Yes, the tax system is ridiculously complex in this country and full of daft s***. Want to know about unfairness in the tax system?
My wife and I are not entitled to child benefit, because my taxable income is over the £80,000 a year threshold. This is a lot down to the fact that I have a company car. HMRC tax company cars by requiring the employer to put the full list price of the vehicle in the P11D and deduct BIK on that figure annually, even though the car scheme provider never paid the list price in a million years and I am not being given £40,000 worth of benefits a year, my employer is leasing the vehicle from the car scheme provider over a 3 year lease and deducting it from my car allowance monthly.
Our friends receive full child benefit despite earning more as a household than my wife and I because both of them have decent jobs, but both get paid below the £60,000 a year threshold after which HMRC starting clawing it off you.
So because at some point the government wanted to "tax the rich" and clobber company cars (because only rich people get given company cars) you've got a situation where a couple that are richer than my wife and I receive over £2,000 a year from the government to help with childcare and Mt wife and I receive diddly squat.
And I'll tell you why successive governments have made our tax system so ridiculous and complex, it's so they can get away with the lies our current government did: "we're not raising taxes on working people, we are just going to raise a load of other taxes you oiks don't understand that will make you all poorer, so vote for us!"
