Schedule · Strategy sessions
Year-end tax planning schedule.
Most year-end moves only count if they are done by December 31. These are the strategy sessions that get them planned and executed in time.
August
Mid-year coaching call
A working session to review business performance, equity events and any life changes. We re-forecast the year and move strategy items that depend on full-year visibility into early Q4.
October
Year-end projection
With extended returns filed and three quarters of actuals in hand, we project full-year income and tax, and set the target for the moves still available before December 31.
November
Year-end strategy session
Strategies that require year-end action (equity acceleration, charitable bunching, harvesting, retirement contributions) are scheduled for execution. We coordinate any signature deadlines.
By December 31
Execution
Final tax-loss harvesting, donor-advised fund contributions, charitable remainder trust funding, and year-end retirement plan contributions are completed before close of business December 31.
January 15
Close-out
The Q4 estimated payment is sized to the final numbers. IRA and HSA contributions for the year can still be made up to the April filing deadline.

17 terms
Tax terms, in plain English.
Common terms across the tax strategies, written for owners and operators rather than for examiners.
Section 1202IRC §1202
StrategyA federal exclusion that lets a non-corporate shareholder exclude some or all of the gain on the sale of Qualified Small Business Stock held more than five years. The maximum excludable gain per issuer is the greater of $10 million or ten times the taxpayer adjusted basis. For stock acquired after July 4, 2025, the cap is the greater of $15 million or 10x basis, with partial exclusions at 3 and 4 years. Earlier stock keeps the $10 million / five-year rules.
Qualified Small Business Stock (QSBS)QSBS
StrategyStock in a domestic C-corporation that meets the §1202 gross-asset and active-business tests at original issuance. QSBS status is the prerequisite for the §1202 gain exclusion and the §1045 rollover.
Section 1244IRC §1244
StrategyAllows an individual or partnership to treat a loss on the sale or worthlessness of qualifying small business corporate stock as an ordinary loss rather than a capital loss, up to $50,000 per year ($100,000 on a joint return).
Section 83(b) election§83(b)
StrategyAn election under §83 to recognize the value of restricted property at grant rather than vest. Starts the long-term capital gain holding period at grant and locks in the ordinary income amount at the grant value. Must be filed with the IRS within 30 days of grant.
Cost segregation study
StrategyAn engineering-based analysis that breaks a building into components and reclassifies short-life property out of the default 27.5 or 39-year real property schedule. The reclassified portions can then be depreciated more quickly, often eligible for bonus depreciation.
Cash balance plan
StrategyA defined-benefit retirement plan that looks like a defined-contribution plan, with hypothetical participant accounts credited annually with a pay credit and an interest credit. Funded actuarially. Often allows owner-operators to deduct contributions far above 401(k) and profit-sharing limits.
Defined-benefit planDB plan
StrategyA qualified retirement plan that promises a specific benefit at retirement, funded actuarially by the employer. Cash balance plans are a type of defined-benefit plan structured to read like a defined-contribution plan to participants.
Donor-advised fundDAF
StrategyA charitable account at a sponsoring organization that lets a donor take an immediate income tax deduction for the contribution, while distributions to charities flow out over time. Useful for bunching deductions in a high-income year.
Charitable remainder trustCRT
StrategyA split-interest trust that pays an income stream to a non-charitable beneficiary for a term of years or for life, with the remainder passing to charity. Lets an appreciated asset be sold inside the trust without immediate capital gain.
Entity optimization
StrategyThe deliberate selection and combination of legal structures (S-corp, C-corp, partnership, single-member or multi-member LLC, trust) so income, distributions, payroll and basis flow through the lowest viable tax cost.
Income shifting
StrategyThe legal redistribution of taxable income across taxpayers in a family group or across entities under common ownership so the aggregate tax bill is lower. Mechanisms include reasonable compensation to family members, family limited partnerships, and trust distributions.
Reasonable compensation
The level of wages an S-corporation must pay an owner-employee for services performed, before non-wage distributions are taken. The IRS examines reasonableness based on industry, role, hours and comparables.
Bonus depreciation
StrategyA federal provision that allows taxpayers to deduct a percentage of the cost of qualifying property in the year placed in service, rather than spreading it over the asset useful life. Permanently 100% for qualifying property acquired after January 19, 2025; earlier acquisitions follow the prior phase-down.
Qualified Business Income (QBI) deduction§199A
StrategyA deduction of up to 20 percent of qualified business income from pass-through businesses, subject to income thresholds, wage limits and specified service trade or business rules.
Passive activity loss rules§469
StrategyRules that limit deduction of losses from passive activities against non-passive income. Real estate operators who qualify as a real estate professional or who meet short-term rental tests may avoid passive treatment.
Tax planning
A process of analyzing a client’s financial situation and applying tax strategies to pay the lowest amount of taxes legally based on their facts and circumstances. Distinct from tax preparation, which is the year-end report on what already happened.
Tax preparation
The work of arranging a year of facts on the right forms and submitting the return. Preparation answers what already happened. Planning shapes what is about to happen.
