If you make quarterly estimated tax payments, the amount you owe may be affected by the One Big Beautiful Bill Act (OBBBA). The law, which was enacted on July 4, 2025, introduces new deductions, credits and tax provisions that could shift your income tax liability this year.

Tax basics

Federal estimated tax payments are designed to ensure that certain individuals pay their fair share of taxes throughout the year.

If you don’t have enough federal tax withheld from your paychecks and other payments, you may have to make estimated tax payments. This is the case if you receive interest, dividends, self-employment income, capital gains, a pension or other income that’s not covered by withholding.

Individuals generally must pay 25% of a “required annual payment” by April 15, June 15, September 15, and January 15 of the following year, to avoid an underpayment penalty. If one of those dates falls on a weekend or holiday, the payment is due on the next business day.

The third installment for 2025 is due on Monday, September 15. Payments are made using Form 1040-ES.

Amount to be paid

The required annual payment for most individuals is the lower of 90% of the tax shown on the current year’s return or 100% of the tax shown on the return for the previous year. However, if the adjusted gross income on your previous year’s return was more than $150,000 ($75,000 if you’re married filing separately), you must pay the lower of 90% of the tax shown on the current year’s return or 110% of the tax shown on the return for the previous year.

Most people who receive the bulk of their income in the form of wages satisfy these payment requirements through the tax withheld from their paychecks by their employers. Those who make estimated tax payments generally do so in four installments. After determining the required annual payment, divide that number by four and make four equal payments by the due dates.

But you may be able to use the annualized income method to make smaller payments. This method is useful to people whose income flow isn’t uniform over the year, perhaps because of a seasonal business. For example, if your income comes exclusively from a business operated in a resort area during June, July and August, no estimated payment is required before September 15.

The underpayment penalty

If you don’t make the required payments, you may be subject to an underpayment penalty. The penalty equals the product of the interest rate charged by the IRS on deficiencies times the amount of the underpayment for the period of the underpayment.

However, the underpayment penalty doesn’t apply to you if:

• The total tax shown on your return is less than $1,000 after subtracting withholding tax paid;
• You had no tax liability for the preceding year, you were a U.S. citizen or resident for that entire year, and that period was 12 months;
• For the fourth (January 15) installment, you file your return by that January 31 and pay your tax in full; or
• You’re a farmer or fisherman and pay your entire estimated tax by January 15 or pay your entire tax and file your tax return by March 2, 2026.

In addition, the IRS may waive the penalty if the failure was due to casualty, disaster or other unusual circumstances, and it would be inequitable to impose the penalty. The penalty can also be waived for reasonable cause during the first two years after you retire (and reach age 62) or become disabled.

OBBBA highlights

Several provisions of the OBBBA could directly affect quarterly estimated tax payments because they change how much tax some individuals will ultimately owe for the year. For example, the law introduces a temporary (2025 through 2028) additional $6,000 deduction for seniors, which can lower taxable income. It creates new deductions for overtime pay, tips and auto loan interest — available even if you don’t itemize — which can meaningfully reduce estimated liabilities. The bill also increases the state and local tax deduction cap for certain taxpayers and temporarily enhances the Child Tax Credit. Because these deductions and credits apply during the tax year rather than after, they can reduce your quarterly payment obligations mid-year, making it important to recalculate estimates to avoid overpayment or underpayment penalties.

Under current federal income tax rules, so-called personal interest expense generally can’t be deducted. One big exception is qualified residence interest or home mortgage interest, which can be deducted, subject to some limitations, if you itemize deductions on your tax return.

The One Big Beautiful Bill Act (OBBBA) adds another exception for eligible car loan interest. In tax law language, the new deduction is called qualified passenger vehicle loan interest. Are you eligible? Here are the rules.

“No tax” isn’t an accurate description

If you could deduct all your car loan interest, you’d be paying it with pre-tax dollars rather than with post-tax dollars — meaning after you paid your federal income tax bill. The new deduction has been called “no tax on car loan interest,” but that’s not really accurate. Here’s a more precise explanation.

The OBBBA allows eligible individuals — including those who don’t itemize — a temporary new deduction for some or all of the interest paid on some loans. The loans must be taken out to purchase a qualifying passenger vehicle.

Specifically, for 2025 through 2028, up to $10,000 of car loan interest can potentially be deducted each year. The loan must be taken out after 2024 and must be a first lien secured by the vehicle, which is used for personal purposes. Leased vehicles don’t qualify. So far, this may sound good, but not all buyers will qualify for the new deduction because of the limitations and restrictions summarized below.

Income-based phaseout rule

The deduction is phased out starting at $100,000 of modified adjusted gross income (MAGI) or $200,000 for married joint-filing couples. If your MAGI is above the applicable threshold, the amount that you can deduct (subject to the $10,000 limit) is reduced by $200 for each $1,000 of excess MAGI. So, for an unmarried individual, the deduction is completely phased out when MAGI reaches $150,000. For married joint filers, the deduction is completely phased out when MAGI reaches $250,000.

Qualifying vehicles

To qualify for the new deduction, the vehicle must be a car, minivan, van, SUV, pickup truck or motorcycle with a gross vehicle weight rating under 14,000 pounds. It must be manufactured primarily for use on public streets, roads and highways, and it must be new (meaning the original use begins with you). The “final assembly” of the vehicle must occur in the United States. You must report the vehicle identification number (VIN) on your tax return. Vehicles assembled in America have a special number in the VIN to signify that.

Meeting the requirements

In the law, the definition of final assembly is convoluted. The law states: “Final assembly means the process by which a manufacturer produces a vehicle at, or through the use of, a plant, factory, or other place from which the vehicle is delivered to a dealer with all component parts necessary for the mechanical operation of the vehicle included with the vehicle, whether or not the component parts are permanently installed in or on the vehicle.”

Another requirement is that your car loan lender must file an information return with the IRS that shows the amount of interest paid during the year on your qualified car loan.

Refinanced loans

If an original qualified car loan is refinanced, the new loan will be a qualified loan as long as: 1) the new loan is secured by a first lien on the eligible vehicle and 2) the initial balance of the new loan doesn’t exceed the ending balance of the original loan.

Ineligible loans

Interest on the following types of loans doesn’t qualify for the new deduction:

• Loans to finance fleet sales,
• Loans to buy a vehicle not used for personal purposes,
• Loans to buy a vehicle with a salvage title or a vehicle intended to be used for scrap or parts,
• Loans from certain related parties, and
• Any lease financing.

Conclusion

According to various reports, most American car buyers rely on loans to finance their purchases. So, the ability to deduct car loan interest is something that many taxpayers would be happy about. That said, many buyers won’t qualify for the new deduction. It’s off limits for high-income purchasers, used vehicle buyers and those who buy foreign imports. Contact us with any questions.

The newly enacted One, Big, Beautiful Bill Act (OBBBA) represents a major move by President Trump and congressional Republicans to roll back a number of clean energy tax incentives originally introduced or expanded under the Inflation Reduction Act (IRA). Below is a summary of the key individual tax credits that will soon be scaled back or eliminated.

Clean vehicle tax credits

If you’re planning to buy a clean vehicle, consider acting soon to take advantage of expiring tax benefits:

New clean vehicle credit. This credit offers up to $7,500 for qualifying new electric and fuel cell vehicles, depending on how the battery components and critical minerals are sourced. Vehicles that meet only one of the sourcing criteria may be eligible for a reduced $3,750 credit. Originally set to expire in 2032, this credit now ends on September 30, 2025.

The maximum manufacturer’s suggested retail price is $55,000 for cars and $80,000 for SUVs, trucks and vans. To qualify, your adjusted gross income (AGI) must not exceed $150,000 ($300,000 for married couples filing jointly and $225,000 for heads of households).

Used clean vehicle credit. Buyers of eligible used EVs or fuel cell vehicles may claim up to $4,000, or 30% of the purchase price — whichever is lower — if bought from a dealer. This credit also expires on September 30, 2025.

The maximum price of the vehicle is $25,000. To be eligible for the credit, your AGI must not exceed $75,000 for single taxpayers ($150,000 for married joint filers and $112,500 for heads of households).

Alternative fuel refueling property credit

Homeowners who install equipment to recharge EVs or dispense clean fuel may qualify for the alternative fuel vehicle refueling property credit. The IRA had extended and expanded this benefit.

For property placed in service at a primary residence after 2023, the credit equals 30% of the installation cost, up to $1,000 per item (charging port, fuel dispenser, or storage property). Equipment must be placed in service by June 30, 2026, instead of the previous end-of-2032 deadline.

Home energy tax credits

The OBBBA shortens the lifespan of several tax credits available to individual homeowners. Those planning home upgrades may want to act swiftly to make the most of these two opportunities.

Energy efficient home improvement credit. This tax break provides a 30% nonrefundable credit for qualified expenses such as energy-efficient doors, windows, skylights, insulation, heat pumps and home energy audits. The maximum credit you can claim this year is $1,200

There are no income restrictions, but credit caps vary by item. In 2025, credit limits include:

• $250 per exterior door ($500 total),
• $600 for windows, central A/C, panels, and select equipment,
• $150 for energy audits, and
• $2,000 for heat pumps, water heaters, and biomass systems (superseding the usual $1,200 limit).

This credit was previously scheduled to end after 2032. The expiration has been moved up to December 31, 2025.

Residential clean energy credit. This tax break provides a 30% nonrefundable credit for renewable energy systems like solar, wind, geothermal, and biomass installations. There are no income limits. Under prior law, this credit was set to expire after 2034. The OBBBA makes the new expiration date December 31, 2025.

Secure savings now

Given the shortened timelines and reduced availability of clean energy tax benefits under the OBBBA, proactive planning is key. If you’re interested, you should make the most of these incentives while they last. Contact us with any questions about your situation.

The One Big Beautiful Bill Act (OBBBA) includes a number of beneficial changes that will help small business taxpayers. Perhaps the biggest and best changes are liberalized rules for depreciating business assets. Here’s what you need to know.

100% bonus depreciation is back

The new law permanently restores 100% first-year depreciation for eligible assets acquired and placed in service after January 19, 2025. The last time 100% bonus depreciation was allowed for eligible assets was in 2022. The deduction percentage was generally reduced to 80% for 2023, 60% for 2024, and 40% for eligible assets placed in service between January 1, 2025, and January 19, 2025.

For certain assets with longer production periods, these percentage cutbacks were delayed by one year. For example, a 60% first-year bonus depreciation rate applies to long-production-period property placed in service between January 1, 2025, and January 19, 2025.

Eligible assets include most depreciable personal property such as equipment, computer hardware and peripherals, commercially available software and certain vehicles. First-year bonus depreciation can also be claimed for real estate qualified improvement property (QIP). This is defined as an improvement to an interior portion of a non-residential building placed in service after the building was initially put into use. However, expenditures attributable to the enlargement of a building, elevators or escalators, or the internal structural framework of a building don’t count as QIP. They usually must be depreciated over 39 years.

Section 179 first-year depreciation

For eligible assets placed in service in tax years beginning in 2025, the OBBBA increases the maximum amount that can immediately be written off via first-year depreciation (sometimes called expensing) to $2.5 million. This is up from $1.25 million for 2025 before the new law.

A phase-out rule reduces the maximum Sec. 179 deduction if, during the year, you place in service eligible assets in excess of $4 million. This is up from $3.13 million for 2025 before OBBBA was enacted. These increased OBBBA amounts will be adjusted annually for inflation for tax years beginning in 2026.

Eligible assets include the same items that are eligible for bonus depreciation. Sec. 179 deductions can also be claimed for real estate QIP (defined earlier), up to the maximum annual allowance. In addition, Sec. 179 deductions are also allowed for roofs, HVAC equipment, fire protection and alarm systems, and security systems for non-residential real property. Finally, Sec. 179 write-offs can be claimed for depreciable personal property used predominantly in connection with furnishing lodging.

There’s a special limit on Sec. 179 deductions for heavy SUVs used over 50% for business. This means vehicles with gross vehicle weight ratings between 6,001 and 14,000 pounds. For tax years beginning in 2025, the maximum Sec. 179 deduction for a heavy SUV is $31,300.

Strategy: Sec. 179 deductions are subject to a number of limitations that don’t apply to first-year bonus depreciation. In particular, things can get complicated if you operate your business as a partnership, LLC treated as a partnership for tax purposes or an S corporation. The conventional wisdom is to claim 100% first-year bonus depreciation to the extent allowed rather than claiming Sec. 179 deductions for the same assets.

First-year depreciation for qualified production property

The OBBBA allows additional 100% first-year depreciation for qualified production property (QPP) in the year it’s placed in service. QPP is non-residential real estate, such as a building, that’s used as an integral part of a qualified production activity, such as the manufacturing, production, or refining of tangible personal property. Before the new law, non-residential buildings generally had to be depreciated over 39 years.

QPP doesn’t include any part of non-residential real property that’s used for offices, administrative services, lodging, parking, sales or research activities, software development, engineering activities and other functions unrelated to the manufacturing, production or refining of tangible personal property.

The favorable new 100% first-year depreciation deal is available for QPP when the construction begins after January 19, 2025, and before 2029. The property must be placed in service in the U.S. or a U.S. possession before 2031.
