Introduction: What are quarterly tax forms, and what do they do?
Managing federal taxes is a year-round responsibility for small business owners and self-employed individuals. Quarterly taxes refer to the periodic tax obligations that employers and self-employed individuals must meet throughout the year, rather than settling everything at once when filing an annual tax return.
Quarterly taxes can feel harder than they are because the IRS uses several forms for similar but different jobs. If you have employees, you must withhold federal income tax, Social Security, and Medicare taxes from their wages. You are also responsible for paying the employer’s share of these taxes. The IRS requires most businesses to report and remit payroll taxes four times per year, using specific forms tailored to different types of employers.
The three core employer forms are:
- Form 941 (Employer’s Quarterly Federal Tax Return)
- Form 943 (Employer’s Annual Federal Tax Return for Agricultural Employees)
- Form 944 (Employer’s Annual Federal Tax Return)
Self-employed individuals and those with income not subject to withholding also have a quarterly obligation through Form 1040-ES (Estimated Tax for Individuals).
In this guide, we’ll explain which form applies to your business and when to pay, helping you prevent costly penalties and keep your tax bill predictable.

Quarterly tax obligations overview
Understanding how to pay quarterly taxes starts with knowing your specific obligations. As an employer, you act as a tax collector for the federal government. Every time you run payroll, you must withhold specific amounts based on each employee’s W-4 form. You then deposit these funds, along with your own employer contributions, on a regular schedule.
Your reporting frequency depends on the total tax you expect to owe. For most businesses, this means filing Form 941 every three months. However, the IRS allows exceptions for agricultural employers and very small businesses to reduce their paperwork burden. By tracking your payment history and understanding estimated tax requirements, you can stay compliant and avoid underpayment penalties
Who pays quarterly payroll taxes?
Any business that pays wages to employees is generally required to file quarterly payroll taxes. This includes:
- corporations
- partnerships
- sole proprietors
- nonprofit organizations
If you have no employees but earn self-employment income — for example, as a freelancer, independent contractor, or small business owner — you are still responsible for making estimated tax payments on that income throughout the year.
Using pdfFiller helps you organize your tax year efficiently. You can store your completed forms in a secure, encrypted account. This makes it easy to review past payment periods and ensure you have accurate records when it is time to file your annual tax return.
What is Form 941, and who must file it?
Form 941 Employer’s Quarterly Federal Tax Return is the standard document used to report income taxes, Social Security tax, and Medicare tax withheld from employee paychecks. Most employers must file this form every quarter.
Here’s what Form 941 reports:
- wages paid to employees,
- federal income tax withheld,
- the employee and employer shares of Social Security and Medicare tax,
- certain related payroll tax adjustments or credits when applicable.
When is Form 941 due?
The Form 941 due dates follow a simple pattern: the return is due by the last day of the month after each quarter ends. That means April 30, July 31, October 31, and January 31, unless the due date falls on a weekend or legal holiday, in which case the next business day applies. If deposits were made on time and in full, the IRS allows additional filing time in some cases.

When should I use Form 943 for agricultural employers?
Form 943 is specifically designed for agricultural employers. If you operate a farm and pay wages to farmworkers, you must use this form instead of Form 941. Unlike Form 941, Form 943 is an annual return, not a quarterly one, to accommodate the seasonal nature of agricultural work. However, you must still make payroll tax deposits throughout the year based on your tax liability using the electronic federal tax payment system.
The IRS says employers who paid wages to agricultural employees subject to federal income tax withholding or Social Security and Medicare taxes must file Form 943. The IRS threshold is also important. Farm wages are subject to these taxes if:
- you pay a single worker $150 or more in cash wages, or
- you pay $2,500 or more in total wages to all farmworkers for the year.
While some hand-harvest workers are exempt, this rule often applies to small agricultural operations.
When are Form 943 tax payments due?
Even though Form 943 is annual, payments may still happen throughout the year. If total employment taxes exceed $2,500, the employer must generally make electronic deposits during the year, and the lookback period determines whether those deposits follow a monthly or semiweekly schedule.
Managing farm payrolls is demanding enough without having to wade through complex paperwork. With pdfFiller, you can easily access the current year’s Form 943 and complete it from your office or in the field. You save time and reduce errors by keeping all your agricultural tax documents in one centralized, secure location.
The IRS Form 943 for the 2025 tax year (Page 1), designed for agricultural employers to report annual payroll taxes, is shown in the pdfFiller editor.
What is Form 944, and who qualifies for it?
The IRS created Form 944 to ease the filing burden on small business owners. It’s designed for employers whose annual liability for Social Security, Medicare, and withheld federal income taxes is $1,000 or less. That threshold determines who may be assigned to Form 944, but it does not mean every 944 filer can always wait until year-end to pay. According to the IRS Form 944 instructions, if total taxes for the year are less than $2,500, the employer can usually pay with the return. If liability exceeds $2,500, deposits are generally required during the year.
Form 941 vs. Form 944: what’s the difference?
The difference between 941 and 944 is one of the most misunderstood payroll tax issues for small business owners. Form 941 is the regular quarterly return for most employers. Form 944 is an annual return designed for the smallest employers, but you can only file it if the IRS gives you written notice that you are part of the Form 944 program.
The primary benefit in the 941 vs. 944 comparison is that Form 944 allows you to report your employment taxes annually instead of quarterly.
941 vs 944: a quick comparison
| Feature | Form 941 | Form 944 |
|---|---|---|
| Filing frequency | Quarterly | Annually |
| Typical filer | Most employers | Small employers (≤$1,000 annual liability) |
| IRS notification required | No | Yes |
| Deposit schedule | Monthly or semi-weekly | Annual (if liability ≤ $2,500/year) |
You cannot simply choose to file Form 944. The IRS will notify you in writing if you are eligible to use this form. If you do not receive a notification, you must continue filing Form 941. Even if you file annually, you might still need to make deposits during the year if your tax liability grows.
When you receive the green light to use Form 944, filling it out takes only minutes with pdfFiller. You can access the document from any device, complete the necessary fields, and maintain a pristine digital copy for your records.
How do I manage Form 1040-ES for estimated individual taxes?
Form 1040-ES is used to figure and pay estimated taxes for individuals. If you earn income that is not subject to withholding—such as self-employment income, rental income, or capital gains—you likely need to make estimated tax payments. This form is typically used to pay income and self-employment taxes by:
- Sole proprietors
- Independent contractors
- Corporate shareholders.
The IRS requires you to pay taxes as you earn or receive income throughout the year. If you expect to owe $1,000 or more when you file your tax return, you must make quarterly estimated tax payments. Form 1040-ES includes a worksheet to help you calculate your adjusted gross income, taxable income, and total tax for the year. It also includes estimated tax vouchers to mail with your payments if you do not pay electronically.
What are the payment schedules and deadlines?
Knowing when quarterly payroll taxes are due is critical for compliance:
- Form 941: The quarterly tax deadlines are April 30, July 31, October 31, and January 31. These dates cover the first, second, third, and fourth quarters, respectively. If a due date falls on a weekend or a legal holiday, your return is due the next business day.
- Form 1040-ES: The deadlines for estimated quarterly tax payments are typically April 15, June 15, September 15, and January 15 of the following year.
- Form 943 and Form 944: Agricultural and small employers generally must file by January 31.
Making timely payments ensures you do not incur additional fees.
How often do you deposit quarterly payroll taxes?
Deposit timing is a separate issue. For Forms 941 and 944, the amount of taxes you reported during the lookback period determines if you’re a monthly or semiweekly depositor. Monthly depositors must deposit employment taxes by the 15th of the following month. For semiweekly depositors, the deadline depends on the payday.
For agricultural employers who file Form 943, the deposit schedule is also based on a lookback period. If you reported $50,000 or less in taxes during that period, you’re a monthly depositor. If you reported over $50,000, you must deposit semiweekly.
For Form 1040-ES, the four payment periods aren’t equal quarters. The IRS sets the following payment periods and due dates:
- Jan. 1 to March 31 (Due April 15)
- April 1 to May 31 (Due June 15)
- June 1 to Aug. 31 (Due Sept. 15)
- Sept. 1 to Dec. 31 (Due Jan. 15 of the following year)
Many self-employed taxpayers are caught off guard because the second and third payment periods are shorter than three months.
How do I calculate estimated quarterly tax payments for a small business?
Learning how to calculate quarterly taxes for small business operations requires estimating your expected adjusted gross income, taxable income, taxes, deductions, and credits for the year. You can use your prior year’s tax return as a starting point. If this is your first year in business, you will need to estimate your income and expenses as accurately as possible.
A simple way to plan your estimated taxes:
- Start with last year’s tax return and current-year income forecast.
- Estimate this year’s taxable income, including self-employment income, investment income, rental income, and other income not covered by withholding.
- Estimate your total tax, including federal income tax and self-employment tax where applicable.
- Subtract expected withholding and refundable credits.
- Divide the remaining amount by the number of payment periods left in the tax year, unless your income is uneven and you need annualized or unequal payments.
How do I use EFTPS and other payment methods?
The IRS offers several ways to pay estimated taxes and payroll tax deposits, ranging from fully electronic to paper-based options.
EFTPS: The Electronic Federal Tax Payment System
The Electronic Federal Tax Payment System (EFTPS) is the IRS’s free online payment portal for businesses and individuals. Employers use EFTPS to make payroll tax deposits, and self-employed individuals use it to submit quarterly estimated payments. EFTPS maintains a full payment history so you can verify that deposits were received.
To use EFTPS, you must enroll at eftps.gov and allow several days for your PIN to arrive by mail. Once enrolled, you can schedule payments up to 365 days in advance, which makes it easy to set quarterly estimated tax payments automatically and avoid missing a deadline.
Other payment options
- IRS direct pay — A free tool for individuals to pay directly from a bank account, suitable for estimated tax payments using Form 1040-ES payment vouchers.
- Credit or debit card — Available through IRS-approved third-party processors, though processing fees apply.
- Check or money order — Mail with a completed payment voucher from Form 1040-ES or the applicable employer form. Make checks payable to “United States Treasury.”
- Electronic Funds Withdrawal (EFW) — Available when filing electronically through tax software.
For most employers, EFTPS is the most reliable method, especially given the strict timing requirements for payroll tax deposits.
What are the penalties for underpayment?
The IRS imposes an estimated tax penalty if you do not pay enough tax throughout the year. According to the IRS requirements, you must pay at least 90% of your current year’s tax liability or 100% of the prior year’s tax liability to avoid penalties. If your adjusted gross income exceeds certain thresholds, you may need to pay 110% of the prior year’s tax. If your income is uneven throughout the year due to things like seasonal work or bonuses, you may be able to use the annualized installment method to adjust your payments and avoid penalties.
If your employer withholds taxes from a primary job, that counts toward your total payments. However, if a portion of your income remains unpaid due to side gigs or investments, the underpayment penalty applies to the shortfall. The IRS calculates the penalty based on how much you underpaid and how long the taxes owed were overdue.

FAQ
1. Do all employers file Form 941?
No. Most employers file Form 941, but agricultural employers generally file Form 943, and some very small employers file Form 944 if the IRS gives written approval. The right form depends on the type of wages paid and the filing program assigned to the employer.
2. Can I choose Form 944 instead of Form 941 on my own?
Usually no. The IRS says Form 944 cannot be filed unless you receive written notice that you are eligible, although an employer may contact the IRS to request the annual filing program. Until that happens, most new employers file Form 941.
3. What is the difference between Form 941 and Form 944?
Form 941 is filed quarterly by most employers to report wages and payroll taxes. Form 944 is filed annually and is reserved strictly for very small employers with an annual tax liability of $1,000 or less. You must receive written IRS approval to use Form 944 instead of Form 941.
4. Who is required to make estimated tax payments?
You must make estimated payments if you expect to owe at least $1,000 in federal tax for the year. This commonly applies to freelancers, independent contractors, and small business owners with self-employment income. Investors receiving substantial capital gains or rental income also fall under this requirement.
5. How do I calculate my quarterly estimated taxes?
Start by estimating your total income, deductions, and credits for the current tax year. Use the worksheet provided in Form 1040-ES to figure your expected tax liability. Divide your total estimated tax by four to determine the amount due each quarter.
6. Can I pay my quarterly taxes online?
Yes, paying online is the most secure and efficient method recommended by the IRS. Businesses should use the Electronic Federal Tax Payment System (EFTPS) to make payroll tax deposits. Individuals can use EFTPS, IRS Direct Pay, or approved credit/debit card processors.
7. What happens if I miss a quarterly tax deadline?
Missing a deadline usually results in an estimated tax penalty for late payment. The penalty amount depends on how much you owe and how many days the payment is late. To stop additional fees from accruing, you should pay the overdue amount as quickly as possible.
8. How does pdfFiller help with tax preparation?
With pdfFiller, you can easily fill out IRS tax forms online by typing directly into the fillable fields — no printing required.

9. What are payroll tax deposits?
Payroll tax deposits are the funds you submit to the government covering the federal income tax, Social Security, and Medicare taxes withheld from employee paychecks. Employers must also include their matching portion of Social Security and Medicare taxes. These must be deposited electronically on a semi-weekly or monthly schedule.
10. Does a refund from last year count toward this year's estimated taxes?
Yes, you can choose to apply all or part of your prior year's tax refund to your current year's estimated taxes. When you file your annual tax return, simply indicate how much of the refund you want applied. This reduces the amount you need to pay out of pocket for your first quarterly installment.
11. What if my income fluctuates during the year?
If your income is uneven, you can use the annualized income installment method to calculate your payments. This method allows you to adjust your quarterly payments based on the actual income earned during each period.
