from tkinter import *

class MyWindow:

    def __init__(self, win):

        self.lbl1=Label(win, text='Enter Your annual Income')

        self.lbl3=Label(win, text='Tax')

        self.t1=Entry(bd=3)

        self.t3=Entry()

        self.btn1 = Button(win, text='Tax')

        self.lbl1.place(x=50, y=50)

        self.t1.place(x=200, y=50)

        self.b1=Button(win, text='Calculate Tax', command=self.tax)

        self.b1.place(x=200, y=150)

        self.lbl3.place(x=100, y=200)

        self.t3.place(x=200, y=200)

    def tax(self):

        self.t3.delete(0, 'end')

        num1=float(self.t1.get())

        if(num1>0 and num1<=9875.00):

            Tax=(num1*10)/100

        if(num1>=9876.01 and num1<=40125.00):

            Tax=(num1*12)/100

        if(num1>=40126 and num1<=85525.00):

            Tax=(num1*22)/100

        if(num1>=85526.01 and num1<=163300.00):

            Tax=(num1*24)/100

        self.t3.insert(END, str(Tax))

window=Tk()

mywin=MyWindow(window)

window.title('Income Tax Calculator')

window.geometry("400x300+10+10")

window.mainloop()
