WAIT for all of your W-2's. Do not use a pay stub. It will not match your W-2. If you e-file before you have it all just to file a couple of days earlier--since employers issue W-2's by January 31-- you might end up having to amend an incorrect tax return. It takes about 4 months for the IRS to process an amended return.
