Six Year-End Financial Moves That Could Shape 2026 Taxes and Retirement Savings

With 83% of U.S. adults reporting financial stress, strain or uncertainty, year-end planning has a practical role beyond tax preparation. A national study by Edward Jones and Gallup, released in June 2026, found that just 16% feel financially fulfilled. For households assessing their finances, several decisions before Dec. 31 can affect taxable income, retirement balances and the timing of future tax bills.

The choices depend on income, age, account rules and access to workplace benefits. The figures below apply to 2026, and each account type follows different contribution and withdrawal rules.

Workplace plans and IRAs

Employees enrolled in a 401(k) or 403(b) can review payroll contributions before the year closes. Pre-tax contributions generally reduce current taxable income. The 2026 employee contribution limit is $24,500, rising to $32,500 for people age 50 or older. For eligible participants ages 60 through 63, a plan that permits the super catch-up allows a potential total contribution of $35,750.

A separate 2026 provision affects some higher-paid employees: those with more than $150,000 in 2025 Social Security wages from the employer sponsoring the plan generally must make catch-up contributions as after-tax Roth contributions. Employees should check how their plan applies the provision and whether payroll deductions can still be adjusted. Where an employer matches contributions, contributing enough to receive the available match can add employer funds to retirement savings.

IRAs offer another route, either alongside a workplace plan or on their own. The 2026 limit across all IRAs is $7,500, plus a $1,100 catch-up contribution for people age 50 or older, for a total of $8,600. Eligibility to deduct traditional IRA contributions depends on income and circumstances. Traditional IRA contributions may reduce taxable income now, with tax generally due on withdrawals. Roth IRA contributions use after-tax money and aren’t deductible, while qualified withdrawals and account growth can be tax-free.

IRA contributions for 2026 can be made until Tax Day. Still, contributing during the calendar year may make household cash flow and recordkeeping easier to track. Even a contribution below the annual limit adds to savings.

Tax timing inside retirement accounts

For savers with substantial pre-tax balances in traditional IRAs, 401(k)s or 403(b)s, a Roth conversion shifts eligible funds into a Roth IRA. The taxable portion converted is generally included in income for the year, while future growth and qualified withdrawals can be tax-free. The tradeoff is an immediate tax bill in exchange for a different tax treatment later.

A conversion may fit someone who expects a higher tax bracket in the future, but the added income can also affect Medicare premiums or other income-based benefits. One approach described in the source is “filling your tax bracket”: converting only enough eligible pre-tax money to remain below the top income threshold of the current bracket. Roth IRAs also aren’t subject to required minimum distributions during the account owner’s lifetime, unlike tax-deferred retirement accounts.

Required minimum distributions call for a separate year-end check. People already taking RMDs generally need to complete their 2026 distribution by Dec. 31. Anyone who turned, or will turn, 73 during 2026 must begin annual withdrawals from tax-deferred retirement accounts. The first distribution can be delayed until April 1, 2027, but doing so means taking two distributions during 2027, potentially increasing taxable income enough to reach a higher tax bracket.

The penalty for missing an RMD is 25% of the amount that should have been withdrawn. It may fall to 10% if the shortfall is corrected within the applicable correction period, and relief may be available for reasonable errors. Account holders should confirm both the amount and deadline with their plan or account provider.

Taxable investments and medical savings

Tax-loss harvesting may help investors use losses in a taxable brokerage account. Selling an investment that has declined since purchase can create a realized capital loss. Losses first offset capital gains; if losses exceed gains, up to $3,000 of remaining losses can offset other taxable income. Any excess carries forward to the next tax year.

The sale must occur by Dec. 31 to count for the 2026 tax year. The wash-sale rule can disallow the deduction if substantially identical securities are bought within 30 days before or after the loss sale. That restriction makes the timing and replacement investment relevant to the tax result.

For people eligible to contribute to a health savings account, an HSA can set aside money for qualified medical expenses while reducing taxable income. The 2026 contribution limit, counting employer contributions, is $4,400 for individual coverage and $8,750 for family coverage. Those age 55 or older may contribute an additional $1,000. HSAs provide a federal tax advantage at three points: contributions, account growth and withdrawals for qualified healthcare costs are tax-free. Contributions may be made until Tax Day, though calendar-year contributions can be easier to budget and monitor.

These six decisions involve different deadlines and tax effects, so a year-end review should account for the full household picture: income, employer benefits, account balances, age and expected medical costs. A CPA can help evaluate how the choices fit together and prepare a tax return that captures eligible credits and deductions.
