<prompt> Human: Some background:Last year, we made 133k. Total Fed taxes were 16.5k, not including SS and Medicare. Total NYS taxes were 7k, NY City taxes were 4k. Total itemized deductions were 14k. Two kids. I need to know:a other than not paying NYC taxes anymore, approximately how much TOTAL tax savings could I expect over the course of a year?b By what proportion should I reduce my federal and state withholdings by, starting now? In other words, for example, if I will have a total of 12k in taxes savings again, not including the fact that Ill no longer be paying NYC taxes, should I allocate it 5050 between Fed and State? 6040? Something else?Keep in mind Im only asking for a rough ROUGH estimate until I get to talk to my accountant next year to get more exact figures. I just need to increase my paycheck now, because I was counting on a significant decrease in withholdings and therefore bigger paycheck to be able to afford the monthly mortgage payments and other expenses.  <response>: I just need to increase my paycheck now, because I was counting on a significant decrease in withholdings and therefore bigger paycheck to be able to afford the monthly mortgage payments and other expenses.Yikes. If youre in need of bigger checks to afford your mortgage payment, I do hope you didnt buy too much house. Back of the envelope, based on 34k in taxes and interest says youve got a mortgage in the neighborhood of 560 - 600k?But that point aside, uForestman88 has the best idea -- just plug the interest tax numbers into last years return, and take out the NYC taxes. The rates havent changed significantly, and youll get a pretty close estimate of what next years tax situation would look like.
