The AI checks your answers before you download

13 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

SSN/ITIN Format and Presence

Validates that the Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) in Section 1 is entered in a valid 9-digit format (e.g., XXX-XX-XXXX or XXXXXXXXX). This is a critical identifier for the IRS to correctly associate the form with the taxpayer's account. Failure to provide a valid number will prevent form processing and require resubmission.

Conditional Spouse Information Requirement

Checks if the 'Married' status is selected in Section 1. If it is, this validation ensures that the spouse's first name, last name, date of birth, and Social Security Number are all provided. This information is essential for the IRS to have a complete financial picture of the household. If these fields are left blank while 'Married' is checked, the form will be considered incomplete.

Date of Birth and Marriage Date Validity

Ensures all date fields, such as 'Date of birth' and 'Date of marriage', are in a valid mm/dd/yyyy format and represent a logical date in the past. For example, the date of birth cannot be a future date, and the date of marriage cannot be before the taxpayer's date of birth. This prevents data entry errors that would create an invalid record and cause processing delays.

Non-Negative Financial Value Enforcement

Ensures that all monetary fields throughout the form, including asset values, income, and expenses, contain only zero or positive numbers, as explicitly stated in the instructions. The form states that negative numbers should be entered as '0'. This rule prevents calculation errors and ensures that financial deficits in one area do not improperly reduce the overall net worth calculation.

Asset Value Calculation Accuracy (Section 3)

Verifies that the calculations for asset values in Section 3 are performed correctly according to the form's instructions (e.g., Current Market Value x 0.8 - Loan Balance). These calculations are fundamental to determining the taxpayer's 'Available Individual Equity in Assets' (Box A). An incorrect calculation will lead to an inaccurate minimum offer amount and will likely cause the offer to be rejected.

Vehicle Value Logic for Leased vs. Owned

Verifies the logic for vehicles in Section 3. If the 'Lease' checkbox is selected for a vehicle, this validation ensures that the 'Total value of vehicle' (line 6a or 6c) is entered as '0', as instructed. This is important to prevent the value of a non-owned, leased asset from being incorrectly included in the taxpayer's total equity, which would wrongly inflate the minimum offer amount.

Common Mistakes in Completing Form 433-A (OIC)

The ones the AI is built to catch.

Reporting Net Income Instead of Gross Income

Section 7 asks for gross monthly income before any taxes or deductions are taken out. A frequent mistake is entering take-home (net) pay, which significantly understates the household's actual income and ability to pay. This misrepresentation can cause the IRS to reject the offer. To avoid this, always use the pre-tax amount shown on your pay stubs and earnings statements.

Miscalculating Asset Equity Using IRS Formulas

The form requires specific calculations, such as multiplying the market value of real estate and vehicles by 80% (0.8) before subtracting loans. People often use the full market value or make simple arithmetic errors, leading to an inaccurate 'Available Equity' figure. This can cause the IRS to reject the offer for being too low. To prevent this, use a calculator for each step and double-check your math, or use a tool that automates these calculations.

Failing to Add Back Non-Cash Business Expenses

For self-employed filers, Section 7 (Line 36) requires that non-cash expenses like depreciation must be added back to the net business income from Box C. Many people forget this step, as depreciation is a normal deduction on a tax return. This error artificially lowers your reported monthly income, resulting in an understated and incorrect minimum offer amount that the IRS will flag for correction.

Using Actual Expenses Instead of Allowable IRS Standards

A note in Section 7 specifies that for expenses like 'Food, clothing, and miscellaneous' (Line 39), you should enter the full allowable IRS standard amount, even if your actual spending is less. Many people enter their lower, actual costs, which works against them by making their disposable income appear higher. This results in a higher calculated minimum offer, so you should always look up and use the correct national or local standard.

Omitting Digital Assets and Other Financial Accounts

The form requires disclosing all assets, including cryptocurrency, NFTs, online payment accounts (e.g., PayPal), and old retirement plans. People often forget small accounts or are unsure how to value and report digital assets, leading to omissions. Failing to disclose all assets is a serious error that can lead to immediate rejection of the offer and potential penalties for providing false information.

Failing to Include All Required Documentation

Section 10 lists numerous required attachments, such as three months of bank statements, recent pay stubs, and loan statements. Submitting the form without all necessary supporting documents is a primary reason for an offer to be returned as unprocessable. This causes significant delays and requires a complete resubmission. To avoid this, create a checklist from Section 10 and gather all documents before sending.

Misapplying Vehicle and Bank Account Exemptions

The form allows specific deductions, such as subtracting $1,000 from cash/bank accounts (Line 1) and $3,450 from a vehicle's value (Line 6b). Filers often miss these deductions entirely or make mathematical errors when applying them. This leads to an overstatement of available assets and a higher calculated minimum offer. AI-powered form-filling tools like Instafill.ai can help prevent these errors by automatically applying these calculations correctly.

Not Disclosing All Household Income Contributions

The IRS evaluates the entire household's financial situation, not just the taxpayer's. A common mistake is omitting income contributions from other household members like an adult child, a partner, or a roommate, as required in Sections 1 and 7. This under-reports the total household income available to pay expenses and can be seen as a misrepresentation of the ability to pay.

Using the Incorrect Multiplier in the Final Offer Calculation

In Section 8, the 'Remaining Monthly Income' (Box F) is multiplied by either 12 or 24, depending on the proposed payment timeframe. Using the wrong multiplier will result in a completely incorrect 'Minimum Offer Amount.' This fundamental error invalidates the final calculation and will require a full correction. Carefully read the instructions for Box G and Box H to select the multiplier that matches your payment plan.

Submitting an Incomplete or Illegible Form

This is a long and complex form, and it is often available only as a non-fillable PDF, leading to handwritten submissions. Common mistakes include leaving required fields blank, providing illegible handwriting, or making calculation errors that are hard to trace. This can cause processing delays or an outright rejection. Using a service like Instafill.ai can convert the flat PDF into an interactive, fillable form, ensuring all data is legible, validated, and correctly calculated.
