PTET Elections Still Matter: How NC (and CA) S Corps / Partnerships Can Ease the Federal SALT Cap—Compliance Planning

Author: Gloria Liu, CPA ｜ YCL Tax, Accounting & Advisory

Bottom line in one breath

If you are a North Carolina S corporation shareholder or partner / LLC member taxed as a partnership—especially in Cary / RTP—or you also own a California pass-through: even though the federal state-and-local tax (SALT) itemized deduction limit rose to about $40,000 starting in 2025, North Carolina’s Taxed PTE (Taxed S Corporation / Taxed Partnership) election and California’s PTE elective tax can still reduce pressure from the individual SALT cap by paying state income tax at the entity and deducting it for federal purposes at the entity. Whether to elect, estimate, and file for 2025–2026 is a compliance-planning question—not a default “always elect” or “always drop.”

News background

The 2017 TCJA capped the individual itemized deduction for state and local taxes at $10,000 ($5,000 MFS). Many states then created pass-through entity (PTE) entity-level income tax elections: the partnership or S corporation pays state tax; owners receive a state deduction or credit. Federally, IRS Notice 2020-75 states that qualifying entity-level state income tax payments are generally deductible in computing the partnership’s or S corporation’s federal income and are not limited by the individual SALT cap (taxpayers may rely on the Notice; final-regulation status 待核 / to confirm).

North Carolina, beginning with Session Law 2021-180, lets eligible S corporations and partnerships elect to be a Taxed PTE. The 2023 SALT Workaround Update (including S.L. 2023-12) narrowed the taxable base (generally North Carolina–attributable income only) and tightened when elections may be made or revoked. California continues a 9.3% PTE elective tax for tax years beginning before January 1, 2031. The One Big Beautiful Bill Act (OBBBA, P.L. 119-21), signed July 4, 2025, raised the individual SALT cap to $40,000 ($20,000 MFS) and reduces that cap for higher MAGI—but public analyses generally conclude it did not eliminate the PTET federal deduction path. For Cary/RTP owners, the live question is: after a higher cap, is the NC election still worth it—and what about California?

Old vs. new rules

1. Federal individual SALT: Prior law (2018–2024) capped the deduction near $10,000. Under OBBBA, for 2025 itemizers may claim up to about $40,000 ($20,000 MFS); the maximum is reduced when MAGI exceeds about $500,000 ($250,000 MFS) (IRS-verified). Annual 1% indexing through 2029 and a possible return to $10,000 in 2030 follow IRC §164(b)(7) and later IRS releases (待核 for exact indexed tiers).

2. Federal PTET path: Qualifying state income taxes paid at the entity level remain, under Notice 2020-75, generally deductible in computing entity federal income and outside the owner’s personal SALT limit; OBBBA is widely described as leaving that path intact (final regs / details 待核).

3. North Carolina Taxed S Corporation (G.S. 105-131.1A): Elect on a timely filed Form CD-401S. Tax is at the individual rate under G.S. 105-153.7—4.25% for tax years beginning in 2025, 3.99% for tax years after 2025 (NCDOR rate schedules). For years beginning on or after January 1, 2023, the base is generally each shareholder’s pro rata share of income or loss attributable to North Carolina.

4. North Carolina Taxed Partnership (G.S. 105-154.1): Elect on a timely filed Form D-403 (Taxed Partnership Yes/No). Same rate and (from 2023) NC-attributable base. Publicly traded partnerships under IRC §7704(c) and partnerships with disallowed partner types cannot elect; the 2023 updates expanded eligible partner categories (certain trusts, partnerships, and corporate partners—follow the current statute).

5. NC election timing (cite carefully): The election is for the year covered by the return and must be made by the due date including extensions. For tax years beginning on or after January 1, 2023, an S corporation or partnership may not make or revoke the election after the return is filed. An election on a late-filed return is generally invalid. Owner deductions depend on the entity paying the tax; if a tax debt remains unpaid 60 days after a collection notice, owners may lose the corresponding deduction.

6. NC owner side: Owners deduct the share of income included in the Taxed PTE’s NC taxable income and add back loss shares (G.S. 105-153.5(c3) mechanics); the entity reports via NC K-1. A Taxed PTE that reasonably expects at least $500 of NC income tax must pay estimated tax in the manner of a C corporation (calendar installments generally April 15, June 15, September 15, December 15; vouchers CD-429 PTE / NC-40 PTE).

7. California PTE (brief): 9.3% of qualified net income; elect on a timely filed original return with FTB 3804—not on an amended return; owners claim credit on FTB 3804-CR (up to 5-year carryover). Payment 1 is due by June 15 of the election year (greater of $1,000 or 50% of prior-year PTE tax); Payment 2 is due by the original return due date without regard to extension. For 2026–2030, a short or missed June 15 payment can still allow an election, but owners must reduce their credit by 12.5% of their share of the unpaid June 15 amount (FTB).

8. Why PTET can still matter after a ~$40k cap: Individual SALT remains capped (and phased down for high MAGI). Property tax, state income tax, and other SALT items can still fill the bucket. PTET moves business income–related state income tax into an uncapped entity-level federal deduction. California’s 9.3% rate is often more sensitive; North Carolina’s lower rate still requires case-by-case modeling with property tax, multi-state income, and MAGI.

Self-check: are you affected?

1. You own a North Carolina S corporation or partnership / LLC taxed as a partnership that must file CD-401S or D-403 (investment partnerships not “doing business” in NC generally cannot elect).

2. You itemize, and state income tax plus property tax (and other SALT) approach or exceed the federal SALT cap—or your MAGI is in the SALT phase-down zone.

3. You are deciding whether to check Taxed PTE for 2025 / 2026, or whether to keep CD-429 PTE / NC-40 PTE estimates flowing.

4. You also have a California partnership or S corporation and must track FTB 3804, the June 15 first payment, and 3804-CR.

5. You have multi-state operations, nonresident owners, or upper-tier partnership / corporate partners—eligibility and base rules are more complex and need a qualification screen first.

Simplified example (illustrative only; ignores credits, expense allocation, QBI, AMT, etc.)

Assume a Cary couple filing jointly with about $400,000 of NC-attributable operating income from an NC S corporation, plus material property taxes. Calendar-year corporation, 2025 rate 4.25%, election and payment requirements met:

1. No Taxed PTE: State income tax largely sits at the individual level and, together with property taxes, competes for the federal SALT cap (~$40,000 for 2025; possibly reduced at high MAGI). Amounts above the cap are not deductible federally.

2. With Taxed PTE: The entity pays roughly $17,000 of NC entity tax on that base ($400,000 × 4.25%, illustrative). That amount is generally deducted in computing federal entity income, reducing what flows to Schedule E. On the NC individual return, the owners deduct the income share already taxed in the entity base (avoiding state-level double counting), reconciling to the NC K-1.

3. If the family also has a California partnership: California may tax qualified net income at 9.3% under a PTE election, with owners claiming 3804-CR; federal entity-level deduction may likewise apply if election and payment rules are met.

Which path fits depends on MAGI, itemizing, property-tax load, multi-state credits, and cash flow—there is no single answer for every owner.

Action items and timeline

1. Now (September 2026): Inventory whether 2025 was elected and whether estimates were adequate; reconcile CD-401S / D-403 and NC K-1 so owner deductions match tax actually paid.

2. 2025 filing season (including extensions): If the NC entity return is not yet filed, finish the elect / don’t-elect model before submission—once filed, the election cannot be changed (2023+ rule). Calendar-year Form D-403 without extension is generally due April 15; a valid federal automatic extension, properly indicated on the NC return, can extend the filing date—but a late return generally cannot cure a missed election.

3. Calendar year 2026: If you expect to elect and NC tax ≥ $500, pay quarterly estimates (~4/15, 6/15, 9/15, 12/15) and update owners’ personal estimates so they do not still assume the old owner-level pattern.

4. California entities: Fund Payment 1 by June 15, 2026; pay the balance by the unextended original due date and attach FTB 3804; owners prepare 3804-CR. If June 15 is short, understand the 12.5% credit haircut.

5. Re-model annually: The federal SALT cap, NC’s rate (3.99% after 2025), and your income mix change the election’s relative value—put it on the yearly compliance-planning checklist rather than “set once for five years.”

What YCL can do

1. North Carolina Taxed S Corporation / Taxed Partnership eligibility screening and election modeling (federal SALT + NC rate + estimate cash flow).

2. CD-401S / D-403, NC K-1, and owner Form D-400 consistency checks, plus the 60-day unpaid-tax rule’s effect on owner deductions.

3. Estimate calendars (CD-429 PTE / NC-40 PTE) coordinated with personal estimated tax.

4. California FTB 3804 / 3893 / 3804-CR timelines and a first-pass multi-state comparison alongside—not instead of—the NC plan.

5. Cross-border coordination: YCL maintains offices in Cary, NC (serving RTP) and Shanghai; CPA Chenchen Liu and Gloria support Chinese-speaking S corp / partnership owners with bilingual compliance planning.

FAQ

Q: The federal SALT cap is already about $40,000—do we still need North Carolina’s Taxed PTE?

A: Not always. After the higher cap, some mid-income owners with modest combined state income and property taxes see a smaller marginal benefit. High MAGI (SALT phase-down), large pass-through income, or California’s 9.3% rate often still favor entity-level planning. Compare with numbers—don’t decide by slogan.

Q: What is the latest we can decide on the NC election—and can we change it?

A: Make it on a timely filed return by the due date including extensions. For tax years beginning in 2023 or later, once the return is filed, you cannot make or revoke the election. An election on a late return is generally invalid. Align shareholders / partners in writing before e-file.

Q: If the entity pays Taxed PTE tax, do owners skip North Carolina individual returns?

A: Resident owners usually still file, but may deduct income shares already taxed in the entity base. Certain nonresidents whose only NC income is the pass-through share, and whose entity paid as required, may be relieved from filing under administrative rules—follow current NCDOR guidance and all of your NC-source facts; do not assume.
