Overview
Form 433-F (Collection Information Statement) asks for a snapshot of your financial life so the IRS can assess whether you can pay a tax debt now, over time, or not at all. The IRS uses the data to set monthly payment amounts, decide if a taxpayer qualifies as Currently Not Collectible (CNC), and to evaluate collection alternatives. (See IRS: About Form 433-F: https://www.irs.gov/forms-pubs/about-form-433-f)
When to use Form 433-F
- You’ve received a collection notice and the IRS requests a financial statement.
- You want an installment agreement but owe more than the amounts allowed for streamlined online setup.
- You seek CNC status or need the IRS to re-evaluate an existing agreement after a major income change.
What the form collects
- Monthly and annual income (pay stubs, business receipts, Social Security, unemployment).
- Fixed and variable monthly expenses (housing, utilities, transportation, medical costs).
- Assets and liabilities (bank accounts, retirement accounts, vehicles, mortgages, other loans).
- Dependents and special circumstances that affect ability to pay.
Documentation checklist (bring these when you file)
- Recent pay stubs or profit/loss statements if self-employed.
- Bank statements (last 2–3 months).
- Mortgage/rent and utility bills.
- Medical bills and payment plans.
- Statements for retirement accounts and loan balances.
- Any written offers, termination notices, or other evidence of changed circumstances.
How to fill Form 433-F effectively
- Gather documentation first — don’t estimate without support.
- Complete every line that applies; use zeros where a section doesn’t apply.
- Attach clear, labeled copies of supporting documents; include a one-page cover letter summarizing the hardship and the dates it began.
- If you’re self-employed, supply a recent profit-and-loss statement and a business bank statement.
- Sign and date the form; keep copies for your records.
Practical tips from my experience
- In my practice as a CPA and CFP®, I’ve found that a one-page narrative describing the hardship (job loss, medical emergency, drop in self-employment revenue) plus three months of bank statements accelerates review and reduces follow-up requests.
- Be conservative but honest about expenses. Inflating costs can trigger audits or denial.
- If you expect an improvement in income soon, state the timing and provide evidence (e.g., job offer letter). That helps the IRS design a temporary plan.
What happens after submission
- The IRS reviews the submission and may contact you for more documents or explanations.
- For installment agreements, the IRS will calculate a reasonable monthly payment based on allowable expenses and assets. See related guidance on setting up a payment plan: setting up an affordable installment agreement with the IRS.
- If your situation is severe, the IRS may place the account in CNC status until your financial condition improves.
Common mistakes to avoid
- Omitting bank accounts, side income, or assets.
- Using rough estimates instead of current statements.
- Failing to include required supporting documents.
- Ignoring requests from the IRS for additional information — delays may result in enforcement actions.
Timeline and response expectations
There’s no fixed processing window; typical reviews take several weeks but can be longer if the IRS requests more documentation. If you need faster relief (for example, to stop a levy), contact the IRS immediately and ask to speak with a collection representative.
When Form 433-F is not enough
The IRS sometimes requests different forms depending on the case (for example, Offer in Compromise often requires specific OIC forms). If the IRS asks for a different collection statement, complete the requested version.

When to get professional help
If your finances are complex — multiple income sources, business losses, or large asset portfolios — a tax professional or attorney can package the 433-F with supporting documents and negotiate with the IRS on your behalf. In my experience, representation reduces errors and shortens collection timelines.
