If you are self-employed, it is not a legal requirement to have a business credit card, since you can make any purchases using your debit card or business current account.
However, having a business credit card can significantly save you time and effort by putting all your business expenses in one place, making it easier to submit your tax return to the HMRC and earn rewards too.

Manage your expenses more efficiently
A business will always incur costs and expenses, if you are self-employed, a freelancer or contractor. You will usually need to pay for your phone, computer, travel and any other tools that you might need for your business.
If you are using your personal account to make all your business expenses, this is perfectly viable, but can create a lot of work when submitting your tax return.
You need to find out what are your business expenses, since this will allow you to claim some tax reductions and also work out your overall profit for the year.
However, if you are using your personal account, you risk mixing everything up with your day-to-day living expenses and it can be quite a hassle sorting this out and getting it right for you tax return.
But having a separate business credit for all your expenses can be an efficient way to keep everything separate and you will just need to use your bank statements or download a report to get all your expenses together.
What things can I put on my business credit card?
Any business expenses can be put on a credit card including:

Not all retailers or providers will be able to accept business credit cards, but you can always draw down the money in cash, which is an option offered by Capital on Tap. Alternatively, you can pay using your business current account or by cheque.
