Short answer

How can I audit my nexus and transaction history with AI?

Your AI client pulls your current nexus locations and specific order data directly from TaxJar. You'll get a clear view of where you have tax obligations and the exact transactions that triggered them.

Where your data lands.

Audit outcomes

The AI organizes your tax data into these specific areas.

LOCATIONS

Nexus footprint

The AI identifies every state or region where you have established nexus. You'll see exactly where you're liable for sales tax.

ORDERS

Transaction lists

Your agent pulls specific order records to match against your sales. This helps you verify that every taxable event is accounted for.

RECONCILIATION

Discrepancy reports

The AI compares your nexus list against your order history. It flags orders that fall into new or unmonitored tax jurisdictions.

HUMAN

Final filing decisions

The AI provides the raw data and the logic, but you make the final call on filing and tax adjustments. It won't submit returns for you.

The workflow

What your AI does when the request arrives.

The AI acts as a bridge between your chat interface and your TaxJar account.

  1. Map your footprint

    The AI scans your account to find all active tax jurisdictions where you have a presence.

  2. Pull sales data

  3. Inspect specific orders

    When you need to dig deeper into a single sale, the AI pulls the full details for that specific transaction.

  4. Analyze for compliance

    The AI looks for patterns between your nexus locations and your order history to find gaps.
