Cash App Bitcoin Taxes 2026 – Complete Reporting Guide

Millions of Americans buy Bitcoin through Cash App. If you sold Bitcoin on Cash App in 2025, you likely received a 1099-DA – here is what to do with it.

Does Cash App Report to the IRS?

Yes. Cash App (operated by Block, Inc.) reports cryptocurrency transactions to the IRS. For tax year 2025 (filed in 2026), Cash App issues Form 1099-DA to users who sold crypto, and sends a copy to the IRS.

The 1099-DA reports: gross proceeds from crypto sales. It may or may not include your cost basis, depending on Cash App's reporting systems.

Where to Find Your Cash App Tax Forms

1. Open Cash App → Profile icon → Documents
2. Select "Tax Documents"
3. Download your 1099-DA (available by January 31)

Cash App also provides a transaction history CSV you can export for more detail.

The Cost Basis Problem

A key issue with Cash App: many users bought Bitcoin years ago when cost basis tracking was minimal. If Cash App cannot determine your cost basis, the 1099-DA may show $0 or "unknown" as your basis – making your entire proceeds look like gain.

Solution: Gather your purchase records. Check your Cash App transaction history, bank statements, and email confirmations. Even estimates are better than letting the IRS assume $0 basis.

How to Calculate Your Gain/Loss

Capital Gain = Proceeds (from 1099-DA) − Cost Basis (what you paid for the Bitcoin)

If you made multiple purchases, use FIFO (first in, first out) by default, or choose Specific Identification if you can document it.

Filing Your Cash App Bitcoin Taxes

1. Export your full transaction history from Cash App
2. Import into crypto tax software (CoinTaxReporting, Koinly, etc.)
3. Verify the calculated gains match your 1099-DA proceeds
4. Transfer data to Form 8949
5. Report totals on Schedule D

What If You Only Bought, Never Sold?

If you only purchased Bitcoin through Cash App and never sold, exchanged, or spent it, you have no taxable event and no tax to pay (yet). You only owe taxes when you dispose of crypto.

Bitcoin Used for Payments via Cash App

If you used the Cash App "Pay" feature or sent Bitcoin to others as payment, each transaction is a taxable disposal – just like selling. The fair market value on the date of transfer determines your proceeds.
