So, I've NC for his as I'm going to have to give info about my finances.
My DH gross salary is £43500. After salary sacrifice such as pension, child care vouchers etc he is taxed on £37000 so he pays 20% tax.
I work part time and earn £8000 annually so don't pay tax.
I've just applied for the marriage allowance as he is a lower bracket tax payer paying 20% but I'm now worried that because of the £43500 before benefits maybe I shouldn't have applied.
Anyone have any advice or experience of this? All I can find online is that if DH pays lower rate tax then we are eligible.
My DH says that if we aren't eligible then they'll refuse the application but I'm concerned that I ticked the box saying 'less than £43000' because the only pays tax on £37000 and I'll be told off for defrauding he government 
If this sounds really stupid and obvious to people the please be kind, I really can't work out what we're eligible for.
