How do I get started with crypto tax calculation?

Connect your exchanges using secure API keys, let Moonscape import your transactions, review for accuracy, and generate your tax reports. The whole process takes just a few minutes.

What exchanges do you support?

We support 300+ exchanges including Binance, Coinbase, Kraken, KuCoin, and more. You can also manually upload CSV files from any exchange.

How are crypto taxes calculated?

Crypto taxes depend on your country. In the US, crypto is treated as property with capital gains tax. We calculate your gains/losses using methods like FIFO, LIFO, or Specific ID.

What forms do I need for crypto taxes?

In the US, you'll typically need Form 8949 for capital gains/losses and Schedule D. We generate all the necessary forms with your data pre-filled.

Do I need to report crypto if I didn't sell?

Generally, simply holding crypto isn't taxable. However, trading, selling, earning rewards, or receiving crypto as payment are all taxable events that must be reported.

We use secure API keys (read-only), and never store your private keys or have access to withdraw funds.

Missing Wallets and Phantom Income: Avoid Costly Crypto Tax Mistakes

Learn how missing wallets can cause phantom income traps in crypto. Understand cross-chain detection, how Moonscape alerts you, and how to fix overlooked transactions.

📖 6 min read

You transfer assets across different blockchains using bridges. Weeks later, you see unexpected income in your tax report. Did you realize? Some bridges leave behind hidden transactions that generate phantom income. Many users overlook these transfers, risking costly tax errors and audits.

What Is Phantom Income in Crypto?

Phantom income occurs when you owe taxes on income or gains you didn't realize you had. In cross-chain transfers, this often happens when assets move between wallets or chains without proper tracking. The IRS hasn't provided explicit rules for all bridge scenarios, so gaps exist. If your wallet isn't detected across chains, you might not see or report income correctly.

How Moonscape Detects Missing Wallets and Cross-Chain Moves

Moonscape uses sophisticated algorithms to trace asset movements across multiple blockchains. When you transfer tokens via bridges, our system scans for related transactions, wallet addresses, and token flows. If a transfer occurs but isn't linked to your primary wallet, Moonscape flags it as a potential missed transaction. Our alerts notify you of cross-chain moves that might generate taxable events, even if the wallet isn't directly connected.

How to Fix and Report Missed Cross-Chain Transactions

If Moonscape alerts you about a missing wallet transfer, review the transaction details carefully. Confirm whether the transfer was a taxable event—like swapping assets or withdrawing to a new chain. To fix past omissions, add the transaction manually if needed, or adjust your cost basis accordingly. Keeping detailed records of bridge transactions, including dates, amounts, and chain info, helps ensure accurate tax reporting. If in doubt, consult a CPA familiar with crypto cross-chain activity.

Concrete Example of Phantom Income from Cross-Chain Bridge

Suppose you bridge 1 ETH from Ethereum to Binance Smart Chain (BSC). During the transfer, you pay a bridge fee of 0.01 ETH. Your Moonscape alert flags this transfer. The IRS considers the fee payment as a disposal of 0.01 ETH, which could generate a taxable gain if ETH appreciated. If you didn't report this, you might owe taxes on that small gain—an example of phantom income resulting from a missing wallet link.

Cross-Chain Transfer Tax Considerations

item	characteristic	tax_treatment	notes
Bridge fee payment	Disposal of assets, potential gain	Taxable event (may generate income or gain)	Most professionals agree fees are taxable, but IRS hasn't issued explicit rules.
Asset movement between wallets	No sale, but can trigger phantom income if overlooked	Potential taxable event if it results in a disposal	Detection is key to proper reporting.

Scenario: Bridging ETH to BSC and Overlooking Fees

You transfer 2 ETH from Ethereum to BSC using a bridge.
You pay a fee of 0.02 ETH during the transfer.
Moonscape flags this transfer as a cross-chain move with a fee.
You didn't report this fee as income or gain.

💰 Tax Impact:

The 0.02 ETH fee may be considered a taxable disposal, especially if ETH appreciated. Not reporting it can lead to understated gains and IRS issues.
