2026 Tax Law Changes Every Preparer Should Review

1. Start with the 2026 inflation adjustments

The IRS adjusts dozens of tax provisions each year. Revenue Procedure 2025-32 contains the detailed tax-year 2026 amounts, and the IRS published a shorter summary for preparers and taxpayers. The tax rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%, but the income ranges assigned to those rates move.

The 2026 standard deduction is:

• $16,100 for single filers and married individuals filing separately.
• $32,200 for married couples filing jointly and qualifying surviving spouses.
• $24,150 for heads of household.

Do not stop at the standard deduction. A complete office update should also load the final bracket thresholds and the current amounts for credits, health and dependent-care benefits, retirement provisions, estate and gift rules, and any limits that matter to the returns your office actually prepares. The right workflow is not memorizing sixty numbers. It is keeping a dated reference sheet tied to the final IRS source.

2. Treat the new individual deductions as real rules, not slogans

The One, Big, Beautiful Bill Act added deductions commonly described as “no tax on tips,” “no tax on overtime,” “no tax on car loan interest,” and a new deduction for seniors. Most of these provisions began in 2025 and continue through 2028. The marketing labels leave out important eligibility limits.

Qualified tips

Eligible employees and self-employed people may deduct up to $25,000 of qualified tips. The IRS says the deduction phases out when modified adjusted gross income exceeds $150,000, or $300,000 on a joint return. The tips must fit the statutory definition, be properly reported, and come from an occupation that qualifies under the IRS rules. Self-employed taxpayers face additional limits, including a limit based on net income from the relevant business.

That means a preparer needs more than a number labeled “tips.” Intake should establish the occupation, how the amount was reported, whether the payment was voluntary, the taxpayer’s filing status, and whether an income phaseout applies.

Qualified overtime compensation

The overtime deduction does not cover every dollar earned during an overtime shift. IRS guidance explains that qualified overtime generally means the portion paid above the regular rate because the Fair Labor Standards Act requires it. One example is the "half" in time-and-a-half pay.

The annual limit is $12,500, or $25,000 on a joint return, with phaseouts beginning above $150,000 of modified adjusted gross income, or $300,000 for joint filers. Preparers should expect reporting to become more structured for tax year 2026, but must use final forms and instructions rather than guessing where an amount belongs.

Qualified passenger-vehicle loan interest

Individuals may be able to deduct up to $10,000 of qualifying interest on a loan for a personal-use passenger vehicle. The IRS conditions include a loan originated after December 31, 2024, a new vehicle whose original use begins with the taxpayer, a lien securing the loan, and final assembly in the United States. A lease does not qualify. The deduction begins to phase out above $100,000 of modified adjusted gross income, or $200,000 on a joint return.

A lender’s year-end number is only the start. The preparer also needs to confirm the vehicle, acquisition date, loan use, personal-versus-business use, and any refinance history.

Additional deduction for seniors

An eligible taxpayer who is age 65 or older may claim an additional $6,000 deduction. Two eligible spouses may each qualify. The deduction begins to phase out above $75,000 of modified adjusted gross income, or $150,000 on a joint return. It is separate from the existing additional standard deduction for age or blindness and is available whether the taxpayer itemizes or claims the standard deduction.

The intake question should ask the taxpayer’s date of birth and marital filing situation, not merely whether someone calls themselves retired.

3. Expect reporting changes, then wait for final forms

The IRS announced that tax-year 2026 reporting would include changes for tips and overtime. That matters because a preparer’s process must eventually connect the source document to the deduction calculation. It does not mean an office should build a permanent worksheet around a draft box number.

Use a three-stage review:

1. Law review: understand who may qualify and which facts control the result.
2. Form review: compare final W-2, 1099, Schedule 1, Form 1040, and related instructions with the prior year.
3. Software review: test a sample return and confirm that diagnostics, worksheets, carryovers, and e-file output match the final instructions.

Save the version and date of every source used in the office update. If guidance changes later, that record makes it easier to identify which returns deserve another look.

4. Turn the law change into an intake and review checklist

A useful annual update changes behavior. Before the first tax-year 2026 return, revise these five parts of the workflow:

• Organizer questions: add direct questions for tips, FLSA overtime, new-vehicle loan interest, age-based deductions, and documents that support each item.
• Document naming: create consistent labels so a reviewer can find the W-2, lender statement, purchase agreement, or occupation evidence behind a claim.
• Review notes: require a short explanation when eligibility depends on a definition that is narrower than everyday language.
• Client explanation: describe the result as a deduction with eligibility rules. Do not repeat a slogan that implies all tips or overtime escape every tax.
• Final-source gate: do not release a return using a new provision until the office has checked final IRS forms, instructions, and current software diagnostics.

Also identify which changes do not belong on every return. A clean checklist should make irrelevant questions easy to skip while preserving the follow-up needed for an affected taxpayer.

5. Use a review rhythm instead of a one-time update

Tax law does not arrive as one perfect packet. Congress changes statutes. Treasury and the IRS issue guidance. Forms move from draft to final. Software vendors implement calculations. A careful preparer checks each layer.

A practical rhythm is:

• Read the statute-level and IRS overview early enough to update training.
• Review final forms and instructions when issued.
• Run controlled test returns before opening the workflow to live clients.
• Subscribe to IRS updates and keep an office change log during filing season.
• Escalate facts outside your training or software support instead of improvising.

The goal is not to sound certain first. It is to be correct when a client’s return is signed.
