Renting out a flat, a garden cottage, or a holiday home can be a great way to build wealth. But many South African landlords are caught off guard when they learn that rental income is taxable. The South African Revenue Service (SARS) treats the rent you receive as part of your normal income, and you must declare it on your annual tax return.
The good news is that you do not pay tax on the full rent. You only pay tax on the profit — the rent left over after you subtract allowable running costs. This guide explains, in plain terms, what counts as rental income, which expenses you can claim, and how to work out what you owe.
What Counts as Rental Income?
Rental income is any money you earn from letting out a property. This includes the monthly rent your tenant pays, but it can also include other amounts, such as:
- A non-refundable deposit you get to keep.
- Payments for the use of furniture or appliances.
- Money a tenant pays you to cancel a lease early.
A normal damage deposit that you hold and later return is not income, because it is not really your money — you are holding it on the tenant's behalf. But if you keep part of it to cover damage, the amount you keep becomes income in that year.
To work out the tax on your total earnings once rental profit is added in, pop your figures into our salary calculator to see which tax bracket you land in.
Which Expenses Can You Deduct?
This is where most landlords leave money on the table. SARS lets you deduct any expense that you spent to earn the rental income. The most common deductions are:
- Bond interest: The interest portion of your home loan repayment is deductible. The portion that pays off the capital is not.
- Rates and taxes: Municipal rates charged on the property.
- Levies: If the property is in a sectional title scheme, the body corporate levies count.
- Insurance: Premiums on the building (not the contents of your own home).
- Repairs and maintenance: Fixing a leaking roof, repainting, or replacing a broken geyser.
- Agent commission: Fees you pay a letting agent to find tenants and manage the property.
- Garden services and security: Where these relate to the rented property.
Be careful with the difference between a repair and an improvement. Fixing something that broke is a repair, and you can deduct it straight away. Building a new room or adding a swimming pool is an improvement, and you cannot deduct it from rental income — though it may reduce your capital gains tax when you sell.
What Happens If You Make a Loss?
In the early years, especially with a large bond, your deductible expenses may be more than your rent. This creates a rental loss. In many cases, SARS lets you set this loss off against your other income, such as your salary, which reduces your overall tax bill.
However, SARS applies what is called the "ring-fencing" rule to certain taxpayers. If you are a high earner and the property is a holiday home or is let to a connected person at a low rent, the loss may be ring-fenced. That means you can only use it against future rental profits from the same property, not against your salary. Keep good records so you can show SARS the property is a genuine income-earning venture.
Capital Gains Tax When You Sell
Rental income tax is about the rent you earn each year. A separate tax applies when you eventually sell the property: capital gains tax (CGT). You pay CGT on the profit between what you paid and what you sell for, after subtracting costs like the transfer duty you paid on purchase and any improvements you made.
The annual capital gains exclusion for individuals stays at R40 000, and the inclusion rate is 40%. To estimate what you might owe on a future sale, use our capital gains tax calculator. If you are still budgeting for a purchase, our transfer duty calculator shows the upfront tax on the price you pay.
Provisional Tax: An Extra Step for Landlords
If your rental profit is more than a small amount and it is not taxed through the PAYE system on a payslip, SARS usually expects you to register as a provisional taxpayer. This means you estimate your income and pay tax twice a year — once in August and once in February — rather than waiting for the end of the tax year.
Provisional tax can feel daunting, but it simply spreads your payments out and avoids a nasty lump sum. Our estimated tax calculator helps you work out a sensible provisional payment so you do not under-pay and face a penalty.
Keeping Records the Right Way
SARS can ask you to prove every figure on your return, so good record-keeping is essential. Keep these for at least five years:
- Your lease agreements.
- Bank statements showing rent received.
- Invoices and receipts for every expense you claim.
- Your bond statement showing the interest paid each year.
- Municipal accounts for rates and levies.
A simple spreadsheet updated each month makes tax season painless. If you own more than one property, track each one separately so you can see which is actually making money.
The Bottom Line
Rental income is taxable, but smart landlords pay tax only on real profit. By claiming every legitimate expense — bond interest, rates, levies, insurance, and repairs — you keep your bill fair and low. Register for provisional tax if you need to, plan ahead for capital gains tax when you sell, and keep every receipt.
Before your next return, run your numbers through our salary calculator and estimated tax calculator so there are no surprises. A little planning today saves you both money and stress when SARS comes calling.
