Where's the proof?
Meet KarSafe.
Over 9 crore Indians filed ITRs in FY 2024-25. Every one of them needs to preserve income proofs for years. Almost none of them do it properly.
Form 16 in email. Rent receipts on WhatsApp. Salary slips on a phone you traded in. No single place holds it all.
You change laptops every 3-5 years. The drive from 2020 is gone, and 42% of data loss is hardware failure. Proofs rarely survive the move.
Foreign proofs sit across countries and former employers, and the Black Money Act sets no time limit. Return to India and every foreign bank statement, ESOP exercise, and DTAA claim must be accounted for. Most can't find last year's, let alone 2015's.
A folder of 47 unsorted files won't help when the IT department asks for one proof from 3 years ago. You need it searchable, not just stored.
No documents, no deduction. Honest claims become "discrepancies": a Rs 25,000 penalty under Section 271A, plus the disallowed tax, plus interest.
The notice arrives and you can't find the proof. The sleepless nights and frantic searching are a real, avoidable toll.
KarSafe exists because filing taxes is only half the job. The other half is preserving the proof — encrypted, organized by year, searchable, and accessible for as long as the law demands.
KarSafe is designed for the way real people handle tax documents. Upload from anywhere. Find anything instantly. Export with a professional annexure.
Scan, pick a file, or share from email or WhatsApp. Auto-tagged by year and type.
Search every year by type, source, or keyword. No more digging through folders.
One encrypted ZIP with a table-of-contents PDF, ready for your CA or an IT notice.
KarSafe isn't just cloud storage. It's a purpose-built vault designed for Indian income and tax document compliance.
Documents are encrypted on your device with quantum-resistant AES-256 before upload. We never see your cleartext files. Not even we can read them.
Every document tagged by Assessment Year or Tax Year. Automatically sorted. Find Form 16 from 3 years ago in seconds, not hours.
Each document is encrypted with its own unique key. Even if one key were compromised, no other document is affected.
Download all your documents as encrypted or decrypted ZIP archives. Your data is always accessible to you — no lock-in.
Find any income proof across all years instantly. Filter by document type, income source, or year. No more digging through folders.
Full compliance with India's Digital Personal Data Protection Act. Explicit consent, right to erasure, data portability, and grievance redressal.
Most taxpayers don't realise how long they must preserve income documents. A demand from the IT department can come years after filing.
Keep records supporting your ITR for at least 6 years. Recent years can be reopened for about 5 years; returns filed before late 2024 can still be reopened under the earlier, longer rules — so don't discard them early. Covers Form 16, salary slips, rent receipts, and investment proofs.
The Black Money Act sets no time limit — foreign income and assets can be reopened at any time, so keep these records permanently. NRIs and returning Indians must preserve Schedule FA filings, ESOP/RSU exercise statements, foreign bank records, and DTAA relief proofs — across jurisdictions and former employers.
For businesses with international transactions, transfer pricing documentation must be kept for 8 years. Cross-border invoices, agreements, and benchmarking studies.
For capital gains on property, you need the original purchase deed, payment proofs, and improvement costs — often from decades ago. There's no practical expiry on these records.
