Long-Term Capital Gain
Category: Investment · Related form: Schedule D
Gain on assets held more than one year. Preferential 0%, 15%, or 20% rates generally apply, and NIIT may add 3.8% for higher-income taxpayers.
How Long-Term Capital Gain fits 2026 planning
Long-Term Capital Gain sits inside capital gains, dividends, wash-sale timing, and surtaxes such as NIIT that sit beside ordinary brackets. For tax year 2026, US Tax Tools treats year-scoped constants (brackets, contribution limits, wage bases, credit schedules) as separate datasets — so explanations of Long-Term Capital Gain should be read with the same year selected in any linked calculator.
Category focus: Investment. Readers usually land on this page while comparing a paycheck estimate, a credit phaseout, or a retirement contribution room figure that depends on understanding Long-Term Capital Gain first.
Worked example
Stock held 18 months and sold for a $10,000 gain may be taxed at 15% federally if your taxable income sits in the 15% LTCG band.
Treat the example as a teaching sketch, not a filing position. Change filing status, state residency, or mid-year events and the same definition of Long-Term Capital Gain can produce a different cash outcome even when the glossary text stays the same.
What to watch for
Definitions of Long-Term Capital Gain can differ slightly across IRS publications, SSA rules, Marketplace subsidy worksheets, and state agencies. When two programs both say “income,” confirm which modification rules apply — MAGI for one credit is not always MAGI for another.
Legislation and inflation adjustments can move the dollar thresholds around Long-Term Capital Gain without renaming the concept. Prefer the effective date on the primary source (Rev. Proc., SSA notice, USDA table, or state DOR bulletin) over any blog summary — including this one if a later notice supersedes it.
On a filed return, Long-Term Capital Gain most often surfaces around Schedule D. Read the official IRS instructions for that form for the tax year you are filing — glossary pages summarize concepts; they do not replace line-by-line worksheets.
