Business Travelers can save a lot of dough just by keeping those itty-bitty slips of paper thrust at them all day.
Travel deductions really add up when calculating taxes - and all businesses need to watch the bottom line. Even businesses who are well-off can stay that way by paying attention to the "minor" details of deducting toll fares and parking fees. Whether the business is yours, or you travel on someone else's expense account, you are responsible for keeping all travel receipts.
Always consult a tax specialist on any tax matters and business travel deductions. Tax laws change yearly, and are complex enough to employ whole armies of tax professionals. Remember that ignorance is no excuse under the law when it comes to tax fraud, so do your own research and consult proper professionals. Also bookmark the IRS Guide to Business Expenses.
