Tax Planning
Overview
Taxes are one of the biggest expenses for solopreneurs. Without planning, you'll overpay or face penalties. With planning, you can legally minimize your tax burden and keep more of what you earn. This playbook covers tax fundamentals, quarterly payments, deductions, and strategic decisions like S-Corp election. Disclaimer: This is educational content, not professional tax advice. Consult a CPA for your specific situation.Step 1: Understand Your Tax Obligations (U.S.)
As a solopreneur, you pay multiple types of taxes. Know what you owe.
Tax types:
| Tax Type | What It Is | Rate | When You Pay | |---|---|---|---| | Income Tax | Federal tax on profit | 10-37% (marginal brackets) | Quarterly estimated + April 15 | | Self-Employment Tax | Social Security + Medicare | 15.3% on net earnings | Quarterly estimated + April 15 | | State Income Tax | State tax on profit (if applicable) | 0-13% (varies by state) | Quarterly estimated + state deadline | | Sales Tax (if selling physical goods) | Tax on sales to customers | Varies by state | Monthly or quarterly |
Total effective tax rate for solopreneurs: 25-40% of profit (depending on income level and state).
Example:
Net Profit: $100,000
Federal Income Tax (~22%): $22,000
Self-Employment Tax (15.3%): $15,300
State Income Tax (~5%): $5,000
Total Tax: $42,300 (42% effective rate)
Rule: Set aside 30% of every payment you receive for taxes. Transfer it to a separate savings account immediately.
Step 2: Make Quarterly Estimated Tax Payments
If you're self-employed, you don't have an employer withholding taxes. You must pay quarterly.
Quarterly tax deadlines (U.S.):
How much to pay each quarter:
Estimated Annual Profit Γ Effective Tax Rate / 4
Example:
Expected profit: $100,000
Effective rate: 30%
Quarterly payment: $100,000 Γ 0.30 / 4 = $7,500
How to pay:
Penalties for not paying quarterly:
Rule: Pay quarterly even if it's an estimate. Better to overpay slightly and get a refund than underpay and face penalties.
Step 3: Maximize Your Tax Deductions
Deductions reduce your taxable income. More deductions = less tax owed.
Top deductions for solopreneurs (U.S.):
1. Home Office Deduction
If you have a dedicated space for business, you can deduct a portion of rent/mortgage, utilities, insurance.Two methods:
Example:
Office: 150 sq ft
Home: 1,500 sq ft
Home expenses (rent + utilities): $24,000/year
Deduction: (150/1,500) Γ $24,000 = $2,400
Requirements:
2. Business Equipment and Supplies
Section 179 deduction: Deduct full cost of equipment in year purchased (up to ~$1M), rather than depreciating over years.
3. Vehicle and Mileage
If you drive for business (client meetings, site visits, errands):Recommendation: Use standard mileage (simpler). Track with app (MileIQ, Everlance).
Not deductible: Commuting from home to office.
4. Professional Services
5. Marketing and Advertising
6. Business Travel and Meals
Rule: Keep receipts and note the business purpose.
7. Education and Training
8. Contractor and Employee Payments
9. Health Insurance (if self-employed)
10. Retirement Contributions
Why this matters: Reduces taxable income AND builds retirement savings.
Step 4: Decide If You Should Elect S-Corp Status
If your profit is > $80-100K/year, S-Corp election can save you thousands on self-employment tax.
How S-Corp saves money:
As a sole proprietor or default LLC, you pay 15.3% self-employment tax on ALL profit.
As an S-Corp, you: 1. Pay yourself a "reasonable salary" (subject to payroll taxes) 2. Take remaining profit as "distributions" (NOT subject to self-employment tax)
Example:
Profit: $150,000DEFAULT LLC:
Self-employment tax: $150,000 Γ 15.3% = $22,950
S-CORP:
Reasonable salary: $80,000
Self-employment tax on salary: $80,000 Γ 15.3% = $12,240
Distributions (no self-employment tax): $70,000
Total self-employment tax: $12,240
SAVINGS: $22,950 - $12,240 = $10,710/year
S-Corp downsides:
When to elect S-Corp:
When NOT to elect S-Corp:
How to elect: File Form 2553 with IRS. Must be done by March 15 of the year you want it to take effect (or within 75 days of forming your LLC).
Rule: Talk to a CPA before electing S-Corp. They'll help you determine if it's worth it and set up payroll.
Step 5: Year-End Tax Planning (October-December)
The last 3 months of the year are critical for tax planning.
Year-end tax checklist:
October: Project Your Tax Liability
November: Accelerate Deductions (if profitable)
If you're having a profitable year and want to reduce taxes:Caution: Don't buy things you don't need just for the tax deduction. A deduction saves you 25-40% of the expense β you still spent the full amount.
December: Defer Income (if needed)
If you're having a very high-income year and want to spread it out:When to defer: If you're in a high tax bracket this year but expect lower income next year.
January: File Taxes (or Hire a CPA)
Step 6: Work with a CPA
When to hire a CPA:
What a CPA does:
Cost: $500-2,000/year for basic tax prep. More for complex situations or year-round advisory.
How to find a good CPA:
Red flags:
Rule: A good CPA pays for themselves in tax savings and peace of mind.
