Honest taxpayers are the most vulnerable

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.

Scattered across devices

Form 16 in email. Rent receipts on WhatsApp. Investment proofs in a folder you renamed twice. Salary slips on an old phone you traded in. No single place holds everything.

💻

Laptops fail. Phones get replaced.

You replace your laptop every 3-5 years. That hard drive from 2020? Gone. 42% of all data loss comes from hardware failure. Your income proofs don't survive device transitions.

🔍

Even if you have it, can you find it?

A folder called "Tax Stuff 2022" with 47 unsorted files doesn't help when the IT department asks for a specific investment proof from 3 years ago. You need it searchable, not just stored.

The real cost of missing proofs

Without documents, legitimate deductions get disallowed. Honest claims become "discrepancies". Penalty of Rs 10,000 per instance of failure to produce documents — plus the disallowed tax itself, plus interest.

😤

The stress no one talks about

An IT notice arrives and you can't find the proof. The sleepless nights, the anxiety, the frantic searching — the emotional toll of not having your documents in order is real and significant.

🌎

NRIs have it worse

Foreign income proofs scattered across countries and former employers. Schedule FA demands 16 years of records under the Black Money Act. Returning to India? Every foreign bank statement, ESOP exercise, and DTAA claim must be accounted for — and most people can't find last year's, let alone 2015's.

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.

The law requires you to retain income proofs

Most taxpayers don't realise how long they must preserve income documents. A demand from the IT department can come years after filing.

7 yrs

Standard Income Records

Under the Income Tax Act, all records supporting your ITR must be preserved for 7 years from the end of the relevant assessment year. This includes Form 16, salary slips, rent receipts, and investment proofs.

16 yrs

Foreign Income & Assets

The Black Money Act requires retention of records for 16 years. 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.

10 yrs

Transfer Pricing (Business)

For businesses with international transactions, transfer pricing documentation must be maintained for at least 10 years. Cross-border invoices, agreements, and benchmarking studies.

Property & Capital Gains

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.
