Input VAT vs Output VAT — sounds like the title of a very boring boxing match, right? Luckily, it’s not nearly as scary as it seems. Understanding the difference can save your business money, keep SARS happy, and possibly reduce your coffee intake during tax season.

⚖️ Input VAT vs Output VAT — Explained Like You’re Five (But With Business Words)

Here’s the short version:

  • 💳 Input VAT → The VAT you pay on business purchases. Think of it as “VAT you can claim back.”

  • 💰 Output VAT → The VAT you charge customers when you sell stuff. This is “VAT you hand over to SARS.”

If Input VAT is the good friend who gives you money back, Output VAT is the friend who borrows money and reminds you to pay your taxes on time.

The balance between them decides whether:

  • You get a refund from SARS (yay 🎉)

  • Or you owe SARS money (less yay 😅)

📅 How far back can you claim input VAT in South Africa?

Here’s the magic number: 5 years.
That’s how far back SARS lets you claim input VAT — as long as you have:

  • ✅ A valid tax invoice

  • ✅ Proof it’s a legitimate business expense

  • ✅ Not already claimed it in another VAT return

Pro tip: The sooner you claim, the less chance you’ll have to dig through old files, dusty boxes, and that mysterious “random paperwork” drawer in your office.

🕰 Is backdating VAT claims legal?

Yes — as long as you play by the rules.
You can backdate VAT claims within the five-year window, provided you:

  • Keep your paperwork squeaky clean

  • Only claim on qualifying expenses

  • Don’t try anything creative that SARS might not find funny

Remember: SARS has a very good sense for sniffing out dodgy claims — and they don’t bring cupcakes when they visit.

✅ Final VAT Wisdom

Think of VAT as a boomerang:

  • Output VAT → You throw it to SARS

  • Input VAT → It comes back to you (if you threw it right)

Stay organized, file on time, and keep your invoices neat — your future self will thank you when VAT season rolls around.
