Key Tax Group promised me if I would send their fee of $1800. my tax payment would be less. I sent the money in monthly payments until the total amount was paid. Key Tax Group then set up a monthly payment plan with IRS for my full tax debt. I not only lost the $1800. fee, but am paying the full tax debt, plus interest, and penalty. Key Tax Group delayed for over 6 mo. adding additional interest. I asked for a partial refuld because the promise of a lower tax bill was not met and was denied... Be warned they will promise you anything to get their fee and then you get nothing in return but a higher tax bill in fines and interest..
