My wife and I both have "0" for allowances on our W4s. She tends to make about 2/3 more than I do annually after bonuses. Every year when I enter her W2 information, we start out with a refund, but when I enter my W2, we end up owing a good amount.
If we are trying to either owe as little as possible each year (or get a refund), do I need to have additional taxes withheld on my W4 and if so, what is the best way to go about figuring out how much that is?
