McMullen Tax Services is a husband-and-wife–led practice based in Palestine, Texas. The firm is led by John Wisener, Enrolled Agent (EA)—the only federally authorized tax credential that permits full representation of taxpayers in all 50 states. For more than 40 years, John has helped individuals, families, churches, ministries, and businesses file accurately, plan ahead, and resolve IRS issues with clarity and integrity. He’s known locally as the “Tax Doctor” for his habit of diagnosing the real problem, explaining options in plain English, and building durable solutions—not one-season fixes.

Accounting Services
Our Story & Background
How We Work
Our process is straightforward and transparent:
Discovery & Intake: We review your prior return, current documents, and goals.
Line-by-Line Review: We explain what affects your refund or tax due and identify missed opportunities.
File & Defend: Returns are e-filed with confirmations; if the IRS has questions, we handle them.
Plan Ahead: We adjust withholdings, estimates, and timing to reduce surprises next year.
We communicate on your terms—phone, text, and Instagram—and John returns calls. Taxes don’t stop after April 15, and neither do we.
Who We Serve
While we’re proudly based in Palestine, we support clients across East Texas—including Tyler, Jacksonville, Athens, Crockett, Corsicana, Lufkin, Nacogdoches, Longview, and Huntsville—and represent taxpayers nationwide. We’re a strong fit for families, churches and ministries, organized, established businesses, new workforce entrants, and agricultural operations.
Careers at McMullen Tax Services
We keep a small, focused team and value professionalism, accuracy, and calm under pressure. If you’re an experienced tax preparer, bookkeeper, or payroll specialist who believes in documentation, ethics, and client education—and you’re comfortable supporting clergy or ag clients—introduce yourself. We review interest year-round (seasonal and part-time inquiries welcome).
Our Values
We build every return from the source documents up—no shortcuts, no guessing. If a number isn’t supported, we don’t use it. You’ll see exactly how each figure is calculated so your return is both accurate and defensible.
Individual return prep starts at $185; final pricing is based on forms and complexity. Quotes for preparation work are free. Advisory deposits are $100 for individuals and $200 for businesses, and they’re credited to your project if you move forward—no surprise charges, ever.
We explain what we file and why, in plain language. Expect a quick walkthrough of key lines, credits, and deductions so you can make smarter decisions on withholdings, estimates, and timing next year.
As an Enrolled Agent, John can represent you directly before the IRS in all 50 states. We handle notices, calls, and documentation, keep deadlines on track, and communicate status clearly so you’re never guessing about next steps.
We prepare student returns at no charge and provide financial-literacy sessions for local schools and groups. It’s our way of building confident, long-term relationships with families across East Texas.
Clergy & Agriculture
A Note on Special Expertise
Clergy compensation and housing allowance have unique rules and pitfalls—John’s 25+ years in ministry mean those details aren’t an afterthought. Likewise, agricultural clients face seasonal cash flow, equipment timing, and depreciation choices that can materially change outcomes. We build plans that reflect the work you actually do. We’re rooted in the community as active members of the Palestine Chamber and local ambassador programs. John regularly presents tax and financial-literacy sessions to area high schools and prepares student returns for free, building trust with young adults as they enter the workforce and establishing multi-generational relationships with their families.
