US State Tax Calculation on 10 Months annualized factor instead of 12 Months

We are working for a Public Sector client for whom the Employees are paid with Monthly pay frequency on 10 Month Salary basis. While running the payroll calculation for those employees we found that the state taxes are calculating on an annualized tax calculation method which takes 12 months to derive the annualized salary and calculates the taxes on that. Is there a way we can get the annualized tax calculation method to calculate annualized salary based on 10 Months taxable gross instead of 12 months.
