The difficulty is that contractors are taxed on 'profit' (and potentially at different rates to employees), whereas employees are taxed on income. Thefore, the only really comparable way is annual income after tax with costs to carry out services deducted, compared to annual income after tax with costs to carry out employment deducted.[TW]Fox;18190394 said:Average yearly income before tax but after expenses deducted perhaps? It's difficult isn't it because contracting income is obviously higher but then so are costs and, critically, there will be times when a contractor has no work.
