Belgian freelance taxable income

[nodric]

Is social security and income tax both computed from the same "taxable income" figure, if you're in a freelance arrangement?

Read my post here Especially the bit on the Social Security Trap.

In short it works like this.

Social Security is assessed on your total income. This is deducted first. Tax is then calculated on the balance. i.e. SS is a deductible expense for tax computation.
