My job is a mile from my home. I keep a mileage log. I also keep a car log for gasoline fill ups and other repairs, so I have a dual record. My commuting miles to work are deducted from my total as I also do a fair amount of travel for my job. Sometimes I have business in the town I am officiating in, so I use that for business rather tahn officiating. I think I ended up netting $250 this year as taxable income. My previous two years, I was in the hole.

Principal Business Code?
 

What would be my principal business code?

Good question. Maybe someone here might have some better ideas but from the lists I have these might be good choices:

561900 - Other support services
711210 - Spectator sports
711510 - Independent Artists, Writers and Performers
611000 - Educational services
999999 - Unable to Classify

I think the service just uses the business codes to compile data. While putting a code in is required (I think), there is no requirement that you put the exact code that they would want to see (that I'm aware of). I've NEVER had an IRS auditor even mention the business code I used, much less questioned whether or not it was "correct".
