For Tesla employees
Planning for Tesla employees, when one stock is most of the balance sheet.
A Tesla career pays in TSLA: RSUs that vest over about four years, an ESPP that buys more twice a year, and a 401(k) match that stops at $3,000. The result is a household whose net worth moves with one volatile stock, under an insider trading policy that bans hedging and margin. We plan around that for employees at Gigafactory Texas and at the Fremont Factory alike.
The situation
One stock, a small match, and two states
Tesla reported 134,785 employees worldwide at the end of 2025. It is headquartered at Gigafactory Texas in Austin, with the Fremont Factory and Megafactory Lathrop in California. The 10-K says the company emphasizes stock ownership, and the pay structure shows it: RSUs that vest over about four years, an ESPP with six-month offering periods, and a 401(k) match that did not exist before 2022.
The concentration is the quiet problem. Every vest adds shares, every ESPP purchase adds more, and nothing in the pay structure takes any away. Tesla’s insider trading policy, filed with the SEC, closes the usual escape hatches: no puts, calls, or other derivatives, no hedging of Tesla securities, no Tesla securities in a margin account, and caution on pledging them for loans. For an employee, diversifying means selling, on a written schedule, outside any blackout that applies, or through a company-approved 10b5-1 plan with a 30-day cooling-off.
The 401(k) tells the other half. Tesla began matching in January 2022 at 50% of contributions up to 6% of pay, capped at $3,000 a year and vested after one year of service. A $3,000 ceiling means the household’s own saving has to do more of the retirement work, and much of that saving is best done outside TSLA. And because so many Tesla careers cross the California–Texas line, the tax on each vest, each purchase, and each sale depends on where the work was done and where the seller lives.
The plan terms
Tesla equity and retirement benefits in one table
What the public filings say, as of September 2026. Grant notices, enrollment materials, and the summary plan description govern your own terms.
| Benefit | Terms in the filings |
|---|---|
| Restricted stock units | Vest over about four years, per the 10-K; each grant notice sets the exact schedule. Value at each vest is taxed as wages whether or not shares are sold. |
| Employee stock purchase plan | 85% of the lower of the offering-date and purchase-date price. Offering periods of about six months. Payroll deductions up to 15% of eligible pay. Federal law caps purchases at $25,000 of stock a year, valued at the offering-date price. The plan lets the administrator set the period dates and any per-period share limit, so confirm both in your enrollment materials. |
| 401(k) match | Since January 2022: 50% of your contributions up to 6% of pay, capped at $3,000 a year, vested after one year of service. Employees may defer up to 90% of eligible pay within the IRS limit ($24,500 in 2026, plus catch-ups). Whether the plan accepts after-tax contributions is in the summary plan description. |
| Insider trading policy | Applies to every employee and household member. No puts, calls, other derivatives, or hedging of Tesla securities; no Tesla securities in a margin account; caution on pledging. Quarterly blackouts for directors, executive officers, and employees the company identifies. 10b5-1 plans need company approval and a 30-day cooling-off for employees. |
Why it’s complex
Five Tesla-specific decisions
How much TSLA, written down
A ceiling in percent of net worth, set before the next vest, counting vested shares, unsold ESPP lots, and the next twelve months of vests. Above the ceiling, shares are sold on a schedule that respects any blackout that applies to you. Below it, new shares can be kept. The number belongs to the household; the stock’s prospects do not decide it.
Equity compensation and concentrated stockSelling under Tesla’s policy
Tesla’s insider trading policy bars every employee from puts, calls, other derivatives, and any hedging transaction on Tesla securities, from holding them in a margin account, and it advises caution on pledging. That rules out collars and prepaid forwards while you work there. What remains is selling on a written schedule, in open windows or under a company-approved 10b5-1 plan with a 30-day cooling-off, plus gifting and direct indexing around the position.
Direct indexingThe ESPP, in brief
Each six-month period buys at 85% of the lower of the opening price and the purchase-date price, with up to 15% of base pay going in and a $25,000-a-year federal cap at the offering-date price. The ESPP is often the best-paid part of Tesla equity, and the question it raises is what to do with each lot on the day it arrives.
The full ESPP guideFremont and Austin are taxed differently
California taxes the share of each RSU vest earned by California workdays between grant and vest, even after a move to Texas. ESPP ordinary income follows the same rule from offering date to purchase date. Texas has no personal income tax, and a genuine Texas resident’s later capital gains are not California’s to tax.
Planning in AustinFilling the gap the match leaves
With the match capped at $3,000, the rest of retirement saving is on the household: the full $24,500 401(k) deferral for 2026, a backdoor Roth IRA once income passes the phase-out, an HSA where the health plan qualifies ($4,400 self-only or $8,750 family in 2026), and a diversified taxable account fed by TSLA sales. California does not recognize HSAs, so the state picture differs there.
How we approach tax planningHypothetical illustration
A Tesla household’s exposure, a written ceiling, and the sale plan
Round numbers, no real prices, no forecast. A married couple filing jointly; one spouse has worked at Tesla for six years. TSLA is valued at an illustrative $250 a share throughout. The first block measures the exposure; the second shows what a written ceiling and a sale plan look like under the policy.
| Line | Amount | Note |
|---|---|---|
| Vested RSU shares still held: 1,400 at $250 | $350,000 | Basis $200,000 (value at vest, already taxed as wages); $150,000 of unrealized gain, all held more than a year |
| ESPP lots held: 480 at $250 | $120,000 | Bought over four years; some lots past their qualifying dates, some not |
| 401(k), IRAs, and other investments, diversified | $550,000 | Includes six years of 401(k) deferrals plus the capped match |
| Home equity and cash | $480,000 | |
| Net worth, and TSLA as a share of it | $1,500,000; TSLA $470,000, or 31% | Unvested RSUs due in the next 12 months add another $150,000 of exposure not yet counted |
| Written ceiling: 15% of net worth | $225,000 | Set by the household, not by a view on the stock; reviewed annually |
| Excess to sell over 12 months | $245,000, in four quarterly sales of about $61,000 | Sales fall in open windows or run under an approved 10b5-1 plan adopted at least 30 days before the first trade; no collar, forward, or margin loan is available under the policy |
| New shares | Sold as they arrive | RSU vests sold at vest add no tax beyond the wages already due; ESPP lots sold on purchase report the purchase-day spread as wages |
| Federal tax on selling $245,000 of the RSU shares (basis $140,000; gain $105,000) | $19,740 | 15% long-term rate plus 3.8% net investment income tax: 18.8% of $105,000. Taxable income stays under the $613,700 ceiling of the 15% rate |
| State tax on that gain | Texas $0; California $9,765 | California taxes the gain as ordinary income, at 9.3% for a joint return at this income; Texas has no personal income tax |
The point of the table is the order of operations. The ceiling is written first, in percent of net worth, so that it does not move with the stock. The sale plan is then fitted to the policy: quarterly blackouts for covered employees, the 30-day cooling-off on a 10b5-1 plan, and no hedging or margin at all. Only then does tax enter, choosing which lots to sell first (long-term RSU shares, qualified ESPP lots) and sizing the estimated payment. A household that does it in the other order, tax first, tends to hold the stock longer than it meant to.

Our approach
A plan built around a ceiling, a sale calendar, and several vest dates a year
We read the 10-K, the plan documents, and the insider trading policy before the first meeting, so the conversation starts with your share count, your vest schedule, your blackout status, and which state each dollar was earned in.
Measure the exposure and write the ceiling
Count vested shares, unsold ESPP lots, and the next twelve months of vests against total net worth. Set the ceiling in percent, write it down, and decide what happens to new shares as they arrive.
Fit the sale plan to the policy
Confirm whether you are subject to quarterly blackouts, choose open-window sales or a 10b5-1 plan submitted for company approval at least 30 days ahead, and order the lots: long-term RSU shares and qualified ESPP lots first.
True up the taxes
Compare 22% withholding on vests with the household’s actual bracket, remember that nothing is withheld on ESPP wage income, and set the estimated payment. Log each lot’s basis, purchase date, and offering date.
Settle the state question and fill the retirement gap
For a move between California and Texas, build the workday record that FTB Publication 1004 calls for and time sales and Roth conversions around the residency change. Redirect proceeds into the 401(k), a backdoor Roth IRA, an HSA where eligible, and a diversified taxable account.

Questions
Common questions from Tesla employees
Are you affiliated with or endorsed by Tesla?
No. The Financial Sciences Company is an independent, fee-only registered investment adviser. We are not affiliated with, endorsed by, or sponsored by Tesla, Inc. or its benefit plans. We work from Tesla’s public SEC filings and, with your permission, your own plan statements.
How much Tesla stock is too much?
There is no rule in the filings, and we do not set a number from a view on the stock. We set it from the household: what share of net worth can move with one company without changing the retirement date, the mortgage, or the children’s tuition. Many households land between 10% and 20% and write it down. The written number is what makes the next vest a routine sale instead of a fresh debate.
Can I sell my Tesla shares whenever I want?
Not always. Tesla’s insider trading policy applies to every employee and covers sales of RSU and ESPP shares. Directors, executive officers, and employees the company identifies are also barred from trading during quarterly blackouts that begin after the first trading day following the 15th of the quarter’s last month and end after the first full trading day following the results release, plus any special blackout. A 10b5-1 plan approved by the company and adopted at least 30 days earlier can trade through those windows.
Can I hedge my Tesla shares with a collar or a prepaid forward?
Not while you are an employee. Tesla’s insider trading policy, filed with the SEC, prohibits transactions in puts, calls, and other derivatives on Tesla securities and any hedging or similar transaction designed to reduce the risk of holding them. It also bars holding Tesla securities in a margin account and advises caution on pledging them for loans. Diversification happens through sales, gifts, and what is built around the position.
Is the Tesla 401(k) match really only $3,000 a year?
Yes, per the FY2025 10-K: since January 2022 Tesla matches 50% of contributions up to 6% of pay, capped at $3,000, vested after one year of service. Employees may still defer up to the IRS limit, $24,500 in 2026 plus catch-ups. The small match is why the rest of a Tesla household’s retirement saving, and where it goes, matters more than at employers with a full match.
I moved from Fremont to Austin. Does California still tax my RSUs?
Partly. Under FTB Publication 1004, California taxes the portion of each vest earned by California workdays between the grant date and the vest date, even if you are a Texas resident on the day it vests. Grants made after the move are not California-source. Gains on a later sale by a genuine nonresident are not California’s, and Texas has no personal income tax. Keep a workday log for the transition year.
Does the 2025 CEO award change my planning?
Not directly. Tesla’s 10-K reports that the board granted about 423.7 million shares of performance-based restricted stock to the CEO in September 2025, approved by shareholders in November 2025 and earned in 12 tranches tied to market-capitalization and operational milestones. For an employee holder it is one input to an old question: how much of the household should ride on one company. We size that answer to your balance sheet, not to a view on the stock.
