The Fine Print of Access: The 2021 Digital Goods Sales Tax Shake-Up1:40–2:30 p.m.
In late 2021, the Wisconsin Department of Revenue made a quiet but significant shift in how digital goods—particularly News and Information Products—are taxed. Without legislative action or court rulings, Publication 240 was revised to focus on taxing access rather than the content itself, with far-reaching implications for information databases, even those with only historical data.
Join Holly Hoffman, founder of Sales Tax Advisory Network and former WI Dept. of Revenue auditor, as she breaks down what changed, why it matters, and how accountants can adapt to this evolving tax landscape. With 15 years of expertise, leadership roles in tax policy, and recognition from Digital Journal, CEO.com, and the Founders Future podcast, Holly brings clarity and actionable strategies to a complex topic.

Home Service Happy Hour w/ Dan Platta Podcast
2026-01-14 20:00 - 21:00
Clarity Creates Real Progress
I was a guest at Home Service Happy Hour podcast, we talked about why business owners get stuck in the weeds and how an outside perspective creates instant clarity. When you step back and see the numbers the way an auditor does, everything gets simpler. Clarity leads to better systems, stronger teams, and real productivity.

Listen Now!

Hey there, Home Service Homies!
In this episode, we dive into sales tax confusion that trips up home service businesses every single day. I’m talking with Holly Hoffman, the Sales Tax Lady, about why sales tax feels scary, how contractors accidentally get it wrong, and what actually matters when the state comes knocking. If you run a service business and hope sales tax just takes care of itself, this conversation is going to wake you up.
We get into real stories from audits, CRMs, field techs making tax decisions, and how small mistakes quietly turn into big liabilities. We’re breaking down how to set your systems up so your team is not guessing, your invoices make sense, and you stop bleeding money in penalties or overpayments. If you want clarity, confidence, and fewer letters from the Department of Revenue, this episode is for you. https://salestaxlady.com/

Contractors: Ready to Finally Demystify Sales Tax on Commercial Installations?

If you’ve ever asked yourself,
“Wait… is this a building function or a trade fixture? And why does the sales tax rulebook hate me?”
—you’re not alone!

Join us for a fast‑paced, eye‑opening session on building function vs. process function (trade fixture) installations in commercial facilities. We’ll break down the confusing stuff, tackle real examples, and make sense of the rules that always seem to trip up contractors.

Expect:

Clear insights on building vs. process functions
What counts as a trade fixture (and why it matters!)
How the classification impacts your tax obligations
A lively discussion with plenty of “Ohhhh… now I get it!” moments

It’s a tricky topic—but we’re going to make it surprisingly fun.

Bring your questions. Bring your scenarios. Leave with clarity.
