You don't choose between Form 941 and Form 944. The IRS does. Your primary federal payroll tax return is assigned based on your estimated annual liability, a figure the IRS reviews and confirms, not a preference you submit. Treating form selection as a free choice is one of the more consequential misunderstandings in payroll tax compliance. Here's how the assignment logic actually works, and what it means once you're running payroll day to day.
The IRS Assigns Your Primary Payroll Tax Return, You Don't Choose It
It's easy to treat Form 941 versus Form 944 as a choice you make: quarterly filing for some, annual for others, pick whichever fits. That framing is backwards. Per IRS Publication 15 and the Form 944 instructions, Form 944 is assigned in writing by the IRS to qualifying small employers, specifically those whose estimated annual employment tax liability is $1,000 or less. You don't self-select into annual filing; the IRS reviews your estimate and sends written notification. Without that notification in hand, your default is Form 941, filed quarterly, regardless of how small your actual liability turns out to be. If you expect to qualify but haven't received notification, you have one correct path: contact the IRS directly to request Form 944 status, wait for the written confirmation, and only then file annually. Filing annually on the assumption of eligibility, without that confirmation in hand, is exactly the kind of gap an IRS review later flags.
This is exactly the kind of verification AsureWorks is built to take on: when Asure specialists manage your payroll tax filings, confirming your IRS-assigned form is part of ongoing service rather than a one-time setup step, and you remain the employer of record throughout, no co-employment involved. That matters more for a growing business than it looks. If you crossed the $1,000 threshold mid-year, added your first few W-2 hires, or simply never had anyone confirm the assignment in writing, you could be filing the wrong form for years without anyone noticing, since a wrong-but-consistent filing pattern doesn't trigger an automatic flag until an audit or a reconciliation catches it.
Form 941 and Form 944 Cover the Same Taxes, the Difference Is Cadence and Eligibility
Both forms report the identical three tax obligations: federal income tax withheld from wages, the employee share of Social Security and Medicare, and the employer share of Social Security and Medicare. The substantive difference is filing cadence and the IRS-assigned eligibility gate that determines which cadence applies to you. If you're a Form 941 filer, you follow the standard monthly or semi-weekly deposit schedule based on the $50,000 four-quarter lookback threshold. If you're a Form 944 filer, you get a real simplification worth knowing about: if your total annual liability stays under $2,500, you can simply pay the balance with your return itself, with no periodic deposits required at all during the year, per IRS Publication 15. If your liability as a Form 944 filer happens to reach $2,500 or more in a given year, you lose that pay-with-return simplification and step into a monthly-or-semiweekly deposit schedule instead, determined against the same $50,000 threshold but measured against your liability in the second preceding calendar year rather than the rolling four-quarter window a 941 filer uses, per IRS Notice 931. That's a detail worth confirming each year, since last year's treatment doesn't automatically carry forward once your liability crosses the line.
One point worth addressing directly: Form 944 is not being discontinued. It remains an active IRS form, updated for each tax year the same way Form 941 is, per the current IRS Form 944 instructions. If you read a claim that Form 944 is being phased out and react by switching to quarterly filing on your own, without securing IRS approval first, you create exactly the kind of unauthorized-switch problem the next section covers, over a rumor with no actual policy change behind it. This is also where a connected system earns its keep: Luna AI, embedded across AsureCentral, is built to flag a deposit-schedule shift for review when your liability crosses the $2,500 threshold, since that kind of change is easy to miss while your attention is elsewhere. 941 and 944 aren't the whole picture, though. Three more federal forms sit entirely outside your primary return, and missing one of them creates its own filing problem.
Three Additional Federal Forms Complete the Employer Payroll Tax Picture
None of them replace your primary return. Form 940 covers FUTA, the Federal Unemployment Tax Act, an employer-only obligation filed annually and entirely separate from FICA (Federal Insurance Contributions Act) and income tax withholding, per the IRS's Form 940 instructions. A common and costly assumption is that filing Form 941 satisfies FUTA too; it does not. Form 940 is a standalone filing requirement if you have FUTA liability, regardless of which primary return you file.
Form 943 covers agricultural employees specifically, an annual filing that's mutually exclusive with Form 941 for the same employee population. If you pay a farmworker cash wages of $150 or more in a year, or $2,500 or more in total wages across all farmworkers, you file Form 943 for those workers instead of Form 941, per the IRS's Topic 760 on agricultural employer requirements. Form 943's deposit schedule doesn't follow Form 941's four-quarter lookback. It uses the same second-preceding-calendar-year lookback mechanism Form 944 uses: your deposit schedule is set by your total Form 943 liability from two years prior, not a rolling four-quarter window, per IRS Notice 931. If your business has both a farm operation and a non-agricultural side, a landscaping company with a small nursery operation, for example, you end up filing Form 941 for your non-agricultural staff and Form 943 for your farmworkers in the same year, tracking two separate wage populations against two separate forms, on two separate lookback mechanisms, rather than combining them into one filing.
Form 945 covers nonpayroll withholding, pensions, annuities, and backup withholding among them, filed annually and kept entirely separate from wage-based withholding. The deposit rule here is easy to miss and expensive to get wrong: Form 945 deposits must never be combined with Form 941, 943, or 944 deposits, per the IRS's Form 945 instructions; each pool of withheld tax has to be tracked and deposited on its own. This is where a connected platform matters: AsureCentral keeps FUTA, agricultural wage, and nonpayroll withholding obligations visible in the same system as your primary return, rather than scattered across separate spreadsheets or disconnected tools where one of them is easy to lose track of. If you'd rather hand that tracking to someone else entirely, AsureWorks specialists manage these filings directly while you remain the employer of record throughout. Knowing all five forms is only the foundation, though. Circumstances change, and eventually a form switch between 941 and 944 might become worth considering, a process with its own strict rules.
Switching Between 941 and 944 Requires IRS Approval, and the Window Is Narrower Than Expected
If you want to switch from Form 941 to Form 944, or back, you cannot simply start filing the other form. The request has to go to the IRS by a specific deadline: a written request postmarked by March 15 of the tax year, or a phone request by April 1, and the IRS confirms the change in writing before it takes effect, per the IRS's guidance on filing employment taxes annually. If you switch on your own, without that confirmation, you risk deposits being misapplied against the wrong filing cadence, which the IRS can treat as a failure-to-deposit issue even when the underlying tax was paid.
The March 15 deadline arrives earlier in the calendar year than most payroll planning cycles account for, since it falls well before your prior-year close is likely finished. A written request has to be postmarked by that date; a phone request to the IRS extends the window slightly, to April 1, but both routes end the same way, with the IRS mailing written confirmation before the new filing cadence actually takes effect. Filing under the new form before that confirmation arrives, even with a request already submitted, is itself a version of the unauthorized-switch problem this section opened with. If a switch is genuinely warranted, this is exactly the kind of deadline-driven task AsureWorks specialists take on as part of managing your payroll tax filings, submitting the request and confirming IRS approval before any change in cadence takes effect, so it doesn't get lost while your attention is on year-end reconciliation instead. None of this is intuitive if you inherited your payroll setup from someone else rather than confirming it yourself, which is exactly where the next risk shows up.
The Employers Most at Risk Inherited a Filing History They Didn't Set Up
If you're a growth-stage employer who acquired a business, switched payroll providers, or brought payroll in-house mid-year, you frequently inherit a filing form assignment you never personally confirmed. Your risk runs two directions: continuing to file the same form because that's what the prior setup did, without verifying it against the IRS's actual assignment on record, or switching because a new provider's system defaults to a different form, without securing IRS approval first.
There's a year-end consequence that makes this more than a filing-mechanics question: the totals reported on your employees' W-2s have to reconcile against the totals reported across every 941 or 944 filing you make for the year. A form-type mismatch, filing 941 for part of the year and 944 for the rest without IRS authorization for the switch, compounds into a W-2 reconciliation discrepancy at year-end, on top of the underlying filing error. This is one advantage of AsureWorks's no-co-employment model: because you remain the employer of record throughout, moving your payroll to Asure's specialists doesn't introduce a new employer identity for the IRS to reconcile against, which is one fewer variable to untangle when a prior provider's assumption is what needs sorting out.
Bottom Line
The IRS assigns your payroll tax return. Treating form selection as discretionary is the root cause behind most misfiling risk in this category, whether that shows up as an unauthorized 941-to-944 switch, a missed Form 940 filing alongside a primary return that only covers FICA and income tax, or a Form 945 deposit combined with wage-based withholding it was never supposed to touch. Here's how the five forms break down at a glance:
| Form | Covers | Threshold/Eligibility | Filing Cadence |
|---|---|---|---|
| 941 | Federal income tax withholding + FICA (Social Security and Medicare) | Default filing unless the IRS assigns Form 944 in writing | Quarterly |
| 944 | Same taxes as Form 941 | IRS-assigned when estimated annual liability is $1,000 or less | Annually |
| 940 | FUTA (federal unemployment tax) | Applies to any employer with FUTA liability | Annually |
| 943 | Federal income tax withholding + FICA, agricultural employees | $150+ cash wages to one farmworker in a year, or $2,500+ total farmworker wages | Annually |
| 945 | Nonpayroll withholding (pensions, annuities, backup withholding) | Applies whenever nonpayroll withholding occurs | Annually |
If you've never confirmed your form assignment in writing from the IRS, that's the first thing to verify, well before your next filing deadline instead of waiting for a notice to force the question. Audit your current filing form against the IRS's assignment on record, confirm your 940, 943, and 945 obligations are each being met as their own separate filing, and if a form switch is genuinely warranted, start the request early enough to clear the March 15 deadline. AsureCentral and AsureWorks both build this verification into how your payroll gets set up and maintained, whether you run payroll yourself or have Asure's specialists run it, so getting the underlying assignment right happens once, at setup, instead of getting discovered later at an audit or a W-2 reconciliation. If you're not sure where your own filing stands, start by pulling your last IRS notice on file and checking it against what you're actually filing today, or talk to Asure about moving that verification into AsureCentral or AsureWorks before your next deadline forces the question.
Related Questions
How do I know if I need to file Form 941 or Form 944?
Form 944 is assigned by the IRS in writing to employers whose estimated annual employment tax liability is $1,000 or less; it's never self-selected. If you haven't received that written notification, you file Form 941 quarterly by default, regardless of how small your actual liability turns out to be. If you expect to qualify for Form 944 but haven't been notified, you can request it directly from the IRS rather than assuming eligibility. If you're an AsureCentral or AsureWorks client, this confirmation is part of what gets verified when your payroll tax filings are set up, not something left for you to track down later.
Can I switch from Form 941 to Form 944?
Yes, but only with IRS approval. Submit a written request postmarked by March 15 of the tax year, or call the IRS by April 1, and wait for written confirmation before filing under the new form. Switching without that confirmation risks deposits being misapplied against the wrong schedule, which can trigger failure-to-deposit exposure even when the tax itself was paid.
Is Form 944 being discontinued?
No. Form 944 remains an active IRS form, updated for each tax year the same way Form 941 is. The eligibility threshold, $1,000 or less in estimated annual employment tax liability, is unchanged, and the IRS continues to assign the form in writing to qualifying small employers.
What is the difference between Form 940 and Form 941?
Form 940 covers FUTA, an employer-only tax that funds federal unemployment insurance, filed annually and entirely separate from the taxes Form 941 covers. Form 941 (or Form 944, if assigned) covers federal income tax withholding and FICA. These are always two separate obligations; filing one does not satisfy the other.
What is Form 943 and who files it?
Form 943 is the annual federal tax return for agricultural employees. It applies if you pay a farmworker $150 or more in cash wages in a year, or $2,500 or more in total wages across all farmworkers. It's mutually exclusive with Form 941 for that same employee population, and its deposit schedule follows the same second-preceding-calendar-year lookback Form 944 uses, not Form 941's rolling four-quarter window.
Do I need to file both Form 940 and Form 941?
Yes, if you have FUTA liability and employees subject to income tax withholding and FICA, you need both. Satisfying one filing requirement doesn't satisfy the other; they report entirely different taxes on entirely different schedules. A narrow set of exemptions, including certain nonprofit and government employers, can remove FUTA liability specifically, and that exemption has to be confirmed on its own, since Form 941 filing status alone doesn't establish it either way. AsureCentral keeps both obligations visible in the same connected system, so satisfying one doesn't create a false sense that the other is covered.
