What is Form 433-A?
Quick Facts: Form 433-A is the IRS Collection Information Statement used for wage earners and self-employed individuals seeking IRS payment agreements above certain thresholds, or OIC (Offer in Compromise). It details assets, liabilities, income, expenses, and household information for the IRS to assess collection potential.
If a client owes a large IRS balance (typically above $50,000 or is self-employed or dealing with a Revenue Officer), the IRS will require Form 433-A to evaluate any request for a payment plan or an OIC. More info: About Form 433-A – IRS.gov
Who Must File Form 433-A?
Taxpayers who are individuals (wage earners or self-employed), including sole proprietors, must file Form 433-A upon request when:
- Requesting an installment agreement above $50,000
- Applying for an Offer in Compromise
- Revenue Officer investigations
Business entities should use Form 433-B. For simple individual collection issues below $50,000, Form 433-F is typically used.

Frequently Asked Questions
How long does IRS Form 433-A processing take?
30-60 days is typical for Revenue Officer review; ACS (phone-based cases) may take longer. Missing info causes delays.
Can I claim expenses above IRS standards?
Only with documentation and strong rationale (e.g. documented high medical expenses). Must be truly necessary, not discretionary.
What if assets/income are understated?
The IRS may deny an agreement and can refer the case for fraud investigation if it appears intentional. Provide full, accurate, and honest information.
What if my financial situation changes?
Notify the IRS and submit an updated form if major changes affect your ability to pay. This may lower or increase payments.
Do I include retirement balances?
Yes, all retirement balances are disclosed, but the IRS may exempt these from levy. Still, balances affect Offers in Compromise calculation.
How far back do bank statements need to go?
The last 3 months for each account is standard; use the most recent available.
Should I hire a tax professional?
For complex debts or if self-employed, a professional ensures correct completion. See Uncle Kam’s tax resolution services.
