Cleaning Up Sales Tax Across 9 States
A multi-channel e-commerce brand had unknowingly created nexus in nine states. We got them compliant without penalties, before the exposure was ever flagged by a state authority.
Growth That Outran Sales Tax Registration
Northline Home Goods sold across their own Shopify store, Amazon, and two other marketplaces, and had grown quickly through paid advertising and marketplace fulfillment programs. Nobody on the team had tracked where that growth was creating economic nexus for sales tax purposes.
By the time Northline came to Ledger for a routine bookkeeping engagement, the business had unknowingly crossed economic nexus thresholds in nine states — with zero sales tax registrations or filings in any of them.
Where the Business Stood

The nexus exposure surfaced during Ledger's onboarding review, not through a state notice — which gave Northline the chance to get ahead of it. The priority became resolving the exposure quietly and correctly before any state initiated contact.
What We Did
Mapped Nexus by State and Channel
We analyzed sales by state and channel to determine exactly where and when nexus thresholds were crossed.
Pursued Voluntary Disclosure Agreements
We filed voluntary disclosure agreements in eligible states to limit lookback periods and avoid penalties.
Registered and Filed Going Forward
We registered Northline in all nine states and set up ongoing filing for future periods.
Automated Ongoing Nexus Monitoring
We put monitoring in place so any future nexus threshold is caught before it becomes a liability.
How We Supported the Business
What Changed

Northline resolved all nine states' exposure through voluntary disclosure agreements, avoiding penalties entirely and limiting lookback liability. Ongoing nexus monitoring now means the business won't be caught off guard by growth into new states again.
What Other Business Owners Can Learn
Economic nexus can be created by marketplace and advertising growth long before anyone notices, especially across multiple channels.
Getting ahead of a state notice through voluntary disclosure is almost always better than waiting for one to arrive.
Nexus exposure needs ongoing monitoring, not a one-time check — thresholds can be crossed again as sales grow.
“We had no idea we were exposed in nine states until Ledger caught it. Getting ahead of that before a state did was worth more than we can measure.”
