Step 3 · The chart of accounts (where money lands) ​

In one sentence ​

An "account" is a drawer in the ledger. Every entry you make picks a drawer — picking the wrong one throws no error, but your reports and tax filing will be wrong.

1. You only need four categories ​

TypeWhat it meansExamples
AssetThings the company ownsBank balance, computers, renovation
LiabilityMoney the company owesSuppliers, the director's advances, CPF
RevenueMoney coming inTuition, corporate training
ExpenseMoney spent and goneRent, utilities, stationery

2. 🔴 The big one: buying something is not always an "expense" ​

This is the most common beginner mistake and the hardest to unwind.

The test is one sentence: if it lasts more than a year and wasn't cheap, it's an asset, not an expense.

What you boughtGoes toWhy
A ream of A4 paper, $125810 Stationery → expenseConsumed
A laptop, $1,8991410 Computers & IT → assetLasts years
A classroom TV, $1,2001430 Office equipment → assetSame
Renovation, $28,0001440 Renovation → assetSame
This month's rent, $4,5005300 Rent → expenseGone with the month

Why the split matters

Singapore tax treats computers and renovation completely differently from ordinary expenses:

  • Computers (Section 19A) can be written down in one year
  • Renovation (Section 14Q) is spread over three years, capped at S$300,000 per three-year period
  • Ordinary expenses are deducted as incurred

We deliberately split fixed assets into four accounts (1410 computers / 1420 furniture / 1430 office equipment / 1440 renovation) so they can be pulled out at filing time. Lump them together and someone re-sorts hundreds of receipts at year end.

When unsure: ask John, don't guess.


3. Accounts you'll use daily ​

Spending (expenses)

5300 Rent · 5400 Utilities · 5810 Stationery · 5820 Repairs · 5830 Marketing · 5840 Telecom · 5860 Travel · 5920 Teaching materials · 5930 Government fees · 5990 Sundry

Buying (assets)

1410 Computers & IT · 1420 Furniture & fittings · 1430 Office equipment · 1440 Renovation

Earning (revenue)

4150 Tuition income · 4100 Service revenue (corporate training)

Owing (liabilities)

2000 Trade payables · 2600 Due to director · 2610 Staff reimbursement payable


4. When nothing fits ​

Two options, in order:

  1. Use 5990 Sundry and move on. Getting it recorded beats getting it perfect — a missing entry is a real problem, a mis-classified one can be moved any time.
  2. Once you have a few of the same kind, tell John and let him decide whether to open a dedicated account. You can create one yourself (New Account), but ask first — otherwise the chart turns into a mess fast.

5. Nothing to do on this page ​

The chart is already set up (66 accounts). This step is just so you can read it; you'll use it constantly in the steps below.
