a) Calculate the approximate income tax payable by a single man earning
￡85,000 p.a. who receives ￡7,000 p.a. net profit from renting out the
basement in his house, and who makes pension contributions of
￡10,000 p.a. He has an assessed company car benefit of ￡2,000 p.a.
He pays ￡1,000 p.a. for private health insurance and ￡8,000 p.a. for
private school fees for his son aged 14. He also inherited ￡23,000 in
this tax year from the estate of a relative.

b) What other tax on earnings would he have to pay and approximately
how much?

c) If he had received gross ￡3,000 interest from a deposit account from
which ￡600 has been deducted at source as tax, resulting in a net
￡2400 received, is there any further tax payable by him, and if so how
much?

d) For the rental of his basement he receives a gross rent of ￡12,000 p.a.
Describe the costs which he could be charging to reduce it to ￡7,000
net, and estimate their value.
