Form 1099-B reports proceeds from broker transactions — sales of stocks, bonds, options, mutual funds. Brokerages report sale proceeds and cost basis (for covered securities purchased after 2011) to both you and the IRS. Schedule D and Form 8949 summarize these transactions for your tax return. Categories: short-term (held ≤1 year, ordinary rates) vs. long-term (held >1 year, preferential rates). Wash sales are flagged on 1099-B. Crypto transactions face new 1099-DA reporting starting 2026. For active traders, tax software (Koinly, CoinTracker, TaxAct) imports 1099-B data and matches against actual basis. Verify your 1099-B against your records — broker errors are common.
