Rental Income Tax Calculator — South Africa

What Is Rental Income Tax in South Africa?

There is no separate "rental tax" in South Africa. SARS treats rent you receive as ordinary income — it's added to your salary, business profit or any other taxable income for the year and taxed together at your normal marginal rate. What changes from one landlord to the next isn't the rate, it's how much of that rental income actually gets included after deductible expenses, and how it interacts with the rest of your income.

This calculator is built to answer the question most landlords actually have: not "what's my whole tax bill", but "what does owning this rental property actually add to it". It isolates the rand value of tax caused specifically by the rental income, on top of what you'd owe on your other income alone — and shows the provisional tax (IRP6) payments that follow from it. On your annual return, rental profit is declared under SARS source code 4210, and a rental loss under 4211.

How Rental Income Is Taxed — Step by Step

Start with your net rental income: gross rent received minus the Section 11(a) expenses you're entitled to deduct. That net figure is added to your other taxable income for the year to give your combined taxable income, which is run through the SARS individual tax brackets and reduced by your age-based rebate to give your total tax liability.

The tax specifically caused by the rental income is the difference between tax on your combined income and tax on your other income alone — that gap is what this calculator reports as the headline figure. It matters because South Africa's brackets are progressive: stacking rental income on top of a salary can push part of your income into a higher bracket than either income would reach on its own, so the rental income's true tax cost is often higher than simply "expenses saved at your marginal rate" would suggest.

What You Can Deduct Against Rental Income (Section 11(a))

Confirmed directly from SARS's guidance on rental income, the following are deductible against rent received in the year they're incurred:

• Rates and taxes
• Bond interest (not the capital repayment portion)
• Advertising and agency / managing-agent fees
• Homeowner's insurance (not contents or bond life cover)
• Garden services
• Repairs and maintenance (not capital improvements)
• Security
• Property levies

Capital improvements — a new roof, an extension, a renovation — aren't deductible against rental income at all. They instead add to your base cost for capital gains tax when you eventually sell, so keep the invoices either way. Use the Capital Gains Tax Calculator when that day comes. If you only let part of the property — a granny flat, for example — expenses must be apportioned by floor area between the rented and non-rented portions.

Do You Need to Register as a Provisional Taxpayer?

SARS exempts you from provisional tax if your combined passive income — rental income, interest and foreign dividends — is below R30,000 for the tax year, provided you have no business income. Most landlords with a single investment property clear that threshold quickly: R30,000 a year is just R2,500 a month in gross rent, well under what most SA rental properties earn — check your own numbers with the Rental Yield Calculator.

This is also why the "already taxed via PAYE?" question matters so much. A salaried employee with one rental property is the far more common case than someone whose only income is the property itself — and for that person, provisional tax isn't recalculating their entire tax liability from scratch. It's the top-up on the portion PAYE doesn't already cover: the tax specifically attributable to the rental income.

Rental Income Tax — Worked Example

A landlord earns R180,000 in gross annual rent, with R54,000 in Section 11(a) deductible expenses (rates, bond interest, agent fee, insurance, repairs). Their salary is R450,000 a year, already fully taxed via PAYE, and they're under 65:

• Net rental income: R180,000 − R54,000 = R126,000
• Combined taxable income: R450,000 + R126,000 = R576,000
• Tax on combined income (2027 brackets, primary rebate): R124,267
• Tax on the R450,000 salary alone: R82,917
• Tax attributable to the rental income: R124,267 − R82,917 = R41,350
• Effective rate on the net rental income: 32.8%
• Provisional tax (PAYE already covers the salary): R20,675 due 31 Aug 2026, R20,675 due 26 Feb 2027

Notice the rental income's effective tax rate (32.8%) is well above what this landlord's 36% marginal bracket ceiling might suggest at a glance — it reflects that stacking R126,000 on top of a R450,000 salary pushes a slice of income from the 31% bracket into the 36% bracket, a cost that's easy to underestimate if you only think in terms of your salary's tax bracket alone.

Rental Losses and Ring-Fencing

If your deductible expenses exceed your rental income for the year, the loss can generally reduce your other taxable income — lowering your overall tax bill, not just your rental-related liability. SARS applies anti-avoidance "ring-fencing" rules, however, where a letting activity that consistently runs at a loss and isn't operated as a genuine trade with a reasonable prospect of profit can have that loss suspended rather than offset immediately against other income. If your property has run at a loss for several consecutive tax years, get advice from a registered tax practitioner before assuming the loss will offset your salary this year.
