How sales tax impacts your pricing strategy

Every FP&A team has been there: pricing gets offered to a client by GTM or product and tax gets treated as a checkout afterthought, only to impact margin and deal value down the line. And with state, county, and city taxes stacking on top of each other, failing to consider tax in your pricing strategy can turn a lucrative deal into a loss-maker overnight.

Sales tax is particularly complex for SaaS and eCommerce companies, as tax laws across 10,000+ state, county, and even city-level jurisdictions can vary significantly. Deciding how sales tax should factor into pricing and aligning on the best approach with stakeholders across the organization are strategic priorities for finance and accounting teams.

In this article we’ll explore how high-growth organizations should be considering sales tax as they design their pricing strategy, providing frameworks for deciding whether to absorb or pass on sales tax and how to build tax into your pricing.

Key takeaways

• For high-growth SaaS and eCommerce sellers, sales tax should be considered as a pricing input, not an afterthought.
• The decision of whether to absorb tax or pass it on to the buyer is a margin decision for the seller, not a display preference.
• For B2B sellers, exemptions and the mix of taxable and non-taxable items mean your taxable base may be smaller and more variable than a single blanket price assumes.
• Uncollected tax compounds into an unrecorded liability that surfaces in an audit or during diligence.

Sales tax is a pricing decision, not just a compliance task

As sales tax for software and subscription goods varies widely across jurisdictions, where you sell can notably impact your effective price and margin. This emerged after the 2018 Wayfair ruling, in which the Supreme Court ruled that states can require sellers to collect sales tax based on economic activity alone, even without a physical presence.

Looking beyond South Dakota, taxability varies widely across the country. Twenty-five states tax SaaS in some form, while Alaska, Delaware, Montana, New Hampshire, and Oregon have no statewide sales tax. Meanwhile tax rates stack across state, county, and city levels, so the same subscription price can carry a different real price depending on exact location.

With all these factors at play, organizations need to consider whether to include sales tax in pricing model strategy or add it at checkout. Sellers collect sales tax from buyers and remit it to the state, so it never comes out of the seller’s pocket unless the seller chooses to absorb it. Either way, tax variability can make or break the viability of any deal.

Should you absorb tax or pass it through?

A key decision in tax pricing strategy is whether to offer tax-exclusive pricing, in which tax is passed to the customer; or tax-inclusive pricing, in which tax is absorbed by the seller.

Passing tax through

Tax-exclusive pricing is standard practice for US B2B organizations. By offloading tax to the buyer, you can protect your margin across varying jurisdictions and keep your headline price clean.

That said, offloading tax to the customer can add friction to the buying experience, particularly in self-service buying flows. Last minute tax additions can turn users away just before conversion.

It’s worth noting that passing tax to the customers is more complex in some jurisdictions than others. Washington’s B&O tax is levied on the seller and generally can’t be passed on to the customer, so it hits margin directly and must be built into the base price.

Absorbing tax

Tax-inclusive pricing enables organizations to offer more transparent pricing across jurisdictions. But absorbing tax without recalculating markup can shrink profits instantly and make certain jurisdictions more profitable than others.

A company could, for example, set a flat $100 price and absorb the sales tax rather than adding it on top. This approach is more common on international transactions than in the US, where sales tax is usually itemized separately on the invoice. In this scenario, the company forecasts an 8% margin after delivery and support costs. In a low-tax jurisdiction, like South Dakota, which has a state tax rate of 4.2%, the company would be left with $95.80 in monthly revenue and $3.80 in monthly profit, a viable model. In a high-tax jurisdiction, like Chicago, however, which has a 15% personal property lease transaction tax, the absorbed tax would leave just $85 in monthly revenue against $92 in costs. When tax is absorbed, the same subscription offer can make money in one jurisdiction and lose money in another.

How packaging and unbundling impacts tax

How you package goods and services can change what’s taxable. Bundled services and usage-based add-ons can carry different tax treatment than the core subscription, so a single blended SKU can over- or under-tax parts of the deal.

To navigate this, organizations can state taxable and non-taxable components separately on an invoice and change the taxable base accordingly. But be mindful. In some states, bundling can make otherwise non-taxable SaaS taxable when it's sold together with a taxable component.

The B2B exemption factor most pricing models ignore

If the decision of whether or not to absorb tax wasn’t complex enough, remember this: not all segments of your customer base are taxed in the same way.

Certain B2B buyers, like resale, nonprofit, or government-exempt organizations, can claim sales tax exemption. Upon purchase, they provide the seller with an exemption certificate that serves as evidence that sales tax doesn’t need to be collected (more information on exemption certificate management here).

If you build sales tax into your pricing, exemption certificates matter. (Tax-inclusive pricing is less common in the US, and sellers that use it need to review the rules in each state where they sell.) An exempt customer is pure margin (as you’re not required to tax them) but a taxable customer in a high-tax jurisdiction eats into your profit. If you don’t forecast for exempt organizations in your pricing strategy, your model could be mis-calibrated.

And don’t forget, certificate management is critical when servicing tax-exempt organizations. Fail to provide a valid exemption certificate for a tax-exempt sale, and auditors will hold you responsible for paying the tax you never collected plus penalties and interest. Missing or invalid exemption certificates in multistate environments are a frequent source of exposure.

When pricing choices become a valuation problem

Fundraising and M&A events can be critical inflection points for your company. But sales tax exposure can derail a deal right at the finish line.

In funding-round and acquisition diligence, buyers assess sales tax exposure as a liability, uncollected tax can cut purchase price or trigger escrow holdbacks. Small monthly misclassifications create penalties and interest that compound over time. Based on successor liability, a state can pursue the buyer of a business for the seller's unpaid sales tax.

When sales tax exposure is a factor on the table, buyers will often factor unpaid sales tax into the acquisition price or abandon the deal altogether.

Building tax into your pricing strategy: A checklist

Designing a tax-aware pricing strategy is a combination of financial planning and cross-departmental collaboration. Here’s a checklist you can follow to design a pricing strategy for your organization.

Model revenue by jurisdiction

SaaS is taxed differently across the country, therefore a single blended model hides real variance. Software services are taxed in roughly 25 states, exempt in others, and partially taxed in a few (Texas taxes 80% of the charge, for an effective state rate near 6.6%). Local rates stack on top, with certain cities, like Chicago, taxing as high as 15%.

In pricing planning, model the tax line separately from the price line, making it possible to see your margin in each jurisdiction rather than a blended average.

Decide absorb vs. pass-through per segment and sales motion

Tax-exclusive pricing protects your margin, but it can add friction to the buying experience, especially in self-service conversion flows. If your business serves multiple market segments and sales motions, it may be beneficial to decide whether to absorb or pass-through tax based on each group. For a high-touch, enterprise deal, tax-exclusive pricing may be a non-issue. But for self-service, last minute tax charges could impact your conversion rates at scale.

Track nexus continuously

Since the aforementioned South Dakota-Wayfair ruling, economic nexus can be triggered by sales activity alone regardless of physical presence. Most states have set their economic nexus threshold at $100k or 200 separate transactions, but thresholds do vary across the country and some states have dropped their transaction-count test.

Nexus can also appear through hiring remote employees, particularly important for SaaS and eCommerce organizations building remote teams.

With nexus thresholds varying across jurisdictions, it’s critical for organizations to monitor thresholds as they grow and factor evolving sales tax liabilities into pricing strategy.

Operationalize exemption certificates before they pile up

If a segment of your customer base is tax-exempt, having a process in place to collect, store, and manage exemption certificates is critical. As the burden of proof for sales tax exceptions sits with the seller, being able to provide valid certificates for every exemption is the only way to avoid paying uncollected tax, penalties, and interest.

Collect exemption certificates at the point of sale and validate them on receipt. Investing in an exemption certificate management solution simplifies the process by keeping certificates organized and flagging invalid or expired certificates.

Align finance and GTM to a tax-aware pricing strategy

As different product and service categories can be taxed differently across jurisdictions, the way you bundle offerings is a tax decision as much as it is a GTM decision. In jurisdictions where SaaS isn’t taxable, putting SaaS licenses in a package with consulting, implementation, or training services in a single, non-itemized price can make the entire package taxable.

By separately stating taxable and non-taxable line items on an invoice, you can more accurately reflect the taxable base. Invoice design, therefore, is a cross-functional pricing conversation, not just last-mile billing operations.

As your GTM evolves, ensure new SKUs, bundles, and discount offers are being routed through a tax review before launch. Retrofitting tax adjustments onto a live pricing page or into active deals is far more expensive than aligning cross-functionally before launch.
