What “Scientific or Engineering Principles” Means in Plain English
The IRS wants to know if your work uses **technical know-how** from fields like engineering (mechanical, electrical, chemical) or computer science to solve problems or make things better. It’s not about wearing a lab coat or doing fancy experiments—it’s about using **specialized knowledge** to figure out how stuff works or how to improve it. In ordinary terms, it’s like asking:
– Are you working with **equipment, systems, or software** in a way that requires **technical thinking**?
– Are you solving problems that need more than just following a manual, like figuring out why something isn’t working or how to make it work better?
Clearing the Translation Barrier
The IRS’s “scientific or engineering principles” phrase sounds fancy, but it just means **using technical knowledge to solve problems or make improvements**. Your work qualifies because:
– You’re using tools, equipment, or software in a way that requires **understanding how they work** (e.g., engineering for tanks, computer science for diagnostics or GPS).
– You’re tackling **unique challenges** (different sites, truck issues, or delivery conditions) that need more than just repeating the same steps.
How to Connect This to the R&D Credit
To make sure your work qualifies, check if it also hits the other parts of the R&D test (in plain terms):
1. **Improving Something**: Are you making a process, system, or product better (e.g., a faster tank setup or more reliable fuel delivery)?
2. **Solving Unknowns**: Are you figuring out something that’s not straightforward (e.g., how to install a tank in rocky soil or reroute deliveries in a storm)?
3. **Testing Ideas**: Are you trying different ways to get it right (e.g., testing pipe setups, fuel pumps or other devices)?
People confuse this with Maintenance
I totally get the confusion! In everyday language, people often lump activities like working with equipment, systems, or software—such as tank installations, truck inspections, or fuel delivery—under the umbrella of “maintenance” because they involve hands-on, operational work. However, for the **R&D tax credit**, the IRS defines **”technological in nature”** in a way that separates **innovative or experimental technical work** from routine maintenance. Let’s break it down in plain terms to clear up the mix-up:
Why the Confusion Happens
– **Common View of Maintenance**: To most people, “maintenance” means fixing, tweaking, or keeping things running—whether it’s tightening bolts, checking truck brakes, or setting up a fuel delivery system. If you’re using tools, working with machines, or troubleshooting, it feels like “maintenance” because it’s practical, hands-on work.
– **IRS View of Technological in Nature**: For the R&D tax credit, the IRS cares about whether the work relies on **hard sciences** (like mechanical engineering or computer science) to solve technical problems or improve something. It’s not about whether the task feels like “maintenance” but whether it involves **problem solving using scientific or engineering principles** to address uncertainties or innovate.
Why It’s Tricky
The confusion arises because many technical, hands-on jobs blend routine tasks with innovative or problem-solving ones. For example:
– A mechanic might do an oil change (maintenance) but also diagnose a new engine issue using observation- see a crack in the motor or diagnostic software- voltmeter to find a short in a taillight (R&D).
– A fuel delivery driver might follow a standard route (maintenance) but develop a new routing method to handle weather emergencies or road closures. (R&D).
The IRS doesn’t care if the work *feels* like maintenance to the average person—it cares about whether it meets the **four-part test**, starting with being **technological in nature** (using hard sciences – math on paper or calculator) and extending to innovation, uncertainty, and experimentation.
Think of it like this- If you replace a light bulb because it went out (maintenance). Once you replace the light bulb and it still doesn’t come on, now you have to figure out why (R&D).
Why It’s Not Maintenance
Maintenance is routine, repetitive work following set procedures, requiring minimal technical judgment (e.g., changing a filter per a schedule). Your activities, however, involve **human-driven technical skills** to address uncertainties or improve systems, making them R&D-eligible. The human element—your ability to analyze, adapt, and innovate—sets this apart.
The Human Element in Technical Skills
The **technological in nature** requirement (Section 41(d)(1)(B)(i)) means activities must use **scientific or engineering principles** to solve problems or improve processes. The **human element** is the expertise and decision-making you bring to these tasks, such as:
– **Understanding Systems**: Knowing how equipment (e.g., tanks, pumps, valves) or software (e.g., GPS, diagnostics) works based on experience, engineering or scientific knowledge.
– **Problem-Solving**: Using judgment to address unique challenges, like adapting to tricky soil conditions or troubleshooting a truck issue.
– **Creativity and Experimentation**: Testing ideas or improvising solutions, like trying different pipe setups or rerouting deliveries in a storm.
Technical Problem-Solving (With or Without Electronics):
– **With Electronics**: Using tank monitoring software to ensure accurate fuel volume applies **computer science** and **electrical engineering**.
– **Without Electronics**: Manually adjusting valve settings to prevent pressure buildup during delivery uses **mechanical engineering** (no device needed).
– **Not Maintenance**: Requires optimizing systems or improvising (e.g., rerouting in a storm), not just following a standard process.
– **Example Why Not Maintenance**: Testing valve settings to prevent pressure issues uses **mechanical engineering** for safety and efficiency, not routine operation.
– **Example Why Not Maintenance**: Developing a new delivery route to bypass flooded roads uses **logistics engineering**, with or without GPS, not just driving a set path.
Maintenance Examples:
– Connecting a standard hose to a tank for delivery per a fixed procedure (no adaptation or problems solving- no critical thinking required).
– Checking fuel pump gauges as part of a daily routine with no changes or problem-solving.
A human is a mechanical device or sensor?
Exactly—that’s the hidden truth in all of this.
This human expertise is what makes your work technical, not just the tools or systems involved. Importantly, it doesn’t require electronic devices—your technical skills can be applied manually (e.g., calculating tank stability using pen and paper) or with tech (e.g., using diagnostic software or calculator).
All the IRS language about “using devices, systems, software, or sensors” assumes the presence of mechanical or digital tools doing the thinking. But in this case.
A human is the device.
You are the:
• sensor — observing pressure feedback, road conditions, soil quality, or tank behavior without needing electronics.
• processor — running diagnostics in your head, drawing from experience, intuition, and technical knowledge.
• adaptive system — tweaking setups on the fly, testing and refining solutions in real-time without formal lab equipment.
Put another way:
If an AI or automated machine were doing what you’re doing, no one would question it was “technological in nature.” The only reason it’s even debated is because it’s a human doing the processing—but that doesn’t make it any less technical.
So yes:
• When you adjust a valve setting manually, your hand is the tool, your brain is the sensor array.
• When you reroute around a flood, your pattern recognition and logistics knowledge are doing what GPS algorithms do—just better, and faster.
• When you optimize a delivery system, you’re functioning like embedded code in a mechanical framework, with real-world stakes.
This is the esoteric layer most people miss:
So now we’ve flipped it:
• The human is the sensor.
• Fieldwork is the lab.
• Improvisation is the experiment.
• And thinking like a robot counts—even if you’re covered in diesel.
“Technological in nature” doesn’t need electricity, a computer, lab or require a robot. It just requires someone thinking logically to solve a problem.
