Urban renewal has long been a challenge in South Africa’s major cities, where aging infrastructure and urban decay discourage much-needed investment. To address this problem, government introduced the pivotal Urban Development Zone (‘UDZ’) incentive under section 13quat of the Income Tax Act, which creates a targeted tax benefit for property investors and developers. Understanding this incentive is essential to identifying – and maximising – investment and development opportunities.
The legal framework: Section 13quat of the Income Tax Act
Designed to encourage private-sector participation in the redevelopment of inner-city areas, section 13quat of the Income Tax Act (‘the Act’) forms the legal basis of the UDZ incentive. Its objective is twofold: To combat urban decline and stimulate new commercial and residential activity in designated development zones.
Section 13quat enables taxpayers to claim accelerated depreciation allowances on the costs associated with erecting, adding to, extending or improving qualifying buildings located with a defined UDZ. This effectively reduces taxable income, improves cash flow, and enhances investment viability.
To qualify, taxpayers must meet certain statutory requirements, namely the building must comply with specific definitional prerequisites, be owned by the taxpayer, be located within a designated UDZ, and be used solely for trade purposes.
These core requirements are outlined below.
Building requirement
To benefit from this incentive, the taxpayer must have:
- Erected an entirely new residential or commercial building; or
- Extended, added to, or improved an existing residential or commercial building or part of such a building representing a floor area of at least 1 000m2 ; or
- Purchased a building or part of a building directly from a developer who has erected, extended, added to, or improved either an entire building or a part of a building representing a floor area of at least 1 000m2 and not previously claimed any UDZ deduction on the building or part thereof. Crucially, the developer must have incurred expenditure on these improvements, which is equal to at least 20% of the purchase price paid by the purchaser for the building or part thereof.
UDZ requirement
To qualify for the incentive, the property – or part of the building – must be located within an officially designated urban development zone, as proclaimed by the National Treasury in the Government Gazette. Current UDZs include The City of Cape Town, Johannesburg Metro, Ekurhuleni, Tshwane Metro, and Nelson Mandela Bay.
Owner requirement
The taxpayer must own the building – or part thereof – that was erected, added to, extended, or improved to claim the UDZ incentive. In practice, this prevents non-owners, including those leasing a newly constructed building, from claiming unwarranted construction-related costs.
Trade requirement
In addition to being located within an established UDZ, the building must be used solely by the taxpayer in the course of carrying on a trade. While there is no single test to determine when a taxpayer has commenced carrying on a trade, each case will depend on the prevailing facts and circumstances. Crucially, a taxpayer who ceases to trade cannot claim the UDZ incentive in the succeeding year of assessment in which trading activities ended.
Date requirement
Importantly, the taxpayer must comply with the following date-specific requirements:
The erection, addition to, extension, or improvement of the building must have taken place:
- On or after the date on which the demarcated area within which the building is located has been gazetted; and
- In accordance with an agreement formally concluded by all parties on or after that date.
The sale agreement must have been concluded no earlier than 8th November 2005. In addition, the building – or the relevant part thereof – must have been brought into use solely for the purposes of the taxpayer’s trade on or before 31st March 2030, which was formally extended following the 2025 Budget Review.
What costs can be claimed?
Under the UDZ incentive, taxpayers can claim various costs actually incurred in erecting, adding to, extending, or improving a building or a component of that building, including:
- Demolition costs;
- Excavation costs to facilitate the erection, extension, addition, or improvement of said building; and
- Costs connected to structures or works directly adjoining the building – or a portion thereof – for the purpose of providing water, electricity, or parking, facilities for waste disposal, drainage or security, or access to the building, including its frontage.
In practice, these costs might include construction work, architectural and appropriate fees, or parking for the building. Conversely, expenses connected to the purchase price of the land, borrowing or financing costs, and transfer-related costs, including transfer duty, will not qualify as deductible.
The City of Cape Town: A model of success
Over the years, the UDZ framework has been instrumental in attracting billions of Rands in private capital. Since Cape Town implemented the incentive in 2004, the results have been tangible. From 2006 onwards, the City estimates that more than 2 000 applications have been submitted, with claims amounting to nearly R6.7 billion. Acquisitions have exceeded R2.8 billion, refurbishments near R2.3 billion, and new construction projects have been valued at R747 million. These impressive statistics demonstrate that the incentive has consistently attracted large-scale investment, which breathes new life into areas that might otherwise face urban stagnation.
Looking ahead
At its core, section 13quat is a tax-saving mechanism that reduces barriers to entry and makes investment in high-risk or neglected areas more attractive. The extension of the UDZ incentive to 2030 is a clear signal of government’s continued commitment to urban regeneration. For developers and property investors, it offers a longer planning horizon and an opportunity to reduce taxable income, improve cash flow, and align profitable ventures with social and economic impact.
