| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the fiscal year ended May 31, 2024, the NEOS Enhanced Income 1-3 Month T Bill ETF market value return was 5.74% and its net asset value (“NAV”) return was 5.80% compared to its reference index, the Bloomberg 1-3 Month U.S. Treasury Bill Index, which returned 5.51%. The Fund’s market value per share as of the market close of the last trading day of the reporting period was $49.80. We believe the Fund’s outperformance relative to its reference index for the reporting period is attributable to the put options overlay, which generated additional monthly income for the Fund while maintaining tax efficiency. |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? From January 30, 2024, the Fund’s inception date, through May 31, 2024, the NEOS Nasdaq-100® High Income ETF market value return was 5.72% and its net asset value (“NAV”) return was 5.75% compared to its reference index, the Nasdaq-100® Index, which returned 5.68%. The Fund’s market value per share as of the market close of the last trading day of the reporting period was $50.42. We believe the Fund’s relative outperformance during the reporting period is attributable to the active laddered call strategy utilizing NDX Index options which allowed for the underlying equities to participate with more of the upside during market moves higher and dampen the downside during months when the Nasdaq-100® Index moved lower.

The Fund’s market value per share as of the market close of the last trading day of the reporting period was $49.58. We believe the Fund’s relative underperformance during the reporting period is attributable to the active short SPX Index laddered call strategy which prevented the underlying equity portfolio from fully participating with the market upside during the sharp rally in the S&P 500® Index for specific months.
