📘 IRS Publication 535: What It Says (and Doesn’t Say) About the R&D Tax Credit 🧾💼

Hey founders, tax advisors, and business owners 👋—if you've ever read through IRS Publication 535 looking for guidance on the R&D Tax Credit, you might’ve come away...confused. That’s because Pub 535 is a key resource for understanding deductible business expenses, but it only briefly touches the R&D Credit. Let’s break down what it covers—and what it doesn’t. 📉📚

📌 What Is IRS Publication 535?

IRS Pub 535, titled Business Expenses, outlines which business costs are deductible for federal tax purposes. It’s a must-read for understanding operational write-offs like rent, utilities, and employee benefits.

But what about research and development? That’s where things get nuanced.

🧪 What It Says About R&D Expenses

Pub 535 covers R&D under the section titled "Research and Experimental Costs" and gives two primary options:

1. Deduct in the year incurred 🗓️

2. Capitalize and amortize over time 🏦

It references Section 174 of the tax code—not the R&D Tax Credit under Section 41. Still, it’s relevant if you’re trying to decide how to handle R&D costs before you even get to the credit.

🔄 How It Relates to the R&D Tax Credit

• ✅ Section 174 (Pub 535) is about how you treat the expense

• ✅ Section 41 (R&D Tax Credit) is about how you claim a credit for qualifying activities

Both sections impact how your R&D is handled on your tax return, but they are not interchangeable.

🚨 What Pub 535 Does NOT Do

• ❌ It does not define qualified research for credit purposes

• ❌ It doesn’t walk you through Form 6765 (that’s where you claim the credit)

• ❌ It doesn’t help you calculate your QREs (Qualified Research Expenses)

For that, you’ll need Section 41 regulations and IRS audit guidelines specific to the R&D Tax Credit.

🧾 Takeaway for Businesses

• 📁 Use Pub 535 to understand how to treat your R&D costs on the books

• 📘 Use IRS guidance on Section 41 to determine eligibility for the R&D Tax Credit

• ✅ Coordinate with your tax advisor to apply both correctly

💬 Final Word: Two Sections, One Strategy

Think of Pub 535 and the R&D Tax Credit as two parts of the same playbook. One tells you how to expense research costs; the other shows you how to get rewarded for innovation.

Don’t stop at Pub 535—go deeper. Your tax savings depend on it. 💡💰
