What Schedule B (Form 941) Is For
Schedule B (Form 941) (2018) is designed for semiweekly schedule depositors to report their daily employment tax liabilities to the IRS. This form tracks when a tax liability occurred for federal income tax, Social Security, and Medicare taxes, ensuring that each deposit aligns with the correct payroll date. It provides the IRS with a clear record that employers have made timely deposits for employment taxes and followed the proper deposit schedule required under the Federal Unemployment Tax Act (FUTA). This process helps prevent deposit penalties, reconciles reported wages, and confirms compliance with federal deposit rules for both the employer and employee portions of FICA taxes.

When You’d Use Schedule B (Form 941)
Employers file Schedule B (Form 941) (2018) when their employment tax liability or deposit schedule requires detailed tracking throughout the quarter.
- Semiweekly Schedule Depositor: You must file this form if your lookback period indicates that you reported more than $50,000 in federal employment taxes, which classifies you as a semiweekly depositor for the current calendar year.
- $100,000 Next-Day Rule: You are required to file Schedule B if your employment tax liability reaches $100,000 or more on a single business day, which triggers the next-day deposit requirement and semiweekly depositor status for the remainder of the year.
- Late or Amended Returns: You must include Schedule B when filing a late Form 941 or when submitting an amended tax return that corrects prior reporting without altering the original daily liabilities.
- Quarterly Filing Obligation: You are required to attach Schedule B to each quarterly Form 941 by its due date to confirm accurate reporting and avoid potential failure-to-deposit penalties.
If late payroll tax deposits have led to IRS fines, our penalty abatement resources for employment taxes can help you reduce or eliminate those penalties.
Key Rules or Details for 2018
Several vital rules defined how employers were required to file Schedule B (Form 941) (2018) and deposit their employment taxes throughout the year.
- Tax Rates: The Social Security and Medicare tax rates for 2018 remained unchanged from the previous year, with a combined rate of 12.4% for Social Security and 2.9% for Medicare. Additionally, the Additional Medicare Tax of 0.9% applies to employees earning above $200,000.
- Deposit Timing: Semiweekly depositors were required to deposit taxes within three banking days after their wages were paid. Any delay in depositing taxes could result in a deposit penalty based on the number of days late.
- Next-Day Deposit Rule: Employers who reached a tax liability of $100,000 or more on any single day were required to make a next-day deposit and automatically became semiweekly depositors for the remainder of the calendar year.
- Payroll Tax Credits: Employers who claimed the qualified small business payroll tax credit using Form 8974 were allowed to reduce only the employer’s portion of Social Security tax, ensuring that daily liabilities were not reduced below zero.
- Deposit Periods and Legal Holidays: Deposit deadlines exclude Saturdays, Sundays, and legal holidays in the District of Columbia, meaning any due date falling on such days is shifted to the next business day.

Step-by-Step (High Level)
Completing Schedule B (Form 941) (2018) requires accuracy and attention to the timing of your employment tax liabilities throughout each quarter.
- Collect Payroll Records: Gather all payroll data for the quarter, including wages paid and withholdings for federal income tax, Social Security, and Medicare taxes for each payday.
- Calculate Liabilities: Add together the total federal income tax withheld, the employer and employee shares of Social Security and Medicare taxes, and any Additional Medicare Tax withheld to determine your daily employment tax liability.
- Record Daily Amounts: Enter the exact employment tax liability on the line corresponding to the date wages were paid in each month’s section of Schedule B to ensure that every payday is reported individually.
- Reconcile Totals: Add all the daily liabilities for the quarter and verify that the total matches the amount reported on line 12 of Form 941 to prevent discrepancies or processing delays.
- Attach and File Properly: Check the appropriate quarter box at the top of the form, attach Schedule B to Form 941, and file electronically or by mail by the due date to maintain compliance with IRS filing requirements.

Common Mistakes and How to Avoid Them
Avoiding errors when completing Schedule B (Form 941) (2018) is essential to prevent unnecessary IRS notices and deposit penalties.
- Reporting Deposits Instead of Liabilities: Many employers mistakenly list deposit dates and amounts instead of the dates wages were paid, so you should always enter your tax liability on the exact payday to reflect when it was incurred.
- Combining Multiple Paydays: Some filers combine several paydays into one entry to save time, but you must report each payday separately to ensure the IRS can verify your deposit schedule accurately.
- Math Errors in Calculations: Errors in totaling federal income tax, Social Security, and Medicare taxes are ordinary, so always double-check calculations for each payday to ensure your daily tax liabilities are correct.
- Incorrect 941-X Adjustments: Some employers adjust their Schedule B when filing Form 941-X, but you should never modify the original Schedule B liabilities since corrections must be reported solely on the amended return.
- Ignoring Credits or Carrying Back Amounts: If you claim payroll tax credits, you must apply them only to the employer’s share of Social Security tax for current liabilities and never reduce prior or unrelated paydays.

What Happens After You File
Once you file Form 941 with Schedule B (Form 941) (2018), the IRS compares your reported employment tax liabilities against your actual deposit records from the Electronic Federal Tax Payment System (EFTPS). Suppose the deposits do not align with your daily liabilities or are submitted late. In that case, the IRS may assess tiered failure-to-deposit penalties ranging from 2% to 15% based on the length of the payment's overdue period. Properly completed forms help prevent averaged penalty calculations and confirm that all payroll tax deposits were made according to the semiweekly deposit schedule.
