⚠️ Important Notice: This article provides general financial education about small business structures, taxes, and retirement planning. LLC formation, S-Corp elections, quarterly tax payments, retirement plan selection, and business deductions have complex rules that vary by state, income level, business type, and individual circumstances. This is not legal, tax, accounting, or financial planning advice. Always consult with certified public accountants, tax professionals, business attorneys, and financial advisors experienced in small business before making business structure or tax decisions.
Small business ownership in America has reached historic levels with 33.2 million small businesses accounting for 46% of all private sector employment and 62.3 million employees—a testament to the entrepreneurial spirit driving the economy. Business formations are skyrocketing at a record 478,800 per month in 2025 (up 435% since 2004), yet small business owners face unique financial challenges and opportunities that traditional employment advice completely misses.
The small business financial reality presents both exceptional wealth-building potential and complex tax obligations. With 90% of net new jobs created by small businesses (2023-2024) and average small business employee wages at $33.51/hour (up 2.74%), the economic impact is undeniable. Yet the financial complexity is staggering: choosing between LLC and S-Corp can mean $10,000-$20,000+ annual tax differences, quarterly estimated tax payments required four times yearly to avoid harsh penalties, self-employment tax at 15.3% (on top of income tax!) crushing cash flow, retirement contribution limits of $70,000 (vs. W-2's $23,000!) creating massive tax-deferred wealth opportunities, and navigating deductions like the 20% QBI deduction, Section 179 expensing ($1.22 million limit 2025), and business expense strategies that can save tens of thousands.
The stakes are tremendous. Nearly 40% of small businesses carry over $100,000 in debt, yet proper tax planning and structure selection can create six-figure savings over a business's lifetime. The difference between a sole proprietor paying full self-employment tax and an S-Corp owner properly splitting salary and distributions can be $7,650-$15,300 annually on just $100,000 in net profit—$76,500-$153,000 over ten years!
Whether you're just starting a business and choosing between LLC and S-Corp, an established business owner paying too much in taxes, trying to understand quarterly estimated tax requirements, wanting to maximize retirement contributions through Solo 401(k) or SEP-IRA, or planning long-term wealth building and exit strategies, this comprehensive guide will show you exactly how to choose the right business structure to minimize taxes, calculate and pay quarterly estimated taxes correctly, maximize the 20% QBI deduction and business expense write-offs, contribute up to $70,000 annually to retirement accounts, and build substantial wealth through your business while legally minimizing tax burden.
Quick Answer: Essential Financial Information for Small Business Owners
The small business landscape (2025): 33.2 million small businesses in America (46% of private sector employment). 62.3 million employees work at small businesses. Record formations: 478,800/month (up 435% since 2004). Small businesses created 90% of net new jobs (1.2 million) March 2023-March 2024. Women own 43-47% of all small businesses (12.7M nonemployer + 1.1M employer firms). Nearly 40% carry $100K+ debt. Professional services employ 5.62M at small businesses, Construction 5.94M, Healthcare 9.26M, Accommodation/Food 8.66M.
Critical LLC vs. S-Corp decision (TAX SAVINGS!): LLC (default): All net profit subject to 15.3% self-employment tax + income tax. Example: $100K profit = $15,300 SE tax + ~$15K-$20K income tax = $30K-$35K total. S-Corp (with election): Only W-2 salary subject to 15.3% FICA. Distributions NOT subject to SE tax. Example: $100K profit split as $60K salary + $40K distribution = $9,180 FICA (employer + employee on $60K) vs. $15,300 = $6,120 SAVED annually! Over 10 years: $61,200 saved. Breakeven for S-Corp: Generally $50K-$75K net profit. Below that, administrative costs ($1,000-$3,000/year) outweigh savings.
Quarterly estimated tax obligations (AVOID PENALTIES!): Required if expect to owe $1,000+ in taxes. Due dates: April 15, June 16 (note!), September 15, January 15 (next year). Calculate using Form 1040-ES. Safe harbor: Pay 100% of prior year tax (110% if AGI $150K+) to avoid penalties. Underpayment penalty: 0.5%/month minimum, compounds. Payment methods: IRS Direct Pay, EFTPS, credit card, mail. S-Corp additional: Must run quarterly payroll, file Form 941 quarterly, pay FICA quarterly.
Retirement supercharging (MASSIVE LIMITS!): Solo 401(k): $70,000 total contribution limit 2025 ($23,500 employee deferral + up to $46,500 employer contribution), age 50+ add $7,500 catch-up, age 60-63 add $11,250 catch-up (2025) = $81,250 max! Setup deadline: December 31 for employee deferrals (S-Corp), tax filing deadline for employer portion. SEP-IRA: $70,000 limit (25% of compensation), simpler than Solo 401(k), no employee deferrals, setup deadline: Tax filing deadline + extensions. Compare: W-2 employee limited to $23,500 in 401(k)—business owners can contribute 3X more!
The 20% QBI deduction (GAME-CHANGER!): Qualified Business Income deduction: Deduct 20% of qualified business income. Made permanent by One Big Beautiful Bill Act (2025). Income limits for full deduction: $197,300 single, $394,600 married filing jointly (2025). Above limits: Phase-outs apply, especially for "specified service trades" (health, law, accounting, consulting, financial). Example: $150K QBI → $30,000 deduction → Save $6,600-$11,100 in taxes (22-37% bracket). NEW 2026: Minimum $400 deduction for taxpayers with $1,000+ QBI.
Biggest misconceptions debunked: "LLCs pay less tax than S-Corps" → WRONG—LLC is legal structure, S-Corp is tax election. LLCs can elect S-Corp status! "Quarterly taxes are optional" → NO—harsh penalties compound, IRS doesn't forget. "Solo 401(k)s are complicated" → Actually simpler than you think, worth it for $70K contribution limit. "I can deduct anything as business expense" → Only "ordinary and necessary" expenses, IRS audits aggressive deductions.

Understanding Business Structures: LLC vs. S-Corp Tax Comparison
The single most impactful financial decision for small business owners is choosing—or switching to—the right tax structure.
Business Structure Basics
Four main types:
1. Sole Proprietorship (no formation required):
- Simplest structure, no formal filing
- Report on Schedule C (Form 1040)
- No liability protection (personal assets at risk)
- All profit subject to self-employment tax (15.3%)
2. Partnership (2+ owners):
- File Form 1065, issue K-1s to partners
- Active partners pay SE tax on their share
- Partnership agreement defines profit splits
- Pass-through taxation
3. LLC (Limited Liability Company):
- State-level formation ($50-$500 fees)
- Liability protection (personal assets separate)
- Can be taxed as: sole proprietor (single-member), partnership (multi-member), S-Corp, or C-Corp (by election)
- Default: Pass-through taxation with SE tax on all profit
4. Corporation (C-Corp or S-Corp):
- C-Corp: Separate tax entity, pays 21% corporate rate, double taxation (corporate + dividends)
- S-Corp: Pass-through taxation, owners pay on personal returns
- S-Corp KEY: Only W-2 salary subject to SE/FICA tax, distributions are NOT
Critical understanding: LLC is a LEGAL structure. S-Corp is a TAX election. You can have an LLC taxed as an S-Corp—best of both worlds!
The Self-Employment Tax Reality
Self-Employment Tax = 15.3%:
- Social Security: 12.4% (on first $176,100 in 2025)
- Medicare: 2.9% (on ALL earnings)
- Additional Medicare: 0.9% (on earnings over $200K single/$250K married)
Who pays it:
- Sole proprietors: On ALL net profit
- Partners: On active partner share
- LLC members (default): On ALL profit
- S-Corp owners: Only on W-2 salary (NOT distributions!)
Example comparison:
$100,000 net business profit:
As sole proprietor/LLC (default):
- SE tax: $100,000 × 15.3% = $15,300
- Plus income tax: ~$15,000-$22,000 (depending on deductions/bracket)
- Total tax: $30,300-$37,300
As S-Corp (proper salary/distribution split):
- W-2 salary: $60,000
- Distribution: $40,000
- FICA on salary: $60,000 × 15.3% = $9,180 (split employer/employee)
- SE tax on distribution: $0
- Income tax: ~$15,000-$22,000 (same)
- Total tax: $24,180-$31,180
Tax savings: $6,120 annually!
Over 10 years: $61,200 saved from S-Corp election alone.
When to Choose S-Corp Over LLC
S-Corp makes sense when:
- Net profit consistently $50,000-$75,000+
- Willing to run payroll (costs $500-$1,500/year)
- Can pay "reasonable" W-2 salary
- Business profitable and stable
S-Corp breakeven analysis:
Annual costs:
- Payroll processing: $500-$1,500
- Tax prep (more complex): $500-$1,000 extra
- State S-Corp fees: $0-$800 (varies by state)
- Total annual cost: $1,000-$3,300
Tax savings on $100K profit: $6,120
Net benefit: $2,820-$5,120
On $50,000 profit:
- Tax savings: ~$3,060 (at reasonable salary split)
- Annual costs: $1,000-$3,300
- Net benefit: -$240 to +$2,060 (barely worth it at low end)
On $150,000 profit:
- Tax savings: ~$9,180-$12,000 (depending on salary split)
- Annual costs: $1,000-$3,300
- Net benefit: $5,880-$11,000 (absolutely worth it!)
Rule of thumb: S-Corp beneficial at $60K+ net profit
Reasonable Compensation Requirement
IRS mandate: S-Corp owners must pay themselves "reasonable" W-2 salary before taking distributions.
What's "reasonable":
- Industry standards for similar work
- Your qualifications/experience
- Time devoted to business
- Business size and complexity
- Comparable salaries in your area
Red flag salary splits to AVOID:
- $100K profit: $20K salary/$80K distribution (too low!)
- $100K profit: $90K salary/$10K distribution (defeats purpose)
Safe salary ranges (general guidelines):
- $50K profit: $30K-$35K salary (60-70%)
- $100K profit: $50K-$70K salary (50-70%)
- $200K profit: $80K-$130K salary (40-65%)
- $500K profit: $150K-$300K salary (30-60%)
Higher profits allow lower percentages (but not too low!).
IRS scrutiny: They audit aggressive splits. Reasonable compensation supported by industry data is defendable.

Quarterly Estimated Taxes: Staying Compliant and Avoiding Penalties
One of the biggest shocks for new business owners is quarterly estimated tax requirements.
Who Must Pay Quarterly Taxes
You're required to pay quarterly if:
- Expect to owe $1,000+ in taxes for the year
- Don't have taxes withheld from another job covering your business income
- Are self-employed (sole proprietor, partner, S-Corp owner)
Example triggering quarterly requirement:
- Net business profit: $30,000
- SE tax: $4,590
- Income tax: ~$3,000-$5,000
- Total owed: $7,590-$9,590 (well over $1,000!)
Quarterly Payment Due Dates (MEMORIZE THESE!)
2025 quarterly deadlines:
Q1: January 1 - March 31 → Due April 15, 2025
Q2: April 1 - May 31 → Due June 16, 2025 (note: not June 15!)
Q3: June 1 - August 31 → Due September 15, 2025
Q4: September 1 - December 31 → Due January 15, 2026
If due date falls on weekend/holiday: Next business day.
Critical note: Q2 and Q3 are NOT equal quarters! Q2 is only 2 months, Q3 is 3 months.
Calculating Quarterly Estimated Taxes
Method 1: Pay 100% of Prior Year Tax (Safe Harbor)
Easiest method to avoid penalties:
- Look at 2024 tax return, line 24 (total tax)
- Divide by 4
- Pay that amount each quarter
- No penalty even if 2025 income is higher!
Exception: If AGI $150,000+ (married) or $75,000+ (single), must pay 110% of prior year tax.
Example:
- 2024 total tax: $20,000
- 2025 quarterly payment: $20,000 ÷ 4 = $5,000
- Pay $5,000 each quarter, avoid penalty
Method 2: Pay 90% of Current Year Tax
If income dropped or more accurate:
- Estimate 2025 total tax
- Pay 90% of estimated amount divided by 4
- More complex but can lower payments if income decreased
Method 3: Annualized Income Method
For highly variable income:
- Calculate actual income each quarter
- Pay tax only on that quarter's income
- Complex, uses Form 2210 Schedule AI
- Best for seasonal businesses
Underpayment Penalties
Penalty rate: Federal short-term interest rate + 3% (typically 5-8% annually)
Penalty structure: 0.5% per month minimum on underpaid amount
It compounds: Penalty accrues monthly until paid
Example penalty:
- Required quarterly payment: $5,000
- You paid: $0
- Penalty for 3 months (until next quarter): $5,000 × 0.5% × 3 = $75
- This repeats and compounds if you keep missing payments
Annual underpayment on $20,000:
If you paid nothing quarterly and owe $20,000 at tax time:
- Penalty: ~$500-$1,000 depending on timing
- Avoidable by paying quarterly!
Payment Methods
1. IRS Direct Pay (Free):
- Pay directly from checking/savings
- IRS.gov/payments
- Immediate confirmation
2. EFTPS (Electronic Federal Tax Payment System):
- Free enrollment
- Schedule payments in advance
- Track payment history
- Best for recurring quarterly payments
3. Credit Card:
- Processors charge 1.85-1.99% fee
- Earn rewards points (if >2% back, net positive)
- Convenience fee: $50K payment = $925-$995 fee
4. Mail Check:
- Send with Form 1040-ES voucher
- Mail 7-10 days before due date
- Certified mail recommended (proof)
Pro tip: Set up EFTPS, schedule all 4 quarters in January. Never miss a deadline.
S-Corp Quarterly Obligations
Additional requirements for S-Corps:
1. Quarterly Payroll:
- Must run payroll at least quarterly (monthly better)
- Withhold employee portion FICA (7.65%)
- Pay employer portion FICA (7.65%)
- Pay withheld income tax
2. Form 941 (Quarterly):
- Report wages paid and taxes withheld
- Due last day of month following quarter end
- Q1: April 30, Q2: July 31, Q3: October 31, Q4: January 31
3. State Quarterly Taxes:
- Most states require quarterly unemployment tax
- Some states have quarterly income tax withholding
- Varies by state
Total S-Corp quarterly compliance:
- Federal estimated taxes (owner's share)
- Payroll taxes (FICA + withholding)
- Form 941 filing
- State obligations
- This is why S-Corp costs $1,000-$3,000/year in admin!
Maximizing Retirement Contributions: Solo 401(k) and SEP-IRA
Small business owners have access to the HIGHEST retirement contribution limits available—3X what W-2 employees get!
Solo 401(k): The Powerhouse for Owner-Only Businesses
Contribution limits (2025):
Employee deferral: $23,500 (under 50)
Catch-up (50-59 or 64+): +$7,500 = $31,000
Catch-up (60-63): +$11,250 = $34,750
Employer contribution: Up to 25% of compensation
Total maximum: $70,000 (under 50), $77,500 (50-59 or 64+), $81,250 (60-63)
Dual contribution sources:
As employee, you defer salary:
- Max $23,500 (2025)
- Pre-tax or Roth option
- Reduces current taxable income (if pre-tax)
As employer, your business contributes:
- Up to 25% of W-2 compensation (S-Corp)
- Up to 20% of net self-employment income (sole proprietor)
- Tax-deductible business expense
Example (S-Corp with $150K profit):
Owner takes $90K salary:
- Employee deferral: $23,500
- Employer contribution: $90,000 × 25% = $22,500
- Total contribution: $46,000
- If age 52: Add $7,500 catch-up = $53,500 total!
Example (Sole proprietor with $150K net profit):
Calculation more complex (must account for SE tax deduction):
- Net earnings after SE tax deduction: ~$139,000
- Employee deferral: $23,500
- Employer contribution: ~$27,800 (20% of adjusted earnings)
- Total contribution: ~$51,300
SEP-IRA: Simpler Alternative
Contribution limit (2025): $70,000 or 25% of compensation (whichever is less)
Key differences from Solo 401(k):
Advantages:
- Simpler to set up and maintain
- No annual filings (unless assets >$250K)
- Can be established by tax deadline + extensions
- Lower administrative burden
Disadvantages:
- NO employee deferrals (only employer contributions)
- Can't contribute as much on same income
- No Roth option
- If you have employees, must contribute same % for them
Example comparison (sole proprietor, $150K net profit):
Solo 401(k):
- Employee: $23,500
- Employer: $27,800
- Total: $51,300
SEP-IRA:
- Only employer: $27,800
- Total: $27,800
Difference: $23,500 LESS with SEP-IRA!
When SEP-IRA makes sense:
- Lower income (<$100K) where difference is small
- Want simplicity over max contribution
- Established late in year (can setup by April 15 + extensions)
- Have employees and willing to contribute for them
Setup Deadlines (CRITICAL!)
Solo 401(k):
For employee deferrals:
- S-Corp: Must establish by December 31 of tax year
- Sole proprietor: Must establish by December 31 of tax year
- Can't defer salary retroactively!
For employer contributions:
- Can fund until business tax return deadline + extensions
- S-Corp/LLC: March 15 + extensions (September 15)
- Sole proprietor: April 15 + extensions (October 15)
SEP-IRA:
- Can establish AND fund by tax return deadline + extensions
- Much more flexible timing
- Good for tax year 2025 discovered in March 2026 you want to contribute
The Tax Benefits Are Massive
Example: S-Corp owner, $200K profit, age 52:
Contribution:
- Salary: $120,000
- Employee deferral: $23,500
- Catch-up: $7,500
- Employer: $30,000 (25% of $120K)
- Total: $61,000
Tax savings:
- Federal income tax saved (24% bracket): $14,640
- State tax saved (5% avg): $3,050
- First-year tax savings: $17,690
Over 30 years (7% growth):
- Total contributed: $1,830,000
- Account value: $5,800,000+
- Tax-deferred growth: $3,970,000+
Compare to W-2 employee limited to $31,000/year—business owner contributes DOUBLE and builds DOUBLE the wealth!
Choosing Between Solo 401(k) and SEP-IRA
Choose Solo 401(k) if:
- Want maximum contributions
- Income $100,000+
- No employees (or only spouse)
- Want Roth option
- Willing to handle extra admin
Choose SEP-IRA if:
- Income <$100,000 (difference small)
- Want simplicity
- Established business late in year
- May hire employees later
- Lower admin tolerance
Pro tip: Most high-earning business owners choose Solo 401(k) for the extra $23,500 employee deferral capacity.

Business Tax Deductions: The 20% QBI Deduction and Beyond
Strategic use of deductions can save small business owners $10,000-$50,000+ annually.
The 20% Qualified Business Income (QBI) Deduction
What it is: Deduct 20% of qualified business income from taxable income (NOT from gross income).
Made permanent: One Big Beautiful Bill Act (2025) made QBI deduction permanent (was set to expire end of 2025).
Who qualifies:
- Sole proprietors
- Partnerships
- S-Corporations
- LLCs (taxed as pass-through)
Income limits for full deduction (2025):
- Single: $197,300
- Married filing jointly: $394,600
Above limits: Phase-outs begin, especially for "specified service trades."
Specified service trades (restricted at high incomes):
- Health, law, accounting, actuarial science
- Performing arts, consulting, athletics
- Financial services, brokerage, investing
- Any trade where principal asset is reputation or skill of employees
Example calculation:
Business owner (non-specified service), single, $150K QBI:
- QBI deduction: $150,000 × 20% = $30,000
- Taxable income reduced by $30,000
- Tax savings (24% bracket): $7,200
- Tax savings (32% bracket): $9,600
- Tax savings (37% bracket): $11,100
This is IN ADDITION to normal business deductions!
NEW for 2026: Minimum $400 deduction for taxpayers with at least $1,000 in qualified business income (helps very small businesses).
Section 179 Expensing: Write Off Equipment Immediately
What it is: Deduct full cost of qualifying business property/equipment in year purchased (instead of depreciating over years).
2025 limits:
- Maximum deduction: $1.22 million
- Phase-out begins: $3.05 million in purchases
Qualifying property:
- Machinery, equipment
- Computers, software
- Office furniture
- Business vehicles (with limits)
- Some real estate improvements
Example:
Purchase $50,000 in equipment in 2025:
With Section 179:
- Deduct full $50,000 in 2025
- Tax savings (24% bracket): $12,000 immediately
Without Section 179 (normal depreciation):
- Deduct ~$10,000/year for 5 years
- Tax savings: $2,400/year
- Miss $12,000 - $2,400 = $9,600 in time value!
Bonus depreciation: NEW 100% bonus depreciation (effective for property acquired after January 19, 2025) allows write-off of 100% of eligible property beyond Section 179 limits.
Common Business Deductions (Don't Miss These!)
Home office deduction:
- Simplified: $5/sq ft, max 300 sq ft = $1,500
- Actual expense: Percentage of home costs (mortgage interest, utilities, insurance, repairs)
- Must be used regularly and exclusively for business
- Example: 200 sq ft office in 2,000 sq ft home = 10% of home costs deductible
Vehicle expenses (2025):
- Standard mileage: $0.70/mile
- Actual expense: Gas, insurance, maintenance, depreciation (requires detailed records)
- Example: 10,000 business miles × $0.70 = $7,000 deduction
Health insurance:
- Self-employed: 100% of premiums deductible above-the-line
- Includes spouse and dependents
- Must show net profit
- Example: $15,000/year premiums = $15,000 deduction = $3,600-$5,550 tax savings
Business meals:
- Client meetings: 50% deductible
- Office snacks/meals: 50% deductible
- Business travel meals: 50% deductible
- Keep receipts and document business purpose!
Startup costs:
- Up to $5,000 deductible first year
- Remaining amortized over 180 months
- Organizational costs: Legal, accounting for formation
- Example: $8,000 startup costs → $5,000 year 1 + $20/month for 150 months
Professional development:
- Courses, seminars, conferences
- Books, subscriptions related to business
- Must maintain or improve skills for current business
- Example: $3,000 in courses = $720-$1,110 tax savings
Retirement contributions:
- Solo 401(k) employer contributions: Fully deductible
- SEP-IRA contributions: Fully deductible
- Example: $30,000 contribution = $7,200-$11,100 tax savings
Cash Flow Management for Small Businesses
Managing irregular income and expenses is critical for survival.
The Business Emergency Fund
Target: 6-12 months of business expenses
NOT revenue—expenses (payroll, rent, utilities, inventory).
Why more than personal emergency fund:
- Client payment delays
- Seasonal revenue fluctuations
- Unexpected equipment failures
- Economic downturns
- Loss of major client
Building strategy:
- 10-20% of revenue to savings account
- Separate business savings from operating account
- High-yield business savings (4-5% APY)
- Don't touch except true emergencies
Example:
- Monthly expenses: $15,000
- Target emergency fund: $90,000-$180,000
- Seems like a lot, but it's survival insurance
Separating Business and Personal Finances
Critical for LLC/S-Corp liability protection:
- Separate business checking account
- Business credit card (not personal)
- Pay yourself a salary (S-Corp required, LLC recommended)
- NEVER commingle funds
Commingling risks:
- Piercing corporate veil (lose liability protection)
- Tax audit red flag
- Can't track true business profitability
- Disaster for bookkeeping
Paying Yourself as Business Owner
S-Corp (required):
- Set reasonable salary
- Run payroll at least quarterly
- Pay yourself via W-2
- Take distributions on top (as profit allows)
LLC/Sole proprietor (recommended):
- Set "owner's draw" amount
- Transfer monthly like salary
- Helps budgeting and separation
- Example: $5,000/month draw regardless of revenue fluctuations
Don't:
- Take random amounts whenever
- Leave all money in business account
- Pay personal expenses from business account
Pricing for Profitability
Cost-plus pricing:
- Calculate all costs (labor, materials, overhead)
- Add desired profit margin (20-50%+)
- Example: $100 cost + 40% margin = $140 price
Value-based pricing:
- Charge based on value delivered (not hours)
- Higher margins for specialized expertise
- Example: $500 service costs $100 to deliver but saves client $5,000
Common pricing mistakes:
- Forgetting to include your salary
- Undervaluing your time
- Not accounting for taxes (15.3% SE tax + income tax!)
- Not raising prices with experience/value
Long-Term Wealth Building and Exit Planning
Small business ownership is the path to building substantial wealth—if done strategically.
Building Business Value for Sale
Businesses sell for 2-5× annual profit (varies by industry):
Example:
- Net profit: $200,000/year
- Sale multiple: 3×
- Sale price: $600,000
Increasing sale value:
- Consistent, growing revenue (3-5 year track record)
- Diversified client base (not dependent on 1-2 clients)
- Documented systems/processes (not dependent on you)
- Strong team (business runs without owner)
- Clean financials (proper bookkeeping, separate accounts)
- Intellectual property (trademarks, patents, customer lists)
Prepare 2-3 years before planned sale:
- Maximize profitability
- Clean up balance sheet
- Document everything
- Make business owner-independent
The QSBS (Qualified Small Business Stock) Opportunity
For C-Corporation owners only:
If you hold C-Corp stock for 5+ years, can exclude capital gains from federal tax up to greater of:
- $10 million, OR
- 10× your investment basis
Requirements:
- Must be C-Corporation
- Gross assets under $50 million at issuance
- Active business (not passive investing)
- Acquired stock at original issue
Example:
- Invest $100,000 founding C-Corp
- Sell 10 years later for $15 million
- Normally owe: ~$3 million in capital gains tax
- With QSBS: $0 federal tax (full $15M excluded!)
Catch: Most small businesses are LLCs/S-Corps. Must convert to C-Corp and hold 5 years.
Succession Planning Options
1. Sell to third party:
- Maximum value typically
- Broker fees: 10-15% of sale
- Timeline: 6-18 months average
2. Sell to employees (ESOP):
- Employee Stock Ownership Plan
- Tax advantages for seller
- Keeps business in employees' hands
- Complex, requires valuation
3. Family succession:
- Transfer to children/family
- Estate planning considerations
- Avoid family conflict with clear agreements
- May not maximize value
4. Liquidation:
- Close business, sell assets
- Lowest value typically
- Last resort if no buyer
Wealth Extraction Strategies
While running business:
- Maximize retirement contributions ($70K/year)
- Take S-Corp distributions (no SE tax)
- Invest personal savings in index funds
- Build personal portfolio outside business
At exit:
- Seller financing: Spread gain over years
- Installment sale: Pay capital gains over time
- Asset sale vs. stock sale (tax implications)
- Qualified Small Business Stock exclusion (C-Corps)
Diversification is key:
Don't have 100% net worth in business—too risky. Target 50% in business, 50% in other investments by exit.
Frequently Asked Questions
Should I form an LLC or elect S-Corp status?
Start with LLC for simplicity and liability protection. Once net profit reaches $50,000-$75,000, elect S-Corp status (file Form 2553) to save $3,000-$6,000+ annually in self-employment taxes. Can have LLC taxed as S-Corp—best of both worlds. Below $50K profit, administrative costs outweigh tax savings.
Do I really need to pay quarterly estimated taxes?
Yes, if you expect to owe $1,000+ for the year. Penalties for underpayment accrue monthly at 0.5%+ and compound. Safe harbor: Pay 100% of prior year's tax (110% if AGI $150K+) divided into 4 quarterly payments to avoid penalties even if current year income is higher.
What's a "reasonable" S-Corp salary?
Industry standard for similar work, considering your experience, time devoted, and business size. Generally 40-70% of net profit depending on profit level. Higher profits allow lower percentages. Red flags: Too low (<30% of profit) or defeats purpose (>80% of profit). Document rationale with industry salary data.
Should I choose Solo 401(k) or SEP-IRA?
Solo 401(k) if income $100,000+ and want maximum contributions—allows employee deferrals ($23,500) PLUS employer contributions (up to total $70,000). SEP-IRA if want simplicity, income under $100K, or established business late in year—only employer contributions (up to $70,000) but easier administration.
How do I maximize the 20% QBI deduction?
Ensure business structure is pass-through (LLC, S-Corp, partnership, sole proprietor). Keep taxable income under $197,300 single/$394,600 joint for full deduction. For specified service trades above limits, consider strategies like spousal employment, retirement contributions, and timing income/deductions to stay below phase-out thresholds.
Can I deduct my home office?
Yes, if space is used regularly and exclusively for business. Simplified method: $5/sq ft up to 300 sq ft ($1,500 max). Actual expense method: Percentage of home costs (potentially higher deduction but requires detailed records). Choose method that maximizes deduction while maintaining accurate documentation.
What business expenses can I deduct?
"Ordinary and necessary" expenses for your trade/business: office supplies, equipment (Section 179!), vehicle mileage ($0.70/mile), business meals (50%), client entertainment (limited), professional development, software/subscriptions, legal/accounting fees, marketing, insurance, rent, utilities (if dedicated space), health insurance premiums (self-employed), retirement contributions. Keep receipts and document business purpose!
