The Module Story Method

When you look at a raw transaction transcript or TXMOD screen, you are not looking at disconnected numbers. You are reading a chronological timeline story.

The Realistic Module Scenario

Suppose TXMOD displays the following module for a taxpayer:

MFT:         30

TC 150       $10,000.00
TC 806        $3,000.00
TC 290        $2,000.00
TC 570             $0.00
TC 971       AC xxx
TC 846        $1,000.00

Reading the Story Step-by-Step

Step 1: TC 150 ($10,000.00)

• The Story: Original Form 1040 return posted.
• Impact: Establishes the taxpayer's initial tax liability of $10,000.00 and sets the Assessment Statute Expiration Date (ASED).

Step 2: TC 806 ($3,000.00)

• The Story: Taxpayer's employer withheld federal tax from paychecks.
• Impact: A $3,000.00 withholding credit was credited to the account.
• Subtotal at this point: Taxpayer still owes $7,000.00 ($10,000 - $3,000).

Step 3: TC 290 ($2,000.00)

• The Story: IRS processing or examination adjusted the return, assessing an additional $2,000.00.
• Impact: Total tax liability increased from $10,000 to $12,000.

Step 4: TC 570 ($0.00)

• The Story: A freeze condition was established.
• Impact: Even though the dollar amount is $0.00, this stopped system processing and prevented automated refund or credit issuance until verified.

Step 5: TC 971 AC xxx

• The Story: An action or notice was triggered.
• Impact: You investigate the Action Code (AC) to see what letter was mailed (e.g. asking for missing wage verification or identity confirmation).

Step 6: TC 846 ($1,000.00)

• The Story: Refund was issued!
• Impact: A net refund of $1,000.00 was sent to the taxpayer via check or direct deposit.
• Your Job as Support: Reconcile this refund against previous payments, credits, and adjustments so you can explain exactly how the IRS arrived at $1,000.

5-Question Module Checklist

Whenever you review a module on a live call:

1. What was the original tax assessed? (Look at TC 150)
2. What credits or payments exist? (Look at TC 806, TC 610, TC 670)
3. Were there any subsequent assessments or abatements? (Look at TC 290, TC 300, TC 301)
4. Is there an active freeze or hold? (Look at TC 570, TC 520, freeze indicators)
5. Has a refund already gone out or offset elsewhere? (Look at TC 846 or TC 826/898)
