If you're a tech worker with significant equity compensation, the difference between optimal and default tax handling can easily be $20,000-$50,000+ per year. Most engineers, designers, and product managers receive RSU grants worth more than their salary, yet apply zero strategy to the tax timing of those grants. The result: paying tax at higher rates than necessary, missing capital gains qualifications, and losing AMT credit opportunities. Here's the playbook for keeping more of what you earn.
Strategy 1: Close the RSU sell-to-cover gap. The single biggest mistake tech workers make is assuming sell-to-cover handles their RSU tax liability completely. It doesn't. Sell-to-cover withholds at the 22% federal supplemental wage rate, plus FICA and state tax. For anyone in the 32%+ federal bracket, this under-withholds by 10-15 percentage points on the RSU vesting amount.
Concrete example: a senior engineer earning $180K base receives $300K of RSU vesting in 2026. Total income places them firmly in the 32% federal bracket. Sell-to-cover withholds $66,000 federal (22% × $300K), but the actual federal liability on that $300K is $96,000 (32% × $300K). The gap: $30,000 of unpaid federal tax that becomes due at filing.
The fix is straightforward: either sell additional shares immediately at vest to cover the gap, or increase your salary withholding. Most modern equity platforms allow you to elect 'sell additional shares at vest' through HR. If you elect to sell another 10-12% of vested shares, you cover the federal gap and don't face a surprise tax bill in April. This isn't a tax saving move per se — you owe the tax either way — but it prevents the cash flow shock and potential underpayment penalties.
Strategy 2: Hold RSUs for long-term capital gains treatment on appreciation. Once RSUs vest, they're 'just stock' for tax purposes. Your basis is the vest-date FMV (which was already taxed as ordinary income). Holding for more than one year qualifies any subsequent appreciation for long-term capital gains rates (15-20% federal vs 24-37% for short-term gains taxed at ordinary income rates).
But there's tension. Holding employer stock long-term creates concentration risk — if the company stumbles, you lose income AND wealth simultaneously. The conventional wisdom is 'sell at vest and diversify.' But selling at vest sacrifices the LTCG advantage. The compromise: hold a portion of vested RSUs for over 12 months while diversifying the rest immediately. You capture LTCG savings on the held portion (roughly 5-15% of total compensation, depending on bracket) while limiting concentration risk.
Strategy 3: ISO exercise timing for AMT optimization. If you have ISOs, the bargain element at exercise is an AMT preference. Large exercises trigger AMT — additional tax owed in cash with no liquidity event to fund it. The strategy: exercise in amounts that don't push you into AMT, or exercise early in the year when you have time to do tax-loss harvesting before April if the stock drops.
Use an AMT trigger calculator (we have one) to find the maximum exercise amount that doesn't push your tentative AMT above your regular tax. This is your 'safe harbor' exercise quantity for the year. Many tech workers exercise far more than this safe harbor and create unnecessary AMT exposure. Spreading exercises across multiple years often eliminates AMT entirely on the same total exercises.
Strategy 4: ESPP qualifying disposition planning. If your company has an Employee Stock Purchase Plan (ESPP) with a 15% discount and a 6-month lookback, you're looking at a tax-advantaged purchase opportunity that most employees mishandle. The ESPP discount portion is treated differently depending on whether you have a qualifying or disqualifying disposition.
Qualifying disposition (held 2+ years from offering AND 1+ year from purchase): the discount portion is ordinary income, the rest is long-term capital gain. Disqualifying disposition (sold within either window): the entire discount becomes ordinary income, plus appreciation gets capital gains treatment based on the post-purchase holding period.
Concrete example: $25K of ESPP purchases at a 15% discount, with offering price $80 and purchase price $100. You bought shares at $68 (15% off the $80 lookback). If you sell immediately at $100 (disqualifying), the $32 per share is fully ordinary income, taxed at your marginal rate. If you hold 18+ months and sell at $130 (qualifying), only the $12 per share original discount is ordinary income, and $50 per share is long-term capital gain at 15-20%. The tax savings on a typical ESPP purchase can be $5K-$15K per year just from holding for qualifying disposition.
Strategy 5: State residency and equity comp timing. RSUs and stock options are sourced based on workdays during the vesting period. If you're considering relocating to a no-tax state (Texas, Florida, Tennessee, etc.), timing the move BEFORE major vesting events captures state tax savings.
A California-based tech worker with $400K of RSUs vesting next year would owe approximately $37K in California state tax on that vesting. If they relocate to Texas BEFORE the vest, they pay $0 California state tax on that vesting. But: California uses workday sourcing for the vesting period. If they spent 50% of the vesting period in California and 50% in Texas, half the income remains California-sourced and taxable, even after relocation. Time the move strategically to minimize California-sourced income on future vesting events.
Strategy 6: Tax-loss harvest your concentrated stock. If you have unrealized losses on diversified holdings and gains on your concentrated employer stock, harvest the losses to offset the employer-stock gains. This effectively reduces concentration without immediate tax cost.
Concrete example: you have $30K of unrealized losses across various index funds and individual stocks. Your concentrated employer stock has $50K of unrealized gains you'd like to realize for diversification. Sell the losers (realize $30K of losses), then sell employer stock with $30K of gains (offset by the losses). Net realized gain: $0. Tax cost: $0. You've reduced employer stock concentration without paying tax.
Strategy 7: 83(b) elections on early-stage stock options. If you receive non-qualified stock options or restricted stock at an early-stage company where the current value is low, consider a Section 83(b) election. This allows you to recognize the bargain element at the time of exercise (when the value is low) rather than at vesting (when the value may be much higher).
Concrete example: you receive 10,000 shares of restricted stock at $0.10 per share when the company is just getting started. If you elect 83(b), you recognize $1,000 of ordinary income immediately and pay tax on it ($300 at 30% marginal rate). All future appreciation is then capital gains.
If you don't elect 83(b), you wait until vesting. By then, the stock might be worth $10/share. The 'bargain element' at vesting is $99,990 ($100,000 - $10), all taxed as ordinary income. Tax cost: $30,000 at 30% rate. You paid 100x more tax by failing to elect 83(b).
The 83(b) election must be filed within 30 days of the grant. This is a strict deadline with no extensions. Many people miss it because the company doesn't proactively suggest it.
Combining these strategies, a tech worker with $300K of equity compensation can typically save $20K-$50K per year compared to default handling. Over a 10-year career, that's $200K-$500K of additional wealth — purely from understanding the tax structure of equity compensation and applying basic strategies. Most of these decisions are simple in concept; the difficulty is just knowing they exist.
