Where do I send 1099 misc copy 1 for the Washington state?

In Washington state, you do not need to send a copy of the 1099-MISC form to the state, as it does not have a personal income tax. However, if you're required to file with the IRS, make sure to send Copy A to the IRS and provide the appropriate copies to the recipient. Always check for any updates or specific requirements from the Washington State Department of Revenue or the IRS.
