What payroll taxes does a small business owe, and which forms does it file?

It depends on the actual working relationship, not on what the agreement calls it. The IRS looks at three categories: behavioral control, financial control and the relationship of the parties. Employees go through payroll and get a W-2. Independent contractors don't, and you issue a Form 1099-NEC when the rules require it.

What the IRS weighs:

• Behavioral control: Do you dictate how, when and where the work is done, or train the worker?
• Financial control: Does the worker have their own tools and expenses, work for others, and face a real chance of loss?
• Relationship: Is there a written contract, are there benefits, and is the work an ongoing part of your core business?

If it's unclear, you can ask the IRS for a determination on Form SS-8. If you treated an employee as a contractor without a reasonable basis, you owe the employer taxes you skipped. If you find a past misclassification, the Voluntary Classification Settlement Program (Form 8952) may be worth a look. For contractor thresholds and deadlines, see our guide: Form 1099-NEC: who has to file it? (yclcpa.com/1099nec)

From the employee: federal income tax (based on the W-4), NC income tax (based on the NC-4) and the employee's share of Social Security and Medicare. From the employer: a matching share of Social Security and Medicare, FUTA and NC unemployment insurance.

One point matters more than the rest: the income tax and FICA you withhold is the employee's money held in trust. If it isn't paid over, the IRS can assess the Trust Fund Recovery Penalty, equal to 100% of the unpaid trust fund taxes, against the individuals responsible for paying it.

It depends on your lookback period. For 2026 that's July 1, 2024 through June 30, 2025. If your taxes in that period were $50,000 or less, you're a monthly depositor and deposit by the 15th of the next month. Above $50,000, you're a semiweekly depositor and deposit based on each payday. The rules set your schedule. You don't choose it.

Read from the top; follow the first row that fits. The $100,000 side rule below applies on any day.

Your situation	Schedule	When to deposit
Form 941 tax liability under $2,500 for the current or prior quarter, with no $100,000 day this quarter	Pay with the return	No separate deposit needed
Not the row above, and taxes in the lookback period (July 1, 2024 to June 30, 2025) not more than $50,000	Monthly	Deposit each month's taxes by the 15th of the following month
Not the first row, lookback taxes more than $50,000, Wednesday, Thursday or Friday payday	Semiweekly	By the following Wednesday
Not the first row, lookback taxes more than $50,000, Saturday through Tuesday payday	Semiweekly	By the following Friday

Side rule: $100,000 or more accumulated on any day

Situation	What to do
$100,000 or more accumulated on any day	Deposit by the next business day
You were a monthly depositor	You become semiweekly from that day for the rest of the year and the next year

Details that trip people up:

• Deposits are electronic only: EFTPS, IRS Direct Pay or the IRS business tax account. With EFTPS, schedule the payment by 8 p.m. Eastern the day before the settlement date.
• Your deposit schedule and your return are separate questions. Most employers file Form 941 quarterly. Small employers the IRS notifies can file Form 944 annually. Pick the wrong form when you deposit and the payment lands on a return you don't file.
• December payroll deposited on January 15 still belongs to the prior year's fourth quarter, not the new year's first quarter.
• FUTA has its own rule. If the quarter's FUTA is $500 or less, carry it forward. Once it's over $500, deposit by the last day of the month after the quarter ends.

Form 941 every quarter (April 30, July 31, October 31 and January 31). Form 940 (FUTA) and Forms W-2 / W-3 every year. 2026 W-2s are due to employees, and to the Social Security Administration with Form W-3, by February 1, 2027, whether you file on paper or electronically.

• Form 941 reports the quarter's wages, income tax withheld and FICA, and has to tie to the quarter's deposits.
• Form 940 is filed once a year, due January 31 and pushed to the next business day on a weekend (the 2025 return was due February 2, 2026). If all FUTA was deposited on time, you get 10 extra days.
• W-2 / W-3: If you file 10 or more information returns in total for the year (W-2s, 1099s and so on), all of them must be filed electronically.
• New for 2026 W-2s: Box 12 adds code TP (cash tips reported to the employer), TT (qualified overtime) and TA (employer Trump account contributions), and Box 14 splits into 14a and 14b. The "no tax on tips or overtime" rules are income tax deductions for employees. They don't remove Social Security or Medicare, so FICA is still withheld.

Two agencies are involved. The NC Department of Revenue (NCDOR) handles income tax withholding (NC-5, NC-5P, NC-3), and the Division of Employment Security (DES) handles unemployment insurance (NCUI 101). New hires also have to be reported to NC New Hires within 20 days.

Your NC withholding schedule depends on average monthly withholding (2026 NC-30 rules):

• Under $250 a month: quarterly NC-5, due the last day of the month after the quarter.
• $250 to under $2,000 a month: monthly NC-5, due the 15th of the next month. December's return is due January 31.
• $2,000 or more a month: semiweekly. Pay with Form NC-5P on the same day as your federal deposit and file Form NC-5Q each quarter (due with Form 941, or 10 days later if every payment was on time). NC does not follow the federal $100,000 next-day rule.
• No withholding still means a return. A zero return has to be filed.

Also on the list:

• NC-3 annual reconciliation: Due January 31 (next business day on a weekend), filed electronically through eNC3 with the state copies of W-2s and 1099s. Late filing costs $50 a day up to $1,000, and not filing electronically as required costs $200.
• NCUI 101: Quarterly unemployment wage and tax report, due April 30, July 31, October 31 and January 31. For 2026, the first $34,200 of each employee's wages is taxable, new employers pay 1.0%, and later rates come from your DES rate notice (0.06% to 5.76% for experienced employers).
• New hires: Collect the federal W-4, the NC-4 (or NC-4 EZ / NC-4 NRA) and Form I-9. Report to NC New Hires within 20 days, including rehires who were separated for 60 days or more.
• Employees claiming exempt on Form NC-4 EZ must refile every year. Starting February 16, anyone who hasn't is withheld as Single with zero allowances.

Yes. A shareholder who works in the business has to take reasonable compensation before taking distributions. If you only take distributions, the IRS can reclassify them as wages and assess Social Security and Medicare tax.

The IRS doesn't set a percentage or dollar amount. It looks at factors such as training and experience, duties, time devoted to the business, dividend history, what non-shareholder employees are paid, and what comparable businesses pay for similar work. So the salary should fit your facts, and the reasoning should be documented. For where to form your company and whether an S election makes sense, see our formation guide (yclcpa.com/llc).

Deposits follow your pay schedule all year. The end of the month after each quarter is when Forms 941, NCUI 101 and quarterly NC-5s are due. Late January is the busiest stretch, when the annual filings pile up.

Read from the top in date order; each row is what is due by that date.

Date	What is due	Note
15th of each month	Federal deposit (monthly depositors) and monthly NC-5	—
Jan 15	Deposit for December 2025 payroll	Still 2025 Q4
Apr 30	Q1 Form 941, NCUI 101, quarterly NC-5	—
Jul 31	Q2 Form 941, NCUI 101, quarterly NC-5	—
Oct 31	Q3 Form 941, NCUI 101, quarterly NC-5	—
End of January 2027	Q4 Form 941, NCUI 101, quarterly NC-5, December's monthly NC-5, Form 940, Forms W-2 / W-3 and NC-3	January 31 is a Sunday, so February 1

Also

• Semiweekly depositors deposit by payday. NC semiweekly filers pay with NC-5P on the federal deposit date and file NC-5Q quarterly.
• Deadlines that fall on a weekend or legal holiday move to the next business day.

Set up the rules first, then run them every period. If something has gone wrong, reconcile before you fix it, and don't guess at a penalty amount on your own.

• Situation A: Hiring your first employee. Decide employee vs. contractor. Collect the W-4, NC-4 and I-9 before the first day and report the hire to NC New Hires within 20 days. Confirm your federal and NC withholding and unemployment accounts are open. Set the pay schedule and map out each deposit date.
• Situation B: An S corporation with just the owner. Set a reasonable salary based on your duties, hours and what similar roles pay, and document the reasoning. That salary runs through the full set of Forms 941, 940, W-2, NC-5 and NCUI 101, and the remaining profit comes out as distributions.
• Situation C: Late deposits, missed filings, or a letter in the mail. Match every deposit confirmation against Forms 941, NC-5 and NCUI 101, month by month, to see whether something is truly unpaid or paid but never recorded. Then make up the deposits and filings and respond to the notice. Penalties step up the longer it goes, so the sooner the better.
