Contractors who are paid weekly, bi-weekly or every four weeks and whose final payday for the 2018/19 tax year falls on the 5th of April 2019 may be affected by the week 53 payment.
The 2019/20 tax year began on Saturday, 6th April 2019. There are some changes you should be aware of as a contractor (some of which came into effect on 1st April) as you may be affected.
Some contractors that are employed through agencies and umbrella companies are signing up to arrangements that claim to maximise their take-home pay and retain up to 90% of their income after tax and NI. But these are clearly tax avoidance schemes.
