Any idea which option would be best for us? I'm totally confused to be honest. In case it helps we both earn roughly the same - 34K per year.
Lorz said:The main benefit is if one of you pays 20% tax and the other 42%. By combining your allowances and credits you could end up paying 20% on all earnings. ie if wife earns €20k (20%) and you earn €40k (20% & 42%). In this scenario your wife would have about €12k of her allowance left. By combining your allowances rather than you both having €32k allowance each and your wife not using all of hers you could combine your earnings and allowances and so you would earn up to €64k and pay tax at 20% on the entire income!
