How can you ensure documents that were mailed were received?

[xmasbaby0 · Accepted solution]

Next time you mail in tax documents use a mailing service that will track it like UPS or certified mail then you will know it was received.  For now, if you did not do that, you have to wait about 4 weeks to see if the IRS site is showing information about your mailed return.
