North Carolina SUI: Employer Rates, Wage Base, and Filing

If you pay wages for work performed in North Carolina, you likely owe North Carolina SUI tax — the state unemployment insurance tax administered by the Division of Employment Security. Employers pay it alone; nothing comes out of employee wages. For 2026, rates run from 0.06% to 5.76% on the first $34,200 each employee earns during the year, and new employers start at a flat 1%.¹ Reports and payments are filed quarterly through NCSUITS, the state’s online tax system.

Who Has to Pay

North Carolina ties liability to the federal FUTA standard: if your business is a FUTA employer, you owe state unemployment tax on North Carolina wages.² For most businesses, that means you become liable once you pay $1,500 or more in wages in any calendar quarter, or once you employ at least one person for any part of a day in 20 different weeks in a year. Those weeks don’t have to run consecutively.

Two categories have different thresholds. Agricultural employers become liable at $20,000 in cash wages in a quarter or 10 workers in 20 weeks. Household employers — think nannies, housekeepers — cross the line at $1,000 in cash wages in a quarter. Once you meet a threshold, liability reaches back to the start of that period, so a late registration can produce back-assessed tax with interest and penalties.

Registering With DES

File the Employer Status Report, Form NCUI 604, within 10 days of becoming a liable employing unit.³ The clock starts the day you first pay wages for work in North Carolina, not at the end of the quarter. You can complete the form through the NCSUITS portal or download it from the DES website.⁴

You’ll need your FEIN, the legal name and both physical and mailing addresses for the business, the exact date wages were first paid, a description of what the business does and its entity type, and the names and Social Security numbers of all owners, general partners, or principal corporate officers. Errors on the initial filing — a wrong start date, a missing officer — slow the account setup and can affect the rate DES assigns you.

The 2026 Wage Base

SUI tax applies only to the first $34,200 of wages you pay each employee in 2026.⁵ Once an employee’s year-to-date earnings pass that cap, the rest of their wages for the year are exempt. The cap resets every January 1 for each employee.

How DES Sets Your Rate

DES mails an annual tax rate notice in late fall or early winter. For 2026, rates fall between 0.06% and 5.76%.⁶ Where you land depends on how long you’ve been an employer and what your account looks like.

New Employer Rate

New employers pay 1% until the account has been chargeable with benefits for at least 12 calendar months ending July 31 before the computation date.⁵ Functionally, that means four reported quarters spanning two consecutive calendar years. After that, DES moves you onto experience rating.⁷

Experience Rating

Experience rating works like insurance pricing. The more unemployment benefits former employees collect against your account, the higher your rate climbs. DES calculates a reserve ratio — your account balance divided by taxable payroll over the prior 36 months ending June 30 — then multiplies it by 0.68 to get your Employer’s Reserve Ratio Percentage (ERRP). Your final rate is a subtraction from one of three base rates (2.9%, 2.4%, or 1.9%), with the base determined by the health of the state’s UI Trust Fund relative to total insured wages.⁶ A positive ERRP pulls the rate down; a negative one pushes it up. Whatever the math produces is capped at 0.06% on the low end and 5.76% on the high end.

The 20% Surtax

When the UI Trust Fund balance drops below $1 billion, a 20% surtax applies to every contributing employer’s payments for that calendar year. The surtax is not FUTA-certified, so during a surtax year only 83.33% of what you pay to North Carolina counts toward your federal FUTA credit. When the fund holds at or above $1 billion, DES certifies 100% of your state contributions.⁵

Lowering or Challenging Your Rate

Two options exist if your assigned rate looks wrong or higher than you’d like.

A voluntary contribution is an extra payment that boosts your account balance, raises your reserve ratio, and can shift you into a lower rate tier. To affect the 2026 rate, the payment had to reach DES by December 17, 2025.⁵ Future-year deadlines post on the DES Tax Rate Information page each fall. You can pay through NCSUITS or by mailing a check marked “voluntary contributions to NCDES.” Once processed, the updated rate appears in your NCSUITS account rather than on a new paper notice.

A protest is the route if you think DES miscalculated. File it before May 1 of the year the rate applies; for 2026 rates, the deadline is April 30, 2026.⁵ Protests go through NCSUITS, by fax, or by mail, and they must be signed by an owner, partner, or corporate officer. A bookkeeper or third-party agent cannot sign for you. Miss the deadline and the rate is final for the year.⁷

Quarterly Filing and Payment

Once registered, you file a Quarterly Tax and Wage Report through NCSUITS.⁸ The report lists each employee’s wages and calculates the tax due. Payment happens in the same session. Due dates fall on the last day of the month after each quarter closes:

Q1 (January–March): due April 30
Q2 (April–June): due July 31
Q3 (July–September): due October 31
Q4 (October–December): due January 31

NCSUITS produces a confirmation receipt at submission. Keep it. If you find errors later, you can amend the wage report directly in the portal. DES retains your reports and adjustments for five years, and they stay available in your account.

Penalties for Late Filing or Payment

Two penalties can hit at once. Filing late costs 5% of the tax due for each month or partial month the report is overdue, capped at 25%. Paying late costs a flat 10% of the unpaid tax. Interest accrues on unpaid contributions from the due date at the rate under N.C. Gen. Stat. § 105-241.21, which changes semiannually. If a late report shows no tax due, no penalty applies unless it stays outstanding more than 30 days.¹⁰

DES can waive penalties in narrow situations, including death or serious illness of the person responsible for filing, destruction of business records by disaster, or DES’s failure to provide requested forms. A report timely mailed to the wrong agency also qualifies for a late-filing waiver.¹⁰

Employee or Independent Contractor

Who counts as an employee drives more assessments than the rate math ever will. Under North Carolina’s Employment Security Law, an independent contractor is someone hired to do work who is not subject to your control over how the work gets done or what happens as it progresses.² Courts weigh whether the worker runs an independent business, brings their own skills and tools, is paid a fixed price rather than an hourly wage, sets their own schedule, can hire helpers, and cannot be fired over the methods they use. No single factor decides it. Directing when, where, and how someone works points toward employee status regardless of what the paperwork calls the relationship. Misclassification exposes you to back tax on the wages you should have reported, plus penalties and interest.

Reimbursable Status for Nonprofits and Government

Section 501(c)(3) nonprofits, government entities, and Indian tribes can skip standard rated contributions and instead reimburse DES dollar-for-dollar for unemployment benefits actually paid to their former workers. The election requires written notice at least 30 days before the January 1 effective date. Newly eligible employers get 30 days from their notification to elect. The commitment binds for at least four years, and ending it also requires written notice 30 days before the next January 1.¹¹

Whether it pays off depends on workforce stability. A stable employer saves money; one large layoff can cost far more than years of standard contributions would have. Reimbursable employers are exempt from the 20% surtax when the trust fund dips below $1 billion.⁵

If You Use a PEO

North Carolina is a PEO-reporting state. A Professional Employer Organization files and pays under its own DES account, so your workers are taxed at the PEO’s rate rather than yours. When you enter a PEO arrangement, suspend or close your existing DES account by filing Form NCUI-101-A, the Change in Status Report, and selecting the option for operating without employees.⁹ Leave the PEO later and you reactivate or reopen your account, typically starting again at the new employer rate.
