I filed my taxes through H&R block in 2004 owing a few thousand dollars. I sent a check for the amount due but the check was never cashed by the IRS. I have filed my return every year since almost always getting money back. They have never said anything about the 2004 year. It has now been 10 years since then and still haven't received anything from them about 2004.

This year I owe a couple thousand and want to apply for the online payment plan. Will this be a red flag and cause the IRS to notice my 2004 taxes not being paid. Or should I not worry about it because the statute of limitation on collection of the return has been reached.

The reason they did not cash my check was due to my parents claiming me as a dependent even though I wasn't. My parents refiled their taxes not having me as a dependent leaving my tax return being true but they never cashed my check. I did not receive anything asking me to re-file.

Advice would be appreciated.

Thanks,
