As Ian G has said you can only pay dividends if the ltd company is making a profit.
Some total c##p is spoken on here. If you make a profit in any business you pay tax on those profits.
Its also true that your accountant wont be liable for any wrong doings, its down to you. With accontants, from my own experience the cheaper ones are best avoided, its like anything in life, you only get what you pay for.
Cash is king as it always has been and always will be, but its very wise to have other legitimate income that you have paid your taxes on to pay the bills. If not its only a matter of time before it comes back and bites you on the a##e.
A friends, friend had a business not turning over enough to be vat registered, he had a £90k car, his wife had a £50k car they lived in a £600k house, nice holidays twice a year, private schools for the two kids, all paid for from a company making just £15k profit pa
in the end he lost everything including his wife.
Mike, of course certain things can be paid for by your ltd company just as they can with sole trader or a partnership, but general everyday living expenses cant. If you dont have a wife who has a good income to pay the bills, how can you live?
Ltd is safer especially if you employ staff, but remember all assets are the companys and not yours, so that shiney new van and truckmount will be sold for peanuts at auction if the business fails.
