I have prepared many tax returns, including federal 1040. 1041 (Corporations, Trusts, and Partnerships) and at least 10 state returns, some manually because the software I was using didn't handle non-resident returns for those states.And..we just found the CPA who never prepared tax returns. If you seriously think it takes me more than 2 minutes to enter itemized deductions, you haven't prepared a tax return since 2017.
And if you think I spend ANY time looking at receipts and totaling them up, you haven't prepared a return since 2005 or earlier.
It doesn't take a long time to just enter itemized deductions if they are totaled, but if one is talking about medical expenses that includes mileage to and from doctors appointments, and all the other stuff I mentioned, it takes a lot more than 2 minutes. If you can get your client to do all the work totaling those things up for you, that's great, but I wonder why they would need someone to simply enter them into a tax return software program. My experience is that clients just hand over a bunch of receipts and expect the tax preparer to figure it out, which often requires follow-up to answer questions. Once you go down the road of itemizing deductions, then usually there are some things you have to ask the client about that they didn't think about, such as all their charitable donations (including cash), casualty losses, etc.
