Don't forget to double check how much money is being withheld from your paychecks currently. Especially if you haven't reviewed this recently. If too much is being withheld, you are missing out on having that money available to you now. If too little is being withheld, you could be surprised at tax season with an unexpected and very unpleasant need to pay Uncle Sam for the difference.
Contact your tax professional who can review your current status and give you a good idea of where you are and whether your withholdings are appropriate given your circumstances. FlemmerAssociates can assist with this if you are looking for a new CPA. 916-576-7000.
