will return an output:

 Monthly Payslip for: "Ren"
 Gross Monthly Income: $5000
 Monthly Income Tax: $500

The Tax Bracket is as follows

Salary Bracket	Rate

next 20001-40000	10%
next 40001-80000	20%
next 80001-180000	30%
180001 and above	40%

Sample Tax Computation 1

Annual Salary 60000

Salary Bracket	Rate	Taxable Amount	Total Tax
first 0 - 20000	0%	20000	0
next 20001-40000	10%	20000	2000
next 40001-80000	20%	20000	4000
next 80001-180000	30%	0	0
180001 and above	40%	0	0

Total Taxable Amount = 20000 + 20000 + 20000 = 60000

Total Annual Tax = 2000 + 4000 = 6000

Sample Tax Computation 2

Annual Salary 200000

Salary Bracket	Rate	Taxable Amount	Total Tax
first 0 - 20000	0%	20000	0
next 20001-40000	10%	20000	2000
next 40001-80000	20%	40000	8000
next 80001-180000	30%	100000	30000
180001 and above	40%	20000	8000

Total Taxable Amount = 20000 + 20000 + 40000 + 100000 + 20000 = 200000

Total Annual Tax = 2000 + 8000 + 30000 + 8000 = 48000

Sample Tax Computation 3

Annual Salary 80150

Salary Bracket	Rate	Taxable Amount	Total Tax
first 0 - 20000	0%	20000	0
next 20001-40000	10%	20000	2000
next 40001-80000	20%	40000	8000
next 80001-180000	30%	150	45
180001 and above	40%	0	0

Total Taxable Amount = 20000 + 20000 + 40000 + 150 = 80150

Total Annual Tax = 2000 + 8000 + 45 = 10045
