<prompt> Human: Always get good advice from here, thought Id share my mistake.In the last 2 years my wife and I have had good salary increases and got married. We had switched both of our withholdings to married 1. I Completed our taxes yesterday and we ended up owing the irs around an additional 10,000.I ran our numbers through the irs withholding calculator and it suggested us both being single 0 along with an additional amount each paycheck.I was able to cover the shortfall, but it was not a fun surprise. Just wanted to share my lesson, if your financiallife situation changes, always run the numbers before its time to pay the tax man. Withholding calculator:  <response>: Correct. I had this happen a few years back too. Your reminder is a good idea.
