How the taxation works
Which regime applies depends on the Swiss canton where you work, not on the town you live in and not on the crossing nearest your home. Two people in the same town working in different cantons fall under different regimes.
Saint-Julien-en-Genevois sits in a department bordering both canton Geneva and a canton under the 1983 agreement, so both regimes are genuinely possible for its residents. Both are described below — the one that applies to you is set by your employer's canton.
If you live in Saint-Julien-en-Genevois and work in canton Geneva, the 1973 cross-border agreement applies: the Swiss employer withholds tax at source under barème A0. Geneva retrocedes 3.5% of the cross-border payroll mass to France, which grants a full tax credit — no double taxation.
If you live in Saint-Julien-en-Genevois and work in one of the eight cantons under the 1983 agreement (here Vaud, Neuchâtel, Jura or Valais), France taxes you: it taxes the full Swiss income via the annual return, with a flat-rate 10% allowance and the French progressive scale. Switzerland receives a 4.5% compensation from France in return. For the reference profile the annual tax is about €8,993.
