Filing taxes in the United States has never been simple, and when you add crypto transactions into the mix, it becomes even more complicated. For 2025, the IRS has tightened reporting rules on digital assets, requiring taxpayers to disclose any activity with Bitcoin, Ethereum, stablecoins such as USDT and USDC, or DeFi protocols.
The problem? Many investors confuse the reporting requirements for Bitcoin versus stablecoins. Some think stablecoins aren’t taxable because they’re pegged to the dollar. Others believe that small Bitcoin transactions don’t need to be declared. Both assumptions are wrong — and costly.
This article highlights the most common mistakes crypto users make when filing their IRS returns, explains the differences between Bitcoin and stablecoins, and gives you practical strategies to stay compliant. For a dedicated breakdown on stablecoins, check out our guide: How to report USDT and USDC on IRS taxes in 2025.
Why Bitcoin and Stablecoins Are Taxed Differently
Bitcoin is primarily seen as an investment asset, often held long-term, and subject to capital gains rules. Stablecoins, however, are designed for spending and liquidity, so they generate more frequent taxable events. Swapping USDC for Bitcoin, paying a bill with USDT, or moving between stablecoins all count as disposals in the eyes of the IRS.
The bottom line: whether you use Bitcoin as “digital gold” or stablecoins as “digital cash,” every taxable event must be reported.
Common Mistakes to Avoid
Mistake 1 – Treating Stablecoins as Tax-Free
Stablecoins mirror the U.S. dollar, but they’re still considered property by the IRS. Disposing of them — even for a $1 gain — creates a taxable event.

Spending Bitcoin on coffee or sending $50 to a friend counts as a disposal. The IRS expects every transaction to be reported, no matter how small.
Mistake 3 – Mixing Wallets Without Tracking
Transfers between wallets are not taxable, but losing track of cost basis is dangerous. If you cannot prove acquisition value, the IRS may assume zero basis and tax the full withdrawal.
Mistake 4 – Misreporting DeFi Yields
USDC interest from lending, or BTC staking rewards, are treated as ordinary income, not capital gains. Forgetting this often triggers IRS corrections.
Mistake 5 – Relying Only on Exchange Reports
Coinbase, Binance, and other exchanges don’t track your DeFi activity or wallet swaps. Use software aggregators like CoinTracker, Koinly, or TokenTax to consolidate.
