Your clients have been reading headlines about "no tax on tips" and the new senior deduction for weeks. Now they're calling to ask whether they qualify—and you're three weeks out from April 15 with a stack of returns still in progress.
The One Big Beautiful Bill Act introduced several new deductions for 2025, and the questions are piling up faster than the guidance. This article covers the OBBBA provisions your clients are asking about most: the SALT cap increase, the senior deduction, the tip deduction, the overtime deduction, auto loan interest, and how the higher standard deduction changes the itemizing calculation.
The One Big Beautiful Bill Act introduced several new deductions for the 2025 tax year. The biggest changes include a senior deduction of $6,000 per eligible individual for taxpayers age 65 and older, a tip deduction of up to $25,000 for workers in traditionally tipped occupations, an overtime deduction of up to $12,500 for the premium portion of qualified overtime compensation, and a $10,000 deduction for interest on new vehicle loans. The SALT cap also increased to $40,000 for 2025 filings, and standard deduction amounts rose to $15,750 for single filers and $31,500 for married filing jointly.
For tax professionals, the challenge right now is knowing which provisions apply to which clients. Some of the new deductions are above-the-line, meaning they reduce AGI regardless of whether your client itemizes. Others affect Schedule A calculations directly. The distinctions matter when you're advising clients on whether itemizing still makes sense.
The state and local tax deduction has been a sore spot since the Tax Cuts and Jobs Act capped it at $10,000. OBBBA changes that, though not as dramatically as some clients expect.
The SALT cap rises to $40,000 for 2025 filings. The cap covers the combined total of state and local income taxes (or sales taxes, if your client elects that option) plus property taxes. The cap increases by 1% annually through 2029, then reverts to $10,000 beginning in 2030.
The higher cap phases out for taxpayers with MAGI above $500,000 ($250,000 for married filing separately). The cap is reduced by 30% of the amount by which MAGI exceeds the threshold, but never below $10,000. Once MAGI reaches $600,000 ($300,000 for married filing separately), the taxpayer is back to the $10,000 cap—there's no benefit from the increase at all.
So while the increase is substantial, high earners in expensive states may still hit limitations.
The clients who see the biggest benefit tend to share a few characteristics:
Even with the higher SALT cap, pass-through entity tax elections remain valuable for business owners. PTE taxes are deductible at the entity level in 36 jurisdictions, which means they bypass the individual SALT cap entirely.
For clients with significant pass-through income in states offering PTE elections, the workaround often provides greater benefit than the increased individual cap. The two approaches aren't mutually exclusive, but the PTE election typically delivers more savings for business owners in high-tax states.
One of the most-asked-about OBBBA provisions is the new deduction for taxpayers age 65 and older. Unlike the SALT deduction, this one is above-the-line, meaning it reduces AGI regardless of whether your client itemizes.
The eligibility rule is straightforward: your client qualifies if they turn 65 by the end of the tax year. The deduction is available for tax years 2025 through 2028.
For married couples filing jointly, both spouses can qualify if both meet the age threshold. That effectively doubles the benefit when both are 65 or older.
The base deduction is $6,000 per eligible individual. For married filing jointly when both spouses qualify, that's $12,000. However, the deduction phases out for higher-income taxpayers.
The phaseout begins at $75,000 of modified AGI for single filers and $150,000 for joint filers. A single filer with $85,000 MAGI, for example, would see a reduced deduction based on the excess MAGI over the threshold.
Documentation is minimal compared to other deductions:
The "no tax on tips" provision has generated significant media attention. The actual mechanics, though, are more nuanced than the headlines suggest.
The deduction applies to employees and independent contractors who receive tips in nearly 70 listed occupations that "customarily and regularly" received tips before January 1, 2025. Restaurant servers, bartenders, hotel staff, barbers, and hairdressers typically qualify.
Self-employed individuals in specified service trades or businesses as defined under IRC Section 199A are generally ineligible. However, the IRS has issued transition relief for 2025 that treats employees in tipped occupations as eligible regardless of whether the employer is an SSTB. The IRS has indicated that the occupation itself determines eligibility, not just whether the worker happens to receive tips.
Not all gratuities qualify:
The distinction matters because service charges, even when labeled as "gratuity" on a receipt, are technically wages under IRS rules.
The deduction is limited to $25,000 annually. It phases out for taxpayers with modified AGI exceeding $150,000 for single filers or $300,000 for married filing jointly.
Your client reports tip income as usual on Form 4137, then claims the deduction separately. The calculation requires tracking qualified tips specifically, which may require more detailed recordkeeping than some tipped workers have historically maintained.
Here's the part that surprises many clients: the tip deduction provides income tax relief only. FICA taxes, including Social Security and Medicare, still apply to all tip income.
For a client in the 22% marginal bracket claiming the full $25,000 deduction, the federal income tax savings could reach $5,500. But they'll still owe 7.65% in FICA on that same income. The deduction helps, but it doesn't eliminate all taxes on tips.
OBBBA created a new deduction for qualified overtime compensation, and it's one of the four headline provisions your clients are asking about.
The deduction applies to employees who receive overtime compensation required by the Fair Labor Standards Act for hours worked beyond the standard 40-hour workweek. The maximum deduction is $12,500 for single filers and $25,000 for married filing jointly.
The FLSA requirement is a meaningful distinction. FLSA-exempt employees—salaried managers, many professionals—who work overtime don't qualify, even if their employer voluntarily pays extra for those hours.
The deduction phases out for taxpayers with modified AGI exceeding $150,000 for single filers or $300,000 for married filing jointly—the same thresholds as the tip deduction.
Qualified overtime compensation means the premium portion of overtime pay—specifically, the amount that exceeds the regular rate of pay for hours worked beyond 40 in a workweek. For time-and-a-half compensation, the deduction covers only the "half" portion, not the full overtime rate.
For example, a client earning $30 per hour who works 10 overtime hours at time-and-a-half receives $450 in total overtime pay. The deductible amount is $150—the premium portion calculated as $15 per hour (half the regular rate) times 10 hours. The overtime must be properly reported on Form W-2 or Form 1099.
For clients who work multiple jobs or have irregular schedules, tracking which compensation qualifies requires coordination with their employer's payroll records.
OBBBA created a new deduction for interest paid on loans for qualified passenger vehicles. This provision didn't exist before, and it catches many clients by surprise.
The deduction applies to interest on loans used to purchase qualified passenger vehicles. Income limits apply: the deduction phases out starting at $100,000 MAGI for single filers and $200,000 for joint filers.
The vehicle itself has specific requirements. The vehicle must be new—meaning original use begins with the taxpayer—and must have undergone final assembly in the United States. Qualified vehicles include cars, minivans, vans, SUVs, pick-up trucks, and motorcycles with a gross vehicle weight rating under 14,000 pounds. The deduction covers personal use only, not commercial vehicles.
One question worth addressing up front: lease payments don't qualify. The IRS specifically excludes lease payments from the deduction, so clients who lease rather than finance won't benefit from this provision.
Section 70203 provides transition relief for vehicles purchased before the law's enactment. If your client bought a qualifying vehicle and originated a loan within the specified window, they may still claim the deduction even though the purchase predates OBBBA.
The specific dates and requirements are detailed in IRS guidance. Verifying eligibility requires checking both the purchase date and the loan origination date.
The auto loan interest deduction is claimed above the line, reducing AGI directly. Your client will need Form 1098 or equivalent documentation from their lender showing interest paid during the tax year. The maximum deduction is $10,000 annually.
If a qualifying vehicle loan is later refinanced, interest paid on the refinanced amount generally remains eligible for the deduction. That's a detail clients will ask about, particularly those who refinance to secure better rates after the initial purchase.
OBBBA increased standard deduction amounts to $15,750 for single filers and $31,500 for married filing jointly, which changes the math for clients deciding whether to itemize. With 90% of taxpayers claiming the standard deduction under TCJA, the higher standard deduction means some clients who previously itemized may now find it more beneficial, even with the increased SALT cap.
The decision typically comes down to whether mortgage interest, charitable contributions, and the new SALT cap together exceed the standard deduction for your client's filing status.
High-net-worth clients face additional complexity because several OBBBA provisions include income-based phaseouts.
OBBBA modified the Pease limitation under IRC Section 68, which historically reduced itemized deductions for high earners. TCJA suspended it, and OBBBA introduces a new formula—but not for 2025 returns.
Starting with tax years beginning after December 31, 2025, high-income taxpayers will face a smaller reduction calculated as 2/37 of the lesser of their itemized deductions or the amount by which taxable income exceeds certain thresholds. The new formula is less restrictive than the original Pease limitation, but it's worth flagging for clients planning ahead.
Multiple OBBBA deductions share similar phaseout structures for 2025 returns:
For clients near any of the thresholds, timing of income recognition or deductions may affect eligibility.
Most OBBBA deduction changes apply prospectively starting with the 2025 tax year. Amending prior returns to claim the new provisions generally isn't applicable since the deductions didn't exist for earlier tax years.
Clients benefiting from new OBBBA deductions may want to recalculate their estimated payments to avoid overpaying. The senior deduction, tip deduction, and overtime deduction, in particular, can significantly reduce tax liability for clients who haven't accounted for them in their estimates.
