2025 Tax Updates Guide | OBBBA Changes for Tax Professionals

The One Big Beautiful Bill Act passed in July 2025.

The deductions are real. The phaseouts are real. And the confusion is real too.

Clients are walking in asking about tips, overtime, SALT, and senior deductions. The W-2 forms were not updated to separate any of it. The IRS issued transition relief and scattered guidance across multiple notices. And the filing season opened January 26, 2026.

That is the problem this guide solves.

Who This Is For

This guide was built for:

• Tax preparers and EROs heading into the 2026 filing season with OBBBA questions they have not fully resolved
• Professionals serving tipped workers, hourly employees, seniors, and families who will be asking about every new provision
• Individual taxpayers who want to understand what changed, what they qualify for, and what to bring to their preparer
• Anyone who searched the IRS website and left with more questions than answers

If you have a client whose W-2 does not show tips or overtime separately, or you are unsure whether the senior deduction stacks on top of the standard deduction, this guide gives you a clear answer.

What You Will Be Able to Do

After using this guide, you will:

• Know exactly which deductions apply to which clients and how to calculate each one correctly
• Identify the phaseout thresholds for tips, overtime, SALT, and the senior deduction before you ever touch a return
• Understand what documentation to ask clients for when their W-2 does not break out the numbers
• Explain the new provisions to clients in plain language without second-guessing yourself
• File 2025 returns with confidence that no deduction or credit was missed or misapplied

What's Inside

No Tax on Tips and No Tax on Overtime Both deductions explained side by side. Who qualifies, what the income phaseouts are, how to calculate the deductible amount when the W-2 does not break it out, and what the documentation standard is for the 2025 transition year. Covers tipped occupation rules and the FLSA overtime definition so you know exactly which clients are eligible.

Senior Deduction (65+) The $6,000 single or $12,000 joint deduction that applies on top of the standard deduction for qualifying taxpayers. Phaseout thresholds clarified. Covers who qualifies, how to claim it, and how it interacts with the existing additional standard deduction for seniors.

Increased SALT Cap The cap increased from $10,000 to $40,000 for 2025. But phaseouts start at $500,000 MAGI. This section explains exactly how the phasedown works, who it actually helps, and when it is worth switching from standard to itemized.

Car Loan Interest Deduction Up to $10,000 deductible for interest on qualifying loans. Loan must originate in 2025. Vehicle must be assembled in the United States. Rules for verifying vehicle eligibility covered.

Child Tax Credit and Standard Deductions Updated Child Tax Credit of $2,200 per qualifying child, refundable up to $1,700. Full 2025 standard deduction table by filing status. Single: $15,750. Married Filing Jointly: $31,500. Head of Household: $23,625.

IRS Filing Season and Reporting Updates Filing season opened January 26, 2026. Paper refund checks are being phased out. Digital asset transactions now require Form 1099-DA. IRS Online Account guidance included.

Why This Guide Exists

The IRS has the information.

It is spread across Notice 2025-69, draft forms, transition relief announcements, FAQ pages, and guidance updates that kept coming through the end of 2025. It is written for people who already know the system. And it leaves out the practical decisions that every preparer has to make when a real client is sitting across from them.

This guide puts every OBBBA provision in one place. Phaseouts defined. Documentation standards clarified. Filing updates included. Built for the 2026 filing season specifically.

Guessing costs money.

Do it right from day one.

Frequently Asked Questions

1. Is the no tax on tips deduction available if I take the standard deduction? Yes. Both the tips deduction and the overtime deduction are available to taxpayers whether they itemize or take the standard deduction. They are above-the-line deductions that reduce taxable income directly.

2. What if my client's W-2 does not show tips or overtime separately? The IRS issued transition relief for 2025. Workers can use Form W-2 Box 7, Form 4070 records, or pay stubs to substantiate the deductible amount. The guide explains each acceptable method clearly.

3. Can a self-employed person claim the overtime deduction? No. The qualified overtime deduction applies only to employees covered by the Fair Labor Standards Act. Independent contractors paid on a 1099 do not qualify for the overtime deduction. The tips deduction works differently and self-employed individuals in qualifying occupations may be eligible.

4. Does the senior deduction apply on top of the standard deduction? Yes. The $6,000 single or $12,000 joint senior deduction for taxpayers age 65 and older is separate from and in addition to the standard deduction. It is not an either-or choice.

5. What vehicles qualify for the car loan interest deduction? The loan must originate in 2025. The vehicle must be a qualifying passenger vehicle assembled in the United States. The guide covers how to verify assembly location using the VIN and NHTSA resources.

6. Does the SALT deduction only help if I itemize? Yes. The SALT deduction is an itemized deduction. Taxpayers who claim the standard deduction cannot also claim SALT. With the cap now at $40,000, more filers in high-tax states may find it worthwhile to itemize. The guide walks through when the math favors switching.

7. What is Form 1099-DA and who needs to file it? Form 1099-DA is the new IRS form for reporting digital asset transactions. It applies to 2025 activity. Any taxpayer who bought, sold, or exchanged cryptocurrency or other digital assets in 2025 needs to ensure this is reported correctly.

8. Does the overtime deduction apply to the full overtime check or just part of it? Only the premium portion. That is the extra half in time-and-a-half pay. If regular pay is $20 per hour and overtime pay is $30, only the $10 difference per hour is deductible. The guide explains the calculation method for every scenario the IRS addressed in Notice 2025-69.
