Property tax on Hong Kong rental income: the basics for first-time landlords

Owning a rental property in Hong Kong can be a steady source of income, but it comes with a property tax obligation that catches many first-time landlords off guard. This guide walks through the core mechanics: what the Inland Revenue Department (IRD) treats as rental income, how assessable value is calculated, what deductions are typically allowed, and how to keep records that withstand scrutiny. If you are new to letting property in Hong Kong, treat this as a starting framework rather than a substitute for tailored advice.

What counts as rental income

For Hong Kong property tax purposes, rental income is broadly defined. The IRD looks at the gross rent you receive, or could reasonably be expected to receive, from letting out a property in Hong Kong.

In practice, this includes:

• The headline rent paid by your tenant under the tenancy agreement.
• Recoveries from the tenant for utilities, management fees, or rates that you have passed on.
• Lump sum premiums or key money received in connection with the grant of a lease or tenancy.
• The value of non-cash benefits, such as rent-free periods provided to a related party.

Service charges, building management fees recovered from tenants, and reimbursements for repairs you have arranged generally fall within the scope of rental income when the landlord receives them. Conversely, a genuine security deposit that is refundable and is in fact returned is not income.

If you rent out a room in your own home, or operate a mixed-use space, only the portion of rent attributable to the residential or letting portion is assessable. Carve this out carefully and keep a clear written basis for any allocation.

The assessment concept: assessable value

Hong Kong property tax is calculated on the assessable value of the property, not simply on the rent you receive. Assessable value is essentially the consideration paid by the tenant to the landlord for the right to use the property, less an allowance for irrecoverable rent.

The standard rate of property tax is 15% applied to the assessable value after the statutory deduction. The mechanism works as follows: start with the gross rental consideration, deduct irrecoverable rent to arrive at assessable value, apply the statutory deduction for repairs and outgoings, and then apply the 15% rate to the resulting net assessable value.

Two practical points follow:

• The tax base is not your net profit. It is the net assessable value after the statutory deduction.
• The tax is collected in advance (provisional property tax) and reconciled in the following year, so first-time landlords should expect a cash-flow impact in year one.

The statutory deduction for repairs and outgoings

Property tax is a schedular tax in Hong Kong, which means the legislation prescribes what is deductible rather than allowing general business expenses. The headline rule is that a 20% statutory allowance is granted on the assessable value to cover repairs and outgoings paid by the owner. This 20% deduction is statutory and automatic; you do not have to prove that you actually incurred the expenditure to claim it.

This narrow deductible framework is the key difference from profits tax. In particular:

• Mortgage interest is not deductible for property tax purposes, even though it is typically the largest expense a landlord faces.
• Building management fees, insurance, letting agent commissions, legal fees on lease renewal, and most other running costs are subsumed within the statutory allowance and are not separately deductible against property tax.

If you have substantial mortgage interest or ongoing costs and the property is held in a corporate vehicle or as part of a trade, it may be worth modelling whether profits tax treatment yields a better outcome. That decision is fact-specific and should be reviewed before filing.

Record-keeping

Hong Kong does not impose a statutory record-keeping period on individuals for property tax that mirrors the longer corporate retention rules, but the IRD can generally raise inquiries covering multiple prior years of assessment. Treat record-keeping as a practical necessity.

Keep, at minimum:

• The executed tenancy agreements and any subsequent variation or renewal.
• Records of rent received: bank statements, tenant receipts, and any rent-in-advance arrangements.
• Schedules of any deposits taken and refunded.
• A property ledger showing monthly rent, irrecoverable rent, and any tenant recoveries.
• Correspondence relating to rent default, with notes on any write-offs (and supporting evidence that recovery was attempted).
• Documentation supporting the calculation of the assessable value and the application of the 20% statutory allowance.

If you split a mixed-use property between letting and owner-occupation, keep documentation that supports the square-footage or room basis you used to apportion rent.

Pulling it together

For a first-time landlord, the working model is simple: identify the full consideration received from the tenant, reduce it by any irrecoverable rent to arrive at assessable value, apply the 20% statutory allowance for repairs and outgoings, and apply the 15% rate to the resulting net assessable value. If you are preparing computations across multiple years, confirm the rate and statutory mechanics that apply to each year of assessment with the IRD or a qualified adviser.
