The world of cryptocurrency taxation is undergoing a pivotal transformation in 2025, bringing both clarity and new responsibilities for investors, traders, and tax professionals. With the introduction of Revenue Procedure 2024-28, the IRS has redefined how cost basis must be tracked across digital assets—shifting from a consolidated, cross-wallet approach to a more structured, wallet-by-wallet (or exchange-by-exchange) model. This change aims to simplify reporting but also introduces critical decisions that could significantly affect your tax liability.
To ease the transition, the IRS has introduced Crypto Safe Harbor provisions, offering temporary flexibility in how taxpayers establish and document their cost basis methodologies. Understanding these rules now isn’t just about compliance—it’s about positioning yourself for smarter tax outcomes in 2025 and beyond.
Understanding the New IRS Crypto Tax Framework
Historically, the IRS treated all your crypto holdings as a single pool when calculating capital gains. This meant that selling one Bitcoin on Exchange A could be considered the sale of your earliest-purchased Bitcoin—no matter which wallet it came from. This "first-in, first-out" (FIFO) default across all accounts created confusion and often led to higher-than-necessary tax bills for those who had low-basis assets buried in old wallets.
Revenue Procedure 2024-28 changes this by requiring taxpayers to track cost basis separately per wallet or exchange. Think of it like managing individual brokerage accounts: gains and losses are calculated within each account independently. This reduces complexity for exchanges and gives individuals more control—provided they make informed choices early.
The Safe Harbor Transition: Two Key Options
To help taxpayers adapt, the IRS introduced a Safe Harbor provision allowing two distinct methods for allocating cost basis during the transition period:
1. Specific Unit Allocation
With this method, you assign specific purchase records (date, amount, price) to specific units of crypto in specific wallets. For example:
- You bought 1 BTC at $30,000 in Wallet A in 2021.
- Another 1 BTC at $40,000 in Wallet B in 2022.
You can explicitly allocate the lower-cost unit to Wallet A and the higher to Wallet B.
✅ Advantage: Full control over which lots are sold, enabling strategic tax-loss harvesting.
❌ Challenge: Requires meticulous record-keeping and consistent tracking.
2. Global Allocation
Here, you apply a uniform rule across all wallets. Examples include:
- Highest cost basis first (HIFO): Minimizes gains now.
- Lowest cost basis first (LOFO): Defers taxes.
- Proportional allocation: Distributes cost basis based on wallet balance size.
✅ Advantage: Simpler to implement and maintain.
❌ Limitation: Less precision in managing taxable events.
Once you choose a method and document it, you cannot switch without losing Safe Harbor protection—a key reason to act thoughtfully before the deadline.
Critical Deadlines You Can’t Afford to Miss
While initial guidance required decisions by January 1, 2025, the IRS granted temporary relief due to ongoing legal challenges. Here’s what you need to know:
- New Decision Deadline: January 1, 2026
You must formally document your chosen allocation method (Specific Unit or Global) by this date. - First Reporting Year: 2026 Tax Filing (April or October 2027)
The new rules apply to transactions occurring in 2025, reported on your 2026 tax return. - Audit Requirement: Keep a signed, dated statement of your method in your records. No need to file it with the IRS—just retain it for audit purposes.
This grace period is valuable—but don’t wait until the last minute. The earlier you organize your data, the better your tax planning will be.

How to Prepare for 2026 Tax Season
Even though filing isn’t due for over a year, proactive preparation today can lead to meaningful tax savings tomorrow.
Step 1: Audit Your 2024–2025 Transaction History
Start by ensuring your records are complete and accurate:
- Reconcile balances across all wallets and exchanges.
- Import missing transactions (e.g., DeFi swaps, NFT trades, staking rewards).
- Verify timestamps, amounts, and cost bases.
Using a dedicated crypto tax platform can automate much of this process, reducing errors and saving hours of manual work.
Step 2: Choose an Accounting Method
Beyond allocation strategy, select a consistent accounting method for each wallet:
- FIFO (First-In, First-Out): Default IRS method if none specified.
- LIFO (Last-In, First-Out): May reduce taxes in falling markets.
- HIFO (Highest-In, First-Out): Ideal for minimizing current-year gains.
Your choice should align with market trends and investment strategy.
Step 3: Plan for Complex Transactions
If you engage in:
- DeFi protocols (liquidity pools, yield farming)
- NFT trading
- Staking or lending
…you’ll need granular tracking capabilities. These activities generate reportable income and capital events that must be captured accurately under the new rules.
Frequently Asked Questions (FAQ)
Q: What happens if I don’t choose a cost basis method by January 1, 2026?
A: The IRS will default you to FIFO across all wallets—potentially increasing your tax bill. You’ll also lose Safe Harbor protection, increasing audit risk.
Q: Can I change my method after documenting it?
A: Not without IRS approval. Changing methods later may trigger penalties and disqualify you from Safe Harbor benefits.
Q: Does Safe Harbor apply to DeFi and NFTs?
A: Yes. All crypto assets are subject to these rules, including tokens from decentralized platforms and NFTs treated as collectibles.
Q: Do I need to report every wallet separately on my tax return?
A: Not necessarily—but you must calculate gains/losses per wallet or exchange. Aggregated reporting is allowed if consistent with your chosen method.
Q: Will exchanges provide compliant tax reports under the new rules?
A: Major exchanges are adapting, but many won’t support multi-wallet cost basis tracking yet. Relying solely on exchange data may lead to inaccuracies.
The Bottom Line: Act Now, Benefit Later
The 2025 crypto Safe Harbor provisions represent a rare opportunity to reset your tax foundation. By choosing the right allocation and accounting methods—and documenting them properly—you can reduce uncertainty, lower tax liabilities, and stay fully compliant.
This isn’t just about avoiding penalties; it’s about taking control of your financial narrative in the evolving digital economy.
