The IRS will let you pay off your federal tax debt in monthly
payments through an installment agreement.
If you haven't filed yet, step through the File section of TurboTax until you reach
the screen How do you want to pay your
federal taxes? Select the installment
payment plan option, click Continue,
and follow the onscreen instructions.
If you already filed, or you're unable to find this
option in TurboTax, you can apply for a payment plan at the IRS
Payment Plans and Installment Agreements web
page (make sure you've filed your return before applying through their site).
State Payment Plans
Most states offer some kind of installment payment plan as well,
although the procedure varies from state to state.
The easiest way to obtain the info you need is to simply
search the internet using the phrase <state> tax payment plan (for
example, New Jersey
tax payment plan or Illinois tax payment plan). You can also try contacting your state Department
of Revenue for details.
