There are pros and cons of being a limited company.
If you expect the company to make enough profit to take you into the higher rate tax band, then being a limited company can be more tax efficient (classic accountant speak!) although not necessarily. If your personal income goes above the higher rate threshold then you still pay higher rate tax.
You also pay less national insurance if you are an employee of the limited company, as long add your salary is less than the NI threshold (just under £8k). You pay yourself more by taking dividends from the taxed profit.
So you might give a bit less money to hmrc but you have to submit your accounts to companies house in a certain format. Not rocket science but something that needs to be done correctly and it’s a bit of a minefield, and one more thing to think about if you’re busy running a business! To pay an accountant to do it will cost maybe £1k. Therefore if you are a small company there is unlikely to be a financial benefit.
Whether you benefit from any kudos or reduced personal risk from being Ltd depends on the industry you’re in I guess, but it’s another factor to consider. I think most lenders or suppliers would still ask you to be personally liable for any debt, unless you have some trading history.
This is just my understanding which I’m still learning, hope I haven’t given you a bum steer. Definitely worth speaking to an accountant anyway.
