Rental Income Tax Calculator South Africa 2026/2027

Official SARS expense categories · Source: SARS

Calculate your net rental profit and its tax impact, using the official SARS list of deductible expenses.

Step 1 — How much of the property is let?

Apportionment percentage: 0.00%

Step 2 — Rental income

Step 3 — Deductible expenses

Enter your total expenses. Use the toggle to indicate if an expense applies to the whole property (apportioned) or only the let area (claimed in full).

Not deductible against rental income — but added to your property's CGT base cost for when you eventually sell.

Tax Impact

To calculate the estimated tax on your rental profit, provide your other taxable income.

Gross rental income R 0
Total deductible expenses R 0
Net rental profit (Loss) R 0
Rental Loss (Source code 4211): This loss may be set off against your other income, provided you can show you are conducting a bona fide trade and it is not "ring-fenced" under SARS anti-avoidance rules.
Marginal tax rate applied 0%
Estimated additional tax R 0
Rental income isn't taxed at a special rate. It's simply added to your other income and taxed at your normal marginal rate — there's no separate "rental tax." This calculator shows your net rental profit, then estimates the additional tax that profit creates given your other income.

This calculator provides an estimate only, based on the official SARS list of permissible rental expenses. It does not constitute tax advice and does not cover every possible scenario (such as ring-fencing rules for habitual loss-making rentals, or VAT registration as a short-term letting business). Consult a registered tax practitioner for guidance specific to your situation.

Which rental expenses can you deduct?

Permissible expense Note
Rates and taxes Municipal rates and property taxes
Bond interest The interest portion of your mortgage repayment — not the capital repayment
Advertisements Costs of advertising the property for rent
Agency fees Estate agent letting/management fees
Insurance Homeowner's insurance only — not household contents insurance, and not bond insurance
Garden services
Repairs In respect of the area let
Security and property levies

What's NOT deductible:
Capital expenses — most commonly, improvements to the property — are not deductible against rental income. The value of an improvement is instead added to the property's CGT base cost, reducing the eventual capital gain (or increasing the loss) when the property is sold.

Repairs vs. improvements — the test:
Repairs/maintenance: restoring an asset to its original condition after damage or deterioration — deductible.
Improvements: creating a better asset than existed before — not deductible against rental income (but added to CGT base cost).

SARS notes that the specific facts and circumstances of each case must be examined to determine which category applies.

A note on VAT:
Residential accommodation letting is an exempt supply for VAT purposes. This means you cannot register for VAT on residential rental income, and you cannot deduct any VAT you paid on related expenses.

Worked example — letting part of your home (SARS's own example)

The scenario:
Z lets two rooms (each with its own en-suite bathroom) within Z's main home, on a bed-and-breakfast basis. The total area of the dwelling is 420m²; the area let is 120m² — meaning 28.57% of the property is let (120 ÷ 420 × 100).
Z's total rental income for the year was R50,000.

The expenses and their treatment:

Expense Total (R) Apportioned to let area (28.57%)
Rates and taxes R9,600 R2,743
Garden services R10,000 R2,857
Security R2,000 R571
Interest on bond R60,000 R17,142
Advertisements (not apportioned — let-area-specific) R1,000 R1,000
Insurance R6,000 R1,714
Improvements to garage (not deductible at all) R5,000 R0
Repairs to water-damaged carpets (not apportioned — let-area-specific) R12,000 R12,000
Total R105,600 R38,027

Source: SARS — Tax on Rental Income page (Z's worked example, reproduced exactly)

The result:
Total deductible expenses: R38,027
Rental income: R50,000 − R38,027 = R11,973 taxable rental profit

This R11,973 is declared under source code 4210 and added to Z's other income for the year, to be taxed at Z's normal marginal rate.

Why some expenses weren't apportioned:
Advertisements were incurred 100% to advertise the let rooms specifically — claimed in full.
Repairs to water-damaged carpets related specifically to the let area — claimed in full, no apportionment needed.
Improvements to the garage are capital/private expenses entirely unrelated to the production of rental income — not deductible at all, at any percentage.

Rental losses, community of property, and non-resident landlords

If your expenses exceed your rental income:
The resulting loss may be set off against your other income — provided you can show you're conducting a bona fide trade through the letting, and provided the loss isn't "ring-fenced" under SARS's anti-avoidance rules (which can restrict habitual loss-making activities from offsetting other income indefinitely).

Married in community of property:
If the rental property falls into the joint estate of a marriage in community of property, the rental profit or loss is split 50:50 between both spouses. You declare the full amount after expenses on your own return — SARS apportions the 50:50 split programmatically; you don't need to manually halve the figures yourself.

Non-resident landlords:
If you're a non-resident earning rental income from South African property, that income is subject to normal South African income tax — the source of rental income is generally where the property is physically used. The same permissible expenses (rates and taxes, bond interest, insurance, repairs) may be claimed, subject to the same conditions as for residents.

Frequently Asked Questions

Rental income is added to your other income and taxed at your marginal rate. Deduct permissible expenses to find your net rental profit, which is declared under source code 4210 (or 4211 for a loss).
Yes. Bond interest is a permissible expense for a genuine rental property and is fully deductible, subject to apportionment if only part of the property is let.
Only homeowner's insurance covering the building is deductible. Household contents and bond insurance cannot be claimed.
Expenses relating to the whole property must be apportioned based on the let area. Expenses specifically for the let area (e.g., repairs to that room) are claimed in full.
Renovations are capital in nature and not currently deductible, but are added to the property's base cost for capital gains tax. Repairs restoring the property to its original condition are fully deductible.
The loss can generally be set off against other income, provided you are conducting a bona fide trade and the loss is not ring-fenced under SARS's anti-avoidance rules.
