The biggest tax surprises hitting Americans right now (as we file our 2025 returns in the 2026 tax season) come straight from the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025. This massive legislation made many 2017 Tax Cuts and Jobs Act (TCJA) provisions permanent—preventing huge tax increases that loomed at the end of 2025—and introduced fresh, targeted deductions for working Americans, families, seniors, and new car buyers.
The result? Many filers are seeing larger refunds than expected because 2025 withholding tables didn’t fully account for these retroactive changes. The IRS estimates significant tax relief, with some analyses suggesting average refunds could rise by hundreds (or even up to $1,000 for certain groups) due to the $129 billion in individual tax cuts for 2025 alone.
But surprises cut both ways: pleasant windfalls for qualifiers, plus paperwork headaches from the new Schedule 1-A (the dedicated form for claiming these four main temporary deductions: tips, overtime, car loan interest, and the senior bonus). Here’s a breakdown of the top surprises shaking up this filing season:
1. No Tax on Tips (Deduction for Qualified Tips)
Workers in customary tipped occupations (e.g., servers, bartenders, rideshare drivers, delivery folks—IRS list published by October 2025) can deduct qualified tips reported on W-2, 1099, or Form 4137. This runs through 2028.
Surprise factor: Many in the service industry are discovering thousands in extra deductions they never anticipated, leading to bigger refunds. But strict reporting is key—some face transition relief confusion or miss out if tips weren’t properly documented.
2. No Tax on Overtime (Deduction for Qualified Overtime Pay)
The “premium” portion of overtime (e.g., the extra half in time-and-a-half under FLSA) is deductible, up to $12,500 ($25,000 joint) for 2025–2028. Reported on W-2/1099. Phases out at higher incomes (starts around $150k single/$300k joint).
Surprise factor: Hourly workers and self-employed folks are shocked by the savings—especially since employers had to report it specially. Transition guidance helped 2025, but not everyone tracked it right, causing some to amend or miss claims.
3. Car Loan Interest Deduction (Up to $10,000)
Interest on loans for new, personally used vehicles (cars, trucks, SUVs, motorcycles) with final assembly in the U.S., purchased after Dec. 31, 2024, is deductible up to $10k/year through 2028. Lenders report via statements or online portals (transition relief for 2025). Phases out starting at $100k single/$200k joint MAGI.
Surprise factor: This “no tax on car loan interest” promise is delivering for many new buyers, but eligibility hurdles (new only, U.S.-assembled, not leases/used) leave some disappointed. Lenders’ reporting delays or missing 1098-style forms add confusion—check your portal!
4. Extra $6,000 Deduction for Seniors (65+)
An additional $6,000 deduction (per person—$12k if both spouses qualify) on top of the regular senior standard deduction boost, for 2025–2028. Phases out at lower incomes ($75k single/$150k joint).
Surprise factor: Retirees and near-retirees are thrilled as it stacks with everything else, often pushing refunds higher. Many heard hype (”$6k just for being old”), but it’s real and above-the-line—yet phaseouts catch higher earners off guard.
5. Higher SALT Deduction Cap ($40,000)
The state and local tax deduction limit jumped from $10,000 to $40,000 (with phaseout starting at $500k MAGI), through 2029 (reverts after).
Surprise factor: Itemizers in high-tax states like Illinois, New York, and California (hello, Chicago!) are suddenly deducting way more— a massive win after years of caps limiting relief.
6. Bigger Standard Deduction and Other Family Boosts
The 2025 standard deduction got an extra bump (e.g., ~$31,500 joint in some estimates), plus permanent lower TCJA rates/brackets and Child Tax Credit enhancements in play.
Surprise factor: Middle-income families see combined effects leading to larger refunds—especially with over-withholding early in 2025.
Other quick hits: Expanded adoption credits, Trump Accounts for newborns (with $1,000 seed money in some cases), but also cuts to certain energy credits and new complexities.
This 2026 filing season is one of the trickiest in years—new forms, eligibility rules, phaseouts, and retroactive tweaks mean more errors or missed opportunities. If you tipped, worked overtime, bought a qualifying new car in 2025, or are 65+, review Schedule 1-A closely (available on IRS.gov). Many qualify for real savings, but double-check to avoid audits or amendments.
