Do I need to report my online purchases and pay taxes on them?

Yes, you generally need to report and pay taxes on your online purchases in Washington state. If you purchase goods or services from a retailer that does not collect Washington sales tax, you are required to report and remit the use tax. Use tax is essentially the equivalent of sales tax but applies to out-of-state purchases. You are responsible for reporting and paying the use tax directly to the Department of Revenue. Failure to do so may result in penalties and interest. However, some exemptions and thresholds may apply, so it's advisable to consult the Department of Revenue's guidelines or consult a tax professional for specific circumstances. Reporting and paying taxes on online purchases ensures fairness and upholds the tax obligations of Washington residents.
