I-Bond $10,000 Annual Limit Workarounds, How to Actually Stack $50K+ Per Year
| Instrument | Yield / rate | Source, as of |
|---|---|---|
| Series I bond composite rate (fixed 0.90%) | 4.26% | TreasuryDirect, bonds issued May 1, Oct 31, 2026 |
| 5-year TIPS real yield | 2.64% | U.S. Treasury real yield curve, 9/25/2026 |
| A-rated 5-year MYGA (top of market) | 5.50-6.05% | public carrier rate sheets, 10/14/2026 |
The I bond rate resets every May 1 and November 1; the fixed part (0.90%) is locked for the life of bonds bought through October 31, 2026. Since January 1, 2025, I bonds are sold electronically only, so the old $5,000 paper tax-refund route no longer exists.

The base limits, restated
| Purchase channel | Annual limit per SSN/EIN | Format |
|---|---|---|
| Personal TreasuryDirect account (electronic) | $10,000 | Electronic only |
| Tax refund (Form 8888 election) | Discontinued January 1, 2025 | Paper bonds no longer issued |
| Trust TreasuryDirect account | $10,000 per qualified trust | Electronic |
| Business / LLC / S-Corp entity account | $10,000 per entity EIN | Electronic |
| Gift purchase (held in giver's account, delivered later) | $10,000 per recipient per year delivered | Electronic |
A single individual can purchase: $10K personal = $10K/year baseline.
A married couple can purchase: $10K each personal = $20K/year baseline.
Everything else is stacking on top of this baseline.
Workaround 1: Revocable living trusts
The most common stacking method. A revocable living trust qualifies as a separate "entity" for TreasuryDirect purposes, with its own $10K annual limit.
How it works
- Establish a revocable living trust (most retirees already have one for estate planning purposes)
- The trust must have its own EIN OR can use the grantor's SSN with proper TreasuryDirect setup
- Open a TreasuryDirect "Entity Account" for the trust
- Fund and purchase $10K of I-Bonds per calendar year
The condition: The trust must be a real, properly executed legal document, not a workaround structure created solely for I-Bond stacking. Most estate-planning attorneys have a $1,500-$3,000 setup cost for a standard revocable trust. For a couple already maxing I-Bonds, the trust stack adds $10-20K/yr of additional I-Bond capacity, paying back the legal fees in 1-2 years.
Multi-trust stacking
A married couple with two separate revocable trusts (husband's trust + wife's trust) can each fund $10K to each trust = additional $20K/yr beyond personal limits. Plus the personal $10K each = $40K/yr total.
Some couples set up additional trusts (e.g., separate trusts for separate property in community-property states) to further multiply. The IRS has not flagged this as abusive, trusts are legitimate legal entities, but document the legal substance, don't just paper-create trusts for the I-Bond benefit alone.
Workaround 2: Business / LLC stacking
A single-member LLC or sole proprietorship with an EIN can open its own TreasuryDirect Entity Account and purchase $10K of I-Bonds per calendar year, independent of the owner's personal limit.
The legitimate setup
- Have a real business activity (consulting, rental property LLC, side business, freelance practice)
- The business must have its own EIN (IRS Form SS-4, free, online, 5 minutes)
- The business needs a business bank account separate from personal
- Open TreasuryDirect Entity Account using the EIN and the business name
- Purchase $10K of I-Bonds annually from the business's TreasuryDirect account
Tax treatment: Interest is reported on the business's books and flows through to the owner per the entity's tax classification (Schedule C for sole prop, K-1 for partnership, 1120-S for S-corp). For a single-member LLC defaulting to disregarded entity treatment, the interest just lands on Schedule C and gets taxed at owner's rate. No additional tax cost beyond personal ownership; just the additional $10K of I-Bond capacity.
Multiple LLCs
An investor with multiple real businesses (separate LLCs for different rental properties, for example) can stack $10K per LLC.
What does NOT work: Creating shell LLCs solely for I-Bond purchase. The IRS and TreasuryDirect can disregard structures that have no business substance. Each LLC needs real economic activity to avoid scrutiny.
Former workaround 3: $5,000 tax refund (Form 8888), discontinued
Older guides describe buying up to $5,000 of paper I-Bonds with a federal tax refund on Form 8888. That route is closed: per TreasuryDirect, as of January 1, 2025, I bonds are only available electronically. Over-withholding to create a refund for I-Bonds no longer works. Paper I-Bonds you already own still earn interest and can be converted to electronic bonds in TreasuryDirect.
Workaround 4: Gift Box mechanic (the most powerful)
The Gift Box is TreasuryDirect's least-known feature and the single most powerful I-Bond stacking tool.
The mechanic
- From your TreasuryDirect account, purchase an I-Bond as a "gift" for another person
- The gift bond is registered to the recipient's SSN but held in YOUR Gift Box: not delivered yet
- The bond starts earning interest immediately upon purchase, in the recipient's name
- Delivery to the recipient happens in a future year of your choosing
- The delivery counts against the recipient's $10K annual limit in the YEAR DELIVERED, not the year purchased
What this enables
You can stack $10K/year per spouse into each other's Gift Boxes, for years before delivery. Married couple example:
- Year 1: Husband buys $10K personal I-Bond + $10K gift to wife (in husband's Gift Box). Wife buys $10K personal + $10K gift to husband (in wife's Gift Box). Couple has purchased $40K of I-Bonds in year 1: with husband's $10K wife-gift and wife's $10K husband-gift earning interest in respective names but not yet delivered.
- Year 2: Same play. Total purchased: $80K cumulative. Gift Box bonds still undelivered.
- Year 3: Same. Total purchased: $120K cumulative. Each spouse has $30K of undelivered gift bonds in their Gift Box.
- Future delivery: At any time, each spouse can deliver the gift bonds to the other. The delivery counts against the recipient's $10K limit for that calendar year. Couple delivers $10K/year to each other to drain the gift box over time.
The Gift Box bonds earn interest at the prevailing I-Bond rates the entire time they sit in the box, the fixed-rate component is locked at the year of original purchase, not year of delivery.
This is the cleanest path to stacking $40K+ of I-Bonds per year per couple without legal entity setup. Many retirees use this when transitioning from high inflation periods (when locking in a high fixed-rate component is valuable) into uncertain rate periods.
Illustration: $80K of annual stacking
Hypothetical couple in their 60s, two adult children, one revocable trust each, one rental LLC each:
| Source | Amount/yr |
|---|---|
| Husband personal TreasuryDirect | $10,000 |
| Wife personal TreasuryDirect | $10,000 |
| Husband's revocable trust | $10,000 |
| Wife's revocable trust | $10,000 |
| Husband's rental LLC | $10,000 |
| Wife's rental LLC | $10,000 |
| Gift to Son 1 (held in Gift Box, future delivery) | $10,000 |
| Gift to Son 2 (held in Gift Box) | $10,000 |
| Total annual purchase | $80,000 |
The legal entity setup (trusts + LLCs) has to be real, in this illustration the couple has rental properties that justify the LLCs and standard estate-planning trusts. The Gift Box bonds to adult children remain in the parents' accounts until they choose to deliver (e.g., when the kids buy a house).
Over 5 years, this couple accumulates $400,000 of I-Bonds, each lot at the fixed rate in effect when it was bought, all state-tax-exempt, all federally tax-deferred until redemption.
When stacking doesn't make sense, the MYGA crossover
Stacking I-Bonds via trusts, LLCs, and gift box requires significant administrative effort. The crossover threshold where a MYGA simply wins on after-tax return for a retiree:
I-Bond composite rate = 4.26% (0.90% fixed + inflation component) for bonds issued May 1, October 31, 2026 (TreasuryDirect)
A-rated 5-year MYGA = about 5.50-6.05% guaranteed (public carrier rate sheets, October 14, 2026)
The MYGA pays roughly 155-175 bps more per year at today's rates. On $100K over 5 years, if the I-Bond rate stayed at 4.26% (it resets every six months), the MYGA would pay roughly $9,000-$10,000 more in nominal interest. After tax the gap narrows (I-Bond interest is state-tax-exempt; MYGA interest is fully deferred but eventually taxable), and the I-Bond pulls ahead if inflation rises enough to lift its variable component.
The MYGA is worse than I-Bonds for:
- Inflation protection (MYGA is fixed-rate; I-Bond floats with CPI)
- Liquidity (MYGA has surrender charges 7-10 years; I-Bond has 12-month lockup then 3-month penalty)
- FDIC-equivalent safety (MYGA is state guaranty fund, not federal)
Recommended hybrid for a retiree with $300K of conservative-bucket cash:
- $30K/year stacked I-Bonds (max personal + trust) for inflation insurance, held to maturity
- $200K MYGA ladder (3/5/7 year) for the bulk of the bucket, yield optimization
- $70K HYSA or VUSXX for true daily-liquidity reserve
This combination captures the I-Bond inflation hedge at the limit, the MYGA's superior yield at scale, and operational simplicity by not over-engineering trust/LLC stacking unless you already have those structures.

FAQ
Q: How many I-Bonds can a married couple legally buy in one year?
A: Baseline $20K ($10K each; the $5K paper tax-refund option ended January 1, 2025). With one revocable trust each, add $20K = $40K. With Gift Box mechanics holding spouse-to-spouse gifts, can add another $20K = $60K+ in purchases. With LLCs, additional $10K each. Practical maximum without exotic structures: $80-100K/year.
Q: Is the Gift Box workaround legal?
A: Yes, it's an official TreasuryDirect feature with published rules. The gift remains in the giver's account earning interest in the recipient's name, then is delivered (and counts against recipient's limit) in a future year. Treasury designed the feature; many financial planners use it routinely.
Q: Do I need a CPA to set up I-Bond stacking through a trust?
A: An attorney for the trust document, not a CPA. The trust must be a legitimate legal entity. Once set up, the trust's TreasuryDirect entity account is straightforward. A CPA helps with the tax reporting (trust interest may flow through to the grantor or beneficiaries depending on trust type).
Q: Can I gift I-Bonds to my children right now?
A: Yes, via Gift Box. Purchase in your account as a gift, registered to child's SSN. Holds in your Gift Box until you choose to deliver. If you deliver $10K/year, it counts against the child's annual limit; over-delivery in one year voids the excess.
Q: Does the IRS care about I-Bond stacking via entities?
A: The IRS has not challenged legitimate I-Bond stacking through real trusts and businesses. The concern would be sham entities with no business purpose. Document substance: real trust with proper assets, real business with real activity.
Q: How quickly can I redeem stacked I-Bonds in an emergency?
A: Same 12-month minimum hold applies to every I-Bond regardless of entity owner. After 12 months, redeem from any TreasuryDirect account where you're a signatory. 3-month interest penalty if redeemed within 5 years (waived after 5 years). For true emergency liquidity, keep a separate HYSA or VUSXX buffer.
Q: Can I buy more I-Bonds for my kids than the gift box trick allows?
A: You can open a TreasuryDirect account in their name (with SSN) and have them "own" up to $10K/yr in their own account, separate from any gift box deliveries from you. For minors, this requires a custodial account setup at TreasuryDirect, less common but possible.
Q: Is there a lifetime limit on I-Bonds?
A: No lifetime limit, only annual limits per entity. A couple stacking $50-80K/yr for 20 years can accumulate $1M-$1.6M of I-Bonds over a lifetime.
