How to Prepare Your Tax Records for Crypto If Congress Acts This Year

Prepare now: don’t let a sudden crypto tax rule change catch you off-guard

If Congress moves on the draft crypto bill introduced in January 2026, many investors and tax preparers will face new or clarified reporting duties almost overnight. That would mean new definitions for when tokens are securities or commodities, expanded broker reporting and potential changes to how stablecoin interest and certain DeFi flows are taxed. For investors and preparers who already struggle with incomplete transaction histories, mismatched cost-basis and missing 1099s, the next step is simple: get your books in order now.

Why this matters in 2026 — the likely ripple effects

Late January 2026 saw U.S. senators unveil draft legislation designed to bring long-awaited clarity to crypto markets. The bill proposes to define token classification (security vs. commodity), assign primary market oversight to the CFTC for spot markets, and refine rules around stablecoins. If enacted, these changes could trigger:

• New or standardized 1099-style reporting obligations for exchanges, custodians and decentralized platforms.
• Stronger broker-dealer and custodian duties to collect cost-basis data and issue corrected statements.
• Regulatory reclassification that changes how specific tokens are taxed or reported.
• Heightened IRS scrutiny and wider data-sharing between regulators and tax authorities.

Those outcomes matter because tax compliance is already the most common pain point for crypto holders. The right records today reduce audit risk, speed filings and preserve planning options if rules change.

Top-line playbook (inverted pyramid)

Start with three priorities: 1) capture every transaction and backup immutable proofs, 2) reconcile exchange 1099s and on-chain records, 3) document your accounting policy and hold a reproducible audit trail. Below is a practical, time-phased checklist that tax preparers and investors can implement this quarter.

Immediate (0–30 days): Lock down raw records

When legislation is plausible, act fast. These are high-leverage, low-effort items you can complete in days.

• Export every exchange and custodial report (CSV/JSON/PDF). Include complete trade history, deposits/withdrawals, fee lines and staking or interest payments. Get reports from all platforms you used in 2018–2025 and 2026 YTD.
• Snapshot wallet states for all on-chain addresses: token balances, contract interactions, and token IDs for NFTs. Save transaction IDs (txids) and block timestamps as immutable proof.
• Download on-chain receipts (raw transaction hex or signed messages) and maintain a hash of each export to show data integrity over time.
• Collect KYC proof that links accounts/wallets to taxpayers: exchange account registration emails, IP logs if available, and signed wallet ownership statements (e.g., sign a message from the address).
• Request missing 1099s now from any exchange that didn’t issue a form. Document your outreach (support tickets, emails, call logs).
• Preserve trade confirmations and bank statements that show transfers to/from exchanges (for tracing funds).

Short-term (30–90 days): Reconcile and choose methods

This phase turns raw data into a reconciled ledger you can defend.

• Reconcile exchange reports with on-chain activity. Flag mismatches and keep a reconciliation worksheet that shows source, correction and rationale.
• Select and document your cost-basis method (FIFO, LIFO, Specific Identification). If you intend to use Specific ID, create procedures for how you tag and retain lot-level evidence.
• Tag transaction types: trade, spend, transfer, airdrop, airdrop-received-as-income, fork, staking reward, lending interest, liquidity deposit/withdrawal, NFT mint, NFT sale, gas, and fee. Accurate tagging avoids classification errors later.
• Quantify staking and lending income with timestamps and USD value at receipt. Preserve exchange or protocol statements showing how returns were calculated.
• Use accounting software built for crypto (CoinLedger, TokenTax, Koinly, or tax-module of your choice). Export and version-control work product.

Mid-term (3–6 months): Deep-dive into complexity

Now you address DeFi, derivatives and edge cases that trigger the most IRS scrutiny.

• Reconcile DeFi protocols and derive USD values at each step. For swaps inside pools, document impermanent loss calculations and the basis allocation for token pairs.
• Document airdrops, forks and promotional tokens with source code or protocol announcements to prove receipt timing and intent.
• Compile NFT provenance: mint receipts, creator invoices, gas paid, and the USD value at sale or transfer.
• Run chain analytics on large or suspicious flows to establish sources—use tools like Chainalysis, Nansen or custom Etherscan queries. Save the reports in your audit binder and consider complementary analytics described in independent tooling writeups.
• Model the impact of token reclassification by preparing parallel tax position summaries under both “commodity” and “security” treatments for significant positions.

Pre-filing season (6–12 months): Finalize returns and archive

At this stage you prepare for actual filing and post-change compliance.

• Produce a master tax summary that lists realized gains/losses, unrealized positions, income types and supporting evidence for each line item.
• Create client-ready schedules with explanatory notes for any large or unusual transactions.
• Archival and retention: store CSVs, blockchain snapshots and forensic reports in a secure, timestamped cloud archive (retention: at least seven years, or longer if the position is large). See a related retention & contract checklist for digital evidence management.
• Plan amendments or disclosures if the new law requires reclassification or retroactive reporting; draft templates for taxpayer consent and amendment filings.

Audit-readiness checklist (what to include in the binder)

IRS examiners focus on provenance and reproducibility. Your binder should let a third party reproduce the tax position from raw data to return entry.

• Master transactions CSVs and checksum-hashed exports.
• Reconciliation workbook showing adjustments and justifications.
• Statements from exchanges and custodians (1099s, transaction logs).
• Signed wallet ownership statements and KYC docs.
• Third-party chain analytics reports (PDFs) for major transfers.
• Method statement: chosen cost-basis method and how it was applied.
• Correspondence log for missing or corrected 1099s.
• Documentation for staking, lending and rewards—how and when income was recognized.

Rule of thumb: If you cannot trace a transaction from the source to the tax return with three independent records, assume the IRS will question it.

Folder and naming conventions — simple, consistent, defensible

Spend one afternoon to create a standard folder template that you reuse for all clients or your own accounts. Consistency saves hours during an audit.

• Top-level: /2026-TAX-FILES/ClientName-or-Self/
• Subfolders: /Raw-Exports/, /On-Chain-Snapshots/, /Reconciliations/, /Chain-Analytics/, /1099s/, /Audit-Binder/
• File naming: YYYYMMDD_platform_type_account.csv (e.g., 20260112_binance_trades_ACCT123.csv)

Advanced strategies for preparers and sophisticated investors

These are higher-touch options that can reduce tax friction or enhance defensibility. Discuss with a CPA or tax attorney before implementing.

• Entity-level consolidation: move trading into an entity (LLC or S-corp when appropriate) to centralize reporting—consider state and self-employment tax implications.
• Specific-identification software workflows to control lot selection for large portfolios with thin tax lots.
• Mark-to-market (MTM) election for traders who meet the IRS trader in securities criteria—pros/cons vary if tokens are reclassified as securities.
• Preemptive disclosures for complex DeFi strategies: create a short memo for future examiners describing the protocol, your role, and the valuation approach.
• Tax-loss harvesting automation: use software and stop-loss strategies but plan around potential crypto wash-sale extensions if Congress adopts them; review automation and cost-optimization patterns when designing workflows.

Common pitfalls and how to avoid them

Learn from the most frequent mistakes we see in 2025–2026 filings.

• Mismatched basis: failing to include fees or the USD value at acquisition leads to understated basis—always include fees and timestamped USD conversions.
• Relying solely on exchange 1099s: exchanges have been late or incorrect—reconcile everything to on-chain evidence.
• Ignoring small transfers: repeated small transfers (microtrades) can aggregate into large taxable events—track them systematically.
• Mixing personal and business wallets: separate wallets and accounts, or be ready to show how you allocated transactions between activities.
• Under-documenting DeFi flows: protocol-level complexity requires more, not less, documentation—save contract addresses and exact function calls.

If Congress passes the bill — triggers and rapid-response playbook

Legislation may include effective dates, retroactivity clauses, or phased implementation. Prepare a rapid-response checklist your firm or household can implement within 72 hours of an announcement.

1. Identify all positions affected by reclassification (security vs. commodity) and mark them in your master spreadsheet.
2. Flag positions requiring new reporting thresholds or new 1099 types.
3. Send templated client advisories explaining how to collect missing docs and what additional information you will need.
4. Run automated scripts to re-price historical transactions to any newly-prescribed valuation approach (e.g., midpoint of bid/ask vs exchange trade price).
5. Prepare amendment templates and legal memos if retroactive reporting or lookback provisions are enacted.

Practical templates to implement today

Use these quick templates to get started—copy into your cloud drive and adapt them.

• Transaction Reconciliation Template: columns: txid, timestamp, from, to, token, amount, USD at timestamp, fee, source file, comment, reconciled (Y/N).
• 1099 Request Log: columns: exchange, year, form type requested, date requested, ticket #, status, follow-up date.
• Audit Binder Index: list of documents with file path, checksum, and short description.

When to call a specialist

If any of the following apply, engage a CPA or tax lawyer experienced in crypto:

• Positions > $1M or concentrated exposure to tokens prone to reclassification.
• Extensive DeFi, derivatives or cross-chain bridging activity.
• International exposure with FBAR/FATCA implications.
• Prior audit or IRS correspondence related to crypto.

Key takeaways — what to do this week

• Export and snapshot everything—exchange CSVs, wallet snapshots, and 1099s. Don’t assume they’ll be available later.
• Reconcile exchange reports with chain data and maintain a reconciliation worksheet.
• Document cost-basis policy and tag every transaction by type.
• Archive an audit binder with checksums and signed wallet ownership proof.
• Plan for reclassification by modeling tax outcomes under multiple regimes and preparing amendment templates.

Final note: Congress may or may not pass the draft in 2026, but the one certainty is increased attention to crypto tax reporting. The investors and preparers who act now — standardizing exports, reconciling ledgers and creating reproducible audit trails — will be far better positioned to comply quickly and defend their positions.
