Sorry but you are wrong about the VAT. If he was an employee the company would still have to collect VAT. Even if he was a sole trader with turnover above £70k he would have to charge VAT.
Being a limited company is not in itself a way of avoiding tax, but paying yourself through dividends instead of a salary or even as a self employed contractor for the company is a way of avoiding tax.
I know because I do it too.
After many years as a sole trader my biggest customer decided it needed to put the work I do for it out to tender, and I only stood a chance of keeping the work as a limited company bidding for it. I got the contract. All of a sudden I needed an accountant having always done my own books - and he was very clear:
Option 1 was to be an employee - the company pays employers' NI; I pay income tax and NI through PAYE; extra admin costs of running a payroll.
Option 2 was to be a self employed contractor to the company to avoid employers' NI and admin costs - but I would be in breach of IR35.
Option 3 was to pay myself through dividends. This is least admin and most 'tax efficient' - i.e. I pay least tax.
Now for me, the amount of tax I am saving is probably no more than £4-5k per year and a good chunk of that goes to the accountant.
I am hoping the company will grow - at the moment it is just me and a few others, the others just do small chunks of work on a self employed basis. If it does grows and I am not a one man band any more it will be much better for the company to pay us all a salary.
I feel a little bit guilty, but not very guilty. The money I take out of the business is, after my reduced tax bill, is about equivalent to someone getting £70-80k in a salary. To me that is a good salary but I work very hard for it.
So although this is a form of tax avoidance I don't think it is a terrible thing to do - and the HMRC is very aware of it and also doesn't worry too much about it.
However
I do think it is wrong that, as in the original link, someone takes £150k in this case, no doubt much more when it comes to Paxman / Marr others - and even though they are working exclusively for one corporation, and a publicly funded one at that, they channel the money through a limited company to avoid tax. Yes they miss out on redundancy / maternity rights but they can easily afford to save for such eventuality. The BBC is avoiding NI payments and they are avoiding tax and NI and I think cases like this go across the greyish fuzzy line between right and wrong.
Your DH and I may be near to that line or even somewhere in the middle of it but lets worry about the real villains here.
Of course the torygraph is only publishing this to have a go at the BBC - I think the BBC is wonderful but I think this practice should be stopped - all their people should be on PAYE and the overpaid ones should be allowed to go elsewhere if they want.
