Rule 144 Tacking: 2026 Practitioner Walkthrough

If you hold restricted securities and want to sell without registration, the question is almost always the same: does your holding period start from when you acquired the shares, or can you count time a prior holder already logged? That is the tacking question, and getting it wrong means either selling too early (a Securities Act violation) or waiting longer than you legally need to.

This walkthrough covers every permitted tacking scenario under Rule 144(d), the scenarios where tacking is flatly unavailable, and the practical traps that catch even experienced practitioners. For a broader overview of all Rule 144 resale conditions, see our Rule 144 Resale Conditions: 2026 Practitioner Walkthrough.

What Is Rule 144 Tacking and Where Does It Come From?

Tacking is the doctrine that allows a holder of restricted securities to aggregate successive holding periods to satisfy Rule 144's minimum holding period requirement. Instead of restarting the clock every time shares change hands in a qualifying transaction, the new holder inherits the prior holder's accumulated time.

The legal foundation is 17 CFR § 230.144(d), which sets the minimum holding periods:

• Six months for restricted securities of a reporting issuer (a company subject to Exchange Act Section 13 or 15(d) reporting for at least 90 days before the sale)
• One year for restricted securities of a non-reporting issuer

The SEC's investor guidance states it plainly: "The relevant holding period begins when the securities were bought and fully paid for. The holding period only applies to restricted securities."

Two points practitioners often miss:

1. Tacking applies only to the holding period under Rule 144(d). It does not carry over to the volume limitations, manner-of-sale requirements, or current public information conditions. Those conditions are assessed independently at the time of sale.
2. Control securities held by affiliates have no holding period requirement under Rule 144. The holding period clock is a restricted-securities concept only.

Key takeaway: The 2008 amendments (SEC Release No. 33-8869, effective February 15, 2008) cut the non-affiliate holding period for reporting-issuer shares from one year to six months. Many online resources still cite the old one-year rule for all issuers. That is wrong for reporting issuers. Always confirm whether the issuer is a reporting company before applying the six-month period.

The Full Payment Requirement: Where the Clock Actually Starts

The holding period does not begin until the securities are "bought and fully paid for." This is not a technicality; it is a hard rule with real traps.

Common situations where the clock has not yet started:

• Installment purchases. If you bought 1,000 restricted shares and paid for them in installments, the holding period runs separately for each tranche as each payment clears. The SEC's Compliance and Disclosure Interpretations (C&DIs) confirm this: an investor who paid off half a promissory note over six months has satisfied the holding period only for the shares corresponding to that half payment.
• Promissory notes as consideration. A note used to purchase restricted securities does not constitute full payment unless it is full-recourse and adequately secured, per SEC staff guidance. If the note does not meet that standard, the clock starts only as actual payments are made.
• Cashless exercises of warrants and options. Whether the holding period of the warrant or option tacks onto the underlying shares is a contested area. The SEC staff has not issued a blanket permission. The safer position: the holding period for shares received in a cashless exercise begins at exercise, not at the grant date of the warrant or option. Seek a no-action letter for any novel structure here.

When Tacking Is Permitted: The Complete Scenario Map

Bona Fide Gifts

This is the clearest case. When restricted securities are transferred as a bona fide gift, the donee may tack the donor's holding period. The SEC's guidance confirms this directly. It does not matter whether the donor was an affiliate; the donee inherits the accumulated time.

The catch: the transfer must be a genuine gift with no consideration. A transfer dressed up as a gift but with side payments or reciprocal arrangements will not qualify.

Conversions and Exchanges Within the Same Issuer

Rule 144(d)(3) explicitly permits tacking when:

• Securities are acquired from the issuer solely in exchange for other securities of the same issuer (e.g., a stock split, reclassification, or recapitalization)
• Securities are received as a stock dividend
• Securities are acquired upon conversion or exchange of other restricted securities of the same issuer, with no additional consideration paid

For PIPE investors holding convertible notes or preferred stock, this is the key provision. If you hold a convertible note in a reporting company and convert it to common shares without paying anything extra, your holding period for the common shares dates back to when you acquired and fully paid for the note.

The SEC's C&DIs confirm a related point: if a preferred stockholder tenders shares to the issuer and receives a new series of preferred plus cash, the stockholder may still tack the holding period for the old preferred onto the new series.

Key takeaway: No new consideration = tacking permitted on conversion. Any new cash or other consideration paid at conversion resets the clock for the incremental consideration paid.

Intra-Entity Distributions (Partnerships, Corporations, Trusts)

The SEC staff has confirmed tacking in several intra-entity scenarios:

• A closely-held corporation that distributes restricted securities pro rata and without consideration to its shareholders (even if those shareholders are limited partnerships, which then distribute to their partners) may tack. The holding period flows from the corporation through the partnerships to the individual partners.
• Pro rata redemptions of partnership interests in a closely-held investment partnership, where partners receive restricted securities in kind on liquidation, allow partners to tack the partnership's holding period.
• New investors in a closely-held investment partnership, and existing partners who receive redistributed assets when other partners withdraw, may also tack, provided the fundamental character of the partnership is not changed.

The critical limit: if an affiliate transfers restricted stock to a corporation it controls (say, an 84% owned subsidiary) and the corporation intends to sell the shares and remit proceeds back to the affiliate, tacking is not permitted. The SEC treats that transfer as a private sale that starts a new holding period. The structure cannot be used to launder an affiliate's holding period through a controlled entity.

Estate Transfers and Inheritance

Restricted securities transferred to an estate or distributed to beneficiaries from an estate carry the decedent's holding period. The beneficiary tacks the decedent's time. This is consistent with the gift-tacking principle and has been confirmed in SEC staff guidance.

Underwriter and Finder Shares

This scenario is more nuanced. When an underwriter or finder holds shares that are technically restricted (because the original sale was not made with a current prospectus or under the constructive Rule 144 safe harbor), a purchaser of those shares from the underwriter or finder may tack the underwriter's or finder's holding period, provided the underwriter or finder is not an affiliate of the issuer.

If the underwriter or finder transfers the shares to its own employees, those employees may also tack the firm's holding period for Rule 144(d) purposes. However, they must aggregate their sales with those of other employees and with the firm itself for volume limitation purposes for one year from the date of transfer.

Purchases from a Non-Affiliate

When you buy restricted securities from a non-affiliate, you may tack the seller's holding period. This is the standard secondary-market tacking case.

Tacking is not available when you purchase from an affiliate. A purchase from an affiliate starts a fresh one-year holding period (for non-reporting issuers) or six-month period (for reporting issuers). The Willkie Farr client memo on the 2008 amendments states this directly: "Tacking is not allowed, however, in the case of a purchase from an affiliate; such a purchase starts new one- and two-year holding periods."

When Tacking Is Not Available

Pledges deserve a closer look. If a pledgor (who is an affiliate) defaults and the pledgee forecloses, the pledgee acquires restricted securities and generally cannot tack the pledgor's period. However, if the pledgee never took beneficial ownership and the pledge was purely collateral, the pledgor retains the holding period. The SEC's C&DIs (Section 532.01) address this: a non-affiliate pledgee who forecloses on shares pledged by an affiliate may resell under Rule 144(b)(1) without regard to the holding period, but subject to the current public information requirement. The mechanics depend heavily on whether the pledgee is itself an affiliate.

Short sales are a trap. A holder of restricted securities who has not yet satisfied the holding period cannot effect a short sale of the same class and then cover with the restricted shares once the period is met. The initial short sale did not qualify under Rule 144, so the cover does not either.

Compensation shares (RSUs, options) have their own timing rule. The SEC's C&DIs (Section 532.06) confirm that for restricted securities issued under an individually negotiated employment agreement, the holding period begins when the securities vest, not at grant. This is different from shares issued under a formal employee benefit plan covered by Securities Act Release No. 6099, and it is different from tax holding period concepts.

The M&A Tacking Problem: The Economic Risk Test

This is where most practitioners get tripped up. In a stock-for-stock merger or acquisition, the intuition is that target shareholders who held their shares for years should be able to tack that time onto the acquirer's shares they receive at closing. That intuition is wrong.

As Cooley summarized from the SEC's 2007 FAQs: "The Rule 144 holding period for recipients of the acquiring corporation's stock will not begin until the closing because the recipients will not be at economic risk with respect to the acquiring corporation's stock until that time."

The economic risk test is the governing principle. A holder is at economic risk with respect to a security only when they have made a binding commitment to acquire it and are exposed to the market risk of that specific security. In a stock-for-stock deal:

• Before closing, target shareholders bear the risk of the target's shares, not the acquirer's.
• The exchange ratio may be fixed, but the acquirer's share price can move, and the deal can fall apart.
• Only at closing do the target shareholders actually hold acquirer shares and bear acquirer-specific market risk.

The SEC's C&DIs (Section 532.04) confirm this with a concrete example: in a stock-for-stock acquisition where closing is delayed until the acquired company's year-end revenues are determined (giving the acquirer an out if revenues miss a threshold), the holding period for the acquirer's shares does not begin until closing.

Practical implication: A target shareholder who held restricted target shares for five years receives acquirer shares at closing and must hold those acquirer shares for six months (reporting issuer) or one year (non-reporting issuer) before selling under Rule 144. The five years of target-share holding counts for nothing.

Re-domiciliations and holding company insertions follow the same logic. If a company re-incorporates or inserts a new holding company above itself in a reorganization, and shareholders receive new-issuer shares in exchange, the holding period for the new shares generally begins at the closing of the reorganization, not when the original shares were acquired. Practitioners should analyze whether the transaction constitutes a new acquisition for Rule 144 purposes and, if the answer is uncertain, seek a no-action letter.

The Anti-Evasion Principle

Rule 144's safe harbor is not available to any person whose transaction, though technically compliant with the rule, is part of a plan or scheme to evade registration. 17 CFR § 230.144, Preliminary Notes states this directly.

What does evasion look like in practice?

• Structuring a series of tacking-eligible transfers (gift to family member, then to trust, then to partnership) specifically to accelerate the holding period without genuine change in economic ownership.
• Selling restricted securities offshore under Regulation S and then arranging for the securities to return to U.S. markets shortly after. The SEC has warned that any arrangement to return restricted securities to U.S. markets may indicate an evasive scheme, which would invalidate any safe-harbor claim.
• Using a controlled entity to hold shares and sell them while the affiliate retains the economic benefit, as in the 84%-owned-corporation scenario above.

If the structure's primary purpose is to manufacture a tacking argument rather than to reflect a genuine change in ownership or economic position, the safe harbor falls away.

Bankruptcy Reorganizations: A Special Case

Securities received under Section 1145(a) of the Bankruptcy Code are not restricted securities. They are deemed received in a public offering under Section 1145(c), so the tacking and holding period analysis under Rule 144 does not apply.

However, if a company in bankruptcy issues shares to an unrelated party for a business acquisition under Section 4(2) of the Securities Act (not Section 1145), those shares are restricted securities subject to Rule 144's holding period. The distinction turns on which exemption the issuance relies on, not on the fact of bankruptcy.

Regulation S Interaction

Restricted securities can be resold in markets outside the United States under Rule 144 or Regulation S. But the SEC has been explicit: any arrangement to return those securities to U.S. markets may signal an evasive scheme. Tacking arguments built on offshore transfers followed by U.S. re-entry are high-risk and should be reviewed carefully before execution.

Step-by-Step: How to Determine Whether Tacking Applies

1. Confirm the securities are restricted. Check Rule 144(a)(3): were they acquired in a non-public offering from the issuer or an affiliate, under Reg D, Rule 144A, Reg S, or Rule 145(d)? Control securities held by affiliates have no holding period requirement.
2. Identify the applicable holding period. Is the issuer a reporting company (Exchange Act Section 13 or 15(d) filer for at least 90 days)? If yes, six months. If no, one year.
3. Map the chain of title. List every prior holder and how the securities passed between them. For each transfer, ask: was new consideration paid? Was the transferor an affiliate at the time?
4. Apply the tacking rules to each link in the chain.
   • Gift, pro rata distribution, conversion with no new consideration, estate transfer: tacking permitted.
   • Purchase from an affiliate: clock resets.
   • New consideration paid: clock resets for the incremental amount.
5. Check the full payment requirement. For each acquisition in the chain, confirm the securities were fully paid for at the time claimed. Installment payments and non-qualifying notes break the chain.
6. Apply the economic risk test for M&A shares. If the securities were received in a business combination, the holding period begins at closing, not at the acquisition date of the target shares.
7. Confirm no anti-evasion issue. Is the structure designed to reflect genuine economic ownership, or to manufacture a tacking argument?
8. Assess whether a no-action letter is needed. Novel structures, cashless exercises, re-domiciliations, and complex PIPE conversions are all candidates.

FAQ

What is the holding period for Rule 144 in 2026? Six months for restricted securities of a reporting issuer (one that has filed Exchange Act reports for at least 90 days before the sale). One year for restricted securities of a non-reporting issuer. These periods have applied since the 2008 amendments took effect on February 15, 2008.

Can I tack the holding period of shares I received as a gift? Yes. A donee may tack the donor's holding period for Rule 144(d) purposes. It does not matter whether the donor was an affiliate of the issuer.

Does converting a convertible note reset the holding period? No, provided no additional consideration is paid at conversion. Under Rule 144(d)(3), the holding period of the convertible instrument tacks onto the underlying shares received on conversion. If new cash or other consideration is paid at conversion, the clock resets for that incremental amount.

In a stock-for-stock merger, when does the holding period for the acquirer's shares start? At closing. Target shareholders are not at economic risk with respect to the acquirer's shares until the merger closes. The holding period in the target shares cannot be tacked onto the acquirer's shares, regardless of how long the target shares were held.

Does tacking apply to the volume limitations and other Rule 144 conditions? No. Tacking applies only to the holding period under Rule 144(d). Volume limitations, manner-of-sale requirements, and the current public information condition are assessed independently at the time of sale.

When does the holding period start for shares received under an employment agreement? For restricted securities issued under an individually negotiated employment agreement, the holding period begins when the securities vest and any conditions (such as continued employment) are satisfied. The grant date does not start the clock.

Can an LLC member or trust beneficiary tack the entity's holding period? Generally yes for pro rata distributions without consideration, as confirmed in the SEC's C&DIs for closely-held partnerships and corporations. The key conditions: the distribution must be pro rata, without consideration, and must not fundamentally change the character of the entity.
