Indiana DOR 2026: State Tax Filing, Refund, Login & Phone
A practical Indiana Department of Revenue guide for taxpayers, businesses, employers, tax professionals, remote sellers and motor carriers who need INTIME login help, refund status, income tax filing, sales tax registration, withholding, corporate tax, county income tax, notices, tax warrants, district offices and official Indiana DOR contact paths.
Quick Answer: What Does the Indiana Department of Revenue Do?
The Indiana Department of Revenue administers Indiana state tax programs, including individual adjusted gross income tax, county income tax administration, sales and use tax, withholding, corporate adjusted gross income tax, business tax accounts, tax warrants, payments, refunds, letters, audits, district offices and INTIME online services. Most modern Indiana tax account actions begin with INTIME, the Indiana Taxpayer Information Management Engine.
For individuals
Use DOR for Indiana Form IT-40, refund status, INTIME, payments, county tax, billing, tax warrants, payment plans, letters, Taxpayer Advocate help and tax account questions.
For businesses
Use DOR and INTIME for sales tax, withholding, corporate tax, account updates, business closure, Registered Retail Merchant Certificates, nonprofit questions and food and beverage tax.
For motor carriers
Indiana DOR also has Motor Carrier Services for IRP, IFTA, OSOW and related carrier accounts, but ordinary driver license and registration questions are usually BMV/county matters.

Indiana Local Tips: INTIME, INBiz, County Tax, BMV and Property Tax Confusion
Indiana tax searches are confusing because users may need DOR, INTIME, INBiz, the Secretary of State, BMV, Department of Workforce Development, county treasurer, county assessor or a district office. Use these local tips before you go to the wrong portal.
Indianapolis / Marion County tip
Many Indianapolis users mix up DOR income tax, Marion County property tax and city/county business requirements. DOR handles state tax accounts; property tax bills usually start with county offices.
Northwest Indiana county tax tip
Lake, Porter and nearby county taxpayers should pay close attention to county income tax rates and residence/work county questions. Indiana state tax and county tax are not the same item.
Retail merchant certificate tip
If your business sells taxable goods or tangible personal property, DOR says you need to register to collect Indiana’s 7% sales tax and receive a Registered Retail Merchant Certificate.
Restaurants and local food & beverage tax
Some counties or municipalities have food and beverage taxes in addition to sales tax. DOR provides rates, but local business licensing may still require city or county action.
BMV vs DOR confusion
Indiana BMV handles many driver license, plate, title and registration tasks. Indiana DOR has Motor Carrier Services and tax programs, but normal driver license help is usually not a DOR issue.
District office strategy
DOR district offices can help with many tax questions, but check hours, appointment availability and the service type first. Bring the exact Letter ID, tax period and payment proof.
Indiana DOR Action Map: What You Need vs Where to Go

Indiana INTIME Login: File, Pay, Refund Status and Account Access

Indiana Individual Income Tax 2026: IT-40, 2.95% Rate, County Tax and Filing Help
Indiana individual adjusted gross income tax is imposed on federal adjusted gross income with Indiana adjustments. For 2026, DOR lists the Indiana individual adjusted gross income tax rate as 2.95%. County income tax may also apply, so Indiana taxpayers should not calculate state tax and stop there.
| Individual tax item | What to know | Best action |
|---|---|---|
| Indiana return | Indiana residents, part-year residents and nonresidents with Indiana income should review filing rules. | Use current IT-40 or related forms and instructions. |
| 2026 state rate | The 2026 Indiana individual adjusted gross income tax rate is 2.95%. | Verify current filing year instructions before submitting. |
| 2027 rate note | DOR’s rate page states the rate adjusts to 2.90% in 2027. | Do not use 2027 rates for 2026 returns. |
| County income tax | County income tax rates may change in January and October. | Use the correct year county tax chart and residence/work county rules. |
| INTIME payments | Income tax bills can be paid through INTIME. | Keep confirmation numbers and payment proof. |
| Unemployment 1099-G issue | Unemployment benefits and fraud questions may involve the Indiana Department of Workforce Development, not only DOR. | Contact DWD if you received a suspicious unemployment 1099-G. |
Indiana DOR Refund Status: INTIME, Option 3, E-Filed vs Paper Return Timelines
Indiana DOR says taxpayers can check refund status on INTIME or call 317-232-2240 and choose option 3. E-filed returns may take up to three weeks to process, while paper-filed returns may take up to 12 weeks. Your bank may take additional time to deposit a refund.
Before checking refund status
- Wait a reasonable processing period after filing.
- Know whether you e-filed or paper-filed.
- Prepare SSN, tax year and expected refund amount.
- Check whether DOR sent a letter or identity request.
- Confirm bank deposit timing if direct deposit was requested.
When a refund is delayed
Common delay reasons include paper filing, identity verification, missing documents, math errors, debt offsets, incorrect bank details, amended returns or a DOR letter that has not been answered. Use INTIME messages when you need secure help.
Indiana Business Tax Registration: INBiz, INTIME, RRMC and Business Account Setup
Indiana businesses may need to register for multiple tax types depending on activity. DOR’s small business education resources say registration is required for all tax types applicable to your business, including Indiana retail sales, withholding, out-of-state sales, gasoline use taxes, metered pump sales, tire fees, fuel taxes, prepaid wireless charges, food and beverage taxes, county innkeeper’s taxes, heavy vehicle rental tax and motor vehicle rental taxes.
Businesses should check registration when they
- Sell taxable goods or tangible personal property in Indiana.
- Need a Registered Retail Merchant Certificate.
- Hire employees and need withholding tax.
- Sell into Indiana as an out-of-state or remote seller.
- Operate a restaurant, lodging business or taxable rental activity.
- Need motor carrier, fuel, tire, food and beverage or special tax accounts.
Prepare before registration
- FEIN or owner identification.
- Legal name, trade name and entity details.
- Indiana Secretary of State or INBiz record if applicable.
- Business location and mailing address.
- First date of Indiana taxable activity.
- Tax type, business activity and filing frequency details.
Indiana Business Workflow: INBiz → IRS → DOR → Local License
Indiana business owners often register in one place and miss another. Use this workflow before collecting tax, hiring employees or opening a location.
| Step | Where to go | Why it matters | Common mistake |
|---|---|---|---|
| 1. Business entity / INBiz | INBiz and Secretary of State | Forms or searches entities, registrations and business records. | Thinking DOR forms every business entity. |
| 2. Federal EIN | IRS | Needed for payroll, banking and many tax registrations. | Paying unnecessary third-party EIN fees. |
| 3. Indiana tax accounts | Indiana DOR / INTIME | Registers and manages sales tax, withholding and other DOR tax accounts. | Selling taxable items before getting RRMC. |
| 4. Local food, beverage, innkeeper or business rules | County/city and DOR rate pages | Some local taxes and licenses can apply beyond normal sales tax. | Assuming sales tax registration covers every local obligation. |
| 5. Industry permits | Relevant state/local agencies | Alcohol, tobacco, motor carrier, fuel, restaurants and regulated industries may need additional approvals. | Only registering with DOR and ignoring licensing. |
Indiana Sales and Use Tax: 7% Rate, RRMC, Remote Sellers and Use Tax
Indiana’s statewide sales tax rate is 7%. DOR’s sales tax page says businesses selling goods or tangible personal property need to register to collect seven percent sales tax. After registration is completed and processed, the business receives a Registered Retail Merchant Certificate.
| Sales tax topic | What to know | User action |
|---|---|---|
| Statewide rate | Indiana sales tax is 7% statewide. | Do not add county sales tax unless a separate special tax applies. |
| RRMC | Registered Retail Merchant Certificate is issued after sales tax registration is processed. | Display one certificate for each retail business location if required. |
| Use tax | Indiana use tax is also 7%, complementary to sales tax. | Report use tax when taxable purchases were not taxed correctly. |
| Remote sellers | Remote sellers may need to register, collect and file Indiana sales tax depending on rules and activity. | Use DOR remote seller and Streamlined Sales Tax resources. |
| Food and beverage tax | Some counties or municipalities have food and beverage tax rates. | Check DOR rate tables and county auditor/local rules. |
| Out-of-state sales tax paid | If another state collected less than 7%, Indiana use tax may be the difference. | Keep receipts and report correctly. |
Indiana Withholding Tax: Employers, INTIME, WH-1, WH-3, W-2 and 1099 Help
Indiana withholding tax applies when employers withhold Indiana state and county income taxes from employee wages. DOR’s withholding page explains that INTIME enables customers to manage tax obligations in one convenient location, 24/7, and withholding obligations can be submitted and paid through INTIME.
Employer withholding checklist
- Register for withholding tax when hiring employees.
- Use the correct Indiana state and county rates.
- File and pay withholding obligations through INTIME where applicable.
- Keep WH-1, WH-3, W-2 and 1099 records.
- Update business profile if employees are added later.
- Use current Departmental Notice #1 for withholding county tax rates.
County withholding detail
County income tax rates may change in January and October. Employers should use DOR’s most recent county tax information and withholding notices rather than relying on old payroll settings.
Indiana Corporate Adjusted Gross Income Tax: 4.9%, Estimated Payments and Business Filing
Indiana corporate adjusted gross income tax generally applies to C corporations doing business in Indiana. Indiana corporate estimated payment guidance states the adjusted gross income tax rate is 4.9% of Indiana adjusted gross income after apportionment and modifications.
Businesses that should review corporate tax
- C corporations doing business in Indiana.
- Corporations with Indiana-source income.
- Businesses with Indiana property, payroll or sales.
- Entities receiving DOR corporate notices.
- Tax professionals handling Indiana apportionment and estimated payments.
Do not confuse entity filing with tax filing
Secretary of State/INBiz entity filings and Indiana DOR tax filings are separate. A business may need entity filings, DOR tax accounts, sales tax, withholding tax and corporate income tax depending on activity.
Indiana County Income Tax: Residence, Work County, Local Rates and Payroll Mistakes
Indiana local income tax is a major source of confusion. DOR explains county tax for residents is generally based on county of residence as of January 1, while for many nonresidents it may be based on the individual’s principal place of business or employment as of January 1.
| County tax issue | What to know | Best action |
|---|---|---|
| Resident county | Resident county rules usually look at the county of residence on January 1. | Use the correct county for the tax year. |
| Nonresident county | For many nonresidents, county tax can be tied to principal place of work/business. | Check instructions and payroll data. |
| Rate changes | County income tax rates may be updated in January and October. | Use current DOR county rate charts. |
| Payroll withholding | County tax errors can create underpayment or overpayment issues. | Update payroll when county rate notices change. |
| Moving counties | Moving during the year can create county questions. | Follow current IT-40 instructions for the specific filing year. |
Indiana DOR Motor Carrier Services: IRP, IFTA, OSOW and One Stop Truck Shop
Indiana DOR’s Motor Carrier Services handles specialized carrier-related services such as IRP, IFTA, oversize/overweight and certain carrier accounts. These are not the same as ordinary passenger vehicle registration or driver license questions.
Motor carrier services may include
- IRP accounts and fleet registration.
- IFTA fuel tax reporting.
- OSOW permits.
- Motor Carrier Services appointments.
- Fuel tax and special tax support.
- One Stop Truck Shop support.
Prepare before contacting MCS
Have carrier name, USDOT/FEIN, account numbers, vehicle details, plates, tax periods, prior filings and notice information ready. DOR lists Motor Carrier Services as a separate contact path from normal tax customer service.
Indiana DOR vs BMV vs Property Tax: Where Users Often Go Wrong
Indiana DOR is not the right office for every Indiana “tax” or “vehicle” search. Driver license, title, vehicle registration and plates are usually BMV issues. Property tax bills are usually local county issues.
| Issue | Usually correct office | Why |
|---|---|---|
| Driver license | Indiana BMV | Driver licensing is handled by BMV, not normal DOR tax customer service. |
| Vehicle title/plate/registration | Indiana BMV | Most ordinary vehicle registration tasks are BMV services. |
| Property tax bill/payment | County treasurer | County treasurers generally collect local property tax bills. |
| Property value/assessment | County assessor | Assessments and valuation notices are local property tax matters. |
| Unemployment 1099-G fraud | Indiana Department of Workforce Development | DWD handles unemployment benefits and fraud reporting. |
| State income/sales/withholding tax | Indiana DOR / INTIME | DOR administers state tax accounts and returns. |
Indiana DOR Notice, Bill, Letter ID, Collection or Tax Warrant: What To Do Next
A DOR letter can involve a missing return, refund review, payment mismatch, business account issue, withholding problem, sales tax filing, collection, tax warrant or account verification. INTIME allows users to respond to letters, notices and bills using a Letter ID found at the top of DOR letters.
| Notice type | First thing to check | Best action |
|---|---|---|
| Letter ID notice | Letter ID, tax type, tax year and due date. | Use INTIME to respond where available. |
| Refund delay | Refund status, filing method and DOR letter request. | Check INTIME and answer requested information. |
| Tax bill | Tax type, tax period, amount and payment deadline. | Use INTIME payment or contact DOR if records disagree. |
| Sales tax notice | RRMC, filing period, taxable sales and payment confirmation. | Compare INTIME returns and sales records. |
| Withholding notice | Payroll period, WH-1/WH-3, W-2/1099 data and county rate. | Gather payroll and payment records before calling. |
| Tax warrant | Account balance, warrant basis and legal deadlines. | Contact DOR quickly and review expungement guidance if applicable. |
Indiana Tax Amnesty, Taxpayer Advocate and When Regular Support Is Not Enough
Indiana DOR may run special programs, announcements and taxpayer relief processes such as Tax Amnesty 2026 or Taxpayer Advocate assistance. These programs can have strict dates, eligibility rules and account-specific requirements, so always use official DOR pages before acting.
Taxpayer Advocate Office may help when
- You have tried normal DOR channels without resolution.
- You believe a process violates taxpayer rights.
- You need help understanding a tax warrant issue.
- You have a hardship or repeated account issue.
- You need assistance navigating complex correspondence.
Use official program pages
Do not rely on old blog posts for amnesty or relief dates. Tax amnesty, settlement, warrant and advocate programs can change by law, year and account type.
