Ok great,thank you UK tax man for spoiling the fun as usual.If true,I'm not surprised,but as its from the daily mail it's questionable, they are an awful paper,I don't trust anything they say.All this is going to do is prompt people to register as a limited company,it costs £12 to do so and then you can take £5k tax free dividend and then pay corporation tax @13% on the rest rather than income tax,which is usually 20-40% dependent on your earnings.This should only catch out people who are actually maxing decent money on a side business as the first £11k of income here is fax free anyway.How the tax man is going to decide if what you are doing is a business is ill defined so that means our tax office will probably just send out letters to people to scare she sh*t out of them to try and prompt people to pay(low hanging fruit) and then only actively pursue the bigger ones worth fighting in the courts.The courts have the power to make an order to instruct your employer to remove payments along with your normal tax from your pay cheque before you receive your wages.
I don't know how things will work in the States in years to come but UK law doesn't set a precedent in the US system,it could give US lawmakers some ideas though if it works
