Travel expenses are tax-deductible if they are ordinary, necessary, and incurred while traveling away from your tax home for business. Deductible expenses include transportation, lodging, and 50% of business meals. To qualify, you must be away longer than a standard workday and require sleep or rest.
Deductible travel expenses include:
Travel by airplane, train, bus or car between your home and your business destination. Fares for taxis or other types of transportation between an airport or train station and a hotel, or from a hotel to a work location.
IRS travel reimbursement guidelines require expenses to be "ordinary and necessary," not lavish, with proper documentation (receipts for $75+, amount, date, location, business purpose), submitted timely (within 60 days for "safe harbor"), and often use standard rates (like 72.5 cents/mile for business in 2026) for simplicity, covering transportation, lodging, meals (50% limit), and incidentals for temporary assignments away from home.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
Itemized receipts are always required for airfare, lodging, car rental, registration fees, and other expenses over $75. Itemized receipts should be original and show the name of the payee, the amount of the charge, the transaction date, and method of payment.
72.5 cents per mile driven for business use, up 2.5 cents from 2025. 20.5 cents per mile driven for medical purposes, down a half cent from 2025.
The IRS allows taxpayers to deduct up to $3,000 of realized investment losses ($1,500 if married filing separately) against ordinary income each year. This deduction applies only to losses in taxable investment accounts and must be realized by December 31st to count for that tax year.
Allowable expenses include your basic office costs such as stationery and the bills you pay on your business phone. Travel costs and staff salaries are also included, as is the cost of a uniform or other appropriate clothing (for example, if you work in a skilled or manual trade).
The section 179 deduction allows taxpayers, other than trusts and estates, to elect to expense a specified amount of the cost of qualifying property purchased for use in a business. For tax years beginning in 2026 the maximum deduction is $2,560,000, (2025, the maximum deduction is $2,500,000).
Claiming fuel costs without receipts
With this method, you can claim for up to 5,000 km of work-related trips without receipts for the financial year (the rate for 2025-26 is 88c per km). The other way to claim fuel for work-related trips is through the logbook method, which does require you to keep receipts.
Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
A travel allowance is compensation paid by an employer to employees to cover expenses incurred when travelling for business. In addition to lodging and transportation, travel allowances are typically used for airfare, meals, and other expenses related to business travel.
Tracking actual car and truck expenses requires detailed record-keeping. You must keep track of all expenses and receipts related to your car, in addition to the number of business miles driven.
Here's a general overview of the types of travel expenses you can write off:
And as well as an invoice or receipt for a travel cost, you should retain tickets for an event or meeting notes, because this can help to prove the legitimacy of your expense claim. A common mistake when it comes to business travel is to forget to ask for a receipt for taxi journeys, but it's one you need to avoid.
The IRS uses a combination of automated and human processes to select which tax returns to audit. Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit.
