My employer is based in Australia. These shares were granted in 2014 and I paid no taxes at that time. When I sold all of these shares in 2017 at the time of vesting the proceeds were direct deposited to my US account. There was no tax withholding. I made a 1040es estimated tax payment to the IRS at that time to cover what I though was the estimated amount of tax on that income.
My W2 does not reflect this income. The Australia brokerage who manages the stock program and made the payment to me did not provide me with a 1099.
How do I report this income? Do I need to report it? Did my employer make a mistake my not including this income on my W2? What if the Australian brokerage did not report it to my employer?
