What Is Indiana Payroll Tax?
Indiana payroll tax refers to the state and county payroll taxes that employers must withhold from employee wages or pay directly to state agencies. These taxes fund unemployment benefits and the state's and counties' income tax systems.
Indiana's state-level system is straightforward a flat income tax rate and one unemployment tax but every one of Indiana's 92 counties levies its own local income tax on top of the state rate, making Indiana's local tax layer genuinely relevant to virtually every employer in the state, unlike Ohio or Pennsylvania local systems, which only apply in specific municipalities. Indiana payroll taxes are administered by two state agencies the Indiana Department of Workforce Development, or DWD (unemployment insurance), and the Indiana Department of Revenue, or DOR (state and county income tax withholding, filed together).
Most Indiana employers are responsible for the following payroll tax requirements:
- Unemployment Insurance (UI), administered by the DWD
- Indiana Personal Income Tax withholding, administered by the DOR, at a flat rate
- County Income Tax withholding, administered alongside state withholding by the DOR, at a rate set individually by each of Indiana's 92 counties
Because Indiana has no state disability insurance program, employers generally have fewer types of taxes to manage than in states like California or New York but because county tax applies everywhere in the state rather than in just a few cities, it's a genuine, universal part of Indiana payroll rather than an edge case.
Indiana Payroll Taxes at a Glance
| Payroll Tax | Paid By | Purpose |
|---|---|---|
| Unemployment Insurance (UI) | Employer | Provides temporary income for eligible unemployed workers |
| Personal Income Tax (state) | Employee (withheld by employer) | Flat-rate state income tax withheld from employee wages |
| County Income Tax | Employee (withheld by employer) | Local income tax, set individually by each of Indiana's 92 counties |
Understanding who pays each tax and that county tax is based on where an employee lives, not where the employer is located helps employers avoid the most common Indiana payroll mistake: applying the wrong county's rate.
Indiana Employer Payroll Tax Responsibilities
Every employer with workers in Indiana has payroll tax responsibilities beyond simply issuing paychecks. Depending on your business, you'll generally need to:
- Register your business with the DWD for unemployment insurance and with the DOR for state and county withholding tax.
- Determine each employee's Indiana county of residence as of January 1 of the applicable tax year.
- Withhold state income tax and the correct county income tax from every paycheck.
- Pay employer UI contributions.
- File quarterly UI wage reports and periodic combined state/county withholding returns.
- Update an employee's county tax rate promptly if they move to a different Indiana county during the year.
- Maintain payroll records for state compliance.
Many businesses automate these tasks using payroll software with built-in Indiana county tax tables, since manually tracking 92 different county rates is impractical without it.
Types of Indiana Payroll Taxes
Unemployment Insurance (UI)
Unemployment Insurance is an employer-funded payroll tax administered by the DWD that provides temporary financial assistance to eligible workers who lose their jobs through no fault of their own.
Employers pay this tax directly it is never deducted from employee paychecks.
New employers, and employers restarting Indiana employment after a break of a year or more, are assigned a fixed rate by industry. Employers that have been operating for three or more years are rated based on their usage of the unemployment system factors include the number of former employees drawing benefits, total payroll subject to UI contribution, any voluntary payments made, and whether all or part of an existing Indiana business was transferred to them.
Key Facts
- Paid entirely by employers Indiana has no employee UI contribution
- Calculated on the first $9,500 of each employee's wages per year a wage base that generally doesn't change from year to year
- Typical new employer rate is 2.5%
- Experience-rated employers in good standing range from a 0.50% minimum up to a 7.40% maximum; a higher 9.40% delinquent rate applies to employers who fail to pay on time
- Must be reported to the DWD every quarter
Indiana Personal Income Tax (PIT) Withholding
Indiana imposes a flat-rate personal income tax on wages, and the rate has been on a scheduled downward path for several years running it's set to decrease again to 2.90% in 2027.
Employers are responsible for:
- Withholding the flat state rate from every paycheck, based on the employee's WH-4 exemption elections
- Reporting withholding to the Indiana Department of Revenue
- Depositing withheld taxes according to a schedule based on total withholding liability
- Filing periodic withholding returns (state and county combined) and an annual reconciliation, including W-2 filing with the state
County Income Tax
Unlike Ohio's or Pennsylvania's local tax systems, which only apply in specific taxing municipalities, every single one of Indiana's 92 counties levies its own local income tax meaning nearly every Indiana employer needs to account for county tax for every employee, not just those working in certain cities.
Key rules employers need to know:
- County tax is based on the employee's county of residence, not the county where the employer or work location is based a distinction that trips up many employers new to Indiana
- Both an employee's county of residence and county of principal employment are determined as of January 1 of the calendar year in which their taxable year begins
- County rates vary widely some counties charge well under 1%, while others charge over 3% and the Indiana DOR publishes an updated county rate table (Departmental Notice #1) at least annually, sometimes with mid-year changes
- If an employee moves to a different Indiana county partway through the year, employers need to update that employee's withholding rate going forward
- County tax is reported and remitted together with state withholding, through the same combined filing, rather than through a separate local tax collector as in Ohio or Pennsylvania
Because county tax genuinely applies to virtually every Indiana employee, this isn't an edge case to check for it's a standard part of every Indiana payroll run.
Which Payroll Taxes Are Paid by Employers vs Employees?
| Tax | Employer Pays | Employee Pays |
|---|---|---|
| Unemployment Insurance (UI) | YES | NO |
| Personal Income Tax (state) | NO | Withheld from wages (flat rate) |
| County Income Tax | NO | Withheld from wages (varies by county of residence) |
Indiana places the entire unemployment tax burden on the employer, while both layers of income tax state and county are withheld from employee wages based on where each employee lives.
Indiana Payroll Tax Rates for Employers
Understanding current Indiana payroll tax rates is essential for calculating payroll accurately. The state income tax rate is on a scheduled multi-year decline, and county rates are reviewed and can change annually always verify the latest figures before processing payroll.
Indiana Payroll Tax Rates at a Glance
| Payroll Tax | Who Pays | General Rate | Taxable Wage Base |
|---|---|---|---|
| Unemployment Insurance (UI) | Employer | Typical new employer rate: 2.5%. Experienced employers in good standing: 0.50%–7.40% | First $9,500 of each employee's wages per year |
| Personal Income Tax (state) | Employee | Flat 2.95% for 2026, down from 3.05% previously, with a further scheduled drop to 2.90% in 2027 | Applies to taxable wages, no brackets |
| County Income Tax | Employee | Varies by county of residence; some counties adjusted their rates for 2026 | Applies to taxable wages, based on the employee's Indiana county of residence as of January 1 |
According to the Indiana Department of Revenue's official Departmental Notice #1 (effective January 1, 2026), the state adjusted gross income tax rate for individuals is 2.95% for 2026, continuing a multi-year phase-down. Several Indiana counties adjusted their local rates effective for 2026 as well the DOR notes any county whose rate has changed since the prior notice with an asterisk in its published table. Indiana has also conformed to certain federal provisions exempting qualified overtime and tip income from state and county income tax for 2026.
Instead of memorizing a specific rate, employers should focus on reviewing the DOR's current Departmental Notice #1 for county rates, tracking the current flat state rate, and filing returns on time.
Understanding Taxable Wages
Indiana UI tax applies to taxable wages up to the annual wage base. Taxable wages generally include:
- Hourly wages
- Salaries
- Bonuses
- Overtime pay (though qualified overtime is exempt from Indiana state and county income tax for 2026 under recent federal conformity)
- Commissions
- Tips (similarly exempt from state and county income tax for 2026)
- Certain taxable fringe benefits
Once an employee's wages for the year cross the $9,500 UI wage base, no further UI tax is owed on that employee's wages for the remainder of the year. State and county income tax withholding, by contrast, generally apply more broadly to taxable wages with no separate wage base cap, subject to the new overtime and tip exemptions noted above.
Indiana Payroll Tax Filing Deadlines
Meeting payroll tax deadlines is just as important as calculating taxes correctly. Late filings or payments can lead to penalties and interest charges.
Unemployment Insurance (Quarterly Wage Report)
| Reporting Quarter | Filing Deadline |
|---|---|
| January – March | April 30 |
| April – June | July 31 |
| July – September | October 31 |
| October – December | January 31 |
State and County Income Tax Withholding
Indiana state and county withholding are filed together on a single return, with deposit frequency (monthly, quarterly, or annually) determined by the amount withheld. An annual reconciliation, including state and county W-2 reporting, is also required.
If a deadline falls on a weekend or state holiday, the due date generally moves to the next business day.
How to Register for Indiana Payroll Taxes
Before paying employees, businesses typically need to register with the DWD (for unemployment insurance) and the DOR (for combined state and county withholding tax), most commonly through Indiana's INBiz online business registration portal.
During registration, you'll generally need information such as:
- Legal business name
- Federal Employer Identification Number (EIN)
- Business entity type
- Business address
- Owner or responsible party information
- Date employees first performed services in Indiana
- Estimated payroll information
Once registered, you'll receive a DWD UI account number and a separate Indiana Taxpayer Identification Number (TID) for combined state and county withholding.
How to File Indiana Payroll Taxes
Filing payroll taxes in Indiana involves managing unemployment insurance separately from a combined state-and-county withholding filing. A typical filing process includes:
Step 1: Calculate Employee Wages
Determine each employee's gross wages, including regular pay, overtime, bonuses, commissions, and other taxable compensation.
Step 2: Determine Each Employee's County of Residence
Confirm each employee's Indiana county of residence as of January 1, and identify the applicable county tax rate from the DOR's current Departmental Notice #1.
Step 3: Calculate Payroll Taxes
Determine your employer UI contribution based on your current DWD rate, and calculate employee withholding for the flat state income tax rate plus the applicable county rate.
Step 4: Withhold Employee Taxes
Deduct state income tax and county income tax from each paycheck.
Step 5: Pay Employer Contributions and Remit Withholding
Pay employer UI contributions to the DWD, and remit combined state and county withholding to the DOR.
Step 6: File Payroll Tax Returns
Submit quarterly UI wage reports to the DWD, and periodic combined state/county withholding returns to the DOR.
Step 7: Maintain Payroll Records
Keep detailed payroll records, wage information, and payment confirmations in case of future audits or compliance reviews from either agency.
Following a consistent payroll process helps reduce mistakes and makes year-end reporting significantly easier.
Frequently Asked Questions
Who is required to pay Indiana payroll taxes?
Most businesses that hire employees in Indiana are required to register with the DWD and the DOR, and to withhold both state and county income tax for every employee based on their county of residence. Your responsibilities may include paying employer UI contributions, withholding state and county income tax, filing returns, and maintaining payroll records.
What payroll taxes are employers responsible for in Indiana?
Indiana employers generally have responsibilities related to unemployment insurance (employer-paid), state personal income tax withholding at a flat rate, and county income tax withholding, which applies to every employee based on their specific Indiana county of residence. Indiana has no state disability insurance program.
How often do employers file Indiana payroll tax returns?
Unemployment insurance is reported quarterly to the DWD. State and county income tax withholding are filed together on a schedule based on the amount withheld monthly, quarterly, or annually.
How do I register for Indiana payroll taxes?
Employers register with the DWD (unemployment insurance) and the DOR (combined state and county withholding), most commonly through Indiana's INBiz online registration portal, once they hire their first Indiana employee.
What happens if payroll taxes are filed late?
Late filings or payments may result in penalties, interest charges, or other compliance issues, and a higher delinquent UI rate can apply to employers who consistently pay late. Filing accurately and on time with both the DWD and DOR helps reduce the risk of unnecessary costs.
Does Indiana payroll tax apply to remote employees?
Yes, and county tax specifically follows the employee's county of residence rather than the employer's location so a remote employee living in one Indiana county owes that county's tax rate regardless of where the employer is based. Employers should also confirm broader Indiana nexus and UI obligations for any remote or multi-state employees.
Are Indiana payroll tax rates the same every year?
Not always. Indiana's flat state income tax rate has been decreasing under a multi-year phase-down (2.95% for 2026, with a further drop to 2.90% scheduled for 2027), and individual county rates are reviewed and can change annually several counties adjusted their rates for 2026. UI rates depend on each employer's own experience. Employers should review the DOR's current Departmental Notice #1 and their DWD rate notice each year before processing payroll.
Can payroll software calculate Indiana payroll taxes automatically?
Many payroll platforms automatically calculate Indiana UI contributions, flat-rate state income tax withholding, and the correct county tax rate for each employee's county of residence, and help employers meet filing deadlines. Given that county tax applies almost universally across Indiana, this kind of automation is particularly valuable here though employers are still responsible for ensuring payroll information is accurate and up to date.
