Wash sales + restricted stock in USA: grant date or vesting date?
For restricted stock, I think the vesting date meets the requirements of the second wash sale trigger from IRS Pub 550: Wash Sales: Acquire substantially identical stock or securities in a fully taxable trade I base this on these two quotes from IRS Pub 525: Restricted Property: any income from the property, or the right to use the property, is included in your income as additional compensation in the year you receive the income or have the right to use the property. - Until the property becomes substantially vested, it is owned by the person who makes the transfer to you, usually your employer.  So on the vest date: The transfer is taxable Ownership is transferred to you That seems close enough to "a fully taxable trade" for me.  Maybe this changes if you pay the tax on the stock on the grant date. See Pub 525: Restricted Property: Choosing to include in income for year of transfer. Obviously, if this is important you should consult your tax advisor.  Technicalities aside, I don't think it passes the sniff test. You're getting salable shares when the restricted stock vests. If you're selling other shares at a loss within 30 days of the vesting date, that smells like a wash sale to me.
