A new amendment to Arizona’s laws, A.R.S. Title 12, is about to change the game for personal injury claims in Phoenix, especially for catastrophic injury cases. Starting January 1, 2026, the way we calculate and argue future loss of income is getting a major overhaul. While the legislature claims it’s about standardization, for plaintiffs, it really just means new and complicated hurdles to getting full compensation.
Key Takeaways
- Arizona House Bill 3125 goes into effect on January 1, 2026, and it forces a specific actuarial method for calculating future lost earnings in catastrophic injury cases.
- Plaintiffs now have to use expert testimony from a licensed actuary or a forensic economist who follows the new A.R.S. Section 12-705 rules.
- The law puts a 2.5% cap on the annual growth rate for future income projections, a cap that can only be exceeded with “clear and convincing evidence.”
- Defense attorneys can now bring in evidence about potential future economic shifts, like automation in the plaintiff’s industry or pre-injury job instability, to attack income projections.
- Anyone who has suffered a catastrophic injury in Phoenix needs to talk to a lawyer right away to figure out how these new rules will impact their ability to recover lost wages.
Arizona House Bill 3125: Redefining Lost Earning Capacity
On July 1, 2025, Governor Katie Hobbs signed House Bill 3125, and it’s now officially on the books as A.R.S. Section 12-705. This new law which kicks in January 1, 2026, completely upends how we calculate future economic damages, specifically lost earning capacity in personal injury actions. It’s a big move away from the old common law approach that gave experts a lot more leeway in their projections.
Before this, a qualified economist could use various methods to project a plaintiff’s lost future earnings. This predictably led to a battle of the experts where plaintiff and defense numbers were miles apart, which often confused juries. While the new statute supposedly creates a more structured framework, many practitioners argue it’s a tool that could inadvertently shortchange plaintiffs. The legislature’s stated goal of promoting “consistency and predictability” sounds good on paper, but in practice, it might just mean consistently lower recoveries.

The biggest change in A.R.S. Section 12-705 is the new mandate for “generally accepted actuarial principles and methods” when projecting future lost earnings. This isn’t just semantics. It means the plaintiff’s expert has to be a licensed actuary or a forensic economist who can prove their work fits those strict standards. Gone are the days when a general economist could just extrapolate from past pay stubs. It’s a much higher bar, requiring a very specific type of expert that not all economic consultants are qualified to be.
Second, the statute hits plaintiffs with a hard cap on the annual growth rate used for projecting their pre-injury income trajectory. The rate is now pegged at 2.5% per year unless a plaintiff can show “clear and convincing evidence” for a higher one. This is a huge deal, particularly for people in professions with high wage growth or for younger workers. For example, a software engineer in Scottsdale, whose salary might have reasonably grown by 5-7% annually, will now have their projected growth automatically slashed to 2.5% unless their legal team can meet that “clear and convincing” standard, an incredibly high burden of proof in any Arizona court.
Third, the new law explicitly gives the defense a green light to bring in evidence about the plaintiff’s pre-injury work history, industry trends, and even broad economic forecasts that could knock down future earnings. The statute solidifies the admissibility of this kind of evidence, which basically invites a more aggressive defense strategy on lost income. This means they can argue that automation was going to eliminate the plaintiff’s job anyway or point to past periods of unemployment, forcing the plaintiff to defend their entire career path against hypothetical future problems.
Who is Affected: Catastrophic Injury Victims in Arizona
This law is going to hit people who have suffered a catastrophic injury in Arizona the hardest, especially those in the Phoenix metro area who have had their earning capacity wiped out. We’re talking about injuries that cause a permanent or significant loss of ability to work. Think of spinal cord injuries, severe traumatic brain injuries, or amputations that make it impossible for someone to return to their old job, if they can work at all.
Take a construction worker who falls from a downtown Phoenix high-rise and suffers a permanent back injury. Their legal team now has to fight through these new, stricter evidentiary rules. Their expert must be an actuary, and the wage growth for their construction career is stuck at that 2.5% cap unless they can prove, with near certainty, that their career would have grown much faster. The practical impact is devastating for a young worker who had decades of potential raises ahead of them, as they now stand to lose a substantial portion of their projected lifetime income because of this cap.
It’s also a nightmare for the self-employed or anyone with an irregular income stream. Documenting pre-injury earning capacity becomes intensely difficult under this new framework. Frankly, the statute seems to favor salaried employees with perfect W-2 histories and stable wage growth, putting those in more volatile or entrepreneurial professions at a clear disadvantage. I’ve heard the same observation from colleagues across the state.

Concrete Steps for Plaintiffs and Legal Counsel
For anyone with a catastrophic injury claim in Phoenix, A.R.S. Section 12-705 means being proactive is the only way to protect a claim for loss of income. Here’s what that looks like in practice.
Immediate Legal Consultation
First, it’s time to hire a personal injury attorney in Phoenix who specializes in catastrophic injury cases. This isn’t a job for a generalist. A specialist will already know the ins and outs of A.R.S. Section 12-705 and will have a network of qualified forensic actuaries ready to go. Trying to handle this alone is a recipe for disaster. For example, a simple mistake in selecting an expert could get the entire economic damages claim thrown out by a judge. The Arizona State Bar Association’s official website is a good starting point for finding qualified lawyers.
Complete Documentation of Pre-Injury Earnings
Every scrap of financial paper related to pre-injury income is now gold. We’re talking at least five years of tax returns (W-2s and 1099s), pay stubs, employment contracts, and even old performance reviews and promotion letters. Anything that documents bonuses, commissions, or other benefits is vital. For a self-employed person, this means clean profit and loss statements, invoices, and business tax filings. The new statute is built around verifiable data, so a strong, consistent paper trail is the foundation of the entire earning capacity claim.
Retaining a Qualified Actuarial Expert
The legal team has to bring in a licensed actuary or a forensic economist who lives and breathes these actuarial principles. This expert will be the one to write the future lost earnings report that can survive in court under A.R.S. Section 12-705. Using the plaintiff’s documented income, they’ll apply the appropriate discount rates and stick to that 2.5% growth cap, unless there’s a powerful argument for more. A good expert knows how to build a report that satisfies the law while still being persuasive to a jury, and you can bet the defense team will pick apart their methodology line by line.
Building the “Clear and Convincing Evidence” Case
If the injured person worked in a field where wage growth was realistically higher than 2.5% annually, the legal team has a real fight on its hands to build that “clear and convincing evidence” case. This means digging up industry-specific wage reports from the Bureau of Labor Statistics (the BLS data for Arizona is key here), getting testimony from vocational rehabilitation specialists, or even bringing in former employers. This is pure strategic litigation, and it requires a deep understanding of the law and the economic realities of a specific profession. The evidence must demonstrate that this specific person, given their skills and career path, was on a trajectory for higher earnings. It’s a very high bar, and it requires careful preparation to overcome the statute’s 2.5% presumption.
Addressing Defense Arguments Proactively
Since the defense can now throw everything at the wall to see what sticks, automation, economic downturns, you name it, the plaintiff’s team has to be ready. This means having vocational experts ready to testify about the plaintiff’s pre-injury job security or an economist to rebut claims about industry trends. For example, if the defense argues the plaintiff’s job was at high risk of automation, a vocational expert could testify that the plaintiff had specialized skills that a machine couldn’t replicate. It requires a unified strategy from day one of the litigation. The legal implications for someone injured at a busy intersection like West Van Buren Street and North 7th Avenue in downtown Phoenix are now deeply different than they were just last year.
The Impact on Settlement Negotiations
These new rules in A.R.S. Section 12-705 will absolutely change how settlement talks go down. Insurance companies and their lawyers will use the 2.5% wage cap and the new defense-friendly evidence rules to justify lowball settlement offers. Plaintiffs and their attorneys have to be ready for these tactics.
A plaintiff’s best weapon is a rock-solid, compliant lost earnings report from a qualified actuary. That report is the bedrock of the economic damages claim. If it doesn’t strictly follow the new statute, it’s nearly worthless in negotiations, and the claim will be significantly undervalued. The judges in Maricopa County Superior Court, where many of these cases are filed, will be seeing a lot of these new reports, so knowing how they and opposing counsel are likely to perceive these calculations is everything.
Securing fair compensation is still the objective, but the path to get there has become a lot more intricate. It will come down to sharp negotiation backed by bulletproof actuarial evidence and a deep knowledge of the new legal framework. It’s a fight we see in other contexts, too, like the ongoing legal battles over gig worker pay and what constitutes fair compensation. The changes to Arizona law on catastrophic injury claims and loss of income are substantial. Anyone affected needs to get good legal advice quickly and follow these new rules to the letter to protect their financial future.
What is A.R.S. Section 12-705?
It’s a new Arizona law that takes effect on January 1, 2026. It sets out strict rules for how future economic damages, especially lost earning capacity, must be calculated in personal injury lawsuits, including those for catastrophic injuries.
How does the new law affect the calculation of future lost wages?
The law requires that future lost wage projections use accepted actuarial methods. It also means you need an expert who is a licensed actuary or forensic economist. Most importantly, it puts a 2.5% cap on the annual income growth rate unless you can prove a higher rate with “clear and convincing evidence.”
Who is considered a “qualified expert” under A.R.S. Section 12-705?
Under this new law, the only qualified experts for projecting lost future earnings are licensed actuaries or forensic economists whose work can be shown to follow generally accepted actuarial principles. A general economist won’t cut it anymore.
Can a defendant challenge my claim for lost income under the new law?
Yes, absolutely. A.R.S. Section 12-705 explicitly gives defendants the right to introduce evidence to challenge a plaintiff’s income projections, such as pointing to instability in a plaintiff’s job history, the risk of automation in their industry, or general economic forecasts.
What documentation is important for proving lost earning capacity under the updated Arizona law?
You need to gather as much financial documentation as possible. This means at least five years of tax returns (W-2s and 1099s), pay stubs, employment contracts, performance reviews, promotion letters, and any records showing bonuses, commissions, or benefits. This paper trail is the foundation of the claim.
