We got the Parental Tax Credit and DH earns quite a high salary its $1200 paid outover eight weeks. b The Acc supplement shouldn't affect it. Your best bet is to give the IRD a call.
Re your DP's leave. Its unpaid but if his boss is nice and he has AL owing he may be able to use that.
Def make sure you ring them straight away, Ds was born on a Thursday night and I calle dthem Friday, Thursday is their cutoff so we had to wait an extra two weeks
