Commonly Missed Deductions

Many small business owners overlook the tax savings hidden in day-to-day expenses. We’ll dive into a few areas that often go unnoticed, helping you keep more of your hard-earned money.

Home Office and Vehicle Expenses

Do you work from home or use a vehicle for business? If so, you might qualify for deductions that can relieve some financial pressure. The home office deduction is one that many overlook. It applies if you use a specific area in your home exclusively for business. Don’t forget about vehicle expenses either. Whether it’s mileage, gas, or other vehicle-related costs, these can add up. Keeping track of these through a detailed logbook or app can be a game changer.

Imagine driving your car 10,000 miles a year for business purposes. With a deduction rate of 58.5 cents per mile in 2025, that’s a potential deduction of $5,850. It’s easy to see why this shouldn’t be missed. Start tracking today and see the difference.

Health, Retirement, and HSA Deductions

Your well-being can save you money through health and retirement deductions. Small business owners often forget about the tax benefits linked to health savings accounts (HSAs) or retirement contributions. By contributing to an HSA, you can deduct up to $3,650 for self-only coverage or $7,300 for family coverage.

Retirement contributions, like those made to a SEP IRA, offer significant savings as well. Maximize these benefits by contributing as much as you’re allowed. Small steps today can lead to big savings tomorrow. Check out this resource for more ideas on health and retirement deductions.

R&D, Section 179, and Bonus Depreciation

Investing in your business might qualify you for deductions you didn’t know about. Research and Development (R&D) deductions are available if you’re creating or improving products. Immediate expensing under the Section 179 allows you to deduct the full cost of equipment in the year of purchase.

Bonus depreciation is another option, letting you write off a large percentage of the cost of assets. Consider this: A $10,000 equipment purchase can significantly reduce your taxable income. Keep these strategies in mind when planning purchases and improvements. Learn more in this article.

How to Claim Deductions in 2026

The rules for claiming deductions are changing. Here’s what you need to know to claim what’s yours under the new regulations.

Updated Home Office Deduction Rules

With changes in tax laws, the home office deduction has specific requirements. You need to use a part of your home exclusively for business. This can include a desk in a spare room or a dedicated home office.

The deduction is based on the percentage of your home used for business. For example, if your home office is 10% of your home’s square footage, you can deduct 10% of your utility costs. Simple tracking of your expenses will help ensure you’re ready during tax season. Gain deeper insights with this guide.

Mileage Deduction 2026 Rate Explained

The IRS sets a standard mileage rate each year, and for 2025, it’s 58.5 cents per mile. This rate helps cover the cost of using your vehicle for business.

Keep a detailed log of your trips, including dates, miles driven, and purposes. This ensures you have the records needed if questioned. Proper documentation can transform a routine task into a significant tax advantage.

Immediate R&D Expensing and SALT Cap

The rules for R&D deductions now allow for immediate expensing. This means you can write off costs in the year they occur, freeing up capital. The SALT (State and Local Tax) cap of $40k brings challenges, but strategic planning can help.

Consult a tax advisor to navigate these changes and optimize your savings. They can help you make the most of these deductions and avoid pitfalls. For more information, visit this link.
