One-time lookback window

Your Company May Qualify for $50K–$600K in R&D Tax Credits

The One Big Beautiful Bill Act (July 2025) reversed §174 capitalization and reopened 2022–2024 for amended returns. If your team writes software, you probably qualify — but only until July 6, 2026.

Congress rewrote §174. You can amend.

The 2017 Tax Cuts and Jobs Act changed Section 174, forcing companies to capitalize R&D expenses over 5 years starting in 2022, instead of deducting them immediately. For SaaS companies, this quietly created a massive tax burden on engineering payroll.

On July 4, 2025, the One Big Beautiful Bill Act reversed that for domestic research. Companies can now:

  • Expense domestic R&D immediately again, starting tax year 2025
  • Amend 2022, 2023, and 2024 returns to apply the old treatment retroactively
  • Claim Section 41 credits they may have missed because of §174 confusion

The amendment window is one-time. It closes on July 6, 2026. After that, the 2022–2024 amendment path is gone for good — even if you're eligible.

If you had US engineers in 2022, 2023, or 2024, you almost certainly qualify. Section41 handles the full amended package — 6765 refiling, substantiation memo, §41 mapping — and stays on for any IRS follow-up.

Built for this window, by SaaS specialists.

SaaS-only focus

We only work with US software companies. Faster intake, tighter documentation, and none of the context-switching.

Audit-ready documentation

R&D credits require technical documentation that most generalist CPAs don't produce. Our loss rate on R&D claims is zero.

The Section41 Promise

15% contingency — nothing until you get paid. If the IRS questions any claim, we respond at our cost, now or ten years from now.

The amended-return path

Four steps, usually 30–45 days from kickoff to refund filed.

1

20-minute intake call

We confirm you qualify (US engineers in 2022–2024, filed returns for those years) and review what payroll and system data we'll need.

2

Data ingest + §41 mapping

Read-only access to GitHub, Linear, payroll. We map three years of engineering activities to the §41 four-part test.

3

CPA-signed amended package

Form 6765 plus substantiation memo plus workbook for each of 2022, 2023, 2024. Licensed CPA signs every claim.

4

File + get cash

We file (or hand to your CPA). IRS processes amended returns in 8–16 weeks. We defend for the life of the return at our cost.

Questions founders ask

Do we really have until July 6, 2026? +

Yes. The OBBBA (signed July 4, 2025) gave taxpayers one year from enactment to file amended returns for 2022–2024. After July 6, 2026, the retroactive path closes permanently.

We already filed those years. Can we still amend? +

Yes — that's the whole point. You file Form 1040-X (or 1120-X for corps) with an updated Form 6765 for each year. We handle the full package.

What if we already claimed R&D credits for those years? +

You can still benefit. The §174 reversal often unlocks additional credit that was blocked by the old capitalization rules. We run a free re-analysis to confirm.

How long until we get the cash? +

Filing: 30–45 days from engagement. IRS processing of amended returns: 8–16 weeks. Some clients see refunds in under 90 days from kickoff.

What if the IRS audits the amended return? +

We respond at our cost. Our loss rate on R&D claims is zero. The amended return path is well-established — the IRS wants these processed.

What do you charge? +

15% contingency on the refund we secure — 10% if you engage us for multi-year ongoing work. If we don't recover anything, you don't pay. No hourly fees, no minimums, no surprises.

The window closes forever

Once the amendment period closes, the 2022–2024 money is gone.

The IRS doesn't extend the lookback. Once the amendment period closes, the refunds stay with the Treasury. For SaaS companies, that's typically six-to-seven figures left on the table — permanently.
