Let’s be real: nobody likes tax season. But with DAC8 (Europe) and new IRS 1099-DA rules (USA) going live effectively Jan 1, 2026, "guessing" your numbers isn't an option anymore. Exchanges are now required to share data directly with tax authorities in many regions.
Don't wait for the audit letter. Save this checklist and get your portfolio "audit-proof" this week.
✅ The 2026 Readiness Checklist
1. 📥 The "Grand Export" (Do this NOW)
Don't rely solely on live API connections later.
Task: Download CSV files of your complete transaction history for 2025 from every exchange you used (not just Binance!).Why: APIs can break, and delisted coins often disappear from history logs. Hard copies are your safety net.
2. 🏷️ Fix the "Self-Transfer" Trap
This is the #1 mistake that costs traders money.
The Issue: Moving 1 BTC from your Ledger to Binance is not a taxable event. However, tax software often sees this as a "Deposit" (income) or "Withdrawal" (sale) if not linked.Task: Label all transfers between your own wallets as "Internal Transfer" in your tax software.Result: You avoid paying capital gains tax on money you just moved around.
3. 🆔 KYC & Address Hygiene
With DAC8, cross-border data sharing is automatic.
Task: Ensure your residential address and Tax ID on Binance match your actual current tax residence.Why: If you live in Germany but your old KYC says France, both countries might try to tax you. Clear this up before the automated reports go out.
4. 🕵️ hunt for "Ghost" Cost Basis
Did you buy ETH in 2021 on a now-defunct exchange and move it to Binance in 2025?
The Problem: Binance knows you sold it, but not what you bought it for. The tax man will assume your cost basis is $0, meaning you pay tax on the entire value.Task: Find the original purchase records for any assets you deposited onto centralized exchanges this year.
5. 🇺🇸 US Users Only: The 1099-DA Prep
Task: Watch your inbox. For the first time, brokers may send Form 1099-DA.Action: Compare this form against your own records immediately. If the exchange shows a different "Cost Basis" than your records, you will need to file an adjustment.
💡 Pro Tip: The "Wash Sale" Watch
Note: While crypto wash sale rules are still grey in many jurisdictions, 2026 legislation is tightening.Strategy: Be careful about selling an asset at a loss on Dec 31st and buying it back immediately on Jan 1st. Under new scrutiny, this may be flagged. Consult your CPA.
