You may be able to add the balance due for last year to your current payment plan without defaulting, here are some things to keep in mind:
1.Get a hold of the IRS by phone. You will need to ask if the new balance can be added to your existing installment agreement. You may also be able to call the number on your recent IRS statement.
2.If you prefer, you can submit a new Form 9465, Installment agreement request, and indicate you would like to add the new balance to your current agreement. This can be done online, or through the mail.
3.It is imperative to address the new balance as soon as possible. Not taking action could lead to future penalties and interest.
