Business record retention in Singapore. Record-Retention Guide

If you run a small business or manage an office in Singapore, you’ve probably asked: How long do I actually need to keep these documents?

The answer matters — not just for compliance, but for freeing up physical space. Many offices keep files that are no longer legally required, clogging file cabinets and storage rooms.

Singapore has two main regulatory frameworks you need to know: IRAS (for financial and tax records) and MOP (for employment records). Together, they tell you what to keep, for how long, and what you can safely dispose of.

Let’s walk through the rules, and then show you a practical approach to organizing and storing them.

IRAS Record Retention: 5 Years from the Year of Assessment

The Inland Revenue Authority of Singapore (IRAS) requires companies to retain proper business records and accounts for at least five years from the relevant Year of Assessment.

What counts as “proper business records”? IRAS is looking for:

• Invoices and receipts — all sales and purchase documentation
• Bank statements and payment records — proof of income and expenses
• Payroll records — if you have employees
• General ledger and accounting journals — your financial transaction trail
• Tax returns and supporting schedules — copies of what you filed
• Contracts and agreements — vendor, client, and lease documents

Example: If you filed your 2025 tax return in mid-2026 (Year of Assessment 2025), you must keep those supporting documents until at least June 2031.

The five-year clock runs from the “relevant Year of Assessment” — typically the year in which you earned the income or incurred the expense, not the year you filed your return. So if you’re unsure which year a document belongs to, err on the side of keeping it.

What you can destroy after five years: Once the retention period expires and you’re confident IRAS won’t audit that year, you can safely dispose of the supporting documents. Your filed tax return itself is often useful to keep permanently for business reference, but the invoices, receipts, and bank statements can go.

MOP Employment Records: 2 Years for Current Employees, 1 Year After Departure

The Ministry of Manpower (MOP) has separate rules for employment records. These cover:

• Payroll records — wages, deductions, benefits paid
• Attendance and leave records — working hours, absences, approved leave
• Performance reviews and disciplinary records — formal evaluations and warning letters
• Medical and safety records — workplace health documentation

For current employees: Keep the latest two years of employment records.

For former employees: Keep their final two years of records for one year after they leave. After that one-year grace period, you can dispose of them.

Example: If an employee resigned on 1 July 2025, you must keep their last two years of records (from July 2023 onward) until 1 July 2026. After that date, you can archive or shred them.

This applies to employees covered under the Employment Act — typically full-time and many part-time staff. If you have contractors or foreign domestic workers, different rules may apply; consult MOP’s website or a HR advisor if you’re unsure.

Organizing Your Business Records by Retention Period

Now that you know the timelines, how do you actually manage it? Most small businesses use a simple file organization approach:

Year 1–2 (Active records):

• Store in your office or easily accessible filing cabinets
• These are your “in-use” records for day-to-day reference
• Both IRAS and MOP rules apply — keep everything

Year 3–5 (Archive — IRAS retention window):

• Move tax and financial records to a secondary location or archive box
• Keep employment records for current staff; file former-employee records by departure date
• You likely won’t need these often, but they’re legally required

Year 5+ (Post-IRAS window):

• Tax and financial records can be disposed of (shred or certified destruction)
• Employment records for former staff can be disposed of (one year after departure)
• Current-staff records still in the 2-year window move to storage

Organizing tip: Label every box or file with the year and content type (“2025 Invoices”, “2024 Payroll Records”, etc.). This makes it easy to know when it’s safe to dispose of each batch.

The Space Problem: Why Off-Site Storage Makes Sense

For growing businesses, this becomes a real problem. A year’s worth of invoices, receipts, and payroll documents can fill 20–30 archive cartons, depending on your transaction volume. By year three, you might need a full filing cabinet just for archive records.

Many offices solve this by keeping only the current two years on-site, then moving older records to off-site document storage. This frees up valuable office space while keeping records retrievable if you ever need them (or if IRAS has questions).

The advantage is flexibility: if IRAS audits your 2021 tax year, you can request retrieval of those specific cartons within 24–48 hours. You’re not scrambling through an overflowing storage room or paying emergency courier fees.

Off-site storage also protects your records. Archived boxes are kept in a secure facility, away from office water damage, fire risk, or accidental disposal.

Compliance Responsibility

It’s important to note: you remain responsible for determining which records to retain and for how long. IRAS and MOP set minimum requirements, but your business may have additional retention obligations — for example, if you work in regulated industries like finance or healthcare, or if you have specific contractual or lease obligations.

If you’re unsure whether a particular record type falls under IRAS or MOP rules, consult your accountant or HR advisor.

Getting It Done

To organize your current archive:

1. Gather all tax and financial records from the past five years
2. Gather all employment records (current employees’ last two years; former employees by departure date)
3. Separate into boxes by year and category
4. Label clearly with dates and contents
5. Dispose of anything outside your retention windows

To stay on top of it going forward:

• Schedule a quarterly 15-minute review of what’s reached its retention limit
• Shred or certify destruction rather than just discarding — many businesses use a certified document destruction service
• Move records older than 2 years to archive storage to keep your office lean

Off-Site Document Storage for Growing Businesses

If you store 20+ cartons regularly or don’t have space for archive records on-site, off-site document storage can be a practical solution. You can retrieve specific cartons on request, and your records stay organized and accessible — no hunting through boxes in a back storeroom.

Businesses across Singapore — from accounting firms to retail chains to corporate offices — use this approach to balance compliance, space, and convenience.

The bottom line: Singapore’s record-retention rules are straightforward once you know the timelines. IRAS wants five years of tax and financial records; MOP wants two years of employment records for current staff, one year for former staff. After that, you can dispose of them safely.
