I am trying to start up self employed so i am having to advertise

You'll need to pay Class 2 NI contributions, unless you get a small earnings exception.

You are paying £121 per month on your business, with no current earnings.

What other costs will there be and how will you pay for them? Do you need to buy materials for your business - if so will you want to arrange credit accounts with your suppliers, arrange a business loan from your bank or will you have the cash to pay up front?

How long does your business plan show it will take for you to make any profit from your business and how will plans work regarding cash flow? There is a phrase that you must apply to your plans: 'Turnover is vanity, profit is sanity but cash is reality'.

Hopefully you've done all this and your business plan works - but don't plunge into a new business without very careful research first to ensure you have a viable proposition.
