Research Tax Credit for Businesses: 2026 Guide
The federal Research Tax Credit remains one of the most valuable tax incentives available to businesses investing in innovation. Whether you’re developing new products, improving manufacturing processes, creating software, or advancing technology, qualifying research activities may significantly reduce your federal tax liability.
Here’s what businesses should know for 2026.
What Is the Research Tax Credit?
The Research Tax Credit, authorized under IRC Section 41, rewards businesses that invest in qualified research activities.
Businesses generally calculate the credit using one of two methods:
- Regular Research Credit, or
- Alternative Simplified Credit (ASC).
The credit is part of the General Business Credit and is typically calculated on Form 6765 before being reported on Form 3800.
Who May Qualify?
Research activities generally qualify if they:
- Involve technological research.
- Develop or improve a product, process, software, formula, or technique.
- Address technical uncertainty.
- Use a process of experimentation to evaluate potential solutions.
- Improve function, performance, reliability, or quality.
Businesses in industries such as manufacturing, engineering, software development, construction, architecture, and technology frequently qualify for the credit.
2026 Update: Section 174A Rules
Beginning with tax years after December 31, 2024, qualifying research is coordinated with the new domestic research expensing rules under IRC Section 174A.
As a result:
- Domestic research activities generally remain eligible for the credit.
- Foreign research activities generally do not qualify.
- Businesses should carefully document where research is performed.
Properly separating domestic and foreign research costs has become increasingly important.
Qualified Research Expenses (QREs)
Common Qualified Research Expenses include:
- Employee wages for qualified research activities
- Direct supervision and support of research
- Supplies consumed during research
- Qualified contract research expenses
- Certain computer rental and cloud computing costs used in research
Only properly documented qualified expenses are eligible for the credit.
Activities That Do Not Qualify
The IRS generally excludes several activities from the Research Tax Credit, including:
- Research performed after commercial production begins
- Customer-specific product adaptations
- Duplicating existing products
- Routine quality control testing
- Market research and consumer surveys
- Foreign research activities
- Funded research performed for another party
Not every development project qualifies, making a careful eligibility analysis essential.
Internal Software Rules
Software developed primarily for a business’s own internal use may qualify only if it satisfies additional IRS requirements demonstrating:
- Innovation
- Significant economic risk
- No commercially available alternative without substantial modification
These standards are generally more restrictive than those for software developed for customers.
Payroll Tax Credit for Startups
Certain Qualified Small Businesses (QSBs) may elect to apply up to $500,000 of the Research Tax Credit against the employer’s share of Social Security tax.
Generally, the business must:
- Have less than $5 million in current-year gross receipts.
- Have no gross receipts before the applicable five-year testing period.
This allows many startups to benefit from the credit even before becoming profitable.
New Form 6765 Reporting Requirements
For most 2026 tax returns, Form 6765 includes expanded reporting requirements.
Businesses may need to provide:
- Business-component level reporting
- Detailed Qualified Research Expense schedules
- Expanded supporting documentation
Maintaining detailed project documentation throughout the year is increasingly important.
Planning Tips
To maximize your Research Tax Credit:
- Track research projects from beginning to completion.
- Document technical uncertainty and experimentation.
- Separate domestic and foreign research expenses.
- Maintain detailed payroll and contractor records.
- Review Section 280C elections before filing.
- Prepare Form 6765 carefully to satisfy expanded reporting requirements.
