overpayment of CM

My ex is self employed and having just collated his accounts for 14-15 has concluded that he has been over paying me for 14-15 and wants to adjust the payments for the coming year.

This seems a bit back to front to me. I thought 14-15 accounts would be used to calculate his payments due for 15-16??

How does this all work please for self employed parents, I cannot see anything online to help me.

Many Thanks

Think the cm use last years p60 to work out the current years child maintenance and so does child credits.

Would you prefer to pay back the overpayment and start a fresh?

What was your original agreement?

If you were using CSA then the assessment going forwards would be based on the accounts he has now, so yes it would go down.

Equally the tax credit system uses an estimate for your income for the year being paid then adjusts it when the final year end figures are known.

Is there any sort of order in place or is it a private agreement?

Have you agreed payment would run from Jan 1st to Jan 1st or from April to April?

Consent Order was in place for a higher amount and then when daughter turned 18 it changed to:

''payments to reduce inline with CSA rules'' for remaining child''. He adjusted the monthly payment figure using the online calculator tool.

I understand it going down for the new year now based on 14-15 accounts but he is saying he has overpaid me from end of last year until now so basically I owe him money back which he will deduct from what is due for this year... if that makes sense?

Basically he has underpaid me on Spousal maintenance and he now sees that if he has overpaid on CM we are probably about straight. However I am not sure it would like that with CM.

Sorry I do not understand what you mean Mrs Mathsisfun about starting afresh.

What I meant what your ex is saying.

What you need to decide is when the ''year'' runs either Jan to Jan or April to April

It doesn''t seem unreasonable to say I owe you sm but as I have been overpaying you cm and the amounts are similar we are even
