20.3 Tax Planning for Individuals: Timing of Income and Deductions, Character of Transactions, Filing Status Comparisons & Carryovers
Key Takeaways
- A cash-method individual can shift taxable income by controlling when income is received and deductions are paid, but constructive receipt prevents deferring income that is already available, and prepaid expenses generally must relate to the current year.
- Bunching itemized deductions (for example, two years of charitable gifts in one year) lets a taxpayer itemize in alternate years and take the standard deduction in the others.
- Character planning favors long-term capital gain (0%, 15%, 20%) over ordinary income, but collectibles are taxed at up to 28%, unrecaptured Section 1250 gain at up to 25%, and the sale of a business is taxed asset by asset.
- Comparing married filing jointly with married filing separately requires computing tax both ways; MFS protects against joint liability but loses many credits and deductions and compresses brackets.
- Carryovers that affect future returns include capital losses, net operating losses (80% of taxable income limit), charitable contributions (5 years), passive and at-risk losses, investment interest, the prior-year minimum tax credit (Form 8801), and negative QBI.
Why This Topic Matters
The outline's Advising domain lists several planning items that are not tied to a single form: property sales, items that affect future or past returns (carryovers), estimated tax and penalty avoidance, adjustments/deductions/credits for tax planning (timing), character of transactions, and the advantages and disadvantages of MFJ, MFS, and HOH. Exam questions present a client situation and ask for the best recommendation.
Timing Income and Deductions
Most individuals use the cash method, so the year of receipt or payment generally controls.
| Goal | Techniques | Limits |
|---|---|---|
| Defer income to a lower-rate year | Bill clients in January instead of December (self-employed); take a year-end bonus in January if the employer allows; use an installment sale; delay IRA or retirement distributions (after RMDs) | Constructive receipt: income available without restriction is taxed now; a check received December 31 is income that year |
| Accelerate deductions into a high-rate year | Pay the January mortgage payment in December; prepay state estimated tax in December (subject to the SALT cap); make charitable gifts before year-end; pay deductible medical bills | Prepaid expenses generally must relate to the current year (the 12-month rule); property tax must be assessed to be deductible |
| Bunching | Concentrate charitable gifts (for example, through a donor-advised fund) or elective medical procedures in one year | Works when itemized deductions hover near the standard deduction |
| Harvest losses | Sell investments with losses to offset gains, up to $3,000 of ordinary income | Wash sale rule for repurchases within 30 days |
| Harvest gains | Realize long-term gains in a year when taxable income stays within the 0% bracket ($48,350 single / $96,700 MFJ for 2025) | Raises AGI, which can affect credits and Social Security taxation |
| Roth conversions | Convert in low-income years (early retirement, a business loss year) | Conversion income can increase Medicare premiums and reduce credits |
Example (bunching): A married couple 60 years old has $12,000 of mortgage interest and SALT each year and gives $15,000 a year to charity, for $27,000 of itemized deductions, less than the $31,500 standard deduction. If they give $30,000 to a donor-advised fund in 2025 and nothing in 2026, they itemize $42,000 in 2025 and take the standard deduction in 2026, gaining about $10,500 of extra deductions over the two years.
Character of Transactions
The same economic gain can be taxed at very different rates:
| Transaction | Character | Maximum Federal Rate (2025) |
|---|---|---|
| Stock held more than 1 year | Long-term capital gain | 20% (+3.8% NIIT) |
| Stock held 1 year or less | Short-term capital gain | 37% |
| Collectibles (art, antiques, coins, gems, stamps, and some precious metals ETFs) held more than 1 year | 28% rate gain | 28% |
| Depreciated rental building | Unrecaptured §1250 gain / §1231 gain | 25% / 20% |
| Depreciated equipment | §1245 ordinary recapture | 37% |
| Inventory, receivables | Ordinary | 37% |
| Principal residence | Capital gain, with up to $250,000 / $500,000 excluded under §121 | 20% on excess |
Selling a business: A sole proprietorship is sold asset by asset. The purchase price is allocated among the assets (reported by buyer and seller on Form 8594): inventory and receivables produce ordinary income, equipment produces §1245 recapture, real estate produces §1231 and 25% gain, and goodwill of a self-created business is a capital asset producing long-term capital gain. A covenant not to compete is ordinary income to the seller. Planning focuses on the allocation.
Holding period planning: Waiting a few more days to pass the one-year mark can cut the rate on a large gain from 37% to 20%.
Filing Status Comparisons
| Consideration | Married Filing Jointly | Married Filing Separately | Head of Household |
|---|---|---|---|
| Tax brackets and standard deduction | Widest; $31,500 | Half of joint; $15,750; if one itemizes, the other must | Better than single; $23,625 |
| Liability | Joint and several | Each spouse liable only for own return | Separate |
| Credits lost | None | EITC (unless separated-spouse exception), education credits, student loan interest, dependent care (mostly), adoption (mostly) | None tied to status |
| Other effects | Combined income may raise phaseouts | Up to 85% of Social Security taxable if living together; IRA deduction phaseout $0-$10,000; capital loss limit $1,500 | Requires "considered unmarried" if married |
Reasons to consider MFS despite the costs include protecting a spouse from the other's tax problems (joint and several liability), lowering income-driven student loan payments, qualifying for a larger medical deduction, or keeping a refund away from a spouse's past-due debts (although injured spouse relief can also do this). A married taxpayer who lives apart from the spouse for the last 6 months and maintains a home for a child may qualify for HOH instead of MFS. The preparer should compute tax both ways, and note that a couple can switch from separate returns to a joint return within 3 years, but cannot switch from joint to separate after the due date.
Mid-Year Estimated Tax Planning
- Compare projected tax with the safe harbors: 90% of current-year tax, or 100% of prior-year tax (110% if prior-year AGI exceeded $150,000).
- A large mid-year gain or bonus can be covered by increasing wage withholding, which is treated as paid evenly through the year, rather than by a late estimated payment, which counts only when paid.
- Seasonal or lumpy income may justify the annualized income installment method (Form 2210, Schedule AI).
Items That Affect Future and Past Returns
A planner tracks every carryover so it is not lost when a client changes preparers:
| Carryover | Duration | Where Tracked |
|---|---|---|
| Capital loss | Indefinite; keeps short- or long-term character | Schedule D worksheet |
| Net operating loss (post-2017) | Indefinite; deduction limited to 80% of taxable income; generally no carryback (2-year carryback for farming losses) | Schedule 1, Line 8a |
| Charitable contributions over the AGI limits | 5 years | Schedule A worksheet |
| Passive activity losses and credits | Indefinite until disposition | Form 8582 / 8582-CR |
| Investment interest | Indefinite | Form 4952 |
| Prior-year minimum tax credit (from AMT on deferral items such as ISO exercises) | Indefinite | Form 8801 |
| Negative QBI | Indefinite; reduces future QBI | Form 8995 or 8995-A |
| Excess business loss disallowed | Becomes an NOL carryforward | Form 461 |
| Foreign tax credit | 1 year back, 10 years forward | Form 1116 |
Past returns: A client who discovers an unclaimed credit or deduction may file Form 1040-X within the refund statute (3 years from filing or 2 years from payment). An NOL from a farming loss may be carried back 2 years.
Kim, a cash-method self-employed consultant, expects to be in the 32% bracket in 2025 and the 22% bracket in 2026 because she plans to cut back her work. On December 20, 2025, she finishes a $15,000 project. Which planning step is effective?
A client plans to sell a collection of antique furniture held for 15 years at a $60,000 gain. Her ordinary income puts her in the 32% bracket. At what maximum federal rate (before the 3.8% NIIT) will the gain be taxed?
In 2024, a client exercised incentive stock options and paid $18,000 of alternative minimum tax because of the ISO spread. She is changing preparers for 2025. Which carryover must the new preparer be sure to capture?
