Our son started daycare in February. We had been wrongly assuming that we could apply for childcare allowance (kinderopvangtoeslag) at the end of the year, with the tax returns. When we found out this was not the case, we ended up applying for it in August. However, it seems you can only apply for the allowance for the last 3 months. So, we lost 3 months of allowance. Considering the cost of our daycare, this is a significant amount.
Is there a way for recovering the 3 months of lost allowance or at least a part of it?
