Last year one of my friend told me that he will file my tax online so i gave all my papers to him but what happend was he tried to do it on the last day and he said due to some computer pblm he could not file it online. so what i did was i mailed (postal mail) it next day which was already after a cut off date. i did not get any response from IRS. I dont even know if my tax got filed, my concern is will it affect me if it was not filed. I wanted to know that before i file my tax this yr.
