About Us

Tax Hack Accounting Group is a tax advisory firm focused on internet, software, and e-commerce businesses.

Our mission is to provide a first-rate client experience by delivering the best tax advice and tax savings available to your business.

As a fast-growing tax company ourselves, we understand the challenges your business faces. By working with us, you can expect us to help organize your compliance so you can move to more strategic and planning-level items that have 10X+ returns.

We focus heavily on delivering a seamless experience: our workflow keeps your data safe via our client portal, up to date on all deadlines through quarterly meetings, and on track with federal and state requirements.


What do tax geeks, surfers, and code heads 
all have in common?


We all pay taxes.


At Tax Hack, we’re a team that’s committed to changing how we think about and approach our personal and business financials.


In a recent client survey, business owners and investors shared that on average 72% of them felt they were “Significantly Compliance Focused.” While compliance is critical to any finance team, we aim to move our C-suite counterparts, controllers, and operators to a forward-thinking approach, identifying key goals in the business, processes, and financial targets that provide key insights into the “black box” of accounting, tax, and treasury.

Who We Are

Miguel Alexander Centeno

Managing Partner 

After six years of consulting Fortune 500 companies with tax giant PricewaterhouseCoopers, Miguel left management at the “Big Four” with one goal: to make tax strategy accessible to anyone willing to learn and implement a good idea. Since starting Tax Hack, he has built a team fully focused on learning, educating, and executing tax strategies that provide clients with 10X savings through a first-rate advisory experience.

Miguel is designated by the Internal Revenue Service to represent taxpayers in all matters before the IRS and in the United States Tax Court. He has been featured in the Wall Street Journal, Fox Business, and MSNBC on tax policies and best practices. During key Congressional hearings that preceded the 2018 Tax Cuts and Jobs Act, Miguel testified before the U.S. House Committee on Small Business as an expert witness.

Miguel leads the Firm’s National Executive Council and the Central Mountain Region and advises clients across all lines of service. He is based in Austin, Texas where he resides with his wife Andrea, two kids, and three cats. When not in a tax memo or firm administration, Miguel can be found yelling on the sidelines at his kids’ games and searching for new BBQ spots (recommendations always welcome).
