What Is a SARS Section 18A Certificate and How Do You Get One?

A SARS section 18A certificate is an official document issued by a registered Public Benefit Organisation (PBO) that allows a donor to claim a tax deduction for their contribution. To qualify, the donation must be made to an approved entity that carries out specific public benefit activities. South African taxpayers can deduct these donations from their taxable income up to a limit of 10% of that income annually.

For South African small business owners, understanding the mechanics of a SARS section 18A certificate is more than just an exercise in corporate social responsibility; it is a strategic tax planning tool. Whether you are a sole trader or a private company (Pty) Ltd, navigating the South African Revenue Service (SARS) requirements correctly can lead to significant savings when your tax return is due. This guide explores the legal framework, the benefits for donors, and the strict requirements for organisations issuing these valuable documents.

What is a SARS section 18A certificate exactly?

A SARS section 18A certificate is a formal receipt issued by a SARS-approved Public Benefit Organisation (PBO) that enables a donor to deduct the value of their donation from their taxable income. It serves as legal proof for SARS that a donation was made to a qualifying cause under the Income Tax Act No. 58 of 1962. Without this specific certificate, a donation to a charity is generally considered a non-deductible personal or business expense.

Not all non-profit organisations (NPOs) can issue these certificates. While many South African charities do incredible work, only those that have applied for and received Section 18A status from the SARS Tax Exemption Unit (TEU) are authorised to provide this tax benefit to their supporters. This status is reserved for organisations involved in specific activities such as health care, education, poverty alleviation, and conservation.

For a small business, receiving this certificate means that the Rand value of your donation is subtracted from your total income before your tax is calculated. If your business earns R500,000 in taxable income and you donate R50,000 to an approved PBO, your tax will be calculated on R450,000, assuming you stay within the 10% threshold. This effectively reduces your tax liability while supporting a cause you care about.

How does a SARS section 18A certificate reduce your tax burden?

A SARS section 18A certificate reduces your tax burden by allowing you to claim a deduction of up to 10% of your taxable income for bona fide donations made to approved organisations. Any donation amount exceeding this 10% limit in a single tax year isn't lost; it can be carried forward to the succeeding tax year as a qualifying deduction. This ensures that large contributions still provide long-term tax relief for your business.

In the South African tax system, this is a 'deduction from income' rather than a 'tax credit.' A tax credit reduces the actual cash you owe SARS, whereas a deduction reduces the amount of income on which the tax rate is applied. For an SME taxed at the flat corporate rate of 27% (for years ending after 31 March 2023), a R10,000 donation with a valid certificate results in a R2,700 reduction in the actual tax payable.

It is important to note that the 10% limit is calculated based on taxable income before the donation deduction and before any retirement fund deductions. For individuals and sole traders, this is often simpler to calculate, but for companies, it requires careful monitoring by an accountant or using a platform like Smartbook to ensure the timing of the donation aligns with the financial year-end for maximum benefit.

Which organisations can issue a SARS section 18A certificate?

Only organisations registered as Public Benefit Organisations (PBOs) with the SARS Tax Exemption Unit and specifically approved under Section 18A of the Income Tax Act can issue these certificates. These organisations must carry out 'Part II' activities listed in the Ninth Schedule of the Act, which includes specific projects in education, welfare, and housing. Being a registered NPO with the Department of Social Development is not enough to qualify an entity to issue tax-deductible receipts.

The difference between NPO and PBO status

Many entrepreneurs confuse the term NPO with PBO. An NPO (Non-Profit Organisation) is a registration with the Department of Social Development that shows the entity is not for profit. A PBO (Public Benefit Organisation) is a tax status granted by SARS that exempts the organisation from paying income tax on certain activities. Only a subset of PBOs are granted Section 18A status, which is the specific power to issue tax-deductible certificates to donors.

Before making a donation, a business owner should ask the charity for their PBO number. You can verify this number on the SARS website or by requesting a copy of their SARS Section 18A approval letter. Verified compliance ensures that your business won't face issues during a SARS audit should you claim the deduction.

Qualifying activities for Section 18A status

SARS is very strict about what types of work qualify for tax-deductible donations. Examples include high-impact social sectors like:

1. Welfare and Humanitarian: Providing disaster relief or caring for the elderly and homeless.

2. Health Care: Operating clinics in underserved areas or providing free healthcare services.

3. Education and Development: Adult basic education, schools, and skills training for unemployed individuals.

4. Land and Housing: Building low-cost housing for the poor.

What are the mandatory requirements for a valid Section 18A certificate?

For a SARS section 18A certificate to be valid, it must contain specific legal information including the PBO's name, address, and reference number, the donor's name and address, the date and amount of the donation, and a statement that the receipt is issued for the purposes of Section 18A of the Income Tax Act. From 1 March 2023, SARS also requires additional data such as the donor's ID number or company registration number to facilitate third-party data reporting.

If any of these details are missing, SARS may disallow the deduction during a tax audit. As a business owner, you must ensure that when you receive a certificate, it reflects your full legal entity name as registered with CIPC and your correct Income Tax Reference Number. SARS has moved toward automating the reconciliation of these certificates, meaning they often expect this data to be pre-populated in your eFiling profile by the charity itself.

The shift to third-party data reporting

In a recent move to improve compliance, SARS now requires PBOs to submit 18A data directly to them via the IT3(d) process. This means that if you make a donation, the PBO should collect your tax details and report that donation to SARS. While you still need the physical or digital certificate for your records, the goal is for these deductions to appear automatically on your tax return, much like your medical aid or retirement fund contributions do today.

How do you get a SARS section 18A certificate as a donor?

To get a SARS section 18A certificate, you must make a 'bona fide' donation to an approved PBO and provide them with your tax information, including your name, tax reference number, and address. Once the funds are received, the organisation will process your details and issue a certificate, either immediately or at the end of the tax year. You should store this certificate safely, as it is a required supporting document for your annual tax return.

Steps to follow when donating

1. Verify the Organisation: Ask for their Section 18A letter from SARS before paying.

2. Make the Payment: Ensure the donation is a voluntary gift. Payments for goods or services (like buying a ticket to a charity gala) do not qualify for an 18A certificate.

3. Provide Your Details: Send the PBO your company registration name, tax number, and address. For individual sole traders, use your personal ID and tax number.

4. Request the Certificate: Don't wait until tax season in June or July. Request the certificate as soon as the payment is cleared.

What counts as a 'Bona Fide' donation?

A bona fide donation is a voluntary gift given out of benevolence where the donor receives no material benefit in return. If your business sponsors a local sports team and in return, the team puts your logo on their jersey, that is considered advertising or sponsorship, not a donation. Therefore, it would not qualify for a Section 18A certificate. However, the expense might still be deductible as a business marketing expense. It is vital to distinguish between charity (Section 18A) and marketing (Business Expense) for correct bookkeeping.

How to record your Section 18A donations in your bookkeeping

Properly categorising your donations in your accounting software is essential for clean financial reporting. You should create a specific account in your Chart of Accounts labeled 'Donations - Section 18A.' This makes it simple for your bookkeeper or tax practitioner to identify which payments are tax-deductible when preparing your Provisional Tax or annual returns. By separating these from general gifts or sponsorships, you ensure you are maximizing your tax efficiency without overstating your deductible expenses.

If you use a platform like Smartbook, you can easily attach a digital copy of the SARS section 18A certificate directly to the transaction in your ledger. This proactive approach saves hours of searching through emails when SARS inevitably asks for 'relevant material' to support your claim. Remember, SARS requires you to keep these records for at least five years.

Can you claim a deduction for non-cash donations?

Yes, you can claim a tax deduction for donations made in kind, such as equipment, stock, or assets. The value of the SARS section 18A certificate for a non-cash donation is generally determined by the cost price of the item if it is trading stock, or the lower of cost or fair market value for other assets. Professional services, such as a lawyer providing free legal advice to a charity, do not qualify for an 18A certificate as 'time' is not considered a payment or transfer of an asset under the Act.

Valuation of in-kind donations

If your business donates 10 laptops to a school, the value of the deduction is the cost at which you purchased those laptops (if you are a computer retailer) or the book value (if they were used assets). The PBO must still issue a certificate, but it will describe the goods donated rather than just stating a cash amount. It is the donor's responsibility to prove the value of the donated goods to SARS if questioned.

Common mistakes SMEs make with Section 18A certificates

One of the most frequent errors is claiming a deduction for a donation made to a school for 'school fees.' SARS explicitly prohibits the issuance of 18A certificates for school fees or any payment that covers the cost of a specific child's education. Another common mistake is trying to claim a certificate issued to a different entity. If you pay the donation from your personal bank account, you cannot claim it as a business expense in your Pty Ltd company return; the name on the certificate and the bank statement must match the taxpayer claiming the deduction.

Other mistakes include:

• Relying on a 'Certificate of Appreciation' instead of a formal Section 18A receipt.

• Claiming the deduction in the wrong tax year (donations are deductible in the year they are actually paid).

• Exceeding the 10% limit without carrying the balance over correctly to the following year.

Why your business should care about Section 18A certificates in 2026

As we navigate the 2026 tax year, the focus on ESG (Environmental, Social, and Governance) criteria is higher than ever. Beyond the tax savings, having a portfolio of Section 18A-compliant donations can improve your B-BBEE (Broad-Based Black Economic Empowerment) score, specifically under the Socio-Economic Development (SED) pillar. Most SED points require the recipient to be a PBO, and the 18A certificate serves as the primary evidence needed for your B-BBEE verification.

This creates a double win for South African SMEs: you reduce your tax liability through a legitimate SARS section 18A certificate and you improve your B-BBEE status, which can help you secure larger government or corporate contracts. Managing these moving parts requires accurate financial records and a clear understanding of South African tax law.
