Difference between IFF and GSTR-1

What is IFF?

The Invoice Furnishing Facility (IFF) is a facility where quarterly GSTR-1 filers can Upload  their Business-to-business (B2B) invoices in their IFF Return.

Difference between GSTR-1 And IFF?

GSTR-1 is a Sales Return through which tax payers have to upload their B2B and B2C invoices.

Basic difference between these 2 is that B2C invoices cannot be upload in IFF.

Like in January and February we have B2B invoices and we wish to upload those invoices in IFF as we want our customers to claim their Input Tax Credit on the basis of Gstr-2B.

Then we will have to upload B2B invoices for March and  remaining B2C invoices of (Jan,Feb,March) in March Gstr-1(Quarterly).

IFF Facility is optional while GSTR-1 is compulsory.

IFF cannot be file after its cut off date.
