Economic nexus rules have evolved significantly since the Supreme Court decision in South Dakota v Wayfair. When states first implemented nexus laws after the ruling, many adopted similar frameworks based on revenue and transaction thresholds.
Over time, several states have modified their economic nexus laws by adjusting revenue limits, removing transaction thresholds, or refining compliance requirements.
Understanding these changes helps businesses remain compliant as sales tax regulations continue to evolve.

Why States Update Nexus Laws
Sales tax laws often evolve as states evaluate how economic nexus rules affect businesses and tax administration.
States may update nexus laws for several reasons.
- Simplifying compliance requirements
- Reducing burdens for small businesses
- Improving enforcement of sales tax collection
- Aligning with tax policies adopted by other states
These changes typically involve adjustments to nexus thresholds or measurement periods. Businesses operating nationally should stay informed about regulatory updates that may affect their tax obligations.
To review current nexus thresholds across states, see: Economic Nexus by State.
States That Removed Transaction Thresholds
One of the most common changes to economic nexus laws has been the removal of transaction thresholds. Several states originally required businesses to register for sales tax once they exceeded
$100000 in annual sales
or
200 transactions within the state
However, some states concluded that transaction thresholds created unnecessary complexity for businesses processing large volumes of small orders.
As a result, many jurisdictions removed the transaction rule and now rely solely on revenue thresholds. A detailed explanation of these changes is available in See: States Without Transaction Thresholds.
Changes to Revenue Thresholds
In addition to removing transaction thresholds, some states have updated revenue limits used to determine nexus.
While the most common threshold remains $100000 in annual sales, a few states use higher thresholds such as $500000. These variations reflect differences in state tax policy and enforcement priorities.
Businesses selling products or services across state lines should monitor revenue levels carefully to determine when nexus obligations arise.
You can estimate nexus thresholds using the economic nexus calculator.
Changes to Measurement Periods
Another area where states have updated nexus rules is the measurement period used to determine sales activity.
Measurement periods may include
- The current calendar year
- The previous calendar year
- Rolling twelve month periods
- Previous four quarter periods
Changes to measurement periods may affect how businesses calculate nexus thresholds. Companies that track revenue and transactions by state can identify when thresholds are approaching.
Why Monitoring Nexus Changes Is Important
Sales tax compliance requires businesses to stay informed about regulatory updates across multiple jurisdictions. Companies that monitor nexus rule changes can adjust compliance strategies as regulations evolve.
Businesses that fail to track these changes may unknowingly create nexus obligations in states where laws have been updated.
Tracking revenue by state and reviewing threshold updates helps businesses remain compliant as their sales expand nationally.
Businesses that discover nexus exposure after regulatory changes may need to estimate historical liabilities.
