Hong Kong is unusual in computing your salaries tax twice and charging you the lower result, which means there is no single rate that describes your position and no threshold at which you simply move up a bracket. The progressive computation applies 2%, 6%, 10%, 14%, and 17% to successive HKD 50,000 bands of net chargeable income, that is income after deductions and after personal allowances. The standard rate computation ignores allowances entirely and applies a flat rate to net income after deductions only, and from the 2024/25 year of assessment that standard rate became two-tiered, 15% on the first HKD 5 million of net income and 16% on the remainder. The crossover between the two computations typically falls somewhere around HKD 2 million of income for a single taxpayer with no dependants, and it shifts upward for every allowance you can claim. Personal assessment adds a third option for anyone with business or rental income. This calculator runs both computations explicitly rather than assuming which one wins.

Key Regulatory Parameters & Frameworks (YA 2026)

Rule 01

The Progressive Bands

Net chargeable income is taxed at 2% on the first HKD 50,000, 6% on the next HKD 50,000, 10% on the next HKD 50,000, and 14% on the next HKD 50,000, with 17% on the remainder. Cumulative tax therefore reaches HKD 16,000 at HKD 200,000 of net chargeable income, after which every further dollar attracts 17%. Because the bands are narrow, the progressive computation approaches a near-flat 17% quite quickly for higher earners, which is precisely why the standard rate eventually undercuts it.

Rule 02

The Two-Tiered Standard Rate

From the 2024/25 year of assessment the standard rate is 15% on the first HKD 5,000,000 of net income and 16% above that, replacing the previous single 15% rate. Net income for this purpose is assessable income less deductions but before any personal allowances, which is the key structural difference from the progressive computation. The Inland Revenue Department applies whichever of the two computations produces the lower tax, without any election being required.

Rule 03

Where the Crossover Falls

The more allowances you claim, the higher your income must be before the standard rate becomes the cheaper answer. A single taxpayer claiming only the basic allowance typically crosses over around HKD 2 million of net income, whereas a married taxpayer claiming joint assessment with several children and dependent parents may remain on the progressive computation at considerably higher income. This is why two colleagues on the same salary can be assessed under different computations entirely.

Rule 04

Personal Assessment and Joint Assessment Elections

A person with income chargeable to more than one of salaries tax, profits tax, and property tax may elect personal assessment, which aggregates the lot into a single progressive computation with allowances and allows interest on money borrowed to produce rental income to be set off. Married couples may elect joint assessment, where incomes are aggregated and the married person's allowance applied, which helps where one spouse's income is too low to absorb their own allowances. Both elections are made in the return and are worth testing rather than assuming.

Rule 05

Budget Reductions, Filing, and Objections

The Financial Secretary has in most recent years announced a one-off reduction of salaries tax, expressed as a percentage of the final tax subject to a cash ceiling that has ranged from a few thousand Hong Kong dollars down to HKD 1,500 in recent Budgets. It is applied automatically and is not guaranteed for any future year. Individual tax returns, form BIR60, are usually issued in early May with one month to file, extended by a further month for electronic filing, and an objection to an assessment must be lodged in writing within one month of the notice.

Two-Tier Salaries Tax Comparison at HKD 2,000,000

Scenario Context: Single Hong Kong taxpayer with HKD 2,000,000 of assessable income for the year of assessment, claiming the basic allowance of HKD 132,000 and deducting HKD 18,000 of mandatory MPF contributions, with no other deductions.

Calculation Stage	Computed Value
Assessable income	HKD 2,000,000
Less mandatory MPF contributions	HKD 18,000, giving net income of HKD 1,982,000
Standard rate computation at 15% on net income (within the first HKD 5 million tier)	HKD 297,300
Less basic allowance for the progressive computation	HKD 132,000, giving net chargeable income of HKD 1,850,000
Progressive: cumulative tax on the first HKD 200,000 across the 2%, 6%, 10%, and 14% bands	HKD 16,000
Progressive: remaining HKD 1,650,000 at 17%	HKD 280,500
Progressive computation total	HKD 296,500

Final Deducted Result:The IRD charges the lower figure, so HKD 296,500 is assessed rather than HKD 297,300. This income level sits almost exactly at the crossover for a single taxpayer with only the basic allowance: a little more income, or one fewer allowance, and the standard rate would win instead. Any Budget tax reduction announced for the year would then be applied to this figure, and provisional tax for the following year is demanded alongside it.

Frequently Asked Questions (FAQ)

When is salaries tax due?▼

The IRD issues demand notes from around September or October, and the amount is normally payable in two instalments, typically in January and April. The first instalment is the larger one because it covers the final tax for the year just assessed plus roughly three quarters of the provisional tax for the year ahead. Late payment attracts a 5% surcharge, with a further 10% on amounts still outstanding six months later, so agreeing an instalment arrangement in advance is far cheaper than simply paying late.

How do I know whether I will be taxed at the progressive or standard rate?▼

You do not choose; the IRD computes both and charges the lower. The practical rule is that allowances only help under the progressive computation, so the more dependants you claim, the higher your income can go before the standard rate becomes cheaper. A single taxpayer with only the basic allowance generally crosses over around HKD 2 million of net income, while a married taxpayer with children and dependent parents may stay on the progressive computation well beyond that.

Should I elect personal assessment?▼

It is worth testing if you have income from more than one head of charge, typically salary plus rental income or a small business. Personal assessment aggregates everything into one progressive computation with allowances and permits the deduction of interest on money borrowed to produce rental income, which property tax on its own does not allow. It is not always better: where all your income is already salary, personal assessment changes nothing, and where profits are high it can push more income into the 17% band.

Will there be a tax reduction this year?▼

It depends on the Budget. The Financial Secretary has announced a one-off reduction of salaries tax in most recent years, expressed as a percentage of the final tax with a cash cap, and that cap has trended downward, reaching HKD 1,500 in recent years from much higher ceilings previously. It is applied automatically to the final tax and does not reduce the provisional tax demanded for the following year. Because it is discretionary, it should never be assumed in forward planning.
