Who This Is For

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.

Two Ways to Assess Nexus

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

$495

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

Starting at $1,000

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.

Stay Current

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.

Transparent Flat-Fee Pricing

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.

Clarifications

Sales Tax Questions, Answered

What is economic nexus?
After the 2018 Wayfair decision, states can require you to collect sales tax once your sales into that state pass a dollar or transaction threshold, even if you have no physical presence there. We determine where you have crossed those lines.
I sell on Amazon. Do I still owe sales tax?
Marketplace facilitators like Amazon often collect and remit tax on marketplace sales for you, but your own website and other channels can still create obligations. We review your full sales picture.
How do I know which states I owe in?
We run a nexus analysis across your sales by state to identify exactly where you are required to register and collect.
I have not been collecting. Am I in trouble?
There may be back liability, but it is manageable. Where it helps, we use state voluntary-disclosure programs to limit penalties and look-back periods. We assess your exposure first.
Can you automate this?
Yes. We set up tools like Shopify tax, Avalara, or TaxJar so the correct tax is collected and your filings stay on schedule.
How much does it cost?
You get one flat fee, quoted after an introductory consultation, based on the number of states and the complexity of your sales, before any work begins.
