SYONYK - that is cool! Do you do the home office deduction for your business taxes? Do you file the Schedule C?
Structuring for deductions is, as far as I understand it, thinking through your anticipated expenses, and setting up your business structure so that you can deduct them as business expenses. One of the things I'm thinking of for us, is health insurance premiums. At this point, we pay for husband's health insurance premiums out of pocket, not pre-tax. Next year we may be paying for the entire family (6 of us) out of pocket. If he we had a home-based business, he could deduct the monthly premiums as a business expense (I think). So that might be a big difference for us. Another "structuring" would be including both of us as owners on the home-based business, and ensuring that if we go out to dinner or travel, we are talking and conducting business, so it's tax-deductible expense. Etc. Another structuring would be, if you drive a vehicle, to route your business errands in such a way that you can accomplish personal errands en-route, and claim mileage deduction for the trip as a business expense. Stuff like that.
In the circles I've run in (non-mustachian, not very financially literate, I'll admit!) this has all been very common thinking. On the boards here, it seems to be considered more towards the unethical side. That's why I'm trying to get a feel for what the other small-business folks here are doing. Seeing if these are overall bad ideas, coming from my broke friends, LOL, or if they're still good ideas, just underutilized or not known of by the MMM-salaried crowd. :-)
