Second Job W-2 Help- What To Claim? (increase, income, deduction)

[lowkeystatus]

I'm currently working a full-time job- Single, claiming 1 exemption on my W-2. I am getting ready to start a second part-time job and would like to know how many exemptions to claim on my W-2 so as not to get screwed at tax time. A few years ago, I worked two jobs and claimed 1 exemption for each W-2 and wound up owing a lot at tax time. Really would like to avoid that this time around. Any advice would be appreciated.

I claim 0 all the time. Even if I have a full time job, I claim 0. This way I never owe, and get money back. I currently have two part-time jobs, and claim 0 on both of them. It doesn't matter how many jobs I have, I'll claim 0 on all of them.

Why not just take your last single job income add the estimated increase and go from there on your last tax return. That way you can get a idea o the increase tax liabilty liely. Then you can actually claim a dollar amount on your W-2 if you wish to add extra then standard deduction.Or you can use IRS for at their site to figure the best dedcution filing status for your total income.

Thank you for the replies.

I started my full-time job in March, so I am not sure what my actual income will be during tax time. I will try to check out the IRS website and see if I can figure something out.
