IRAS Profit & Loss Statement: What Your Business Actually Needs to Prepare

Every year, Singapore businesses and sole proprietors are required to file their income tax with IRAS. And every year, a significant number get it wrong — not because they're trying to cheat, but because they're unclear about what IRAS actually requires.

The Profit & Loss (P&L) statement sits at the centre of your tax filing. It's the document that tells IRAS how much your business made, what it spent, and therefore how much taxable income you have. Getting it right isn't just about compliance — it's about making sure you only pay the tax you actually owe, not more.

What Is an IRAS Profit & Loss Statement?

A Profit & Loss statement (also called an income statement) is a summary of your business's revenues and expenses over a financial period — typically one year. The result is your net profit (or net loss), which is what IRAS taxes.

For Singapore tax purposes, the P&L follows this basic structure:

• Revenue — all income from your business activities
• Less: Cost of Goods Sold — direct costs of producing what you sell
• Equals: Gross Profit
• Less: Operating Expenses — overheads, salaries, rent, etc.
• Equals: Net Profit Before Tax

IRAS taxes your net profit (adjusted for any non-deductible expenses). The adjusted profit figure is what goes into your tax return.

Who Needs to Submit a P&L Statement?

The answer depends on your business structure and revenue size.

Companies (Pte Ltd)

All Singapore companies are required to prepare financial statements that comply with Singapore Financial Reporting Standards (SFRS). These include a P&L statement, balance sheet, and cash flow statement. They must be filed with ACRA annually and form the basis for IRAS corporate tax filing (Form C or Form C-S/C-S Lite).

Sole Proprietors and Partnerships

The requirements are simpler, and they depend on your annual revenue:

• Revenue above S$500,000: You must submit a full set of financial statements — P&L and balance sheet — prepared or certified by a qualified person. This is the same obligation as companies.
• Revenue S$200,000 to S$500,000: A certified P&L statement is required, but a balance sheet is not mandatory.
• Revenue below S$200,000: A simplified two-line statement is acceptable — just total revenue and net profit. However, IRAS can still request supporting records during an audit.

Note: "certified" means signed off by a qualified person — an approved company auditor or certified public accountant. For the simplified two-line statement below S$200,000, the business owner can self-certify. For the S$200,000–S$500,000 tier, IRAS expects a qualified accountant to sign off, not the owner. Check the IRAS website for current requirements as thresholds do change.

What Goes Into Revenue

Revenue sounds simple, but it catches people out. IRAS requires you to declare all business income — not just what was paid by bank transfer or invoice, but everything related to your business activities.

For most businesses, revenue includes:

• Sales of goods or products
• Service fees and professional fees
• Rental income from business assets
• Commission income
• Interest income from business bank accounts (though this is technically "other income")

Cash receipts must be included even if no invoice was issued. Platform payments (Grab, Foodpanda, Shopee, Carousell) must be included even if they're just transferred directly to your bank. In IRAS's view, if it's income from your business activities, it's taxable revenue.

What About Grants and Subsidies?

Government grants (like Enterprise Development Grant, PIC, or COVID-era payouts) are generally taxable income unless IRAS has specifically declared them as non-taxable. Check the specific grant's tax treatment — IRAS publishes this information for major schemes. When in doubt, declare it as income and let IRAS determine taxability.

Allowable vs Non-Allowable Expenses: The Critical Distinction

This is where most errors happen. Not every business expense is deductible against your taxable income. IRAS applies the "wholly and exclusively" test: an expense is only deductible if it was wholly and exclusively incurred in the production of income.

Allowable Expenses

These can be deducted from your revenue:

• Staff salaries, CPF contributions, SDL contributions
• Rent and utilities for business premises
• Cost of goods sold (materials, inventory, direct labour)
• Professional fees (legal, accounting, consulting)
• Advertising and marketing expenses
• Travel expenses (wholly for business purposes)
• Software subscriptions used for business
• Bad debts written off (specific amounts, not general provisions)
• Insurance premiums for business-related coverage

Non-Allowable Expenses

These cannot be deducted — they must be "added back" when calculating taxable income:

• Capital expenditure (buying equipment, renovating premises — use capital allowances instead)
• Personal expenses mixed in with business accounts
• Fines and penalties (parking fines, late filing penalties)
• Entertainment that is partly personal
• Depreciation (accounting depreciation is not tax-deductible — use capital allowances)
• Donations (these are handled separately via the tax exemption scheme)
• Owner drawings (your own salary as a sole proprietor is not an expense)

Capital Allowances: The Exception for Equipment

When you buy equipment (computers, machinery, commercial vehicles), you can't deduct the full cost in the year of purchase as an operating expense. Instead, IRAS allows you to claim capital allowances — a phased deduction over the useful life of the asset. For most small equipment, the "Section 19A" accelerated allowance lets you write it off over 1 or 3 years.

Common Mistakes Singapore Businesses Make on Their P&L

1. Including personal expenses

This is the most common issue for sole proprietors. Using the business account to pay for a family dinner, personal Amazon purchases, or personal insurance premiums and then claiming them as business expenses is both incorrect and risky. IRAS will disallow these deductions and may impose penalties.

2. Claiming accounting depreciation instead of capital allowances

Your accounting software might depreciate a laptop over 3 years at 33% per year. IRAS doesn't care about accounting depreciation — they want capital allowance claims instead. If you're submitting a P&L directly from your accounting software, you may need to add back accounting depreciation and separately claim the correct capital allowance.

3. Missing GST adjustments

If you're GST-registered, your revenue figures should be exclusive of GST (since the GST you collected belongs to IRAS, not you). And your input tax on expenses should be excluded from the expense amount you declare. If you're not careful about this, you'll either overstate revenue or overstate expenses.

4. Inconsistent years

IRAS flags unusual year-on-year changes. If your revenue was S$180,000 last year and S$60,000 this year with no obvious explanation, expect questions. Keep notes on major changes — lost a key client, took time off, changed business model — that explain significant swings.

5. Revenue cutoff errors

Under accrual accounting, revenue is recognised when earned (invoice date), not when paid. If you invoice a client on 31 December but get paid in January, that invoice is December revenue. Getting the period cutoff wrong creates inconsistencies that compound year after year.

How to Prepare Your P&L Correctly

For most small businesses and sole proprietors, a correctly prepared P&L doesn't require an accountant — but it does require disciplined record-keeping throughout the year.

The process:

1. Track all income as it's earned, categorised by type
2. Record every expense with a receipt or invoice, categorised by type
3. Separate capital vs operating expenses — flag any equipment purchases for capital allowance treatment
4. Reconcile against your bank statements — everything in your P&L should be verifiable against your bank
5. Adjust for non-allowable items before arriving at the taxable profit figure

Tools like app.kevinchia.sg automate most of this: receipts are captured and categorised automatically, your P&L is updated in real time, and you can see your taxable profit position at any time — not just at year-end when it's too late to do anything about it.

The Right Mindset for IRAS Filing

Filing your tax return accurately is both a legal obligation and a financial interest. The goal isn't to minimise what you declare — it's to declare exactly what you earned, claim every legitimate deduction, and pay the correct amount of tax. Businesses that take this approach rarely have problems with IRAS. Businesses that try to push the boundaries on deductions or understate income face penalties that far outweigh any tax saved.

IRAS has access to third-party data — CPF contribution records, banking information, payment platform data, and more. The chances of material omissions going undetected are much lower than many small business owners assume.

Frequently Asked Questions

Who needs a certified P&L statement in Singapore?

Businesses and sole proprietors with revenue above S$500,000 need a full certified P&L and balance sheet. Between S$200,000 and S$500,000, a certified P&L is required but a balance sheet is not mandatory. Below S$200,000, a simplified two-line statement of revenue and net profit is acceptable.

Are government grants taxable income?

Generally yes, unless IRAS has specifically declared a grant non-taxable. Check the specific grant's tax treatment, and when in doubt, declare it as income and let IRAS determine taxability.

Can I deduct the full cost of equipment in the year I buy it?

No. Equipment purchases are claimed through capital allowances, a phased deduction over the asset's useful life, rather than as a full operating expense. The Section 19A accelerated allowance lets you write off most small equipment over 1 or 3 years.

Is accounting depreciation tax-deductible in Singapore?

No. IRAS doesn't accept accounting depreciation as a deduction. If your P&L includes it, you need to add it back and claim the correct capital allowance separately instead.

What is the "wholly and exclusively" test for expenses?

An expense is only deductible if it was wholly and exclusively incurred in the production of income. Personal expenses mixed into business accounts, fines, and capital expenditure don't meet this test and must be added back when calculating taxable income.
