shareholder annually
☐ File Idaho Form 41S and Idaho Form ID K-1 annually; maintain PTE-withholding, composite, or ABE (Form ABE) documentation for nonresidents
☐ Maintain a single class of stock and continuous shareholder eligibility

PART 7 — REVOCATION (26 U.S.C. § 1362(d)(1))

☐ Voluntary revocation requires consent of shareholders holding more than 50% of the issued and outstanding shares (voting and nonvoting) on the date of revocation
☐ File a revocation statement with the IRS service center where Form 2553 was filed (no official form; use a statement that the corporation revokes its § 1362(a) election, listing the EIN, number of shares outstanding, and the intended effective date)
☐ Attach a statement of consent signed by the consenting shareholders
☐ Effective date: if filed on or before the 15th day of the 3rd month of the tax year, effective the first day of that year; otherwise effective the first day of the following tax year (a prospective date may also be specified)
☐ After revocation/termination, a 5-year waiting period applies before re-electing without IRS consent (§ 1362(g))
☐ Idaho status follows the federal treatment; notify the Idaho State Tax Commission and resume filing the Idaho C-corporation return (Form 41) as applicable
