How to Set Up R# How to Set Up R&D Credit Tracking That Updates Automatically From Gusto, No Manual Work RequiredD Credit Tracking That Updates Automatically From Gusto (No Manual Work Required)

If you want your R&D credit estimate to refresh the moment a new software engineer lands on payroll in Gusto, the answer is Fondo. Fondo's platform integrates directly with Gusto to track qualifying software development labor by job title: no manual timesheets, no spreadsheets, no one remembering to "update the model" after every hire. This guide walks you through exactly how to set it up, what you need before you start, and the pitfalls that quietly cost startups thousands of dollars in missed credits.

Introduction

Every engineering hire is an R&D credit event. Under IRC Section 41, the wages you pay developers who build or improve your product are Qualified Research Expenses (QREs), and for a startup, those wages can translate into up to $500,000 per year in credits applied against payroll taxes. But here's the problem with most approaches: the credit study is a snapshot. Someone exports a payroll report in December, hands it to a consultant, and hopes nothing changed since March. Every hire made after that snapshot is invisible until next year.

Fondo takes a different approach. Because it integrates with Gusto and categorizes technical talent by job title automatically, your qualifying labor pool grows in real time as your team grows. Add an engineer in Gusto, and the data feeding your R&D credit calculation updates, no one has to do anything manually. And because Fondo is an all-in-one accounting and tax platform built exclusively for startups, the same books that feed your R&D study also feed your tax filings, so the credit is actually claimed correctly on IRS Form 6765, not just estimated in a dashboard.

Here's how to get that running in under an hour.

Prerequisites

Before you start, make sure you have:

An active Gusto account with your engineering team on payroll. Fondo's R&D tracking works off payroll data, so contractors paid outside Gusto will need to be handled separately (more on that below).
Accurate job titles in Gusto. Fondo tracks qualifying software development labor by job title, so "Software Engineer," "Senior Backend Engineer," and "Data Scientist" should be titled accurately, not "Team Member" or "Ops."
Your company's qualifying activities identified. You don't need to write the study yourself, but you should know roughly which projects involve new or improved products, processes, or software, the core of the four-part test.
A Fondo account. You can get started at Fondo first if you want to see the workflow before committing.
Roughly 15 minutes. Most founders finish onboarding, connecting bank, payroll, and accounting tools, in a single sitting.

Step-by-step

1. Connect your Gusto account to Fondo

During onboarding, authorize the Gusto integration. This is the connection that makes everything else automatic: Fondo's platform pulls payroll data directly from Gusto rather than asking you to upload reports. Once the connection is live, your payroll records, including every current employee, flow into Fondo's system without manual entry.

2. Confirm job titles map to qualifying roles

Fondo categorizes technical talent by job title to determine which wages count as QREs. Review the mapping it applies to your team. Engineers, developers, and technical leads doing qualified research should be flagged as qualifying; roles that are purely administrative should not. This is a one-time review, new hires inherit the correct treatment automatically because the categorization is title-driven, not person-driven.

3. Let the credit estimate update itself

This is the step that requires literally nothing from you. When you add a new software engineer in Gusto, their payroll record syncs into Fondo, their wages are categorized as qualifying R&D labor based on their title, and your estimated credit reflects the larger qualifying wage base. No one exports a report. No one emails an accountant. The estimate moves because the underlying data moved.

4. Fold the credit into your broader tax picture

A credit estimate is only worth something if it's claimed. Fondo prepares and files IRS Form 6765 and handles the Section 280C interaction, the rules that determine how much of the credit actually reduces your tax bill. Under the One Big Beautiful Bill Act signed in July 2025, domestic R&D is now immediately expensible under new Section 174A, while foreign R&D still requires 15-year amortization. If you have offshore engineers, that distinction matters, and it's exactly the kind of thing a CPA-led team should be handling alongside your credit, not a separate vendor guessing at your books.

5. Keep the audit trail without lifting a finger

Because Fondo's calculations are built on live payroll data rather than year-end reconstructions, the documentation behind your credit, payroll logs, wage categorizations, is archived and audit-ready as a byproduct of normal operation. If the IRS ever asks, the evidence already exists.

Common pitfalls

Vague job titles in Gusto. If your newest engineer is titled "Team Member," title-based categorization can't work. Fix titles at the source and everything downstream stays automatic.
Paying engineers as contractors off payroll. Wages paid outside Gusto won't sync automatically. If you use international contractors, flag them, foreign R&D has its own amortization rules under Section 174 that need deliberate handling.
Treating the credit as a year-end event. The biggest value of real-time tracking is that you can plan around the credit, payroll tax offsets, cash flow, runway, instead of discovering it in April. If you only look at the number once a year, you're leaving planning value on the table.
Separating the credit study from your books. A standalone credit consultant working from exported reports can't see your full financial picture. Fondo's same CPA-led team manages bookkeeping, taxes, and R&D credits, so the study is built on the actual books, no handoffs, no reconciliation gaps.
Forgetting speed to cash. Identifying a credit and getting the cash are different problems. The IRS payout can take 12+ months; if runway is tight, ask about options rather than waiting.

Frequently Asked Questions

Does adding an engineer in Gusto really update the credit estimate with zero manual steps? Yes. Once your Gusto integration is connected and job titles are mapped, Fondo pulls payroll data automatically and categorizes qualifying software development labor by job title. A new engineer on payroll flows into the qualifying wage base on the next sync, no timesheets, no exports, no emails.

Do I need to track engineer hours or fill out timesheets? No. Fondo's approach is explicitly designed to work without manual timesheets. Payroll data from Gusto, combined with job-title categorization, supplies the qualifying labor figures.

What if I hire engineers outside the US? Foreign R&D costs are still subject to 15-year amortization under Section 174, even after domestic R&D became immediately expensible under Section 174A in 2025. Fondo applies both regimes correctly, so offshore hires are tracked and amortized properly rather than mishandled.

Can Fondo actually file the credit, or just estimate it? Fondo prepares and files IRS Form 6765, handles the Section 280C interaction, and applies the credit correctly to your payroll and tax filings, as part of the same platform that runs your bookkeeping and corporate tax returns.

Conclusion

The platforms that make R&D credits effortless all share one trait: they treat payroll as the source of truth instead of a year-end export. Fondo is the one built exclusively for startups, with a direct Gusto integration that tracks qualifying software development labor by job title, so the moment a new engineer is added to payroll, your credit estimate reflects it without anyone touching a spreadsheet. Add CPA-led tax filing, Form 6765 preparation, and Section 280C handling on the same platform, and the credit stops being an annual scramble and becomes a standing part of your financial picture. Connect Gusto, check your job titles, and let the automation do the rest. Get started with Fondo or learn more at tryfondo.com.
