You didn’t become an entrepreneur to spend your days parsing tax laws.
You became one because you had a vision, something meaningful you wanted to build. You had energy, ideas, and that relentless spark that wakes you up in the middle of the night thinking about your next product launch, not your next filing deadline. You’re focused on growth. On building something that lasts.
And then, quietly and persistently, sales tax crept in.
Not just in your state. But across a growing map of jurisdictions. And suddenly, something that once seemed like a line item on your to-do list turned into a source of stress, uncertainty, and recurring panic, one you didn’t sign up for.
If that’s where you are, let me just say this: I see you. You’re not alone. And no, you’re not doing it wrong. You’re running a real business, and multi-state compliance is no small thing. It’s complex. It’s confusing. And it’s absolutely manageable with the right support.
How Did We Get Here?
Let’s take a step back. This isn’t just your struggle. It’s a structural one.
The U.S. doesn’t have a national sales tax. Instead, it has more than 12,000 tax jurisdictions across states, counties, and cities each with its own rules, deadlines, and definitions of what “compliance” looks like.
After the 2018 Supreme Court decision in South Dakota v. Wayfair, the game changed completely. States were suddenly allowed to enforce economic nexus, meaning you could be required to collect and remit sales tax in a state just by making enough sales there even if you’ve never been to that state in your life.
This was meant to level the playing field for brick-and-mortar businesses, but for online sellers? It’s often a compliance nightmare. One that gets worse the more successful you become.
So, if it feels like every win (every new customer, every new state you ship to) also brings a wave of new obligations, that’s not your imagination. That’s the system. And it’s why so many entrepreneurs start searching for a tax professional near them or a CPA who understands eCommerce.
What Multi-State Sales Tax Really Feels Like
Here’s what I’ve heard from business owners time and again:
“I just want to know I’m doing the right thing.”
“I’m scared I’m going to miss something and get hit with penalties.”
“I’m spending more time Googling tax deadlines than working on my business.”
That’s the emotional weight behind compliance, something most advisors don’t talk about. But we do.
Because this isn’t just about collecting the right percentages. This is about protecting the thing you’ve worked so hard to build. It’s about avoiding the stress that keeps you up at night and replacing it with systems, knowledge, and guidance that lets you breathe.
At Insogna, we see the numbers but we also see you. We see the stress behind your spreadsheets, the questions you’re too embarrassed to ask, and the pressure of trying to keep it all together. And we’re here to lift that weight.
Three Steps to Simplify Multi-State Sales Tax Without Losing Yourself in the Process
Step 1: Create Your Nexus Map
Let’s start here, because this is where everything else flows from.
Nexus means you’ve established a tax connection with a state. That connection might be physical (like having a warehouse or employee) or economic (crossing a sales threshold).
Each state sets its own threshold. Some say $100,000 in sales triggers nexus. Others say 200 transactions. A few say both. And these thresholds reset annually.
The challenge? Most business owners don’t realize when they’ve triggered nexus. It’s not like a state sends you a friendly email saying, “Welcome, you now owe us sales tax!”
That’s why we build custom nexus maps with our clients. Tracking every state where you’ve sold, calculating where you’re approaching a threshold, and identifying whether your marketplaces are covering your obligations.
Example: You sell candles online. In one year, your Shopify sales in California hit $108,000. Your Amazon sales there are only $12,000, and Amazon remits tax on your behalf. But your Shopify store? It doesn’t.
That means you now have nexus in California and if you’re not collecting tax on your Shopify orders, you’re on the hook.
We’ve seen too many good businesses caught off guard by situations just like this. You deserve better. That’s why our clients get real-time monitoring and quarterly nexus updates so compliance becomes proactive, not reactive.
Step 2: Automate with Confidence, Not Confusion
Yes, automation is powerful. But no, it doesn’t solve everything out of the box.
Tax software like Avalara or TaxJar is designed to help. But these tools are only as good as their setup. If your product taxability is misclassified or your nexus isn’t accurately marked in the system, you could be:
- Collecting too much tax (and creating refund obligations)
- Not collecting at all (and becoming liable for unpaid amounts)
- Filing in the wrong states or missing deadlines entirely
We help clients select and configure tax automation that’s aligned to their specific business model. Not someone else’s. Not a generic template. Yours.
We review your sales platforms, integrate your accounting software, and cross-check every setting against your real nexus map. Because peace of mind isn’t just about having software. It’s about having the right eyes on it consistently.
And if your eyes are tired? That’s okay. We’re watching for you.
Step 3: Build a Compliance Rhythm You Can Trust
There’s a rhythm to compliance. One that we help our clients master without overwhelming them. Because when something becomes routine, it stops being scary.
Monthly, we help clients:
- Review sales by state
- Track marketplace vs. direct platform sales
- Log marketplace remittance confirmations
Quarterly, we guide:
- Nexus re-evaluation
- State registration updates (as needed)
- Zero-dollar return tracking (yes, some states require these!)
Annually, we support:
- Full compliance audit
- Technology stack review
- Strategic forecasting for expanding into new states
This rhythm means fewer surprises. Fewer late nights. Fewer worries.
It means you’re not guessing whether you’re compliant, you know.
And when you have questions (because you will), we don’t make you feel silly for asking. We make space for clarity. That’s what true partnership looks like.
But What If You’re Already Behind?
If you’re reading this with a pit in your stomach, wondering if you’ve already missed something important, please hear this: you can recover.
We’ve helped businesses:
- Backfile up to five years of sales tax
- Negotiate voluntary disclosure agreements with states
- Register retroactively without incurring penalties
- Integrate clean compliance systems going forward
You are not broken. You are not “too far gone.” You are exactly where you need to be to start fresh with the right guidance.
The Deeper Why: This Is About Freedom
This isn’t just about tax.
It’s about restoring your time. Protecting your focus. Reclaiming the space in your brain that’s been hijacked by compliance fear.
You didn’t build your business to live in anxiety. You built it for freedom, purpose, connection, and growth. At Insogna, we hold space for that vision and we fight to protect it.
We’re more than a CPA firm in Austin, Texas. We’re a partner in your expansion. A guide in your moments of doubt. A second brain when yours is at capacity.
Because you deserve a support system that sees your full picture, not just your tax liability.
