5 tax deductions small businesses often miss

Running a small business means wearing every hat at once, and when you are focused on serving clients and keeping the lights on, tax deductions are easy to leave on the table. Over the years we have reviewed hundreds of returns that were prepared elsewhere, and the same handful of write-offs come up again and again as ones that were missed. None of these are exotic loopholes. They are ordinary, fully legitimate deductions that the tax code allows for businesses of every size. Below are five of the most common, with notes on how to qualify and what records you should keep.

1. The home office deduction

Many owners assume the home office deduction is a red flag or that it only applies to full-time remote workers. Neither is true. If you use a specific area of your home regularly and exclusively for business, you may be able to deduct a portion of your rent or mortgage interest, utilities, insurance, and repairs. The space does not need to be a separate room, but it does need to be used only for business. You can use the simplified method, which is a flat rate per square foot, or the actual-expense method, which often produces a larger deduction if your home costs are high. Keep a simple diagram of the space and a record of your total home expenses for the year.

2. Vehicle and mileage expenses

If you drive for business, whether that is visiting clients, picking up supplies, or traveling between job sites, those miles are deductible. The catch is documentation. The IRS expects a contemporaneous log showing the date, destination, purpose, and miles for each trip. A phone app that tracks this automatically is well worth the small cost. You can deduct using the standard mileage rate or your actual vehicle costs, but you generally have to choose carefully in the first year you use the car for business, so it pays to plan ahead with your preparer.

3. Retirement contributions

This is the deduction that quietly builds real wealth while lowering your taxable income at the same time. A SEP-IRA lets you contribute a meaningful percentage of your net self-employment income, and a Solo 401(k) can allow even larger contributions for a one-owner business. Contributions reduce your current-year taxable income and grow tax deferred. If you have employees, there are options designed for you too, and the setup costs themselves may qualify for a credit. The key is to decide and fund before the deadlines, which is why we like to talk about this well before filing season.

4. Software, subscriptions, and tools

The accounting software, design tools, scheduling apps, cloud storage, and industry subscriptions you use to run the business are ordinary and necessary expenses, and they add up faster than most owners realize. The same is true for a portion of your phone and internet if you use them for work. Keep digital receipts in one folder so that nothing gets forgotten at year end.

5. Professional and educational fees

Fees you pay to your accountant, bookkeeper, attorney, or other advisors are deductible, and so is continuing education that maintains or improves the skills your business relies on. Conference registration, online courses, professional memberships, and the trade publications you read for work all count. Think of it this way: investing in better advice and better skills is one of the few expenses that can pay for itself twice.

The theme across all five is the same. Good records turn money you already spent into real tax savings. If you are not sure whether something qualifies, keep the receipt and ask. It is far easier to decide with the documentation in hand than to reconstruct it months later.
