S-Corporation Election Package (Form 2553 + State S-Election) — Iowa

S-CORPORATION ELECTION PACKAGE (FORM 2553 + STATE S-ELECTION) — IOWA

OVERVIEW

An S-corporation election lets a qualifying corporation (or an LLC that elects corporate treatment) pass income, losses, deductions, and credits through to its shareholders, avoiding entity-level federal income tax under Subchapter S (26 U.S.C. §§ 1361–1379). The election is made by filing IRS Form 2553 under 26 U.S.C. § 1362(a).

This package walks through:

• Part 1 — Federal eligibility checklist (IRC § 1361)
• Part 2 — Form 2553 line-by-line and timing rules
• Part 3 — Shareholder consent statement
• Part 4 — Entity interplay (LLCs, deemed corporate election)
• Part 5 — Iowa state S-corporation overlay
• Part 6 — Post-election compliance
• Part 7 — Revocation

Iowa in one line: Iowa automatically recognizes the federal S election — there is no separate Iowa S-election form. The S corporation files Form IA 1120S and, for any nonresident shareholders, must file the IA PTE-C composite return under Iowa Code § 422.16B (or make the elective entity-level tax under Iowa Code § 422.16C).

PART 1 — FEDERAL ELIGIBILITY CHECKLIST (26 U.S.C. § 1361)

Confirm every item below before filing. A single failed requirement makes the corporation an "ineligible corporation" and voids the election.

Entity-Level Requirements (§ 1361(b)(1))

☐ The entity is a domestic corporation (or an LLC/eligible entity electing to be taxed as a corporation — see Part 4)
☐ The entity has no more than 100 shareholders (§ 1361(b)(1)(A); family members may be treated as one shareholder under § 1361(c)(1))
☐ The entity has only one class of stock (§ 1361(b)(1)(D)); differences in voting rights alone are permitted
☐ The entity is not an ineligible corporation under § 1361(b)(2) (e.g., a bank using the reserve method of accounting, an insurance company taxed under subchapter L, a § 936 possessions-credit corporation, or a DISC)

Shareholder Eligibility (§ 1361(b)(1)(B)–(C))

☐ Every shareholder is an individual, estate, eligible trust, or exempt organization — no partnerships, no C corporations, no nonresident aliens (§ 1361(b)(1)(B)–(C))
☐ Each individual shareholder is a U.S. citizen or resident alien
☐ Each trust shareholder qualifies as a grantor trust, testamentary trust (2-year window), QSST, ESBT, or voting trust (§ 1361(c)(2), (d), (e))
☐ Each exempt-organization shareholder qualifies under § 401(a) or § 501(c)(3) (§ 1361(c)(6))

Documentation Prerequisites

☐ Articles of Incorporation/Organization filed with the Iowa Secretary of State; entity in good standing
☐ EIN obtained from the IRS
☐ Bylaws (or LLC operating agreement) in place; single class of stock/economic-rights structure confirmed
☐ Each shareholder's SSN/ITIN, share count, percentage, and acquisition date collected for the consent statement

PART 2 — IRS FORM 2553 LINE-BY-LINE

Part I — Election Information

Timing — When to File (26 U.S.C. § 1362(b))

☐ General rule: File no later than two months and 15 days after the beginning of the tax year the election is to take effect (i.e., the 15th day of the 3rd month). For a calendar-year entity electing for 2026, the deadline is March 16, 2026 (March 15 falls on a Sunday).
☐ Preceding-year rule: The election may be filed at any time during the tax year preceding the first effective tax year.
☐ New entities: The 2-month-and-15-day period runs from the earliest of (a) the date the entity first had shareholders, (b) the date it first had assets, or (c) the date it began doing business.

Late-Election Relief — Rev. Proc. 2013-30

If the deadline passed, relief is generally available under Rev. Proc. 2013-30:

☐ The entity intended to be an S corporation as of the intended effective date
☐ The only reason it is not an S corporation is the failure to file Form 2553 timely
☐ There is reasonable cause for the failure, and the entity acted diligently to correct it
☐ The request is filed within 3 years and 75 days of the intended effective date
☐ The entity and shareholders reported consistently with S status (or no returns are yet due)
☐ Write "FILED PURSUANT TO REV. PROC. 2013-30" across the top of Form 2553
☐ Attach a reasonable-cause statement; all shareholders sign the consent (see Part 3)

PART 3 — SHAREHOLDER CONSENT STATEMENT

26 U.S.C. § 1362(a)(2) requires the consent of ALL shareholders who hold (or held) stock during the relevant period. Each shareholder signs Column K of Form 2553, or this consent statement is attached.

CONSENT TO S-CORPORATION ELECTION. The undersigned, being all of the shareholders of [____________________________________] (EIN [____________]), consent under 26 U.S.C. § 1362(a)(2) to the corporation's election to be treated as an S corporation effective [__/__/____], and each represents that the information below is true and correct.

PART 4 — ENTITY INTERPLAY (LLC AND DEEMED CORPORATE ELECTION)

LLC Electing S Status

An LLC is by default a disregarded entity (single member) or a partnership (multi-member). To be an S corporation it must first be treated as a corporation for federal tax purposes.

☐ Form 2553 alone (the deemed-8832 shortcut): Under Treas. Reg. § 301.7701-3(c)(1)(v)(C), an eligible entity that timely files Form 2553 is deemed to have also elected to be classified as an association taxable as a corporation (Form 8832) as of the same effective date. A separate Form 8832 is not required when Form 2553 is filed timely.
☐ Late filing: If the S election is late, follow Rev. Proc. 2013-30, which also provides the corporate-classification (deemed-8832) relief.

Corporation Already Taxed as a C Corporation

☐ A C corporation converting to S status should assess built-in gains tax exposure (§ 1374) and the disposition of any accumulated earnings and profits (E&P) — see Part 6.

PART 5 — IOWA STATE S-CORPORATION OVERLAY

Does Iowa Recognize the Federal S Election?

Yes — automatically. Iowa conforms to federal Subchapter S treatment. A corporation that is an S corporation for federal purposes is treated as an S corporation for Iowa income tax purposes. There is NO separate Iowa S-election form — the federal Form 2553 (and the IRS acceptance, CP261) controls.

☐ Confirm the entity is registered with the Iowa Secretary of State and has an Iowa tax account through GovConnectIowa

Iowa Return — Form IA 1120S

☐ File Form IA 1120S, Iowa Income Tax Return of S Corporation, annually with the Iowa Department of Revenue
☐ Issue an Iowa Schedule K-1 (IA 1120S K-1) to each shareholder reporting the Iowa distributive share
☐ The IA 1120S is generally due by the last day of the 4th month after the close of the tax year (Iowa allows an automatic filing extension if at least 90% of the tax is paid)

Nonresident Shareholders — Mandatory Composite Return (Iowa Code § 422.16B)

☐ Iowa imposes a composite-return mandate: an S corporation with one or more nonresident shareholders must file an IA PTE-C Iowa Composite Return and remit Iowa income/franchise tax on behalf of those nonresident members (Iowa Code § 422.16B, for tax years beginning on or after Jan. 1, 2022)
☐ Each nonresident member receives a refundable composite tax credit for the composite tax paid on the member's behalf (Iowa Admin. Code r. 701-405.8)

Elective Entity-Level Tax (PTE Election) — Iowa Code § 422.16C

☐ Iowa allows a separate annual, irrevocable election under Iowa Code § 422.16C for an S corporation to be taxed at the entity level (SALT-cap workaround; HF 352 (2023), retroactive to tax years beginning on or after Jan. 1, 2022)
☐ The election applies only to tax years for which the federal § 164(b)(6) individual SALT deduction limitation is in effect
☐ The entity-level tax is imposed at the rate under Iowa Code § 422.5 on Iowa-allocated taxable income; shareholders receive a refundable credit for their share
☐ Important interplay: if the § 422.16C election is made, the entity is not required to file the IA PTE-C composite return under § 422.16B for that same tax year

No general Iowa entity-level franchise/net-worth tax on S corps. Iowa does not impose a separate franchise or minimum entity tax on S corporations (a franchise tax applies only to financial institutions on the IA 1120F). The only Iowa entity-level income tax that may apply to a typical S corporation is the elective § 422.16C tax or the mandatory § 422.16B composite remittance for nonresidents.

PART 6 — POST-ELECTION COMPLIANCE

IRS Confirmation

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

Reasonable Compensation (Shareholder-Employees)

☐ Pay shareholder-employees reasonable compensation as W-2 wages before taking distributions. The IRS may recharacterize distributions as wages (subject to employment tax) where compensation is unreasonably low. Document the basis for the salary (duties, time, comparables).

Built-In Gains Tax — 26 U.S.C. § 1374

☐ If the entity converted from C corporation status, gains on assets held at conversion may trigger the corporate-level built-in gains tax if recognized during the 5-year recognition period. Track the net unrealized built-in gain and fair market values at the conversion date.

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

☐ If the S corporation has accumulated C corporation E&P and passive investment income exceeds 25% of gross receipts, a corporate-level tax under § 1375 applies; 3 consecutive years over 25% terminates the S election (§ 1362(d)(3)) — monitor annually

Ongoing Federal and Iowa Filings

☐ File federal Form 1120-S and issue Schedule K-1 to each shareholder annually
☐ File Iowa Form IA 1120S and Iowa Schedule K-1 annually; file the IA PTE-C or remit the § 422.16C tax as applicable
☐ Monitor shareholder eligibility — an ineligible transfer (e.g., to a partnership or nonresident alien) terminates the election
☐ Maintain a single class of stock

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

Voluntary Revocation — § 1362(d)(1)

☐ Shareholders holding more than 50% of the outstanding shares (voting and nonvoting) must consent
☐ File a revocation statement with the IRS Service Center where the original election was filed (no official form; letter format under Treas. Reg. § 1.1362-6(a)(3))
☐ Include the corporation's name, EIN, a statement that it revokes its § 1362(a) election, the number of shares outstanding, and consenting shareholders' signatures and share counts
☐ Effective date: if filed by the 15th day of the 3rd month of the tax year, effective the first day of that year; otherwise the first day of the following year. A prospective date may be specified.

Five-year re-election bar. After a termination or revocation, the corporation generally may not re-elect S status for 5 tax years without IRS consent (§ 1362(g)).

Involuntary Termination — § 1362(d)(2)–(3)

Termination occurs automatically if the corporation:

☐ Ceases to qualify as a small business corporation (e.g., exceeds 100 shareholders, issues a second class of stock, or admits an ineligible shareholder) — effective on the date of the disqualifying event (§ 1362(d)(2))
☐ Has C corporation E&P and passive investment income > 25% of gross receipts for 3 consecutive years (§ 1362(d)(3))

☐ Consider requesting inadvertent-termination relief under § 1362(f) where the disqualification was inadvertent and promptly corrected
