We have answers to the most popular questions from our customers. If you can't find an answer to your question, please contact us.

How long does it take to get an utr number?

Its a 10-digit number. It might just be called tax reference. Youll get your UTR by post 15 days after you register.

What is a CWF1 form?

The CWF1 (Construction Workers Form 1) is the official form used to register with HMRC as a self-employed individual (sometimes called a sole trader). By submitting this form, youre essentially informing HMRC that youre responsible for paying your own taxes and National Insurance contributions.

What is a disadvantage of a sole trader?

As a sole trader, the business owner and company are one and the same for legal purposes. So, you are liable for all company debts. The proprietor bears any liabilities or obligations owed by the business, so theres an increased risk that it will impact your personal finances and assets if the company fails.

What is the difference between CWF1 and SA1?

Whats the difference between a CWF1 Form and a SA1 Form? Submitting a SA1 Form signs you up for Self Assessment, but there are lots of different reasons why you might need to register. A CWF1 Form confirms to HMRC that youre setting up your own business.

Whats an advantage of being a sole trader?

One of the biggest advantages of being a sole trader is simplicity. Because there is no distinction between you as a sole trader and your business, there are fewer legal and financial requirements to meet. This makes it easier to get started and run a business on a smaller scale.

Is a sole proprietor the same as self-employed?

Since a sole proprietor operates a business on its own, they are considered self-employed. A self-employed individual simply means the person works for him or herself. Its just a business term. A sole proprietor refers to someone who owns a business by themselves.

Whats the difference between a sole trader and self-employed?

To summarise, the main difference between sole trader and self employed is that sole trader describes your business structure; self-employed means that you are not employed by somebody else or that you pay tax through PAYE.

Is self-employed the same as sole trader?

Sole trader describes your business structure, while self-employed is a way of saying that you dont work for an employer or pay tax through PAYE. Both terms are often used interchangeably: if youre self-employed then youre basically running a sole trader business.
