Taxpayers mix up the reduced amount with the full tax debt

→ Verify the figure on the IRS approval notice

Fee amount

The fee varies by offer size

→ Check the current fee schedule before attaching payment

Mailing address

Some taxpayers use the generic IRS address

→ Use the address printed on the specific notice

Installment length

IRS may limit the number of months

→ Confirm the maximum term allowed in the notice

Signature requirement

Joint filers think one signature suffices

→ Both spouses must sign if jointly liable
