I'd like to think I'm a somewhat intelligent fellow. Yet I've been blindsided once again by a notice from the state tax people that my tax return was wrong. They say I calculated too large a tax liability. This is the third or fourth time this has happened to me. I always triple-check everything before I send it out, and always check everything again after they send their notice back. The only possible explanation is that the tax tables published in the instruction manuals are not the actual tax tables I should be using. I never have this trouble with the federal return. Or at least they've never told me.
