Form 940 — Employer's Annual Federal Unemployment (FUTA) Tax Return
Form 940 reports and remits the employer-only Federal Unemployment Tax Act (FUTA) tax. Unlike Social Security and Medicare taxes, FUTA is paid exclusively by employers — employees do not contribute. This tax funds state workforce agencies and the federal share of unemployment compensation programs.
Who Must File Form 940
Under IRC §3306(a), you must file Form 940 if you meet either of these tests in the current or preceding calendar year:
Exempt wages: Certain payments are exempt from FUTA under IRC §3306(b), including payments to a spouse, a child under 21 employed by a parent, certain statutory non-employees (direct sellers, qualified real estate agents under IRC §3508), payments under a cafeteria plan (IRC §125), employer contributions to qualified retirement plans, and group-term life insurance (IRC §7702).
State-specific exclusions: Some states exclude officers of certain corporations, members of LLCs, or partners from SUTA coverage. However, the FUTA filing requirement is determined under federal rules, not state rules. You may owe FUTA even if a state exempts an individual from SUTA.
When to File & Deposit
Form 940 is an annual return, but FUTA tax is deposited on a quarterly basis when the accumulated liability exceeds $500.
| Action | Deadline | Notes |
|---|---|---|
| File Form 940 | January 31 of the following year | Extended to February 10 if all FUTA tax was deposited on time throughout the year |
| Q1 Deposit (Jan–Mar) | April 30 | Required only if cumulative FUTA liability exceeds $500 |
| Q2 Deposit (Apr–Jun) | July 31 | Required only if cumulative FUTA liability exceeds $500 |
| Q3 Deposit (Jul–Sep) | October 31 | Required only if cumulative FUTA liability exceeds $500 |
| Q4 Deposit (Oct–Dec) | January 31 (with return) | Or pay with Form 940 if total annual tax is $500 or less |
If you paid wages in a state that has an outstanding federal unemployment loan (a "credit reduction state"), your FUTA credit is reduced, increasing your effective FUTA rate above the standard 0.6%. The Department of Labor publishes the list of credit reduction states annually, typically in November. For 2026, check IRS.gov/form940 for the current list. Each credit reduction state adds 0.3% (or more) per year the loan remains outstanding. You must complete Schedule A (Form 940) if you paid wages in any credit reduction state.

Part 4 — Determine Your FUTA Tax and Balance Due or Overpayment
Part 5 — Report Your FUTA Tax Liability by Quarter
For employers with full-time salaried staff, most or all employees will hit the $7,000 FUTA wage base during Q1. This means the vast majority of your annual FUTA liability accrues by March 31 and must be deposited by April 30. Failing to make the Q1 deposit is the single most common FUTA deposit violation. Set a calendar reminder for mid-April.
Schedule A (Form 940) — Multi-State Employer and Credit Reduction
Schedule A is required if you paid wages in more than one state or in any credit reduction state. The schedule lists all states and U.S. territories, and you enter the FUTA taxable wages paid in each jurisdiction.
Form 944 (Employer's Annual Federal Tax Return) is obsolete beginning with the 2026 tax year. Employers who previously filed Form 944 must now file Form 941 on a quarterly basis. If you have clients who were Form 944 filers, ensure they are transitioned to quarterly Form 941 filing and are aware of the new deposit schedule requirements. The FUTA obligation on Form 940 is unaffected by this change.
Common Mistakes & How to Avoid Them
| Mistake | Impact | How to Avoid |
|---|---|---|
| Failing to deposit Q1 FUTA on time | Failure-to-deposit penalty (2%–15%) | Calendar the April 30 deposit deadline; most FUTA liability accrues in Q1 for full-time staff |
| Not computing Line 5 correctly | Overpayment or underpayment of FUTA | Run a per-employee wage cap report. Each employee maxes at $7,000. Verify mid-year hires and terminated employees carefully. |
| Missing credit reduction states | Underpayment and IRS assessment of additional tax plus penalties | Check the DOL credit reduction list each November. File Schedule A if you had wages in any affected state. |
| Paying state unemployment tax late | Loss of the entire 5.4% credit for that state's wages, increasing FUTA rate from 0.6% to 6.0% | Pay SUTA by the Form 940 due date (or apply for the Line 11 exception). Automate SUTA payments. |
| Including exempt wages in Line 3 | Overstating FUTA taxable base | Ensure exempt payments (Line 4) are properly categorized and deducted |
| Failing to reconcile with quarterly returns | IRS cross-reference mismatch (CP notices) | Total wages on Form 940 should reconcile with aggregate Forms 941/943 wages, adjusted for payments not subject to FUTA |

Practitioner Pro Tips
Under IRC §3302, the 5.4% FUTA credit is available only if state unemployment taxes are paid by the due date of the Form 940 (January 31, or February 10 if the extended date applies). If your client pays SUTA late — even by a single day — the credit for those wages is lost. This turns a $42 per-employee tax (0.6% × $7,000) into a $420 per-employee tax (6.0% × $7,000). For a 500-employee company, that is a $189,000 penalty. Automate SUTA payments and verify they post before year-end.
Before filing Form 940, reconcile total wages across all four quarterly Form 941 filings (or Form 943 for agricultural employers) against Form 940 Line 3. Discrepancies are a top IRS audit trigger. Common causes of mismatches: amended quarterly returns not reflected, W-2c corrections, successor employer situations, and mid-year payroll provider changes. Use a four-column reconciliation worksheet (Q1 through Q4) mapped to W-3 totals.
If you acquire another business during the year, IRC §3306(b)(1) allows you to count wages the predecessor paid toward the $7,000 FUTA wage base — but only if specific successor employer criteria are met (IRC §3306(b)(1) and Rev. Rul. 62-60). Failing to apply the successor rule means over-counting FUTA wages. Applying it incorrectly means under-counting. Document the acquisition date, predecessor's EIN, and each transferred employee's year-to-date wages.
When configuring FUTA tax in MasterTax™, ensure that each state jurisdiction's SUTA wage base and rate table is updated before Q1 processing. The system's auto-credit calculation depends on accurate state wage base mapping. Verify the credit reduction state settings annually after the DOL publishes the final list (typically mid-November).
Form 941 — Employer's Quarterly Federal Tax Return
Form 941 is the cornerstone of federal employment tax compliance. Filed quarterly, it reports income taxes withheld from employee wages plus both the employer and employee shares of Social Security and Medicare taxes (FICA). This is the most frequently filed employment tax return and is subject to the most intensive IRS compliance programs.
Who Must File Form 941
Under IRC §6011 and Treas. Reg. §31.6011(a)-1, every employer who pays wages subject to federal income tax withholding or Social Security and Medicare taxes must file Form 941 quarterly, unless they are:
Beginning with the 2026 tax year, Form 944 (Employer's Annual Federal Tax Return) is obsolete. Previously, the IRS allowed certain small employers with annual employment tax liability of $1,000 or less to file annually on Form 944 instead of quarterly on Form 941. This option no longer exists. All former Form 944 filers must now transition to quarterly Form 941 filing. Ensure these employers are set up with proper deposit schedules and quarterly filing reminders.
When to File & Deposit
| Quarter | Quarter Dates | Form 941 Due Date |
|---|---|---|
| Q1 | January 1 – March 31 | April 30 |
| Q2 | April 1 – June 30 | July 31 |
| Q3 | July 1 – September 30 | October 31 |
| Q4 | October 1 – December 31 | January 31 |
If the due date falls on a Saturday, Sunday, or legal holiday, the return is due the next business day (IRC §7503). Deposit due dates follow the same rule, but note that EFTPS (Electronic Federal Tax Payment System) considers the settlement date, not the submission date. Initiate deposits at least one business day before the due date to ensure timely settlement.
Deposit Schedules Explained
The IRS assigns your deposit schedule based on your lookback period liability (the four quarters ending June 30 of the prior year). Under Treas. Reg. §31.6302-1, there are two deposit schedules:
Many employers are unaware that triggering the $100,000 threshold even once reclassifies them as semiweekly depositors for the rest of the current year AND the next calendar year. A single large bonus payroll in December can change your deposit schedule for all of the following year. Plan large payrolls with your deposit obligations in mind.

Schedule B (Form 941) — Report of Tax Liability for Semiweekly Schedule Depositors
Semiweekly depositors must complete Schedule B showing their daily tax liability for each day of the quarter. This is not a record of deposits made — it is a record of when tax liability was incurred (the date wages were paid or tips were reported).
Schedule B reports the date the liability arose (payroll date), not the date the deposit was made. This is the #1 error on Schedule B. When the IRS applies the semiweekly deposit rules, they compare your liability dates (from Schedule B) to your deposit dates (from EFTPS records). If your Schedule B shows liability on the wrong date, the IRS may assess penalties even though your deposits were timely. For example, if you pay employees on Friday but your Schedule B shows the liability on the following Monday, your "on-time" Friday deposit now appears 3 days early relative to the Monday liability — and the IRS may think a separate Monday liability was deposited late.
Common Mistakes & How to Avoid Them
| Mistake | Impact | How to Avoid |
|---|---|---|
| Schedule B shows deposit dates instead of liability dates | Erroneous FTD penalty assessment (often $10,000+) | Use payroll date (check date), not the date you initiated the EFTPS deposit |
| Not tracking Social Security wage base mid-quarter | Over-withholding or under-withholding FICA | Flag employees approaching $176,100 in YTD wages; stop SS withholding at the cap. Medicare has no cap. |
| Missing the Additional Medicare Tax threshold | Under-withholding, employee owes on personal return, employer may face penalties | Begin withholding 0.9% on wages exceeding $200,000 per employee per calendar year — use cumulative YTD tracking |
| Line 2 vs. Line 5a mismatch | IRS inquiry letter (CP2100) | Understand that Line 2 (income tax wages) and Line 5a (SS wages) differ due to pre-tax deductions (401k, cafeteria plans) that reduce income tax wages but not FICA wages (for most plans) |
| Forgetting to report third-party sick pay | Under-reporting FICA liability | Coordinate with insurance carrier — obtain Form 8922 and adjust Lines 5a/5c for sick pay they reported on your behalf |
| Filing a zero return late | Failure-to-file penalty (even on $0 returns) | File Form 941 every quarter even if you had no employees or wages. Use Line 18 to indicate seasonal or final return status. |
| Wrong deposit schedule selection on Line 16 | Automatic FTD penalty assessment | Confirm your lookback period liability each January. Use IRS Publication 15 (Circular E), Section 11, to determine your schedule. |

Practitioner Pro Tips
Every January, before filing Q4 Form 941, run a four-quarter reconciliation. Sum all four quarterly returns (Lines 2, 3, 5a, 5c, 5d) and compare against projected W-2/W-3 totals. Discrepancies must be resolved before filing Q4 — correcting them later via Form 941-X is time-consuming and may trigger examination. Common causes of drift: mid-quarter hires/terms with partial-period wages, memo adjustments in the payroll system that do not flow to tax reporting, and reclassified workers (1099 to W-2 conversions).
Section 401(k) deferrals reduce federal income tax wages (Line 2) but do not reduce FICA wages (Lines 5a, 5c). Section 125 cafeteria plan deductions reduce both income tax and FICA wages. Section 132(f) qualified transportation fringe benefits reduce income tax wages but not FICA wages (up to the exclusion limit). Group-term life insurance over $50,000 (IRC §79) is exempt from income tax withholding but subject to FICA. These distinctions cause the perennial Line 2 vs. Line 5a mismatch that confuses preparers and triggers IRS notices. Document the reconciling items clearly.
When running quarterly reconciliation in MasterTax™, leverage the system's tax-type summary reports to compare gross wages by tax code (FIT, SS EE, SS ER, MED EE, MED ER, Add'l Med) against Form 941 line items. Discrepancies between the payroll platform's gross-to-net calculation and the quarterly return almost always stem from manual adjustments, voided checks, or retroactive pay rate changes that were not properly reflected in the tax accumulation. Run the MasterTax™ reconciliation report before filing each quarter.
Always use EFTPS for deposits (required for most employers under Treas. Reg. §31.6302-1(h)). Key practices: (1) Initiate deposits at least one business day before the due date to ensure timely settlement. (2) Retain the EFT acknowledgment number for each deposit — this is your proof of deposit in case of an IRS dispute. (3) Set up a secondary authorized signer in EFTPS in case the primary contact is unavailable. (4) If your EFTPS payment fails or is rejected, contact EFTPS customer service immediately and make the deposit via same-day wire (Form 8109 is no longer available). (5) Reconcile EFTPS deposit history to your quarterly returns before filing.
Paid Family and Medical Leave (PFML) is a major tax code with its own dedicated state reporting form. PFML contributions are reported to the state, not on Form 941. However, PFML does interact with Form 941 in subtle ways: PFML wage bases may differ from the Social Security wage base, and PFML-exempt employees must still be tracked for federal FICA purposes. In states like Hawaii and New York where PFML premiums are paid to a private insurance carrier rather than a government agency, ensure your payroll system correctly distinguishes between state insurance premiums and federal employment taxes. Do not co-mingle PFML amounts with Form 941 liabilities.
Form 943 — Employer's Annual Federal Tax Return for Agricultural Employees
Form 943 is the agricultural employer's equivalent of Form 941 — but filed annually instead of quarterly. It reports federal income tax withheld from farmworkers' wages plus the employer and employee shares of Social Security and Medicare taxes. Agricultural employers have unique coverage thresholds, deposit rules, and worker classification considerations that differ significantly from non-agricultural employment.
Who Must File Form 943
You must file Form 943 if you paid wages to one or more farmworkers that were subject to Social Security, Medicare, or federal income tax withholding. The key determination is whether the work qualifies as "agricultural labor" under IRC §3121(g).
If you employ both agricultural and non-agricultural workers, you must file both Form 943 (for farmworkers) and Form 941 (for non-farm employees). You must also file Form 940 (FUTA) if you meet the FUTA filing thresholds for either category. The worker classification determines which return applies — not the nature of the overall business. A farm that also operates a retail store must file Form 943 for field hands and Form 941 for store clerks.
Agricultural Worker Coverage Rules
Agricultural employment has unique coverage thresholds under IRC §3121(a)(8) that differ from standard employment. A farmworker's wages are subject to FICA only if one of two tests is met:
Both the $150 test and the $2,500 test are retroactive. If a farmworker is paid $100 in March and $60 in October ($160 total), the entire $160 is subject to FICA — including the $100 paid in March, before the threshold was reached. This means you may need to make retroactive FICA deposits. Similarly, if your annual farm labor expenditures do not reach $2,500 until November, all wages paid from January forward become subject to FICA. Track cumulative wages carefully throughout the year.
When to File & Deposit
| Action | Deadline | Notes |
|---|---|---|
| File Form 943 | January 31 of the following year | Extended to February 10 if all taxes were deposited in full and on time during the year |
| Monthly deposits | 15th of the following month | If lookback period liability is $50,000 or less |
| Semiweekly deposits | Wed/Fri rule (same as Form 941) | If lookback period liability exceeds $50,000 |
| Annual deposit | With return (January 31) | If total annual tax is less than $2,500 and no $100,000 next-day obligation was triggered |
The lookback period for Form 943 filers is the second preceding calendar year (not the four-quarter lookback used for Form 941). For 2026, the lookback period is calendar year 2024. If your total Form 943 tax liability for 2024 was $50,000 or less, you are a monthly depositor for 2026. If it exceeded $50,000, you are a semiweekly depositor. The $100,000 next-day deposit rule applies to agricultural employers the same way it applies to Form 941 filers.

H-2A Visa Worker Special Rules
H-2A temporary agricultural workers have unique tax treatment that agricultural employers must carefully navigate:
Many agricultural operations employ a mix of H-2A visa holders, domestic seasonal workers, and year-round farm employees. Each category has different tax treatment. H-2A workers: no FICA, no FITW, no FUTA. Domestic farmworkers subject to the $150/$2,500 thresholds: FICA and FITW apply once thresholds are met. Year-round farm managers exceeding thresholds from day one: full FICA, FITW, and FUTA coverage. Miscategorizing workers across these groups is one of the most expensive agricultural payroll errors. Maintain separate payroll codes for each worker category.
Common Mistakes & How to Avoid Them
| Mistake | Impact | How to Avoid |
|---|---|---|
| Withholding FICA from H-2A workers | Over-withholding, refund claims, worker complaints | Set up a dedicated H-2A payroll code with FICA and FITW exempt flags |
| Not monitoring the $150/$2,500 thresholds | Failure to withhold/deposit FICA retroactively | Track cumulative cash wages per worker and total farm labor expense weekly during peak season |
| Including non-cash compensation in FICA wages | Over-reporting Social Security and Medicare taxes | Farm-provided meals and lodging for farmworkers are generally exempt from FICA (IRC §3121(a)(8)). Exclude these from Lines 4 and 6. |
| Filing Form 941 instead of Form 943 | IRS cross-reference mismatch, potential penalties | Agricultural labor goes on Form 943. Non-ag workers go on Form 941. Both may be filed by the same employer. |
| Misclassifying crew leader responsibilities | Both the farm operator and the crew leader may believe the other is the "employer" — and neither files | Execute a written agreement specifying who is the employer for tax purposes. Absent a written agreement, the crew leader is the employer under IRC §3121(i). |
| Using the wrong lookback period | Incorrect deposit schedule, FTD penalties | Form 943 lookback is the second preceding calendar year, not the four-quarter period used for Form 941. For 2026, look at 2024 Form 943 liability. |
| Failing to file Form 940 for FUTA | FUTA underpayment penalties | Agricultural employers who meet FUTA thresholds must file both Form 943 (FICA/FITW) AND Form 940 (FUTA). These are separate obligations. |

Penalties for Form 943 follow the same IRC provisions as Form 941:

Practitioner Pro Tips
Early in the growing season, estimate whether your total agricultural labor costs will exceed $2,500 for the year. If the answer is clearly yes (which it is for virtually all commercial farms), begin withholding and depositing FICA from the first payroll rather than waiting until the threshold is reached. Retroactive compliance — going back to withhold and deposit FICA on wages already paid — is administratively burdensome, creates cash flow issues with workers who were not expecting the deduction, and increases the risk of deposit penalties. Proactive withholding is the professional approach.
Many farms have highly seasonal payrolls — minimal wages in winter, massive payrolls during planting and harvest. If you are a monthly depositor, your deposit obligations spike during peak months. If you are a semiweekly depositor, your obligations during harvest season can be daily or near-daily. Set up a deposit calendar specifically for peak season, and ensure the person responsible for EFTPS deposits is available (or has a backup) during critical harvest periods. A $100,000 payroll during harvest triggers the next-day deposit rule.
Maintain a separate file for each H-2A worker containing: (1) Copy of the H-2A visa and I-94, (2) Executed employment contract specifying the Adverse Effect Wage Rate (AEWR), (3) Documentation confirming FICA/FITW/FUTA exemption was applied, (4) Copy of Form W-2 issued at year end showing $0 in all tax boxes. In an audit, the IRS will verify that H-2A exemptions were properly applied. Without supporting documentation, the IRS may reclassify these workers as FICA-subject, resulting in assessments of both employer and employee shares of FICA plus penalties.
When setting up agricultural payroll processing in MasterTax™, create distinct worker classification codes: (1) H-2A Temporary Agricultural (FICA exempt, FITW exempt, FUTA exempt), (2) Domestic Seasonal Agricultural (subject to $150/$2,500 thresholds), (3) Year-Round Agricultural (standard FICA/FITW, no special thresholds). Map each classification to the correct tax jurisdiction rules. The system's threshold monitoring for the $150 cash wages and $2,500 total expenditure tests requires proper initial configuration to avoid manual intervention mid-year. Test the configuration with sample data before your first live payroll run.
At year end, agricultural employers should perform a comprehensive cross-form reconciliation: (1) Form 943 total wages + Form 941 total wages (if applicable) should reconcile with aggregate W-2/W-3 totals. (2) Form 940 FUTA wages should reconcile with Form 943 FICA wages minus H-2A exempt wages. (3) The number of W-2s issued should match the sum of Form 943 Line 1 and Form 941 Line 1 (if applicable), adjusted for timing differences. (4) Total deposits per EFTPS should equal Form 943 Line 12 plus Form 941 Line 13a (if applicable) plus Form 940 Line 13. Document this reconciliation and retain it with your tax records — it is your first line of defense in an audit.
