WHY SPARTAN TAX GROUP

Most CPA firms sell outputs.

We deliver outcomes.

You are not a client here. You are a member. That distinction changes everything — how we work, how we charge, and how deeply invested we are in your success.

The traditional model is broken. Firms charge by the hour, disappear between tax seasons, and treat every interaction as a billable moment. We built Spartan Tax Group to be the opposite — a firm where the relationship comes first, and deliverables are simply the byproduct.

“

Gone are the days of sitting on a question because you’re worried about the bill. Pick up the phone. That’s what we’re here for.

Brentley Leitzell, CPA — Founder

Quarterly Estimated Taxes Explained

Quarterly estimated taxes are one of those things that can feel simple in theory and frustrating in real life. The IRS says tax is generally a pay-as-you-go system. Employees usually handle that through payroll withholding. Business owners, self-employed taxpayers, partners, S-Corp shareholders, landlords, and investors often need another system because there may not be enough […]

What Is an FBAR? Foreign Account Reporting Basics

Foreign accounts can create U.S. reporting requirements even when no foreign tax is due. The FBAR is often the first international tax form people need to understand.

Frequently asked questions.

A few things people ask before becoming a Spartan Advantage member
How does membership pricing work?
Spartan Tax Group runs on a flat monthly membership, not hourly billing. You choose the tier that matches your complexity, and that single fee covers your returns, your planning, and your access to us. No surprise invoices, no meter running on phone calls or emails.
Yes. Most new members join outside of tax season. We’ll review your prior returns and current books, get you fully onboarded, and make sure nothing falls through the cracks during the transition from your previous accountant. Just setting up a new business? We’ll help with a clean set up to ensure your business runs as efficient as possible so you can focus on building your business.
No. That’s the entire point of Spartan Advantage membershio. Pick up the phone whenever something comes up – a question about a purchase, a notice in the mail, a decision you’re weighing – and it’s already covered.
Not at all. We’re based in Land O’ Lakes and proud to call Tampa Bay home, but our work isn’t limited by geography. Through the Spartan Portal and secure virtual collaboration, we serve clients across the country and around the world – from straightforward individual returns to complex business and cross-border matters. Wherever you are, you get the same year-round access and direct relationship with your CPA as someone walking through our front door.
