Hi Auralia Malik, you can use the packages tax-calculation 0.6.8 in your python code library. then you can find the calculation of taxes as per country and as per state. Below i have done this code in cloud-tax calculation-:

 import copy
import numpy as np
import taxcalc 0.6.8
from .utils import *
from .functions import *
from .policy import Policy
from .records import Records
from .behavior import Behavior
from .growth import Growth
from .consumption import Consumption

class Calculator(object):
    """
    Constructor for the Calculator class.
    Parameters
    ----------
    policy: Policy class object
        this argument must be specified
        IMPORTANT NOTE: never pass the same Policy object to more than one
                        Calculator.  In other words, when specifying more
                        than one Calculator object, do this:
                        pol1 = Policy()
                        rec1 = Records()
                        calc1 = Calculator(policy=pol1, records=rec1)
                        pol2 = Policy()
                        rec2 = Records()
                        calc2 = Calculator(policy=pol2, records=rec2)
    records: Records class object
        this argument must be specified
        IMPORTANT NOTE: never pass the same Records object to more than one
                        Calculator.  In other words, when specifying more
                        than one Calculator object, do this:
                        pol1 = Policy()
                        rec1 = Records()
                        calc1 = Calculator(policy=pol1, records=rec1)
                        pol2 = Policy()
                        rec2 = Records()
                        calc2 = Calculator(policy=pol2, records=rec2)
    verbose: boolean
        specifies whether or not to write to stdout data-loaded and
        data-extrapolated progress reports; default value is true.
    sync_years: boolean
        specifies whether or not to syncronize policy year and records year;
        default value is true.
    behavior: Behavior class object
        specifies behaviorial responses used by Calculator; default is None,
        which implies no behavioral responses.
    growth: Growth class object
        specifies economic growth assumptions used by Calculator; default is
        None, which implies use of standard economic growth assumptions.
    consumption: Consumption class object
        specifies consumption response assumptions used to calculate
        "effective" marginal tax rates; default is None, which implies
        no consumption responses.
    Raises
    ------
    ValueError:
        if parameters are not the appropriate type.

If you are calculate this type tax then you easily manage the tax. and divide tax into many part as par your requirement.

Following these step given below
1- First we go to account module account -> configuration -> accounting ->Taxes and create tax as given below screen shoot
2- If you developer then you manage and chage account_tax function in .py file in
account module.
