-IMFOL vs IMFOT
Within the IRS Integrated Data Retrieval System (IDRS), IMFOL (Individual Master File On-Line) command codes are used to research individual taxpayer accounts. The suffixes I and T designate two entirely different views or screens of an account's data:
1. IMFOLI (Index Screen)
- What it stands for: Individual Master File On-Line Index.
- Purpose: It acts as a table of contents or summary map for a taxpayer's account across multiple years.
- What you see: When you input a Social Security Number (SSN) with
IMFOLI, it displays a list of available tax periods (years/filing periods) and Master File Tax (MFT) codes associated with that taxpayer. It shows you at a glance which years are active on the master file and which ones have been dropped to "retention" (archive). - When to use it: You use
IMFOLIfirst when you aren't sure which specific tax years or modules exist, or if you need to find out what periods are available for research.
2. IMFOLT (Tax Module Screen)
- What it stands for: Individual Master File On-Line Tax Module.
- Purpose: It provides a detailed, line-by-line financial breakdown for a specific tax period/module.
- What you see: Once you target a specific year,
IMFOLTdisplays the posted transactions (Transaction Codes, amounts, dates), account balance, accrued interest and penalties, specific freeze codes, and credit details for that single tax year. - When to use it: You use
IMFOLTwhen you need to deep-dive into the actual financial transactions, adjustments, and history of a specific year's tax return.
Comparison Summary
| Feature | IMFOLI | IMFOLT |
|---|---|---|
| View Type | Index / Directory | Detailed Tax Module |
| Scope | Multiple years / All available modules | One specific tax period at a time |
| Primary Use | Finding which years/periods exist on the account | Examining what happened financially during a specific year |
Tip: In standard workflow, you typically check IMFOLI first to locate the correct tax period, and then pull up IMFOLT for that specific period to conduct detailed account research.
Absolutely. This page is basically explaining what an IRS employee should do when a taxpayer calls or writes about a tax adjustment and the IRS is missing some information.
The easiest way to understand it is to ignore the complicated wording and think of it as a decision tree.
1. First, understand the two terms
Tax increase
The IRS is saying:
“You owe more tax than what was originally calculated.”
For example:
- Original tax: $5,000
- IRS adjustment: +$1,000
- New tax: $6,000
So the tax increased by $1,000.
Credit increase
A credit reduces the taxpayer's tax or can produce a refund.
For example:
- Tax credit originally: $500
- Correct credit should be: $1,500
- Credit increased by $1,000
So the taxpayer may be entitled to more money/refund.
2. The first situation on the left page
The page says:
The amount of the tax increase exceeds the amount of the credit increase.
Think of it as:
Tax increase > Credit increase
Example
Suppose:
- Tax goes up $2,000
- Credit goes up $500
The tax increase is bigger.
So:
$2,000 − $500 = $1,500
The taxpayer ultimately owes $1,500 more.
What does the IRS employee do?
The table says:
- Input the adjustment.
- Contact the taxpayer to request the missing information.
- Close the case.
But there's an important note:
If the taxpayer later responds, attach the missing information to the amended return.
In simple English
IRS makes the adjustment → asks taxpayer for missing documents → closes the case.
3. The second situation is more complicated
Now the page says:
The amount of the tax increase exceeds the amount of the credit increase OR the amount of the credit exceeds the amount of the tax increase.
This section applies when the required supporting documentation is not available.
The important thing is:
The IRS doesn't have the documents it needs.
For example, the taxpayer claims a credit but hasn't provided the required proof/signatures/documentation.
The employee needs to request that information.
What does the employee do?
Step 1 — Contact the taxpayer
The employee should:
Call or write the taxpayer requesting the missing information.
In plain English:
“We need some documents/information from you before we can finish this.”
Step 2 — If writing to the taxpayer
If the IRS communicates in writing, the case is suspended for:
40 days
For an overseas taxpayer:
70 days
So remember:
🇺🇸 Regular taxpayer → 40 days 🌎 Overseas taxpayer → 70 days
Step 3 — What if the taxpayer doesn't respond?
This is very important.
If the taxpayer does not provide the missing information:
Input the tax increase only. Do not allow the credit increase.
In other words:
Tax increase = YESCredit increase = NO
Example
Suppose:
- Tax increase = $2,000
- Credit increase = $1,000
But the taxpayer doesn't provide the required documentation.
The IRS processes:
+$2,000 tax
and does not give the:
+$1,000 credit
4. What if the IRS needs to explain the difference?
The page says the IRS should correspond with the taxpayer explaining the difference in the adjustment.
Basically:
“Here is what we changed and why.”
It also mentions specific letters, such as Letter 105C or Letter 106C, depending on the situation.
You don't necessarily need to memorize all those letter numbers just to understand the main concept.
5. Now the right-hand page: the opposite situation
This is the part that can be confusing.
It says:
The amount of the credit increase exceeds the amount of the tax increase.
So:
Credit increase > Tax increase
Example
Suppose:
- Tax increase = $500
- Credit increase = $2,000
The credit is larger.
Therefore:
$2,000 − $500 = $1,500
The taxpayer may end up with a $1,500 refund.
6. But there is a problem: missing information
The taxpayer's return is missing information, such as:
- signatures
- supporting documents
- documentation needed to prove the credit
So the IRS cannot simply release the refund yet.
The procedure is:
1. Contact the taxpayer
Ask for the missing information.
2. Wait
If communicating by writing:
40 days
or:
70 days for an overseas taxpayer
3. If the taxpayer doesn't respond
The IRS inputs both the tax increase and the credit increase.
4. Freeze the overpayment
This is extremely important.
The IRS uses hold code 4 to prevent the refund from being paid immediately.
Think of it as:
🛑 “The taxpayer appears to be owed money, but don't send the refund yet.”
5. Tell the taxpayer
The IRS tells the taxpayer:
“We made the adjustment, but we're holding the refund until you provide the missing information.”
6. If the taxpayer responds
When the taxpayer finally provides the missing information:
Associate the information with the amended return → release the refund.
The whole thing in one simple picture
Think about it like this:

documents adjustmentBut there's one very important difference depending on which amount is larger.
⭐ The easiest way to memorize this
Remember these two situations:
| Situation | What happens |
|---|---|
| Tax increase > Credit increase | Tax increase is processed; credit may not be allowed if documentation is missing |
| Credit increase > Tax increase | Both are processed, but refund is held if documentation is missing |
Think of it this way:
If IRS would owe the taxpayer money → HOLD THE REFUND. 🛑
That's why the right-hand procedure says:
Use hold code 4 to freeze the overpayment.
Simple example
Let's say the taxpayer originally has:
Tax = $10,000
After adjustment:
Tax increases by $1,000
And:
Credit increases by $3,000
So:
text
Credit increase $3,000
Tax increase $1,000
-------
Net overpayment $2,000The taxpayer appears to be owed $2,000.
But the taxpayer hasn't provided the required documents.
Therefore:
IRS does NOT immediately send the $2,000.
Instead:
Hold the refund → ask for documents → taxpayer responds → verify/associate documents → release refund.
🧠 One sentence to remember the entire page
When information is missing, contact the taxpayer and give them time to respond; if the adjustment creates a refund, hold the refund until the missing information is received.
And the 40/70 rule:
40 days = regular taxpayer70 days = overseas taxpayer
If you are studying this for an IRS job/training test, I can also turn this exact page into a very simple exam-style cheat sheet with “If this happens → do this” examples and practice questions.
