The retailer, its sales figures and the classmates are composites; the textbook, the court case, Scripture and the research cited are real.

Granite Peak Supply is an Idaho company that sells hiking and climbing gear through its own website. It has no warehouses, offices or employees outside Idaho, and it ships about $2.4 million of goods a year to customers in 41 states. Its largest out-of-state markets look like this:

The owner asks a simple question: does Granite Peak have to collect sales tax in states where it has never set foot? She also wants to know what happens to the sales the company has already made without collecting tax.

Spilker et al. (2018) explain that a state can impose a tax collection obligation only on a seller with nexus, a sufficient connection to the state. For decades, sales tax nexus required physical presence. In South Dakota v. Wayfair, Inc. (2018), the Supreme Court overruled that rule and upheld a South Dakota law requiring remote sellers to collect tax once they made more than $100,000 of sales or 200 separate transactions into the state in a year. Every state with a general sales tax has since adopted an economic nexus standard, although the thresholds differ, and several, including South Dakota, have dropped the transaction count.

Applying a $100,000 sales threshold, Granite Peak has nexus in States A, B and C and probably in several of the remaining 37 states where its sales are concentrated; State D falls just below the line this year but would cross it with 5% growth. In each state where it has nexus, the company must register, collect tax at the rate for the customer's location and file returns. A business can owe tax in a state it has never visited, because the measure of presence is now the market, not the building. Sales Granite Peak makes through an online marketplace are a different matter, since most states now require the marketplace facilitator to collect the tax on those sales. For past sales in states where nexus already existed, many states offer voluntary disclosure agreements that limit the look-back period and waive penalties, which is usually cheaper than waiting for a notice.

The policy stakes are real. Agrawal and Fox (2017) describe how the growth of electronic commerce eroded state sales tax bases and made the treatment of remote sellers central to the tax's survival. Baugh et al. (2018) studied the period when Amazon began collecting sales tax in several states and found that households in those states reduced their Amazon purchases by 9.4%, which implies that buyers are highly sensitive to whether tax is collected at checkout. For Granite Peak, collecting tax may cost some sales, but the obligation is not optional once nexus exists. Sales tax automation software can calculate rates by address and file returns in each state, which brings the compliance cost within reach of a small seller.

Romans 13:7 includes taxes and revenue among the debts believers are to pay to those owed them (English Standard Version Bible, 2001/2016). In a small company's case, that may mean the tedious work of registering in a dozen states. An adviser who helps the owner comply honestly, rather than waiting to be caught, serves both the client and the communities whose schools and roads the tax supports.

Mason, your thread focused on why an S corporation's owners pay tax on its income at the individual level, and I would add one way that state taxes interact with that rule. Because the federal deduction for state and local taxes is capped for individuals, many states created elective pass-through entity taxes, which let an S corporation or partnership pay state income tax at the entity level. The entity deducts the tax as a business expense in computing the income that flows through, and the owners receive a credit or exclusion on their state returns. The result is that the state tax becomes a deduction the cap does not reach, which can be worth thousands of dollars to an owner in a high-tax state. The IRS confirmed in Notice 2020-75 that such entity-level payments are deductible by the entity, and although the July 2025 federal law raised the individual cap, it left the entity-level approach available. For an S corporation owner with $800,000 of income in a state with a 6% rate, the entity could pay $48,000 of state tax and reduce the owner's federally taxable pass-through income by that amount. Spilker et al. (2018) explain that S corporation items retain their character and pass through pro rata, so the deduction reduces each owner's share in proportion to ownership. The election is not always beneficial, since some states do not give a full credit to nonresident owners, so I would suggest modeling it for each owner before electing. The model should include the owners' home-state credits.

Abigail, your thread suggested that once a remote seller has sales tax nexus in a state after Wayfair, it also owes that state's corporate income tax. The two questions are related but governed by different rules. Spilker et al. (2018) explain that a federal statute, Public Law 86-272, prohibits a state from imposing a net income tax on a business whose only activity in the state is soliciting orders for sales of tangible personal property that are approved and shipped from outside the state. Granite Peak, which sells physical gear from Idaho, may therefore owe sales tax collection in State A while remaining protected from State A's income tax. The protection has limits. It does not apply to services or digital products, it does not cover gross receipts taxes, and some states now take the position that certain internet activities, such as placing cookies to gather data, go beyond solicitation. Many states have also adopted economic nexus standards for income tax, but those standards still yield to Public Law 86-272 where it applies. Baugh et al. (2018) showed how sensitive buyers are to sales tax collection, and income tax adds a separate compliance cost, so the distinction matters for small sellers. Even a seller with no income tax filing obligation may still need to file information reports in some states. I would suggest adding a two-column table to your thread listing sales tax and income tax status separately for each state where the business has customers. That table would show the client at a glance where it must register for which tax.
