Filing reports what already happened. Planning changes what happens, which means almost all of it has to occur before the year closes.
That timing is what separates the two, and it is why a conversation in autumn is worth more than the same conversation in spring. By filing season the facts are fixed and the return simply describes them.
This covers the strategies most commonly available to a small business, what each one depends on, the size at which each starts to pay for the administration it brings, and how to choose between them rather than attempting all of them.
Why Tax Planning Is Different from Tax Filing
Tax filing is looking backward, reporting what happened. Tax planning is looking forward, making decisions throughout the year to minimize what you legally owe. Filing a return is an exercise in reporting; planning is an exercise in strategy. The most effective strategies require action before December 31.
Pick the two or three that genuinely fit rather than attempting the whole list. Each carries administration, several only pay off above a certain size, and stacking provisions that were not designed to interact is where positions become fragile.

For cash-basis taxpayers (most small businesses), income is recognized when received and expenses are deducted when paid.
- Defer income: if you expect similar or lower income next year, delay sending December invoices until January, income shifts to next year.
- Accelerate deductions: prepay January rent, purchase supplies, pay December bonuses before year-end.
- Buy and place equipment in service by December 31 to claim Section 179 or bonus depreciation this year.
- Caution: if you expect to be in a higher bracket next year, do the opposite.
2. S-Corporation Election to Reduce SE Tax
A sole proprietor pays 15.3% SE tax on all net profit. An S-corp owner pays SE tax (FICA) only on the salary portion. Profits above salary flow as distributions, no SE tax.
- Example: $200,000 net profit. As sole proprietor: $200,000 x 92.35% x 15.3% = ~$28,249 SE tax. As S-corp with $80,000 salary: FICA on $80,000 = $12,240. Distribution $120,000, no FICA. Net saving: ~$16,009 (before CPA/payroll costs).
- Pro Tip: S-corp election makes sense when net profit consistently exceeds $50,000-$60,000/year. The IRS requires a 'reasonable compensation' salary, do not set salary artificially low.
3. Hire Family Members
Wages paid to genuine employee family members are deductible business expenses and are taxed at their (often lower) rate.
- Sole proprietors who hire their children under 18 pay no FICA or FUTA on those wages.
- The child can earn up to the standard deduction amount ($15,000 in 2025) tax-free.
- The child must actually work and be paid a reasonable market wage.
- Payments must be documented, time records, job description, checks or direct deposit.
4. Augusta Rule: Rent Your Home to Your Business (14-Day Rule)
Under Section 280A(g), if you rent your home to your business for 14 days or fewer per year, the rental income is completely tax-free to you personally, and the business gets a deduction for the rent paid.
Practical use: hold annual strategy meetings, board meetings, or team workshops at your home. Charge market-rate rent. Business deducts it; you receive it tax-free.
5. Maximize Retirement Contributions
Retirement contributions are one of the most powerful tax shelters available to small business owners:
- SEP-IRA: contribute up to 25% of net SE income, up to $69,000 (2025). Deadline is tax filing deadline including extensions.
- Solo 401(k): employee deferral $23,500 + employer contribution 25% of compensation, total up to $69,000.
- Defined Benefit (Cash Balance) Plan: for high earners, contributions can exceed $200,000/year.
6. Cost Segregation for Real Estate
If your business owns commercial real estate, a cost segregation study re-classifies components of a building from 39-year depreciable life to 5, 7, or 15 years. This front-loads depreciation deductions dramatically in early years. Typical cost of study: $5,000-$15,000; typical benefit: $50,000-$200,000 in accelerated deductions in year 1.
7. R&D Tax Credit, Broader Than You Think
The Research and Development (R&D) tax credit under Section 41 reduces your tax dollar-for-dollar, not just your income. It applies to qualifying research activities including:
- Developing new software or improving existing software
- Engineering and prototyping
- Process improvement experimentation
- New product development
Small businesses can apply up to $250,000 of R&D credit against payroll taxes (great for startups with no income tax liability yet). File Form 6765.
8. Health Reimbursement Arrangements (HRA)
A Qualified Small Employer HRA (QSEHRA) lets small businesses without group health plans reimburse employees tax-free for individual health insurance premiums and medical expenses. Annual limits: $6,350 single / $12,800 family (2025).
An Individual Coverage HRA (ICHRA) has no dollar cap and can replace group health plan coverage.
9. LIFO vs FIFO Inventory Method
For product businesses with rising inventory costs, LIFO (Last-In, First-Out) reports higher COGS (most recently purchased, more expensive goods sold first), reducing taxable profit. FIFO produces lower COGS and higher profit. The choice must be made consistently.
10. Installment Sales
When selling a business asset or the business itself, spreading the sale over multiple years (installment sale under Section 453) spreads the taxable gain across those years, potentially keeping you in lower brackets each year vs recognizing the entire gain at once.

Frequently Asked Questions
When should I implement these strategies?
Most timing strategies require action before December 31 of the tax year. Entity changes (S-corp election) typically need to be in place by March 15 for the prior year (for a new election) or by the first day of the intended tax year. Start planning in Q3, not at filing time.
How much can I realistically save?
A business owner generating $150,000-$300,000 in net profit who implements S-corp election, maximizes retirement contributions, and takes all applicable deductions can often save $15,000-$40,000 in taxes annually. Every situation is different.
Do I need a CPA for tax planning?
Not legally, but strategies like S-corp election, cost segregation, R&D credits, and defined benefit plans have complex rules with significant downside risk if done incorrectly. For most small businesses generating over $100,000 in net profit, a CPA more than pays for themselves.
How do we tell a legitimate strategy from an aggressive one?
By asking whether the arrangement would exist if there were no tax advantage, and whether the paperwork describes what actually happens. A family member genuinely working in the business at a reasonable rate is one thing; a payment with no work behind it is another, and the difference is factual rather than presentational. The same test applies to every item on the list.
Do these apply to every business?
No, and applying one that does not fit is worse than doing nothing. Each depends on facts: the entity type, the level and stability of profits, whether there are employees, whether property is involved. Some are genuinely valuable at a certain size and produce only cost and complexity below it. Work out which two or three fit your situation rather than attempting the whole list.
