help me to calculate the maintenance!!

I am really struggling. Gross £52, bonus £12, the work pay for private insurance / dental insurance / life insurance / death in service insurance / accident insurane / income support insurance - £6 in total. CSA is saying that £6 is a benefit in kind and I have to pay 15% on after tax from £6, BUT I am not getting it as cash. Is it fair?

This does seem unfair. I''m imagining that if you opted out of this work system then you wouldn''t get a cash equivalent so I don''t understand why it is being taken into consideration. I would challenge this as the csa change their tune depending on who you speak to.

CSA normally excludes benefits in kind from income so this should not be included.
www.childsupportsolutions.co.uk/lecturenotes.htm see the section on employed earners

When was the case opened with the CSA? If it was before March 2003 it would be under the old rules and benefits in kind are included as income if I remember correctly.

With CSA2 benefits in kind may be included when there is a variation to the standard assessment if the benefit is deemed to be a way of avoiding paying child support. But under CSA2 with an income of less than £100 child maintenance is paid at the flat rate of £5 per week rather than the basic rate of 15%.???

Im assuming they are talking gross £52000 and not £52

My typical payslip:

Tax Code 740L
Reference Salary 4333.33
Flex Allowance 457.99

Deductions:
PAYE 1052.76

NI A 368.06

Dental Insurance* 38.45 - this is my voluntarily expense from my Flex
Allowance, I would get it as taxable income otherwise

Dependants Death In Service 35.7 - this is NOT a voluntarily expense from my Flex Allowance, I cannot get this as cash and I cannot cancel

Group Income Protection 21.8 - this is NOT a voluntarily expense from my Flex Allowance, I cannot get this as cash and I cannot cancel

Group Life Assurance Employee 11.09

Group Personal Pension NI ERS Recoup 41.86 - I am not sure what it is,I can use a part of my Flex Allowance to contribute to a pension, but I do not do and prefer to have a taxable income instead

Personal Accident Insurance* 6.08 - this is my voluntarily expense from my Flex Allowance, I would get it as taxable income otherwise

Private Medical Insurance* 129.1 - I pay for me and for my daughter, my part cannot be received as cash and I cannot cancel it, but my daughter''s part can be received as taxable income otherwise, BUT I prefer to keep PMI for her (I do not factor it in child support at all)

Taxable Pay 4680.87
Non Taxable Pay 110.45
Gross Pay 4791.32
PAYE 1052.76
NI Employees 368.06
NI Employers 535.88

At this moment, I am paying 500 per month of child support. Fair?

* Taxable benefit

By my calculations you have just over £3,000 a month left in your pay packet after all deductions. I think the difference between what you have been assessed at and what you think you should be assessed (i.e. 15% after tax and NI v. 15% after tax, NI and the various benefits) is only about £40 a month. Is that right?
