Java IRS Tax Calculation/if Else statements/Married or single

I've been tasked with creating a small IRS makeshift tax calculator. The assignments objectives to be completed are:

Write a class that prompts the user for the following information:

Filing status: Single or Married (entered as 1 for Single and 2 for Married)

Taxable income

Calculates and prints:

Filing status

Taxable income

Federal tax

I'm supposed to have specific calculations for each of the parameters, which include 0 to 27050, 27050 to 65500, and so on, which are included in the code. the real problem I'm having is that I can't seem to get the numbers to actually show up.

my code is the following:

import java.util.Scanner;
    public class P4_Icel_Murad_IRS
    {
        public static void main(String[] args){
            Scanner in = new Scanner(System.in);
            System.out.printf("Enter Marital Status: (Single = 1, Married = 2):");
            int relation = in.nextInt();
            System.out.printf("Enter taxable income:");
            int tax = in.nextInt();
            if (relation == 1){
                String status = "Single";
                if (tax <= 27050){
                    double tax2 = tax - 0.0;
                    double tax3 = (tax2 * 0.15);
                    System.out.printf(status,tax,tax3);
                }else if (27050 < tax && tax >= 65550){
                    double tax2 = (tax - 27050.0)* 0.275;
                    double tax3 = 4057.5 + tax2;
                }else if (65550 < tax && tax <= 136750){
                    double tax2 = (tax - 65550.0) * 0.305;
                    double tax3 = 14645.0 + tax2;
                }else if (136750 < tax && tax <= 297350){
                    double tax2 = (tax - 136750.0 - tax) * 0.355;
                    double tax3 = 36361.00 + tax2;
                }else if (297350 < tax && tax <= 1e100){
                    double tax2 = (tax - 297350) * 0.391;
                    double tax3 = 93374.0 + tax2;
                }
            }
                if (relation == 2){
                String status = "Married";
                if (tax <= 27050){
                    double tax2 = tax - 0.0;
                    double tax3 = (tax2 * 0.15);
                    System.out.printf(status,tax,tax3);
                }else if (27050 < tax && tax >= 65550){
                    double tax2 = (tax - 27050.0)* 0.275;
                    double tax3 = 4057.5 + tax2;
                }else if (65550 < tax && tax <= 136750){
                    double tax2 = (tax - 65550.0) * 0.305;
                    double tax3 = 14645.0 + tax2;
                }else if (136750 < tax && tax <= 297350){
                    double tax2 = (tax - 136750.0 - tax) * 0.355;
                    double tax3 = 36361.00 + tax2;
                }else if (297350 < tax && tax <= 1e100){
                    double tax2 = (tax - 297350) * 0.391;
                    double tax3 = 93374.0 + tax2;
                }
            }    

        }
    }
