What is the 'cost basis' of your crypto futures position?

Understanding Cost Basis in Crypto Futures

1. Cost basis in crypto futures refers to the original value assigned to a position for accounting and tax purposes. It is not simply the entry price but includes all associated transactional costs incurred when initiating the position.

2. Unlike spot market purchases, futures positions involve margin, funding rates, and potential rollover fees — each of which may influence how cost basis is calculated depending on jurisdiction and accounting method applied.

3. Exchanges typically do not compute or report cost basis for futures trades automatically. Traders must manually track entries, exits, adjustments, and fee allocations across multiple contracts and expiries.

4. In jurisdictions like the United States, the IRS treats futures under Section 1256 contracts, mandating mark-to-market accounting at year-end. This requires recalculating unrealized gains or losses based on settlement prices — effectively resetting cost basis for tax reporting purposes.

Components That Adjust Cost Basis

1. Initial margin deposit is not part of cost basis; only actual realized cash flows tied directly to opening or closing the position count.

2. Commissions paid to brokers or exchanges during order execution are added to the cost basis of long positions and subtracted from proceeds for short positions.

3. Funding payments received or paid while holding perpetual futures positions do not alter cost basis — they are treated as separate income or expense items under most tax regimes.

4. Rollover costs incurred when shifting exposure from an expiring contract to a new one can be capitalized into the new position’s cost basis if documented properly and permitted by local guidance.

Impact of Position Type on Calculation

1. For long futures positions, cost basis starts with the entry price plus commissions and any applicable exchange fees, then adjusts upward for subsequent margin calls met with additional deposits that increase economic exposure.

2. Short futures positions use a mirrored logic: proceeds from initial sale minus commissions form the baseline, with later margin top-ups potentially increasing the effective cost of covering.

3. Hedged positions involving simultaneous long and short legs require segregation — each leg maintains its own independent cost basis unless formally designated as a hedge under regulatory frameworks like ASC 815.

4. Cross-margin accounts introduce complexity because funds move dynamically between positions. Accurate cost basis tracking demands granular ledger reconciliation rather than relying on wallet-level balances.

Tax Reporting Implications

1. Under U.S. tax law, 60% of gains or losses from regulated futures contracts are taxed at long-term capital gains rates, and 40% at short-term rates — regardless of actual holding period.

2. Mark-to-market rules force recognition of unrealized PnL annually, meaning cost basis must reflect fair market value on December 31st, even if no trade occurred that day.

3. Foreign traders subject to local VAT or GST regimes may need to treat certain fees embedded in futures pricing as taxable inputs — altering net cost basis for input tax credit calculations.

4. Failure to maintain contemporaneous records of trade confirmations, fee statements, and settlement reports can result in disallowed deductions or recharacterization of income by tax authorities.

Frequently Asked Questions

Q1: Does leverage affect cost basis?Leverage itself does not change cost basis. Only actual cash outflows such as commissions, fees, and margin top-ups tied directly to trade execution contribute to cost basis computation.

Q2: Can I average cost basis across multiple futures entries?No. Futures positions are not eligible for averaging methods like FIFO or LIFO used in spot markets. Each contract leg must be tracked individually due to differing expiries, underlying indexes, and settlement mechanics.

Q3: Is funding rate income included in cost basis?Funding rate receipts or payments are reported separately as ordinary income or expense. They do not adjust the cost basis of the underlying futures position.

Q4: What happens to cost basis when a futures contract expires worthless?If a long position expires with zero settlement value, the full cost basis becomes the deductible loss amount. For shorts, the cost basis determines the gain realized upon final settlement at zero.
