For the 2026 tax year, the "One Big Beautiful Bill" (OBBBA) has fundamentally shifted the math for American homeowners. After years of the $10,000 "SALT cap" pushing taxpayers toward the standard deduction, 2026 is officially the year to re-evaluate itemizing.
1. The SALT Cap has Quadrupled: Since the 2017 Tax Cuts and Jobs Act, homeowners were restricted by a $10,000 limit on state and local tax (SALT) deductions. As of the 2026 tax year, that landscape has been transformed.
• The New Limit: The cap has been raised to $40,400 (an inflation adjustment from the $40,000 base set in 2025).
• The Income Threshold: This expanded benefit is available to households with a Modified Adjusted Gross Income (MAGI) of $505,000 or less ($252,500 for married filing separately).
• Why it matters: In mid-to-high tax regions, property taxes and state income taxes frequently exceed $10,000. This new threshold allows the average homeowner to shield significantly more of their income from federal taxes, making homeownership more affordable in high-value markets.
2. The Sunset of Federal "Green" Credits: While the SALT update is a major win, 2026 also brings the official "sunset" of several popular incentives established under previous administrations.
• Expired Sections (25C & 25D): As of January 1, 2026, federal tax credits for solar panels, geothermal heat pumps, battery storage, and high-efficiency HVAC/windows have expired.
• The Strict Deadline: To qualify for the previous 30% credit, equipment must have been fully installed and operational (placed in service) by December 31, 2025.
PSA Advice: If you are planning upgrades this year, focus on the long-term energy savings and potential state-level rebates, as the federal government has shifted these funds toward broader infrastructure projects.
3. The Return of the PMI Deduction: In a significant move to support newer homeowners, the OBBBA has reinstated a popular deduction that had been dormant for years.
• PMI as Interest: Private Mortgage Insurance (PMI) premiums are now officially treated as deductible mortgage interest for the 2026 tax year.
• Eligibility: This applies to homeowners who put less than 20% down on their homes. Like the SALT cap, this is subject to income phase-outs (beginning at $100,000 MAGI), but it provides a vital “hidden” deduction for those who itemize.
