At T. S. Allen & Associates, we’ve built a strategic, high-quality tax and accounting firm focused on helping business owners plan ahead — not just react during tax season.
We hear it all the time:
"My last accountant never gave me proactive advice."
"I only heard from them when something was due."
"I was hit with a surprise tax bill I could’ve avoided."
Sound familiar? We do things differently.
Our firm is designed to work year-round with business owners, providing timely tax planning, meaningful financial insights, and ongoing collaboration. We believe in taking action before the year ends — while there's still time to make impactful decisions that reduce your tax liability and strengthen your financial position.
No more last-minute scrambling. No more guessing. Just clarity, strategy, and results. In fact, for many of our clients, we have their business financials ready to file in January — well before tax deadlines arrive.
