This comprehensive guide explains every major tax deduction available to South African taxpayers in 2025/2026, including retirement contributions, medical expenses, donations, and business-related deductions. Learn how to maximize your tax savings while staying fully compliant with SARS regulations.

Understanding Tax Deductions vs Tax Credits

Before diving into specific deductions, it's important to understand the difference between tax deductions and tax credits.

Tax Deductions

Tax deductions reduce your taxable income before tax is calculated. They're subtracted from your gross income to arrive at your taxable income.

Example: If you earn R600,000 annually and contribute R80,000 to a retirement annuity:

• Gross income: R600,000

• Retirement deduction: R80,000

• Taxable income: R520,000

The tax is then calculated on R520,000 instead of R600,000, saving you approximately R28,800 in tax (at 36% marginal rate).

Tax Credits

Tax credits reduce your tax liability after tax has been calculated. They're subtracted directly from the tax you owe.

Example: Medical aid tax credits of R4,368/year (R364/month):

• Tax calculated on taxable income: R100,000

• Medical aid tax credit: -R4,368

• Final tax owed: R95,632

1. Retirement Annuity Contributions

Retirement annuity (RA) contributions are the single most powerful tax deduction available to South African taxpayers.

Deduction Limits

For Tax Year 2025/2026:

• You can deduct 27.5% of taxable income OR

• R350,000 per year

• Whichever is lower

Important: This limit applies to total retirement contributions including:

• Retirement annuities

• Pension fund contributions

• Provident fund contributions

How Much Can You Save?

Tax savings depend on your marginal tax rate:

Marginal Rate	Annual Contribution	Tax Saving
18%	R50,000	R9,000
26%	R80,000	R20,800
31%	R100,000	R31,000
36%	R120,000	R43,200
41%	R150,000	R61,500
45%	R200,000	R90,000

Calculation Example

Scenario: Annual income R600,000, marginal tax rate 36%

• Maximum deduction: R600,000 × 27.5% = R165,000

• Contribution: R120,000 (within limit)

• Tax saving: R120,000 × 36% = R43,200

Important Rules

1. Annual Contribution Limit

• No limit on how much you can contribute

• But only 27.5% of income (max R350,000) is tax deductible

• Excess contributions are carried forward to future tax years

2. Carry Forward Provisions

• Unused deductions don't expire

• Carried forward indefinitely

• Applied in future years when you have taxable income

3. Withdrawal Restrictions

• Cannot withdraw before age 55 (except emigration, death, disability)

• Only 1/3 can be taken as lump sum at retirement

• Remaining 2/3 must purchase annuity (pension)

Optimization Strategy

For High Earners (36%+ bracket):

• Maximize contributions to full 27.5% limit

• Immediate 36-45% "return" via tax savings

• Plus investment growth is tax-free until retirement

For Middle Earners (26-31% bracket):

• Contribute as much as affordable

• 26-31% immediate tax saving

• Balance current needs vs retirement security

For Lower Earners (18% bracket):

• Consider tax-free savings accounts first (better liquidity)

• Then RAs for longer-term savings

• 18% tax saving still worthwhile

2. Medical Aid Tax Credits

Medical aid tax credits directly reduce your tax liability. These are credits, not deductions.

2025/2026 Medical Aid Credits

Monthly Credits:

• Main member: R364 (R4,368/year)

• First dependent: R364 (R4,368/year)

• Additional dependents: R246 each (R2,952/year each)

Example Calculations:

Single person:

• Annual credit: R364 × 12 = R4,368

Couple (2 members):

• Annual credit: (R364 + R364) × 12 = R8,736

Family of 4:

• Annual credit: (R364 + R364 + R246 + R246) × 12 = R14,640

Additional Medical Expense Deductions

Beyond the standard credits, you can deduct additional medical expenses if:

For Taxpayers 65+ OR with Disability:

• ALL out-of-pocket medical expenses are deductible

• No limits or thresholds

For Taxpayers Under 65:

• Can deduct medical expenses exceeding 3 times medical aid credits

• Plus out-of-pocket expenses exceeding 7.5% of taxable income

Calculation Example: Under 65

Scenario:

• Taxable income: R500,000

• Medical aid members: 3 (self + 2)

• Annual medical aid credits: (R364 + R364 + R246) × 12 = R11,688

• Medical aid contributions: R48,000

• Out-of-pocket medical expenses: R25,000

Step 1: Calculate 3 times medical aid credits

• 3 × R11,688 = R35,064

Step 2: Medical expenses exceeding credits

• Medical aid paid: R48,000

• Less: 3 × credits: -R35,064

• Excess: R12,936

Step 3: Out-of-pocket exceeding 7.5% of income

• Out-of-pocket: R25,000

• Less: 7.5% × R500,000: -R37,500

• Excess: R0 (threshold not exceeded)

Total additional deduction: R12,936

Tax saving: R12,936 × 36% (marginal rate) = R4,657

Qualifying Medical Expenses

Fully Deductible:

• Medical aid contributions

• Hospital expenses not covered by medical aid

• Specialist consultations

• Prescription medications

• Dental and orthodontic treatment

• Optometry and prescription glasses

• Physiotherapy and other therapies

• Medical equipment (wheelchairs, crutches, etc.)

Not Deductible:

• Over-the-counter medications

• Cosmetic procedures

• Gym memberships

• Health supplements and vitamins

Record Keeping

Keep detailed records:

• Medical aid statements and tax certificates

• Receipts for all out-of-pocket expenses

• Invoices from medical practitioners

• Prescriptions for medications

3. Donations to Public Benefit Organizations

Donations to registered Section 18A organizations are tax deductible.

Deduction Limits

2025/2026 Limits:

• 10% of taxable income (before retirement deduction)

• No rand value cap

Qualifying Organizations

Donations must be to organizations with Section 18A status:

• Registered charities

• Religious organizations

• Educational institutions

• Public benefit organizations (PBOs)

• Certain animal welfare organizations

Always request a Section 18A certificate from the organization. Without this certificate, you cannot claim the deduction.

Calculation Example

Scenario:

• Taxable income (before retirement deduction): R600,000

• Marginal tax rate: 36%

Maximum deductible donation:

• R600,000 × 10% = R60,000

If you donate R50,000:

• Tax saving: R50,000 × 36% = R18,000

• Net cost of donation: R50,000 - R18,000 = R32,000

Essentially, SARS subsidizes 36% of your donation through tax relief.

Strategic Donation Planning

End of Tax Year:

• Make donations before end of February

• Ensures deduction in current tax year

• Particularly valuable if you had a high-income year

Regular Monthly Donations:

• Debit order donations throughout the year

• Get annual Section 18A certificate

• Claim full amount on tax return

Once-Off Large Donations:

• Consider timing for high-income years

• Maximizes tax benefit at highest marginal rate

4. Business and Employment-Related Deductions

If you're employed, self-employed, or run a business, various work-related expenses are deductible.

Home Office Deduction

If you work from home (even partially), you can claim a portion of home expenses.

1. Actual Cost Method:

• Measure your office as % of total home size

• Claim that % of:

  • Rent or bond interest
  • Rates and taxes
  • Electricity and water
  • Home insurance
  • Repairs and maintenance

Example:

• Office: 15m² of 150m² home = 10%

• Annual home expenses: R120,000

• Home office deduction: R120,000 × 10% = R12,000

• Tax saving (at 36%): R4,320

2. Simplified Method (SARS):

• R3.20 per square meter per month (2025/2026)

• Office: 15m²

• Monthly deduction: 15 × R3.20 = R48

• Annual deduction: R48 × 12 = R576

The actual cost method usually provides higher deductions.

Requirements:

• Office must be used regularly and exclusively for work

• Improves cash flow throughout year

• Avoid overpaying and waiting for refunds

Year-End Bonus Planning

Receive December/January bonus?

• Make large RA contribution in same tax year

• Offset bonus tax immediately

• Reduces PAYE on bonus

Example:

• Bonus: R100,000

• Tax on bonus (at 41%): R41,000

• RA contribution: R100,000

• Tax saving: R41,000

• Net cost of R100,000 RA: R59,000

Retirement Tax Planning

In retirement, different deductions apply:

• No more RA contributions

• But: Medical expense deductions increase significantly

• All out-of-pocket medical expenses deductible (over 65)

• Lower tax rates (higher rebates)
