I usually owe the feds and get back roughly the same amount from the state. Not sure why that is or how I can fix it but I've learned to live with it. This year, since I took some long-term capital gains in December that haven't had any taxes withheld I will undoubtedly owe on both. But that's fine. Since I've taken more gains this year I should probably file an estimated advance tax payment or whatever that's called. Otherwise I'll probably get a penalty for underwithholding next year.
