Sales Tax and Economic Nexus Compliance
Selling on Shopify, Amazon, or across state lines? A licensed CPA figures out where you have created sales-tax nexus, gets you registered, and sets up collection, so you are compliant in the states where you have obligations and less likely to face a surprise assessment.
Built for Multi-Channel and Online Sellers
If any of these sound familiar, this service was built for your situation.
You sell across channels
Shopify, Amazon, Etsy, and your own site, each with its own sales-tax wrinkles.
You crossed a threshold
Your sales into a state passed its economic-nexus limit, creating an obligation you may not know about.
You do not know where you owe
You sell nationwide and have no clear picture of which states expect a return.
You got a state notice
A state you never registered in says you owe sales tax.
You are not collecting
You worry about building up back liability the longer it goes unaddressed.
You want it automated
You would rather have sales tax handled and off your plate for good.
Sales Tax, Sorted State by State
You get a licensed professional who determines your obligations and sets up clean compliance.
Nexus determined
We analyze your sales to find every state where you have crossed an economic or physical nexus threshold.
Registrations handled
We register your business for sales tax in the states where you are required to collect.
Collection automated
We set up your platforms and tax tools so the right tax is collected going forward.
Flat fee, quoted upfront
One fixed price after an introductory consultation. No hourly meter, and you approve the number before any work starts.
Everything Your Sales-Tax Compliance Needs
A complete approach to getting and staying compliant across states.
Nexus Screening or a Comprehensive Study
Start with a focused screening, or go deeper with a full exposure study. We help you pick the right one.
Sales Tax Nexus Screening
A fixed-fee, focused look at one business and one tax type: review of your completed intake questionnaire and summarized sales by state, threshold screening, identification of states that need a closer look, a findings meeting, and a brief written findings summary. The $495 is credited toward a voluntary-disclosure engagement begun within 60 days.
This is a screening, not a complete nexus study. It does not include detailed product-taxability research, transaction-level testing, historical exposure calculations, prior-period returns, registration, VDA representation, income or franchise tax nexus, physical-presence legal analysis, a formal written tax opinion, or more than the stated data scope.
Comprehensive Nexus and Exposure Study
A deeper review that can cover sales-tax nexus, physical presence, economic nexus, marketplace-facilitator activity, employee or contractor activity, state-by-state threshold analysis, exposure-period identification, registration recommendations, VDA considerations, and written findings.
Custom pricing applies for multiple tax types, a significant state count, transaction-level review, uncertain taxability, complex physical-presence facts, or material historical exposure.
Ongoing Sales-Tax Filing and Compliance
Once you are registered, we can manage the recurring filings so nothing slips.
Filing management
State registration coordination, monthly and quarterly filings, and zero returns where required.
Calendar and payments
Filing-calendar management, payment coordination, and account maintenance. You review, approve, and fund the payments.
Monitoring and review
Notice monitoring, marketplace and direct-sales reconciliation where included, and an annual nexus review. Priced as a custom monthly fixed fee.
You Know the Cost Before Any Work Begins
Sales-tax work is priced by the number of states and the complexity of your sales, confirmed as one flat fee after an introductory consultation, before any work begins. See the Fees page for how flat-fee pricing works.
