Understanding PTET: Foundation & Strategy
What is PTET?
Pass-Through Entity Tax (PTET) elections allow eligible pass-through entities (S-corporations, partnerships, and LLCs taxed as partnerships or S-corps) to pay state income tax at the entity level rather than having owners pay individually. This structure creates a federal deduction for state taxes paid, effectively bypassing the $10,000 SALT cap limitation imposed by the Tax Cuts and Jobs Act (TCJA).
💡 Key Benefit: PTET converts a non-deductible (or limited) personal state tax payment into a fully deductible business expense at the federal level, while owners receive a corresponding credit on their personal state returns.
The SALT Cap Evolution
- Pre-2018: State and local taxes (SALT) were fully deductible on Schedule A
- TCJA (2018-2024): SALT deduction capped at $10,000 per household
- OBBBA (2025-2029): SALT cap increased to $40,000, but phases out for income $500K-$600K
- High Earners ($600K+ MAGI): Still limited to $10,000 SALT cap
- 2030 and Beyond: Cap reverts to $10,000 for all taxpayers
⚠️ 2025 SALT Cap Update (One Big Beautiful Bill Act): The SALT cap was increased to $40,000 for 2025-2029, with 1% annual inflation adjustments. However, this benefit phases out for taxpayers with MAGI between $500,000-$600,000, dropping to the original $10,000 cap above $600,000. PTET remains valuable for high earners above these thresholds.
💡 When PTET Still Matters Most:
- MAGI > $600,000: Full PTET benefit — still limited to $10K personal SALT cap
- MAGI $500K-$600K: Partial benefit — SALT cap phases out, creating "SALT torpedo" marginal rates
- MAGI < $500,000: Reduced benefit — may still benefit if state taxes exceed $40,000
- 2030 Planning: PTET becomes critical again when cap reverts to $10,000
Client Assessment & Eligibility
Ideal PTET Candidates (2025-2029)
| Client Characteristic | Why PTET Benefits | Priority Level |
|---|---|---|
| MAGI > $600,000 | Still limited to $10K personal SALT cap — full PTET benefit applies | 🔴 High |
| MAGI $500K-$600K ("SALT Torpedo" zone) | SALT cap phases out; PTET avoids artificially high marginal rates | 🔴 High |
| High state tax rates (>5%) + MAGI > $500K | Larger absolute dollar benefit from federal deduction | 🔴 High |
| State taxes exceed $40,000 (any income) | PTET captures deduction above new $40K cap | 🟡 Medium |
| Multi-state operations | Can optimize elections state-by-state | 🟡 Medium |
| MAGI < $500K with <$40K state taxes | May not need PTET — evaluate standard SALT deduction first | 🟢 Re-evaluate |
🚨 "SALT Torpedo" Warning: Taxpayers with MAGI between $500,000 and $600,000 face a phaseout that can create effective marginal tax rates as high as 45.5%. PTET elections can help mitigate this by moving state tax payments off the personal return entirely.
Eligibility Requirements Checklist
PTET Benefit Calculation (2025-2029)
Updated Benefit Analysis by Income Level
📊 PTET Benefit Depends on Income Level:
- MAGI ≤ $500K: Personal SALT cap = $40,000 → PTET benefit only on state taxes ABOVE $40K
- MAGI $500K-$600K: Personal SALT cap phases out → PTET provides increasing benefit
- MAGI > $600K: Personal SALT cap = $10,000 → Full PTET benefit on state taxes above $10K
Benefit Comparison: With vs. Without PTET
| Scenario | State Tax | Personal SALT Cap | PTET Benefit | Fed Savings (37%) |
|---|---|---|---|---|
| MAGI $400K | $30,000 | $40,000 | $0 (under cap) | $0 |
| MAGI $400K | $60,000 | $40,000 | $20,000 | $7,400 |
| MAGI $550K (phaseout) | $40,000 | ~$25,000 | $15,000 | $5,550 |
| MAGI $700K | $50,000 | $10,000 | $40,000 | $14,800 |
| MAGI $1,000,000 | $75,000 | $10,000 | $65,000 | $24,050 |
| MAGI $2,000,000 | $150,000 | $10,000 | $140,000 | $51,800 |
⚠️ Key Insight: For clients with MAGI under $500,000 and state taxes under $40,000, PTET may no longer provide a benefit through 2029. However, PTET elections should still be considered for: (1) clients expecting income growth above $500K, (2) state taxes exceeding $40K, and (3) long-term planning for when the cap reverts to $10K in 2030.
✅ 2030 Planning Note: The $40,000 SALT cap is temporary (2025-2029). When the cap reverts to $10,000 in 2030, PTET will again become valuable for ALL clients currently at/above the $10K threshold. Maintain PTET election infrastructure and client awareness now.
Implementation Timeline
Annual PTET Cycle
Q4 Prior Year (Oct-Dec)
Initial client assessment and benefit projections for upcoming year. Review prior year results if applicable.
Q1 (Jan-Mar)
Critical: Many states require elections by March 15 or with first estimated payment. Make elections and first quarterly payment.
Q2 (Apr-Jun)
Second quarterly estimated payment. Review YTD income projections. File extensions if needed.
Q3 (Jul-Sep)
Third quarterly estimated payment. Mid-year benefit review and adjustment.
Q4 (Oct-Dec)
Fourth quarterly payment. Year-end planning. Begin next year assessment. Some states allow late election with timely filed return.
Following Year (Mar-Apr)
File entity return with PTET. Issue K-1s with PTET credit information. Coordinate owner returns for credit claims.
State-by-State Implementation Notes
Key States Quick Reference
| State | Election Deadline | Rate | Payment Timing | Notes |
|---|---|---|---|---|
| California | Original due date (no extensions) | 9.3% | 2 payments: June 15 & original due date | $800 minimum tax still applies |
| New York | March 15 (or entity formation date if later) | 6.85%-10.9% | Quarterly | Progressive rates; NYC add-on available |
| New Jersey | With timely filed return + extensions | 5.675%-10.75% | Quarterly | Made on return; retroactive allowed |
| Illinois | With first estimated payment or return | 4.95% | Quarterly | Flat rate; straightforward implementation |
| Massachusetts | With timely filed return + extensions | 5.0% | Annual | Recent rate reduction; made on return |
| Texas | N/A | N/A | N/A | No income tax - PTET not applicable |
| Florida | N/A | N/A | N/A | No individual income tax - not applicable |
🚨 Important: State PTET rules change frequently. Always verify current deadlines, rates, and requirements with state department of revenue or current tax software before making elections.
Compliance & Documentation
Required Documentation Checklist
Common Pitfalls to Avoid
- Missing Election Deadlines: Many states have non-waivable deadlines - calendar these immediately
- Insufficient Estimated Payments: Underpayment penalties apply - maintain safe harbor
- Owner Return Errors: Credits must be properly claimed on individual returns to avoid double-tax
- Multi-State Complexity: Don't assume all states work the same - each has unique rules
- Basis Adjustments: PTET payments affect owner basis - track properly
- Operating Agreement Updates: Consider whether OA needs modification for PTET elections

✅ Integration with The Eiduk Pathway™: PTET (Strategy #26) works in conjunction with other Phase 4 strategies including State Tax Planning (#27) and pairs well with Phase 1 Reasonable Compensation (#1) analysis to optimize overall tax position. Post-OBBBA, coordinate PTET analysis with income projections to maximize benefit around the $500K/$600K thresholds.
📋 Key Law Reference: One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, modified SALT cap from $10,000 to $40,000 for 2025-2029 with income-based phaseouts. IRS Notice 2020-75 continues to confirm federal deductibility of PTET payments. PTET workaround was NOT restricted by OBBBA.
