I too want clients to call before a tax situation arises so I don't have to pick them up off the floor in April when they do their return. How many clients have you had who took $100k out their 401k, had 10% withheld, and told you they had the taxes taken out? I like it when clients call to tell me they sold their home (main or vacation?), inherited something (makes a difference if it's a 401k, IRA, savings bonds), got divorced and are now paying/getting alimony. I can tell them how much to set aside for taxes, set them up with estimates if necessary, or tell them no problem. Makes me feel good that they thought to ask me.
Had a client query today about some weird profit interest warrants his company granted him. Glad he called now instead of during the busy season so I could do the research. We've also had some legitimate questions about employee health care reimbursements that I am still clueless about.
Then there are the high-maintenance clients. Today I did my FOURTH tax projection for one. God forbid he pay $100 too much for his 4th quarter estimate. Another has asked about 10 times about how much he could contribute to a solo 401k vs. a SEP, income changing as the year progressed. Another had a million questions over the past few months about renting out very expensive inherited property. Like Rita, we just keep raising the fees. Maybe they're at the point where they feel free to pick up the phone and call us anytime because we charge them so much.
I was at a seminar last week where the speaker was an attorney who helped people with foreign tax issues and big IRS debts (not a pennies on the dollar guy). When people called he would tell them if their case was easy enough to handle on their own or they should come in to see him. To those who asked if the initial consultation was free, he told them they just had it.
