Florida Roots. National Reach.

The Numbers Matter.
So Does The Judgment.

I work where finance, federal taxation, business and public policy meet. My aim is to make the facts understandable—and the next decision a better-informed one.

I’m Paul Diaz: business owner, IRS Enrolled Agent, author, educator and City Commissioner. Different settings. The same respect for the people whose money and future are at stake.

Professional education. Practical perspective. A clear way forward.

A Career Connecting The Pieces

Finance Is The Foundation.
Understanding Is The Point.

Business decisions do not arrive neatly separated into accounting, taxes, family priorities and public policy. They arrive as life. The useful work is connecting the pieces.

Paul D. Diaz holds an undergraduate degree in Finance from the University of Miami and a Master of Business Administration with a concentration in Accounting. Across undergraduate and graduate business studies, he completed more than 150 hours of business and accounting coursework.

He chose a path through business management consulting and federal tax practice, bringing business strategy and tax strategy into the same conversation. As an IRS Enrolled Agent, he is admitted to practice before the Internal Revenue Service, including examinations, collections and appeals.

His background also includes college-level teaching of quantitative methods. The lesson carries into his writing and professional work: an answer matters more when people understand the facts, assumptions and reasoning behind it.

Today, that perspective connects THE TAX CUTTERY’s professional work, his books and educational resources, and his service as Winter Springs City Commissioner for District 1.

The Classroom. The Lecture. The Written Explanation.

Don’t Just Give The Answer.
Make The Reasoning Clear.

Teaching quantitative methods means organizing facts, examining assumptions and explaining how a result follows. That same discipline belongs in a business discussion, a tax explanation and a conversation about public money.

My educational work gives readers and audiences a way to understand the question before deciding what to do about it. Use the topic libraries and videos below to keep learning between conversations.

Commissioner Paul Diaz · City Of Winter Springs

Public Money.
Public Responsibility.

A public budget is more than a column of numbers. It reflects priorities, trade-offs and commitments that people live with.

My public-service perspective begins with fiscal responsibility, understandable information and accountable decisions.

Serving District 1.

Paul was elected to the Winter Springs City Commission in November 2024. His current term expires in November 2028. A native Floridian raised in South Dade, he has made Central Florida home for more than 25 years.

A Few Useful Answers.

Who Is Paul D. Diaz, EA, MBA?

Paul D. Diaz is an IRS Enrolled Agent, author, business and tax strategist, and the founder of THE TAX CUTTERY. He holds an undergraduate degree in Finance from the University of Miami and an MBA with a concentration in Accounting. His background includes business management consulting and college-level teaching of quantitative methods. He also serves as Winter Springs City Commissioner for District 1.

What Does Enrolled Agent Mean?

An Enrolled Agent has unlimited representation rights before the IRS, including examinations, collections and appeals, subject to professional rules and client authorization. It is a federal tax credential. Admission to practice before the U.S. Tax Court is a separate qualification.

Where Should I Start With A Tax Question?

Start with THE TAX CUTTERY’s free prerecorded tax consultation for tax preparation, IRS concerns or tax planning. It collects the context behind your question and helps identify the next step. No book purchase or paid live appointment is required to begin. Return preparation, representation, research and Tax Advisory are separately scoped.

How Is Financial Coaching Different From Tax Advisory?

Financial Coaching focuses on budgets, debt, financial habits and your broader financial picture, and begins with its own initial interview. Tax Advisory concerns tax planning and research and follows the tax consultation path. The Guide is recommended for coaching and required for Tax Advisory; it is optional for return preparation.

Are The Companion Books And Classes Available?

The expanded standalone Long Haul and Real Estate Companion editions are in development and are not open for purchase or preorder. The existing trucking page separately explains its verified Guide-owner First Edition and Form 2290 preparation program. Planned classes are not approved CE and are not open for registration.

Where Can I Find Commissioner Paul Diaz’s Official City Information?

Use the City of Winter Springs official Commissioner Paul Diaz page for his District 1 office information. He was elected in November 2024 and his current term expires in November 2028. This personal website and the professional businesses it links to are separate from the city’s official website.
