Hypothetical:
Part time job flying a Garmin 430 equipped bird.
Could I legally write off a Garmin 430 in my own aircraft to maintain proficiency?
Anyone?
I'm not a CPA, you'd have to get a qualified answer from a qualified tax accountant.
I understand that you're flying someone else's airplane for work and want to put a 430 in your airplane and then fly it to maintain proficiency. I think the answer might be yes, you could take a deduction on it, but it's a heavily qualified yes. In other areas where there is a shared private/business usage, you have to track usage time for each and then divide the time out. That is further qualified that only the time you spend specifically flying for proficiency could be counted. Your $100 hamburger could not be counted because you had a private reason for performing the trip, you'd pretty much have to do nothing but proficiency for the purpose of work. That's a high bar to prove and if the IRS later disagrees with you, at a minimum you're liable for the fines or potentially jail time.
On the plus side, you could take the deduction on not just your 430, but your entire airplane. You'd probably have to cost the 430 into the cost of the airplane, then add hours to determine how much of the airplane is used for work vs pleasure and divide the depreciation cost between the two. Negative when you sell the airplane, you be liable for recapturing the cost of that depreciation and having to pay taxes on it, potentially to the tune of tens of thousands of dollars.
All this is incredibly difficult to compute and write up and I suspect you'd spend more in prep fees that you'd ever save from tax deductions.
Example numbers -
You airplane is worth 75,000 today. You add a 430 to it and estimate it is now worth 79,000. You set up a 20 year depreciation schedule and depreciate it at 3,950/year. Each year for 5 years you fly 10% heavily documented time of proficiency for your work. You can take 10% of 3,950 or 395 as a deduction. This will save you in the neighborhood of $120 in taxes each year for 5 years. It probably costs you $100 each year to file these taxes and you still have liability if you sell the airplane before the depreciation is up.
If you wanted to just take depreciation on the 430, the process is similar but you definitely won't recoup the cost of filing. The annual depreciation value of a 430 after splitting between business/pleasure and then the (presumed 35%) tax rate, you're not getting that much each year.
Again - I'm guessing, but I
think this is the basic idea of how it works.
You cannot run a business as a hobby and take tax deductions. Even if you make some token effort to call it a business, it won't work.
Actually you can. But it has to be a legitimate business, not a hobby that you call a business.
