Indiana Nonresident Withholding Guide – If your business operates in Indiana, hires nonresident employees, or has nonresident partners or shareholders in a pass-through entity, you must understand Indiana’s nonresident withholding rules. This comprehensive guide explains Indiana nonresident withholding requirements, current tax rates, required forms, filing deadlines, and key exceptions based on official Indiana Department of Revenue (DOR) resources. Proper compliance helps avoid penalties and ensures smooth tax reporting for nonresidents earning Indiana-source income.
What Is Indiana Nonresident Withholding?
Indiana nonresident withholding requires payers (employers, partnerships, S corporations, and other entities) to withhold Indiana state and county income taxes from payments made to nonresidents for Indiana-source income. This includes wages for services performed in Indiana and distributive shares of income from pass-through entities doing business in the state.
Nonresidents are individuals who are legal residents of another state but earn income from Indiana sources (e.g., working temporarily in Indiana, owning property, or receiving pass-through income). Withholding ensures the state collects tax upfront on this income. Indiana does not tax nonresidents on income earned outside the state.
Who Must Comply with Indiana Nonresident Withholding Requirements?
Employers must withhold from nonresident employees’ wages for work performed in Indiana, unless an exception applies (such as reciprocity or the 30-day safe harbor).
Partnerships, S corporations, and certain trusts/estates must withhold on distributions or credits to nonresident partners, shareholders, or beneficiaries from Indiana-source income. These entities generally file a composite return and remit withholding via Form IT-6WTH (or use Form DB020W-NR for certain one-time payments).
Any business with employees, nonresident shareholders, nonresident partners, or beneficiaries receiving distributions must register as a withholding agent. Even if no tax is due in a period, periodic filings are still required.
Reciprocity Agreements: When Withholding Is Not Required for State Tax
Indiana has reciprocity agreements with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin. Residents of these states working in Indiana generally do not have Indiana state adjusted gross income tax (AGIT) withheld on wages, salaries, tips, or commissions. However:
- Indiana local income tax (LIT/county tax) is still required if the employee’s principal place of employment is in an Indiana county as of January 1.
- Income from other sources (e.g., non-wage income) remains subject to Indiana tax.
- Employees must provide Form WH-47 (Certificate of Residence) to claim reciprocity.
Reciprocity does not apply to residents of other states.
30-Day Safe Harbor Rule for Nonresident Employees (Effective 2024 Onward)
Starting in 2024 (and continuing in 2026), employers are not required to withhold state or county income tax from qualified nonresident employees who work in Indiana for 30 days or less during the calendar year, provided one of these conditions is met:
- The employer maintains a time-and-attendance system that tracks work locations contemporaneously, and the employee is reasonably expected to work 30 days or fewer in Indiana.
- The employee submits a properly completed Form WH-4AFF (Withholding Tax Waiver for Nonresident Employee).
Important notes:
- Days worked for any previous Indiana employer count toward the 30-day total.
- If the employee ultimately works more than 30 days, the employer must withhold for all days (including the first 30) or make up the shortfall reasonably.
- This rule does not apply to certain professionals (e.g., professional athletes, entertainers, or public figures).
- Employees can request a refund on their Indiana return if tax was withheld unnecessarily.
Current 2026 Indiana State and County Tax Rates for Nonresident Withholding
- State Adjusted Gross Income Tax (AGIT) rate: 2.95% (reduced from 3.00% effective January 1, 2026; further reduction to 2.90% scheduled for 2027).
- County (Local Income Tax – LIT) rates: Vary by county (0% to over 3% in some cases). Rates are determined by the employee’s county of residence (or principal place of work/business in Indiana) as of January 1 each year. Six counties have rate changes effective January 1, 2026.
Use the latest Departmental Notice #1 (available on the DOR website) for the full county rate chart and deduction constant tables to calculate withholding accurately.
Exemptions and dependents reduce taxable wages before applying these rates.
Key Forms for Indiana Nonresident Withholding
Use these official DOR forms (downloadable from in.gov/dor):
- WH-4: Employee’s Withholding Exemption & County Status Certificate (completed by all employees).
- WH-47: Certificate of Residence (for reciprocity claims).
- WH-4AFF: Withholding Tax Waiver for Nonresident Employee (for 30-day safe harbor).
- WH-3: Annual Withholding Reconciliation (due January 31; reconciles all withholding).
- WH-1: Monthly/quarterly/annual withholding return.
- IT-6WTH: Used by pass-through entities to remit nonresident withholding with IT-20S or IT-65 returns.
- DB020W-NR: For one-time or annual distributions to nonresidents when no separate withholding account exists.
- IN K-1: Issued to nonresident partners/shareholders showing withholding.
Additional forms like WH-4MIL (military spouses) may apply in specific cases.
How to Register as a Withholding Agent
Businesses must register via INBIZ (inbiz.in.gov) using a federal EIN. Registration is required if you have employees or make payments to nonresident partners/shareholders/beneficiaries. Once registered, you receive account information for filing WH-1, WH-3, and related forms.
Filing and Remitting Nonresident Withholding Taxes
- Payroll withholding: File WH-1 periodically (monthly, quarterly, or annually depending on amount due) and reconcile annually with WH-3 by January 31.
- Pass-through entities: Remit nonresident withholding with the entity’s annual return (IT-20S or IT-65) using IT-6WTH (due 15th day of the 4th month after year-end). Composite returns cover most nonresidents.
- Electronic filing is mandatory for businesses issuing 25+ W-2/W-2G/1099-R statements.
- Use INTIME (intime.dor.in.gov) for convenient electronic payments and filings.
Penalties for Non-Compliance
Late WH-1 filings incur penalties up to 20% (minimum $5). Late WH-3 filings cost $10 per withholding document. Failure to withhold or remit can lead to additional interest, penalties, and potential personal liability. Always file returns even if no tax is due.
Indiana Nonresident Individual Filing Requirements
Nonresidents with Indiana-source income (beyond the 30-day exception or reciprocity wages) generally file Form IT-40PNR (Part-Year Resident or Nonresident Individual Income Tax Return). Residents of reciprocity states with only wage income may use IT-40RNR. Withholding credits from W-2s or IN K-1s reduce tax owed.
