North Dakota Payroll Tax Requirements & Rates | Essential Guide for Employers

Employers in North Dakota face unique payroll tax requirements that demand attention to detail and precision. Keeping up with state-specific obligations, like income tax withholding and unemployment insurance, is a necessary part of managing payroll effectively. Compliance isn't just about following rules—it's about ensuring smooth operations and avoiding penalties.

North Dakota's payroll taxes come with specific processes and filing guidelines that employers must navigate. From registering accounts to calculating withholding amounts, the steps are straightforward but require accuracy. Staying informed on state regulations helps employers avoid common errors and ensures employees are paid correctly.

This guide focuses on North Dakota state payroll taxes, including income tax withholding and state unemployment insurance (SUI). Federal payroll taxes such as FICA and FUTA apply as usual, but the emphasis here is on the state-level responsibilities employers need to manage.

Understanding North Dakota Payroll Taxes

Employers in North Dakota are responsible for two primary state payroll taxes: income tax withholding and SUI. These state requirements are in addition to federal taxes like Social Security, Medicare, and federal unemployment.

North Dakota income tax withholding applies to employees working within the state if their wages are subject to federal withholding. Employers use federal Form W-4 data to calculate state income tax and must register for an income tax withholding account through the North Dakota Taxpayer Access Point (ND TAP). The state also requires electronic filing of withholding returns and wage statements, such as W-2s and 1099s, through ND TAP or compatible accounting software. Employers should note that supplemental wages, such as bonuses or commissions, are treated consistently with federal withholding rules.

Employers must also manage SUI, which funds unemployment benefits for eligible workers. Registration for an SUI account is required, and employers report employee wages quarterly. The tax rate for state unemployment insurance depends on factors including the employer's industry and unemployment claims history. Regular reporting and payments are essential to maintain compliance and avoid penalties.

North Dakota Income Tax Withholding

Employers paying wages to employees for work performed in North Dakota must withhold state income tax if those wages are subject to federal withholding. This requirement ensures accurate tax collection for employees working within the state. Additionally, North Dakota-based employers must withhold state income tax from residents working in other states—unless those states require withholding for the wages earned.

Exemptions

Some wages are not subject to North Dakota income tax withholding. For example, wages paid by farmers or ranchers are exempt, as are wages specifically excluded from federal income tax withholding. Knowing these exemptions helps employers avoid unnecessary withholdings and ensures accurate reporting.

Federal Form W-4 Use

North Dakota uses employee information from the federal Form W-4 to calculate proper state income tax withholding. The form's details, such as filing status and dependents, guide employers in determining withholding amounts.

For employees who submitted a W-4 form dated before 2020, calculations follow the older system based on allowances. Employees with a newer W-4 (2020 or later) use income adjustments and specific dollar amounts instead. Employers need to account for the W-4 version provided and apply the correct calculation method to avoid withholding errors. Accurate application of W-4 data ensures employees' tax obligations are met without over- or under-withholding.

Calculating State Withholding

North Dakota state payroll taxes require precise calculations to ensure compliance and accuracy. Employers determine withholding amounts by following a clear, structured process that accounts for gross wages, pre-tax deductions, and state-specific tax rates. Every step matters to avoid payroll discrepancies and ensure employees' tax obligations are met.

Annualizing Method

The annualizing method breaks down withholding calculations into manageable steps:

1. Identify the employee's gross wages for the pay period.

2. Subtract pre-tax deductions such as retirement contributions or health insurance premiums.

3. Multiply the adjusted wages by the number of pay periods in the year to calculate the annualized income.

4. Match the annualized income to the appropriate withholding table based on the employee's filing status and W-4 version.

5. Divide the calculated annual withholding by the total pay periods in the year to determine the per-paycheck withholding. Round to the nearest dollar.

This approach standardizes withholding across pay periods and ensures consistency with annual income levels.

Tax Tables

North Dakota's tax tables use progressive rates, ranging from 1.95% for lower earnings to 2.5% for higher income brackets. The employee's filing status and taxable income determine the specific rate. Separate tables are available for single, married, and head-of-household filers to accommodate different tax scenarios.

Employers should refer to the correct table based on the employee's W-4 submission. Filers using W-4 forms from before 2020 may require alternate calculations, but the resulting withholding amount adheres to the same state rates. Always confirm tax table updates annually to ensure compliance.

Supplemental Wages

North Dakota treats bonuses, commissions, and overtime as supplemental wages. Employers calculate withholding differently depending on how these payments are issued:

• Separate Payments: If supplemental wages are paid independently of regular wages, calculate withholding based solely on the supplemental amount using the annualizing method.

• Combined Payments: When supplemental wages are included with regular pay, calculate withholding based on the total combined amount.

Handling supplemental wages correctly ensures accurate tax withholding and simplifies reporting for both employers and employees.

Unemployment Insurance Requirements

North Dakota requires most employers to pay state unemployment insurance (SUI) taxes to support workers who become unemployed through no fault of their own. The tax structure is straightforward but varies depending on employer classification and payroll history.

Who Pays SUI

For-profit employers are generally responsible for SUI contributions. Some exceptions apply, including specific farm operations and qualifying nonprofit organizations. Employers should confirm their status under state guidelines to determine tax obligations.

Wage Base

Each year, North Dakota sets a taxable wage base for SUI. For 2025, the wage base is $45,100. Employers calculate SUI taxes only on the first $45,100 of each employee's wages. Any earnings exceeding this amount are exempt from additional SUI taxation.

Rates for New vs. Established Employers

Newly registered employers receive a standard SUI tax rate, often tied to their industry classification. Established employers are assigned a rate based on their experience rating, which reflects past unemployment claims and contributions. A positive claims history typically results in a lower tax rate, making accurate tracking and reporting important for reducing long-term costs.

Filing and Payment Frequency

SUI taxes are reported and paid quarterly. Deadlines fall at the end of the month following each calendar quarter:

• Quarter 1: April 30

• Quarter 2: July 31

• Quarter 3: October 31

• Quarter 4: January 31

Employers must submit a detailed report of total wages, taxable wages, and the amount owed for each quarter. Timely filing and payment are necessary to avoid penalties or interest charges.

Filing Requirements and Due Dates

Employers in North Dakota need to follow clear payroll tax filing requirements to meet state regulations. Each form and submission has a specific purpose and timeline, with no room for delays or errors. Staying organized and adhering to these requirements ensures compliance and avoids penalties.

Forms and Frequency

North Dakota requires employers to report income tax withholding using Form 306. The filing frequency depends on the total withholding amount from the previous calendar year:

• Employers withholding $1,000 or more annually must submit Form 306 quarterly.

• Employers withholding less than $1,000 annually may file once per year.

Employers must register through the ND TAP system to file Form 306 electronically. Even if no wages are paid during a specific period, Form 306 must still be submitted to maintain an active withholding account.

Electronic Filing

North Dakota mandates electronic filing for most payroll tax forms and payments. Employers using payroll service providers or meeting the $1,000 annual withholding threshold must file electronically through ND TAP. Payments made using ACH Credit also meet this requirement. Paper submissions are not accepted for income tax withholding, ensuring all filings are processed online.

Other Required Submissions

In addition to Form 306, North Dakota requires several other payroll tax documents each year. Employers must submit:

• W-2 forms to report employee wages.

• 1099 forms for non-employee compensation.

• Form 307, which summarizes all W-2 and 1099 filings for the tax year.

These documents are due by January 31 annually and must be submitted electronically through ND TAP or compatible accounting software.

Penalties for Late Filing

Filing late or missing deadlines results in immediate financial consequences. North Dakota applies daily interest charges to unpaid tax balances until payments are completed. Additional penalties are assessed for failing to submit required forms on time. Employers can avoid these issues by closely monitoring due dates and maintaining accurate payroll records.

Reciprocity Agreements

North Dakota has established reciprocity agreements with Minnesota and Montana to simplify state income tax withholding for certain employees. These agreements allow eligible employees who live in one of these neighboring states but work in North Dakota to avoid having North Dakota state income tax withheld from their wages. Instead, only their home state's income tax applies, streamlining their tax obligations.

Employee Exemption Forms

Employees who qualify under the reciprocity agreements must complete Form NDW-R, the Reciprocity Exemption from Withholding form. This document is required to confirm their eligibility to opt out of North Dakota state income tax withholding. The form must include accurate personal information, such as residency details and employment status. Employees are responsible for signing and submitting the completed form to their employer. Without Form NDW-R, employers are required to withhold North Dakota state income tax by default.

Employer Action

Employers must retain a validated copy of Form NDW-R for every employee claiming reciprocity exemption. This form serves as proof of compliance and may be requested during audits or reviews by the IRS. Employers should verify that the form is fully completed, signed, and dated before processing payroll adjustments.

Additionally, North Dakota employers may need to send copies of Form NDW-R to the North Dakota Office of State Tax Commissioner. These submissions are due by March 31 each year. Employers who miss this deadline or fail to submit the forms risk penalties or compliance issues.

Keeping accurate records and staying on top of filing deadlines ensures smooth tax administration under reciprocity agreements. This reduces errors, avoids unnecessary withholding, and aligns with state requirements.

Electronic Payments and Withholding Adjustments

North Dakota simplifies payroll tax management for employers through electronic systems designed for accuracy and efficiency. The state's online tools streamline filing, payments, and updates, helping employers stay compliant without unnecessary hassle.

ND TAP

The North Dakota Taxpayer Access Point (ND TAP) is the state's online platform for managing payroll tax obligations. Employers use it to file returns, submit payments, and access tax records. Registration is straightforward, and once set up, employers can log in to manage their accounts securely.

ND TAP supports electronic submissions, including quarterly Form 306 filings and annual documents like W-2s. Employers can also track payment histories and confirm that filings have been processed. The platform ensures all submissions and payments meet state deadlines, reducing the likelihood of penalties.

ACH Debit/Credit

North Dakota offers ACH debit and credit options for payroll tax payments. ACH debit allows employers to authorize the state to withdraw payments directly from a designated bank account. This method is well-suited for recurring payments or employers who prefer a set-it-and-forget-it approach.

ACH credit, in contrast, requires employers to initiate the payment through their own bank. This method provides more control over the timing and execution of payments. Both options promote timely and accurate processing, ensuring consistent compliance with state requirements. Employers should double-check banking details and confirm available funds before initiating any transactions.

Changing or Updating Withholding

When employees update their federal Form W-4, employers must adjust North Dakota income tax withholdings to reflect these changes. Filing status, dependents, and additional withholding amounts directly affect state calculations. Employers should apply updates promptly to avoid payroll errors and ensure accurate tax payments.

Address changes also require immediate updates. Employers need to confirm the employee's residency and adjust payroll records to reflect the correct withholding requirements. Keeping records accurate ensures employees are taxed appropriately and prevents compliance issues during audits or reviews.

Corrections or Amended Returns

Payroll errors can disrupt tax compliance, but correcting them promptly keeps your records clean and avoids unnecessary penalties. North Dakota requires employers to amend payroll tax filings, including W-2s, 1099s, or Form 306, through specific processes. Each correction must follow state guidelines for accuracy and electronic submission.

Correcting W-2 or 1099 Forms

Mistakes on W-2 or 1099 forms require immediate attention. Employers must issue corrections using Form W-2C for W-2 errors and file it alongside Form W-3C (Transmittal of Corrected Wage and Tax Statements). This ensures the corrected information aligns with state and federal requirements. For 1099 errors, a corrected 1099 form must be completed, including the appropriate IRS error code to clarify the type of adjustment being made.

Each corrected form must include all accurate details from the original document, along with the updated information. North Dakota mandates electronic submission of corrected W-2s and 1099s through ND TAP or compatible accounting software.

Electronic Submission

North Dakota enforces electronic filing for all amended payroll tax documents. Employers must use ND TAP to submit W-2Cs, corrected 1099s, or updated Form 306 filings. The platform allows employers to review amendments before submission, ensuring all data is accurate. After submitting, ND TAP generates a confirmation, which should be saved as proof of compliance.

Submitting electronically also speeds up processing times, reducing the risk of delays or additional errors. Employers should log in to ND TAP promptly after identifying a mistake to begin the correction process.

Amending Form 306

Errors in income tax withholding require filing an updated Form 306. Employers should prepare the amended form with precise adjustments for the impacted reporting period. The updated Form 306 must also be submitted electronically through ND TAP.

When filing an amended Form 306, include a clear explanation of the error and the corrected figures. For example, if withholding amounts were calculated incorrectly, specify the original reported amount and the corrected total. Retain all related documentation, including ND TAP submission confirmations and any records used to calculate the correction, for future reference.

Thorough and timely corrections keep payroll records in compliance and demonstrate accurate handling of tax obligations.

Best Practices for Payroll Compliance

Payroll compliance in North Dakota requires attention to detail and consistent processes. Employers must focus on organized recordkeeping, staying informed about state updates, and meeting deadlines without fail. Each of these areas impacts your ability to manage payroll accurately and avoid penalties.

Retaining Payroll Records

Maintain payroll records for at least four years to ensure compliance and readiness for audits. Include key documents such as employee W-4 forms, pay stubs, Form 306 filings, and annual W-2 and 1099 submissions. Keep a detailed record of wages, taxes withheld, and adjustments made during each pay period.

Organize records in a secure system, whether digital or physical, and ensure quick access when needed. Audits, employee disputes, or tax corrections often require specific documentation, and incomplete records can cause unnecessary complications. A well-maintained archive of payroll data supports transparency and protects your business in case of inquiries.

Monitoring Updates and Rates

North Dakota revises payroll tax policies regularly, including withholding tables, SUI wage bases, and tax rates. Employers who fail to adjust to these changes risk payroll errors. For example, the 2025 SUI taxable wage base is $45,100, which differs from previous years. Employers must confirm their assigned SUI rate annually, especially those with experience-rated rates tied to unemployment claims history.

Periodic reviews of withholding tables are equally important. Withholding calculations must align with updated income brackets and filing statuses provided by employees. Missing an update can result in incorrect withholdings, which may lead to penalties or underpayments. Employers benefit from setting reminders to verify updates through ND TAP or state communications.

Maintaining Timely Remittances

Late tax payments disrupt compliance and result in financial penalties. Employers must submit income tax withholding through Form 306 on a quarterly or annual basis, depending on the total amount withheld. SUI payments follow the same schedule, with deadlines tied to the end of each quarter.

Consistent on-time remittances are easier with scheduled electronic payments. ND TAP supports ACH debit and credit, which allow employers to process payments efficiently and confirm receipt. Regularly monitoring due dates and automating submissions prevents delays and keeps your payroll operations aligned with state requirements.

FAQs

Payroll taxes in North Dakota come with specific rules and processes that employers need to follow carefully. Below are straightforward answers to common questions about managing state payroll taxes for your workforce.

What is the payroll tax in North Dakota?

North Dakota payroll taxes include two primary obligations: income tax withholding and state unemployment insurance (SUI). Income tax withholding applies to employee wages that are subject to federal income tax withholding. SUI is required for most employers and is calculated on the first $45,100 of employee wages for 2025. Rates for SUI vary depending on whether the employer is new or experienced, as well as the claims history.

Do you pay state income tax in ND?

State income tax applies to employees working in North Dakota or to North Dakota residents employed in other states, unless the other state requires income tax withholding. Employers are responsible for withholding these taxes from employee wages and remitting them to the state. Rates range from 1.95% to 2.5%, depending on the employee's taxable income.

Does ND have a state tax withholding form?

North Dakota does not require a separate state-specific withholding form. Instead, employers use the federal Form W-4 to calculate state income tax withholding amounts. However, employees residing in Minnesota or Montana who qualify for reciprocity must complete Form NDW-R to claim exemption from North Dakota withholding. Employers must retain these forms and submit them to the state as required.

What is the state payroll tax?

State payroll tax in North Dakota refers to both income tax withholding and SUI contributions. Employers calculate income tax withholding based on federal Form W-4 data and apply state-specific rates. SUI is calculated on taxable wages up to the annual wage base, which is $45,100 for 2025.
