Don’t panic. If you cannot pay the full amount of taxes you owe, you should still file your return by the deadline and pay as much as you can to avoid penalties and interest.
You also should contact the IRS to discuss your payment options at 800-829-1040. The agency may be able to provide some relief such as a short-term extension to pay, an installment agreement or an offer in compromise, or by temporarily delaying collection by reporting your account as currently not collectible until you are able to pay.
In some cases, the agency may be able to waive penalties. However, the agency is unable to waive interest charges which accrue on unpaid tax bills.
