Could Your 1099-DA Trigger an IRS Review?

Most IRS notices are generated through automated data matching.

Form 1099-DA introduces a new reporting layer into that system.

How Matching Works

When an exchange issues a 1099-DA, a copy is sent to the IRS.

The IRS system compares:

- Proceeds reported on the 1099-DA against

- Gains and income reported on your return

If the discrepancy exceeds tolerance thresholds, the return may be flagged.

This initial review is automated.

Why Crypto Is Structurally Different

Traditional brokerages maintain internal cost basis records.

Crypto ecosystems span:

- Wallets

- Exchanges

- DeFi protocols

- Bridges

- Staking systems

Without full reconstruction of acquisition history, mismatches become more likely.

What Creates Audit Risk

- Large divergence between reported proceeds and gains

- Missing cost basis

- Inconsistent transaction logic

- Unexplained reporting discrepancies

The risk is structural.

The Audit-Defensible Approach

DeFi Tax reconciles centralized and decentralized activity using blockchain data.

The result:

- Deterministic cost basis calculations

- Reproducible reporting

- Alignment between 1099-DA proceeds and filed return

Audit-ready means your figures can be explained, not just formatted.

Bottom Line

1099-DA marks a formal shift in digital asset reporting.

If you traded crypto, do not assume exchange data reflects the full picture.

Ensure your return reflects your complete transaction history.

Accuracy is now the standard.
