Can I swap Bitcoin in United States legally?

Yes — every venue in our fee table holds the required regulatory authorisations in United States. Always verify the venue's current registration status before signing up.

What's the cheapest way to swap Bitcoin in United States?

Among the venues we track, the cheapest path is typically the lowest-fee funding rail on the venue's full-trading-view interface. Simple-Buy interfaces and card-funded transactions cost materially more (1.5-3%+ all-in). See the fee comparison above for current rates.

Is disposing of Bitcoin a taxable event in United States?

Yes — most disposal-class actions (sell, swap, send-as-payment) trigger a taxable disposal at fair-market value on the action date. See the tax-primer link above for the United States framework + edge cases.

What documents do I need to swap Bitcoin in United States?

Standard KYC at every venue: government photo ID (driver's licence or passport), tax identification, and proof of address (utility bill or bank statement under 90 days). Verification typically completes within 5-30 minutes; manual review for edge cases takes 1-3 business days.

Regulatory framing — United States

CEX swaps are reported on 1099-DA for both sides of the trade (the BTC disposal + the new asset acquisition) starting tax year 2025+, with cost-basis from 2026+. DEX swaps are NOT covered by the IRS broker reporting regime — you must self-track on Form 8949 (this is a known gap that 2025+ legislation has periodically threatened to close, but as of 2026-06-02 DEX swaps remain self-reported). EVERY swap is a taxable disposal regardless of whether you exit to fiat. The 'I didn't cash out so it's not taxed' fallacy is the most common + expensive misconception in crypto-tax filing.

Common gotchas

BTC-to-stablecoin swap = full taxable disposal. Even swapping $10,000 of BTC for $10,000 USDC triggers capital-gains calculation against your BTC cost basis. The stable destination doesn't matter — the disposal of BTC at FMV is what's taxed.
DEX swaps via WBTC: you must FIRST convert BTC to WBTC (wrapped Bitcoin on Ethereum), which is itself often custodial bridging — adding counterparty risk. The bridging is also a potential taxable event depending on how the bridge is structured.
Cross-chain bridges (e.g., BTC → ETH-side WBTC → ETH on Uniswap → back to BTC via wrap/unwrap) can chain MULTIPLE taxable events. A single 'I want to swap BTC for ETH' trip can produce 3-4 reportable disposals if it routes through bridges.
CEX 'Convert' tools (Coinbase Convert, Kraken Instant Convert) typically charge 1.5-2.5% spread — significantly more than the same swap via the Pro/Advanced trading interface (0.4-0.6%). For swaps > $500, use the Pro interface. The UI tradeoff: less convenient, much cheaper.
Tax-lot selection matters for swaps just as for sells. The BTC lot you're disposing affects your capital-gain calculation. Specific-identification is permitted; default is FIFO. Crypto-tax software can model the difference.

Step-by-step

Decide: CEX (custodial) or DEX (non-custodial). CEX = simpler, cheaper for BTC→anything, 1099-DA reported. DEX = requires WBTC bridging + extra cost, but no KYC + access to long-tail tokens. Most retail users want CEX.
Pick the venue + verify state availability. All 4 CEXes listed serve US retail; Uniswap is non-restricted but you'd need a non-custodial wallet + initial WBTC supply.
Execute the swap on the Pro/Advanced tier if available. Spread on Pro vs Simple is ~1% per side. For any swap > $500, this delta is meaningful. The UI is more complex (order book vs single-click) but the cost savings are real.
Record the trade for tax purposes. 1099-DA from 2025+ reports CEX swaps automatically. For DEX swaps, manually log: BTC amount sent + FMV at swap date + asset received + new cost basis. Crypto-tax software helps.
Verify the received asset is in your account / wallet. CEX swaps are instant in your account balance. DEX swaps: wait for at least 1 confirmation. Bridge swaps: wait for bridge finality on both sides (can take minutes to hours).
Decide on holding location. If the received asset is long-term hold: withdraw to self-custody. If it's for active trading: leave on venue. If it's a stablecoin for spending: consider keeping on the venue's debit-card linked account.

Tax summary

Swapping BTC for any other asset IS a taxable disposal of the BTC at fair-market value on swap date. Capital gain/loss = sale FMV - cost basis. The asset received establishes a NEW cost basis = swap-date FMV. Short-term (≤365d holding) vs long-term (>365d) rates apply. 1099-DA from 2025+ reports CEX swaps; DEX swaps must be self-reported on Form 8949. See /crypto-taxes-us/.
