The Effective Tax Rate is a measure that reflects the actual rate an individual pays on their overall income, considering all applicable taxes. It is calculated by dividing the total tax paid by the total income earned. This figure often varies among taxpayers even if the nominal tax rate remains the same.
In the case of Social Security tax, the effective rate shows how a higher earnings can lead to a smaller portion of income being taxed when the entire income isn't subject to the tax.
For instance, an individual earning up to the cap will have an effective tax rate equal to the nominal rate, while those exceeding the limit will experience a lower effective rate.
