Please choose the correct ending to complete the given sentence: Travel: [header] How to claim travel expenses [title] Save all receipts on business trips. [step] When you travel for work, nearly all of your expenses while you're on the road are fully or partially deductible on your taxes. To qualify as a deduction, the expenses must simply be necessary for you to conduct business.

Ending1: In other words, just take the expenses that are no longer relevant to your life and deduct them from your taxes. [substeps] Check on the list of deductible goals you set for yourself each time you travel. Ending2: [substeps] It's usually easier to just save receipts for everything. You can sit down later and analyze exactly which expenses are deductible. Ending3: Check your tax returns for the past year or more to see how much of your expenses actually contain income you already own. [substeps] Check online for a file that holds and records any deductions you incurred while traveling. Ending4: [substeps] You can deduct these expenses out of your gross income by saving the rest of your wages. These amounts will not automatically lower your deductible, and there's no need to deduct the rental car deduction.
