The new rules are complicated. Here’s how to make sense of them if you’re shopping for an electric vehicle.

The Department of Treasury published new rules last year that will determine which new electric vehicles, purchased for personal use, will qualify for a $7,500 tax credit. They went into effect on April 18, 2023, and last for the next decade or so.
These new tax credit rules are complicated. The list of cars that qualify for the new tax credit can change from year to year — and even month to month. Many buyers in the EV market might have a few questions, including: Should I buy that new car now, or should I wait? Which cars qualify for the current tax credit, and which ones will earn the new one?
This is Heatmap’s guide to the new tax credit, why it matters, and what to keep in mind as you go EV shopping.
If you’re an ordinary American buying a brand-new EV to run errands and pick up the kids, these new rules apply to you. They will determine which cars you can get a federally funded discount on.
If you’re not buying a new car for personal use — because you’re getting it for your business, say, or because you’re buying a used EV — these new rules don’t apply to you. But you may qualify for other new subsidies. We get into those below.
And even if you are in that first category, you may discover it’s much cheaper to lease a new EV instead of buying it outright. We get into why below, too.
They completely change how the United States approaches the EV industry.
During the Bush and Obama administrations, the U.S. was focused mostly on getting automakers to begin to experiment with EVs. So it discounted the first 200,000 or so electric vehicles that each manufacturer sold by up to $7,500. If a company had cumulatively sold more than that number over time, as Tesla and General Motors eventually did, then the discount expired. By 2022, that had led to a peculiar situation where foreign automakers, such as Hyundai, could use the subsidy, while some of the largest American automakers couldn’t.
Now, U.S. policy is focused on two goals: (1) building up a domestic supply chain for EVs and (2) getting more EVs on the road. So the tax break is completely uncapped — any automaker can use it as many times as possible if they meet the criteria.
But many new requirements apply: Only cars that undergo final assembly in North America will qualify for any of the tax credit. Then, cars with a battery that was more than 50% made in North America will qualify for a $3,750 subsidy. And cars where at least 40% of the “critical minerals” used come from the U.S. or a country with whom we have a free-trade agreement will qualify for another $3,750 subsidy.
Those percentage-based requirements will ramp up over time. By 2029, for instance, 100% of a car’s battery and battery components must be made in North America.
Because Congress said so. The Inflation Reduction Act, which Democratic majorities in the House and Senate passed last year, mandated this change to the EV tax credit as part of its broad expansion of American climate policy.
Initially, fewer EVs will receive a subsidy under the new rules, Biden officials say. On a press call with reporters, a senior Treasury official argued that more cars will eventually qualify under the new rules than qualified under the old ones.
This year, at least 15 car or light trucks will receive some or all of the credit. Only some of those vehicles will qualify for the full $7,500 tax credit; some will qualify for a partial $3,750 tax credit. Here is the full list of qualifying models, along with the amount of the tax credit that they will earn:
• Audi Q5 TFSI e Quattro PHEV ($3,750)
• Cadillac LYRIQ ($7,500)
• Chevrolet Bolt ($7,500)
• Chevrolet Bolt EUV ($7,500)
• Chrysler Pacifica PHEV ($7,500)
• Ford Escape Plug-in Hybrid ($3,750)
• Ford F-150 Lightning, Standard & Extended Range ($7,500)
• Jeep Wrangler PHEV 4xe ($3,750)
• Jeep Grand Cherokee PHEV 4xe ($3,750)
• Lincoln Corsair Grand Touring ($3,750)
• Rivian R1S, Dual Large & Quad Large ($3,750)
• Rivian R1T, Dual Large, Dual Max, & Quad Large ($3,750)
• Tesla Model X Long Range ($7,500)
• Tesla Model 3 Performance ($7,500)
• Tesla Model 3 Long Range AWD ($3,500)
• Tesla Model Y AWD, Rear-Wheel Drive, & Performance ($7,500)
• Volkswagen ID.4 AWD PRO, PRO, S, & Standard ($7,500)
Some vehicles that earned the full tax credit in 2023, such as the Ford Mustang Mach E, don’t qualify for any benefit as of January 2, 2024.
Yes. A few examples: The Hummer EV, which costs more than $110,000 a piece, won’t qualify for either the new or old tax credit — it’s too expensive. And the Polestar 2 won’t qualify because it’s assembled in China.
Yes. Starting this year, the U.S. is preventing cars that receive too much manufacturing input from a “foreign entity of concern” — that is, China — from qualifying for any of the tax credit. This has reduced the number of vehicles that qualify for the $7,500 bonus.
This year, the government will also allow buyers to refund their EV tax credit at the dealership. That means buyers can now get up to a $7,500 discount at the moment when they buy their car instead of waiting until they file their taxes in the following year.
Yes. A married couple must have an adjusted gross income of less than $300,000 a year, and a single filer must have an AGI of less than $150,000 a year, to qualify for any aspect of the subsidy. A head-of-household must have an income of less than $225,000 a year.
Yes. Under the proposed rule, cars must have an MSRP below $55,000 to qualify for the credit. Vans, pickup trucks, and SUVs must have an MSRP below $80,000.
Yes. The Inflation Reduction Act also included a new $7,500 tax credit for EVs used for any commercial purpose. The Treasury Department is expected to interpret that provision to cover leasing, but it hasn’t announced the guidelines for that rule yet, so we don’t know for sure.
But the provision will probably tilt new EV drivers toward leasing their car rather than buying it outright, because the dealer should — emphasis on should — offer relative discounts on leasing vehicles as compared to buying them.
Yes. There’s also a new $4,000 tax credit for buying a used EV that costs $25,000 or less. It went into effect on January 1, 2023, so you can go ahead and use it today.
But note that it has even stricter income limits: Married couples can only take advantage of it if they make $150,000 or less, and other filers if they make $75,000 or less.
Here’s the list of cars that qualified for the $7,500 tax credit before April 18, 2023, according to the Department of Energy.
• Audi Q5 TFSI e Quattro (PHEV)
• BMW 330e *
• BMW X5 xDrive45e**

The Trump administration has started to weaken the rules requiring cars and trucks to get more fuel-efficient every year,
In a press event on Wednesday in the Oval Office, flanked by advisors and some of the country’s top auto executives, President Trump declared that the old rules “forced automakers to build cars using expensive technologies that drove up costs, drove up prices, and made the car much worse.”
He said that the rules were part of the “green new scam” and that ditching them would save consumers some $1,000 every year. That framed the rollback as part of the president’s seeming pivot to affordability, which has happened since Democrats trounced Republicans in the November off-cycle elections.
That pivot remains belated and at least a little half-hearted: On Wednesday, Trump made no mention of dropping the auto tariffs that are raising imported car prices by perhaps $5,000 per vehicle, according to Cox Automotive. Ditching the fuel economy rules, too, could increase demand for gasoline and thus raise prices at the pump — although they remain fairly low right now, with the national average below $3 a gallon.
What’s more interesting — and worrying — is that the rules fit into the administration’s broader war on innovation in the American car and light-duty truck sector. The United States essentially has two ways to regulate pollution from cars and light trucks: It can limit greenhouse gas emissions from new cars and trucks, and it can require the fuel economy from new vehicles to get a little better every year.
Trump is pulling screws and wires out of both of these systems. In the first category, he’s begun to unwind the Environmental Protection Agency’s limits on carbon pollution from cars and light duty trucks, which he termed an “EV mandate.” (The Biden-era rules sought to require about half of new car sales be electric by 2030, although hybrids could help meet that standard.) Trump is also trying to keep the EPA from ever regulating anything to do with carbon pollution again by going after the agency’s “Endangerment Finding” — a scientific assessment that greenhouse gases are dangerous to human wellbeing.
That’s only half of the president’s war on air pollution rules, though. Since the oil crises of the 1970s, the National Highway Traffic Safety Administration has regulated fuel economy for new vehicles under the Corporate Average Fuel Economy, or CAFE, standards. When these rules are binding, the agency can require new cars and trucks sold in the U.S. to get a little more fuel-efficient every year. The idea is that these rules help limit the country’s gasoline consumption, thus keeping a lid on oil prices and letting the whole economy run more efficiently.
President Trump’s signature tax law, the One Big Beautiful Bill Act, already eliminated the fines that automakers have to pay when they fail to meet the standard. That change, pushed by Senator Ted Cruz of Texas, effectively rendered the regulation toothless. But now Trump is weakening the rules just for good measure. (At the press conference on Wednesday, Cruz stood behind the president — and next to Jim Farley, the CEO of Ford.)
Under the new Trump proposal, automakers would need to achieve only an average of 34.5 miles per gallon in 2031. Under Biden’s proposal, they needed to hit 50 miles per gallon that year.
Those numbers, I should add, are somewhat deceptive — because of how CAFE standards are calculated, the headline number is 20% to 30% stricter than a real-world fuel economy number. In essence, that means the new Trump era rules will come out to a real-world mile-per-gallon number in the mid-to-high 20s. That will give automakers ample regulatory room to sell more inefficient and gas-guzzling sport utility vehicles and pickups, which remain more profitable than electric vehicles.
Which is not ideal for air pollution or the energy transition. But the real risk for the American automaking industry is not that Ford might churn out a few extra Escapes over the next several years. It’s that the Trump proposal would eliminate the ability for automakers to trade compliance credits to meet the rules. These credit markets — which allow manufacturers of gas guzzlers to redeem themselves by buying credits generated by cleaner cars — have been a valuable revenue source for new vehicle companies like Tesla, Lucid, and Rivian. The Trump proposal would cut off that revenue — and with it, one of the few remaining ways that automakers are cross-subsidizing EV innovation in the United States.
During his campaign, President Trump said that he wanted the “cleanest air.” That promise is looking as incorrect as his pledge to cut electricity costs in half within a year.
How will America’s largest grid deal with the influx of electricity demand? It has until the end of the year to figure things out.
As America’s largest electricity market was deliberating over how to reform the interconnection of data centers, its independent market monitor threw a regulatory grenade into the mix. Just before the Thanksgiving holiday, the monitor filed a complaint with federal regulators saying that PJM Interconnection, which spans from Washington, D.C. to Ohio, should simply stop connecting new large data centers that it doesn’t have the capacity to serve reliably.
The complaint is just the latest development in a months-long debate involving the electricity market, power producers, utilities, elected officials, environmental activists, and consumer advocates over how to connect the deluge data centers in PJM’s 13-state territory without further increasing consumer electricity prices.
The system has been pushed into crisis by skyrocketing capacity auction prices, in which generators get paid to ensure they’re available when demand spikes. Those capacity auction prices have been fueled by high-octane demand projections, with PJM’s summer peak forecasted to jump from 154 gigawatts to 210 gigawatts in a decade. The 2034-35 forecast jumped 17% in just a year.
Over the past two two capacity auctions, actual and forecast data center growth has been responsible for over $16.6 billion in new costs, according to PJM’s independent market monitor; by contrast, the previous year’s auction generated a mere $2.2 billion. This has translated directly to higher retail electricity prices, including 20% increases in some parts of PJM’s territory, like New Jersey. It has also generated concerns about reliability of the whole system.
PJM wants to reform how data centers interconnect before the next capacity auction in June, but its members committee was unable to come to an agreement on a recommendation to PJM’s board during a November meeting. There were a dozen proposals, including one from the monitor; like all the others, it failed to garner the necessary two-thirds majority vote to be adopted formally.
So the monitor took its ideas straight to the top.
The market monitor’s complaint to the Federal Energy Regulatory Commission tracks closely with its plan at the November meeting. “PJM is currently proposing to allow the interconnection of large new data center loads that it cannot serve reliably and that will require load curtailments (black outs) of the data centers or of other customers at times. That result is not consistent with the basic responsibility of PJM to maintain a reliable grid and is therefore not just and reasonable,” the filing said. “Interconnecting large new data center loads when adequate capacity is not available is not providing reliable service.”
A PJM spokesperson told me, “We are still reviewing the complaint and will reserve comment at this time.”
But can its board still get a plan to FERC and avoid another blowout capacity auction?
“PJM is going to make a filing in December, no matter what. They have to get these rules in place to get to that next capacity auction in June,” Jon Gordon, policy director at Advanced Energy United, told me. “That’s what this has been about from the get-go. Nothing is going to stop PJM from filling something.”
The PJM spokesperson confirmed to me that “the board intends to act on large load additions to the system and is expected to provide an indication of its next steps over the next few weeks.” But especially after the membership’s failure to make a unified recommendation, what that proposal will be remains unclear. That has been a source of agita for the organizations’ many stakeholders.
“The absence of an affirmative advisory recommendation from the Members Committee creates uncertainty as to what reforms PJM’s Board of Managers may submit to the Federal Energy Regulatory Commission (FERC), and when stakeholders can expect that submission,” analysts at ClearView Energy Partners wrote in a note to clients. In spite of PJM’s commitments, they warned that the process could “slip into January,” which would give FERC just enough time to process the submission before the next capacity auction.
One idea did attract a majority vote from PJM’s membership: Southern Maryland Electric Cooperative’s, which largely echoed the PJM board’s own plan with some amendments. That suggestion called for a “Price Responsive Demand” system, in which electricity customers would agree to reduce their usage when wholesale prices spike. The system would be voluntary, unlike an earlier PJM proposal, which foresaw forcing large customers to curtail their power. “The load elects to not take on a capacity obligation, therefore does not pay for capacity, and is required to reduce demand during stressed system conditions,” PJM explained in an update. The Southern Maryland plan tweaks the PRD system to adjust its pricing mechanism. but largely aligns with what PJM’s staff put forward.
“There’s almost no real difference between the PJM proposal and that Southern Maryland proposal,” Gordon told me.
That might please restive stakeholders, or at least be something PJM’s board could go forward with knowing that the balance of its voting membership agreed with something similar.
“We maintain our view that a final proposal could resemble the proposed solution package from PJM staff,” the ClearView note said. “We also think the Board could propose reforms to PJM’s PRD program. Indeed, as noted above, SMECO’s revisions to the service gained majority support.”
The PJM plan also included relatively uncontroversial reforms to load forecasting to cut down on duplicated requests and better share information, and an “expedited interconnection track” on which new, large-scale generation could be fast-tracked if it were signed off on by a state government “to expedite consideration of permitting and siting.”
Gordon said that the market monitor’s complaint could be read as the organization “desperately trying to get FERC to weigh in” on its side, even if PJM is more likely to go with something like its own staff-authored submission.
“The key aspect of the market monitor’s proposal was that PJM should not allow a data center to interconnect until there was enough generation to supply them,” Gordon explained. During the meeting preceding the vote, “PJM said they didn’t think they had the authority to deny someone interconnection.”
This dispute over whether the electricity system has an obligation to serve all customers has been the existential question making the debate about how to serve data centers extra angsty.
But PJM looks to be trying to sidestep that big question and nibble around the edges of reform.
“Everybody is really conflicted here,” Gordon told me. “They’re all about protecting consumers. They don’t want to see any more increases, obviously, and they want to keep the lights on. Of course, they also want data center developers in their states. It’s really hard to have all three.”
Atomic Canyon is set to announce the deal with the International Atomic Energy Agency.
Two years ago, Trey Lauderdale asked not what nuclear power could do for artificial intelligence, but what artificial intelligence could do for nuclear power.
The value of atomic power stations to provide the constant, zero-carbon electricity many data centers demand was well understood. What large language models could do to make building and operating reactors easier was less obvious. His startup, Atomic Canyon, made a first attempt at answering that by creating a program that could make the mountains of paper documents at the Diablo Canyon nuclear plant, California’s only remaining station, searchable. But Lauderdale was thinking bigger.
In September, Atomic Canyon inked a deal with the Idaho National Laboratory to start devising industry standards to test the capacity of AI software for nuclear projects, in much the same way each update to ChatGPT or Perplexity is benchmarked by the program’s ability to complete bar exams or medical tests. Now, the company’s effort is going global.
On Wednesday, Atomic Canyon is set to announce a partnership with the United Nations International Atomic Energy Agency to begin cataloging the United Nations nuclear watchdog’s data and laying the groundwork for global standards of how AI software can be used in the industry.
“We’re going to start building proof of concepts and models together, and we’re going to build a framework of what the opportunities and use cases are for AI,” Lauderdale, Atomic Canyon’s chief executive, told me on a call from his hotel room in Vienna, Austria, where the IAEA is headquartered.
The memorandum of understanding between the company and the UN agency is at an early stage, so it’s as yet unclear what international standards or guidelines could look like.
In the U.S., Atomic Canyon began making inroads earlier this year with a project backed by the Institute of Nuclear Power Operators, the Nuclear Energy Institute, and the Electric Power Research Institute to create a virtual assistant for nuclear workers.
Atomic Canyon isn’t the only company applying AI to nuclear power. Last month, nuclear giant Westinghouse unveiled new software it’s designing with Google to calculate ways to bring down the cost of key components in reactors by millions of dollars. The Nuclear Company, a startup developer that’s aiming to build fleets of reactors based on existing designs, announced a deal with the software behemoth Palantir to craft the software equivalent of what the companies described as an “Iron Man suit,” able to swiftly pull up regulatory and blueprint details for the engineers tasked with building new atomic power stations.
Lauderdale doesn’t see that as competition.
“All of that, I view as complementary,” he said.
“There is so much wood to chop in the nuclear power space, the amount of work from an administrative perspective regarding every inch of the nuclear supply chain, from how we design reactors to how we license reactors, how we regulate to how we do environmental reviews, how we construct them to how we maintain,” he added. “Every aspect of the nuclear power life cycle is going to be transformed. There’s no way one company alone could come in and say, we have a magical approach. We’re going to need multiple players.”
That Atomic Canyon is making inroads at the IAEA has the potential to significantly broaden the company’s reach. Unlike other energy sources, nuclear power is uniquely subject to international oversight as part of global efforts to prevent civilian atomic energy from bleeding over into weapons production.
The IAEA’s bylaws award particular agenda-setting powers to whatever country has the largest fleet of nuclear reactors. In the nearly seven decades since the agency’s founding, that nation has been the U.S. As such, the 30 other countries with nuclear power have largely aligned their regulations and approaches to the ones standardized in Washington. When the U.S. artificially capped the enrichment levels of traditional reactor fuel at 5%, for example, the rest of the world followed.
That could soon change, however, as China’s breakneck deployment of new reactors looks poised to vault the country ahead of the U.S. sometime in the next decade. It wouldn’t just be a symbolic milestone. China’s emergence as the world’s preeminent nuclear-powered nation would likely come with Beijing’s increased influence over other countries’ atomic energy programs. As it is, China is preparing to start exporting its reactors overseas.
The role electricity demand from the data centers powering the AI boom has played in spurring calls for new reactors is undeniable. But if AI turns out to have as big an impact on nuclear operations as Lauderdale predicts, an American company helping to establish the global guidelines could help cement U.S. influence over a potentially major new factor in how the industry works for years, if not decades to come.
