If your company invests in research and development (R&D), you’ve probably heard about Section 174 of the Internal Revenue Code. It’s one of those tax rules that sounds intimidating at first but can actually save you a ton of money—if you know how to play it right.
So, what actually counts as Section 174 expenses? How do you recover those costs? And maybe more importantly, what doesn’t qualify? Let’s walk through some practical Section 174 expenses examples so you can see how this applies to your business.

What Qualifies as Section 174 Expenses?
At its core, Section 174 was designed to encourage innovation. Instead of letting you deduct all your R&D costs in one shot, the IRS requires you to capitalize and amortize those expenses over five years. In other words, you spread the benefit out over time.
Direct Costs
These are the easy ones. Paying your engineers to build a prototype? Buying lab supplies? Running tests on a new product design? All of those fall into the “direct” category.
For example, if your biotech startup hires scientists to experiment with new formulas, their salaries are Section 174-eligible. Same goes for the chemicals, testing equipment, and even trial batches they burn through along the way.
Indirect Costs
Here’s where companies sometimes overlook opportunities. Not all qualifying costs are hands-on. Think about the electricity that powers your lab, the rent for your research space, or even administrative salaries tied to managing R&D projects. These “overhead” costs can also qualify.
And here’s a key difference: success or failure doesn’t matter. You could sink money into a project that never sees daylight, and those expenses may still count.
Examples of Activities That Fit Section 174
Section 174 casts a wider net than most people realize. Here are a few types of work that usually qualify:
- Fundamental research that aims to create entirely new knowledge.
- Applied research for building or improving products and processes.
- Work performed after production starts but before you’ve resolved all the uncertainties.
Picture a SaaS company building a new app. The coding, debugging, and testing phases may qualify—even if the business is already selling other software.

How Do You Recover Section 174 Costs?
This is where the rubber meets the road.
The Five-Year Amortization Rule
The IRS now requires businesses to spread their R&D deductions over five years. So, let’s say your company racks up $500,000 in qualifying R&D costs this year. Instead of taking the full deduction upfront, you’ll expense about $100,000 per year over the next five years.
It’s not as immediately satisfying, but it provides a steady benefit—and it’s the law.
Why It Affects More Than You Think
This requirement can ripple through other parts of your tax planning. Capitalizing R&D expenses can temporarily bump up your taxable income, which might affect deductions or credits elsewhere.
That’s why strong documentation matters. Keep track of who worked on what, what materials were used, and why the work qualifies as R&D. Good records not only help at tax time but also protect you in case of an audit.
Special Considerations for Section 174
Some situations aren’t so cut-and-dry.
For example, if your company reimburses a subsidiary for R&D expenses, both parties may still qualify for Section 174 deductions. The outcome of the project doesn’t matter—it’s the nature of the expense that counts.
That means if your engineering firm spends years developing a new building process that never gets used commercially, you may still get tax benefits from those costs.
Exclusions: What Doesn’t Qualify
Not all R&D spending falls under Section 174. Some common exclusions include:
- Buying land or depreciable property.
- Research after full-scale commercial production starts.
- Market research or consumer surveys.
- Quality control testing.
- Research funded by someone else, like a grant.
So if your marketing team is running focus groups to test consumer interest, that’s not an R&D expense—it’s just marketing.
Why Documentation is Your Best Friend
Imagine you’re running a software project. Developers working on experimental features? That counts. Developers fixing routine bugs in your current product? Probably not.
That’s why meticulous documentation is your safety net. Break down projects, track hours, and record the purpose of each task. Without it, you’ll struggle to defend your claim.
Since 2022, the IRS has required mandatory amortization of R&D costs. That means startups and established firms alike can no longer deduct everything in one year. For some businesses, this has meant a bigger tax bill upfront.
But don’t let that discourage you. Over time, these rules still provide valuable tax benefits—and in many cases, can be combined with credits for even bigger savings.
Tools like TaxRobot’s top-rated R&D tax credit software can automate the process, making sure you’re capturing every eligible expense without drowning in spreadsheets.
The Bottom Line
Section 174 may look like dry tax code, but it’s a powerful tool for businesses that invest in innovation. Whether you’re in software, biotech, engineering, or manufacturing, understanding which expenses qualify—and how to recover them—can save you serious money.
The essentials:
- Track both direct and indirect R&D costs.
- Don’t stress about failed projects—they often still qualify.
- Amortize costs correctly over five years.
- Document everything.
Handled right, Section 174 isn’t just about compliance. It’s about turning your R&D efforts into a tax-smart growth strategy.
