Income

• If for some reason you have a need to keep track of your income, keeping and filing check stubs is an efficient way to do so. Some check stubs even show your total income for the year to date.
  
  

Taxes

• Paycheck stubs also display any federal, state and local taxes that were withheld from your total income. The total amount withheld depends on several factors, including marital status and any deductions you can claim.
  
  

Social Security

• Your paycheck stub should also display the total amount withheld from your income to cover Social Security and Medicare. Social Security taxes should always be withheld, even if federal and state taxes are not.
