Keeping financial records and for how long
Retention periods vary by document, digital is generally acceptable, and the cost of not having something is asymmetric.

Financial paperwork accumulates until it is either thrown away too early or kept indefinitely, and neither is efficient.
Why it matters
The asymmetry.
Keeping a document costs almost nothing, particularly digitally.
Not having one when needed costs time, money and occasionally a great deal — a tax enquiry without records, an insurance claim without proof of purchase, a warranty claim without a receipt, a benefits claim without evidence of income.
Which argues for keeping more rather than less, organised well enough to find things.
Typical retention periods
Which vary by jurisdiction and follow a pattern.
Tax records: several years after the filing deadline for employees, and longer for self-employed people and businesses — commonly five to seven years, and longer in some systems.
Where a return was late or is under enquiry, the period extends.
Payslips: until checked against the annual summary, then the annual summary retained for the tax period.
Bank and card statements: typically a year or two for routine purposes, longer where they evidence tax-relevant transactions.
Investment records: until disposal plus the tax retention period, since acquisition costs are needed to calculate gains.
Property records: for as long as you own the property plus the retention period afterwards, including improvement costs which may affect tax on sale.
Insurance policies: for the policy period plus the period during which a claim could arise.
And receipts for anything under warranty or insured, for as long as that applies.
What to keep permanently
The short list.
Birth, marriage, civil partnership and death certificates.
Divorce and separation documents including financial orders.
Wills and powers of attorney.
Property deeds and mortgage documents.
Pension records, including scheme details and statements, since tracing lost pensions decades later is a common problem.
Records of contributions to state pension systems.
Educational and professional qualifications.
Life insurance policies.
And a record of any significant gift or loan within the family, which prevents disputes.
Digital records
Which are generally acceptable.
Tax authorities in most jurisdictions accept digital records, and several now require them for business.
Scan or photograph paper documents and store them systematically.
Back up in at least two places, one of them off-site or in cloud storage.
Use a consistent naming convention including dates, which is what makes retrieval possible.
Note that some documents — original deeds, certain certificates, share certificates — may need to exist in original form.
And ensure someone else can access them, which is the point that people miss until it matters.
A workable system
Simple enough to maintain.
One folder — physical or digital — per category: tax, property, pensions, insurance, banking, investments, employment, and personal documents.
One subfolder per tax year for anything year-specific.
A single index document listing what exists and where, including account numbers and providers.
A monthly ten-minute filing session rather than an annual excavation.
And an annual review to discard anything past its retention period.
The document nobody has
Worth creating.
A single summary listing every account, policy, pension, investment and debt, with provider, reference number and approximate value.
Plus digital accounts and how to access them, which is an increasingly significant gap in estates.
Plus key contacts: accountant, solicitor, financial adviser, employer.
Kept updated annually and stored where a trusted person can find it.
The absence of this document is the single largest practical problem faced by families dealing with a death or a sudden incapacity.
Disposing safely
Which matters for fraud.
Shred anything containing account numbers, addresses, dates of birth or signatures rather than putting it in recycling.
Securely delete digital files rather than only moving them to a bin folder.
Wipe devices properly before disposal, including phones and printers.
And be aware that discarded documents are a genuine source of identity theft.
Special situations
Where longer retention matters.
Anyone self-employed or with a business, where retention requirements are longer and enquiries can look back further.
Anyone with property, where acquisition and improvement costs matter on eventual sale.
Anyone with investments outside tax-advantaged wrappers, for the same reason.
Anyone who has been in an insolvency procedure.
Anyone with overseas income or assets, where reporting obligations are extensive.
And anyone who has made or received significant gifts, where inheritance tax rules in some jurisdictions look back years.
General information only, not financial, tax or legal advice. Retention requirements vary by country — consult a qualified accountant or your tax authority.
