Welcome to Just Answer. I am here to help you resolve your tax and finance concerns. Please feel free to ask anytime you need extra help.
The credit you have on file is probably due to payments already made towards the obligation. If you have access to some information it will certainly help. If the following, or any of them are available, please let me know and I will assist you.
941 forms - These are filed quarterly and provide wage totals for the quarter
State returns - These will reflect wages (sometimes per individual) and can be used to replace the 941 information in the event the 941 forms are no longer available.
W-2 forms - These will provide the wages on an individual basis.
Any wage printouts you may have.
Once you have identified what you do possess and get back to me we will be able to proceed.
