Most important take away

Bill Sweet guest-hosts for Ben Carlson, answering listener questions on tax-season topics, portfolio construction, and Social Security. The headline actionable idea is using the new “Trump accounts” as a non-deductible vehicle for kids that can be converted to a Roth IRA at age 18, plus a strong case for keeping the “safe” sleeve of a pre-retirement portfolio in short-term Treasuries rather than longer-duration bonds.

Summary

This episode is packed with actionable personal-finance insights rather than individual stock picks. The only specific security mentioned by ticker is SCHD (Schwab U.S. Dividend Equity ETF), which a viewer proposed as a bond substitute; the hosts pushed back, noting SCHD is an equity dividend ETF with far more risk than short-term Treasuries and is a different instrument entirely, not an apples-to-apples swap.

Actionable insights and advice:

1. AI and tax filing (Bill Sweet, CPA). Do not trust ChatGPT or other LLMs to prepare your tax return in 2026. Bill tested ChatGPT on the standard deduction for married filing jointly and it returned the 2024 number in 2025. LLMs do not keep up with current tax law (including the “OBBB 3” / July 4 changes referenced). For simple W-2 returns this will likely come in a few years, but complex returns with depreciation, rental property, business write-offs, etc. still need human judgment (e.g., writing off a plane to travel to rental properties or a shark as “office security” require fact-and-circumstance analysis).

2. Trump accounts vs. 529s (actionable tax/estate planning idea). If you had a child born in tax year 2025, file Form 4547 on the 2025 return to claim the $1,000 federal seed contribution — Bill calls this a “no-brainer.” Beyond the seed, Trump accounts function like non-deductible IRAs with a $5,000 annual contribution limit for kids under 18. The recommended use case: treat it as a non-deductible contribution vehicle for parents who are over the Roth IRA contribution limit, then convert to a Roth IRA at age 18 when the child has low income and therefore a low tax bill on the conversion. Bill’s illustrative math: 18 years of contributions at ~3–4% real return grows to a little over $100,000, with roughly $20,000 in conversion tax, handing an 18-year-old a Roth IRA worth about $95,000. The 5-year conversion clock means the converted basis can be accessed penalty-free after five years if needed. Key caveat: you must track basis carefully or you risk paying tax twice.

3. Investing a house down payment you no longer need for 3+ years (Sean Russo). Do not put it in “levered, illiquid private credit” (joking). Mix cash/short-term Treasuries with S&P 500. Historical data since 1871: S&P 500 is profitable in any rolling 1-month period ~57% of the time and in any rolling 3-year period ~81% of the time. Sean personally runs ~50/50 S&P 500 / cash-or-short-Treasuries for his own near-term money and suggests 50/50 to 60/40 depending on risk tolerance and whether you have dependents or steady income. Define your risk tolerance up front, because you can’t “see how it feels” partway in.

4. Bond duration for a pre-retiree’s safe sleeve (Matt Cerminaro). Viewer Jack (51, retiring in 5 years) wants his safe sleeve entirely in 3-month Treasuries after watching the 2022 rout. The data backs him up: in 2022 the 10-year Treasury total return was -17.8% (nearly a bear market, briefly hit -20% in late October) while the 3-month T-bill was +2.1%. Using a sensitivity chart, if rates rise another 300 bps, a 3-month Treasury loses only 8 bps of price while a 10-year falls roughly 20%. The actionable takeaway: if the purpose of the sleeve is to be an anchor / dry powder, stay short. Compared to a high-yield savings account, direct Treasuries have the additional advantage of being state-tax-free (in Virginia that’s 5–6% of ordinary income saved). Matt also flags that adding stocks is another way to reduce drawdown risk: historically since 1928, a 77/23 stock/T-bill mix had an average 5-year rolling return of 60% and a max 5-year drawdown of 35%, while a 60/40 (60% S&P 500 / 40% 3-month T-bills) had a 51% average 5-year return, a max drawdown of just 24%, and a 94% win rate over rolling 5-year windows.

5. Pay off the mortgage early? (Sean Russo — a “bucket” framework). Using a 4% real estate return plus the interest rate saved vs. a 9% historical stock return:

   • Mortgage rate ≤ 3.75%: “non-negotiable” — do NOT pay it off early; invest instead.
   • Mortgage rate ~3.75% to ~6.5%: gray zone; reasonable to go either way depending on age and risk tolerance.
   • Mortgage rate ≥ 7%: “non-negotiable” the other way — pay it off. Sean’s point: the “psychological dividend” of being mortgage-free is not worth forgoing an equity-like spread when your rate is very low.

6. Social Security in 2060 (Bill Sweet). FICA is effectively a flat tax up to roughly $180,000. FY 2026 is expected to raise about $720 billion in FICA, while Social Security alone nearly consumes that and Medicare adds roughly another $500 billion. Bill believes Social Security will still exist when Matt and Sean retire in the 2060s because cutting it is politically untenable. The actionable advice from Sean, channeling Nick Maggiulli: do not plan your retirement around Social Security and do not waste energy on what you can’t control — focus on raising your income (take things off your boss’s plate, side hustles, go from $60k to $120k in five years) and investing the delta.

7. Moving to NYC in your early 30s for a finance-adjacent role (Duncan, Sean, Matt). The city rewards people who show up, network, and take a shot on themselves. Frame big life decisions as the “36-year-old you” looking back, not the 27-year-old you deciding now. Warning: most NYC leases hold you liable for the full term if you break them, so a “six-month test” is harder than it sounds.

Stocks / securities mentioned: SCHD (discussed as a poor 1-for-1 substitute for bonds — it is an equity dividend ETF with meaningfully more risk). No individual stock picks were made.

Chapter Summaries

• Cold open and sponsor: Bill Sweet hosts in place of Ben Carlson; sponsor read for Betterment Advisor Solutions (automated, paperless onboarding and streamlined portfolio management for RIAs segmenting smaller accounts).
• Q1 — AI and tax filing: Bill explains why LLMs can’t yet be trusted to file returns in 2026 (hallucinated standard deductions, can’t keep up with new tax law, can’t handle nuance like depreciating a plane). Fun anecdotes: client who tried to write off a shark as office security, and another who wanted to buy a plane to depreciate it while visiting far-flung rental properties.
• Q2 — Trump accounts vs. 529s: mechanics of the new Trump accounts, $1,000 federal seed for kids born in 2025 (Form 4547), $5,000 annual contribution cap, non-deductible basis tracking, and the Roth conversion at 18 use case.
• Q3 — Investing a delayed house down payment (Sean Russo): use S&P 500 holding-period statistics to justify a 50/50 or 60/40 mix of S&P 500 and cash/short Treasuries for a 3+ year horizon.
• Q4 — Bond duration for a near-retiree (Matt Cerminaro): defends going entirely short-duration Treasuries for the safe sleeve using 2022 data and a rate-sensitivity chart; notes state-tax benefit over HYSAs; and separately shows that adding stocks (60/40) can cut 5-year max drawdown more than lengthening duration can.
• Q5 — Pay off the mortgage early? (Sean Russo): introduces a three-bucket rule (≤3.75% don’t, 3.75–6.5% your call, ≥7% pay it off); argues against paying a “psychological dividend” on a cheap mortgage.
• Q6 — Will Social Security be around in 2060? Bill walks through FICA as a flat tax, the ~$720B the program raises, and the roughly $500B Medicare adds. Sean and Matt don’t model Social Security into their own retirement plans and advise focusing on growing income instead; Bill and Duncan believe benefits will still exist but possibly be modified.
• Q7 — Moving to NYC for a finance-adjacent startup: Duncan recounts his August 2019 move (pandemic immediately followed), and Sean his drive from Denver. Consensus: the city rewards networking and extroversion, use a “future self regret” frame for the decision, and be aware NYC leases are hard to break.
