How to Use Tax Refund Estimator (2026) - Complete Guide

Estimating your potential tax refund before filing your tax return helps you plan your finances and understand what to expect from SARS. Our free Tax Refund Estimator helps you calculate potential refunds based on your income, PAYE paid, deductions, and tax credits. This comprehensive guide explains how to use the estimator effectively and provides detailed information about tax refund calculations in 2026.

Understanding Tax Refunds

A tax refund occurs when you've paid more tax during the year (through PAYE) than your actual tax liability. SARS refunds the difference after you file your tax return.

Components of Tax Refund Calculation

Annual Income: Your total taxable income for the tax year
PAYE Paid: Tax deducted from your salary during the year
Deductions: Expenses that reduce your taxable income
Tax Credits: Amounts that reduce your tax liability
Tax Liability: Your actual tax owed based on income and deductions
