Is net pay the same as taxable income?

No. Taxable income is gross pay minus allowable deductions and allowances. Net pay is what remains after tax and contributions are actually deducted.

Why is my net pay different each month?

Overtime, bonuses, benefit changes, reaching an annual contribution cap, or a change of tax code can all change the deduction in a given period.

Does a higher gross salary always mean higher net pay?

Almost always, but not proportionally. Marginal tax rates and benefit phase-outs can take a large share of an increase.
