Tax Deferral Is Not the Same as Tax Avoidance

Artsmarnian warns that many popular strategies postpone taxes rather than eliminate them. Pre-tax retirement contributions, accelerated depreciation, and opportunity zones may provide valuable present-day benefits, but taxpayers must plan for the later income or recapture.

  • A deferred tax bill eventually becomes due
  • Current deductions benefit from the time value of money
  • Pre-tax 401(k) withdrawals become taxable income
  • Accelerated depreciation can create recapture on sale

“Many strategies can avoid taxes or can defer taxes, but that bill will come do at some point.”

“a tax deduction today is worth more than a tax deduction in the future”

Mandatory Roth Catch-Ups May Improve Retirement Flexibility

The episode says 2026 catch-up contributions for affected workers over 50 will be required to use Roth treatment. Although these workers may be in peak earning years and prefer pre-tax deductions, Artsmarnian argues that another tax-free bucket can provide valuable withdrawal flexibility in retirement.

  • Catch-up contributions are described as $7,500
  • Affected contributions shift from pre-tax to Roth treatment
  • Current taxes replace an immediate deduction
  • Multiple tax buckets improve future withdrawal choices

“starting next year, the catchup contributions that seventy five hundred are going to be required to be WROTH contributions.”

Bill Artsmarnian · 09:33

“Nobody ever regrets a ROTH contribution.”

The Mega Backdoor Roth and Backdoor IRA Explained

Some employer plans permit after-tax 401(k) contributions that can be converted to Roth, creating tax-free retirement assets alongside pre-tax savings. A similar backdoor IRA route may be available when the taxpayer has no pre-tax IRA balance, although eligibility and pro-rata implications require careful review.

  • Plan participants may overlook an available mega backdoor Roth feature
  • After-tax 401(k) money can potentially be converted to Roth
  • A backdoor IRA begins with an after-tax contribution
  • Existing pre-tax IRA money complicates the IRA strategy

“that megabackdoor WROTH allows you to put after tax dollars into the four to one K, convert it to WROTH, and have a nice Roth…”

Bill Artsmarnian · 07:38

“If you don't have any pre tax money in any iras, you can make after tax contributions and again convert to ROTH in the IRA”

Why an HSA Can Double as an Early-Retirement Healthcare Fund

An HSA can combine deductible contributions, investment growth, and tax-free qualified medical withdrawals. For an early retiree, accumulated HSA assets may help cover the healthcare-premium gap before Medicare eligibility, though the required high-deductible health plan is not suitable for everyone.

  • HSA eligibility requires a qualifying high-deductible plan
  • Lower premiums can improve the plan's break-even economics
  • Invested HSA balances can compound over time
  • HSA funds can support healthcare costs during early retirement

“You need to be on a high deductible plan, which isn't for everybody.”

Bill Artsmarnian · 08:18

“you have a five year gap where you need to cover probably significant healthcare premiums that HSA can be used in that case, and it's…”

The Expanded SALT Deduction Comes with a Sharp Income Phaseout

The transcript describes an increase in the state and local tax deduction limit from $10,000 to $40,000. The benefit begins phasing out above $500,000 of total income and returns to $10,000 at $600,000, creating an incentive to model flexible gains and other income around the thresholds.

  • The stated SALT ceiling rises from $10,000 to $40,000
  • The phaseout applies to both single and married filers
  • Phaseout begins above $500,000 of total income
  • The deduction returns to $10,000 at $600,000

“The new limit is forty thousand dollars.”

“Once you had six hundred thousand, you're all the way back to ten k.”

Why the New Charitable Floor Changes the Value of Small Gifts

The episode describes a 2026 floor under which the first 0.5% of adjusted gross income given to charity receives no federal deduction. It also says top-bracket taxpayers will receive deduction value at a 35% rate rather than 37%, making the timing of large deductions more consequential.

  • The charitable floor is stated as 0.5% of AGI
  • A $1 million earner's first $5,000 of gifts would provide no federal benefit
  • Top-bracket deduction value is described as capped at 35%
  • The changes can make 2025 deductions more valuable than 2026 deductions

“the first zero point five percent of your agi will not be deductible for charitable purposes.”

Bill Artsmarnian · 15:28

“They'll be treated as thirty five percent taxpayers.”

How Equity-Compensated Employees Can Time Option Income

Employees paid with company stock may have discretion over when option income is recognized. The relevant questions include how much income fits inside the current federal and state brackets and, for incentive stock options, how much can be exercised without triggering alternative minimum tax.

  • Option exercises can create flexible taxable income
  • Model both federal and state brackets
  • Incentive stock options can trigger AMT
  • Complete the analysis before making year-end exercises

“the timing of the income can often be flexible.”

“how much can we recognize without paying a MT alternative minimum tax.”

Two Small-Business Tax Levers That Require Advance Cash Planning

Small-business owners must coordinate wages with the qualified business income deduction and reserve enough cash for retirement-plan contributions. Paying insufficient wages can reduce the QBI benefit, while failing to prepare liquidity can prevent owners from using large employer and employee contribution limits.

  • QBI can provide a 20% pass-through income deduction
  • Wage limitations can reduce or eliminate QBI benefits
  • Employer and employee contributions can produce a large 401(k) total
  • Owners need cash available before applicable funding deadlines

“If you don't meet a certain wage number, that QBI benefit could be significantly reduced or even reduced down to zero if you're really screwing…”

Bill Artsmarnian · 06:14

“you have to be ready to have that cash available to fund those contributions.”
