How should I report earning from Apple App Store (from iTunes Connect) in Washington state?
If you're waiting for Apple to send you a 1099 for the 2008 tax season, well, you shouldn't be. App Store payments are not reported to the IRS and you will not be receiving a 1099 in the mail from anyone. App Store payments are treated as sales commissions rather than royalties, according to the iTunes Royalty department of Apple. You are responsible for reporting your earnings and filing your own payments for any sums you have earned from App Store.   – https://arstechnica.com/apple/2009/01/app-store-lessons-taxes-and-app-store-earnings The closest thing to sales commissions in WA state seems to be Service and Other Activities described at  http://dor.wa.gov/content/FileAndPayTaxes/BeforeIFile/Def_TxClassBandO.aspx#0004. When you dig a little deeper into the tax code, WAC 458-20-224 (Service and other business activities) includes: (4) Persons engaged in any business activity, other than or in addition to those for which a specific rate is provided in chapter 82.04 RCW, are taxable under the service and other business activities classification upon gross income from such business.   - http://apps.leg.wa.gov/wac/default.aspx?cite=458-20-224 I am not a lawyer or accountant, so caveat emptor.
