Full Definition

IRS Form 433-B is the Collection Information Statement for Businesses, the financial disclosure document the IRS requires businesses to complete during active collection proceedings — particularly when requesting an installment agreement, OIC, or currently not collectible status. Form 433-B requires disclosure of: all business bank accounts (with account numbers), business assets (equipment, inventory, real property, accounts receivable), business income (gross receipts and all sources), business expenses (all ordinary and necessary expenses), and any owners or officers with equity interests. The IRS uses Form 433-B to calculate the business’s Reasonable Collection Potential and ability to pay. IRS Revenue Officers review Form 433-B in detail and will cross-reference the information against tax transcripts, credit reports, and public records. Businesses should have tax representation before completing Form 433-B — incorrect, incomplete, or misleading information can constitute a federal crime.
