B) Your employer benefits documentation
Explanation:
Your employer benefits documentation has little to do with your taxes as it is not a part of the tax rebate schemes.
Supplement income is very much a part of taxable income, so it has to be produced.
The W 2 form is the primary taxation form one receives from the IRS which is to be filled while filing for taxes.
Routing and bank account details need also be provided to track all the income generated through supplementary and main sources of income.
