Indiana INTIME: Register Your Business Tax Account With the Department of Revenue

Indiana INTIME: Register Your Business Tax Account With the Department of Revenue

Once your Indiana business is formed, the next state tax step is getting a business tax account with the Indiana Department of Revenue (DOR). Owners often use "INTIME" and "registration" as if they were the same thing. They are not. Registration puts your business on the state's tax rolls. INTIME is DOR's e-services portal for managing those taxes after you are registered, including filing, paying, and withholding. This guide covers both steps, the withholding setup that new employers most often get wrong, and the separate unemployment insurance registration with the Department of Workforce Development (DWD).

Informational content only. This article is not legal or tax advice. Tax rules and agency procedures change, and your facts determine what applies. Confirm current requirements with the agency named in each section, and talk to a qualified CPA or attorney before you make tax or payroll decisions.

Registration and the INTIME portal are different steps

Registration and the portal get confused because they connect to each other, but they do different jobs.

  • Registration is how your business gets an Indiana business tax account with DOR. A business registers with the Department of Revenue through INBiz, the state's online business portal.
  • INTIME (Indiana Taxpayer Information Management Engine, at https://intime.dor.in.gov) is where you manage the account day to day: filing returns, making payments, and handling withholding.

You register first. You log in to INTIME after you have the identifiers DOR issues to your business.

What to have ready before you start

DOR publishes a BT-1 checklist that lists the information needed to complete registration. Print it and gather everything before you open INBiz. A session that stalls halfway through because you do not have a number on hand wastes time and can leave you starting over. Typical items include the legal name and entity type exactly as filed with the Indiana Secretary of State, the business address for each location, and your federal employer identification number (FEIN) if you have one. Check the BT-1 checklist for the complete list, since it controls.

Step 1: Register with DOR through INBiz

Start at DOR's Register a Business page at https://www.in.gov/dor/i-am-a/business-corp/business-education/register-business/, which takes you into INBiz. Keep three rules in mind as you work through the form.

  • Each location registers separately. If you operate out of more than one place, each location needs its own registration. Form BT-1C lets you consolidate sales tax filing across locations, so ask DOR whether it fits how your business is organized before you assume you need one filing per site.
  • Taxable sales require a sales tax permit. If you sell taxable goods, you need a Registered Retail Merchant Certificate. The INBiz fee calculator shows the fee as $25. Indiana's state sales tax rate is 7%, and the permit application is on the DOR page linked above.
  • Indiana has no single business license. The state's Business Owner's Guide says there is no comprehensive state business license. Depending on your field, you may still need a profession-specific license from the Indiana Professional Licensing Agency, plus local permits or zoning approval from your city or county. Registering with DOR does not replace those approvals.

Step 2: Collect your TID and Letter ID

To log in to INTIME for your business, you need two identifiers:

  • Your business's Indiana taxpayer identification number (TID).
  • A Letter ID, printed in the top right corner of a DOR letter.

Keep every DOR letter about the account, and save the Letter ID with your business records, not only in an email inbox. If you cannot find a DOR letter for the business, do not guess at the number. Contact DOR through the agency site at https://www.in.gov/dor/ and confirm which identifier applies before you try to log in.

Step 3: Create your INTIME logon

Go to https://intime.dor.in.gov and create a logon using the TID and the Letter ID. Once you are in, you can manage filing and payments for the account. Withholding is part of the same portal, so this is where you will set it up. Do the setup before your first payroll run, not after you have already paid someone. Retroactive fixes take more work than a clean first filing.

Withholding tax: who you withhold for and where the county comes from

If you have employees, you must withhold Indiana tax from their pay. Withholding covers two pieces: state tax plus county tax. The county piece depends on where the employee lives or works, not where your office is located.

  • Resident employees: the county is the employee's county of residence on January 1.
  • Employees who live out of state: the county is their county of principal employment.

DOR's Departmental Notice #1 explains how these county rules apply. Read it before you set up payroll, and give it to whoever runs your payroll software or service so the county codes are right from the first paycheck.

The 30-day nonresident exception

An employer does not need to withhold for a nonresident who works in Indiana 30 days or less in the year, when the employee files Form WH-4AFF with you. Keep the signed form in the employee's file before you rely on the exception. If an employee's Indiana workdays go past 30, the exception no longer covers that employee, so confirm with DOR how withholding should be handled for them.

The WH-1 withholding return

The WH-1 is the withholding return form. This guide does not state how often you must file it, because the filing frequency rules were not verified here. Confirm the WH-1 filing schedule with DOR before your first payroll, then set your payment calendar to match what DOR tells you. Do not copy a schedule from another state or from a payroll vendor's default settings without checking it against DOR.

Unemployment insurance is a separate registration with DWD

Income tax withholding and unemployment insurance are different programs. Employers register with the Indiana Department of Workforce Development through Employer Self Service at https://uplink.in.gov/ESS. You register in the first quarter you qualify as an employer, and you need your FEIN and your subject wages to complete the registration.

The INBiz roadmap includes a DWD registration step, so it is easy to assume DOR handles unemployment insurance as well. It does not. Confirm the qualifying rules and deadlines directly with DWD. Paper State Form 2837 is available, but paper slows registration down. Use Employer Self Service unless you have a specific reason not to.

New hire reporting is its own system

New hire reporting is a separate requirement from INTIME, the WH-1, and Employer Self Service. Registering with DOR or DWD does not cover it. Set it up as its own task, confirm the requirements and deadlines with the agency that administers it, and assign one person to own it so it does not slip during the first weeks of hiring.

Common mistakes first-time employers make

  • Treating INBiz and INTIME as one step. Register first, then log in.
  • Registering one location when the business operates several, or not realizing each location registers separately.
  • Assigning county withholding based on the company's office address instead of the employee's county of residence or principal employment.
  • Skipping the signed WH-4AFF for a nonresident employee who may qualify for the 30-day exception.
  • Waiting until the first paycheck to set up withholding in INTIME.
  • Assuming DOR registration also covers unemployment insurance with DWD.

Setup checklist

  1. Confirm your business entity is formed with the Indiana Secretary of State, Business Services Division (https://www.in.gov/sos/business/).
  2. Gather the BT-1 checklist information and your FEIN.
  3. Register with DOR through INBiz, with one registration for each location.
  4. If you sell taxable goods, pay the $25 Registered Retail Merchant Certificate fee and complete the sales tax permit.
  5. Save your TID and Letter ID with your business records.
  6. Create your INTIME logon and set up withholding before your first payroll.
  7. Collect a signed WH-4AFF from any nonresident employee you plan to treat under the 30-day exception.
  8. Confirm your WH-1 filing schedule with DOR.
  9. Register with DWD through Employer Self Service in the first quarter you qualify.
  10. Set up new hire reporting as a separate task.

When to bring in a professional

A sole owner with one location and no employees can often complete DOR registration alone. Multiple locations, employees who live or work across state lines, or any question about how withholding applies to a specific worker are the situations where a CPA or payroll provider is worth the cost. The Indiana Small Business Development Center (https://isbdc.org/) provides business advising, and the U.S. Small Business Administration's Indiana district page (https://www.sba.gov/district/indiana) can point you to local resources.
