NUA Strategy for Telecom Employees (AT&T, Verizon, T-Mobile)

Long-tenured employees at AT&T, Verizon, and their predecessor companies — Pacific Bell, Nevada Bell, SNET, Pacific Telesis, Ameritech, GTE, BellSouth — are among the strongest NUA candidates in the country. A 28-year career that started at Pacific Bell in 1994 and followed the SBC acquisition chain to today's AT&T can produce employer stock with a plan cost basis of $8–$12 per share at a current price of $17–$20 — a 1.5:1 to 2:1 ratio on the AT&T stock alone, but more importantly, the plan participant may also hold predecessor-company stock lots contributed before each merger exchange, with basis as low as $4–$8 per share from the early 1990s that translates to a 15:1 to 25:1 effective ratio on those specific lots. Three complications routinely cause planning mistakes: (1) merger-era basis chains that recordkeepers sometimes fail to preserve, (2) the 2022 AT&T/WarnerMedia spin-off that left employees holding both AT&T (T) stock and Warner Bros. Discovery (WBD) shares — only one of which qualifies for NUA, and (3) voluntary separation packages (VSPs) that compress the planning timeline to weeks rather than months. Getting any of these wrong can cost $50,000–$150,000 in unnecessary lifetime taxes.

Why telecom employees are strong NUA candidates

Several structural features of careers at AT&T, Verizon, and the legacy Bell companies make long-service employees particularly well-positioned for NUA elections:¹

• Long careers with continuous employer stock contributions. The Regional Bell Operating Companies (RBOCs) — Pacific Bell, Nevada Bell, SNET, Ameritech, BellSouth, Southwestern Bell — offered 401(k) plans with employer matching in company stock going back to the early 1980s. A 30-year employee who started receiving matching contributions in 1992 may hold stock lots with basis reflecting prices of $10–$20 per share that have been exchanged through multiple mergers into today's AT&T or Verizon shares.
• DB pension income reduces distribution-year bracket pressure. CWA (Communications Workers of America) and IBEW (International Brotherhood of Electrical Workers) represented employees at both AT&T and Verizon historically received defined benefit pensions. A long-service union employee may retire with $40,000–$60,000/year in pension income. Because the pension fills the lower ordinary income brackets first, careful timing of the NUA cost basis distribution can keep the basis hit in the 12%–22% range — particularly in the first year of retirement before Social Security begins.
• Voluntary separation packages create urgency but also planning opportunities. AT&T has repeatedly offered voluntary separation packages (VSPs) to its workforce — major rounds in 2017, 2019, 2020, and 2022. A VSP typically pays a lump-sum severance, extends benefits, and terminates employment — which is a qualifying event (separation from service) for NUA purposes. The complication: VSP windows are short (4–8 weeks to decide), leaving little time to run the NUA analysis.
• Many employees retired in states with no income tax. AT&T is headquartered in Dallas, TX; Verizon in Basking Ridge, NJ. Operations employees across the South, Southwest, Mountain West, and Pacific Northwest often retire to Texas, Florida, Nevada, or their home states. Employees who retire to a no-income-tax state capture both the federal rate spread (OI vs. LTCG) and zero state tax on the NUA appreciation — a combination worth $40,000–$100,000 for large positions.

The major telecom 401(k) plan landscape

The telecom industry has consolidated dramatically since 2000, and 401(k) plan recordkeepers have changed along with corporate mergers. This table reflects general plan characteristics as of 2026, but recordkeepers change; verify your current plan with the Summary Plan Description or HR benefits portal before making any distribution decisions.

Plan recordkeepers and benefit structures change with corporate activity. Verify your current plan details with the official Summary Plan Description (SPD) from your HR benefits portal. Recordkeeper phone numbers and portals should be confirmed via your most recent plan statement.

Merger-era basis chains: the most important variable for legacy telecom employees

The telecom industry went through the most complex wave of mergers in American corporate history between 1997 and 2006. Employees who were at any of the seven original Baby Bells or at GTE before these mergers may have employer stock contributions that trace back to pre-merger entities — with cost basis far lower than current market value.²

The AT&T/SBC merger chain

The modern AT&T is not the original AT&T. It is built from a series of acquisitions by Southwestern Bell (SBC) that eventually took the AT&T name:

• SBC acquired Pacific Telesis (Pacific Bell/Nevada Bell) in April 1997. Pacific Telesis shareholders received SBC shares at a fixed exchange ratio. Employees who had accumulated Pacific Bell or Pacific Telesis stock contributions since the 1980s converted those lots into SBC shares. Pacific Telesis stock in the late 1980s–early 1990s traded at $7–$12 per share. The basis on those early lots converted into SBC shares at the merger exchange ratio — and then again when SBC became AT&T in 2005.
• SBC acquired Ameritech (Illinois Bell, Ohio Bell, Indiana Bell, Michigan Bell, Wisconsin Bell) in October 1999. Long-service Ameritech employees who held employer stock since the early 1990s brought similar low-basis lots into the SBC/AT&T chain.
• SBC acquired AT&T Corp (long-distance/enterprise) in November 2005 and renamed itself AT&T. Legacy SBC employees' stock became AT&T (T) shares. The AT&T brand was reused but the corporate lineage runs through SBC, not the original AT&T Corp.
• AT&T acquired BellSouth (and its 40% stake in Cingular Wireless, making AT&T sole owner of AT&T Mobility) in December 2006. BellSouth employees who held BellSouth stock since the early 1990s may carry basis from that era into their current AT&T share lots.

What this means in practice: A 32-year AT&T legacy employee who started at Pacific Bell in 1992 may hold multiple cost basis lots in the AT&T Thrift Incentive Plan: early lots reflecting Pacific Telesis prices of $8–$12 per share (converted to SBC and then to AT&T at merger exchange ratios), mid-tenure lots from SBC-era contributions, and more recent AT&T-era contributions. The weighted average basis across all lots may be $8–$15 per AT&T share, versus a current T price of $17–$22. The ratio on the early Pacific Bell lots, however, may be far higher — often 15:1 to 25:1 when measured in terms of the economic return from the original stock price.

The Verizon merger chain

• Bell Atlantic merged with GTE to form Verizon Communications in June 2000. Bell Atlantic shareholders (including NYNEX and New England Telephone legacy employees, since Bell Atlantic had acquired NYNEX in 1997) and GTE shareholders (which included former Continental Telephone, Contel, and various independent telcos) received Verizon shares. GTE traded at $40–$65 in the late 1990s; Verizon has had a different share-price trajectory after integrating the two companies and taking on the wireless buildout debt.
• Verizon acquired MCI (the successor to WorldCom, which had itself acquired MCI Communications in 1998) in January 2006. Former MCI employees who held MCI stock in their plans had their employer stock effectively wiped out in WorldCom's 2002 bankruptcy and did not receive NUA-eligible stock. This is an important distinction: employees who joined Verizon through the MCI acquisition generally do not have pre-bankruptcy stock basis.
• Verizon acquired Vodafone's 45% stake in Verizon Wireless in February 2014. This was a cash deal — it did not affect plan participants' employer stock basis.

The key GTE insight: Long-service GTE employees who accumulated employer stock contributions from the 1980s through 1999 may have Verizon shares carrying GTE-era basis. GTE stock in the mid-1980s traded at $15–$25 per share; Verizon today trades at $40–$45. At first glance that appears to be a modest 2:1 ratio. But GTE shares split and the exchange ratio into Verizon shares creates a different per-share basis calculation — and employees who accumulated GTE shares continuously through the 1980s at prices well below $15 may have much lower lot-specific basis. A complete lot-level basis analysis is required before drawing conclusions.

The AT&T spin-off trap: T stock vs. WBD shares in your plan

In April 2022, AT&T completed the spin-off of WarnerMedia, merging it with Discovery Inc. to create Warner Bros. Discovery (WBD). AT&T shareholders — including AT&T Thrift Incentive Plan participants who held AT&T (T) stock — received 0.241917 shares of WBD for each AT&T share they held.³

This created a specific planning trap that affects NUA analysis for AT&T employees who were in the plan as of April 8, 2022:

• WBD shares received inside the plan are NOT employer stock for NUA purposes. The NUA election under IRC § 402(e)(4) applies only to securities of the employer — meaning AT&T (T) stock. Warner Bros. Discovery is a different company's stock. WBD shares held inside the AT&T Thrift Incentive Plan cannot be distributed in-kind and receive NUA treatment. They must be liquidated (or rolled to an IRA in cash) as part of the lump-sum distribution mechanics.
• AT&T (T) stock retained after the spin-off still qualifies. The AT&T shares that remain in the plan after the spin-off are still employer securities of AT&T Inc. The NUA election still applies to those shares. The distribution simply requires separating the AT&T employer stock (in-kind, NUA treatment) from the WBD shares (liquidated or rolled).
• The basis in AT&T stock changed after the spin-off. When a company spins off a subsidiary, the IRS requires shareholders to allocate their original cost basis between the retained shares and the distributed shares using a ratio based on the relative FMVs on the date of distribution. Participants who held AT&T shares before April 2022 should have received basis allocation information from their plan recordkeeper or a Form 1099-DIV (or plan statement). If this allocation wasn't properly documented, the basis figures in the plan may be incorrect — potentially understating the NUA by showing the pre-spin basis on AT&T shares without the proper basis reduction.

Voluntary separation packages (VSPs) as qualifying events

AT&T has offered at least five major VSP programs since 2017. Verizon conducted large workforce reduction programs in 2020. T-Mobile reduced its combined workforce significantly after the Sprint merger closed in 2020. For any employee who accepted a VSP, the termination of employment constitutes a "separation from service" — one of the four qualifying events under IRC § 402(e)(4) that enables the NUA election.¹

VSPs create a specific timing challenge for NUA planning:

• Decision windows are short. AT&T VSP election windows have typically been 4–8 weeks. During this window, employees must simultaneously decide whether to accept the package AND whether to elect NUA — because the NUA election requires the entire account balance to be distributed as a lump sum in a single tax year, and the triggering event (last day of employment) is the same event that starts the rollover clock.
• The 60-day indirect rollover deadline runs from distribution, not from separation date. If you receive any portion of the plan in a check (rather than direct rollover), you have 60 days to complete the rollover or it becomes ordinary income. This creates a forced timeline that can conflict with NUA execution: you need to arrange the in-kind stock transfer to a taxable brokerage account before the rollover deadline.
• Severance pay itself is not a qualifying event and doesn't help NUA. The VSP lump-sum severance payment is ordinary income, not a plan distribution. Only the 401(k) balance triggers NUA mechanics. The severance payment adds to your distribution-year ordinary income, which means it can push the cost basis distribution into a higher bracket. Model the interaction of severance + cost basis OI before deciding.
• Rule of 55 applies if you're age 55 or older in the separation year. If the VSP terminates your employment in a year when you're at least 55, the 10% early withdrawal penalty does not apply to the plan distributions in that year — including the cost basis distribution under NUA. This makes VSPs particularly favorable for late-career employees approaching 55 or already past that age. See NUA after layoff or early retirement for the full Rule of 55 analysis.

CWA/IBEW pension income stacking

Long-service union employees at AT&T and Verizon who are represented by CWA or IBEW may receive meaningful defined benefit pension income in retirement. This creates a two-sided planning consideration for NUA timing.⁴

The bracket floor issue

A $44,000/year pension fills the lower ordinary income brackets before the NUA cost basis distribution lands. For a married couple filing jointly with combined pension income of $60,000–$80,000, the cost basis distribution typically hits in the 12% to 22% range — a significant difference from the 22%–32% bracket it would land in for an employee with no pension who relies on IRA withdrawals for income. This is actually favorable: because the pension income bracket is already "filled" at a known level, the NUA cost basis tax rate is predictable and can be modeled precisely before committing to the election.

The bracket headroom for LTCG

The other side of the pension coin: because pension income covers basic living expenses, a retired telecom employee may not need to sell NUA stock to fund retirement in the early years. The NUA shares sit in the taxable account generating no ordinary income until sold. If the couple's taxable income from pension alone (after standard deduction) stays below the 0% LTCG threshold ($98,900 MFJ for 2026), the NUA stock can be harvested at 0% federal LTCG for years before Social Security adds to the income picture. A $40,000 pension covers expenses; the couple can sell $58,900 of NUA appreciation per year completely tax-free at the federal level before the 15% LTCG bracket kicks in.

IRMAA consideration

The cost basis distribution (ordinary income) in the NUA election year adds to MAGI for that year's IRMAA calculation — which then affects Medicare Part B and D premiums two years later. For most telecom employees taking the NUA election in their early 60s (before Medicare eligibility), the IRMAA lookback doesn't create a direct problem: the distribution-year MAGI spike appears in the IRMAA calculation at age 65 (two years after distribution), but the SSA-44 income reduction request can address a retirement-related income drop. Model this if your combined pension + VSP severance + cost basis OI is likely to push above $212,000 MFJ in the distribution year — that's the approximate 2026 threshold for the first IRMAA tier. See NUA and IRMAA for the full mechanics.

Former Sprint employees: T-Mobile shares after the April 2020 merger

When T-Mobile and Sprint completed their merger on April 1, 2020, Sprint's 401(k) plan was eventually merged into T-Mobile's plan. Sprint participants who held Sprint (S) stock received T-Mobile (TMUS) shares at the exchange ratio of approximately 0.10256 T-Mobile shares per Sprint share.⁵

The NUA implications for former Sprint employees:

• T-Mobile shares received in the plan merger are T-Mobile employer stock for NUA purposes. Once Sprint's plan merged into T-Mobile's plan and participants became T-Mobile employees (or separated from service from T-Mobile), the TMUS shares in the plan qualify as employer securities of T-Mobile for NUA purposes.
• The cost basis in TMUS shares reflects the Sprint-era acquisition cost, converted at the exchange ratio. If a Sprint participant had 1,000 Sprint shares with a plan cost basis of $5.00 per share ($5,000 total), and received 102.56 T-Mobile shares at the exchange, the T-Mobile shares have a basis of $5,000 / 102.56 = approximately $48.75 per share. With T-Mobile currently trading above $200 per share, that implies a ratio of approximately 4:1 — meaningful, but not as dramatic as the AT&T or Verizon merger chains because Sprint's merger was more recent (2020) and the base prices were higher.
• Long-tenure Sprint employees may have lower Sprint-era basis. Employees who accumulated Sprint shares in the early 2000s — when Sprint traded at $3–$8 per share during the wireless build-out era — have higher effective ratios. A Sprint share acquired at $4.00 becomes a T-Mobile share with basis of approximately $39/share, implying a 5:1 ratio at $200 TMUS. This is below the 10:1 threshold where NUA savings typically become very large, but it still produces a meaningful tax advantage for sizable positions and should be modeled explicitly.
• The qualifying event for former Sprint employees at T-Mobile is typically separation from service from T-Mobile. T-Mobile reduced its workforce significantly after the Sprint merger (eliminating duplicate roles), so many former Sprint employees either accepted separation packages or were laid off. That separation constitutes the qualifying event. Former Sprint employees who are still employed at T-Mobile can use the age-59½ qualifying event when they reach it.

Worked example: 32-year AT&T legacy employee

Patricia, age 63, is retiring under AT&T's 2024 voluntary separation program after 32 years — 3 years at Pacific Bell, 6 at SBC, and 23 at AT&T following the 2005 name change. Her AT&T Thrift Incentive Plan contains:

• $1,100,000 of AT&T (T) stock — employer match and voluntary contributions across 32 years. Plan cost basis: $44,000. This is a 25:1 ratio, reflecting Pacific Bell-era lots contributed at $8–$12/share (Pacific Telesis prices in 1992–1997) that have been exchange-ratio converted through each merger.
• WBD shares received in the April 2022 spin-off — liquidated and included in the non-stock balance
• $400,000 in diversified mutual funds → rolled to a traditional IRA
• Total plan value at distribution: $1,500,000

Patricia's income profile: CWA pension $58,000/year. Her husband's pension from a prior manufacturing job: $22,000/year. Texas resident, MFJ, no state income tax. Plans to claim Social Security at 67 ($36,000/year estimated). VSP severance: $80,000, paid by AT&T as regular W-2 compensation in the separation year.

Distribution year income analysis

Note: Patricia's distribution year includes VSP severance ($80K), which is ordinary income but is not a plan distribution. It does not affect the NUA election mechanics, but it does raise her total OI.

The incremental OI tax attributable to the cost basis distribution: $29,700 − $21,000 = ~$8,700. The marginal federal rate on the $44,000 basis is approximately 22% (the bracket where the incremental income lands, given VSP severance already pushed taxable income above $96,950 into the 22% bracket).

When NUA wins for telecom employees

• Pacific Bell / GTE / Ameritech / BellSouth-era basis from the early 1990s. These are the most favorable cases. Employees who accumulated employer stock contributions before the mergers converted those shares often have effective ratios of 15:1 to 25:1. At those ratios, the federal tax spread (22%–37% OI vs. 15%–20% LTCG) is large enough to save $80,000–$200,000 over the employee's lifetime, even in high-income VSP years.
• Texas, Florida, or Nevada retirement destination. AT&T's Texas headquarters and Verizon's major operations in many no-income-tax states mean that a significant share of the telecom workforce retires in states that fully preserve the federal LTCG benefit. California and New York residents face a meaningful state-level headwind — see below.
• DB pension covers basic expenses without IRA draws. Employees with CWA/IBEW pensions of $40,000–$65,000/year may not need to draw from the IRA for several years. During the window before Social Security, they can sell NUA stock in the 15% or even 0% LTCG bracket while the IRA continues compounding. This extended harvest window amplifies the NUA benefit.
• Estate planning angle for large positions. A $1M+ AT&T or Verizon stock position distributed via NUA offers heirs a step-up in basis on the post-distribution appreciation. Under OBBBA's permanent $15M estate exemption, few telecom retirees will owe estate tax — meaning the step-up is essentially free, and holding NUA stock until death converts the appreciation layer into a complete tax escape for the family.⁶

When NUA doesn't help telecom employees

• Low appreciation ratio despite long tenure. AT&T's stock has significantly underperformed the broader market for over a decade. An employee who accumulated AT&T stock primarily in the 2015–2023 era (post-DirecTV acquisition) may hold shares with a cost basis from $30–$38/share — close to or above the current price of $17–$22. At a ratio below 2:1, the NUA election rarely generates enough tax savings to justify the complexity. Run the calculator before assuming long tenure means a favorable ratio.
• California or New York residency. California taxes LTCG as ordinary income (9.3%–13.3%). New York similarly taxes capital gains at ordinary income rates (up to 10.9% state + 3.876% NYC tax for NYC residents). For a California-based AT&T or Verizon employee, the federal LTCG spread still applies, but the state-level advantage disappears entirely — and the cost-benefit calculation weakens substantially for lower-ratio positions. See NUA and State Taxes.
• VSP severance income pushes the basis OI into the 35%–37% bracket. For executives or high-earning managers with large VSP severance, NQDC payouts, and a substantial cost basis, the distribution-year ordinary income can reach the 35%–37% federal range. At those rates, the basis OI tax cost can exceed the savings from converting appreciation to LTCG — at least for the distribution year. In this situation, consider whether the in-service 59½ qualifying event (if eligible) in a lower-income year would produce better NUA economics.
• The plan requires stock liquidation before distribution. Some plans — especially at smaller telecom carriers or those that have changed recordkeepers multiple times — may not accommodate in-kind employer stock distributions. If the plan can only distribute cash (liquidated stock), NUA is impossible regardless of the appreciation ratio. Confirm in writing from the plan administrator before running the analysis.

Questions to ask your plan administrator

1. Does my plan hold AT&T (or Verizon / T-Mobile) employer stock as a distinct fund, and is in-kind distribution of actual shares — not liquidated proceeds — available at retirement or separation?
2. What is my lot-level cost basis for all employer stock, including lots contributed before any corporate merger (Pacific Bell, SBC, Ameritech, GTE, BellSouth, Sprint, etc.)? Are those predecessor lots tracked separately with their original acquisition dates?
3. Following the AT&T WarnerMedia spin-off (April 2022), were the Warner Bros. Discovery (WBD) shares separately accounted for in my plan record? What is the post-spin cost basis allocated to my remaining AT&T (T) stock lots?
4. Is a lump-sum distribution — the entire vested account balance distributed in one tax year — available under the plan document, and are there any installment-distribution defaults that I would need to override in writing?
5. What is the December 31 deadline for completing the in-kind stock transfer, and how far in advance do I need to initiate the request to ensure it clears by year-end?
6. After completing the NUA distribution, will the plan issue a 1099-R with the NUA amount in Box 6?
7. If I accepted a voluntary separation package, does my separation date constitute a qualifying event under the plan rules (i.e., is the plan treating it as separation from service for distribution eligibility purposes)?
