Double-entry bookkeeping is the system behind every set of accounts, from a one-person IFZA company to a listed group. It sounds technical, but the idea is simple, and once it clicks, reading your own accounts becomes much easier.
The one idea: every transaction has two sides
When money moves, something goes up and something else goes down (or up). Buying a laptop for cash: you have more equipment and less cash. Making a sale on credit: you have more sales and more money owed to you. Double-entry records both sides, every time.
The accounting equation
Assets = Liabilities + Equity
Everything the business owns (assets) was paid for either by borrowing (liabilities) or by the owners and past profits (equity). Every double-entry transaction keeps this equation in balance.
Debits and credits
Each transaction has equal debits and credits. What they do depends on the type of account:
| Account type | Debit | Credit |
|---|---|---|
| Assets (bank, receivables, stock, equipment) | Increase | Decrease |
| Expenses (rent, salaries, purchases) | Increase | Decrease |
| Liabilities (payables, VAT payable, loans) | Decrease | Increase |
| Equity (share capital, retained earnings) | Decrease | Increase |
| Income (sales) | Decrease | Increase |
"Debit" and "credit" just mean left and right. They don't mean good or bad.
Worked examples for a UAE business
1. Owner invests AED 50,000 of share capital
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| Bank | 50,000 | |
| Share capital | 50,000 |
2. Sale on credit: AED 10,000 + 5% VAT
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| Accounts receivable | 10,500 | |
| Sales | 10,000 | |
| VAT payable (output VAT) | 500 |
3. Customer pays the invoice
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| Bank | 10,500 | |
| Accounts receivable | 10,500 |
4. Rent paid: AED 6,000 + 5% VAT (commercial premises)
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| Rent expense | 6,000 | |
| VAT recoverable (input VAT) | 300 | |
| Bank | 6,300 |
5. Salaries paid through WPS: AED 15,000
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| Salaries expense | 15,000 | |
| Bank | 15,000 |
6. Paying VAT to the FTA for the quarter (output 500 − input 300)
| Account | Debit (AED) | Credit (AED) |
|---|---|---|
| VAT payable | 500 | |
| VAT recoverable | 300 | |
| Bank | 200 |
The trial balance
Add up all the debit balances and all the credit balances. In double-entry, they must be equal. A trial balance that doesn't balance means an entry is wrong. One that balances can still contain errors (a sale in the wrong account, for example), which is why monthly reviews and bank reconciliations matter.
Why it matters for UAE tax
- VAT: the VAT payable and VAT recoverable accounts give your return figures, and they can be checked against the transactions.
- Corporate Tax: your return starts from accounting profit, which comes from double-entry accounts.
- Audits: auditors and the FTA expect complete double-entry records.
Single-entry vs double-entry
A simple cash book (money in, money out) is single-entry. It's fine for a brand-new micro-business, but it can't show what you owe, what you're owed or the value of your assets. Read What Is Bookkeeping? for the basics.
