The first tax season we were separated (it was the beginning of May so it was 6+ months too), I did our taxes a bunch of different ways and told him that I'd file them the most advantageous way and we'd split any refunds. IIRC, I had him claim our son so he wouldn't owe but I claimed head of household and got some back too. After that year I continued to file HoH (we alternated years claiming our son) but whatever refund I got, I kept.
