Received a 1099-DA from Coinbase? Beware of Incomplete Data

A lot of people are confused after receiving their Coinbase 1099-DA forms. Many report that their figures seem off. Are they wrong, or just incomplete? For transactions in 2025, filed this year, the cost basis isn’t always reported fully. This can lead to issues when filing taxes.
What You Need to Know About Your 1099-DA
The 1099-DA typically reflects only gross proceeds from sales, meaning actual gains or losses may not be indicated. Relying solely on this document can cause some critical mistakes:
Overpaying on taxes due to miscalculations.
Underreporting gains, leading to potential penalties.
Filing inconsistent information between tax documents.
This document only captures transactions from Coinbase, but remember: crypto activities often spread across various platforms. Transfers to wallets, decentralized finance (DeFi), and staking are not reconciled just by looking at the 1099. Your tax obligations are tied to your entire transaction history.
“I wish I could download the form I paid for. Only waiting on Koinly so we can file,” laments one user on a forum.
First-Timer? Here’s Your Game Plan
For those filing crypto taxes for the first time, the process can be disorienting. Follow these steps:
Create an account with tax reporting software.
Connect your exchanges and wallets.
Allow the software to reconcile your transactions.
If you have filed taxes before, be aware that the ecosystem is shifting with new reporting standards. Stay updated and review each transaction carefully. The calculations matter more than the form itself.
Using Koinly for Easier Filing
To ease the tax filing process, Coinbase has teamed up with Koinly. You can now access Koinly via the Coinbase US Tax Center, receiving exclusive discounts for Coinbase and Coinbase One users. Discounts apply automatically at checkout.
Koinly offers a smooth solution to reconcile your complete crypto history across all platforms and creates Form 8949 and Schedule D based on accurate data. Here are some highlights:
Free reconciliation for up to 10,000 transactions.
Pay only if you need to download reports.
If you dislike the reconciliation before downloading, you can get a refund.
“So we don’t need to send this form as long as we sync through Koinly, correct?” asks another user, highlighting the confusion around documentation.
Key Insights
➡️ Many users see discrepancies in reported amounts.
⬅️ CoinTracker was mentioned, but Koinly offers a more comprehensive service.
🔻 The tax season is set to be chaotic, but users can simplify filing through new tools organized for them.
In these times of shifting requirements and evolving tools, confusion in tax documentation is expected. However, ensuring that every transaction is accurately represented can make all the difference when tax day arrives.
What Lies Ahead for Crypto Tax Filers
There’s a strong chance that the IRS will increase scrutiny on crypto transactions in the coming years as the market matures and regulations become clearer. Experts estimate that this could result in a significant rise in penalties for those who fail to report accurately, with some predicting penalties could increase by approximately 30% by 2027. Additionally, as taxpayers adapt to new software solutions like Koinly, the likelihood of more comprehensive and accurate reporting rises. Still, many people might face initial hurdles as they familiarize themselves with these systems, leading to a mixed bag of outcomes in this tax season.
A Surprising Echo from History
Consider the dot-com boom of the late 90s—startups flourished while investors experienced a steep learning curve in tech-based valuations. Just as many entrepreneurs learned the importance of accurate accounting and disclosure during that period, today’s crypto investors are similarly navigating uncharted waters. The chaos of that era led to clearer rules and more structured regulations, a lesson in resilience that crypto enthusiasts might also have to embrace. Just as tech startups refined their practices through trial and error, crypto tax filers will need to adapt to ensure that their financial futures remain secure.
