For pharmaceutical executives approaching retirement, year-end tax planning is rarely limited to deciding whether to make one more charitable contribution or realize an investment loss.

A single tax year may include salary, a cash bonus, vested RSUs, ESPP shares, stock-option activity, deferred compensation, investment income and retirement-plan contributions. A job transition or severance payment can add another layer of complexity.

Each item may look manageable on its own. The difficulty is understanding how they interact.

A decision involving employer stock may change capital gains. A Roth conversion may affect Medicare premiums. A bonus may push income into a higher marginal bracket. A charitable gift may be more valuable in one year than the next.

That is why year-end tax planning should begin with a projection, not a list of isolated transactions.

1. Project your total 2026 income

Start by estimating every source of income that could appear on the 2026 tax return.

For a pharmaceutical executive, that may include:

  • Salary
  • Annual or long-term incentive compensation
  • Restricted stock units
  • Nonqualified stock-option exercises
  • Incentive stock-option exercises
  • ESPP share sales
  • Severance or unused paid time off
  • Deferred-compensation distributions
  • Interest and dividends
  • Capital gains and losses
  • Pension or retirement-account distributions
  • Income from a spouse
  • Consulting or other business income

Do not rely solely on your most recent pay statement. Equity compensation, investment transactions and deferred compensation may not be reflected in the same place.

The objective is to create a full-year income estimate before making additional taxable decisions.

Once that projection is complete, compare it with the income you expect during the first several years of retirement. A transaction that appears expensive in 2026 may be even more expensive later, while another decision may be better postponed until employment income declines.

2. Compare withholding with your projected tax liability

Executives often assume that taxes withheld from salary, bonuses and equity compensation will be sufficient.

That is not always the case.

Supplemental withholding on a bonus or RSU vesting is not necessarily the same as the household's actual marginal tax rate. If too little was withheld, the difference may become an unexpected tax bill.

Review:

  • Federal income tax withholding
  • State income tax withholding
  • Taxes withheld from bonuses
  • Taxes withheld when RSUs vested
  • Estimated tax payments
  • Taxes withheld from retirement or deferred-compensation distributions
  • Income earned by a spouse

If a shortfall exists, you may still have time to adjust payroll withholding, make an estimated payment or use withholding from an eligible year-end distribution.

The correct approach depends on the household's complete tax picture. The goal is not necessarily to produce a refund. It is to avoid an unnecessary surprise and manage potential underpayment penalties.

3. Review your remaining retirement-plan contributions

The 2026 employee contribution limit for most 401(k), 403(b) and governmental 457 plans is $24,500.

Employees age 50 or older may generally contribute an additional $8,000. Those turning age 60, 61, 62 or 63 during 2026 may qualify for a higher catch-up contribution of $11,250.

Beginning in 2026, employees whose 2025 wages from the plan sponsor exceeded $150,000 must generally make catch-up contributions on a Roth basis if the employer's plan offers the applicable Roth feature.

Before changing your contribution percentage, confirm:

  • How much you have already contributed
  • How many pay periods remain
  • Whether your bonus is eligible for deferral
  • Whether the plan limits the percentage contributed from one paycheck
  • Whether increasing contributions could affect the employer match
  • Whether catch-up contributions must be Roth
  • Whether a contribution election applies to salary, bonuses or both

For an executive nearing retirement, the decision is not simply whether to contribute more. You should also evaluate whether additional pre-tax or Roth savings better supports your multi-year retirement tax strategy.

4. Recalculate the tax impact of outstanding equity awards

Equity compensation can materially change the year-end projection.

Create an inventory of:

  • RSUs that vested during 2026
  • RSUs scheduled to vest before year-end
  • Vested employer shares still held
  • ESPP shares that could be sold
  • Incentive stock options
  • Nonqualified stock options
  • Unvested awards
  • Awards that could be affected by retirement or termination

RSU income is generally recognized when the shares vest, even if you continue holding the stock. A later sale creates a separate capital gain or loss based on the share value at vesting.

This distinction matters because an executive may owe ordinary income tax on the original vesting value while the shares are now worth substantially less.

Review the cost basis, holding period and unrealized gain or loss for each group of shares. Do not treat every employer-stock position as though it has the same tax history.

5. Evaluate capital gains and losses together

Review taxable investment accounts for realized and unrealized gains and losses.

A loss may offset capital gains and potentially reduce a limited amount of ordinary income. However, realizing a loss should not be treated as an automatic year-end exercise.

Consider:

  • Gains already realized during 2026
  • Losses already realized
  • Concentrated employer-stock positions
  • Mutual-fund capital-gain distributions
  • Securities you intend to sell for investment reasons
  • Charitable gifts of appreciated securities
  • The wash-sale rule
  • The household's expected tax bracket in future years

Tax-loss harvesting can be useful, but the investment strategy comes first. Selling an appropriate investment solely to create a tax loss may weaken the portfolio.

Similarly, avoiding every taxable gain can leave the household holding an overly concentrated or unsuitable position.

A coordinated Investment Management strategy should consider taxes without allowing taxes to control every investment decision.

6. Decide whether a Roth conversion belongs in 2026

A Roth conversion moves money from a tax-deferred retirement account into a Roth IRA. The taxable amount is generally included in income for the year of conversion.

The question is not simply whether you can complete a conversion before December 31.

The more important questions are:

  • What tax bracket would apply to the conversion?
  • Will additional income affect Medicare premiums in a future year?
  • Could the conversion increase the taxation of other income?
  • How would it interact with capital gains?
  • Can the tax be paid from funds outside the IRA?
  • How does the current rate compare with the expected future rate?
  • Would a partial conversion be more appropriate than a larger one?

Executives who are still receiving salary, bonuses and equity compensation may have limited room for an efficient conversion. Others may find that a lower-than-expected bonus, employment transition or early retirement creates an opportunity.

A Roth conversion should be evaluated as part of a multi-year Roth Conversion Strategy, not as a transaction that must be completed simply because the calendar year is ending.

7. Confirm required distributions and charitable transfers

Individuals subject to required minimum distributions should confirm that the full amount has been withdrawn from every applicable account before the deadline.

Do not assume that one custodian is monitoring accounts held elsewhere.

If you are at least age 70½ and charitably inclined, a qualified charitable distribution may allow funds to move directly from an eligible IRA to a qualified charity. A properly completed QCD can satisfy part or all of an RMD while keeping the qualifying amount out of adjusted gross income.

The timing and processing details matter. Beginning the transaction during the final days of December may not leave enough time for the custodian and charity to complete it correctly.

Confirm:

  • The total RMD required
  • Distributions already completed
  • Accounts held at other institutions
  • Whether a QCD is appropriate
  • Whether the charity is eligible
  • Whether the check or transfer will be completed before year-end
  • How the transaction will be documented for tax preparation

8. Coordinate charitable gifts with income and investments

If you plan to make charitable gifts, compare the available funding methods.

Potential options include:

  • Cash
  • Appreciated securities
  • Qualified charitable distributions
  • A donor-advised fund
  • Multi-year gift bunching

Donating appreciated securities may allow an eligible taxpayer to support a charity without first realizing the embedded capital gain. A donor-advised fund may be useful when the deduction is valuable in the current year but grants to individual charities will occur over time.

The size, timing and form of the gift should reflect both charitable intent and the household's tax circumstances.

Do not let a potential deduction determine whether you make a gift. Start with the amount and organizations you want to support, then determine the most tax-efficient way to fund that decision.

9. Review health savings account activity

If you are eligible to contribute to a health savings account, confirm that contributions are on track and within the applicable limit.

Also review:

  • Employer contributions
  • Payroll contributions
  • Contributions made outside payroll
  • Coverage changes during the year
  • Medicare enrollment
  • Prior-year HSA reimbursements
  • Receipts for qualified medical expenses

HSA contribution eligibility generally ends when Medicare coverage begins. Because Medicare Part A can sometimes apply retroactively, someone approaching Medicare should coordinate the final HSA contribution carefully.

An HSA can be a valuable long-term retirement asset when contributions, investments and future reimbursements are managed intentionally.

10. Consider how 2026 income may affect future Medicare premiums

Medicare income-related surcharges generally use tax-return information from two years earlier.

That means decisions affecting 2026 modified adjusted gross income may influence Medicare premiums in 2028.

Potential income sources include:

  • Roth conversions
  • Capital gains
  • RSU vesting
  • Employer-stock sales
  • Deferred compensation
  • Retirement-account distributions
  • Business income

This does not mean income should always be kept below an IRMAA threshold. Paying a higher Medicare premium may be reasonable when a transaction produces a larger long-term benefit.

The important point is to identify the Medicare consequence before completing the transaction.

11. Revisit deferred compensation and benefit elections

Nonqualified deferred-compensation plans often require elections well before the compensation is earned or distributed.

Review:

  • Upcoming election deadlines
  • The amount being deferred
  • Distribution dates
  • Lump-sum versus installment elections
  • Separation-from-service provisions
  • Employer credit risk
  • Expected income during distribution years
  • The effect on retirement cash flow and taxes

A deferral may reduce current taxable income, but it also creates taxable income in a future year. That future income could overlap with Social Security, pensions, RMDs, Roth conversions or Medicare.

The decision should support the retirement income plan, not merely reduce this year's tax bill.

12. Check beneficiary, estate and account details

Year-end tax planning often reveals administrative issues that are not strictly tax matters but can still affect the plan.

Confirm:

  • Beneficiary designations
  • Account ownership
  • Trust and estate-plan coordination
  • Charitable beneficiaries
  • Transfer-on-death instructions
  • Outstanding 401(k) loans
  • Equity-plan contacts
  • Current addresses with former employers and custodians

These details become especially important when retirement or a career transition is approaching.

Your estate documents, account titles and beneficiary designations should tell the same story.

13. Build the first version of your 2027 tax plan

Good year-end planning should not end on December 31.

Use the 2026 projection to identify decisions that may require action early in 2027:

  • Adjusting payroll withholding
  • Changing retirement-plan contributions
  • Planning estimated tax payments
  • Scheduling equity sales
  • Preparing for RSU vesting
  • Coordinating deferred-compensation distributions
  • Evaluating Roth conversions
  • Planning charitable gifts
  • Preparing for retirement or a job transition

This turns tax planning from a December scramble into an ongoing process.

Frequently Asked Questions

Why might bonus or RSU withholding be insufficient?

Bonuses and equity compensation may be subject to supplemental withholding rules that do not match the household's marginal tax rate. Other income, deductions and a spouse's earnings also affect the final tax liability. A full-year projection is the best way to identify a potential shortfall.

Should I sell employer stock before year-end?

The decision depends on concentration risk, cost basis, holding period, taxes, liquidity needs and your continued reliance on the employer for income. Evaluate the shares within the complete financial plan rather than selling or holding solely because of the calendar.

Is a year-end Roth conversion always beneficial?

No. A conversion creates taxable income and may affect capital-gain taxation, Medicare premiums and other planning items. The decision should compare current and future tax rates and consider the household's multi-year retirement plan.

Should I increase my 401(k) contribution for the final pay periods?

Possibly. First confirm how much you have already contributed, how many eligible paychecks remain, whether the plan limits contribution percentages and how a change could affect the employer match. Executives eligible for catch-up contributions should also confirm whether the contributions must be made on a Roth basis.

When should year-end tax planning begin?

Ideally, the initial projection should be completed before the final weeks of December. Equity transactions, charitable transfers, plan elections and payroll changes may require processing time and coordination with several institutions.

Year-end tax planning is a coordination exercise

The value of year-end tax planning does not come from completing the longest checklist.

It comes from understanding how each decision affects the others.

For executives nearing retirement, bonuses, equity compensation, investments, retirement accounts, charitable giving, Medicare and future income should be evaluated as one coordinated system.

The objective is not simply to reduce the current year's tax bill. It is to make tax-aware decisions that strengthen the retirement plan over many years.
