# HR Systems

> Connect your HR system to Numeral to automatically track physical nexus and stay compliant with state sales tax requirements.

If your company has employees, offices, or warehouses across the US, you may have **physical nexus** in those locations—and could be required to collect and remit sales tax. As your business grows, tracking these obligations can become complex.

<Note>
  Numeral uses [Finch](https://www.tryfinch.com/for-employers?utm_source=finch_connect\&utm_medium=product\&utm_campaign=for_employers), a secure platform with end-to-end encryption, to connect your payroll and HR systems to Numeral. Your credentials are never shared with our team.
</Note>

Once connected, Numeral automatically detects when new employees or physical locations create nexus obligations and notifies you so you can stay compliant.

## Connect Your HR System

1. **Go to your Numeral dashboard.**

2. **Click Connections** in the left-hand menu, then select **Add Connection** in the top-right corner.

3. **Scroll to the "Human Resources" section**, then choose your HR system (e.g., Rippling, ADP, BambooHR).

4. **Accept Finch Terms & Conditions.** Finch enables a secure integration between Numeral and your HR system.

5. **Authorize the connection.** Your HR system will open in a new window.

   <Warning>
     You must have **admin access** to authorize Finch as a third-party app.
   </Warning>

6. **Confirm the connection.** Once authorized, you'll return to Numeral. A **green dot next to "Syncing"** confirms the connection is live.

## How it Works

Once connected, your **physical nexus data** is tracked in Numeral under **Settings > Physical Presence**. Nexus information is automatically updated based on changes in your HR system, keeping your compliance current without any manual effort.

When you add employees or open new locations in a state where you're not currently filing sales tax, Numeral will **notify you to register** in that jurisdiction.

<Tip>
  Review your **Physical Presence settings** on a regular basis to ensure all new locations and employees are being tracked correctly.
