It’s 11:38 PM, and Luis is back at the machine shop, pulling open the bottom drawer where old prototype receipts have been sleeping since 2022. Not for nostalgia. For cash flow.
That drawer holds $31,000 in fixtures, CAD help, and failed material runs tied to a part that eventually reduced scrap on a customer order. Back then, his CPA told him the deduction had to stretch over years. Luis heard one thing: less breathing room this quarter.
Now, new Section 174A generally restores immediate expensing for domestic research or experimental costs in tax years beginning after 2024. For small manufacturers, software shops, agencies, food brands, and product businesses, that old project folder may deserve a second look.
The Tax Signal: Domestic R&E Expensing Is Back After 2024
From 2022 through 2024, many domestic research and experimental costs had to be capitalized and amortized instead of deducted right away. That hit small businesses hard because cash was already tight, and spreading deductions over time meant less near-term tax relief.
Section 174A generally brings back full expensing for domestic R&E paid or incurred in taxable years beginning after 2024. Certain eligible small-business taxpayers may also have a limited path to revisit treatment for years beginning after 2021.
That word “eligible” matters. This is not a blanket redo button. Your filing history, business size, documentation, extensions, and prior tax treatment can all affect what options are available.

Your R&D May Not Look Like a Lab
Do not let the word “research” scare you off. For Luis, R&D looked like a warped clamp, scratched parts, contractor revisions, and a final design that solved a production problem.
For a food founder like Ana, it might look like a shelf-stable salsa project: food scientist invoices, test batches, acidity changes, ingredient records, and jars that never made it to retail.
For a product business, it might be molds, samples, failed packaging, CAD revisions, usability testing, or small production runs that taught expensive lessons.
The story your CPA needs is not heroic. It is practical: What were you trying to solve? What uncertainty existed? Who worked on it? Where did the work happen? What changed after testing?
Start with a simple project list for 2022, 2023, 2024, and 2025. Use four columns: what you tried, what uncertainty existed, who worked on it, and where the work happened.
Software Counts, So Check the Invisible Drawer
For software businesses and agencies, the receipt drawer may not be a drawer at all. It may be payroll records, GitHub commits, sprint notes, cloud environments, contractor invoices, or a half-built internal tool.
Software development costs continue to sit inside the R&E framework, which means Section 174A can matter for custom apps, internal workflow tools, customer portals, quoting systems, and product code.
Think about Maya, who runs a small agency. In 2023, her team built an internal workflow dashboard because client approvals kept disappearing into email threads. It was not glamorous. It was a contractor, a clunky first version, and months of Monday complaints turning into requirements.
Not every software cost belongs in the same bucket. Ask your tax pro to separate maintenance from development. Routine bug fixes, simple updates, and technical experiments may need different treatment.
Also watch location. Foreign R&E costs generally still must be capitalized and amortized over fifteen years. If your product build included a local founder, an offshore developer, and a stateside contractor, those costs need clean separation.
Do Not File First. Model First.
The tempting move is to hear “immediate expensing” and rush toward an amended return. Slow down.
Businesses with previously capitalized domestic research costs may have options: keep amortizing, accelerate remaining amounts, or spread recovery over two tax years. The better answer depends on taxable income, state taxes, R&D credits, interest limits, net operating losses, lender covenants, owner draws, and next-year planning.
That is where small business tax strategy gets real. Luis wanted a possible refund, but he also wanted a new lathe. The bank cared about profit trends. The tax answer had to sit beside the financing answer.
Ask your CPA for side-by-side scenarios. A useful model compares taxable income before the change, deduction timing, potential refund, state impact, cash received, and next-year consequences. Results vary based on your specific situation, so the spreadsheet matters more than the headline.
Also put July 6, 2026 on your planning radar. Some summaries have flagged timing considerations for certain small-business elections tied to amended-return and method-change procedures. Do not sprint blindly, but do not ignore the clock.
Build the File Before Deadline Week
Make a folder called “R&D Review.” Inside it, create folders by year and project. Keep source documents untouched, then add a plain-English summary.
For each project, gather invoices, payroll support, contractor bills, batch notes, design files, tickets, commits, calendars, testing records, and emails that show the question you were trying to answer.
Then send your preparer sharper questions:
- Do we qualify as an eligible small-business taxpayer for retroactive Section 174A treatment on 2022 through 2024 domestic work? - Should we amend returns, file a method change, or leave prior treatment alone? - How does this interact with R&D credits, state taxes, interest limits, and net operating losses? - Should expense timing and any R&D credit study be handled together or separately?
The point is not to chase every possible deduction. The point is to stop ignoring work your business already paid for.
This week, pull the projects, sort domestic from foreign, mark software development, and book a focused tax-planning call. Bring curiosity, not certainty. That receipt drawer may be more than clutter. It may be a map of how your business learns.
