What Actually Qualifies as a Business Expense (And Why Your Credit Card Matters)

The distinction between personal and business expenses may seem black and white to outsiders, but once you’re running a business, you’ll often find yourself in a coffee shop wondering if it’s a write off, or getting a new computer and having to calculate what percentage of use is “business use.” Every business owner learns this (typically) the hard way – which is why, come tax time, they’re knee deep in receipts half of which they can’t even decipher.

The IRS has some guidelines to help – but when it comes to real life examples, it’s not always so cut and dry. Essentially, an expense must be considered “ordinary and necessary” to be deductible. Ordinary means it must be common within your field. Necessary means it must be helpful and appropriate. Note that necessary does not mean essential – you don’t need to prove that you’d go out of business without it.

What Is Not in Dispute

Some expenses are indisputable. Rent, salaries of employees, insurance for business (not health), supplies for work purposes only – no one is going to fight you on that. Printer paper you buy for your office is a business expense. If you pay someone to draw your logo, it’s a business expense. These are the no-brainers.

But most business expenditures fall outside of the categorical dedications. This isn’t how real business works, even if the tax guide examples show otherwise.

Where It Gets Complicated

This is where business owners start to question themselves. If I take a client out to lunch, it’s only 50% deductible as a business meal. If I fly out for a conference, the ticket is justified, but if I add additional days for vacation, I have to apportion it. If I work from home and use my personal phone for calls, I can only deduct the business portion – but I better justify what that portion actually is.

And too many business owners avoid claiming anything that could be flagged in an audit. That’s one approach, but it leaves money on the table. The other approach is ensuring everything is properly documented so legitimate claims – even with added scrutiny – are perfectly allowable.

This is where your payment method matters more than you think. A specific business credit card creates the paper trail that separates business purchases from personal ones. Come tax time, all you have to do is review the statement on the associated card versus painstakingly combing through your personal account statement to highlight all of the proper purchases.

The Documenting Issue

It’s not only about how much you spent either. The IRS wants to know what you bought, when you did it, where you went, who was involved and what business there was to support this expense. This seems excessive when it feels like they just want to ensure you’re not writing off your entire life as a business expense.

Think about it: A receipt from a restaurant is not enough to justify your claim – you need to point out who you met with, what minutes were taken during this meeting outside of the office. A hotel receipt does not mention why you’re there, or the context. Documentation includes the receipt and enough context to appropriately justify the business intention.

What catches people off guard? The requirement to do this in real time as opposed to six months down the line when you’re up against tax claims. You may not remember why you drove where you drove in March when it’s now December. But it takes five seconds to write “client meeting” on a receipt in real-time. Reconstructing an entire year from a pile of crumbled receipts takes hours – and likely some creative embellishing.

Common Areas of Grey Confusing Everyone

Home office deductions – This makes everyone anxious because there is a specific rule of thumb. The space must be regularly used and exclusively used for the business endeavor. Therefore, your kitchen table where you also eat cereal does not count but your spare bedroom that has been converted into an office does. Thus, this makes excess people either let money fall by the wayside by not taking the deduction or make a claim too egregiously and reap the consequences.

Vehicle expenses – Good luck with this one. You can deduct mileage traveled for business purposes but not for the commute home to your regularly established place of employment (though if that place is your house – and it technically should not be – this gets convoluted). But if you take your work vehicle home without permission from your boss, it’s on you unless you’re making client calls as a regular function of your employed role.

Clothing almost never counts unless it’s literally uniform or something that you could not wear outside the realm of work. Thus, your three-piece business suit does not count (no matter how much cash you’ve spent). Your nursing scrubs with the embroidered company logo likely does.

Education and training qualifies when they maintain or improve skills already attained from your current company – but not if the education prepares you for another field entirely. This creates some weird scenarios like certain classes count and other ones don’t because of what you’re learning and why.

Why Having the Wrong Credit Card Penalizes You

When your personal credit card doubles as your work credit card, you’re doing double the work for yourself every month as you meticulously attempt to categorize certain cards except for others while inevitably giving up halfway through after you’ve forgotten about certain transactions. In other words, you’re missing out on legitimate claims while further complicating any future audit you may have.

Using separate cards creates what accountants term a clean ledger. Everything on that credit card statement can be proven as part of your business. Your bookkeeping is easier. Your audit process is less complicated. The same goes for tax time quarterly as you’re trying to justify purchases on time instead of coming up short-handed at the end.

Some credit cards summarize purchases too – whereas expense tracking helps in differentiating categories as well so when you see certain expenses already categorized automatically by type of purchase – which helps tremendously because six weeks later when you’ve forgotten that $47 purchase is going to require some detective work – and probably 12 levels of frustration.

What Happens When You Get It Wrong

For small mistakes, the IRS does not mind error – it’s expected among taxpayers – and therefore they give flexibility in amounts owed throughout the year versus what’s claimed come tax time. It’s only when there’s a consistent pattern of abuse in looking suspicious – or wholly inappropriate claims – that raise red flags and invite audits.

Therein lies the problem by being either conservative (claiming almost nothing) or aggressive

(claiming anything). Both approaches penalize those owners – one who ends up with nothing and one who’s audited for an eagle eye over expenses that show grocery store receipts.

Setting Yourself Up for Success

Most of this becomes easier when you set reasonable expectations from the outset – pay business purchases on a business credit card, save receipts with notes about business purpose immediately, review monthly instead of waiting until tax time.

None of it is terribly hard – but all requires consistency, especially if it’s boring work that should get done in real-time instead of scrambling later on behind closed doors.

Additionally, providing clarity as to what’s a proper business expense helps you not only understand but hopefully justify certain expenditures; if you know something likely won’t be a deductible expense, you’ll likely think twice before spending money on it regardless of investment potential within your market; if you know something could be fully deductible – or at least partially – you’ll feel more justified spending the money.

These rules exist for good reason – even if they sometimes feel arbitrary along the way. Learning how to navigate sensibly within them – maximizing your reasonable deductions – isn’t how to make arbitrary gains; it’s how to run your successful operation based off accurate assessments – and your credit card selection is one small factor (albeit one that’s easier when all else fails).
