Los Angeles Equity Compensation CPA: 5 Questions to Ask First

Your employer withheld tax when your RSUs vested, and that is exactly why many people get a surprise in April. A Los Angeles equity compensation CPA earns the fee in the gap between what was withheld and what you owe, and the first call should show whether the CPA knows where that gap comes from.

The Sam's List partner program lists three Los Angeles area firms: Doug Johnson CPA, Ever Ledger in Los Angeles and Good Operator in West Hollywood. Only Doug Johnson CPA is written up here, because its profile lists equity compensation as a specialty. Every firm named is a vetted Sam's List member. The firm written up below is a paid featured member of Sam's List. How we picked this list is at the end.

1. Does Your Los Angeles Equity Compensation CPA Do This Every Filing Season?

You want to hear "every season," with examples of the mix of RSUs, options and ESPP shares in recent client files.

The same shares can show up on a W-2 (as income), on a broker statement and on Form 8949, and each document tells part of the story. A CPA who reconciles those three often spots a mismatch quickly. One who does it once a year may find it after you have filed. Ask whether the person who will do your return is the person who did those.

The limitation: volume is not proof of quality. Treat the answer as one signal and ask for a client reference.

2. How Do You Handle the RSU Withholding Shortfall?

When RSUs vest, the value is wages. Employers usually withhold federal income tax on that income at the flat supplemental rate: 22 percent on supplemental wages up to $1 million in a year, and 37 percent on the portion above that. Your actual federal tax depends on your total income and bracket, so if your bracket is higher than 22 percent, the withholding falls short. That is the RSU withholding shortfall.

The bill arrives with your return and can be large when several vests land in a high-income year. A good CPA estimates the gap before year end and tells you whether to raise your W-4 withholding or make an estimated payment. California has its own withholding and tax, so ask about the state side too.

The limitation: any estimate rests on income you have not yet earned and a share price you do not control. A projection is a planning range, not a promise.

3. How Do You Track Basis Across RSU Vests, ESPP and Option Exercises?

Ask this one slowly, because it is where overpayment hides.

When you sell shares, your broker reports the sale on Form 1099-B. For many RSU, ESPP and option shares, the basis shown there can leave out income already taxed on your W-2. If nobody corrects it, you pay tax on the same income twice. The fix is an adjustment on Form 8949 that reflects the true basis.

A CPA who handles this well keeps a record by lot: vest date, price on that date, purchase date, shares sold. If the answer is "we use what the broker sends," keep looking.

The limitation: records for old grants can be incomplete after a job change or a new plan administrator. A CPA can only reconstruct basis from what you can still obtain.

4. Will You Model AMT Before an ISO Exercise?

This is the question for incentive stock option holders, and the heart of ISO vs NSO tax planning.

Exercising a non-qualified option (NSO) generally creates ordinary income on the spread between your strike price and the share value. Exercising an incentive stock option (ISO) generally creates no regular income at exercise, but the spread can count for the alternative minimum tax (AMT). Whether you owe AMT depends on your whole return, and holding periods affect how the later sale is taxed. ESPP shares have their own holding period rules, so ask about those as well.

The useful CPA runs your numbers before you exercise, shows the AMT result at several exercise sizes and explains any credit that may be available in later years.

The limitation: if the share price falls after you exercise, you can owe tax on a gain that no longer exists. A model does not remove that risk.

5. Who Coordinates With the Financial Advisor and the Plan Administrator?

Equity compensation sits across three desks. The plan administrator holds grant and vest data. The financial advisor, if you have one, usually advises on when to sell. The CPA decides how it is taxed. When they never talk, you are the messenger.

Ask how the CPA gets documents from the plan administrator, whether they will speak to your advisor with your permission, and when in the year they review. A useful answer includes a calendar, such as a check in the fall and another after any large vest or sale.

The limitation: a CPA is not a financial advisor, and a tax answer does not tell you whether to hold concentrated stock.

Doug Johnson CPA: A Los Angeles Equity Compensation CPA on Sam's List

Doug Johnson CPA is based in Los Angeles and was founded in 2024. Its profile lists equity compensation, high net worth individuals, growing companies and small business owners among its specialties, and positions the firm for growing businesses and for high earners with equity compensation. It has three employees, serves clients nationwide, and lists minimums of $250,000 of income and $250,000 of revenue.

Doug Johnson CPA has 15 verified client reviews on Sam's List as of 2026-10-02. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences and do not represent an endorsement by Sam's List. Doug Johnson CPA is a paid featured member of Sam's List. Ratings and rankings are not indicative of future performance or results.

The limitation, plainly: a three-person firm founded in 2024 has a short track record and finite capacity in filing season, and the income minimum may not suit every employee with a small grant. Being in Los Angeles does not make a firm right for you, since it serves clients nationwide.

Frequently Asked Questions

Do I need a CPA for RSUs, or is my tax software enough?

Software can handle simple cases, but it relies on what you enter. The common failure is a 1099-B basis that omits income already taxed on your W-2. With several vests, a sale, ESPP shares or options, a CPA review is worth considering.

Why did I owe tax when my employer already withheld on my RSUs?

Supplemental withholding is a flat federal rate, 22 percent up to $1 million of supplemental wages, not your actual bracket. If your income puts you in a higher bracket, the withholding falls short and the balance is due with your return. Ask a CPA to project the gap before year end.

What is the difference between ISO and NSO tax treatment?

Generally, exercising an NSO creates ordinary income on the spread, while exercising an ISO creates no regular income at exercise but can trigger the alternative minimum tax. Holding periods affect the later sale. Your outcome depends on your full return, so model it before exercising.

How We Picked This List

You should be able to check our work, so here is what we did.

The pool. The pool is the Sam's List partner program: vetted members with a live public profile. It is not a survey of every Los Angeles CPA.

The Los Angeles roster. The roster for the area is three firms: Doug Johnson CPA, Ever Ledger and Good Operator. That is the whole roster, not a shortlist, as of the date it was last checked. Rosters change, so check the directory.

Who was written up, and why. Doug Johnson CPA is written up because its profile lists equity compensation as a specialty. Ever Ledger and Good Operator are named and linked only, with no write-up and no recommendation, and nothing here says they do or do not handle equity compensation.

Ranked or not. This is a list of questions, not a ranking. The numbering is the order we would ask them in and says nothing about any firm.

Paid listings. Listing on Sam's List is free, and so is being named in this article. The firm written up here is a paid featured member of Sam's List, which is why it is written up here.

Write down the answers to the five questions and compare them on each call. You can browse accountants on Sam's List and see the firm above.
