Automate exports from platforms, then reconcile with a private spreadsheet or specialized app. Name files systematically by date, asset, and counterparty. Back up to two locations. Ten minutes weekly prevents year‑end chaos and eliminates guesswork if a counterparty disappears or rebrands. One reader avoided an audit adjustment after producing a tidy, dated folder that matched on-chain records within minutes.
Record purchase price, fees, and any rebates to establish accurate basis. When assets are received without purchase, capture fair value at receipt for income reporting. Consistent timestamps and reference rates make future gain calculations defendable, even when platforms vanish or merge.
Prefer machine‑readable exports plus human‑readable confirmations. Screenshots alone can be challenged, but paired with signed contracts, transaction hashes, and bank statements, they paint a persuasive, time‑anchored record. Highlight currency, time zone, and identity fields to neutralize ambiguity during reviews.
If you receive tokens, points, or rights for participating, promoting, validating, or simply holding, many jurisdictions treat fair value at receipt as taxable income. Mark the timestamp and valuation source, and reserve cash for taxes so you are never forced‑to‑sell.
Swapping one asset for another can trigger taxes even without touching fiat. Track proceeds, basis, and fees to compute gains or losses. Holding period often changes rates, rewarding patience. Document intent and economic substance to support positions if rules appear unsettled locally.
Losses can offset gains, subject to jurisdictional caps. Reacquiring similar positions too quickly may jeopardize deductions under certain instruments, though treatment varies, especially for crypto. Keep cooling‑off intervals, capture rationale, and consult guidance to avoid rebuilding risk without tax relief.
