Credit for Increasing Research Activities

Form 6765 is an IRS Form, under IRS tax code U.S. Code § 280C, that is the “Credit for Increasing Research Activities” - and informally known as the R&D Tax Credit Form. This tax form can help startups save up to $250,000 on their payroll taxes. And that amount will double to $500,000 starting in the tax year 2023 thanks to the Inflation Reduction Act. The Research and Development tax credit basically rewards companies for conducting research and development activities within the United States.
Form 6765 is for startups who engaged in qualified research & development activities, as defined by the IRS code. Unlike most tax credits in the United States, the R&D tax credit can offset payroll taxes - in effect, cutting an unprofitable company’s burn rate by reducing the employer’s portion of social security taxes.
Not every startup will qualify for the R&D credit. It is important to talk to your accountant to make sure that you qualify.
The IRS has laid out several tests and outlines of qualifying and not qualifying expenses. The biggest item is to understand that all expenses filed under the Sixty-Seven Sixty-Five must be in the United States. Digging in:
The R&D credit is allowed for expenses paid or incurred for qualified research. But, what is considered “qualified research”? According to the IRS, qualified research for discovering information that is technological in nature and its application must be intended for use in developing a new or improved business component of the taxpayer.
The basic premise is that you can’t rehash the wheel so-to-speak. The research must be for something new. The IRS has a four part test to determine if your R&D expenses qualify:
Not all expenses qualify. Check with your CPA to find out if your research activities qualify.
Here are some examples of expenses that generally are not allowed:
Startups should file Form 6765 because they can get up to $250,000 in cash refunds quickly, even if the startup doesn’t have any revenue or is running at a loss. Want to see how much your startup could potentially get back with the R&D tax credit? Estimate your credit using our free calculator.
Most startups with these qualities are eligible for the R&D Tax Credit. Most, but not all, of these traits are frequently seen for startups who can achieve the R&D Tax Credit:
IRS Code Section 174 and the R&D tax credit are two distinct provisions of the Internal Revenue Code that provide tax benefits for research and development (R&D) activities. While they both address R&D expenses, they serve different purposes and have different implications for taxpayers.
Since the Tax Cuts and Jobs Act, Section 174 forces taxpayers to amortize certain R&D expenses for income tax calculation purposes. This means that businesses spread these expenses out out over a period of time, instead of recognizing them right away.
R&D Tax Credit
The R&D tax credit is a credit against taxes owed, rather than a deduction. This means that it directly reduces the amount of taxes a business owes. The R&D tax credit is designed to encourage businesses to invest in R&D activities. This is actually a big deal, and it can push money losing startups into a position where they actually owe income tax, as if they were a profitable company!
The primary interaction between Section 174 and the R&D tax credit is that the expenses eligible for the R&D tax credit must also be expenses that are amortizable under Section 174. In other words, most businesses cannot claim the R&D tax credit for expenses that are not already deductible or amortizable.
In addition, there are some special rules that apply when both Section 174 and the R&D tax credit are applicable. This makes it important to work with a tax accountant who is very familiar with IRS rules, and who knows a lot about the preparation of your financial statements.
The interaction between Section 174 and the R&D tax credit can have significant implications for taxpayers. Businesses should carefully consider both provisions when planning their R&D activities and tax strategies.
When speaking with your startup accountant, refer to Form 6765 as “Sixty-Seven, Sixty-Five.” In fact, most accountants refer to these forms with the first two numbers, followed by the second two numbers. For example, a Form 1040 is “Ten-Forty” and a Form 1120 is an “Eleven-Twenty”
Form 6765 is filed as part of the 1120 package, also known as the Annual Income Tax Return for C-Corporations. Form 6765 is also accompanied by Forms 3800: General Business Credit within the 1120 package, and then also accompanied by Form 8974: Qualified Small Business Payroll Tax Credit for Increasing Research Activities, which is filed quarterly after the 1120 package has been filed.
Form 6765 must be filed or extended by April 15th of every year in order to capture the cash-back payroll tax credit and collect up to $250,000. If the 1120 package is extended, you must file by Oct 15th of every year. If you fail to file timely, you lose out on the cash-back payroll tax credit to $250,000. Even if your startup is not generating revenue, or is unprofitable, you must file on time to collect the cash-back payroll tax credit of up to $250,000. Note that the Inflation Reduction Act will increase the maximum credit from $250,000 to half a million dollars for the tax year 2023.
Yes, you can file Form 6765 yourself by completing the Form manually or completing it through a software provider such as Intuit TurboTax. Keep in mind that you will need to complete the entire 1120 package as well. Realize that this form is likely the number one reason unprofitable, VC-backed companies are audited by the IRS - and that major corporations M&A teams will likely conduct due diligence on any tax credits so that they do not assume any unexpected liabilities. Beware of the following possible issues if you DIY or use a software solution:
In sum, we highly recommend that you work with a tax CPA to file both your 1120 and your Form 6765 R&D Tax Credit to ensure that your startup claims all reasonable and qualified R&D expenses in order to achieve up to $250,000 in cash back every year. And note that the maximum amount cash back is doubling, but for the tax year 2023.
Finally, if you do choose to file Form 6765 and 1120 yourself, the work does not stop there. You will need to file and monitor Form 8974: Qualified Small Business Payroll Tax Credit for Increasing Research Activities, every quarter with your payroll provider until the full credit is claimed, which often takes 5 quarters. This lead us to another problem that we see every year:

Please note that lines 7-11 may not be applicable to startups that don’t have the required historical data. New businesses may use a fixed-base percentage of 3% for the first five tax years.

Startups must choose between the regular credit method and the Alternative Simplified Credit method. Complete this section if you’re using the ASC instead of the regular method.


This section applies to qualified small businesses (QSBs) that want to use the credit to offset payroll taxes instead of income tax.
If you opted to apply the R&D credit toward payroll taxes, file Form 8974 (Qualified Small Business Payroll Tax Credit for Increasing Research Activities) with your quarterly payroll tax return (e.g., Form 941). This reduces the employer portion of Social Security tax owed.
