Lucasys

Tax teams do not want to explain their business from scratch every time they need help. Every member of the Lucasys team has deep experience in tax and utilities, across finance, technology and regulation, and that experience is built into the software and into the support behind it. One call, and you are talking to someone who already understands the work. It is why teams come to rely on Lucasys, and why they keep trusting it.

Lucasys has been named the No. 46 fastest-growing private software company in America on the 2026 Inc. 5000 list, and No. 472 overall. The ranking measures revenue growth from 2022 to 2025, the years in which more than thirty leading energy and utility companies across North America chose Lucasys as their modern tax system. "Ranking among the top 50 software companies in the country is a testament to the success of our customers and to the best-in-class software our team delivers," says Vadim Lantukh, Co-Founder and CEO.

Energy tax teams face growing pressure from complex rules, large data sets, and tight deadlines. They need support that understands the demands of asset-intensive industries. Enter Lucasys AI. Lucasys AI is an interactive, agentic AI designed to meet the specific needs for energy tax. These agents help teams manage reporting requirements, guide daily tax workflows, and analyze complex data with confidence. Embedded directly in your tax system, they strengthen accuracy, speed, and insight across every process.

Utilities, energy and oil and gas companies carry some of the largest fixed asset bases in the economy, and their tax work rarely fits in one tool. The Lucasys Income Tax Suite does: Tax Depreciation, Deferred Tax, Tax Provision, Tax Basis Balance Sheet and Tax Repairs in one modern system, built on a clean core with transparent calculations and direct SAP and Oracle integration. Lucasys AI works across every application. Five applications, one system, no black boxes.

Tax and fixed asset teams at utilities and energy companies do some of the most specialized work in finance, and they rarely get time in a room with peers who do the same work. The Gathering changes that. Lucasys customers, employees and partners meet at Nobu Hotel Atlanta on March 21 to 23, 2027 for practitioner-led sessions, product roadmap previews and CPE credits. Early bird registration is $695 until November 30, then $995, with all sessions, meals and evening events included. When your team asks to go, this is why to say yes.

American Electric Power, one of the largest electric utilities in the United States with 5.6 million customers across 11 states, has chosen Lucasys for tax depreciation and deferred tax. At that scale every calculation has to be traceable and every result has to hold up under audit and regulatory review. Lucasys delivers that with transparent calculations, automation and direct integration with the systems AEP already runs. Read how AEP is modernizing its tax foundation.
