Can I Write Off Lunch as a Business Expense: 50% Cap and Exceptions

You can write off lunch as a business expense when the meal has a real professional purpose, the cost isn’t extravagant, and you or an employee are at the table, but the deduction is capped at 50% of what you spend, including tax and tip. The sandwich you grab alone at your desk doesn’t count, no matter how busy the day is. What separates a deductible business lunch from a personal one comes down to who you’re eating with, what you’re discussing, and whether you’re traveling away from your regular workplace.

What Actually Qualifies

Federal tax law puts two hurdles in front of any meal deduction. The expense first has to be “ordinary and necessary” for your trade or business under IRC Section 162 — common and accepted in your line of work, and helpful and appropriate even if not strictly required.¹

IRC Section 274(k) then adds two rules specific to food and beverages: the cost can’t be lavish or extravagant under the circumstances, and you or your employee must be physically present when the food is provided.² “Lavish” isn’t tied to a fixed dollar amount. The IRS looks at whether the cost is reasonable given the situation, not whether you crossed a specific threshold.³

Pay for someone’s lunch but don’t attend? Generally not deductible. Eat lunch that has no connection to your business beyond the fact that you own one? That’s personal consumption.

When a Lunch Counts, and When It Doesn’t

Meals With Clients, Vendors, or Colleagues

Lunch with a current or prospective client where you discuss a deal, negotiate terms, or review a project is the textbook deductible meal. The same goes for meals with vendors, consultants, or professional associates when you’re talking about actual business. You need a real reason for the meal beyond socializing.

Meals While Traveling

When you travel away from your tax home on business and the trip requires you to stop for sleep or rest, your meals become deductible even if you eat alone.³ Your tax home is the general area of your main place of business, not necessarily where you live.⁴ A day trip to a nearby city where you don’t need overnight lodging won’t qualify.

Temporary assignments have their own wrinkle. Meals on an assignment realistically expected to last one year or less are deductible; an assignment expected to last longer than a year is treated as indefinite, which makes that location your new tax home and ends the travel meal deduction.³

Your Regular Lunch at the Office

This is where most people’s hopes end. The lunch you eat alone at your regular workplace is a personal expense. You’d eat lunch whether you had a business or not. The IRS draws a hard line here, and claiming these meals is one of the fastest ways to invite scrutiny.

Food at an Entertainment Event

Business entertainment — sporting events, concerts, golf outings — has been completely nondeductible since 2018.² Food purchased at an entertainment venue can still qualify for the 50% meal deduction, but only if the cost is stated separately from the entertainment on the bill. Take a client to a basketball game where the invoice breaks out food and tickets as separate line items, and 50% of the food portion is deductible. You cannot inflate the food charge to absorb the entertainment cost.⁵

W-2 Employees Are Mostly Locked Out

If you’re a salaried employee rather than a business owner or self-employed, the math almost certainly doesn’t work for you. The Tax Cuts and Jobs Act suspended the deduction for unreimbursed employee business expenses starting in 2018. That suspension was originally set to expire at the end of 2025, but the One Big Beautiful Bill Act, signed into law on July 4, 2025, struck the expiration date and made the suspension permanent.⁶

A narrow group can still deduct unreimbursed business meals on Form 2106: Armed Forces reservists, fee-basis state or local government officials, qualified performing artists, and employees with impairment-related work expenses.⁷ Everyone else depends on their employer’s reimbursement policy. Under an accountable plan, your employer reimburses business meals tax-free as long as you substantiate the expense and return any excess. Those reimbursements don’t show up in Box 1 of your W-2. Under a nonaccountable plan, or no plan at all, the full amount lands in your taxable wages.³

How the 50% Cap Works

Even when a business lunch fully qualifies, only half the cost is deductible. IRC Section 274(n) limits the deduction for food and beverages to 50% of the expense.² Tax and tip are part of the meal cost and fall under the same cap.³ So a $120 lunch (including $10 in tax and an $18 tip) produces a $60 deduction.

The reasoning is that you would have eaten lunch anyway, so Congress treats half the meal as personal nourishment.

The Per Diem Alternative for Travel

Instead of tracking every receipt on the road, you can use the IRS standard meal allowance based on federal per diem rates. For the period starting October 1, 2025 (covering most of the 2026 tax year), the meal-and-incidental-expense rates are $86 per day in high-cost localities and $74 per day everywhere else within the continental United States.⁸ Transportation industry workers use a separate rate of $80 per day for domestic travel and $86 outside the continental U.S.

The per diem simplifies recordkeeping, but the 50% cap still applies to the allowance amount. You also still need to log the date, destination, and business purpose of each trip.⁹

Meals That Are Fully Deductible

A few categories of food expenses escape the 50% cap and can be deducted at 100%:

Food at a company recreational event, like a holiday party or summer picnic. The event has to be primarily for employees rather than clients or owners.³
Meals provided to the general public as advertising or community goodwill, like grand opening catering or promotional food samples.³
De minimis workplace snacks — coffee, water, doughnuts, and occasional treats. The cost must be small enough that tracking it individually would be impractical, and the benefit needs to stay occasional. A daily catered lunch starts looking like disguised compensation.¹⁰

Bringing a Spouse Along

The cost of a spouse’s or dependent’s meal on a business trip is generally not deductible. The tax code blocks these expenses unless all three of the following are true: the spouse is an employee of your business, the travel serves a genuine business purpose for the spouse, and the spouse’s expenses would otherwise be independently deductible.¹¹ “My spouse helps me network at dinner” almost never passes. If a spouse tags along socially, deduct only your portion of the bill.

What You Have to Document

The IRS wants five pieces of information for every business meal you deduct:

The total cost, including tax and tip.
The date of the meal.
The restaurant’s name and location.
The names and business relationships of everyone at the table.
A brief description of what was discussed or the professional reason for the meal.

Record this at the time of the expense or shortly after. Reconstructing a year of business lunches from memory in April is exactly what falls apart in an audit.³

A physical receipt isn’t required for meals under $75, but the log entry still is. For any expense of $75 or more, keep the itemized restaurant receipt.³ Digital copies are fine as long as they’re legible and organized.¹² A photo of each receipt in a dedicated folder or expense app meets this standard for most small businesses.

Keep meal expense records for at least three years from the date you filed the return. If you underreported income by more than 25%, the IRS has six years to audit.¹³

Where to Claim the Deduction

The form depends on your business structure. Sole proprietors and single-member LLCs report deductible meals on Schedule C (Form 1040), Line 24b. The amount entered should already reflect the 50% reduction.¹⁴ Corporations use the deductions section of Form 1120, S-corporations use Form 1120-S, and partnerships report on Form 1065, with the expenses flowing through to partners on Schedule K-1. In every case, the figures need to match your documentation. Inconsistencies between reported deductions and underlying records are among the first things an auditor checks.

What Getting It Wrong Costs

Claiming personal meals as business deductions, or inflating meal expenses, doesn’t just cost you the deduction. If the IRS determines you underpaid taxes because of negligence or disregard of the rules, you face an accuracy-related penalty equal to 20% of the underpayment, on top of the tax you already owe, plus interest.¹⁵

Meal deductions draw disproportionate IRS attention because they’re easy to overstate and hard to verify after the fact. The problems auditors most often flag are deductions with no documented business purpose, meal expenses that are wildly out of proportion to the business’s revenue, the same meal claimed twice (once as a reimbursement and again as a deduction), and missing receipts for expenses over the $75 threshold. Clean records are the cheapest insurance against a penalty that can easily outstrip the value of the deduction itself.
