A good proof
- Is the actual document (the challan, the certificate, the signed register), not a screenshot of a summary.
- Names the period and the entity it is about.
- Is uploaded when the work is done, by the person who did it.
Why it cannot be edited
An uploaded file is stored by its content hash. Replacing it creates a new version; the old one stays. That is what lets you show an auditor what you knew and when.
Who checks
The maker submits, a different person reviews. If you are the maker you cannot approve your own work, however senior you are.
Small habits
- Name files by what and when: "PF-challan-2026-08.pdf".
- Add the note that explains a late filing at the time, not months later.
This is working guidance for your team, not legal advice. Confirm the details against the current text of the law and your State's rules before you rely on them.
Frequently asked questions
Can I delete a wrong upload?
No. Upload the correct file as a new version and say why in the note. The history is the point.
What if a file is large?
Files up to 25 MB can be attached here. For anything larger, keep it in your document store and attach a summary that names where it is.
