The SALT Deduction Cap: Strategies for High Earners to Navigate the $10,000 Limit
CORE INSIGHTS
- The Cap Limit: The TCJA limits federal deductions for State and Local Taxes (SALT) to $10,000 annually, penalizing residents of high-tax states.
- PTE Solution: Business owners can bypass this cap using the Pass-Through Entity (PTE) Tax Election, converting personal taxes into fully deductible business expenses.
- Bunching Strategy: W-2 earners can optimize deductions by “bunching” property tax payments into alternating years to exceed the standard deduction threshold.
For high-net-worth individuals in states like California or New York, the SALT deduction cap creates a significant “Tax Hole.” Data confirms that the $10,000 limit forces millions in state taxes to be paid with post-federal-tax dollars. However, strategic planning—specifically via business structuring and payment timing—can legally recover these lost deductions.
Consider a business owner in California with $500,000 income and a $46,500 state tax bill.
• Standard Filing: Only $10,000 is deductible. $36,500 of state tax generates zero federal benefit.
• PTE Election: The business pays the full $46,500. This entire amount reduces federal K-1 income.
Result: At a 35% bracket, the PTE election generates an immediate $12,775 federal tax savings.
Visualizing the “Tax Drag” of the Cap
Data illustrates the disparity between actual state tax liability and the allowable federal deduction, highlighting the necessity of mitigation strategies.

Expert Insight:
The SALT cap effectively raises the Effective Tax Rate for coastal residents. While the limitation is set to expire after 2025, waiting is not a strategy. Investors must actively seek to reclassify income or bundle deductions to optimize Tax Efficiency in the current tax years.
Comparison of Mitigation Strategies
| Strategy | Mechanism | Ideal For | Complexity |
|---|---|---|---|
| Standard Deduction | Accept fixed deduction ($29,200) | Low SALT liability | Low |
| Bunching Strategy | Pay 2 years of property tax in 1 year | W-2 Employees / Retirees | Medium |
| PTE Election | Pay state tax at Entity Level | Business Owners / Partners | High |
Strategic Action Steps for Execution
If you own an S-Corp, Partnership, or LLC taxed as such, consult a CPA immediately. Over 30 states now offer a PTE tax workaround that allows full deductibility.
W-2 earners should double up property tax payments in a single tax year (pay Jan 2026 bill in Dec 2025). This pushes total itemized deductions above the Standard Deduction threshold.
For remote workers or retirees, the ultimate SALT cap solution is relocating to a 0% income tax state (e.g., Texas, Florida, Nevada), eliminating the liability entirely.
The Bottom Line: Who Should Choose What?
- Business Owners: Must prioritize the PTE Election. It is the single most effective tool for bypassing the cap.
- W-2 High Earners: Focus on Bunching charitable and tax payments or consider municipal bonds to reduce overall taxable income.
