Most traders treat tax records as a separate problem from journaling. They aren't. The fields your tax software needs are mostly the same fields a good trading journal already captures — if you set it up right from day one.
What every trade record needs for taxes
- Instrument and exchange. Section 1256 contracts (futures, broad-based index options) get the 60/40 split. Equities don't. Mixing them in one row is a filing nightmare.
- Open and close timestamps. Drives holding period — short-term vs long-term.
- Proceeds, cost basis, and fees separately. Net P&L is convenient for review but useless on Form 8949.
- Counter-trade links. Wash sale flags require knowing which loss matches which subsequent buy.
Mark-to-market election (if applicable)
If you qualify for trader tax status and elect mark-to-market (Section 475(f)), wash sale rules vanish and losses become ordinary. The election locks in early in the year and reshapes how you should be journaling. Talk to a CPA — but make sure your journal exports both treatments cleanly.
Crypto and FX caveats
Spot FX defaults to Section 988 (ordinary). Spot crypto is property — every disposal is a taxable event, including crypto-to-crypto swaps. If you're trading either, your journal needs a USD-equivalent basis at the timestamp of every trade.
What to export
By the last week of December, export a CSV with: date, instrument, side, quantity, proceeds, cost basis, fees, asset class. Sort by asset class first, then date. That single file feeds TurboTax, TradeLog, or your CPA's intake — no reconstruction required.
How Pro Journal Trader helps
Every logged trade carries the fields above. End-of-year CSV export is one click. The annual review takes minutes because the discipline happened all year.
