By Trading Options Inside an IRA: How It Works
Trading options inside an IRA rules out Reg T margin, so every short is fully collateralized. What limited margin does, and the assignment trap it creates.
Trading options inside an IRA runs on one mechanism that almost no broker page states plainly: a retirement account cannot pledge its assets or borrow against them. Regulation T margin, the Federal Reserve rule that lets a brokerage lend an ordinary account roughly half the price of a stock purchase, is unavailable here. Every short option has to be collateralized in full, in cash or in the shares themselves, and that single constraint generates the entire list of strategies a broker will approve.
Why an IRA cannot use Reg T margin
An IRA is a tax exempt trust with one beneficiary. Section 4975 of the tax code treats a loan between the account and its owner, and any pledge of account assets as security for a loan, as a prohibited transaction. A margin agreement is exactly that pledge: the securities in the account stand as collateral for the broker's credit line. Signing one puts the account's tax status at risk, so no US broker offers it on a retirement account.
Four mechanics follow, and they are identical at every firm:
- No debit balance, ever. Settled cash is the ceiling on any purchase.
- No short stock position. Borrowing shares requires the same agreement the account cannot sign.
- Every short option is collateralized the day it is opened: cash equal to the strike for a short put, the shares themselves for a short call.
- No maintenance call in the familiar sense. What replaces a call for more money is a forced close.
Trading options inside an IRA: what full collateral costs
A cash secured put parks the whole strike price in cash, 100 shares' worth, untouched until the contract is closed or expires. A covered call parks the shares. Both are fully funded positions, and the funding is the number worth looking at first. The choice between the two is laid out in covered call versus cash secured put.

GROUP BY underlying_symbol
ORDER BY cost_of_100_shares_k DESCThe panel prices near the money puts, 15 to 60 days out, across 6 household names. At the top of the table, SPY asks $76.1k in cash to secure a single put, against $77.1k to own the 100 shares a covered call needs. At the bottom, T takes $2.4k. A taxable margin account would post a fraction of those figures. In a retirement account the fraction is one.
The collateral does not work while it waits
Cash held against a short put cannot be pledged, reused, or applied to a second position. It stays committed for the life of the contract, and the premium is the whole of what the account collects for that commitment. The panel below prices premium as a percentage of the cash locked behind it.
Puts in the 1-14 days bucket priced at 0.67% of the cash they tie up on SPY and 1.83% on NVDA. Out at 121-365 days, the SPY figure was 4.08% of identical collateral, for a commitment lasting the full term. Same cash, different premium: the gap between the two series is implied volatility, the movement each name has priced into its contracts.
What limited margin in an IRA actually does
Some brokers offer retirement accounts a feature called limited margin, or IRA margin. The name misleads. It extends no credit whatsoever. What it does is let the account trade with unsettled proceeds.
Under the T+1 settlement standard adopted in May 2024, cash from a stock sale is available one business day later, and option trades settle on the same next day basis. A plain cash account may buy with unsettled proceeds, but selling that new position before the original sale settles books a good faith violation, and three of them in a rolling 12 months commonly brings a 90 day restriction to settled cash only. Limited margin removes that timing trap. The broker fronts nothing. It stops policing the settlement clock inside the account.
What limited margin still does not do:
- It does not allow a debit balance or an overnight loan.
- It does not allow short stock.
- It does not allow an uncovered short call.
- It does not reduce the collateral behind any short position by a single dollar.
Why spreads and naked calls get gated
An uncovered short call is unavailable in every retirement account. Delivery on assignment demands shares the account does not own, and the only way to produce them is a short stock position, which an IRA cannot hold. No broker policy is needed here; the account structure forbids the outcome. What a taxable account posts for the same trade is worked through in margin for selling naked options.
Vertical spreads sit in a grayer place. Their loss is capped, so firms that permit them hold the full width of the spread in cash, 100 dollars per point per contract, for the life of the trade. The gate is what happens between the legs. If the short leg is assigned, the account holds or owes stock for a day or more while the long leg is still an option, and financing that interim position is precisely what a retirement account has no credit for. Firms that allow IRA spreads reserve the right to close them without asking, and many act automatically in the last hour of an expiration session. Approval tiers differ by firm and get rewritten every few years, so read any level number as a snapshot of its publication date.
The assignment trap that no broker page states
In a taxable margin account, an assignment that leaves the account short of cash produces a margin call, and a wire transfer cures it by the deadline. In an IRA the same wire is a contribution. Contributions are capped by statute each year, at a few thousand dollars, and the cap does not bend for a trading emergency. Money cannot be added on demand.
The cure is mechanical instead. The position is closed, or shares are sold, at whatever the market offers that morning. The account owner is informed, not consulted. Assignment risk is not random either. It tracks moneyness, and it hardens into expiration.

AND underlying_symbol IN ('AAPL', 'MSFT', 'NVDA', 'SPY', 'KO', 'T')
GROUP BY strike_vs_spot
ORDER BY min(moneyness)Across calls with a week or less left, the 4%+ OTM bucket carried an average delta of 0.012. The 4%+ ITM bucket carried 0.958. Delta measures the option's price sensitivity to a one dollar move in the underlying, and near expiration it doubles as a rough read on the chance a contract finishes in the money. A short call at the right hand end of that curve is, for planning purposes, a sale of the shares already agreed.
Early assignment before an ex dividend date
American style equity options may be exercised on any business day before expiration, and the holder of an in the money call has one recurring occasion to do it early: the dividend. Exercising the day before the ex dividend date converts the call into shares in time to be on the record for the payment. The covered call writer on the other side delivers the shares and collects nothing. Early assignment on short options works through the arithmetic, and ex dividend dates and options covers the calendar mechanics.

GROUP BY ticker
ORDER BY dividend_per_contract_usd DESCCVX carries the largest payment in this group, $178 per 100 shares, with an ex dividend date of Aug 19, 6 days out. A short call whose remaining time value sits under that figure is a live candidate for exercise the day before. Inside an IRA the outcome is narrow and specific: the shares leave the account and the dividend never arrives.
Are option losses in an IRA deductible?
No. A loss realized inside an IRA never reaches a tax return. There is no capital loss to carry forward and no gain elsewhere to offset it against, and by the same logic no wash sale bookkeeping applies between two trades that both sit inside the account.
The exposure runs the other way. Selling a security at a loss in a taxable account and buying that security, or an option on it, inside an IRA within 30 days creates a wash sale, and Revenue Ruling 2008-5 holds the disallowed loss is gone for good. In a taxable account a wash sale defers the loss into the replacement position's basis. An IRA has no basis to adjust, so the deduction disappears rather than shifting forward. Wash sale treatment sits in Publication 550.
FAQ
Can you trade options in an IRA?
Yes, with broker approval. The available strategies are the fully collateralized ones: long calls and puts, covered calls, cash secured puts, and at many firms defined risk spreads. Uncovered short calls and short stock are unavailable in any retirement account.
What is limited margin in an IRA?
Permission to trade with unsettled proceeds, and nothing more. It extends no credit, allows no debit balance and no short stock, and does not shrink the collateral held against a short option.
What happens if an option in an IRA is assigned and the cash is not there?
The broker closes the position or sells shares to cover it. Depositing money is not a remedy: a deposit into an IRA counts as a contribution, capped annually by statute.
Are option losses in an IRA tax deductible?
No. Gains and losses inside a retirement account are not reported in the year they occur. A loss taken in a taxable account and replaced inside an IRA within 30 days is disallowed permanently under Revenue Ruling 2008-5.
Can you sell covered calls in an IRA?
Yes. The 100 shares per contract already held in the account are the collateral, which satisfies the full funding rule. Covered calls walks through the mechanics.
