Summer means travel... be careful with business travel myths:
1. If I do any work on the trip, the whole thing is deductible. Not quite, the IRS looks at your primary purpose. Transportation costs are fully deductible only if you spent more time on business than personal activities. Lodging and meals still get split day by day regardless. Miscount days and a fully deductible trip becomes partially deductible.
2. My spouse or kids can come along and its all deductible because we're a 'family business'. YOUR travel costs are deductible, theirs generally are not. If your spouse genuinely works in the business, keep records of what they actually did on the trip.
3. A receipt is all the documentation I need. A receipt tells what you bought, not why. IRS requires records of the amount, time and place, business purpose and who you met with. Keep a simple log: date, destination, who, why.
4. Conferences and conventions are automatically deductible in full. They are deductible only if conference is directly related to your trade or business and even them, only the business portion. Tack on a few vacation days and those days' lodging and meals come out of the deduction.
The deduction isn't wrong because you traveled and did some work. It's wrong when the paperwork can't back up the business purpose or when paperwork contradicts itself.
