Use Tax Collection Requirements Based on Sales into California Due to the Wayfair Decision

The new use tax collection requirement for remote sellers will apply to taxable sales of tangible personal property to California consumers on and after April 1, 2019, and is not otherwise retroactive. Retailers that exceed the $500,000 sales threshold in the preceding or current calendar year are now required to register with CDTFA to collect the California use tax even if they were not previously required to register. These retailers include retailers that sell tangible goods for delivery into California through the Internet, mail-order catalogs, telephone, or any other means.

This guide contains information about the Wayfair decision and AB 147 and describes their effect on the requirements to collect California state, local and district use tax, and on the collection of special taxes and fees.
