Nowadays, social media has become a real venture, thanks to the creator economy. You can make money from sponsored posts, subscriptions, affiliate sales, digital products, and branded merchandise for California TikTokers, YouTubers, streamers, and influencers. If customers, sponsors, and fulfillment companies are in different states, however, it can become complicated to determine where the income is taxable.

Income from a brand partnership typically is income from a trade or business when such a business is kept up by the creator. In general, taxpayers in California are taxed based on income earned anywhere in the world. California may still have income from sources within the state even if the income is from nonresidents, such as the income from services performed in California.
For the creators, the place where the promotion is done can be important. California-source income may be earned by a creator making a sponsored video in a California studio, even if the customer and sponsors are outside of California. Get an expert (like a tax lawyer in San Francisco) who can guide you in tax matters.
Creators can sell digital products, such as ebooks, downloadable art, courses, memberships, templates, and more. The definition and treatment of digital products in California is rapidly evolving.
California will generally impose sales and use tax on taxable retail sales commencing on January 1, 2027, on certain digital products transferred electronically or used remotely, including qualified digital products.
Starting January 1, 2027, sales and use tax will be generally imposed on certain taxable retail sales of qualified digital products of all types transferred electronically or accessed remotely (“qualifying digital products”). The new rules also create rules at a specific level to determine the place of sale. The address of the purchaser is generally the address if you are selling or purchasing remotely.
Creators should therefore be careful to differentiate between the income-tax source and sales-tax obligations. They’re different topics.
If you are selling T-shirts, hats, stickers, or other tangible items, there is an additional set of requirements. California does not consider internet sales exempt when the orders are made through TikTok, Instagram, Shopify, or any other platform. The tax treatment will vary based on the transaction, the location of the merchandise, its delivery location, and whether a marketplace facilitator is liable for collecting tax for the transaction.
This can be made more difficult with drop shipping. A creator can take an order and have the product shipped directly to the customer by the supplier or fulfillment. California sales or use tax may be imposed on merchandise shipped to customers in California. Collection responsibilities may be shifted to the marketplace facilitator and inventory may be placed at a California fulfillment center, which can result in California registration obligations.
Generally, California sales tax is not levied on sales made directly outside of California, provided the transaction fulfills the requirements for out-of-state delivery in California. Hiring a professional (similar to a San Jose tax attorney) will surely help you in the long run.
Stay organized from the start of your business:
California creators don’t need to take this as a “tax-free” or “presentation-free” statement. Income-tax sourcing, sales-tax, registration, and recordkeeping rules may vary based on the type of sponsored content, digital product, or merchandise. An understanding of where services are rendered, where customers are, and where products move can decrease expensive compliance surprises.
