IRS Form 433-A vs Form 433-F
Both forms tell the IRS what you earn, what you own, and what you can afford to pay. Which one you file dictates whether you get a streamlined installment agreement, an Offer in Compromise, or a request for more information that restarts the clock on collection.

How This Affects Fresh Start Eligibility
The IRS Fresh Start Initiative expanded streamlined installment agreements to individual taxpayers who owe $50,000 or less and can pay the balance within 72 months. At that threshold, the ACS unit will accept Form 433-F — often with no supporting documents. Cross the $50,000 line, or ask for a non-streamlined agreement, and the IRS demands Form 433-A plus bank statements, pay stubs, and expense documentation. For an Offer in Compromise under Fresh Start's relaxed RCP formula, only Form 433-A (OIC) will do.
- You owe $50,000 or less
- Your income is W-2
- You want a streamlined 72-month plan
- ACS (not a Revenue Officer) is calling
- You owe more than $50,000
- You're self-employed with business assets
- A Revenue Officer is assigned
- You're pursuing an Offer in Compromise
Common Mistakes That Cost Taxpayers Money
Submitting Form 433-F to a Revenue Officer — the officer sends it back and issues a Form 9297 deadline, restarting collection pressure.
Filing Form 433-A (OIC) without the RCP worksheets — the IRS returns the offer as processable-but-unsubstantiated and keeps your $205 user fee.
Understating monthly expenses because you didn't reference the IRS Collection Financial Standards — the IRS caps housing, transportation, and food expenses; filing without the standards inflates your ability-to-pay number.
Overstating dissipated assets — the IRS adds back retirement or real-estate proceeds spent in the last 3 years, blowing up the RCP calculation.
Signing before verifying the bank routing number on any attached Form 433-D — a single wrong digit triggers a CP523 default.

A senior tax attorney can tell you within minutes which form the IRS will accept in your case — and, more importantly, what numbers to put on it so you don't hand the IRS a bigger monthly payment or a rejected Offer in Compromise.
