Your clients are asking about tips, overtime, and the new standard deduction.

If you do not have the answers ready, that gap shows.

The 2025 tax law changed more than most preparers realize. Twelve major provisions. New phaseout thresholds. A California non-conformity issue most guides skip entirely.

This is the reference that closes that gap.

What's Inside

Permanent TCJA Rate Extension The OBBBA made the TCJA individual income tax brackets permanent. Rates run 10% to 37%. This guide explains what that means for your clients and why the sunset that never happened still matters for planning.

2025 Standard Deduction Amounts All three filing statuses covered with the exact figures:

• Single / MFS: $15,750
• Married Filing Jointly / QSS: $31,500
• Head of Household: $23,625

Indexed annually via chained CPI.

Temporary Senior Deduction (2025 to 2028) An additional $6,000 deduction for individuals age 65 and older, up to $12,000 for MFJ. Phaseout begins at $75,000 MAGI for single filers and $150,000 for joint filers. Valid SSN required. Reported on Schedule 1-A, Part V.

Child Tax Credit Increase Credit rises to $2,200 per qualifying child, effective after December 31, 2024. The refundable portion is indexed starting 2025. Valid SSN required for the child and the taxpayer.

SALT Deduction Cap Update Cap increases to $40,000 for 2025. Reverts to $10,000 in 2030. MAGI limit applies at $500,000 for MFJ filers. The guide covers exactly when it makes sense to itemize now under the new threshold.

No Tax on Tips and No Tax on Overtime Two of the most-asked-about provisions in the OBBBA, explained side by side:

• Tips: up to $25,000 deduction for qualifying occupations, phaseout begins at $150,000 MAGI single / $300,000 MFJ
• Overtime: up to $12,500 single / $25,000 MFJ, FLSA-required pay only, same phaseout thresholds
• W-2 reporting for 2025 is in transition. The guide explains how to substantiate both deductions without a dedicated box on the form.

Car Loan Interest Deduction (2025 to 2028) Up to $10,000 deductible on qualified passenger vehicle loan interest. New vehicles only. US-assembled only. VIN documentation required. Phaseout begins at $100,000 MAGI single / $200,000 MFJ.

Trump Accounts for Minors A new modified IRA for children born 2025 to 2028. The Treasury makes a $1,000 initial deposit. Annual contribution limit is $5,000. Tax-deferred until age 18. 12-month waiting period applies.

Adoption Credit Enhancements The first $5,000 of the adoption credit is now refundable. Remaining balance is nonrefundable with carryforward. Indexed starting 2025.

Estate and Gift Tax Exemption Raised to $15 million. Indexed starting 2026. Permanently extends the TCJA threshold.

Green Energy Credits: What Is Ending and When Clean vehicle credits expire after September 30, 2025. Home energy and residential credits expire after December 31, 2025. Alt fuel, 179D, 45L, and clean electricity credits expire after June 30, 2026. The guide gives you the full timeline.

Form 1099-DA: Digital Asset Reporting Mandatory gross proceeds reporting started January 1, 2025. Cost basis reporting becomes mandatory in 2026 for assets acquired after 2025. Applies to crypto, NFTs, and digital asset sales. This section covers what brokers must report and when.

California Non-Conformity: The Section Most Guides Skip California is not following the OBBBA. The guide covers every provision California rejected and what it means for your state filers:

• Bonus depreciation: California does not allow it
• Section 179: California caps at $25,000
• QBI Deduction (20%): California does not allow it
• Tips and overtime deductions: California requires addback, eliminating the federal benefit on the state return
• 529 Plans: California taxes K-12 withdrawals and Roth rollovers and adds penalties
• Disaster losses: California does not follow the federal non-itemizer deduction

Bottom line for California clients: federal savings do not automatically carry to the state return.

Frequently Asked Questions

1. Does the tips deduction apply even if my client does not itemize? Yes. The tips deduction is an above-the-line deduction, meaning it reduces your client's AGI regardless of whether they itemize or take the standard deduction. Your client does not need to itemize to benefit.

2. What is the exact 2025 standard deduction for someone filing single? $15,750. For married filing jointly, it is $31,500. For head of household, $23,625. These amounts are indexed annually via chained CPI.

3. My client earns $160,000. Do they still qualify for the overtime deduction? Partially. The phaseout begins at $150,000 MAGI for single filers. For every $1,000 above the threshold, the deduction is reduced by $100. At $160,000, a single filer with $12,500 in overtime would see a $1,000 reduction. The guide walks through how to calculate the phaseout correctly.

4. Does California non-conformity affect tips and overtime deductions? Yes. California requires taxpayers to add back those deductions on the state return. Your California clients will not receive the federal benefit on their state filing, even if they fully qualify at the federal level.

5. When does the SALT cap revert back to $10,000? In 2030. The increased $40,000 cap applies to tax years 2025 through 2029. Congress would need to act before then to prevent it from reverting.

6. What is the Trump Account and who qualifies for the $1,000 deposit? It is a new modified IRA available for children. The US Treasury makes a $1,000 initial deposit for children born between 2025 and 2028. Families can contribute up to $5,000 per year. The account grows tax-deferred until the child turns 18. Eligibility requirements apply.

7. Is the car loan interest deduction available for used vehicles? No. Only new vehicles qualify. The vehicle must also be assembled in the United States. A VIN number is required for documentation. The deduction cap is $10,000 and applies through 2028.

8. Where do I find the phaseout thresholds for tips and overtime in one place? This guide. Both deductions share the same phaseout structure: begins at $150,000 MAGI for single filers and $300,000 for MFJ. Every threshold, cap, and expiration date is listed clearly so you do not have to cross-reference multiple IRS notices.
