Conceptual Questions
- Deduction reduces taxable income; Credit reduces tax owed directly.
Example: Deduction – student loan interest. Credit – Child Tax Credit.
A credit usually offers greater savings. - Marginal rate applies to your next dollar earned; effective rate is your total tax ÷ total income.
- Capital gains come from selling investments.
- Short-term gains (held <1 year): taxed as ordinary income
- Long-term gains (held >1 year): taxed at 0%, 15%, or 20%
- AGI is your total income minus “above-the-line” deductions.
It determines eligibility for many credits and deductions. - Bracket creep occurs when income rises with inflation but thresholds don’t, pushing you into higher tax brackets.
- Standard deduction is a fixed amount; itemizing is useful if deductions (mortgage, charity, etc.) exceed it.
- Refundable credit: can result in a refund (e.g. AOTC).
Non-refundable: only offsets tax owed (e.g. Child & Dependent Care Credit). - Freelance income is taxable. Forms include 1099-NEC or 1099-K.
- Tax software can’t correct wrong inputs. It’s only as accurate as the information you provide.
- Filing status affects your tax brackets, standard deduction, and credit eligibility.
Problem Solving Questions
- AGI = $55,000 – $2,000 – $6,500 = $46,500
- Tax Breakdown for $45,000 (Single Filer):
- First $11,000 *10% = $1,100
- Next $33,725 *12% = $4,047
- Final $275 *22% = $60.50
- Total Tax ≈ $5,207.50
- Total Itemized = $9,000 + $2,500 + $1,000 = $12,500
Standard deduction is higher → Take standard - Capital Gain = $8,500 – $5,000 = $3,500
Held > 1 year → Long-term gain taxed at 15% - Tax owed: $700 – $1,200 credit = $500 refund
- Self-employment tax = $20,000 × 15.3% = $3,060
- Head of Household gets higher deduction and lower tax brackets than single.
Benefit: lower total tax owed. - Tax owed = $3,800 – $3,200 withheld = $600 owed
- $1,000 credit saves $1,000.
$1,000 deduction in 22% bracket saves $220.
Credit is more valuable - Quarterly payment = $60,000 × 15% = $9,000 ÷ 4 = $2,250 per quarter
Interactive Challenges
- Student loan interest → Deduction
- Child Tax Credit → Credit
- IRA contribution → Deduction
- American Opportunity Credit → Credit
- $70,000 income (Single)
- Marginal tax rate: 22%
- Approximate average rate: ~14%–15%
- Take standard deduction ($13,850) → higher than itemized ($12,000)
- Sold after 8 months → Short-term gain → taxed as regular income
- IRS requires all income to be reported, even if < $600.
1099s are just one reporting tool. - Always file to avoid late filing penalty.
You can request a payment plan later. - AGI = $48,000 – $5,000 – $2,000 = $41,000
- Refund = $2,000 credit – $1,500 tax = $500 refund
