How long after nexus ceases must a remote seller collect California sales tax?

A remote retailer must remain registered with the CDTFA and continue to collect state use tax throughout any calendar year its sales in California exceed the $500,000 economic nexus threshold described above, “and during the following calendar year.”

A remote retailer is not required to remain registered on January 1 of any subsequent year if, during the preceding calendar year, its sales (and sales by all related persons) of tangible personal property in the state didn’t exceed the $500,000 economic nexus threshold.

For example, a remote retailer whose California sales exceed the $500,000 economic nexus threshold in 2020 but not in 2021 or 2022 is required to register with the CDTFA as soon as its sales cross the economic nexus threshold in 2020 and collect and remit California state use tax through December 31, 2021.

As of January 1, 2022, the remote retailer is no longer required to maintain its Certificate of Registration and collect California use tax. However, it may voluntarily maintain its certificate with the CDTFA and continue collecting and remitting state use tax.

Effective April 25, 2019, a remote retailer must collect district use tax in California if its sales in the state of California exceed the $500,000 economic nexus threshold. As with state use tax, the remote retailer must continue to collect district use tax for the remainder of that calendar year, as well as during the following calendar year.

The CDTFA provides more details and examples of how a retailer can establish nexus and how trailing nexus applies in California Code of Regulations, Title 18, Section 1684, Collection of Use Tax by Retailers.
