Tennessee Taxes on RSUs and Stock Options: A Tech Employee's Guide

Tennessee has never taxed earned income. Unlike Nevada — which prohibits an income tax via its state constitution — Tennessee's zero-wage-tax status is statutory, but the political environment is so firmly against a state income tax that the legislature repealed its last income-related levy (the Hall income tax on dividends and interest) effective January 1, 2021, fully eliminating any state income-tax exposure for individual residents. A software engineer vesting $400,000 of RSUs in Nashville pays zero Tennessee state tax on that income — the same number that applies to wages, bonuses, ESPP income, and NSO exercise spreads.

The state's tech ecosystem has grown meaningfully. Oracle moved its corporate headquarters from Redwood City, California to Nashville in December 2021, relocating thousands of employees and establishing a major downtown campus. Asurion — the technology protection and support company with roughly 6,000 Nashville-area employees — is one of the largest private tech employers in the Southeast. HCA Healthcare, headquartered in Nashville, has invested heavily in digital health and technology infrastructure. AllianceBernstein relocated its headquarters from New York to Nashville in 2022. Amazon operates a significant regional distribution and logistics hub in the area. Together with a growing startup ecosystem and Vanderbilt University's research computing presence, Nashville has built genuine critical mass as a technology employment market.

The tax picture is almost entirely favorable for tech employees with equity compensation — with one notable exception. Tennessee's sales tax is 9.75% in Nashville/Davidson County (7% state plus 2.75% county), among the highest combined rates in the country. On large purchases — a car, home appliances, or construction materials for a home renovation — this is a meaningful cost that Californians and New Yorkers moving to Tennessee should factor into their planning. This guide covers how Tennessee taxes RSUs, ISOs, NSOs, and ESPP; what relocating from California means for your existing grants; and the planning strategies worth knowing for 2026.

Tennessee's tax structure for tech employees

RSUs in Tennessee: federal-only at vest

At vest: no state withholding

When RSUs vest, the fair market value at the vest date is ordinary income — taxed by the IRS at your marginal rate. Federal income tax is withheld at the 22% supplemental rate (which underwithholds for most tech employees above $190K total income, where higher brackets run to 32% and 37%). Social Security applies on the first $176,100 of combined wages and RSU income; Medicare at 1.45% on all compensation; Additional Medicare Tax at 0.9% on income above $200K single / $250K MFJ.

Tennessee adds nothing on top of this. No state income tax, no state supplemental withholding. Use the RSU after-tax calculator and enter $0 for state income tax — that is the correct number for Tennessee residents.

After vest: capital gains are federal-only — and Tennessee beats Washington

Your cost basis in the vested shares equals FMV at vest. If you hold the shares and they appreciate, selling after 12+ months qualifies the gain for federal long-term capital gains rates (0%, 15%, or 20% depending on income, plus 3.8% NIIT). Tennessee taxes none of this gain at the state level.

This places Tennessee ahead of Washington state for employees who hold and sell appreciated tech stock. Washington's Capital Gains Income Tax (CGIT) applies 7% on net LTCG above its annual threshold and 9.9% above $1M under ESSB 5813 (see the Washington equity tax guide). Tennessee's $0 state capital gains tax is a structural advantage for tech employees holding concentrated positions in employer stock, appreciated ESPP lots, or startup stock with embedded gain.

ISOs in Tennessee: federal AMT only

Exercise with only federal AMT exposure

Incentive Stock Options create an AMT preference item at exercise: the spread (FMV minus strike price) is not taxable for regular federal income tax purposes, but it is included in Alternative Minimum Tax income. The 2026 federal AMT exemption is $90,100 (single) and $140,200 (MFJ), with the phaseout starting at $500,000 (single) / $1,000,000 (MFJ) at a 50-cent reduction per dollar above the threshold — per IRS Rev. Proc. 2025-32 and modified by OBBBA.⁵

Tennessee imposes no state AMT on ISO exercises. This is a material advantage over California, which taxes ISO exercises at a state AMT rate of 7% on the entire spread regardless of the federal AMT outcome. On a $500K ISO spread, California's state AMT alone adds $35,000 in tax; Tennessee adds $0. Colorado levies a 3.47% state AMT; Minnesota a 6.75% state AMT. Tennessee has none of these. Use the ISO AMT calculator to estimate your federal AMT exposure and the maximum shares you can exercise without triggering AMT.

NSOs in Tennessee: ordinary income at exercise, federal-only

Non-Qualified Stock Options generate ordinary income at exercise equal to the spread (FMV minus strike price). That income is subject to federal income tax, Social Security (up to the $176,100 wage base), Medicare, and Additional Medicare Tax. In Tennessee, state tax on NSO exercise income is $0. This makes Tennessee a structurally clean state for startup founders or employees with large NSO portfolios — you pay federal tax on exercises and nothing at the state level.

ESPP in Tennessee: qualifying and disqualifying dispositions are both federal-only

Under a §423 ESPP, a disqualifying disposition (selling within 2 years of the offering start date or 1 year of the purchase date) recognizes the discount as ordinary income — taxed federally, $0 in Tennessee. A qualifying disposition (holding longer) splits the gain into a compensatory element (ordinary income) and appreciation (long-term capital gains) — both taxed federally, $0 in Tennessee. Use the ESPP after-tax calculator to model the qualifying vs. disqualifying disposition comparison at your income level and tech company's purchase discount.

California's long-arm sourcing after you move to Tennessee

Relocating to Tennessee eliminates California state income tax on income you earn after you establish Tennessee domicile. But it does not immediately eliminate California's claim on RSU grants and option grants already in progress when you moved.

The grant-to-vest workday allocation

California sources RSU income using a grant-to-vest workday ratio: California workdays during the vesting period ÷ total workdays during the vesting period. If you received a 4-year RSU grant, worked 3 years in California, then moved to Tennessee for the final year, California still taxes you on roughly 75% of the RSU income from that grant when it vests — even after your move. The remaining 25% (earned during the Tennessee year) is California-tax-free.

For Oracle employees who relocated from Redwood City to Nashville in late 2021 or 2022: grants received before your move continue to carry a California allocation until each grant's vesting schedule ends. A 4-year grant received in 2020 that vests through 2024 has roughly 25–50% of each vest allocated to California depending on exactly how many months you worked in California during that grant's vesting period. New grants received entirely after your Tennessee domicile is established have zero California component.⁶

What establishes Tennessee domicile

California's Franchise Tax Board applies a "closest connection" test and scrutinizes the full facts pattern. Contemporaneous documentation matters more than self-reporting after the fact. Key steps for a defensible Tennessee domicile claim:

• Obtain a Tennessee driver's license and surrender your California license
• Register to vote in Tennessee (and deregister in California)
• Move substantial personal property to Tennessee
• Register vehicles in Tennessee
• Update professional memberships, doctors, dentists, bank accounts, and subscriptions to a Tennessee address
• Maintain a contemporaneous log of workdays in each state — particularly for years with large vest events where the California allocation is material
• If you own a Tennessee home: keep property-related documentation (mortgage, insurance, utility bills) in Tennessee to evidence your primary residential connection

New York's long-arm rules also apply if you worked in New York

Tech employees moving to Tennessee from New York face a similar nonresident sourcing rule, plus New York's "convenience of employer" rule, which can treat remote workdays as New York workdays if you work remotely for a New York employer because it's convenient for you rather than required by the employer. See the remote work state tax guide for the full analysis.

Property taxes in Tennessee

Tennessee's property taxes are moderate by national standards. Tennessee assesses residential property at 25% of appraised (market) value — a low assessment ratio that means the effective tax rate on market value is significantly lower than the nominal rate per $100 of assessed value suggests. Davidson County's Urban Services District (covering most of incorporated Nashville) uses a combined rate of $2.814 per $100 of assessed value, translating to approximately 0.70% of market value.³

On a $1M Nashville home, that's roughly $7,000/year in property tax — well below comparable homes in Austin (~$14,000–$18,000/year), San Jose (~$10,000–$14,000/year), or New York (~$10,000–$20,000/year depending on the borough). Shelby County (Memphis) and Knox County (Knoxville) have different rates; Davidson County is the relevant benchmark for Nashville tech workers.

On the SALT deduction: the 2026 SALT cap is $40,400 (raised from $10K by OBBBA, with a phaseout above $500K MAGI). In Tennessee, your SALT deduction is almost entirely property taxes — there's no state income tax consuming the cap. In California, state income tax alone at 13.3% on $600K of income would be $79,800, far exceeding the $40,400 cap. This is a meaningful federal benefit for Tennessee homeowners vs. California homeowners at equivalent income levels.

The sales tax gotcha

Tennessee's 9.75% combined sales tax rate in Nashville (7% state + 2.75% Davidson County) is one of the highest in the country. For tech employees moving from California (7.25% minimum + 1–3% local = typically 8.25%–10.25% in the Bay Area), the sales tax may not feel dramatically different in everyday life. But on major purchases — a new car ($50,000 vehicle = $4,875 in sales tax), home furnishings, appliances, or significant discretionary spending — the rate is material.

Tennessee does not tax groceries at the full rate (food sold in grocery stores is taxed at 4% state rather than 7% state), and prescription drugs are exempt.⁴ But durable goods and most services are taxed at the full combined rate. This is the primary cost to factor in when modeling the full financial picture of a California-to-Tennessee move.

Estate planning in Tennessee: clean slate under OBBBA

Tennessee repealed its state estate tax effective January 1, 2016 — one of the earlier state-level repeals. There is no state inheritance tax or gift tax in Tennessee.² The OBBBA permanently set the federal estate exemption at $15M per person ($30M per couple, with inflation adjustment going forward). Tech employees with $5–10M in total wealth — achievable after a decade at Oracle, a major tech company, or a successful startup outcome — are typically below the federal threshold.

Senior ICs and executives in Nashville can hold appreciated stock, max out annual gifts ($19K per recipient in 2026), and use the full $15M exemption for larger wealth transfers without any state-level estate tax complication. For Oracle or HCA employees who relocated from California or New York, this can represent a significant simplification: California has no estate tax (the federal exemption applies), but high-wealth California residents face other complexities; New York has a $7.16M estate tax threshold with a "cliff" that can tax the entire estate. Tennessee has none of this.

Planning strategies for Tennessee tech employees

1. Maximize retirement accounts to capture the full federal deduction

With no state income tax, the value of 401(k) contributions is purely federal. Maxing a traditional 401(k) at $24,500 (2026) at a 37% marginal rate saves $9,065 in federal tax — you don't get additional state savings on top, but you don't lose any either. If your employer allows after-tax contributions with in-plan Roth conversion, Mega Backdoor Roth contributions (up to the $72,000 total §415(c) limit in 2026) compound tax-free for decades. Use the Mega Backdoor Roth calculator for your specific contribution space. For employees who were moved from California to Tennessee, note that both traditional and Roth 401(k) contributions also reduce California-sourced income during the allocation period — a secondary benefit in years when you're still filing as a California nonresident.

2. Use Tennessee's 0% LTCG as a hold-vs-sell signal for appreciated shares

In California, holding vested RSU shares post-vest provides no state-level benefit — California taxes LTCG as ordinary income at the same rate as ordinary income. In Tennessee, the state comparison is 0% either way, so the federal trade-off — 37% ordinary income now vs. 20% + 3.8% NIIT after 12 months — applies cleanly. Unlike Washington, you don't need to watch for the CGIT threshold. Holding for LTCG treatment is worth modeling when concentration risk is manageable. See the concentrated stock guide for the full framework on lot selection, 10b5-1 plans, and exchange funds.

3. Donate appreciated stock to eliminate federal LTCG entirely

Even without state capital gains tax, federal LTCG + NIIT on a large appreciated position is 23.8% — worth eliminating if you have charitable intent. Donating appreciated employer stock directly to a donor-advised fund (DAF) avoids realizing the gain. You get the charitable deduction at full FMV, pay no capital gains, and the DAF distributes to your chosen charities over time. The 2026 OBBBA rules apply a 0.5% AGI floor on cash donations but stock donations to DAFs remain exempt from the floor — a material consideration for Oracle or other tech employees who own large appreciated positions. See the DAF strategy guide for the full analysis.

4. Time RSU lot sales to minimize federal capital gains

Without state capital gains tax to optimize around, Tennessee tech employees can focus entirely on federal lot selection: identifying lots held for more than 12 months to qualify for LTCG rates, harvesting losses in down-market lots to offset gains elsewhere, and pairing lot sales with Roth conversions in lower-income years. For Oracle employees who received significant new grants after relocating from California, those grants have zero California sourcing — all appreciation benefit accrues at federal-only LTCG rates. See the tax-loss harvesting guide for RSU-specific wash sale rules.

5. Track California workdays carefully in the years after your Oracle or tech company relocation

Every day you physically work in California after your Tennessee domicile is established is a California workday — counted in the allocation for your pre-move RSU grants, and potentially signaling to the FTB that you haven't fully severed California ties. Keep a contemporaneous calendar log (hotel receipts, airport records, badge swipes, Slack/calendar timestamps) for any years with large vest events. For Nashville-based remote workers who occasionally travel to Bay Area or Silicon Valley offices: even a few California workdays per quarter create measurable California-sourced income on grants still in their vesting window.

6. Model the full HCOL-to-Nashville relocation math

The financial case for relocating from California or New York to Tennessee is strongest when you include all the moving parts: the annual state income tax savings on RSU vests, the capital gains savings on subsequent share appreciation, the lower property tax on equivalent housing, and the net cost of higher sales taxes. An advisor who has modeled this for multiple Oracle or FAANG employees relocating to Nashville can map out the break-even timeline on your specific grant schedule and show you which years have the largest California nonresident filing obligation — and when it fully phases out.

What a fee-only advisor can help you model

• Your grant-by-grant California allocation after the move — exactly how much CA income you'll still owe on existing RSU and option grants, and when each grant's California claim expires
• The year-by-year tax trajectory of a California-to-Tennessee move, including part-year return complexity, nonresident filing obligations, and the payoff timeline on existing grants
• ISO exercise timing given federal AMT — and how the Tennessee no-state-AMT environment compares to California's 7% state AMT for your specific spread size
• Lot selection and hold/sell decisions for appreciated RSU tranches, ESPP lots, and any startup equity, modeled at your federal rates and concentration risk tolerance
• Estate and gift planning: using the $15M OBBBA exemption, annual exclusion gifts ($19K/recipient in 2026), and 529 superfunding with RSU vest proceeds
• The full relocation math: state income tax savings vs. sales tax costs vs. housing price differential vs. grant tail analysis — mapped to your specific compensation structure
