[Event] MetLife & TurboTax Present: The Ask Us Anything Forum

I'm not sure if you can see the previous thread but I asked about ways to estimate our tax burden because we have owed a lot. One of the suggestions was making quarterly payments to the IRS or increasing our federal withholdings. Could we put the amounts into the HRA account and increase our 401K contributions dollar per dollar to not owe? So instead of paying $2500 each quarter could I split that quarterly $2500 between our 401K's and HRA accounts?
