Here's what I did in the UK.
1. Create company for £15 on government website
2. Get bank account in company name, applied online, took 20 minutes. I had card and everything within a week.
3. Enrol for tax on government website (optional in UK if your company turnover is less than £80k). Bit confusing, but accountant can help and only takes 1/2 hour at most
4. Start selling subs to my app, stripe integration
There are some admin tasks I have to do regularly:
1. Monthly, keep on top of accounts. I use an app, QuickBooks online. But I've previously used a spreadsheet for my consultancy company as there were only a handful of invoices and expenses each month
2. Every 3 months. Submit VAT returns and pay government tax. Takes 1/2 hour
5. File accounts yearly. Accountant will do this for £400 per year or you can do it yourself (half days work, but confusing)
6. File confirmation statement yearly (UK company thing, confirms who the shareholders are and the share composition). Costs £18, takes 10 mins
To break it down:
- Incorporate company
- Get bank account
- Register for taxes
- Make sure you do your admin
You might find you need to get certain things certified when providing ID, our Post Office does that. There's other little things I'm skipping over, like some people prefer not to use their home address and setup a virtual office, etc, but generally it's pretty simple.
