New limited company first year tax returns due. Have I got it right?

Hello,

Thanks for your time.

Last March I started a company and the company accounts year ends on the 3rd of March. I just want to run by you what I've gathered so far about tax implications for Limited Companies to see if I'm barking up the right tree :)

I'm all up for getting an accountant to do the actual end of year returns but I want to understand my company accounts too!

So based on an example total turnover of £50,000;

Total turnover: £50,000

Expenses: £15,000
Salaries (myself and my wife at £442 per week): £10,608
Total expenses: £25,608

Total pre-tax profit: £24,392
Total corporation tax due (20%): £4,878.40

Profit available for dividends: £19,513.60

Questions;

• Does this look correct?
• I only have to fill in a Limited Company tax return? Or are there more forms?
• Paying ourselves this salary which is the NI threshold, the company doesn't have to pay tax on the salaries?
• My wife and I, we don't have to pay tax on these salaries either?
• I'm able to then give the remaining amount (or a part thereof) to myself as dividends. The company doesn't pay tax on dividends. Do I have to pay tax on those dividends?
• Finally, do we have to fill in a standard self assessment? Or not because we are seen as an employee of the company and the salary is below the NI threshold?

Thanks for your time!
