Quick Answer: On a $100,000 capital gain, Indiana's flat 2.95% state tax adds $2,950.00 to your bill, leaving $97,050.00 after state tax.
The State Rate Is Only Part of an Indiana Bill
Indiana applies one statutory rate, 2.95%, to a realized capital gain, and the calculator returns $2,950.00 on the default $100,000 gain with $97,050.00 retained. Effective rate and marginal rate are both 2.95%: on a flat schedule the last dollar of gain is taxed identically to the first.
The state rate is not the whole Indiana liability, and this calculator models only the state rate. Indiana counties levy their own local income tax on the same base, at rates that differ by county of residence, and none of that is in the figure above. calculateStateCapitalGains reads a single standardRate from the state table and multiplies; there is no county field in the input set and no county term in the code. Treat $2,950.00 as the state component of a two-part bill.
One further caveat about provenance, because it belongs on the page rather than in a commit message. The 2.95% figure carries a bracketVintage marked UNVERIFIED in the engine's own 2026 table: it is the rate the statutory phase-down schedule under IC 6-3-2-1(b) points to for 2026, but it could not be confirmed against an Indiana Department of Revenue source when the table was last checked. Every other flat-rate state in the file has a confirmed 2026 citation; Indiana does not.
How This Is Calculated
Indiana taxes a capital gain at a flat 2.95% at the state level, the product of a multi-year rate phase-down. Note what this page does not include: Indiana counties levy their own local income taxes on top, which vary by county of residence and are not part of this calculation.
That makes the state computation a single multiplication, with the effective rate falling straight out of it.
The full sequence:
- Start with the net gain. Capital losses and loss carryforwards are netted first; what you enter is the net figure.
- No preferential rate. Indiana has no separate capital gains rate and no long-term holding-period break, so the gain is taxed exactly as wages would be.
- Apply the rate. Multiply the net gain by 2.95%. Because the schedule is flat, your other income does not push the gain into a higher band, and the calculator does not need to stack the two.
- Effective rate. Total tax divided by realized gain, which on a flat schedule returns 2.95% at every gain size. Effective and marginal rates are the same number here.
- Net proceeds. Subtract the state tax from the gain to get what you keep before federal tax.
Worked Example
Consider an investor in Indiana who realizes $100,000 in capital gains from a single asset sale during the year.
- Identify the gain. The full $100,000 capital gain is added to gross income, since Indiana taxes capital gains at the same statutory rate as wages and other ordinary income, with no separate preferential rate for long-term holdings.
- Apply the flat rate. Indiana's statutory individual income tax rate is a uniform 2.95%, applied to the entire gain regardless of the investor's total income or how long the asset was held.
- Compute the tax due. $100,000 × 2.95% = $2,950.00, the state tax liability on this sale.
- Net proceeds. Subtracting the $2,950.00 state tax from the $100,000 gain leaves the investor with $97,050.00 in state after-tax proceeds, before any federal capital gains tax is applied separately.
Because Indiana applies one flat rate to every dollar of gain, the effective state tax rate here equals the statutory rate itself: 2.95%.
What the Twelve-Row Table Shows
The table under the calculator holds other income fixed and sweeps the gain from one sixth of your entry to twice it. On the defaults that runs $16,666.67 to $200,000.00, and the tax column runs $491.67 to $5,900.00 in a perfectly straight line, passing through $2,950.00 at the $100,000 midpoint. Every row divides to the same 2.95%.
No bracket edge exists to walk. Indiana's schedule is a single band from the first dollar upward, so there is no threshold in this sweep and none anywhere outside it. The useful statement is the negative one: realizing a gain in two tax years rather than one saves nothing in Indiana state tax, because there is no lower band for the first slice to fall into. The same split can still matter federally, where brackets do exist.
Cost of the next unit. Each additional $1,000 of gain adds $29.50 of Indiana tax. Move the input from $100,000 to $101,000 and the headline goes from $2,950.00 to $2,979.50. At the top of the sweep the increment is the same $29.50, which is why the chart is a line rather than a curve.
Working backwards from a tax budget. A $5,000 Indiana tax bill corresponds to a gain of $169,491.53; entering that figure returns exactly $5,000.00. A $10,000 bill corresponds to roughly $339,000, where the calculator returns $10,000.50. This division is only valid because the rate is constant, and it is the reason the reverse question is trivial here and is not trivial on the Kansas or Maine equivalents of this page.
Right base against wrong base, priced. The error that costs the most is running the sale price through the calculator instead of the net gain. A property bought for $300,000 and sold for $400,000 produces a $100,000 gain and $2,950.00 of tax. Enter $400,000 in the gain field and the calculator returns $11,800.00, overstating the Indiana bill by $8,850.00. Nothing in the engine can catch this: the input is a number, and $400,000 is a perfectly valid gain.
The mirror-image error is subtracting the state tax twice, once here and again from a federal calculator's net figure. The $97,050.00 this page reports is the gain less Indiana tax only. Federal tax, the 3.8% net investment income surtax, and any county income tax all still come out of that same $97,050.00.
What This Does Not Account For
While this calculator provides penny-exact state statutory modeling, additional federal and transactional complexities warrant supplementary review: - Federal Capital Gains Taxes: Federal long-term brackets (0%, 15%, 20%) and short-term ordinary rates up to 37% under IRC § 1. - Net Investment Income Tax (NIIT): The 3.8% surtax on net investment income under IRC § 1411 for single filers over $200,000 (married joint over $250,000). - Alternative Minimum Tax (AMT): Federal AMT calculations under IRC § 55 impacting incentive stock option (ISO) exercise spread. - Section 1031 Like-Kind Exchanges: Tax deferral mechanisms for real property held for productive use in trade, business, or investment. - Qualified Small Business Stock (QSBS): Federal Section 1202 gain exclusions where state conformity varies significantly.
Common Pitfalls
- Assuming Federal Rate Parity: Most states do not offer preferential long-term capital gains rates; gains are taxed at standard ordinary income rates.
- Failing to Track Holding Periods: Short-term gains (assets held ≤1 year) generate higher federal tax liabilities even if state rates treat both holding periods identically.
- Underestimating Multi-State Apportionment: Selling real estate or business assets located in other jurisdictions triggers multi-state non-resident return filing obligations.
- Neglecting Underpayment Penalties: Substantial one-time liquidity events require prompt estimated tax payments within the quarter of sale to avoid statutory penalties.
- Mismatched Cost Basis Records: Failure to document reinvested dividends, stock splits, or structural return-of-capital distributions leads to inflated taxable gain calculations.
