L1 vs L2 Network Withdrawal Fee Comparison (Arbitrum, Base, Solana, Lightning)

Q: Does bridging ETH from Ethereum L1 to Arbitrum or Base trigger a taxable swap in Australia?

If you receive a distinct wrapped token or swap assets, it may be treated as a disposal under ATO QC 64902: Every crypto-to-crypto swap, token wrap (ETH to WETH), or DeFi liquidity deposit is a CGT Event A1 disposal valued in AUD and resets the 12-month CGT discount clock; withdrawing directly from your exchange over Arbitrum or Base avoids an on-chain bridge transaction.

Q: Can network gas and exchange withdrawal fees be deducted on ATO myTax Capital Gains Schedule, SMSF Annual Return (SAR) & ATO Data-Matching Protocol (Australia)?

Yes—Australian Taxation Office (ATO) rules allow adding acquisition fees to your cost basis and deducting disposal fees from gross proceeds.
