How long to keep documents (and which to scan before tossing)

Paper clutter is mostly retention anxiety: “what if I need it?” Scanning dissolves the dilemma — keep the information forever at zero shelf space, keep the paper only as long as rules require.

Rules of thumb (verify locally)

Document	Paper	Scan
Everyday receipts	Until return window ends	Scan if warranty/tax-relevant, else skip
Warranty receipts	Warranty period	Keep scan for the product's life
Tax records	3–10 years per jurisdiction	Keep scans indefinitely — negligible cost
Contracts/leases	Term + limitation period	Indefinitely
Payslips/statements	Until reconciled/replaced by annual docs	A few years' scans is plenty
IDs, vital records, deeds, diplomas	Forever — originals irreplaceable	Scan as backup, never as replacement

The scan-then-toss workflow

1. Monthly, triage the paper pile into: legal-original (keep paper), reference (scan → toss), noise (toss).
2. Scan the reference pile in one ToPDF batch session; file per the naming scheme.
3. Shred anything tossed that carries personal data — bins are public archives.

Why scans changed the math

Retention rules were written for filing cabinets, where keeping had a cost. A scanned archive costs nothing to keep and seconds to search — so the modern rule is simple: when in doubt, scan it, then apply the paper rule to the paper. Fading receipts especially: the scan will outlive the thermal print by decades.

Frequently asked questions

Are scans legally as good as originals?

For evidence and reference, digital copies are widely accepted; certain instruments (notarised deeds, some originals-required processes) still demand paper. That’s why the table keeps “irreplaceable originals” forever.

Should I scan things before storing paper long-term too?

Yes — paper degrades and gets lost in moves; the scan is the insurance policy for the original, not just its replacement.
