Form 656 Instructions & Fax Guide 2026

What Is Form 656?

Form 656, Offer in Compromise, allows taxpayers to settle their tax debt with the IRS for less than the full amount owed. This program is designed for taxpayers who genuinely cannot pay their full tax liability. The IRS considers your ability to pay, income, expenses, and asset equity when evaluating your offer.

Why You Might Need Form 656

You may qualify for an Offer in Compromise if you have significant tax debt you cannot pay. Common situations include:

• •You owe a substantial tax balance that you cannot fully pay
• •Your income and assets are insufficient to cover the tax debt
• •You've experienced financial hardship (job loss, medical emergency, etc.)
• •The IRS collection statute is expiring and they may accept a reduced amount
• •You dispute the tax liability (doubt as to liability)
