Overpaying Sales Tax? Here’s how to recover your capital

Frequently Asked Questions

Why do I suddenly have all these sales and use tax liabilities?

If your business has recently expanded to another state, or if you are purchasing or selling a company that operates in multiple states, you may be incurring these liabilities without realizing.

How does Aprio help with sales tax nexus?

We analyze your business activities to determine where you have nexus and what tax rules apply.

Can Aprio handle sales tax filings for me?

Yes, we prepare and file your sales tax returns to keep you compliant and help avoid penalties.

Does Aprio work with e-Commerce businesses?

Absolutely—our team helps online sellers navigate state sales tax rules and marketplace facilitator laws.

What if my business is already behind on sales tax?

Aprio can assist with audits, voluntary disclosures, and payment plans to get your business back on track.

How often should sales taxes be filed?

Filing frequency depends on state requirements—monthly, quarterly, or annually—but don’t worry. Aprio can manage all of it for you.

What’s the difference between sales tax and use tax?

Sales tax is collected by the seller at the time of sale. Use tax is self-reported and paid by the buyer when sales tax wasn’t collected — often in out-of-state or online purchases. States use both to help ensure proper tax on taxable transactions.

What happens if I didn’t collect sales tax and should have?

You could be liable for back taxes, penalties, and interest — and states may audit several years back. However, options like voluntary disclosure agreements (VDAs) may limit your exposure and help you come into compliance proactively.

What is a voluntary disclosure agreement (VDA)?

A VDA is a method for resolving state tax exposure for prior periods that permits a taxpayer to approach a state and disclose unpaid taxes. In return, the taxpayer can receive valuable benefits including a limited look-back period (i.e., all tax exposure prior to that period is forgiven) and penalty waivers. Aprio’s SALT team can guide your business through every step of the VDA process to help resolve liabilities and ensure future compliance.

How do sales tax overpayments happen?

They often occur from misapplied tax rates, exempt transactions being taxed, or complex multi-state rules.

What happens if I overpay my sales taxes?

Due to complex tax regulations and fast-changing state laws, it’s fairly common for companies to accidentally pay more than they should on sales tax. But don’t worry—Aprio can help you review transactions, communicate with vendors or states, and implement best practices to maintain future compliance.
