Subsequent ordinary assessment
A subsequent ordinary assessment is the procedure that can pull a person taxed at source into an ordinary return. The pillar 3a deduction is not inside the withholding scale. It becomes concrete mainly when that assessment applies.
The wider frame is the Swiss third pillar.
