Retroactive Pay
I'm pretty sure I know the answer to the following question but I would just like some clarification. I was wondering which tax year retroactive pay would apply to. I began a job beginning November of 2016 but didn't receive pay for November and December until February of 2017. I also didn't receive a W2 for 2016 (which I think answers my question) but did for 2017 (which I cannot find of course). So I was wondering, does the income for work from 2016 that was received in 2017 apply to the tax year 2017 (when it was received) or 2016 (when it was earned)?
