# File your GSTR-1

This walkthrough details how to extract compliance data from GST Manager to prepare your statutory outward supplies return.

::: info Understanding GSTR-1
GSTR-1 is the mandatory return for outward supplies. GST Manager compiles all taxable transactions into standardized CSV files for direct reconciliation or upload.

## Step 1 — Check the filing deadline

## Step 2 — Configure the reporting period

Set the date parameters under **GST Manager → Reports**:

* Adjust the **From** and **To** date pickers to cover your target tax period (e.g. current month or quarter).
* Ensure date bounds align with your statutory filing frequency.

## Step 3 — Download the GSTR-1 CSV

1. Locate the **GSTR-1 (B2B & B2C)** report card.
2. Click **Download CSV**.
3. Inspect the exported file using the **Section** column:
   * **B2B rows:** Transactions with validated customer GSTINs. Map these records to Table 4A of your GSTR-1 return.
   * **B2C rows:** Transactions without a registered GSTIN. Map these records to Table 7 (B2C Others) of your GSTR-1 return.

## Step 4 — Export companion datasets

Download supplementary exports for comprehensive reconciliation:

* **Export invoices:** Filtered to international transactions (billing country outside India) for zero-rated export reporting in Table 6A.
* **Legacy — all paid invoices:** Complete ledger of domestic and international transactions for total revenue reconciliation.
