Introduction

Capital gains strategies combine tax rules and practical finance to increase after‑tax proceeds from asset sales. Investors and real‑estate owners commonly use three levers: timing (when you sell), installment sales (how you receive proceeds), and 1031-style exchanges or alternatives (how you reinvest). This article explains the mechanics, pros and cons, implementation steps, and IRS rules you must follow in 2025.

Why this matters now

Long‑term capital gains remain taxed at preferential rates (0%, 15%, 20%) depending on taxable income, and the 3.8% Net Investment Income Tax (NIIT) can add on at higher incomes. Short‑term gains are taxed as ordinary income. Using timing, installment sales, or like‑kind strategies correctly can lower your marginal tax rate, defer recognition, or eliminate gains in special cases (for example, the primary‑residence exclusion). See IRS guidance on capital gains and losses for details IRS – Capital Gains and Losses.

1) Timing: harvest gains when your tax rate is lower

How it works

  • Short‑term vs. long‑term: Assets held one year or less produce short‑term gains taxed at ordinary rates. Hold longer than one year to access long‑term rates.
  • Move gains into low‑income years: if you expect a lower AGI year (retirement, sabbatical, business loss year), realize gains then. Long‑term rates of 0% apply for taxpayers whose taxable income falls below the long‑term gain thresholds.

Practical steps

  • Project taxable income for the year and check the long‑term gain brackets. (FinHelp has practical guides on Timing Capital Gains to Optimize Your Marginal Tax Rate.)
  • Use tax‑lot accounting to select low‑basis lots first or use specific‑identification to minimize gains.
  • Coordinate with retirement distributions, Social Security timing, and other income to control bracket creep.

Common pitfalls

  • Ignoring NIIT (3.8%) thresholds ($200k single/$250k MFJ) may wipe out expected savings.
  • Overconcentrating in a single stock for tax reasons can increase portfolio risk.

2) Installment sales: spread gain recognition over years

How it works

An installment sale lets a seller receive payments over time and report gain proportionally as payments are received, using IRS Form 6252 to report the sale. This can prevent pushing the seller into a higher tax bracket in a single year. See IRS Form 6252 for reporting requirements Form 6252, Installment Sale Income.

When it makes sense

  • Selling privately held business assets, land, or other property where buyers will accept seller financing.
  • When the lump‑sum gain would push you into higher tax/NIIT brackets.

Key considerations

  • Interest: The IRS requires charging a minimum interest rate (applicable federal rate) on seller‑financed transactions to avoid imputed interest rules.
  • Recapture rules: For certain assets (like depreciable real property or equipment), some portion of gain attributable to depreciation may be recaptured and taxed as ordinary income up front; installment reporting may not defer all ordinary recapture.
  • Credit risk: Buyer default risk means you must evaluate creditworthiness or secure the note.

Implementation checklist

  • Draft a sale contract and promissory note with clear payment schedule and interest terms.
  • Calculate gross profit percentage and report payments on Form 6252 each year.
  • Consider a security interest or personal guarantees and consult a tax attorney for state‑law enforcement options.

3) 1031 exchanges and real‑estate alternatives

How a 1031 exchange works (real property only)

Under current law, like‑kind exchanges (commonly called 1031 exchanges) allow deferral of capital gains when investment real property is exchanged for like‑kind property held for productive use or investment. Requirements include use of a qualified intermediary, identifying replacement property within 45 days, and completing the purchase within 180 days. The IRS explains these rules in detail IRS – Like‑Kind Exchanges.

Limitations and traps

  • Post‑2017 law: 1031 treatment applies only to real property; personal‑property like‑kind exchanges no longer qualify.
  • Depreciation recapture: The portion of gain attributable to depreciation may be subject to unrecaptured Section 1250 tax (up to 25%) when you eventually sell without further deferral.
  • Use and intent: Properties held primarily for sale (flips) don’t qualify; the property must be held for investment or business use.

Alternatives and complements to 1031 exchanges

  • Delaware Statutory Trust (DST): A DST can allow fractional investment in replacement real estate that qualifies for 1031 treatment; it can simplify exchanges for passive investors.
  • Opportunity Zones (QOFs): Investing capital‑gain proceeds into a Qualified Opportunity Fund can defer gain recognition until 2026 (per the original program rules) and potentially exclude gains on the QOF investment if held ten years. See IRS Opportunity Zones guidance for program specifics IRS – Opportunity Zones.
  • Section 121 primary‑residence exclusion: For homeowners who meet ownership and use tests, up to $250k (single) or $500k (MFJ) of gain may be excluded, which can be preferable to 1031 for residences.

Practical example

A landlord sells a rental house for $500,000 with a $100,000 adjusted basis (gain $400,000). Using a 1031 to buy replacement property of equal or greater value defers the $400,000 gain. If the owner later sells without a 1031, some or all gain plus depreciation recapture will be recognized then.

4) Other strategies that interact with timing, installments, and 1031

  • Tax‑loss harvesting: Use realized losses to offset gains in the same year. This is especially useful when gains are unavoidable.
  • Gifting appreciated assets: Gifting to family in lower tax brackets can reduce tax if the recipient’s long‑term rate is lower, but beware of the gift tax rules and the carryover basis rules.
  • Charitable giving: Donating appreciated securities to a public charity avoids capital gains tax and may provide a charitable deduction. A Charitable Remainder Trust (CRT) can convert an appreciated asset into an income stream with immediate charitable income‑tax benefits but is complex.
  • Step‑up in basis at death: Assets owned at death receive a stepped‑up basis (in most cases), potentially eliminating capital gains tax at death. Estate planning should coordinate with timing and 1031 strategies.

Real‑world tradeoffs and decision checklist

  • Liquidity vs. tax deferral: 1031 exchanges defer tax but don’t provide cash to pay taxes; installment sales provide cash flow but carry buyer credit risk.
  • Compliance burden: 1031 exchanges require strict timing and use of a qualified intermediary; installment sales require careful reporting (Form 6252) and interest compliance.
  • Future tax rates and policy risk: Deferral postpones tax but not necessarily the ultimate tax burden—future rates may differ.

Step‑by‑step planning worksheet (summary)

  1. Estimate your taxable gain (sale price minus adjusted basis and selling costs).
  2. Project your taxable income and marginal tax brackets for the current and next 1–3 years.
  3. Evaluate whether a 1031, installment sale, or timing to a low‑income year can lower immediate tax.
  4. Check NIIT exposure and state capital gains rules (states may tax differently).
  5. Consult a qualified intermediary for 1031s or a tax attorney for seller financing and installment contracts.
  6. Document everything: basis records, depreciation schedules, contracts, and QI paperwork.

Common mistakes to avoid

  • Missing the 45‑day/180‑day 1031 deadlines or using proceeds directly (which defeats the exchange).
  • Failing to report installment income correctly on Form 6252.
  • Ignoring depreciation recapture when estimating the tax cost.
  • Treating tax planning in isolation from investment risk and estate planning.

Professional tips (from my practice)

  • Run a before‑and‑after cash‑flow model: look at after‑tax proceeds and the time value of deferred tax.
  • Use installment sales when you need liquidity but want to avoid a single‑year tax spike; verify buyer credit and secure collateral.
  • For 1031s, always engage an experienced qualified intermediary early and confirm that targeted replacement properties meet business‑use tests.
