How long to keep documents — and which ones to scan
Published September 26, 2026
Most household paper falls into three piles: keep forever, keep for a while, and safe to discard once digitized. Knowing which pile a document belongs to is what makes decluttering safe. The periods below are common, conservative rules of thumb — retention rules differ by country and situation, so treat this as a starting framework and check locally for anything tax- or legal-critical.
Keep the original, forever
Some documents matter as physical originals because institutions may demand the original: birth and marriage certificates, diplomas and degree certificates, notarized deeds, wills, and court judgments. Scan them anyway — the scan is your everyday working copy and your disaster backup — but never discard the paper. Store the originals flat, dry and together; the scan means you will rarely need to touch them.
Keep for years: tax, contracts, insurance
Tax-related records are commonly kept for around five years after filing, matching typical audit windows. Contracts deserve keeping for the life of the agreement plus a few years — disputes tend to surface late. Insurance policies: keep while active plus the claim period. Pay slips and employment contracts: keep at least until pension and severance calculations are beyond doubt. For all of these, a good scan is usually an acceptable working record, with paper as backup for the highest-stakes items.
Scan and shred: the short-lived pile
Utility bills, card statements and delivery slips age out fast — a year covers most disputes. Receipts for everyday purchases matter only until the return window closes, unless they support a warranty or a tax deduction. Product manuals are all online. This pile is where scanning shines: digitize in batches, name files by date, and shred the paper. Anything with your name, address or account fragments should be shredded, not binned whole.
A simple system that survives real life
Three digital folders mirror the three piles: Permanent, Active (with subfolders per year), and an inbox for this month’s scans that you sort once a month. Scan new paper at the moment it enters the house. Once a year, delete the Active year that has aged out. The system works because it has exactly one decision per document — which pile — and everything else is routine.
