5.2 Federal Tax Deposit (FTD) Schedules, Lookback Periods & EFTPS

Federal Tax Deposit (FTD) Schedules, Lookback Periods & EFTPS

Under federal law, employers do not hold employment taxes until quarterly or annual tax returns are filed. Instead, employers must deposit accumulated Federal Income Tax Withholding (FITW), employee FICA taxes, and employer FICA matching taxes on an ongoing, statutory schedule using the Electronic Federal Tax Payment System (EFTPS). Federal Tax Deposit (FTD) compliance is governed by Treasury Regulation § 31.6302-1 and Internal Revenue Code (IRC) § 6302.

1. The Statutory Four-Quarter Lookback Period

An employer's deposit schedule for an entire calendar year is determined before the year begins based on the employer's total employment tax liabilities reported during a specific lookback period.

+-----------------------------------------------------------------------------+

|                                                                             |
|   For Calendar Year 2026 Deposit Schedule:                                  |
|   Lookback spans July 1, 2024 through June 30, 2025 (4 Quarters)            |
|                                                                             |
|   +-------------------+-------------------+-------------------+----------+  |
|   | Q3 2024           | Q4 2024           | Q1 2025           | Q2 2025  |  |
|   | (Jul 1 - Sep 30)  | (Oct 1 - Dec 31)  | (Jan 1 - Mar 31)  | (Apr 1 - |  |
|   |                   |                   |                   |  Jun 30) |  |
|   +-------------------+-------------------+-------------------+----------+  |
|                                                                             |
|   TOTAL LOOKBACK LIABILITY = Sum of Form 941 Line 12 Across All 4 Quarters   |
+-----------------------------------------------------------------------------+

The $50,000 Classification Threshold

• Monthly Schedule Depositor: Total tax liability during the lookback period was $50,000 or less.
• Semi-Weekly Schedule Depositor: Total tax liability during the lookback period was more than $50,000.
• New Employers: An employer with no payroll history during the lookback period is treated as having a lookback liability of $0, making the new business a monthly schedule depositor for its initial calendar year (unless the $100,000 next-day rule is triggered).
• Form 944 Filers: For employers permitted to file Form 944, the lookback period is the second preceding calendar year (e.g., for calendar year 2026, the lookback is calendar year 2024).

[!IMPORTANT] Lookback Uses Reported Tax Liability, NOT Total Deposits: Lookback status is calculated strictly using the tax liability reported on Form 941 (Line 12) or Form 944, not the amounts deposited. If an employer underreported its liability or filed amended returns (Form 941-X), the corrected total tax liability governs.

2. Monthly vs. Semi-Weekly Deposit Schedules

An employer's status as a monthly or semi-weekly depositor dictates the frequency and due dates of its federal tax deposits.

+-----------------------------------------------------------------------------+
|                   MONTHLY VS. SEMI-WEEKLY DEPOSIT RULES                     |
|                                                                             |
|   MONTHLY SCHEDULE:                                                         |
|   - Taxes accumulated across any days in a calendar month                   |
|   - DUE: On or before the 15th day of the FOLLOWING month                   |
|   - (Example: All January pay dates -> Due February 15)                     |
|                                                                             |
|   SEMI-WEEKLY SCHEDULE (The Wednesday / Friday Rule):                       |
|   - Payday falls on Wednesday, Thursday, Friday  ===> Due FOLLOWING WED     |
|   - Payday falls on Saturday, Sunday, Mon, Tue   ===> Due FOLLOWING FRI     |
|                                                                             |
|   MINIMUM 3 BANKING DAYS RULE:                                              |
|   Employers always have at least 3 business banking days following the      |
|   close of the semi-weekly period to initiate and settle the deposit.       |
+-----------------------------------------------------------------------------+

Detailed Semi-Weekly Deposit Summary Table:

Semi-Weekly Periods Spanning Across Calendar Quarters

When a semi-weekly deposit period bridges two calendar quarters (e.g., Wednesday, June 30 is in Q2, and Thursday, July 1 is in Q3):

1. Both liabilities have the same deposit due date (the following Wednesday, July 7).
2. The employer must make two separate deposits via EFTPS—one designating Quarter 2 (Form 941 Q2) and one designating Quarter 3 (Form 941 Q3).
3. Combining the deposits into a single transmission causes an underpayment notice on Q2 Form 941 and an overpayment on Q3 Form 941.

3. The $100,000 Next-Day Deposit Rule

Under IRC § 6302(g), if an employer accumulates an undeposited employment tax liability of $100,000 or more on any single day during a deposit period, the accumulated taxes must be deposited by the close of the next business day.

+-----------------------------------------------------------------------------+
|                      THE $100,000 NEXT-DAY DEPOSIT RULE                     |
|                                                                             |
|   TRIGGER: Undeposited tax liability >= $100,000 on ANY day                |
|   DEADLINE: Next Business Day (EFTPS settlement)                            |
|                                                                             |
|   PERMANENT STATUS CONVERSION EFFECT:                                       |
|   If a MONTHLY depositor triggers the $100,000 rule:                        |
|   1. Must deposit the liability by the next business day.                   |
|   2. Immediately converted to a SEMI-WEEKLY depositor for:                  |
|      - The remainder of the CURRENT calendar year, AND                      |
|      - The ENTIRE SUBSEQUENT calendar year.                                 |
+-----------------------------------------------------------------------------+

Critical Nuances of the $100,000 Rule:

• Threshold Accumulation: For semi-weekly depositors, the accumulation is evaluated daily within the semi-weekly period. If an employer accumulates $60,000 on Wednesday and $45,000 on Thursday, the $100,000 rule is triggered on Thursday (ext{Total} = $105,000), and the entire $105,000 must be deposited on Friday (the next business day).
• Quarter-End Application: The $100,000 threshold does not carry over across quarter boundaries. Accumulation resets at the start of each new quarter.

4. Deposit Safe Harbor / Shortfall Rules

To prevent harsh penalties for minor mathematical errors or unexpected payroll adjustments, Treasury Regulation § 31.6302-1(e) provides a Safe Harbor Shortfall Rule.

+-----------------------------------------------------------------------------+
|                       SAFE HARBOR SHORTFALL MECHANICS                       |
|                                                                             |
|   SAFE HARBOR CRITERIA:                                                     |
|   The deposit shortfall does not exceed the GREATER of:                     |
|   - $100, OR                                                                |
|   - 2% (0.02) of the total required tax liability for the deposit period.   |
|   (In other words, at least 98% of the required liability was deposited)    |
|                                                                             |
|   REQUIRED MAKE-UP DEPOSIT DUE DATES:                                       |
|   - MONTHLY Depositors:                                                     |
|     Due on or before the Form 941 quarterly return due date (e.g., Apr 30)  |
|                                                                             |
|   - SEMI-WEEKLY Depositors:                                                 |
|     Due on or before the FIRST Wednesday or Friday falling ON or AFTER     |
|     the 15th of the month following the month the deposit was due,          |
|     or by the Form 941 return due date, whichever is EARLIER.               |
+-----------------------------------------------------------------------------+

5. Electronic Federal Tax Payment System (EFTPS) & Penalties

Under Treasury Regulation § 31.6302-1(h), all federal tax deposits must be made electronically through EFTPS.

+-----------------------------------------------------------------------------+
|                        EFTPS TRANSMISSION PROTOCOLS                         |
|                                                                             |
|   [ACH DEBIT (EFTPS Direct)]                                                |
|   - Employer instructs EFTPS to pull funds from company bank account.       |
|   - HARD CUTOFF: Must be submitted by 8:00 PM Eastern Time at least         |
|     ONE CALENDAR DAY prior to the statutory deposit due date.               |
|                                                                             |
|   [ACH CREDIT (Financial Institution Push)]                                 |
|   - Employer instructs commercial bank to originate NACHA ACH credit.       |
|   - Bank must transmit early enough to settle on the due date.              |
|                                                                             |
|   [SAME-DAY WIRE (Fedwire / ETA Backup)]                                    |
|   - Emergency mechanism if 8:00 PM ET deadline missed on due date.          |
|   - Requires specific Electronic Tax Application (ETA) Fedwire format.      |
+-----------------------------------------------------------------------------+

Failure-to-Deposit Penalty Structure (IRC § 6656)

The IRS assesses tiered civil penalties under IRC § 6656 based on the degree of delinquency:

+-----------------------------------------------------------------------------+
|                    IRC § 6656 FAILURE-TO-DEPOSIT PENALTIES                  |
|                                                                             |
|   Delinquency Period                               Penalty Rate             |
|   -----------------------------------------------  ------------------------ |
|   1 to 5 calendar days late                        2% of unpaid amount      |
|   6 to 15 calendar days late                       5% of unpaid amount      |
|   More than 15 calendar days late                  10% of unpaid amount     |
|   Paid directly to IRS or not via EFTPS            10% of unpaid amount     |
|   More than 10 days after 1st IRS Notice (Demand)  15% of unpaid amount     |
+-----------------------------------------------------------------------------+

[!CAUTION] Direct Payment to IRS Triggers 10% Penalty: If an employer required to use EFTPS sends a paper check directly to the IRS with Form 941 (when liability exceeds the $2,500 quarterly return threshold), the IRS imposes a mandatory 10% failure-to-deposit penalty, even if the check was received by the IRS on or before the deposit due date.

6. Comprehensive Computational Examples

Example 1: Lookback Determination & Deposit Schedule Assignment

Scenario: A company reported the following tax liabilities on Line 12 of its Forms 941 during the lookback period for calendar year 2026:

• Q3 2024: $12,400.00
• Q4 2024: $14,200.00
• Q1 2025: $11,800.00
• Q2 2025: $13,100.00

$\text{Total Lookback Liability} = \$12,400 + \$14,200 + \$11,800 + \$13,100 = \$51,500.00$

Determination: Because the total lookback liability of $51,500.00 exceeds $50,000.00, the company is classified as a Semi-Weekly Schedule Depositor for the entirety of calendar year 2026.

Example 2: Semi-Weekly Deposit Due Date and $100,000 Rule

Scenario: In 2026, the employer pays wages on the following schedule:

• Friday, October 9, 2026: Payroll liability incurred = $42,000.00
• Tuesday, October 13, 2026: Executive bonus liability incurred = $65,000.00

Analysis:

1. Friday, Oct 9 falls in the Wednesday-Friday semi-weekly period (due Wednesday, Oct 14).
2. Tuesday, Oct 13 falls in the Saturday-Tuesday semi-weekly period (due Friday, Oct 16).
3. On Tuesday, Oct 13, undeposited taxes for that specific semi-weekly period are $65,000 (under $100,000).
4. Therefore:
   • The $42,000 liability must be deposited by Wednesday, October 14, 2026 (ACH Debit initiated by 8:00 PM ET on Tuesday, Oct 13).
   • The $65,000 liability must be deposited by Friday, October 16, 2026 (ACH Debit initiated by 8:00 PM ET on Thursday, Oct 15).

Example 3: Safe Harbor Shortfall Calculation and Make-Up Due Date

Scenario: A semi-weekly depositor has a total tax liability of $80,000.00 on Friday, March 6, 2026. On Wednesday, March 11, 2026, the company deposits $78,500.00.

1. Shortfall Determination: $\text{Shortfall} = \$80,000.00 - \$78,500.00 = \$1,500.00$ $\text{Allowable Safe Harbor (2\%)} = \$80,000.00 \times 0.02 = \$1,600.00$ Because the actual shortfall of $1,500.00 is less than $1,600.00 (and greater than $100), the safe harbor is satisfied and no late penalty applies immediately.

2. Make-Up Due Date Determination:

   • The deposit was due in March.
   • The 15th day of the month following March is April 15.
   • The first Wednesday or Friday falling on or after April 15, 2026 is Wednesday, April 15, 2026 (or Friday, April 17).
   • Form 941 due date for Q1 is April 30, 2026.
   • The earlier date is April 15/17, so the employer must deposit the $1,500.00 shortfall on or before that date.
