CSA: bonus, flexible benefits, private insurance

1) I have flexible benefits from my work, one of them is an opportunity to buy 5 additional holidays, it rounds to almost a thousand £ pa. I bought five holidays, reduced my net income accordingly, but CSA still counted it as gross my income, is it fair? I have many other flexible benefits that are obligatory like: income protection insurance, death in service - pension for dependants, private medical insurance. I cannot cancel these benefits and take cash, but still CSA counts it as gross income. Is it fair?

2) I got a bonus in June 2010, we broke up in Dec 2010. We spent these money on holidays in summer/autumn, I was left with debts even. CSA pro rated this bonus and added to the required payment. Is it fair? This money has gone. They were earn and spent when we were together. Why did not they ask me then to pay all 6 months in arrears? I believe it is logical to pay from the income one receives straight after the divorce. If I receive the next bonus in June 2011, I will pay 15% from the net income in one go. I do not see the point of charging me for past incomes.

3) I am paying £400pa after tax for the private medical insurance for my child. Can this offset my CSA payments?

No ideas?

CSA work on what you earn so if you do overtime or take cash instead of holidays they will take that money into account.

annual bonuses are taken as being for the next 52 weeks and averaged out. This may not be fair but before they did that they were looking at the bonus being applicable to just that week or month so if that was one of the pay slips they assessed you on it waas a big problem.

Again only deductions they allow are tax, NI and pension.

If you are looking for fairness or good service with the interests of children at its centre the CSA is not the right place. Could you not come to a private agreement with your ex? Its a much better place to be for both of you.
