Paying people to take part in research is standard practice, a meaningful budget line and a documented factor in whether participants enroll and stay through completion. Yet the way participants are paid has often failed to keep pace with the rest of research operations. Mailed checks, site-held cash and manually distributed gift cards remain common, even as the rest of clinical operations has gone digital. That gap matters because participant payment is more than a thank-you; it is part of the infrastructure of access.
Reimbursing travel, caregiving and lost wages can reduce the financial barriers that keep lower-income and underserved groups out of studies, while the payment process itself sits within a web of IRB oversight, tax requirements and increasingly ambitious federal enrollment policy. For sponsors, it is also one of the few recruitment and retention levers they directly control. Handled well, participant payment and research incentives can widen access, improve retention and support more representative research. Handled as petty cash, it becomes a liability.
How payment friction drives participant dropout
A participant who pays $40 for parking and gas, then waits three weeks for reimbursement, is effectively financing part of their own participation. For someone without a bank account, a mailed check creates another barrier altogether. Slow or inaccessible payments add to the participant burden a study is already trying to overcome. Digital and prepaid options can reduce that friction by putting funds in participants’ hands faster and removing the mailroom from the process. The stakes are significant:
- Roughly 80% of clinical trials are delayed by recruitment problems
- 30 to 40% of enrolled participants drop out before the end
- Delays can cost a sponsor hundreds of thousands to millions of dollars per day
Participants often leave because of the burden surrounding a study: travel, time off work and caregiving. Automating research participant payments won’t remove those barriers, but it can stop payment from becoming another one.
Automating participant payments and research incentives
The goal is simple: connect payments to the systems already running the study so a completed visit, approved milestone or expense can trigger payment without a coordinator processing it by hand. Digital and prepaid cards speed up delivery without requiring bank details, while choice-based rewards and international options support broader participant groups. Each payment is also logged, creating a clearer record for reconciliation, tax tracking and study oversight. For lighter-touch research, such as patient surveys, real-world evidence panels and market research incentives, platforms that send branded, choice-based digital rewards in bulk cover most of the need without a specialized stipend system. Regulated trials add IRB oversight and participant-level tax tracking, so they may require a dedicated trial-payment platform alongside the rewards layer.
Paying participants ethically: what IRBs look for
Regulators care about how participants are paid, not just how much. The FDA and OHRP distinguish reimbursement for expenses such as travel and lodging from incentive payments, which can raise concerns about undue influence and are reviewed by an IRB for amount, method and timing. OHRP recommends payments accrue and are prorated as a study progresses rather than withheld until completion, since a large final payment could pressure someone to stay. Prorated, milestone-based payments are straightforward in principle but cumbersome to administer manually. Automation makes the payment schedule easier to apply consistently at scale.
Staying compliant as the rules tighten
Two developments make manual payment tracking harder to defend. First, participant diversity. The Food and Drug Omnibus Reform Act created statutory Diversity Action Plan requirements for certain clinical studies, pushing sponsors to think more deliberately about enrollment barriers and how they will support representative participation. Second, tax reporting. From January 1, 2026, the federal Form 1099 reporting threshold for certain payments increased from $600 to $2,000, affecting how institutions track and report qualifying participant compensation. Compensation remains taxable, so institutions still need to track cumulative payments accurately and identify when reporting thresholds are reached. That is much easier when every payment is recorded automatically rather than split across cash, checks and manually distributed gift cards.
Frequently asked questions
Are research participant payments taxable?
Yes. US research participant payments are generally taxable income. From January 1, 2026, the Form 1099 reporting threshold increased to $2,000 per participant per year. Documented expense reimbursements are generally treated separately.
Can research participant payments be automated?
Yes. Rewards platforms such as Giftogram can automate reward delivery by connecting participant payments to research workflows and other business systems.
Can you pay international research participants?
Yes, but reward availability varies by country. Before launching your study, check which incentives are available in each participant’s market, as this can affect how much to offer and the type of reward you use.
What is the best way to pay research or survey participants?
Digital rewards or corporate gift cards are a flexible option for high-volume participant programs; Giftogram lets organizations send gift cards and prepaid cards in bulk, with recipient choice and centralized tracking.
How do you pay research participants in bulk?
Upload a recipient list or connect your research workflow to a rewards platform like Giftogram, which supports bulk sending and API-based reward delivery, reducing the need to process each payment manually.
