🚨
Active Law — Tax Year 2025
The One Big Beautiful Bill Act was signed into law July 4, 2025. Key provisions are retroactive to January 1, 2025. This is not a future change. It affects returns being filed right now in the current filing season.
📋 From the Desk of Ralph Martinez
Every few years a major tax law changes the conversations you have at your desk. This is one of those years. Tips are now deductible for qualifying workers. Overtime is now deductible for eligible employees. There is a new car loan interest deduction. There is a new senior deduction. The Child Tax Credit went up. Know all of it before your first client sits down.

The Changes That Affect Your Clients Most
💵
1. Tip Income Deduction
Tax years 2025 through 2028
2025 NOW

Workers in occupations that customarily and regularly receive tips may deduct their qualified tip income from federal taxable income. Tips must still be reported on the return first — the deduction then reduces taxable income. The net result for many tipped workers: little or no income tax on tip earnings.

Qualifying occupations include food service workers, bartenders, salon and barber workers, hotel and hospitality staff, and similar service roles. The IRS maintains the qualifying occupation list — check IRS.gov before filing.

Note: This provision expires after tax year 2028 unless extended by Congress. It applies to employees, not self-employed individuals. Tips must still be fully reported — the deduction is applied on Form 1040 after reporting.

⏱️
2. Overtime Pay Deduction
Tax years 2025 through 2028
2025 NOW

Eligible employees may deduct the qualified overtime premium — specifically, the portion of overtime pay that exceeds the employee’s regular rate of pay. This is the “time-and-a-half” premium above the base hourly rate, not the full overtime paycheck. Overtime pay must still be reported as income on the W-2; the deduction is applied separately to reduce taxable income.

Practical example: If a client earns $20/hr and receives $30/hr for overtime, the deductible premium is the extra $10/hr — not the full $30/hr. You need the client’s pay stubs or a letter from their employer to identify the premium amount. The W-2 does not separate this.

Income limits apply — higher earners phase out of this deduction. Check IRS guidance for current thresholds before filing.

Note: Expires after tax year 2028 unless extended by Congress. Applies to employees receiving overtime under the Fair Labor Standards Act. Does not apply to self-employed individuals.

3. Child Tax Credit Increased to $2,200
Tax years 2025 and 2026
2025 NOW

The Child Tax Credit increased from $2,000 to $2,200 per qualifying child under age 17 for tax years 2025 and 2026. The Additional Child Tax Credit (refundable portion) remains available and is indexed for inflation. Verify your software reflects the updated amount before filing any return with a child credit.

👴
4. New Senior Deduction — $6,000
Tax years 2025 through 2028 · Age 65 or older
2025 NOW

Taxpayers who are 65 years of age or older receive an additional $6,000 deduction on top of their regular standard deduction. For married couples where both spouses are 65 or older, the combined additional deduction is $12,000. This stacks on top of the existing age-related standard deduction add-on already in the tax code.

Income phase-outs apply for higher-income seniors. For most retirees on Social Security or pension income in your market, the full deduction is available. Ask every client their age before completing the return.

Note: Expires after tax year 2028 unless extended. Check IRS guidance for the exact phase-out thresholds.

5. SALT Deduction Cap Raised to $40,000
For incomes under $500,000 · Through 2029
2025 NOW

The State and Local Tax (SALT) deduction cap increased from $10,000 to $40,000 for taxpayers with income under $500,000. This only matters for clients who itemize deductions. Most of your South Shore clients take the standard deduction and are unaffected. If a client has significant property taxes and was previously itemizing, recalculate to see if itemizing now makes sense.

Note: This cap reverts to $10,000 in 2030 unless Congress acts again.

🚗
6. Car Loan Interest Deduction
Tax years 2025 through 2028 · New U.S.-assembled vehicles
2025 NOW

Taxpayers may deduct up to $10,000 of qualified interest paid on a loan for a new, U.S.-assembled vehicle. The vehicle must be purchased new — used vehicles do not qualify. The deduction is taken on the federal return and reduces taxable income.

Income limits (MAGI phase-out):

  • Single filers: phase-out begins at $100,000 MAGI
  • Married filing jointly: phase-out begins at $200,000 MAGI

For most working-class clients in South Shore — warehouse workers, gig drivers, tradespeople — income levels are typically within the qualifying range. Ask about any new vehicle purchases and whether the client is paying loan interest on it.

Note: Expires after tax year 2028 unless extended. Applies to new vehicles assembled in the United States. Check IRS guidance for the definition of “U.S.-assembled” and any additional qualifying criteria before filing.

7. Clean Energy Credits — Key Dates and Expirations
Various expiration dates — see below
EXPIRING

Several clean energy tax credits created by the 2022 Inflation Reduction Act have been eliminated or significantly curtailed, with different credits expiring on different dates:

  • Clean vehicle credits (new and used EVs) — end after September 30, 2025
  • Residential clean energy credit (solar panels, battery storage) — ends after December 31, 2025
  • Energy efficient home improvement credit (heat pumps, windows, doors) — ends after December 31, 2025
  • Alternative fuel vehicle refueling property credit — ends after June 30, 2026
  • Commercial clean vehicle credit — ends after June 30, 2026

Transition rules may apply for purchases that were in progress or contracted before the cutoff dates. Do not assume a credit is unavailable without checking the specific date and whether a transition exception applies.

Before filing any return with an energy credit: verify the purchase date against the applicable credit’s expiration date using IRS.gov guidance. Rules are still being finalized.

New Questions to Ask Every Client This Season
📋
Add These to Your Client Intake
“Did you earn any tips at your job this year?” — tip deduction
“Did you work any overtime? Do you have pay stubs showing the overtime amount?” — overtime deduction
“Are you 65 or older?” — senior deduction
“Did you buy an electric vehicle or make energy-efficient home improvements this year?” — those credits are likely gone
“Do you pay significant state or local taxes and do you usually itemize?” — SALT cap raised
⚠️
⚠️ Common Beginner Mistake
Preparing 2025 returns exactly the same as 2024 without asking about tips, overtime, and the senior deduction. These provisions directly affect the most common client types in a real tax office. Missing them costs your client real money and means your return is incomplete.
🕐
🕐 Slow Down & Check Before Filing
IRS guidance on the tip deduction and overtime deduction is still being finalized. The law is new. Always check IRS.gov for the most current instructions, qualified occupation lists, and phase-out thresholds before filing any return that uses these deductions.
