IRS Form 433-B – IRS Forms, Instructions, Pubs 2026 – If your business owes back taxes and the IRS is pursuing collection, you’ll likely need to submit IRS Form 433-B, officially titled the Collection Information Statement for Businesses. This form provides the IRS with a detailed snapshot of your company’s finances to determine payment options such as installment agreements, temporary delays in collection, or currently not collectible (CNC) status.
In this comprehensive guide, you’ll learn exactly what IRS Form 433-B is, who must complete it, when to use it, how to fill it out step by step (with tips from official IRS Publication 5059), required documents, common mistakes to avoid, and key differences from the newer Form 433-B (OIC) used for Offers in Compromise.

What Is IRS Form 433-B?
Form 433-B is the IRS’s primary tool for gathering current financial data from businesses with outstanding tax liabilities. The IRS uses the information to calculate your business’s ability to pay and to decide on the most appropriate collection action.
Important note on versions (as of February 2026):
- Standard Form 433-B (Rev. 2-2019): Used for most collection situations (installment agreements, CNC status, etc.).
- Form 433-B (OIC) (Rev. 4-2025): A specialized version required only when submitting an Offer in Compromise (Form 656) to settle the debt for less than owed. It includes extra sections for asset valuation adjustments (e.g., 80% of fair market value for real estate/vehicles) and a built-in “Minimum Offer Amount” calculation.
Sole proprietorships do not use Form 433-B — they file Form 433-A instead.
Who Must Complete IRS Form 433-B?
The following business entities must file Form 433-B when requested by the IRS:
- Partnerships
- Corporations (including S Corporations)
- Exempt organizations
- Limited Liability Companies (LLCs) classified as corporations
- Other LLCs (with number of members noted)
A partner, corporate officer, or LLC member authorized to bind the business must sign the form under penalties of perjury.
When Is Form 433-B Required?
The IRS typically requests this form when your business:
- Requests an installment agreement (payment plan)
- Seeks a temporary delay in collection or CNC status
- Faces enforced collection (levies, liens)
- Applies for an Offer in Compromise (use the OIC version)
Failing to provide complete and accurate information can delay resolution or result in rejection of your request.
Step-by-Step Guide: How to Fill Out IRS Form 433-B (Standard Version)?

Key definitions (Pub 5059):
- Fair Market Value = amount you could sell the asset for today.
- Do not list bank loans under bank accounts.

Expense lines (allowable business expenses only):
- Materials purchased, inventory purchased, wages/salaries, rent, supplies, utilities/telephone, vehicle expenses, repairs/maintenance, insurance, current taxes, other expenses.
Calculate Net Income (Income minus Expenses). Lines 47–49 are for IRS use only.
Important exclusions:
- Do not include non-cash expenses (depreciation, bad debts, depletion).
- Interest cannot be deducted separately if already included in installment payments.
Required Supporting Documents and Verification
After review, the IRS will request verification. Prepare:

- Loan/lease statements
- Vehicle titles/registration
- Real estate appraisals or tax assessments

- Initial and date any changes after signing.
Avoid:
- Leaving blanks (use “N/A” or attach explanations).
- Omitting foreign assets, accounts, or personnel.
- Including non-cash expenses in Section 5.
- Duplicating secured debts (e.g., listing equipment loan in both equipment and liabilities sections).
- Submitting without required attachments.
Pro Tip: The IRS compares your Form 433-B against Collection Financial Standards. Overstating expenses or understating assets can lead to denied relief.
What Happens After You Submit Form 433-B?
- IRS reviews the form (may take weeks).
- You receive a request for verification documents.
- IRS calculates your “ability to pay” and proposes a resolution (installment agreement, CNC, etc.).
- If approved, collections may be paused or restructured.
Form 433-B vs. Form 433-B (OIC): Key Differences
Use the OIC version (April 2025) only with Form 656. It features:
- Asset equity calculations (often 80% of FMV for real estate/vehicles)
- Digital asset reporting
- Monthly income/expense averages leading to a “Remaining Monthly Income” figure
- Built-in multiplier (×12 or ×24) to determine future income component of the minimum offer
- Extra disclosures on bankruptcy, litigation, asset transfers (past 3/10 years), and foreign holdings
For OIC applications, also review the Offer in Compromise Booklet (Form 656-B).
