Creating an Income Tax Calculator in Google Sheets

Follow the steps below to easily create an income tax calculator in Google Sheets. 

1. List Your Income Sources and Their Amounts in Columns A and B

List your income sources in column A and their amounts in column B.

2. Sum Up Your Income in Column B to Calculate Total Income

To calculate your total income, sum the amounts in column B. If your income is listed from B2 to B4, the formula is =SUM(B2:B4).

3. Enumerate Deductible Expenses and Their Amounts in Columns D and E

In columns D and E, list your deductible expenses and their amounts, respectively.

4. Calculate Total Deductions by Summing Expenses in Column E

Sum the amounts of deductible expenses in column E. If your expenses are listed from E2 to E3, the formula is =SUM(E2:E3).

5. Compute Taxable Income by Subtracting Deductions from Total Income

Subtract total deductions from total income to find taxable income. If your total income is in B5 and total deductions are in E4, type '=B5-E4'.

6. Input Tax Brackets and Rates in a New Sheet Section

List the tax brackets and corresponding rates in a new section of the sheet.

7. Apply Tax Rates to Calculate Tax Owed Based on Taxable Income

For the simplified tax rates provided, you'll need a formula that calculates the tax based on the brackets. Here's a simplified approach to apply the correct tax rates:

‍

=IF(G2>40000, (G2-40000)*0.3 + 20000*0.2 + 20000*0.1, IF(G2>20000, (G2-20000)*0.2 + 20000*0.1, G2*0.1))

‍

Assuming G2 is your taxable income, this formula calculates the tax owed by applying the different tax rates to the income falling within each bracket.

8. Show the Calculated Total Tax Owed in a Clearly Labeled Cell

The formula above gives you the total tax owed based on the taxable income. Display this in a clear and labeled cell.

9. Ensure Accuracy by Reviewing and Testing Your Calculator

Test your calculator with different income and deduction scenarios to ensure it works as expected.
