Illinois tax on collectibles
Illinois is modeled as a flat-rate state (Flat 4.95% state rate). That rate stacks on federal tax for collectibles after asset-class rules.
Federal rules for collectibles: Long-term collectibles (art, many coins, certain metals) face a 28% federal ceiling instead of the usual 20% LTCG cap. Short-term collectibles still use ordinary rates. Holding period still matters for LTCG vs STCG except where a longer QSBS or real-estate test applies.
Open the parent Illinois calculator for a generic sale, or the national Collectibles lander for asset-only copy. Nearby states below keep the same collectibles preset so you can compare residency. Estimates are not tax advice.
Long-term collectibles use a 28% federal ceiling, not the 20% long-term cap. The 3.8% NIIT can still stack when income is high enough. Short-term collectibles stay on ordinary rates.
Illinois is encoded as a flat 4.95% state rate on taxable capital gain. Holding period does not change that 4.95% in this model.
A flat rate makes the state line easier to read than a graduated table: taxable gain times 4.95%. Deductions and retirement subtractions that Illinois allows on a real return are not computed here.

Illustrated tax on a long-term gain
Collectibles held long enough for long-term treatment in Illinois. Investment real estate does not use Section 121 in this table. QSBS uses a more-than-five-year hold.
