Updated for 2023, minimum wage and INSS contribution ceiling.
----------
The main advantage of the contribution is being able to guarantee a monthly benefit after certain conditions that may involve working time or even be the result of an accident at work.
CONTRIBUTION WAGE (BRL) RATE FOR INSS COLLECTION PURPOSES
up to 1,100.00 -> 7.5%
from 1,100.01 to 2,203.48 -> 9%
from 2,203.49 to 3,305.22 -> 12%
from 3,305.23 to 6,433.57 -> 14%
See how the calculation looks now for the same salary of R$ 3,000.00, which is in the 3rd range:
1st salary range: 1,100.00 x 0.075 = 82.50
2nd salary range: [2,203.48 – 1,100.00] x 0.09 = 1,103.48 x 0.09 = 99.31
Range that reaches the salary: [3,000.00 – 2,203.48] x 0.12 = 796.52 x 0.12 = 95.58
Total payable: 95.58 + 99.31 + 82.50 = 277.40
With this result, it is possible to calculate the effective rate, which is around 9.25% (277.40 ÷ 3,000.00).
