Cryptocurrency tax reporting is a complex process, and one of the primary challenges is selecting the right cost tracking method. For crypto investors in the US, the IRS has recently updated its guidance on cost basis tracking, which can significantly impact how you report your taxes. In this post, we'll explore two popular methods— Universal vs Wallet-Based Cost Tracking —and help you determine which approach best suits your tax situation. We'll also provide a practical guide with examples to help clarify the process.
What Is Cost Basis Tracking in Crypto?
Cost basis tracking is the process of determining the original value of your crypto assets, including the purchase price, fees, and any other associated costs. This information is crucial for calculating your capital gains or losses when you sell, trade, or use cryptocurrencies. Choosing an appropriate tracking method can have a major effect on the taxes you owe.
Universal vs Wallet-Based Cost Tracking Explained
The two main approaches to tracking your cost basis are the universal method and the wallet-based method. Let's break down the differences:
Universal Cost Tracking
In a universal cost tracking method, all of your cryptocurrency transactions across all wallets and exchanges are treated as part of one unified pool. This means that, regardless of where you bought, sold, or transferred your crypto, each transaction is considered as if it originated from a single inventory.
Advantages:
- Simplification: By treating all your holdings as a single pool, record-keeping becomes simpler, especially for individuals using multiple exchanges and wallets.
- Flexibility in Tax Lot Identification: The universal method allows you to choose specific tax lots to minimize capital gains, such as using Highest-In-First-Out (HIFO) or Last-In-First-Out (LIFO) strategies.
Drawbacks:
- Complexity with Transfers: If you frequently move assets between wallets or exchanges, tracking the entire pool accurately for tax purposes can become challenging.
Wallet-Based Cost Tracking
Wallet-based cost tracking keeps each wallet and exchange account separate, meaning you track the cost basis of assets within the specific wallet or exchange where they are held.
Advantages:
- More Accurate Tracking: Wallet-based tracking provides a more granular view of your transactions, which can be beneficial if you use specific wallets for distinct purposes.
- Compliance Benefits: Wallet-based tracking is more aligned with how exchanges report transactions to the IRS, especially given recent IRS guidance on crypto reporting.
Drawbacks:
- Increased Complexity: Tracking the cost basis separately for each wallet or exchange can become cumbersome, particularly for active traders.
- Limited Lot Selection Flexibility: With wallet-based tracking, your ability to choose tax lots is more limited, as you can only select from the transactions within a specific wallet.
Recent IRS Developments
The IRS recently issued new guidance that affects how cost basis should be reported for crypto assets. Specifically, the IRS emphasizes the importance of consistent cost basis reporting, meaning taxpayers must clearly indicate which method— Universal vs Wallet-Based Cost Tracking —they are using and stick with it throughout the tax year. Additionally, starting from January 1, 2025, wallet-based cost tracking will become compulsory for all crypto investors in the US. This means that each wallet or exchange must have its own separately tracked cost basis, and investors will no longer be able to pool their assets across multiple wallets and exchanges for tax purposes.
Furthermore, the IRS has introduced changes regarding broker reporting obligations, which include exchanges reporting user transaction data directly to the IRS. This development makes wallet-based tracking more favorable for some users, as it aligns better with how exchanges are required to report their data.
Allocation of Unused Tax Lots from January 1, 2025
With the new wallet-based tracking requirement, any unused tax lots will need to be allocated specifically within each wallet or exchange. This means that if you have assets held in multiple wallets, you must manage each set of tax lots independently. For example, if you use a First-In-First-Out (FIFO) method, you will need to apply it separately to each wallet or exchange rather than across your entire portfolio.
This change has practical implications for tax optimization. Investors will have less flexibility in selecting tax lots from different wallets to minimize gains. Instead, the focus will shift to optimizing transactions within each individual wallet. This makes detailed record-keeping and careful transaction planning even more important.
Practical Guide: How to Choose the Right Method
Example 1: The Active Trader
Imagine you're an active crypto trader who frequently buys and sells assets across several exchanges like Coinbase, Binance, and Kraken. You also use multiple wallets—a hot wallet for day-to-day transactions and a cold wallet for long-term storage.
In this scenario, a universal cost tracking approach may have previously simplified your reporting and allowed for better tax optimization since it enabled you to pool all your holdings and treat them as a single inventory. However, with wallet-based tracking becoming compulsory from January 1, 2025, you will need to manage each wallet separately, which could increase complexity but align better with the IRS's new reporting requirements.
Example 2: The HODLer
Consider a different type of investor: someone who has held Bitcoin and Ethereum for years in a hardware wallet, only occasionally moving coins to a hot wallet for trading or spending.
For this investor, wallet-based tracking is already a suitable choice. Since movements between wallets are minimal and each wallet serves a specific purpose, keeping cost basis records separately will align well with the new IRS requirements and provide greater accuracy.
Tips for Practical Implementation
- Choose One Method and Stick with It Until 2025: Until January 1, 2025, you may still use either Universal vs Wallet-Based Cost Tracking, but be prepared to transition to wallet-based tracking by the deadline.
- Use Tools for Automation: Consider using tax software that supports wallet-based tracking. Tools like CoinTracking, Koinly, or professionals like CountDeFi can help automate the calculations, making the process more manageable.
- Be Ready for IRS Reporting: Whether you use Universal vs Wallet-Based Cost Tracking method, make sure to keep detailed records of each transaction, including transfers between wallets, as the IRS is increasingly scrutinizing crypto transactions. After January 1, 2025, ensure that you maintain separate cost basis records for each wallet or exchange.
Conclusion: Universal vs Wallet-Based Cost Tracking—Which Is Right for You?
Choosing between Universal vs Wallet-Based Cost Tracking depends on your crypto activity, trading frequency, and comfort with complexity. However, with the recent IRS guidance, wallet-based tracking will become mandatory from January 1, 2025. If you value simplicity and flexibility in tax optimization, you may prefer universal tracking until the deadline, but be prepared for the shift to wallet-based tracking.
Staying informed of IRS developments and maintaining accurate records is crucial for compliance. With the IRS intensifying its focus on crypto transactions, it's more important than ever to use a cost tracking strategy that fits your individual needs and aligns with regulatory changes.

Frequently Asked Questions
What is cost basis tracking?
It is working out the original value of your crypto, including the purchase price, fees and other associated costs. That figure is what your capital gain or loss is measured against when you sell, trade or spend the asset.
What is the difference between universal and wallet-based tracking?
Universal tracking treats every transaction across all wallets and exchanges as one unified pool, as if each disposal came from a single inventory. Wallet-based tracking keeps each wallet and exchange account separate, so basis is tracked within the specific account where the assets are held.
Which method does the IRS require?
From January 1, 2025 wallet-based tracking became compulsory for crypto investors in the US, so each wallet or exchange needs its own separately tracked cost basis and assets can no longer be pooled across accounts. The IRS also expects consistent reporting, meaning you indicate which method you are using and stay with it through the tax year.
What happens to unused tax lots under the new requirement?
Unused tax lots have to be allocated within each wallet or exchange and managed independently. If you use first-in first-out, for example, it applies separately to each account rather than across the whole portfolio.
Does wallet-based tracking reduce my tax planning options?
It narrows them. Lot selection is limited to the transactions inside a specific wallet, so the focus shifts to optimising within each account rather than choosing lots across the portfolio. That makes detailed records and transaction planning more important.
Which method suited an active trader compared with a long-term holder?
An active trader across several exchanges and wallets previously gained the most from pooling, and now has to manage each account separately. A long-term holder who keeps coins in a hardware wallet and moves them rarely was already close to wallet-based tracking, so the change is a smaller adjustment.
