IRS Sets Standard Mileage Rate for 2026 at 72.5 Cents - Eide Bailly 

The IRS has released (2026-10) the 2026 standard mileage rates. The rates are used to determine the deductible costs of using a vehicle for business, charitable, medical, or moving purposes. The new rates are effective January 1, 2026.

 

IRS Increases 2026 Business Mileage Rate, Cuts Medical And Moving Rates - Kelly Phillips Erb, Forbes:

If you’re wondering about the differences in rates for business and medical purposes, or for moving, there is a reason. The standard mileage rate for business is calculated using an annual study of the fixed and variable costs of operating an automobile, including depreciation, insurance, repairs, tires, maintenance, gas, and oil. In contrast, the rate for medical and moving purposes is based just on the variable costs.

 

2025 Greatest Tax Policy Hits

Top Federal Tax Policies Of 2025 - Asha Glover, Law360 Tax Authority ($):

The budget reconciliation bill is the biggest tax policy passed this year, and its permanence helps foster certainty for businesses, making it easier for them to take the kinds of risks that create jobs and innovation, Arnold & Porter Kaye Scholer LLP partner Mark Epley said.

....

Among the bill's many tax changes, it allows projects to receive full energy tax credit values under current Inflation Reduction Act rules through Dec. 31, 2027. It also extends and boosts the state and local tax deduction cap to $40,000 with annual increases until 2030, when it will return to the current $10,000 cap. It retains the current ability for all pass-through entities to claim the SALT deduction at the entity level, which would have been barred under the House of Representative's version of the bill.

The other top policy items listed were the lapse of ACA enhanced tax credits, the talk of a "revenge tax" that would address allegedly unfair foreign trade practices; IRS and Treasury tax staffing; and IRS guidance on OBBBA.

 

Looking to 2026: Home Gains and Expiring Energy Credits

Two Bills, and Maybe Trump, Favor Raising Tax Cap on Home Sales - Doug Sword, Tax Notes ($):

Attempts to lift the capital gains exclusion on the sale of principal homes may be getting some traction after nearly 30 years.

Even if the political atmosphere is too tense to support a bipartisan tax bill in an election year, there are still must-pass vehicles that could carry a tax title, and House Ways and Means Committee member Jimmy Panetta, D-Calif., is eyeing them for his effort to double the capital gains exclusion on home sales.

...

The $250,000 cap for single homeowners and $500,000 for married ones has been around since 1997 — unadjusted for inflation — and there have been bills to change that since 2005.

 

More Clean Energy Credits Are Set to Expire in 2026 Under OBBBA - Katie Lobosco, Tax Notes ($):

Three clean energy tax credits will expire at the end of June 2026.

The section 45L new energy-efficient homes tax credit will terminate for property acquired after June 30, 2026. It’s available to eligible contractors that build or substantially reconstruct energy-efficient single- or multifamily homes and is worth up to $5,000 per home. The credit was originally scheduled to expire at the end of 2032.

The section 179D energy-efficient commercial buildings tax deduction will end for property that has not begun construction by June 30, 2026. Since the IRA, the amount of the deduction has been equal to the lesser of the cost of the installed property or the maximum savings per square foot, indexed annually for inflation. The IRA had made the deduction permanent.

The section 30C alternative fuel vehicle refueling property tax credit is scheduled to expire for property placed in service after June 30, 2026. The credit is available to businesses or individuals that install alternative fueling equipment in qualifying low-income, nonurban communities and is worth up to 30 percent of the cost.

What if Tariffs are Struck Down?

Donald Trump expected to impose new levies if Supreme Court strikes down tariffs - Aime Williams, Financial Times:

The Supreme Court is poised to rule as soon as January on the legality of the president’s use of emergency powers to hammer trading partners with tariffs, leaving the centrepiece of his economic policy hanging in the balance.

Markets traders are braced for turmoil if the US’s top court rules against Trump, potentially leaving the federal government on the hook for billions of dollars in repayments of levies that have already been collected.

But diplomats and trade lawyers believe the administration has a series of plans in place to shore up the levies regardless of the court’s ruling, using a combination of existing trade measures alongside alternative laws.

 

Hawaii Tax Cruises

Hawaii Cruise Ship Tax Survives, but Its Voyage Will Be Stormy - Tom Yamachika, Bloomberg ($):

US District Court Judge Jill A. Otake cleared Hawaii’s implementation of a new tourist tax on cruise ship passengers in a ruling last week in Cruise Lines International Association Inc. v. Suganuma . This new tax, aimed at tackling climate change, will take effect Jan. 1.

...

For now, the tax remains standing and will take effect as planned. But the devil’s in the details—and those may yet sink the tax as the industry and the government continue their assaults. Meanwhile, one wonders why so much public money is being spent on marketing Hawaii as a tourist haven if the state government is more focused on milking the tourists like cattle.

 

Taxing Data Centers

Data Centers Are Heavily Taxed. How Much is Too Much? = Jared Walczak, The SALT Road. "Texas does quite well, with 429 data centers. But states that really punch above their weight (in addition to Virginia) include Oregon, Iowa, Montana, Nevada, North Dakota, Arizona, Wyoming, and Ohio. Each state has its own advantages."

 

The Problem With Postmarks

U.S. Postal Service Postmark Rules’ Implications for Tax Filings - Leslie Book, Tax Notes ($):

Last summer, the U.S. Postal Service issued a notice of proposed rulemaking addressing postmarks. 90 F.R. 38716 (Aug. 11, 2025). The U.S. Postal Service finalized the rules on November 24, 2025. As the preamble to the final rule discusses, the postal service sought to define the term postmark and explain the its operational use of the postmark.

One key point that the preamble discusses is that the postmark date does not necessarily align with the date that someone drops off a properly addressed envelope at the post office. 

...

Most prudent advisers will likely mail important documents to the IRS using certified mail with a return receipt or via an authorized private delivery service. Despite the best practice of using certified mail or other forms of mailing that provide documentary proof that an item has been mailed, most documents filed with the IRS are sent via traditional first-class mail, and that is why these new U.S. Postal Service rules are so important.

Ways to spend your FSA money so you don’t lose it - Kay Bell, Don't Mess With Taxes. "Any deductible or added costs for that tooth cleaning you put off until the last minute qualifies for FSA coverage. So do the prescription pain meds your dentist gives you if your procedure is more major, and ache inducing."

The Value of Friendly Advice

Don't Let Friends Take Tax Advice From Friends! - Manasa Nadig, The Buzz About Taxes:

The Horowitz’s had been chatting with other expatriates about whether they owed US taxes on foreign income. They’d heard from friends that income earned in Saudi Arabia was only taxable in Saudi Arabia. Peter thought he didn’t have FBAR filing requirements. Susan didn’t even know what an FBAR was.

Sound familiar? This is the moment the bridge question becomes relevant.

The court’s response was sharp. The judges basically said: Your friends’ opinions don’t override what Schedule B explicitly asks you to do. And here’s the kicker—the fact that the Horowitz’s were even having these conversations meant they were aware of their compliance obligations. They just chose to have those conversations with friends instead of with tax professionals.

The article explains how that turned out to be costly for the taxpayers. No matter how convincing and confident your friends at the airport or golf course are about their tax tips, run them by your tax pro first.
