Problem 1

Calculate the tax liability for an individual with an income of $50,000 and deductions totaling $10,000, with a tax rate of 20%.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Taxable Income = Total Income - Deductions

Taxable Income = $50,000 - $10,000 = $40,000

Tax Liability = Taxable Income × Tax Rate

Tax Liability = $40,000 × 0.20 = $8,000

Therefore, the tax liability is $8,000.

Explanation

Subtract the deductions from the total income to find taxable income, then apply the tax rate to find the tax liability.

Problem 2

A freelancer earns $70,000 with deductions of $15,000 and a tax rate of 22%. What is the tax liability?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Taxable Income = Total Income - Deductions

Taxable Income = $70,000 - $15,000 = $55,000

Tax Liability = Taxable Income × Tax Rate

Tax Liability = $55,000 × 0.22 = $12,100

Therefore, the tax liability is $12,100.

Explanation

Calculate taxable income by subtracting deductions from income, then multiply by the tax rate for the tax liability.

Problem 3

Find the tax liability for a business with an income of $150,000, deductions of $30,000, and a tax rate of 25%.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Use the formula: Taxable Income = Total Income - Deductions

Taxable Income = $150,000 - $30,000 = $120,000

Tax Liability = Taxable Income × Tax Rate

Tax Liability = $120,000 × 0.25 = $30,000

Therefore, the tax liability is $30,000.

Explanation

Subtract deductions from total income to find taxable income, then apply the tax rate to determine the tax liability.

Tax Liability = Taxable Income × Tax Rate

Tax Liability = $70,000 × 0.18 = $12,600

Therefore, the tax liability is $12,600.

Explanation

Calculate taxable income by subtracting deductions from income, then multiply by the tax rate for the tax liability.
