Precision Tax Guidance Built for Your Business

Navigating sales and use tax across multiple states can be incredibly complex — and relying on generic research tools often leads to costly errors. With frequent changes in tax law, varying definitions of nexus, and industry-specific rules, a one-size-fits-all solution just doesn’t cut it. That’s why Tax-Mac LLC offers a Custom Sales and Use Tax Matrix — a highly tailored roadmap built specifically around how your business operates, buys, and sells across jurisdictions.

What Is a Custom Tax Matrix?

A Custom Tax Matrix provides detailed taxability determinations for your specific products or services across each relevant state and local jurisdiction. While basic tools offer high-level guidance based on broad categories, our approach dives deeper — accounting for:

  • The intended use of the item or service

  • The state and local regulations that apply

  • Your business’s operational nuances and footprint

This matrix ensures you’re fully informed and tax-compliant — not just in general, but down to the detail of each transaction type.


Why a Custom Matrix Is Essential

Unlike generic tax charts or lookup libraries, our matrix is:

  • Built for your unique business – No assumptions, just accuracy

  • Clear and user-friendly – Written in plain language with context, examples, and footnotes

  • State and local aware – Covers laws across jurisdictions, not just at the state level

  • Audit-ready – Every determination is backed by source-based research and comes with audit defense support

  • Supported by Experts – Includes free training sessions and ongoing help from our Tax Help Desk


Who Benefits from a Custom Tax Matrix?

We’ve helped clients across various industries streamline compliance, reduce risk, and avoid overpaying:

  • Construction Firms: Addressing subcontractor and equipment taxability across project sites

  • Alcohol & Hospitality Companies: Handling location-based liquor licensing and tax requirements


Built on Research, Not Assumptions

We don’t rely on outdated tools or rigid software — every matrix is crafted by experienced tax researchers and tailored to your needs.

How often does the matrix need to be updated?

Sales and use tax laws change frequently. While the matrix is designed to be long-lasting, we recommend periodic reviews or updates, especially if your business expands into new states, adds new products, or if significant tax law changes occur. We can assist with ongoing support and updates as needed.

Will the matrix help during a sales tax audit?

Yes — absolutely. Each determination in your custom matrix is backed by documented research and legal references. If a state auditor challenges any item, we provide full support and defend the position at no additional cost.

What makes a Custom Sales and Use Tax Matrix different from online tax tools?

Online tools typically provide general, category-level guidance that may not account for how a product or service is used — or how tax rules vary at the local level. A Custom Matrix from Tax-Mac is built specifically around your business operations, product lines, and jurisdictions, offering detailed and accurate taxability determinations.

How long does it take to complete a Custom Tax Matrix?

Project timelines vary depending on the number of products/services and jurisdictions involved. On average, most matrices are completed within 3 to 6 weeks, including a detailed scoping session, in-depth research, and a final training call with your team.
