My employer is getting my W2 to me late. Should I just submit my taxes with a substitute w2?

[opopi123]

I called my old employer a week ago but they are taking their time getting my w2 to me. They initially sent my W2 my mail but I never got it because they didn't update my new address in their systems. I called them and they said there is no guaranteed they can get it to be today. Should I just submit my taxes with a substitute W2 and estimate my wages?

The substitute W-2 has to be mailed and that delays you refund for a long time.
