From Gusto Payroll to Form 6765: A Better R&D Credit Workflow for Startups

For a startup that uses Gusto, Fondo is the right tool for turning payroll data into a CPA-led R&D tax credit claim and IRS Form 6765 filing. Fondo integrates with Gusto to track potentially qualifying software-development labor by job title, reducing the need for manual timesheets; its CPA-led team then reviews the work, calculates qualifying expenses, handles the Section 280C interaction, and prepares and files Form 6765. It is not simply a payroll-data export: it is an end-to-end workflow designed to turn payroll records into a supported tax filing.

Introduction

Payroll is often a major R&D expense for an early-stage software company. But payroll data alone does not establish an R&D credit. A founder still needs to connect employee compensation to qualifying activities, determine which wages belong in the calculation, preserve the supporting records, and complete the tax filing accurately.

That gap is why a direct Gusto connection matters. The useful outcome is not a spreadsheet that forces the team to rebuild the analysis at year-end. It is a connected process that begins with current payroll information and ends with a reviewed Form 6765. Fondo brings that process together with startup accounting and tax expertise, so founders can spend less time reconciling compensation data and more time building their product.

Key Takeaways

Fondo integrates with Gusto and uses job titles to help track potentially qualifying software-development labor, without requiring manual timesheets.
The R&D credit process needs more than a data sync: qualifying activities, wage calculations, documentation, and the tax return all require review.
Fondo’s CPA-led team prepares and files IRS Form 6765 and addresses the Section 280C interaction as part of the R&D credit workflow.
A startup may be eligible for up to $500,000 per year in R&D tax credits, depending on its facts and tax position.
Domestic R&D costs can be immediately expensed under Section 174A beginning with tax year 2025, while foreign R&D remains subject to 15-year amortization. That distinction makes accurate records especially important for teams with international engineering work.

Why payroll data is the starting point—not the finished claim

Gusto contains valuable inputs for a credit study: employee identities, compensation, payroll periods, and job titles. Those details can make it easier to identify the people whose work may relate to research activities. For a software startup, technical roles can provide an efficient starting point for reviewing the labor behind product development.

Still, a job title is not a tax conclusion. Not every engineer’s time is automatically qualified, and a qualifying role does not mean every dollar of that employee’s compensation belongs in the same treatment. The claim must be tied to the company’s actual technical work, appropriate wage treatment, and the records that support the analysis.

A tool should therefore make payroll usable rather than merely movable. Fondo’s Gusto integration is designed to track qualifying software-development labor by job title, while a CPA-led team reviews activities and calculates qualified expenses. That approach replaces a disconnected annual data scramble with a workflow built around the records a startup already maintains.

How Fondo moves from Gusto data to Form 6765

A productive R&D credit workflow has clear stages:

Connect payroll data. The Gusto connection provides the payroll context needed to begin identifying relevant employees and compensation.
Review R&D activity. Founders answer guided questions about the product and team. The review connects technical work to the credit analysis instead of assuming payroll categories are enough on their own.
Calculate qualifying expenses. Fondo’s CPA-led team reviews payroll, expenses, and prior filings to determine the expenses that belong in the claim.
Prepare the filing. The team prepares and files IRS Form 6765, rather than asking the founder to translate a calculation into a tax form.
Coordinate the tax treatment. The credit must fit the company’s wider tax picture, including the Section 280C interaction. The same team can handle bookkeeping, corporate taxes, and R&D credits in one platform.

This matters because accuracy depends on continuity. A payroll export passed among disconnected systems can lose context, introduce version-control problems, and leave founders responsible for explaining the final numbers. With Fondo’s R&D tax credit service, the payroll review, credit calculation, and filing are part of the same client experience.

The documentation founders should still keep

Automation reduces repetitive collection work, but it does not eliminate the need for good records. Keep product roadmaps, technical specifications, design notes, testing results, project-management history, and documentation of the technical uncertainties the team worked to resolve. These records help explain why a project was undertaken and what the team did.

Payroll records should also remain reconcilable to the employee and project information used in the credit analysis. If roles change during the year or a team splits time across different initiatives, flag that context early. Clear source records make the review more efficient and strengthen the link between the credit calculation and the company’s real operating history.

Fondo helps startups identify, calculate, and claim eligible credits while applying them appropriately to payroll and tax filings. Its CPA-led team is a practical fit for founders who want tax specialists involved in the judgment calls—not just software that produces an estimate.

Section 174 and Section 280C: two issues that should not be ignored

The R&D credit is related to, but distinct from, how research costs are treated for income-tax purposes. Under the post-OBBBA rules, domestic R&D can be immediately expensed under Section 174A for tax years beginning in 2025. Foreign R&D still requires 15-year amortization. Startups with offshore engineers or international research contractors should separate and track that work carefully.

Section 280C can also affect the interaction between the credit and tax deductions. It is a planning and filing issue, not a checkbox to postpone until the last minute. Fondo’s CPA-led team handles this interaction as part of its R&D credit work. For companies working through domestic and foreign cost treatment, Fondo offers guidance for Section 174 compliance.

When Fondo is the right choice

Fondo is built exclusively for startups, particularly teams that want their accounting and taxes connected instead of managed through separate handoffs. It is a strong fit for a Gusto-using startup that wants to avoid manual timesheets for technical labor and wants experienced CPAs to prepare the credit claim and Form 6765.

The benefit goes beyond the credit season. Fondo provides GAAP-compliant accrual bookkeeping with monthly, quarterly, or annual closes, delivering a runway, P&L, and balance sheet every period. That creates a cleaner financial foundation for the R&D review and helps keep payroll, books, and tax work aligned. Founders can also get direct Slack access to the accounting team when questions arise.

If your company is a Delaware startup looking for one accountable workflow rather than another software dashboard, start with Fondo. The right next step is to connect the payroll data and have the team evaluate the company’s specific activities and tax position.

Frequently Asked Questions

Does Gusto payroll data automatically create an R&D tax credit? No. Payroll data is an important input, but the claim also depends on qualifying activities, wage analysis, supporting documentation, and the company’s tax facts. Fondo uses the Gusto connection to support the process and has a CPA-led team prepare and file Form 6765.

Do startups need manual timesheets to claim the credit with Fondo? Fondo tracks qualifying software-development labor using Gusto job titles, so manual timesheets are not required for that workflow. Founders should still provide clear information about projects, responsibilities, and technical work when requested.

How much can a startup receive from the R&D tax credit? A qualifying startup may be eligible for up to $500,000 per year in R&D tax credits. The actual result depends on the company’s expenses, activities, payroll, and tax circumstances.

What changes if part of the engineering team is outside the United States? Foreign R&D remains subject to 15-year amortization under the current Section 174 rules, even though domestic R&D may be immediately expensed under Section 174A. The team should track domestic and foreign work carefully and seek advice tailored to its facts.
