Only spin-offs that tie into the main story are listed here — anthologies, fan books and the like are left out.
Sources differ by one chapter at every season break: Season 1 ends at Chapter 43 or 44, Season 2 at 94 or 95, Season 3 at 146 or 147, and Season 4 at 213 or 214. Vol. 25 opens with Chapter 214, so the start of Vol. 25 is a safe place to resume either way. The anime has no filler episodes but moves some chapters around, most visibly in Season 4. The English edition from Kodansha USA has passed 20 volumes, so Vol. 25 is not yet available in English.
Start with Season 1 from 2019. It is the beginning of the story, and every later season continues from the one before it.

Season 4 ended on September 26, 2026, and no Season 5 has been announced as of October 2026. What has been announced is a theatrical film with no date yet and the if Episode of Mafia spin-off for January 2027. The manga is still running, with 50 volumes in Japan, so there is plenty left to adapt.
Season 4 ends at the close of Iruma's first year, and the story continues in Volume 25. Sources differ on whether the last adapted chapter is 213 or 214; Volume 25 opens with Chapter 214, so starting at the beginning of that volume is safe.
