Research Activities Credit

The research activities credit is a US federal tax credit that rewards businesses for spending on qualifying research and development, often called R&D. It reduces the tax a company owes, dollar for dollar, so a dollar of credit is worth more than a dollar of deduction.

It is aimed at companies that develop or improve products, processes or software.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

Governments want businesses to invest in innovation, but R&D is risky and the benefits spread beyond the company that pays for it. The research activities credit, also called the R&D tax credit, is the US answer: a direct reduction in income tax linked to the amount a business spends on qualifying research.

Not every project qualifies. In general the work must aim to create or improve a product, process, formula, software or technique, depend on engineering or science, involve uncertainty about how to reach the result, and use a process of experimentation.

Routine testing, market research and cosmetic changes normally do not qualify. Qualified research expenses typically include wages for staff doing or directly supervising the research, supplies consumed in the work, and a share of amounts paid to outside contractors.

The company must keep records showing who did what, which project it served and how much time was spent. There are different ways to compute the credit.

A common one, the alternative simplified method, gives a set percentage of qualified spending above a base worked out from the previous three years, while the regular method uses a fixed base percentage. Small start-ups with little or no income tax may be able to use part of the credit against payroll tax instead, which turns a credit they cannot use into real cash.

The rules, rates and limits are set by legislation and change from time to time, so a tax adviser should confirm what applies. Finance teams value the credit because it improves the real cost of innovation, but it brings an audit risk.

Poor documentation is the most common reason claims are reduced.

In practice

Real-world examples.

1

Example

A medical device maker spends $1,500,000 on engineers designing and testing a new sensor. Its tax team tracks time by project and claims the credit on wages and prototype materials, while excluding the cost of marketing the finished product.

2

Example

A food company develops a new method for preserving fresh sauces. It records the failed trials, the changes in process and the staff involved, because that experimentation is the evidence needed to support a claim.

3

Example

A two-year-old software start-up has no profit and so owes no income tax. It elects to use part of its credit against payroll tax, and the finance manager treats the saving as extra runway for hiring.

Formula

Calculation

Credit (alternative simplified method) = credit percentage x (current-year qualified research expenses - 50% of the average qualified expenses of the prior three years). The percentage is set by law; this illustration assumes 14%. Suppose a software company has current qualified research expenses of $900,000, and prior three-year expenses of $600,000, $700,000 and $800,000. The average = (600,000 + 700,000 + 800,000) / 3 = $700,000, and the base = 0.50 x 700,000 = $350,000. The excess = 900,000 - 350,000 = $550,000. Credit = 0.14 x 550,000 = $77,000, which reduces the tax bill directly.

Case study

Seen in the real world.

Brightwater Robotics is an illustrative, fictional company that builds warehouse sorting machines. For years it deducted its engineering payroll as an ordinary cost and never considered a claim.

An outside adviser reviewed projects and found that about 60% of the engineering team's time, or roughly $1,800,000 of a $3,000,000 payroll, met the tests for qualifying research. After excluding supervision of routine support work, the adviser applied the alternative simplified method with a base amount of $700,000, giving a credit of 14% x (1,800,000 - 700,000) = $154,000 in this illustration.

Brightwater set up time-tracking by project so that the claim would survive review in later years. The illustrative lesson is that the credit is often available to companies that do not think of themselves as research firms, provided that records are kept as the work is done.

Watch out

Common mistakes.

  • Assuming only laboratories and large technology firms qualify, when manufacturers, food producers and software companies often do too.
  • Claiming the credit without contemporaneous records, since time sheets and project notes written long after the event are weak evidence.
  • Counting every engineer's full salary as qualified spending, when time on routine maintenance or support does not qualify.

Questions

People also ask.

Is the credit the same as a deduction?

No, a deduction reduces taxable income while a credit reduces the tax itself, so a credit is generally more valuable per dollar.

Can a loss-making start-up benefit?

Some qualifying small businesses can apply part of the credit against payroll tax, which provides a benefit even without income tax.

Do other countries have similar schemes?

Many do, under names such as R&D tax relief or innovation credits, but the rules and definitions differ, so they should not be assumed to match the US rules.
