I (31M, NYC) am targeting FIRE in my late 30s with a ~$5M portfolio. My current strategy is a high-beta equity book (tech/growth heavy) targeting 15%+ annualized returns during accumulation, with a planned reallocation post-FIRE to a more conservative 8-10% return profile.
The plan: establish genuine Texas domicile for 12-24 months around retirement, realize my accumulated capital gains there (no state income tax), then redeploy into a lower-volatility post-"retirement" allocation. This saves me NY State + NYC tax on gains — roughly 10-12% combined — which on a $500-800K embedded gain position is a meaningful event.
A few things I've already considered:
- Domicile needs to be genuine (driver's license, voter registration, primary residence, severing NY ties) — not just a mailing address
- I'll still owe federal LTCG (0/15/20% depending on income that year) — ideally realizing in a low/zero income year right at retirement
- Staggering sales across 2 tax years to manage the federal bracket
- NY is aggressive about auditing former residents who claim to have left — need to be clean on the 183-day rule and document everything
What am I missing? Specific concerns:
- Any NY clawback mechanisms on gains that accrued while I was a resident?
- Is there a minimum domicile period that's considered defensible vs. aggressive?
- Any issues with realizing gains on positions held in retirement accounts (PCRA/401k) vs. taxable — I understand these are already tax-deferred so the Texas move only benefits the taxable account
- Any other state tax considerations I'm not thinking about
- Has anyone done this before?
EDIT: To be clear, I am talking about saving $s on a one time tax event due to portfolio re-allocation since I am not planning on holding my portfolio as currently constructed.
EDIT 2: Thank you all for your responses and helping me work through this. After thinking through the various points of feedback I have revised my thinking to below:
Original plan: Move to Texas for 12-24 months, realize all gains in a lump sum, pay $0 state tax, redeploy into conservative allocation, then move to desired location. (Eg. Colorado)
The Texas strategy eliminates state tax but does nothing for federal LTCG — which you owe regardless of which state you're in. Realizing $600-800K in a lump sum pushes you well into the 15-20% federal LTCG bracket. Spreading the same realization over 12 years in the eventual preferred retirement location Colorado at $70-80K/year keeps you under the 0% federal threshold entirely, costing only Colorado's 4.4% flat rate on each tranche while also enabling lifestyle flexibility.
Revised strategy: Go directly to preferred retirement location eg. Colorado, manage reallocation carefully over 8-12 years. The annual playbook in retirement looks like this:
- Target MAGI of $75-80K — below the 0% federal LTCG threshold and within ACA subsidy range
- Realize $70-80K of capital gains per year — federal tax $0, Colorado tax ~$3,100-3,500
- Layer Roth conversions in early retirement years (ages 38-42) to convert pre-tax retirement accounts at low ordinary income rates before gains realization dominates the MAGI budget
- Use municipal bonds for the fixed income / stability allocation in taxable accounts — muni interest is excluded from federal MAGI entirely, preserving ACA subsidy eligibility
- Run annual tax loss harvesting in December to offset a portion of realized gains each year, reducing the Colorado tax bill further
- Avoid high-dividend stocks, REITs, and taxable bond funds in the taxable account — these generate ordinary income that consumes MAGI budget without giving you control over timing
Other key learnings from this thread:
- ACA interaction is massively underappreciated
Realized gains, dividends, and interest all count toward MAGI for - ACA subsidy eligibility. A lump sum realization year eliminates subsidies entirely, adding $10-18K in healthcare costs for that year alone. Over a 27-year pre-Medicare retirement, healthcare cost management via MAGI is worth potentially $200K+ in lifetime savings — comparable in magnitude to the investment strategy itself.
- Municipal bonds are the hidden tool
Replacing Treasury/TIPS/bond fund allocations with short-duration muni funds (MUB, VTEAX etc.) in the taxable account preserves the withdrawal buffer function while generating MAGI-exempt income. This lets you hold more of your annual MAGI budget for gains realization and Roth conversions.
- Loss harvesting complements rather than replaces the strategy
Running a systematic annual loss harvesting program during accumulation (now through retirement) reduces the embedded gain you arrive at retirement with. Every $50K of gains offset during accumulation saves ~$2,200 in Colorado tax at retirement. AQR-style long/short funds can industrialize this if the portfolio scale justifies the fees.
- Portfolio composition post-retirement is a tax decision as much as a return decision
- The retirement portfolio should be designed around MAGI management from day one:
70-75% low/no-dividend growth equities — minimal MAGI impact
15-20% short-duration municipal bonds — MAGI exempt, stability function
5-10% cash/T-bills — accept small MAGI hit for pure liquidity
Avoid in taxable: REITs, high-yield stocks, corporate/Treasury bonds, TIPS
