Updated November 8, 2026. Quick answer: For 2027, IRS Rev. Proc. 2026-35 sets the Section 1274A ceilings at $7,704,600 for a qualified debt instrument and $5,503,300 for a cash method debt instrument, up from $7,462,600 and $5,330,500 for 2026 (Rev. Proc. 2025-32). The statute itself prints $2,800,000 and $2,000,000, and both are indexed for inflation. Under the first ceiling the discount rate used in the imputed-interest rules cannot exceed 9%, compounded semiannually; under the second, buyer and seller can jointly elect cash method interest if the other conditions are met. Both ceilings rose 3.2% (computed).
The 2027 ceilings against 2026
“For calendar year 2027, a qualified debt instrument under § 1274A(b) has stated principal that does not exceed $7,704,600, and a cash method debt instrument under § 1274A(c)(2) has stated principal that does not exceed $5,503,300.” That is item .43 of Rev. Proc. 2026-35.
| Test | Statute prints | 2026 (Rev. Proc. 2025-32) | 2027 (Rev. Proc. 2026-35) | Change |
|---|---|---|---|---|
| Qualified debt instrument, section 1274A(b) | $2,800,000 | $7,462,600 | $7,704,600 | $242,000 (computed), 3.2% |
| Cash method debt instrument, section 1274A(c)(2) | $2,000,000 | $5,330,500 | $5,503,300 | $172,800 (computed), 3.2% |
The statute indexes each of its dollar amounts for a debt instrument arising out of a sale or exchange in a calendar year after 1989, so a note from a 2027 sale is measured against the 2027 column.
What each ceiling does in a seller-financed sale
The statute gives each ceiling a different job. For a qualified debt instrument: “the discount rate used for purposes of sections 483 and 1274 shall not exceed 9 percent, compounded semiannually”.
For the cash method, the statute lists more than the dollar ceiling. Among the conditions: the note must be a qualified debt instrument whose principal is within the cash ceiling, the lender must not use an accrual method of accounting and must not be a dealer with respect to the property sold or exchanged, section 1274 must otherwise have applied, and the election must be made jointly by the borrower and lender.
Related sales are added together. Under the statute’s aggregation rule, sales that are part of the same transaction or a series of related transactions are treated as one sale or exchange, and the debt instruments arising from them as one debt instrument. Splitting one sale into several notes does not reset the test.
Which tests a note passes
Where the two dollar tests switch for a note issued in 2027, using the ceilings and one dollar over each:
| Stated principal of the note | Qualified debt instrument? | Cash method election available? |
|---|---|---|
| $5,503,300 (the cash method ceiling) | Yes | Yes, if the lender and dealer conditions are met |
| $5,503,301 (computed), the cash ceiling plus $1 | Yes | No |
| $7,704,601 (computed), the qualified ceiling plus $1 | No | No |
How the ceilings are indexed, rechecked
The statute indexes each printed dollar amount and rounds: “Any increase under the preceding sentence shall be rounded to the nearest multiple of $100 (or, if such increase is a multiple of $50, such increase shall be increased to the nearest multiple of $100).” Rev. Proc. 2026-35 prints only the results, not the inflation factor, so we tested the results instead. A ceiling printed as T could come from any factor that is at least (T minus 50) / base and below (T plus 50) / base. The two ceilings share one factor if those ranges overlap:
| Year | Factor range from the qualified ceiling (base $2,800,000) | Factor range from the cash ceiling (base $2,000,000) | Factors consistent with both (computed) |
|---|---|---|---|
| 2027 | 2.751625 to 2.751661 | 2.751625 to 2.751675 | 2.751625 to 2.751661 (overlap) |
| 2026 | 2.665196 to 2.665232 | 2.665225 to 2.665275 | 2.665225 to 2.665232 (overlap) |
The ranges overlap both years, so one inflation factor reproduces both printed ceilings. That is a consistency check on the Rev. Proc., not a re-derivation of the factor from price data.
Common mistakes
- Using the $2,800,000 or $2,000,000 printed in the statute. Those are the base amounts before inflation indexing.
- Measuring one note when the sale produced several. Notes from the same transaction are treated as one.
- Assuming the cash method applies automatically. It needs a joint election, a lender who is not on the accrual method and not a dealer in the property, and principal within the cash ceiling.
