Singapore vs Hong Kong Corporate Tax: Why Hong Kong's 8.25% Is Not the Whole Bill

At S$100,000 or S$200,000 of annual profit, a new Singapore company pays less tax than a Hong Kong one, despite the 17% headline against 8.25%. Add Hong Kong's mandatory audit and the gap widens. Hong Kong's total bill only drops below Singapore's from about S$270,000 of profit.

Savvy Platform incorporates Singapore companies for foreign founders and files the returns where these exemptions are claimed. SavvyStart covers incorporation, the nominee director, the company secretary and bank account support in one package.

The Headline Rates, and the Fine Print Under Them

Hong Kong:

• 8.25% on the first HK$2 million of assessable profits and 16.5% above, per the Inland Revenue Department's two-tiered regime, in place since the 2018/19 year of assessment
• If a company has connected entities, only the 1 nominated entity gets the two-tiered rates that year. The rest of the group pays 16.5% from the first dollar, under IRD rules
• No VAT, GST or sales tax, as PwC's tax summary confirms

Singapore:

• 17% flat, per PwC's Singapore summary
• Startup exemption for the first 3 years of assessment: 75% of the first S$100,000 of chargeable income and 50% of the next S$100,000 are exempt, up to S$125,000 a year, applied by IRAS automatically at filing
• From year 4, the partial exemption takes over: 75% of the first S$10,000 and 50% of the next S$190,000, up to S$102,500 of exempt income a year
• 9% GST registration becomes compulsory once taxable supplies pass S$1 million over 12 months

The connected-entities rule matters more than it looks. A founder running a holding company plus an operating company in Hong Kong gets the 8.25% band once, and the second entity pays 16.5% on everything.

The Worked Numbers: S$100,000 to S$500,000 of Profit

Conversions use HK$6.15 per Singapore dollar, the mid-market rate on 17 September 2026 per ValutaFX, which puts the HK$2 million band at about S$325,000. Audit costs use the HK$8,000 to HK$20,000 small-company range that Statrys reports, about S$1,300 to S$3,250.

The Singapore column works off chargeable income after exemption. At S$100,000, the startup exemption shelters S$75,000, and 17% applies to the remaining S$25,000. At S$500,000, it shelters the maximum S$125,000 and the other S$375,000 is taxed in full.

The Hong Kong column at S$500,000 splits the profit at the band: 8.25% on the first S$325,000 and 16.5% on the remaining S$175,000.

2 caveats sit behind the columns:

• The Singapore startup figures require a company incorporated in Singapore, tax resident there, with no more than 20 shareholders, and PwC notes the scheme excludes property development and investment holding companies
• The Hong Kong figures assume this is the group's 1 nominated entity: a second connected company at S$200,000 of profit pays 16.5% flat, S$33,000, double the nominated company's bill

In effective-rate terms, Hong Kong holds steady at 8.25% until the band runs out, then climbs to 11.1% at S$500,000. Singapore starts at 4.25% on S$100,000 in the exemption years and reaches 12.75% at S$500,000, so the 2 curves cross between S$200,000 and S$300,000.

Read across the rows and the pattern is plain. A startup-phase Singapore company beats Hong Kong on pure tax at S$100,000 and S$200,000, before the audit is even counted. From year 4 the 2 tax bills sit within a few hundred dollars of each other at S$200,000, and Hong Kong's audit is what separates the totals.

The Audit That Comes With the 8.25%

Hong Kong's Companies Ordinance requires audited financial statements from every company, with dormant companies as the only exemption, per the Companies Registry's FAQ. There's no size threshold, so a 1-person consultancy carries the same statutory audit as a listed group.

The reason is structural. Hong Kong companies file no financial statements with any public registry, so the audited accounts attached to the profits tax return are the IRD's only view of a company's finances, as Statrys explains in its audit guide. The audit exists to feed the tax system, which is why it never switches off.

Singapore runs the opposite model. IRAS assesses companies on filed returns, and ACRA exempts a private company from audit when it meets 2 of 3 criteria over the past 2 financial years: revenue of S$10 million or less, assets of S$10 million or less, and 50 or fewer employees.

An exempt Singapore company still prepares financial statements, files its annual return and holds its AGM. It just pays no auditor to sign them, and that difference recurs every year the company stays under the thresholds.

For a company earning S$100,000, Hong Kong's audit alone adds 16% to 39% on top of the tax. That's the line the 8.25% marketing leaves out.

GST at S$1 Million: Singapore's Own Fine Print

Fairness cuts both ways, and Singapore's version of hidden cost is GST. Registration becomes compulsory once taxable supplies pass S$1 million over 12 months, and the rate is 9%, per PwC's Singapore summary.

For a B2B business selling to GST-registered customers, the tax itself mostly passes through, since customers claim it back. The real cost is administrative: quarterly returns, invoicing changes and the cash-flow timing between charging GST and remitting it.

Hong Kong has no equivalent at any revenue level. PwC's summary states it plainly: Hong Kong has no VAT, goods and services tax, or sales tax. A consumer-facing business planning to pass S$1 million in Singapore revenue should price this section into the comparison before the audit savings.

The 0% Offshore Claim, Briefly

Founders often discount the whole comparison because Hong Kong's territorial system can tax offshore profits at 0%. That outcome is real but conditional: offshore status has to be claimed on the return and defended when the IRD reviews the source of each profit stream.

Since 1 January 2023, the Foreign-Sourced Income Exemption regime has added an economic substance test for entities in multinational groups, covering foreign dividends, interest, IP income and disposal gains, per the IRD. An entity claiming the exemption needs adequate staff and premises in Hong Kong for the activities that generate the income.

So the 0% case exists, and it's a defended position with conditions attached, which deserves its own analysis before anyone builds a structure on it.

Where Hong Kong Genuinely Wins on Tax

• From about S$240,000 of profit, Hong Kong's tax bill undercuts Singapore's even during the startup exemption years, and from about S$270,000 it stays lower with a mid-range audit included
• No GST at any revenue level, where Singapore's 9% registration duty arrives at S$1 million of taxable turnover
• A business that genuinely operates from elsewhere, with staff and decisions outside Hong Kong, can sustain an offshore claim and pay 0% on those profits, where Singapore would tax the same company as a resident
• Past the exemption bands, 16.5% beats 17% on the margin, before Singapore's treaty network of around 100 jurisdictions per IRAS's list enters the weighing

Businesses with profits comfortably past that crossover, and operators with real substance outside Hong Kong, have a genuine tax case for Hong Kong. The audit is the entry fee either way.

How Savvy Platform Handles the Singapore Tax Side

The Singapore numbers above only land if the filings behind them are done correctly. Savvy Platform covers that chain:

• Incorporation with ACRA, timed so the first 3 years of assessment capture the startup exemption from the first dollar of profit
• Accounting and corporate tax filing, with the startup or partial exemption applied at each year's return
• GST registration and filing support once taxable turnover approaches the S$1 million threshold
• The nominee director and company secretary that keep the company compliant while the founder is still abroad
• Bank account support with traditional Singapore banks and digital providers
• Employment Pass application when the founder relocates, which ends the nominee cost and puts the founder on their own payroll

SavvyStart bundles the incorporation essentials at a fixed price, with accounting and tax filing added as the company starts trading.

The Cheaper Tax System Depends on Your Profit Level

Compare total bills, not only headline rates. At S$100,000 of profit, a new Singapore company pays S$4,250 against Hong Kong's S$8,250 plus an audit of S$1,300 or more, and Hong Kong only takes the lead once profits pass roughly S$270,000 or a defensible offshore claim enters the picture.

If your profit projection sits in the S$100,000 to S$250,000 range for the first 3 years, run the Singapore numbers first. Send Savvy an enquiry with your projected profit and they'll scope the setup and the filings around it.

FAQ

Does every Hong Kong company get the 8.25% rate?

No. The 8.25% rate applies to the first HK$2 million of profits, and where a group has connected entities, only 1 nominated company can use the two-tiered rates each year. The others pay 16.5% on all profits.

How much tax does a new Singapore company pay on S$100,000 of profit?

S$4,250, an effective rate of 4.25%. The startup exemption removes 75% of the first S$100,000 of chargeable income from tax for the first 3 years of assessment, and IRAS applies it automatically when the return is filed.

Is Hong Kong's audit requirement really universal?

Yes. The Companies Ordinance requires audited financial statements from every Hong Kong company regardless of size, with dormant companies as the only exemption. A small company pays HK$8,000 to HK$20,000 a year for it.

When does GST start applying to a Singapore company?

Registration becomes compulsory once taxable supplies exceed S$1 million over a 12-month period, and the rate is 9%. Below that threshold, a Singapore company charges no GST at all.

Can a Hong Kong company pay 0% by billing only overseas clients?

Only if the IRD accepts an offshore claim on the profits, based on where the work was done and decisions were made. Since January 2023, entities in multinational groups also face an economic substance test under the FSIE regime, so the 0% outcome is claimed and defended, never automatic.
