The Indiana state tax on an early 401k withdrawal is a flat 2.95% for the 2026 tax year, plus a county income tax of roughly 0.5% to 3% depending on where you live. Indiana does not add its own penalty for pulling money out before retirement age. The federal government does: a 10% additional tax on most distributions taken before age 59½, layered on top of regular federal income tax. Once you stack everything together, 30% or more of the withdrawal can disappear before it reaches your bank account.
How Indiana Taxes the Withdrawal
Indiana taxes all income at a single flat rate. For 2026 that rate is 2.95% of adjusted gross income, and a 401k distribution is treated exactly like wages.1Indiana General Assembly. Indiana Code 6-3-2-1 – Imposition of Tax; Tax Rate; Calculation and Certification of Individual Adjusted Gross Income Tax Rate The state starts its calculation with your federal adjusted gross income, which already includes the distribution. There is no separate Indiana penalty, no multiplier for early withdrawals, and no graduated bracket.
On a $10,000 early withdrawal, the state portion alone comes to $295.
Your County Tax Adds to the State Rate
Every Indiana county levies its own income tax, and it applies to your 401k withdrawal too. County rates for 2026 run from 0.5% at the low end to 3% at the high end.2Indiana Department of Revenue. Indiana County Income Tax Rates The rate you owe is based on where you lived on January 1 of the tax year.
Combined with the 2.95% state rate, your total Indiana bite lands somewhere between roughly 3.45% and 5.95%. On that $10,000 withdrawal, a resident of a county with a 2% local rate owes $295 to the state and $200 to the county, for $495 in Indiana taxes.
The Federal Layer Is Where It Really Hurts
State and county taxes are only part of the picture. The IRS treats a 401k distribution as ordinary income at your marginal federal rate, which can be anywhere from 10% to 37%. If you are under 59½, federal law adds a 10% additional tax on the taxable portion.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts
Someone in the 22% federal bracket taking $10,000 early faces $2,200 in regular federal tax plus a $1,000 penalty, for $3,200 in federal taxes alone. Add Indiana state and county taxes on top and the total can easily reach $3,700 or more on that same $10,000.
Exceptions That Waive the 10% Federal Penalty
Several situations let you avoid the federal 10% additional tax even when you withdraw before 59½. The most common ones for 401k plans include:4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
- Leaving your job during or after the year you turn 55, taking distributions from that employer’s plan. Public safety employees qualify at age 50.
- Total and permanent disability.
- Substantially equal periodic payments taken at least annually over your life expectancy, which you must continue for at least five years or until age 59½, whichever is later.
- Distributions to a former spouse under a qualified domestic relations order.
- Unreimbursed medical expenses that exceed 7.5% of your adjusted gross income.
An exception only removes the extra 10%. Regular federal income tax and the full Indiana state and county tax still apply.
Roth 401k Money Is Treated Differently
If the withdrawal comes from a designated Roth 401k, the tax picture shifts. Your original contributions were already taxed, so the contribution portion of a withdrawal is tax-free at both the federal and Indiana level. Only the earnings are taxable when the distribution is non-qualified (generally, when you are under 59½ or the account has been open less than five years).
A non-qualified Roth 401k payment is treated as a proportional mix of contributions and earnings. The earnings share is subject to regular federal income tax, the 10% federal penalty, and Indiana’s flat 2.95% state rate plus your county rate. If you have been contributing for years and the account is mostly contributions, the taxable slice can be much smaller than it would be from a traditional 401k.
A 60-Day Rollover Erases the Tax
If you deposit the full distribution into another qualified retirement account or IRA within 60 days, the entire amount becomes tax-free.5Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions No federal tax, no 10% penalty, no Indiana state or county tax. The complication is that your plan administrator must withhold 20% for federal taxes before cutting the check, so you have to cover that 20% out of other funds to roll over the full amount. Rolling over only the 80% you received means the missing 20% counts as a taxable distribution.
The IRS can waive the 60-day deadline in narrow circumstances, but waivers are not a plan. If there is any chance you will put the money back, move fast.
Indiana Withholding Is Not Automatic
Here is a detail that catches people off guard. Indiana does not require plan administrators to withhold state or county income tax from retirement distributions. Withholding happens only if you file Form WH-4P with the administrator and specify a flat dollar amount to withhold from each payment.6Indiana Department of Revenue. Income Tax Information Bulletin 13 – Withholding of Adjusted Gross Income Tax on Retirement Pay Skip that form and nothing gets withheld for Indiana, and the full amount comes due when you file.
Many people who take an early distribution end up with a surprise bill the following April because of this. If you are taking a lump sum and did not request state withholding, plan for estimated payments.
You May Owe Estimated Payments
If your withdrawal pushes your total state and county tax liability more than $1,000 above what has already been withheld from wages or other income, Indiana expects quarterly estimated payments.7Indiana Department of Revenue. Estimated Payments Deadlines fall on April 15, June 15, September 15, and January 15 of the following year.
Miss a deadline and Indiana adds a 10% penalty on the underpaid amount for each installment period you missed.8Indiana Department of Revenue. Underpayment of Estimated Tax by Individuals On a $20,000 withdrawal with no state tax withheld, the combined state and county tax can easily top $1,000, and the underpayment penalty piles on 10% of what you should have paid quarterly but did not. If the withdrawal lands early in the year, make an estimated payment by the next quarterly date.
The Full Picture on a $10,000 Early Withdrawal
Putting the numbers together makes the total cost concrete. Take a single filer in the 22% federal bracket, living in a county with a 2% local tax rate, who does not qualify for any penalty exception:
- Federal income tax at 22%: $2,200
- Federal early withdrawal penalty at 10%: $1,000
- Indiana state income tax at 2.95%: $295
- County income tax at 2%: $200
- Total: $3,695
Out of $10,000, you keep $6,305. A higher federal bracket or a higher-tax county leaves you with less. The federal penalty alone accounts for $1,000 of the loss, which is why working through every possible exception before withdrawing is worth the time. Skip estimated payments and file everything the following April and Indiana’s 10% underpayment penalty adds roughly $50 on top of the state and county share.
