Why the state income tax is not correct

Withholding Formula (Maine Effective 2018)

1. Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
   
   
2. Subtract the nontaxable biweekly Federal Health Benefits Plan payment(s) (includes dental and vision insurance program, and flexible spending account - health care and dependent care deductions) from the amount computed in step 1.
   
   
3. Add the taxable biweekly fringe benefits (taxable life insurance, etc.) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
   
   
4. Multiply the adjusted gross biweekly wages by 26 to obtain the annual wages.
   
   
5. Determine the exemption allowance by applying the following guideline and subtract this amount from the result of step 4 to determine the taxable income.

   Exemption Allowance = $4,150 x Number of Exemptions

6. If the annualized income determined under Step 1 is $71,100 or less for a single taxpayer, the Maine standard deduction amount for withholding purposes is $8,950. If the annualized income determined under Step 1 is $142,200 or less for a married taxpayer, the Maine standard deduction amount for withholding purposes is $20,350. If annualized income determined under step 1 is $146,100 or more for a single taxpayer or $292,200 or more for a married taxpayer, the Maine standard deduction amount is $0. If the annualized income determined under Step 1 is between $71,100 and $146,100 for a single taxpayer or between $142,200 and $292,200 for a married taxpayer, calculate the Maine standard deduction amount as follows:
   Single Taxpayers
   $8,950*(($146,100 - Amount from Step 1) ÷ $75,000)
   Married Taxpayers
   $20,750*($292,200 - Amount from Step 1) ÷ $150,000)

7. Apply the taxable income computed in step 6 to the following table to determine the annual Maine income tax withholding.
