IRS Form 433: What You Need To Know

Form 433 is the IRS Collection Information Statement, a financial disclosure of your income, expenses, assets, and debts. The IRS uses it to decide how much you can realistically pay toward a tax balance. It backs up requests for installment agreements, offers in compromise, and currently not collectible status.

The 433-F is the short statement most individuals use in general collection cases. The 433-A is the long version for individuals and the self-employed with more complex finances, often tied to a revenue officer or an offer in compromise. The 433-B is for businesses such as corporations, partnerships, and LLCs.

People who owe the IRS and cannot pay in full, and who do not qualify for a simple streamlined installment agreement, are typically asked to file a 433. It is also required when you apply for an offer in compromise or request currently not collectible status, because the IRS needs to verify your ability to pay.

The 433-F is the most common individual Collection Information Statement. The IRS uses it to evaluate income, allowable living expenses, and assets, usually to set up an installment agreement or to assess hardship. It is shorter than the 433-A but still drives the decision on what you will be asked to pay.

The plain 433-A is a general collection statement. The 433-A (OIC) is a version used specifically when you apply for an offer in compromise, and it walks through the calculation of your reasonable collection potential, the figure the IRS uses to decide whether to accept your offer and for how much.

The IRS subtracts your allowable living expenses, based partly on national and local standards, from your monthly income, and treats what remains as your ability to pay. It also considers the equity in your assets. That calculation determines whether you get an installment agreement, an offer, or a collection pause.

Expect to gather recent pay stubs or profit figures, bank statements, and bills for expenses such as housing, utilities, transportation, and health care. The IRS may ask you to substantiate what you report, so having documentation ready supports your numbers and reduces back-and-forth or rejection.

Allowable expenses are the living costs the IRS lets you subtract from income when calculating what you can pay, including housing and utilities, food and clothing, transportation, health care, and certain taxes. Many are subject to national or local standard caps, so claiming the ones you are entitled to is important.

Errors can be costly. Understating income can lead to rejection or a request for more detail, while overstating your ability to pay, or omitting allowable expenses, can lock you into a payment you cannot sustain. Because the numbers drive the outcome, accuracy and documentation matter more than explanations.

You can complete it yourself, and many people do for a straightforward 433-F. Complex finances, self-employment, a revenue officer, or an offer in compromise are the situations where people most often bring in a licensed tax professional, because the calculation is technical and the stakes on the monthly figure are high.
