AI might be reducing hiring needs, but the savings can disappear quickly when usage costs surge.

A basic AI query cost about $0.04 in 2023. By 2026, a multi-step agentic workflow can cost around $1.20. Meanwhile, per-developer AI consumption increased 18.6 times in just nine months, and the average company now spends 13 times more on AI tokens than it did in January 2025. For startups and middle-market companies, that growth can quietly erode margins, weaken valuations, and create major pressure heading into 2027 budget planning.

JLK Rosenberger’s Rob Flowers explains what is driving the increase and outlines five practical steps companies can take before fall budgeting begins.

NAIC Sale-Leaseback Clarification | Statutory Insurance Accounting 07/28/2026

The NAIC just changed the rules on sale-leasebacks, and if your insurance company pledged collateral on one of those deals, the surplus benefit may need to be reversed.

Effective March 23, 2026, sale-leaseback agreements involving pledged collateral no longer qualify as true sale-leasebacks under statutory accounting. Assets go back on the books. A liability must be recognized. And there are only two paths forward: exit the arrangement and absorb the surplus hit, or seek a permitted accounting practice from your state of domicile.

JLK Rosenberger's Maria Vigul breaks down what changed and what insurers should be doing right now. See how this affects your surplus

How Can Contractors Maximize Vehicle Tax Deductions? 07/22/2026

That $90,000 work truck you just bought? You could deduct the entire cost this year.
Section 179 is at $2.56 million. Bonus depreciation is back at 100%. And heavy vehicles over 14,000 pounds GVWR can often be fully expensed without even touching bonus depreciation. The 2026 vehicle tax landscape is one of the most favorable in years for construction companies.

But mileage log gaps, dropping below 50% business use, or selling a vehicle without accounting for recapture can turn a major deduction into a major tax bill. JLK Rosenberger's Ken Kathcart, CPA, Partner, has the full breakdown.
