1) they will only look at your current income if it is more than 25% different to the figure provided by HMRC. HMRC’s figure will be your gross taxable earnings for a complete tax year, so before deduction of tax and NI but after deduction of any gross occupational pension contributions. If you’re employer operates a net occupational pension scheme, where your pension provider then claims tax relief back into your pension pot, or you pay into a private pension, you will need to get them to adjust the figure provided by HMRC to take account of those pension contributions for the relevant tax year. The HMRC figure will be made up of all taxable earnings, so basic pay, bonuses, commission, overtime and any taxable allowances you received. It will also include any taxable benefits from your employment, as normally shown on a P11D.
2) Only if it’s an adjustment to your gross taxable pay. If it’s a net recovery, then no.
3) It doesn’t matter who applies. If you and your ex don’t agree about the level of shared care that’s expected to happen, they’ll ask you both to provide evidence of any court order or written agreement that states what the pattern of care is expected to be. If no such evidence exists, the law says they should then see if there is any agreement between you about the pattern of care for the previous 12 months. If you still don’t both agree, then they can either make a decision on the balance of probabilities as to what the level of shared care is, or if the relevant criteria apply, they can put an assumption of shared care in place.
