What Forms Are Required for an IRS Offer in Compromise? (Oklahoma CPA Guide)

Filing an IRS Offer in Compromise (OIC) can be one of the most powerful ways to settle your tax debt for less — but it’s also one of the most paperwork-heavy.

Missing even one form can cause delays, rejection, or worse: IRS collections continuing while you wait.

At Boulanger CPA and Consulting PC, we help Oklahoma clients file successful, complete Offer in Compromise packages the first time. In this guide, we’ll show you which forms are required, how they work, and what the IRS expects in 2025.

The 3 Required Forms for Most OIC Submissions

You’ll typically need the following:

1. IRS Form 433-A (OIC)

This is the financial disclosure form for individuals, including self-employed taxpayers. It shows:

• Income and expenses
• Assets and debts
• Equity in vehicles, property, bank accounts, and more

Learn more in our full IRS Form 433-A (OIC) guide for Oklahoma taxpayers.

2. IRS Form 656

This is the actual offer form where you propose a settlement amount.

It includes:

• Tax periods and types you’re settling
• Payment method (lump sum or short-term plan)
• Whether you qualify for the Low-Income Certification

Most offers will not be considered without Form 656 signed and submitted with payment.

3. $205 Application Fee + Initial Payment

Unless you qualify for Low-Income Certification (based on household size and income), you’ll need to send:

• $205 nonrefundable application fee
• 20% down if using lump sum method
• First monthly payment if proposing a short-term plan

Use our OIC Calculator to estimate what your payment should look like.

Additional Forms You May Need (Depending on Your Case)

▪️ IRS Form 433-B (OIC)

Used if you are submitting an offer on behalf of a business.

▪️ IRS Form 2848 (Power of Attorney)

Required if you want a CPA or tax professional to represent you.

At Boulanger CPA, we file this the same day we take your case.

▪️ IRS Form 656-L (Doubt as to Liability Offer)

Used only if you disagree with the underlying tax debt (not based on ability to pay).

This is rare and must be handled carefully.

Common Mistakes That Cause OIC Delays

Even when the right forms are submitted, the most common mistakes we see are:

• Missing signatures
• Outdated financial info (older than 6 months)
• Omitting required attachments (bank statements, pay stubs, etc.)
• Failing to send initial payment or application fee
• Using the wrong forms (e.g., 433-A instead of 433-A (OIC))

Let us help you get it right the first time with a CPA-reviewed OIC submission.
