We strongly recommend against using your last check stub to file your tax return. You need information from your W-2 that is not included on your check stub. You may miss out on credits, etc. for which you qualify. In addition, if the information filed does not match the W-2, you will have to file an amended return.
E-file does not begin until late January or early February and W-2's are required to be out by January 31st.
