<prompt> Human: My employer recently updated to a new payment system. I was looking through the different menus, and found my W-4. I realized that I never updated my W-4 when I got married in late 2016. Its currently set at single, with 1 exemption. After going through a 2017 W-4, it looks like it should be 0 exemptions, with an additional amount of 1220 per year withheld divided by the number of pay periods remaining.We are planning on filing jointly and my spouse works. Any idea how this will affect us? Also, when should I update my W-4? I noticed there is not a 2018 form yet. From a bit of reading online, it looks like this shouldnt affect us too much, and it would be best to wait until the new calculator is up. Does that sound correct?  <response>: No idea what these people are going on about but you should wait for the 2018 W-4 and then follow the instructions so that youre not floating the government an interest free loan. Whether that be 0, or 2, or 10 exemptions. Just follow the form and youll get pretty close to right. Its easy to miss the dual income household section so keep an eye out for that. You got this. :Edit: Yes, it sounds correct. :
