To open a business bank account in South Africa you need your company registration documents (CoR14.3), certified IDs for every director and anyone with signing authority, proof of business address, proof of residential address for each director, and your SARS tax reference number. Most banks turn it around in 3 to 10 working days once the pack is complete.
The application itself is simple. What delays it is FICA — the bank must verify identity and address for every person connected to the account, and one missing utility bill stops the whole thing.
TL;DR
Core pack: CoR14.3 · certified director IDs · proof of business address · proof of each director's residential address · tax number
Proof of address generally must be under three months old
Sole proprietors can open business accounts too — ID plus proof of address plus proof of trading
Turnaround: 3–10 working days
Bring everyone with signing authority, not just the main director
The document checklist
For a company or close corporation
| Document | Notes |
|---|---|
| CoR14.3 registration certificate | Or CK documents for a close corporation |
| Certified ID for every director and signatory | Usually not older than three months |
| Proof of business address | Lease, utility bill, or municipal account in the company's name |
| Proof of residential address for each director | Under three months old |
| SARS tax reference number | The company's income tax number |
| Resolution to open the account | Most banks provide the template |
| VAT registration certificate | If registered |
For a sole proprietor
Certified ID
Proof of residential address, under three months old
Proof of trading — invoices, a contract, or a trading name registration
SARS tax reference number
You do not need a company to open a business account. Every major South African bank offers business accounts to sole proprietors, and using one is worth doing from the day you start trading.
The proof of address problem
This is where most applications stall, and it has an easy fix.
The requirement: a document in the person's name, at the address given, dated within the last three months. Typically a municipal account, a bank statement from another institution, a lease, or an insurance policy schedule.
The common problem: the utility bill is in a landlord's or spouse's name, or you live somewhere the account is not in your name.
The solutions banks generally accept:
An affidavit from the person whose name is on the bill, confirming you live there, together with their proof of address and ID
A signed lease agreement
A letter from the body corporate or landlord
Sort this out before you go in. It is the single most common reason a business bank account application takes three weeks instead of three days.
Choosing an account
Four things matter more than the marketing.
1. Monthly fees. Business accounts range from roughly R80 to over R500 a month. Bundled accounts with a fixed fee are usually cheaper than pay-as-you-transact once you are doing meaningful volume.
2. Transaction costs. Per-EFT charges, cash deposit fees and card machine rates. A retail business handling cash pays very differently from a consultancy doing twenty EFTs a month.
3. Accounting software integration. A live bank feed into Xero or similar saves hours every month and materially reduces bookkeeping errors. Check the integration exists and works before choosing — this is worth more than a R50 fee difference.
4. Card payment facilities. If you take card payments, compare merchant rates. They vary considerably and are negotiable at volume.
Why a separate account is not optional
Even where you are a sole proprietor and not legally required to have one:
Your accounting fee drops. Untangling business transactions from a personal account is billed at professional rates. A separate account is the single cheapest thing you can do to reduce what you pay your accountant.
Deductions become claimable. Expenses buried in a personal account routinely get missed, and 27% or 31% of every missed expense is real money.
VAT becomes defensible. A SARS verification of a mixed account is a considerably worse experience than one of a clean business account.
The corporate veil holds. For a company, mixing personal and business money is one of the behaviours that undermines the separation between you and the entity.
You can actually see how the business is doing. A bank balance that includes your personal spending tells you nothing.
After the account is open
Set up the accounting software feed immediately, while you are in the mindset. Retro-fitting six months of transactions is far more work.
Move all business income and expenses across — subscriptions, insurance, suppliers, card machines.
Set up a second account for tax money. The VAT and PAYE you collect is not yours. Move it out on receipt and the payment funds itself. This one habit prevents most SARS payment crises in small businesses.
Update your CSD registration and supplier records with the new details if you are already registered.
Frequently asked questions
What do I need to open a business bank account in South Africa? Your company registration documents (CoR14.3), certified IDs for every director and signatory, proof of business address, proof of residential address for each director dated within the last three months, and your SARS tax reference number. Most banks also require a resolution to open the account.
Can a sole proprietor open a business bank account? Yes. Every major South African bank offers business accounts to sole proprietors. You need your ID, proof of residential address, proof that you are trading, and your tax reference number.
How long does it take to open a business bank account? Typically 3 to 10 working days once the document pack is complete. Delays are almost always caused by FICA verification, particularly proof of address.
What if my proof of address is not in my name? Banks generally accept an affidavit from the person whose name is on the account confirming you live there, together with their ID and proof of address. A signed lease or a letter from the landlord or body corporate usually works too.
Do I need a company to open a business bank account? No. Sole proprietors can open business accounts. Having a separate business account is worth doing from day one regardless of your structure, because it reduces your accounting fee and makes expenses claimable.
Which business bank account is best? It depends on your transaction profile. Compare monthly fees, per-transaction costs, whether it integrates with your accounting software, and card machine rates if you take card payments. The accounting integration is usually worth more than a small difference in monthly fee.
Set it up once, properly
Getting the account open is the easy part. Getting the bank feed into your accounting software, moving every business transaction across, and separating the tax money is what actually makes the account useful.
Smartbook helps clients open a business bank account free as part of getting set up, then connects the feed so bookkeeping runs from live data rather than statements you have to find.
