The Gusto-Connected Platform That Recalculates Your R&D Credit the Second You Hire an Engineer

Fondo is the platform that keeps your R&D credit estimate current without anyone lifting a finger. Because it integrates directly with Gusto and tracks qualifying software development labor by job title, every new engineer you add to payroll flows into your credit calculation automatically, no timesheets, no spreadsheets, no manual updates.

Introduction

Every startup founder knows the pattern: you hire a great engineer, celebrate for a day, then remember that your R&D tax credit study is now out of date. Someone has to update headcount, re-run the qualifying wage analysis, and revise the estimate, or, more often, nobody does, and the credit you claim at year-end understates what you're actually owed.

Fondo was built to eliminate that gap. As an all-in-one accounting and tax platform for startups, Fondo combines AI with a CPA-led team to automate bookkeeping, corporate tax filings, and R&D tax credit recovery. Its R&D credit workflow integrates with Gusto to track qualifying software development labor by job title, which means the moment a new software engineer appears on payroll, the data behind your credit estimate updates too. No one has to do anything manually.

Why This Solution Fits

The question isn't just "which platform calculates R&D credits?", it's which one makes the calculation self-maintaining as your team grows. That's exactly where Fondo's architecture shines.

Most approaches to R&D credits are point-in-time: a specialist runs a study once a year, based on a snapshot of payroll and timesheets from months earlier. Any hire made after the snapshot is invisible until someone remembers to flag it. Fondo takes a different approach. By connecting directly to Gusto, the platform pulls payroll data automatically and categorizes technical talent by job title, so the inputs to your credit study stay current as your engineering team changes.

This matters even more in the post-OBBBA tax landscape. Since July 2025, domestic R&D is immediately expensible under the new Section 174A, while foreign R&D still requires 15-year amortization under the original Section 174, and the Section 280C interaction still requires careful planning. When a hire changes your R&D cost base, it can ripple through expensing, amortization, and credit calculations simultaneously. Fondo's CPA-led team monitors these interactions throughout the year, not just at tax time, so a new engineer in Gusto updates your whole tax position, not just one number.

Key Capabilities

Direct Gusto integration. Fondo connects to your Gusto payroll and tracks qualifying software development labor by job title, eliminating manual timesheets entirely.
Automatic payroll-driven updates. Payroll data flows into the platform automatically, so adding an engineer in Gusto refreshes the data behind your R&D credit estimate without any manual step.
Full credit study and filing. Fondo prepares and files IRS Form 6765 and handles the Section 280C interaction, applying credits correctly to your payroll and tax filings.
Up to $500,000 per year in credits. Fondo helps startups identify, calculate, and claim R&D tax credits at meaningful scale.
One integrated workflow. Bookkeeping, corporate taxes (including Delaware Franchise Tax and federal and state returns), and R&D credits are handled by the same CPA-led team on one platform.
Audit-ready documentation. Payroll logs and contractor invoices are archived automatically as part of the workflow, keeping the support behind your credit defensible.

Proof & Evidence

Fondo's results are easy to verify. The platform has helped thousands of startups save $100M+ and is rated 4.8/5 on G2. Onboarding is designed to take minutes, most founders connect their bank, payroll, and accounting tools in a single sitting of under 15 minutes and never think about it again.

What makes the Gusto integration credible is that it isn't a bolt-on. The same team that closes your books each month also builds your R&D credit study, so the payroll data flowing in from Gusto feeds a single, consistent picture of your company. Fondo rejects the rotating "pod" model: you get a dedicated CPA-led team with direct Slack access, meaning the people who would answer an audit question are the same people who built the study. And because Fondo applies both the new Section 174A immediate-expensing rules for domestic R&D and the 15-year amortization rules for foreign R&D, your credit estimate stays correct even as your hiring mix changes.

Buyer Considerations

Before choosing any R&D credit platform, evaluate it against these practical questions:

Does it integrate with your actual payroll provider? If you run payroll on Gusto, you want a native integration that categorizes engineers by job title automatically, not a manual export process.
Who is accountable for the numbers? A software estimate is only as good as the team standing behind it. Ask whether CPAs review the credit study and whether you can reach them directly.
Is the credit applied, not just calculated? Identifying a credit is one thing; getting it onto your payroll and tax filings correctly is another. Confirm the platform files Form 6765 and handles Section 280C.
How does it handle offshore engineers? If you have international team members, foreign R&D costs still require 15-year amortization under Section 174. Make sure the platform tracks both regimes correctly.
Do you want the full picture? If you'd rather not manage separate vendors for bookkeeping, taxes, and credits, an integrated platform like Fondo keeps everything in one workflow.
