If you are mailing your tax return instead of e-filing, be aware that it is taking a very long time for the IRS to process mailed returns---it will take months. Use a mailing service that will track your mailed return so that you will know the IRS received it.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
