About BasisBridge

BasisBridge is the done-for-you Form 1099-DA reconciliation service — we rebuild the cost basis your broker left blank, tie every sale to its evidence, and hand you (or your CPA) a Form 8949-ready pack. Records reconciliation only — never tax advice, never filing.

2025 forms reported proceeds only

Form 1099-DA reporting began with 2025 transactions, when brokers reported gross proceeds only — cost basis was left to the holder.

2026 basis covers covered lots only

For 2026, basis appears only for covered lots — everything bought earlier or transferred in stays noncovered, basis blank.

Transferred-in coins arrive basis-blind

Transferred-in coins arrive basis-blind at every broker — permanently.

The IRS matches the proceeds figure

The IRS matches the proceeds figure it received. An unreconciled return is a notice waiting to happen.

BasisBridge reconciles every disposal on your 1099-DA against your purchase records — FIFO lot matching, transfer-in tracing, a missing-basis exception list with the evidence for each fix — and delivers a Form 8949-ready workbook your CPA can file from. Flat price. No API keys to hand over. No software to learn.
