Tax Deadlines You Need to Know for August 2025
Managing your tax obligations on time is crucial to keeping your business compliant and penalty-free. With several important deadlines falling in August, planning ahead will help ensure smooth submissions and payments.

Why August 2025 Tax Deadlines Matter
Late submissions or missed payments can attract interest, penalties, or even trigger audits. Staying on top of each tax date protects your business cash flow and ensures you remain in good standing with SARS. August is particularly busy, with multiple deadlines for PAYE, VAT, excise duty, and provisional tax.
07 August – PAYE Submissions and Payments
Employers must submit and pay Pay-As-You-Earn (PAYE) tax by this date. PAYE ensures employees’ income tax is collected and paid over to SARS monthly. Delays here can lead to stiff penalties and interest charges.
25 August – VAT Manual Submissions
VAT vendors using manual submissions must file and pay VAT by this date. Whether your business collects VAT on sales or claims input VAT on expenses, accurate reporting is essential to avoid errors that could raise red flags with SARS.

28 August – Excise Duty Payments
Excise duty applies to specific goods like alcohol, tobacco, and fuel. Businesses in these industries must make their payments on time. Excise duty compliance is closely monitored, and missed deadlines can quickly accumulate penalties.
29 August – VAT Electronic and Provisional Tax
The month ends with several major deadlines. VAT vendors who file electronically must submit and pay by 29 August. This date also applies to Corporate Income Tax provisional payments and Personal Income Tax provisional payments where applicable. These provisional tax payments are critical for businesses and individuals with irregular or variable income.
August is a heavy month for tax compliance. From PAYE at the start of the month to VAT and provisional tax at the end, missing a deadline could cost your business dearly. Mark these dates in your calendar and work with your accountant to ensure submissions are accurate, on time, and stress-free.
