Inform HMRC to strike off the company

Dears, I started a company a year ago, and now I applied to strike off my company. I want to ask about the following please: 1. What is the email address to post the DS01 form, or to inform I applied for strike off? 2. Since the company started I made only 3 sales transactions with total amount of almost $100. I am unable to provide the invoices because my Shopify store account was deleted and replaced by a new one that hadn't made any sales. What do I need to do? Thank you Regards

Hi Tarek,
You will need to contact Companies House in regards to striking off and complete DS01 form.
If the Company has traded, you will need to file a Tax return with HMRC for the account period trading took place. 
Thank you.
