1. I want to pay tax by credit card, so I don't think I need to attach Form 1040-V Payment Voucher
for Individuals ? Can I pay later via IRS website?
2. Do I need to attach my W2 copy in both state and federal return?
3. I don't think I need to attach the state return to IRS?
4. Do I need to attach my federal return to state return?
5. There is no instruction where I can mile my tax return to California, can anyone please confirm.
