The 351 tax loophole (based on IRS Section 351(a)) allows investors to transfer highly appreciated assets, such as stocks or real estate, into a corporation or ETF in exchange for shares without triggering immediate capital gains taxes. By doing this, wealthy investors defer or potentially avoid paying taxes on the gains while diversifying their portfolios.
In this post, we elaborate on what we see as the biggest risks with 351 exchanges: losing the tax benefit, hidden costs, and losing control of investment decisions. The purpose of a 351 exchange is to defer paying taxes on appreciated stocks by not selling them.
Backdoor IRAs, carried interest, and life insurance are just some of the loopholes you can use to reduce your tax bills. It's important to plan correctly and use the right loopholes, credits, and deductions for your unique situation.
Section 351(a) provides that no gain or loss shall be recognized if property is transferred to a corporation by one or more persons solely in exchange for stock in such corporation and immediately after the exchange such person or persons are in control (as defined in § 368(c)) of the corporation.
Key Challenges in a 351 Exchange
Diversification Requirements: To qualify as a tax-free exchange under Section 351(a), the portfolio must be diversified. No single holding can exceed 25% of its value, and the top five holdings combined cannot exceed 50%.
Sole proprietors typically pay more in taxes. As a sole proprietor, you pay 15.3% self-employment tax on all your profits. With an S Corp, you only pay payroll taxes on your salary portion — the rest comes as distributions that aren't subject to self-employment tax.
The seller must have owned the home and used it as their principal residence for two out of the last five years (up to the date of closing). The two years don't have to be consecutive to qualify. The seller must not have sold a home in the last two years and claimed the capital gains tax exclusion.
Property tax deferral can be a great idea for seniors or those on fixed incomes needing cash flow to stay in their homes, freeing up equity, but it's not for everyone; you must repay the deferred amount plus accruing interest (which can be high) when the home is sold or ownership changes, and it adds a lien, potentially impacting heirs or credit, so weighing cash flow relief against future debt is key.
Any tangible asset constitutes property for purposes of the Section 351 transfer rules. Inventory, machinery, land, buildings, or equipment all qualify. However, the transferor must have a transferable interest in the tangible asset that is transferred in the exchange.
The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.
Benefits of a 1031 Exchange
Defer Capital Gains Tax: A 1031 exchange allows you to defer capital gains taxes, which can be substantial. This deferral can free up more capital for reinvestment, enabling you to acquire larger or more lucrative properties.
The IRS requires that those participating in an exchange fund hold their investment in the fund for 7 years. If you don't stay invested for the full 7 years, you'll likely be subject to taxes, penalties, and will receive your shares back at their original value or at the funds current value if lesser.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
You may be exempt from paying the tax if you are a:
If you sell your house and don't buy another, you'll have cash proceeds (after paying off the mortgage and selling costs) and need to decide on new housing, often renting or moving in with family; financially, you might benefit from the IRS capital gains exclusion (up to $250k/$500k profit if you've lived there two of the last five years), but you'll pay tax on gains beyond that, while also managing the new costs of renting or storage.
It allowed sellers to claim CGT exemption for the final 36 months of ownership, even if they had moved out. However, this was reduced to 18 months in 2014 and further to 9 months in 2020, which remains the rule today. This general law is in place as it prevents short-term transaction benefits concerning taxation.
This is known as the main rate of corporation tax. Those making less than £50,000 will pay a reduced rate of 19%. For companies with profits between £50,000 and £250,000, the main 25% rate still applies, but there's a 'sliding scale' of tax relief called Marginal relief.
The most tax-efficient way for many active LLC owners is to elect S-corporation status, paying yourself a "reasonable" W-2 salary subject to payroll taxes, with remaining profits taken as distributions (dividends) not subject to self-employment tax, saving ~15% on the distribution portion. For single-member LLCs or those with lower profits, owner's draws (flexible withdrawals) are simpler but all profits are subject to self-employment tax, while a salary-only approach (default LLC/sole prop) also taxes all net income at full self-employment rates. Always consult a tax professional, as the best method depends on your specific income and business structure.
The "2% rule" for S Corporations treats shareholders owning more than 2% of the company's stock (or voting power) differently for fringe benefits, classifying them like partners in a partnership, not regular employees; this means benefits like health insurance premiums paid by the S Corp must be included as taxable wages on their W-2, rather than being tax-free, though the shareholder can often deduct these premiums as an "above-the-line" deduction. This rule prevents them from participating in tax-advantaged Section 125 cafeteria plans, making benefits like Health FSAs unavailable on a pre-tax basis.
