Government Contracting

Busy government contractors can trust their accounting, audits, and taxes to us—gaining time and peace of mind.


Thompson Greenspon has guided government contractors since 1956. We help small startups to large companies throughout the lifecycle of their business, serving rising stars in technology, communications, defense, security, and professional services.

You can count on exceptional service from the same partner and staff over the long term. Our continuity enables us to understand your business and keep you advised of changing compliance regulations. This expertise gives you peace of mind and time to focus on running your business. Whether you’re seeking your first contract, starting research and development, or pursuing a merger or acquisition and a smooth exit, we can assist you.

“Having Thompson Greenspon handle my taxes is, frankly, a relief for me, as I absolutely KNOW the taxes will be prepared in a timely manner (assuming I provide the material also in a timely manner) and every effort will be made to ensure a good, honest, and fair tax “result”.  I’ve also had questions answered concisely and quickly about what is/is not tax deductible if I did not understand it via online or other searches. Now that I am retired this is even more important.”
