Module 9: Taxes for Beginners
Understanding the Basics Without the Headache
Introduction
Welcome to Module 9! Let's talk about taxes – probably the most confusing and anxiety-inducing part of personal finance for most people.
Here's the good news: you don't need to be a tax expert. You just need to understand the basics so you can make smart decisions and keep more of your hard-earned money (legally!).
Taxes aren't just about April 15th. Understanding taxes helps you:
- Make better decisions about retirement accounts
- Maximize your refund (or minimize what you owe)
- Avoid costly mistakes
- Plan for the year ahead
In this module, we'll cover:
- How income tax actually works
- The difference between deductions and credits (big deal!)
- Tax-advantaged accounts and why they matter
- Common tax breaks you might be missing
- Filing basics – DIY or hire someone?
- Dealing with taxes if you have side income
Think of taxes as a game where the rules are published. Once you understand the rules, you can play better. Let's learn them!
Part 1: How Income Tax Works
The Tax Myth: "I'm in the 22% tax bracket"
What people think: "I pay 22% tax on all my income"
Reality: You pay different rates on different portions of your income (progressive tax system)
This is HUGE to understand.
Progressive Tax Brackets (2024 Single Filer Example)
| Taxable Income | Tax Rate | You Pay |
|---|---|---|
| $0 - $11,600 | 10% | 10% on this portion |
| $11,601 - $47,150 | 12% | 12% on this portion |
| $47,151 - $100,525 | 22% | 22% on this portion |
| $100,526 - $191,950 | 24% | 24% on this portion |
| $191,951 - $243,725 | 32% | 32% on this portion |
| $243,726 - $609,350 | 35% | 35% on this portion |
| Over $609,350 | 37% | 37% on this portion |
Example: How It Really Works
Sarah makes $60,000:
- First $11,600 taxed at 10% = $1,160
- Next $35,550 ($11,601 to $47,150) taxed at 12% = $4,266
- Next $12,850 ($47,151 to $60,000) taxed at 22% = $2,827
Total tax: $8,253
Effective tax rate: $8,253 ÷ $60,000 = 13.8%
Even though she's "in the 22% bracket," she only pays 13.8% overall!
Key Terms to Know
Gross Income:
- All income before deductions
- Salary, wages, tips, interest, etc.
Adjusted Gross Income (AGI):
- Gross income minus "above-the-line" deductions
- Examples: IRA contributions, student loan interest, HSA contributions
Taxable Income:
- AGI minus standard or itemized deductions
- This is what you actually pay taxes on
The flow: Gross Income → (minus adjustments) → AGI → (minus deductions) → Taxable Income → (apply tax brackets) → Tax Owed → (minus credits) → Final Tax Bill
💡 Exercise 9.1: Understand Your Tax Situation
From your last tax return or most recent pay stub:
My gross income: $__________
My filing status: ☐ Single ☐ Married Filing Jointly ☐ Married Filing Separately ☐ Head of Household
My federal tax bracket: ________% (highest bracket you reached)
Actual federal taxes paid: $__________
My effective tax rate: Taxes Paid ÷ Gross Income = ________%
State taxes paid: $__________
Total tax burden: Federal + State = ________%
Did you: ☐ Owe money (paid more at filing) ☐ Get a refund (got money back) ☐ Break even
If you got a big refund: You gave the government an interest-free loan. Consider adjusting withholding.
If you owed a lot: You might need to adjust withholding or make estimated payments.
Part 2: Standard Deduction vs. Itemizing
This is one of the most important tax decisions you'll make.
The Standard Deduction (2024)
What it is: Fixed amount you can deduct from income, no questions asked
Amounts:
- Single: $14,600
- Married Filing Jointly: $29,200
- Head of Household: $21,900
How it works:
- Your income: $60,000
- Standard deduction: -$14,600
- Taxable income: $45,400
- You pay taxes only on $45,400
Who should take it: About 90% of taxpayers
Itemized Deductions
What it is: Adding up specific deductible expenses
Common itemized deductions:
1. State and local taxes (SALT)
- State income taxes OR sales taxes
- Property taxes
- Cap: $10,000 total
2. Mortgage interest
- Interest on mortgage up to $750,000
- Must be on primary or second home
3. Charitable donations
- Cash donations
- Items donated (fair market value)
- Must be to qualified organizations
4. Medical expenses
- Only amount over 7.5% of AGI
- Example: If AGI is $50,000, only medical over $3,750 is deductible
5. Casualty and theft losses
- Only for federally declared disasters
- Subject to limits
Should You Itemize?
Itemize only if your itemized deductions > standard deduction
Example 1: Don't itemize
- Mortgage interest: $6,000
- Property taxes: $3,000
- Charitable donations: $2,000
- Total: $11,000
- Standard deduction: $14,600
- Take standard deduction (save $3,600 more)
Example 2: Itemize
- Mortgage interest: $18,000
- State taxes: $10,000
- Charitable donations: $5,000
- Total: $33,000
- Standard deduction: $29,200 (married)
- Itemize (save $3,800 more)
Most people take the standard deduction because it's simpler and higher than their itemized total.
💡 Exercise 9.2: Standard vs. Itemized
Estimate my itemized deductions:
| Deduction | Annual Amount |
|---|---|
| State/local taxes | $________ |
| Property taxes | $________ |
| Mortgage interest | $________ |
| Charitable donations | $________ |
| Medical (over 7.5% of AGI) | $________ |
| Other | $________ |
| TOTAL ITEMIZED | $________ |
My standard deduction: $__________ (see amounts above)
Which is larger? ☐ Standard deduction (take this one) ☐ Itemized deductions (itemize)
My savings by choosing correctly: $__________
Part 3: Tax Credits vs. Tax Deductions
CRITICAL DIFFERENCE: Credits are better than deductions!
Tax Deductions
What they do: Reduce your taxable income
Value: Depends on your tax bracket
Example:
- You're in 22% bracket
- $1,000 deduction
- Saves you: $1,000 × 22% = $220
Tax Credits
What they do: Direct reduction of taxes owed
Value: Dollar-for-dollar reduction
Example:
- $1,000 tax credit
- Saves you: $1,000 (regardless of bracket)
Credits are worth more than deductions!
Common Tax Credits
1. Earned Income Tax Credit (EITC)
- For low-to-moderate income workers
- Worth up to $7,430 (2024, with 3+ children)

Part 4: Tax-Advantaged Accounts
We covered these in Module 7, but let's look at them through a tax lens.
Pre-Tax Retirement Accounts
Traditional 401(k) and Traditional IRA:
Tax benefit NOW:
- Contributions reduce current taxable income
- Example: Earn $60,000, contribute $6,000 → taxable income $54,000
- In 22% bracket: Save $1,320 in taxes this year
Tax cost LATER:
- Pay taxes on withdrawals in retirement
- Taxed as ordinary income
Best for: High earners now, expect lower taxes in retirement
After-Tax Retirement Accounts
Roth 401(k) and Roth IRA:
Tax cost NOW:
- No deduction; pay taxes on income now
Tax benefit LATER:
- Withdrawals in retirement are TAX-FREE
- All growth is TAX-FREE
Best for: Lower earners now, expect higher taxes in retirement, want tax diversification
Health Savings Account (HSA) – The Triple Tax Advantage
The ultimate tax-advantaged account!
Benefits:
- Contributions are tax-deductible (pre-tax)
- Growth is tax-free (invest it!)
- Withdrawals for medical expenses are tax-free
Example:
- Contribute $3,850 (individual limit 2024)
- In 22% bracket: Save $847 in taxes immediately
- Invest and grow tax-free
- Use tax-free for medical expenses
- After 65, can use for anything (taxed like traditional IRA)
Requirements:
- Must have high-deductible health plan (HDHP)
Strategy: Treat as a retirement account
- Pay medical expenses out of pocket now
- Let HSA grow for decades
- Use in retirement for medical expenses (tax-free!)
💡 Exercise 9.4: Maximize Tax-Advantaged Accounts
My current contributions:
401(k):
- Current contribution: $________/year
- Maximum (2024): $23,000
- Room to contribute more: $________
IRA (Traditional or Roth):
- Current contribution: $________/year
- Maximum (2024): $7,000
- Room to contribute more: $________
HSA (if eligible):
- Current contribution: $________/year
- Maximum (2024): $4,150 individual / $8,300 family
- Room to contribute more: $________
Tax savings opportunity:
If I increased retirement contributions by $________,

And I'd have more money for retirement!
Action plan:
☐ Increase 401(k) contribution by _____% starting _______
☐ Set up automatic monthly IRA contribution of $_______

Part 5: Side Income and Taxes
Have a side hustle? Freelance? Sell things online? Here's what you need to know.
When Side Income Is Taxable
Always taxable:

Self-Employment Tax
What it is: Social Security + Medicare tax for self-employed
Rate: 15.3%
- 12.4% Social Security (on first ~$160,200)

Why so high? Employees pay 7.65%, employers pay 7.65%
- Self-employed pay both halves
Example:
- Side income: $10,000
- Self-employment tax: $1,530
- Plus regular income tax on it
Good news: Can deduct half of self-employment tax from income
Estimated Tax Payments
When required: If you'll owe $1,000+ in taxes
How it works:
- Pay quarterly (April 15, June 15, Sept 15, Jan 15)
- Estimate your tax liability

Why it matters: Avoid underpayment penalty (~6% interest)
How to estimate:

The trap: No receipts, wing it on deductions
Reality: Can't prove it = can't deduct it if audited
Fix:

Mistake #4: Math Errors
The trap: Manual calculations, rushed filing
Reality: IRS catches mistakes, sends bill with penalties
Fix: Use tax software (it does the math)

Common Questions Answered
Q: Should I aim for a refund or break even?

Q: Can I deduct crypto losses?
A: Yes, but with rules. Capital losses up to $3,000/year against ordinary income.
Q: Do I pay taxes on Venmo/PayPal for personal payments?
A: No, only business transactions. Personal gifts and reimbursements aren't taxable.

A: E-file + direct deposit: 21 days typically
Q: What if I made a mistake on filed return?
A: File amended return (Form 1040-X) within 3 years
