Not through anything exotic — through proceeds treated as income, a basis nobody chased, and a carryover lost in a software switch. All three are avoidable, and all three are handled here.
A 1099-B reports what you sold for. Taxing that figure instead of your gain overstates a return by the entire cost of the investment — and it is the single most expensive mistake in self-filed returns with trading.
Short against short, long against long, then against each other, with the $3,000 annual loss limit applied and the remainder carried forward — and recorded on your file so next season claims it automatically.
Where your broker didn't report basis we carry the lot at zero — the IRS's own assumption, and the worst case for you — and say so loudly. Getting the real figure from the supplemental statement is usually the biggest correction on the whole return.
Box 1b is part of box 1a, never added to it. The qualified dividends and capital gain worksheet stacks preferential income on top of ordinary income at 0%, 15% and 20% — we run it exactly, and show you what it saved.
Every sale, swap and spend of a digital asset is a disposition. Exchanges often issue no 1099-B at all, so your CSV is the record of account. Staking, mining and airdrop rewards are ordinary income and we keep them out of Schedule D on purpose.
3.8% on the lesser of your net investment income or your income above the threshold. Computed, explained, and shown as its own line rather than folded silently into the total.
Per-property income, every expense category, depreciation, the personal-use limit, and the $25,000 active-participation allowance with its phase-out.
Capital losses, charitable carryforwards, passive losses. We record them on your file, and the following year they're already there.
Drop your broker's 1099-B or a crypto CSV and we'll read every row.
