Sales-tax nexus and registration depend on the state, the seller's activity and the applicable rules. Bookkeeping should provide the evidence for that review, not turn one sales total into a nationwide tax conclusion. This guide covers records and a California example; it is not a fifty-state threshold table or tax advice.
Which sales data should you keep?
Retain order date, destination, channel, gross sale, refunds, tax collected and settlement reference. Keep the original exports as well as the accounting entries. Your tax adviser may need information beyond a bank deposit or net marketplace payout to determine the relevant sales measure and period.
Reconcile channel totals to recorded sales and explain timing, cancellations and refunds. Avoid assuming that an accounting revenue total is automatically the amount used for every state's nexus calculation.
Why is one threshold not enough?
Economic thresholds, measurement periods, included sales and commencement rules vary. Physical activity can raise separate questions. Record where inventory, employees and other business activity are located and give the facts to the adviser rather than treating low sales as proof that no obligation exists.
California illustrates the need for detail. CDTFA's marketplace guide describes economic nexus when covered California merchandise sales exceed $500,000 in the preceding or current calendar year, including marketplace sales. It also describes an exception to registration when all such sales are facilitated by qualifying marketplace facilitators. Read the full conditions rather than applying the dollar figure alone.
Does marketplace collection settle everything?
No. Keep evidence showing which marketplace collected tax and which transactions it covered. Direct sales and other activities may require separate analysis. The California example shows why counted sales, tax collection and registration should not be treated as the same question.
Do not count tax the marketplace handled as money your business collected merely because it appears in a report. Map the settlement fields and retain the marketplace's statement. Any remaining seller obligation needs the applicable jurisdiction's review.
How should collected tax be reconciled?
For tax collected on behalf of an authority and payable by the seller, track the liability separately from sales revenue. Reconcile the opening balance, collections, refunds, adjustments and remittances to the relevant reports. Investigate differences instead of clearing the account to zero without support.
Ask the adviser to approve mappings for unusual fees, discounts, exempt transactions and refunds. A software tax setting or integration does not establish that registration, collection and returns are correct.
What if an earlier period is unclear?
Preserve the history and identify the states, channels and dates involved. Ask a qualified sales-tax adviser to assess obligations, effective dates and any corrective options before changing registrations or making filings. A present-day registration should not be described as resolving every earlier period.
Bookkeeping cleanup can reconstruct records where evidence is available. It cannot guarantee the absence of tax, interest, penalties or other exposure. Document missing exports and unresolved questions rather than filling gaps with unsupported totals.
What is Daxable's role?
Daxable retains this existing article as recordkeeping guidance. It does not provide sales-tax nexus determinations, registration advice or tax filing. Any bookkeeping assistance must be separately scoped, with the relevant decisions and return preparation left to your qualified tax professional.
Use the official state guidance for each jurisdiction in scope. This article deliberately does not supply a universal transaction-count rule, registration date or marketplace exemption.

Frequently Asked Questions
Does marketplace tax collection remove every registration obligation?
Not necessarily. Registration and collection rules depend on the state and your activities, including direct sales. Keep marketplace evidence and obtain a jurisdiction-specific determination.
Can I use one sales threshold for every state?
No. The amount, measurement period, included sales and physical-presence rules differ. Review the current official rules for each state in scope.
What records help a sales-tax adviser?
Order and destination data, channel totals, refunds, marketplace tax statements, direct collections, remittances and records of physical activity help support the review.
Does Daxable determine nexus or file sales-tax returns?
No. Daxable's bookkeeping support does not include tax determinations, registration advice or tax filing.
