Step-by-Step Guide to Create a Tax Calculation Excel Sheet
Creating your own tax calculation spreadsheet for AY 2018-19 can help you understand your tax liability better. Here’s how to build one:
-
Set Up the Basic Structure:
- Create columns for different income sources (Salary, House Property, Capital Gains, etc.)
- Add rows for various deductions under Chapter VI-A
- Include a section for tax calculation based on applicable slabs
-
Income Calculation:
- Gross Salary = Basic + HRA + Special Allowance + Other Allowances
- Income from House Property = Annual Value – Municipal Taxes – 30% Standard Deduction – Home Loan Interest
- Capital Gains = Short-term + Long-term gains (with applicable exemptions)
- Other Sources = Interest Income, Dividends, etc.
-
Deductions Calculation:
- Section 80C: =MIN(Investments, 150000)
- Section 80D: =MIN(Medical_Insurance, 25000) + MIN(Parents_Insurance, 30000)
- HRA Exemption: =MIN(HRA_Received, Rent_Paid-10%_of_Basic, 50%/40%_of_Basic)
- Total Deductions = Sum of all eligible deductions
-
Taxable Income:
- = Gross Total Income – Total Deductions
-
Tax Calculation:
- Use nested IF statements to apply different tax rates based on income slabs
- Example formula:
=IF(A1<=250000,0,IF(A1<=500000,(A1-250000)*0.05,IF(A1<=1000000,25000+(A1-500000)*0.2,(A1-1000000)*0.3+125000))))
- Add 3% education cess on the calculated tax
-
Final Output:
- Display taxable income
