Section 174 & 174A · Brief · Intro level
Section 174A and startup cash planning
With domestic R&E expensing restored under Section 174A, most startups should simply deduct — but the 60-month capitalization election can protect NOLs from Section 382 limits, and the payroll offset stacks on top either way. A simple year-one cash view.
For tax years beginning after December 31, 2024, Section 174A — enacted in the One Big Beautiful Bill Act — lets startups deduct domestic research or experimental expenditures immediately, ending the 2022–2024 capitalization regime that generated phantom taxable income at loss-making companies. For most startups the planning answer is simple: expense. But the statute's alternative — electing to capitalize and amortize over at least 60 months — is not a trap; it is occasionally the better cash answer.
Expensing restored: the default case
A startup spending $2M on domestic engineering deducts $2M in the year spent. Foreign research — including offshore development contractors — remains capitalized over 15 years under Section 174, a distinction that matters at diligence and is unchanged by the OBBBA. Small businesses (average annual gross receipts of $31M or less) may also apply Section 174A retroactively to 2022–2024 by amended return, and all taxpayers may deduct remaining unamortized domestic 2022–2024 amounts over one or two years; Pub 538 covers the method-change framework behind these transitions.
When the 60-month election is better
Immediate deductions at a company with no income buy nothing today — they build NOLs. Two features make NOLs worth less than face value:
- The 80% limitation. Post-2017 NOLs offset only 80% of taxable income in the year used, stretching recovery.
- Section 382 exposure. An ownership change — which a priced equity round can trigger — caps annual NOL usage at roughly the company's value times a published federal rate. A startup that raises at a modest valuation after accumulating large NOLs can strand most of them.
Electing 60-month amortization under Section 174A moves the deduction out of loss years and into (hoped-for) income years, sidestepping both problems. It is the right call mainly for companies with heavy R&E spend, near-term profitability, and a financing calendar likely to trip Section 382. For everyone else, deferral is just deferral.
The payroll offset stacks either way
The Section 41 payroll offset — up to $500,000 per year against employer payroll taxes for qualified small businesses — is computed from qualified research expenses, not from the deduction method. Expense under 174A, or amortize; the credit is the same. The offset is the piece that produces cash in year one for a pre-profit company, so it should anchor the plan regardless of the 174A choice.
Year-one cash, side by side
Illustrative year one for a pre-revenue startup with $2,000,000 of domestic R&E, $1,800,000 of it wage QREs, ASC credit at 6% (no prior QREs):
| Line | Expense (174A default) | 60-month election |
|---|---|---|
| Deduction taken this year | $2,000,000 | $200,000 (half-year of $400,000/yr) |
| Current tax saved by deduction | $0 (no income) | $0 (no income) |
| NOL created | Larger | Smaller |
| Payroll offset cash (Section 41 ASC) | ~$108,000 | ~$108,000 |
| Net cash difference, year one | — | $0 |
The table's point is deliberately anticlimactic: with no taxable income, the deduction method changes year-one cash by nothing. The payroll offset — claimed via Form 8974 after the election on the original return — is the only year-one cash item. The 174A choice is entirely about later years: where the $2M deduction lands, and whether NOLs survive the cap table.
Frequently asked questions
- Can startups deduct R&D expenses again?
- Yes. Under Section 174A, enacted in the One Big Beautiful Bill Act of July 2025, domestic research or experimental expenditures are immediately deductible for tax years beginning after December 31, 2024. Foreign research remains capitalized over 15 years under Section 174. Startups may instead elect to capitalize domestic R&E and amortize it over at least 60 months.
- Why would a startup elect 60-month amortization instead of expensing R&E?
- Because a deduction a loss company cannot use today may be worth more spread into profitable years. Immediate expensing enlarges net operating losses, and NOLs are limited to 80% of taxable income when used and can be sharply restricted by Section 382 after an ownership change — common in venture financing. Amortization defers the deduction into years when it offsets actual income.
- Does expensing R&D under 174A affect the payroll tax offset?
- No — the two stack. The Section 41 research credit, and its payroll offset of up to $500,000 for qualified small businesses, is computed from qualified research expenses regardless of whether those costs are deducted immediately under Section 174A or amortized under the 60-month election. A startup can deduct everything and still convert the credit to payroll cash.
