Asset location matches investments to account types—traditional, Roth, taxable—based on tax drag, growth expectations, and liquidity needs. It is the implementation layer for three-bucket policy, tax-loss harvesting, rate sensitivity, and boundary critique across modules you actually own.
1. Location Is Character
Asset location asks a different question than asset allocation: not "what do I own?" but "which legal and tax wrapper should own it?" A high-growth stock in a Roth differs from the same stock in a brokerage differs from the same stock in a pre-tax 401(k)—same ticker, different physics for return, basis, and withdrawal.
Map wrappers with boundary critique: each account is a module with its own tax rules, creditor posture, and distribution constraints.
"Allocation is strategy. Location is engineering."
2. Pre-Tax vs. Roth vs. Taxable
Pre-tax space rewards deferral: ordinary income on withdrawal, RMDs later in life, excellent for bonds and high-tax-drag assets in many plans. Roth space rewards tax-free compounding: precious for high expected growth and for assets you hope never to reflow through the IRS again. Taxable space offers basis step-up potential, loss harvesting, and flexibility—see tax-loss harvesting.
3. Rate Risk and Sequencing
Your future marginal rate is a parameter, not a prophecy. System sensitivity thinking suggests scenario-testing Roth conversions and retirement timing—not because you can forecast perfectly, but because you can bound regret.
401(k), Roth IRA, HSA, brokerage, deferred comp—each gets a row.
Yield, turnover, return type—bond coupons vs. equity appreciation vs. REIT ordinary chunks.
Often Roth for maximal tax-free compounding; often tax-deferred for high-tax ordinary income assets—personalize with counsel.
The spending bucket needs predictable refills—use three-bucket policy for rules, then place instruments so withdrawals do not spike marginal rates.
4. Employer Stock and Concentration
RSUs inside plans can silently violate your diversification story. Location plus modularity means capping employer equity and scheduling diversification without emotional market calls.
5. Structures Beyond Retail
As complexity rises, trusts and FLPs interact with location decisions. The map is not three accounts anymore; it is a system graph—draw it before you move size.
Build the lattice, not the legend.
