A W-4 is a very simple form to instruct your employer to withhold the proper tax. It's written in very plain English and is fairly easy to follow. I honestly do not know of a CPA that will do one of these. If you're having trouble and cannot find a tutorial you like on line see if you can schedule a probing meeting. It should take an accounting student about 10 minutes to walk you through. There is even a worksheet on the back.If you have mitigating factors such as complex investments, partnership income, lies or garnishments, talk to your CPA about those, and then ask their advice regarding the W4 in the context of those issues.
