Merchant of Record keeps more at this revenue level
Merchant of Record fee assumption: 5% of gross. Tax collection and remittance are handled by the provider; the tax liability card shows what you would owe under the self-managed model. FX friction uses a fixed 2.2% planning assumption.
Runway assumes a flat monthly run-rate. Seasonal spikes, refunds and marketplace-facilitator sales can move the real registration date.

How we calculate →The rule, unpacked
What the Sales tax threshold actually measures
A remote seller generally has economic nexus when total combined sales of tangible personal property for delivery into California exceed USD 500,000 in the prior or current calendar year.
Measurement basis
Prior or current calendar year sales
The USD 500,000 test counts total sales, not only taxable sales.
Registration timing
30-day window
Confirm the effective date and any local agent requirements with California Department of Tax and Fee Administration.
Who must register
Remote sellers whose combined sales of tangible personal property delivered into California exceed USD 500,000 in the prior or current calendar year.
Exceptions & edge cases
Marketplace facilitators may collect on behalf of sellers. Local district taxes and product-specific exemptions can change the effective rate.
Conditions to check
- The USD 500,000 test counts total sales, not only taxable sales.
- Marketplace facilitator rules can shift collection obligations.
Rate context
The calculator uses a planning rate, not every rate
District taxes can raise the combined rate above 7.25%; use your actual location rate.
The estimate is useful for sizing exposure, not for preparing a return. Product-specific rates, exemptions, reverse-charge rules and place-of-supply tests can change the amount you actually owe.
