<prompt> Human: Hi Reddit Im 18 years old and new at dealing with taxes. First time also using TurboTax. In 2017 I worked 3 seprate jobs and received 4 W-2s one job requires me to work at 2 seprate stores I made about 10,000. While entering my first 2 forms into TurboTax all is well, I cant complain about over 500 but after entering the last form it dropped down to under 300? I double checked that I entered everything correctly I should mention I also went to school for half the year of 2017. For some reason this just doesnt seem right to me, last year I made less and received more from my tax return, am I making a mistake?  <response>: Read my long explanation for why tax software misleads you if you think the refund numbers you see as you enter W-2s mean anything practical. Its only the number after youve entered all your incomes and all your withholding amounts that is valid. Sorry you got tricked into thinking all was well. In reality you overpaid but just by a little bit. And it wasnt necessarily just the last jobs fault.Its easy for this to happen when you have multiple jobs, and to counter it, the suggestion is often to use a lower allowances number on some of your W-4s. In fact, page 2 of the Form W-4 has a worksheet called Multiple Jobs worksheet for this purpose. Even better as a resource is the online tool, which lets you enter jobs of various lengths during the year. It gives you suggestions of how to set your W-4s so by end of year you will have paid in the right amount. Its down for revision currently, but try it some time when its back up.P.S. Having a refund of only 300 is pretty good. It means your payments of tax were not too much more than your actual tax. It might not be necessary to do anything different than you have been doing. But its good to use the above-mentioned tool from time to time to check to make sure you arent under-paying.
