Section 145 of CGST Act 2017 — Admissibility of micro films, facsimile copies of documents and computer printouts as documents and as evidence

Section 145 of CGST explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

Section 145 of the CGST Act, 2017 provides that microfilms, facsimile copies of documents, statements contained in computer printouts and reproductions of images stored on any device shall be admissible as documents and as evidence in any GST proceeding, without producing the original, provided the conditions for their genuineness are satisfied.

What Section 145 Says — In Plain English

Modern business records rarely exist only on paper. Invoices live in accounting software, correspondence sits in email, and transaction data is backed up on servers and cloud storage. Section 145 modernises the rules of evidence so that electronic and photographic reproductions carry the same weight as paper originals. A microfilm, a fax copy, a computer printout, or a hard copy of electronically stored information can be produced in GST proceedings and treated as a document in its own right — the department does not have to produce the original.

This admissibility is not unconditional. For computer output, the party relying on it must show the computer was used regularly to store or process information of that kind, the data was fed in the ordinary course, the computer was operating properly, and the output accurately reproduces the stored information. These reliability conditions guard against tampered or unreliable printouts being passed off as genuine records.

Clause / Sub-section Breakdown

Applicability & Scope

Section 145 applies whenever the department relies on scanned invoices, emailed documents, backed-up accounting data, e-way bill records or server logs during adjudication, appeal or prosecution. It is especially important where originals are unavailable, voluminous, or held only on electronic systems — the printout or image can stand in for the original. It also covers digital records seized under Section 67 during search of computers, servers or cloud storage. The definition of "document" in Section 2(41), which includes electronic records, gives Section 145 its foundation.

The provision works both ways. It is not only a sword for the department; a taxpayer can equally rely on Section 145 to put in his own electronic records — for example ERP extracts, dispatch logs or bank statements — to rebut a demand, provided the same reliability conditions are met. This levels the evidentiary field in an economy where almost nothing is kept solely on paper. Scope also extends to reproductions at several removes: a microfilm of a document, a facsimile copy, a computer printout, and a hard copy of information stored on any device or media are each treated as a document in their own right, not as mere secondary evidence needing separate proof of the "best evidence" being unavailable. That said, admissibility is not the same as weight — once admitted, the reliability and completeness of the electronic record still influence how much the authority relies on it, so preserving unbroken audit trails, timestamps and system metadata materially strengthens whichever side produces the record.

Worked Examples

Example 1 — the fake-invoice laptop. Officers investigating a fake-invoice racket seize a laptop and take computer printouts of the accounting software showing invoices to non-existent buyers worth ₹2 crore. The originals were never printed and exist only in the software. Under Section 145, those printouts are admissible as documents and as evidence, provided the department shows the software was used regularly, data was fed in the ordinary course, and the printouts faithfully reproduce the stored data. The trader cannot object merely on the ground that no paper original exists.

Example 2 — the email trail. During inquiry, the department relies on a chain of emails (produced as printouts) negotiating an under-invoiced sale. Even without the "original" electronic message being displayed live, the printouts are admissible under Section 145 as reproductions of electronically stored information, once the reliability conditions are met — turning informal digital correspondence into usable evidence of the real consideration.

Step-by-Step in Practice

1. Identify the electronic or photographic record (printout, image, microfilm, fax copy). 2. Establish the reliability foundation for computer output — regular use, ordinary-course data entry, proper functioning, faithful reproduction (often via a certificate or officer's statement). 3. Tender the reproduction in the proceeding as a document under Section 145. 4. The record is admitted without production of the original. 5. Once admitted, it can also attract the Section 144 presumption of truth. 6. The opposing party may challenge the reliability foundation to resist admissibility.

Common Mistakes & Practical Notes

• Assuming a printout is worthless because there is "no original" — Section 145 treats it as a document in its own right.
• Overlooking the reliability conditions — computer output can be excluded if the foundation about regular, proper use is not laid.
• Deleting or altering system logs — this weakens a taxpayer's ability to challenge the department's printouts.
• Forgetting the link with Section 144 — an admitted printout can also enjoy the presumption of truth.
• Treating scanned copies casually — they are secondary reproductions and should be preserved with their metadata to defend authenticity.

Timelines & Related Sections

Section 145 has no independent time limit; it operates within whatever proceeding is running. It pairs with Section 144 (presumption as to documents) and supports search and seizure of electronic records under Section 67 and access to business records under Section 71. It underpins assessments and demands under Sections 73 and 74 that rely on digital data, and prosecutions under Section 132. The foundational definition of "document" is in Section 2(41).

The practical consequence for record-keeping is significant. Because electronic reproductions are admissible, the department can build a case entirely from data recovered off a seized server or cloud account, and a taxpayer can equally defend himself from his own backups — but only if those records survive intact. Deleted ledgers, overwritten logs or broken audit trails cut both ways: they weaken the taxpayer's ability to rebut a department printout and can themselves be treated as suspicious. Sound practice is therefore to retain the original electronic records for the statutory retention period (aligned with the record-keeping obligation under Section 35), preserve system-generated logs and metadata, and be able to demonstrate the reliability conditions — regular use, ordinary-course data entry, proper functioning and faithful reproduction — whenever electronic output is relied upon in a proceeding.

Recent Amendments & Context

Section 145 itself is stable, but the volume and importance of electronic evidence keeps rising. E-invoicing, e-way bills and the common portal now generate structured digital trails that flow straight into enforcement. The Finance Act, 2025's Section 148A track-and-trace mechanism, backed by the penalty in Section 122B, adds machine-readable markings whose linked data will typically be produced as computer output — precisely the kind of record Section 145 makes admissible. Taxpayers should therefore preserve original digital records, logs and metadata, since these both support and challenge such evidence. As enforcement leans ever more heavily on scanned invoices, e-way bill logs, IRP data and accounting extracts, Section 145 is quietly one of the most consequential procedural provisions in the Act: it is the bridge that lets the department, and the taxpayer, turn everyday electronic records into admissible evidence without hunting for a paper original that may never have existed.
