If you’ve ever wondered is use tax the same as sales tax, the short answer is no—but they’re closely related. Both are consumption-based taxes applied to the sale or use of taxable goods and services, but they operate differently depending on who collects the tax and when. Sales tax is charged by the seller at the time of purchase, while use tax is paid by the buyer when sales tax wasn’t charged but is still legally owed.
In this article, we’ll break down the differences, explain who’s responsible, and show how Hands Off Sales Tax (HOST) helps you stay compliant on both fronts.
What Is Sales Tax?
Here’s a concise look at what sales tax is and how it functions:
Sales tax is a consumption tax imposed by state and local governments on the sale of taxable goods and services at the point of sale. The seller collects the tax from the buyer and remits it directly to the government, acting as a trusted third-party collector.
Typical examples where sales tax applies include:
- Retail purchases at physical stores or in-state sellers
- Services that the state designates as taxable (e.g. installation, repair, digital services)
Sales tax is determined by the seller’s location or fulfillment location, though remote sellers with nexus obligations must also collect tax based on the buyer’s destination.
Key Features
- Collected at point of sale by the seller
- Rate is usually aligned with the buyer’s state and local jurisdictions
- Seller is responsible for collection and remittance, even if the buyer disputes or fails to pay
Understanding sales tax is critical for both consumers and businesses. It sets the groundwork for comprehending use tax, which applies when sales tax wasn’t collected but should have been.
What Is Use Tax?
Here’s a clear and concise look at what use tax means, and how it differs from sales tax:
Use tax is a complement to sales tax, applied when taxable goods or services are used, stored, or consumed within a state after being purchased from out-of-state vendors who didn’t collect sales tax. Its purpose is to protect local retailers and ensure tax fairness, especially in the era of online commerce.
Key Characteristics:
- Self-assessed and remitted by the purchaser, not the seller
- Rates generally match the state’s sales tax rate, ensuring equitable treatment
- Applies in scenarios such as:
- Online purchases from vendors without nexus
- Items bought tax-free then stored, used, or consumed in-state
At a Glance:
- Use tax covers purchases where traditional sales tax wasn’t collected
- Liability falls on the buyer (individual or business)
- Both types of tax support state and local revenue systems
Understanding use tax is essential, particularly for businesses making large out-of-state purchases or individuals who often shop online. It ensures you’re meeting obligations and avoiding unexpected tax liabilities during audits or tax filings.
Key Differences in Liability & Enforcement
Here’s a breakdown of the most important distinctions between sales tax and use tax, especially in terms of who’s responsible, tax rates, and how states enforce compliance.
Who’s Responsible?
- Sales tax is collected and remitted by the seller, who adds it at the point of sale.
- Use tax is paid by the buyer, who self-assesses and remits directly to the state when no sales tax was charged.
Consumer use tax is especially common for goods purchased out-of-state without seller nexus.
Rate Alignment
- Both taxes typically carry the same rate for a given jurisdiction, maintaining tax parity.
- That includes combined state and local rates. If sales tax is 7%, use tax is generally also 7%.
Enforcement Mechanisms by State
- States are increasing enforcement of sales tax through audit task forces, data-sharing, and pre-audit surveys focused on unregistered or unreported sales.
- Use tax, while harder to enforce, is still pursued in significant cases—especially business purchases or large out-of-state acquisitions. States may audit or cross-check purchase records to catch uncollected tax obligations.
Why It Matters
- Misunderstanding liability can cause businesses or individuals to inadvertently owe use tax when sales tax wasn’t collected.
- Properly assigning responsibility and tracking purchases helps avoid audit risk, penalties, and unexpected tax bills.
- Both business and consumer taxpayers need to remain aware of their respective obligations under each tax regime.
Understanding these distinctions helps ensure compliance, reduce liability, and maintain audit readiness—whether you’re buying, selling, or both.
Practical Scenarios: Use Cases Explained
Use tax isn’t just a legal technicality—it’s a catch-up mechanism that states rely on to ensure tax is paid when sales tax isn’t collected upfront. These scenarios often feel like gray areas to businesses and consumers alike, but the rules are clear. Below are real-world examples that highlight when and how use tax kicks in—even if no one mentions it at checkout.
Example A: Buying from an Out-of-State Seller
You purchase office supplies from a small vendor based in Oregon, a state with no sales tax. They ship the goods to your office in Minnesota and don’t charge tax. But because you’re using the items in a taxable state, you’re required to remit Minnesota use tax yourself.
Example B: Business Imports Equipment for Internal Use
A manufacturing firm imports machinery into California from a wholesaler located in Michigan. Since the seller lacks nexus in California, no sales tax is collected. Yet once the equipment is put into use locally, the business owes use tax—calculated at the same rate as sales tax.
Example C: Digital Services Consumed Remotely
Your design team subscribes to a cloud-based tool from a SaaS provider based abroad. No U.S. tax is applied—but your team uses the service in Wisconsin. That qualifies as taxable use, triggering use tax liability on the subscription value.
Understanding these use cases isn’t just about avoiding penalties—it’s about proactively protecting your business from noncompliance and audit risk.
Impact of Wayfair & Nexus Laws
States used to be limited in taxing online sales—until one landmark case changed everything. In South Dakota v. Wayfair (2018), the Supreme Court ruled that states can require out-of-state sellers to collect and remit sales tax even without a physical presence, overturning decades of precedent under Quill and National Bellas Hess. That ruling paved the way for economic nexus laws, making remote sellers responsible if they exceed thresholds like $100,000 in sales or 200 transactions annually.
Nexus Laws and Remote Seller Obligations
States followed suit quickly:
- Economic nexus: Now, most states enforce tax collection when remote sales surpass specific thresholds—often $100K or 200+ transactions—even if the seller has no in-state store or office.
- This expansion affects both sales tax (collected at sale) and use tax avoidance (purchasers who avoid paying tax on untaxed purchases). Buyers can no longer rely on use tax compliance to cover gaps without seller collection.
- Remote sellers must register in states where they meet nexus criteria—collecting, remitting, and filing accordingly for both sales tax and, when necessary, informing use tax responsibilities.
Why It Matters to You
- Miss the nexus threshold? If you continue selling without registering, you’re at risk of audit, back taxes, penalties, and interest.
- Buyers relying on use tax voluntariness face growing enforcement, including cross-checks on large purchases or business procurement data.
- Understanding nexus laws helps you decide when to register as a remote seller—or proactively avoid use tax risk by staying ahead of thresholds.
States now enforce consumption tax comprehensively. Whether you sell or buy across state lines, knowing where nexus applies is critical to avoiding liability and staying compliant.
Reporting & Compliance Best Practices
When reporting use tax, timing, responsibility, and documentation matter. Getting it wrong can lead to penalties and audits—so a proactive approach is vital.
When to Self‑Report Use Tax
You should self-assess and report use tax when you buy taxable goods or services from vendors that didn’t collect sales tax, particularly:
- Out-of-state or catalog purchases
- Software or digital subscriptions, if consumed in your state
- Items withdrawn from inventory or used internally without tax being paid
Business vs Consumer Responsibilities
- Businesses: Must report use tax via their regular sales & use tax return, even without a registered seller permit. In some states, high use tax liability requires business registration specifically for use tax
- Consumers: Typically report use tax through their state income tax return or a separate form. Some states offer simplified reporting or lookup tables for smaller purchases
Recordkeeping & Audit Readiness
- Keep thorough records for all transactions where sales tax wasn’t collected—especially invoices, receipts, or exemption certificates.
- Maintain clear documentation of out-of-state purchases or digital service subscriptions showing value and date of use.
- States often audit large purchasers or businesses with frequent untaxed purchases; clean records reduce audit risk and simplify responses.
Quick Best Practices Summary
- Track purchases month‑to‑month and estimate use tax liability.
- Report use tax regularly—even for small or occasional purchases.
- Retain documentation for at least 3–5 years to support tax positions.
- Regularly review purchases to identify potential use-tax liabilities and avoid surprises during tax filings or audits.
Being proactive helps both individuals and businesses ensure full compliance—and maintain audit-ready records whenever questions arise.
Common Misconceptions & Compliance Pitfalls
Many businesses and consumers believe use tax is optional or irrelevant—until a notice arrives. Clearing up these misconceptions and being proactive can save you from back taxes, penalties, and audit headaches.
1. Myth: Use Tax Is Optional If Sales Tax Wasn’t Charged
This belief is widespread but false. States expect use tax payment when sales tax wasn’t collected—even if the purchase was online or from a remote vendor. Failing to self-report what you owe can trigger penalties, interest, and audit scrutiny.
2. Tax Rate Confusion Between State and Local Jurisdictions
Retailers sometimes collect only state-level rates, especially for online purchases, leaving buyers liable for local excise or district taxes. While sales and use tax rates often match, local add-ons still apply—buyers should check combined rates for accuracy.
3. Not Tracking Out-of-State Purchases Systematically
If your purchases from out-of-state vendors aren’t tracked monthly, it’s easy to overlook cumulative liability. Missing even small purchases can add up over time, increasing audit and penalty risk. Best practice: Review vendor invoices or credit card statements monthly to catch potential use tax exposure.
Quick Compliance Tips
| Pitfall | How to Avoid It |
| Assuming use tax is optional | Always consider use tax liability when sales tax is not collected |
| Underestimating local rates | Check combined state & local rates for each jurisdiction |
| Inconsistent tracking | Reconcile purchases from all vendors monthly for use tax exposure |
Avoiding these common pitfalls will help you stay compliant and minimize surprises—whether you’re a business or a consumer.

Frequently Asked Questions (FAQs)
1. Is use tax the same as sales tax?
No. While both are assessed at the same rate, sales tax is collected by the seller, whereas use tax is self-reported by the buyer when no sales tax was charged on a taxable purchase.
2. When am I responsible for paying use tax?
You must pay use tax when you purchase a taxable item or service without sales tax, typically from an out-of-state or online seller that doesn’t have nexus in your state. This applies to both businesses and individuals.
3. Are digital products subject to use tax?
Yes, in many states. If you buy software, data, or cloud services from a vendor that doesn’t collect your state’s sales tax, you may owe use tax. Rules vary by state, so it’s important to verify classification.
4. How do I report and pay use tax?
Use tax can typically be reported through your state’s Department of Revenue portal or as part of your business’s regular sales and use tax return. Consumers may report it on personal income tax filings in some states.
5. What happens if I don’t pay use tax when it’s due?
Failing to pay use tax can result in penalties, interest, or audits—especially if your business regularly purchases goods without sales tax. Many states are increasing enforcement and cross-checking purchases during routine audits.
