# Filing GSTR-6: GSTR-6A Reconciliation

## Invoice Matching - GSTR-6A Reconciliation

Use GSTR-6A reconciliation to compare the ISD purchase register uploaded in Octa with the GSTR-6A data fetched from the
GST portal.

To start reconciliation:

1. Go to **GSTR-6A Reconciliation**.
2. Select the period you want to reconcile.
3. Review the purchase and GSTR-6A document counts shown on the dashboard.
4. Click **Match and Reconcile**.

Octa will match the records and update the reconciliation results.

In the dashboard:

- **Orange** represents purchase register documents.
- **Purple** represents GSTR-6A documents.

In the reconciliation view:

- Fields matching perfectly are shown in **green**
- Fields almost matching are shown in **light green**
- Fields not matching are shown in **red**
- **Orange** indicates purchase documents that remain unmatched
- **Purple** indicates GSTR-6A documents that could not be reconciled with your purchase register

## Reconciliation Statuses

### Match

A **Match** means the purchase document is fully aligned with the corresponding GSTR-6A entry. Key details such as
invoice number, invoice date, taxable value, and tax amount match between the purchase register and GSTR-6A.

### Almost Match

An **Almost Match** means Octa found a probable match, but some values are slightly different. This may happen because
of rounding differences, small date or invoice number variations, or formatting differences.

Review almost matched records before claiming ITC.

### Mismatch

A **Mismatch** means the purchase document and GSTR-6A entry are linked or compared, but important values do not match.
Review the differences and correct the source data if required.

### Missing in GSTR-6A

**Missing in GSTR-6A** means the invoice is available in the purchase register but not in GSTR-6A. These records are
shown in **orange**.

This usually means the invoice is recorded in your books but is not available in the government portal data for the
selected period.

### Missing in Purchase Register

**Missing in Purchase Register** means the invoice is available in GSTR-6A but not in the purchase register. These
records are shown in **purple**.

This usually means the invoice is available on the portal but has not been recorded or imported in the ISD purchase
register.
