What the distribution phase means and when it starts

The distribution phase is the period when you stop adding money to retirement accounts and start taking money out to live on. It typically begins when you retire, though the exact timing is yours to choose — you can retire at 55, 67, or 72, and the rules change depending on your age and account type.

During the accumulation phase, you contributed to accounts like 401(k)s, IRAs, and taxable investment accounts. In the distribution phase, those accounts become your income source. The shift matters because the tax rules, withdrawal limits, and penalties change dramatically. A withdrawal that costs you nothing in penalties at 72 might cost you 10 percent if you take it at 60.

The distribution phase is not a single moment — it is a 30-year or longer period with different rules at different ages. Understanding those rules before you retire prevents costly mistakes.

Key Takeaways

  • You can withdraw from most retirement accounts without penalty starting at age 59½, but some accounts have different rules and some withdrawals trigger taxes immediately.
  • At age 73, you must begin taking required minimum distributions (RMDs) from traditional IRAs and 401(k)s, or pay a 25 percent penalty on the amount you should have withdrawn.
  • Social Security and pension income are taxed differently than investment withdrawals, and the order in which you draw from different accounts affects your total tax bill.
  • Roth IRAs and Roth 401(k)s have no required withdrawals during your lifetime, making them useful for leaving money to heirs or delaying taxes.
  • The first year you take distributions is when you are most likely to make a costly error, so reviewing your plan with a tax professional before you retire saves money.

How taxes work when you start withdrawing money

Taxes on retirement withdrawals depend on what type of account the money came from. A withdrawal from a traditional 401(k) or traditional IRA is taxed as ordinary income in the year you withdraw it — the same rate as wages. A withdrawal from a Roth IRA or Roth 401(k) is tax-free if the account has been open for at least five years and you are at least 59½.

Money in a taxable brokerage account is taxed differently. If you sell stocks or funds that have gained value, you pay capital gains tax on the profit, not on the full amount you withdraw. If you withdraw money that you contributed (your cost basis), that portion is not taxed. This is why the order matters: withdrawing from a taxable account first can mean a lower tax bill than withdrawing from a traditional IRA first.

Social Security benefits are taxed based on your "combined income" — half your Social Security plus all other income. If your combined income exceeds $25,000 (single) or $32,000 (married filing jointly), up to 85 percent of your benefits become taxable. This creates a cliff: taking a large IRA withdrawal can push your Social Security into a higher tax bracket, even though the IRA withdrawal itself is only taxed once.

Required minimum distributions and the penalty for missing them

At age 73, you must begin withdrawing a set amount each year from traditional IRAs and most 401(k)s. This amount is called a required minimum distribution (RMD). The IRS calculates it by dividing your account balance on December 31 of the prior year by a life expectancy factor. For a 73-year-old, the factor is roughly 26.5, so a $500,000 account would require a withdrawal of about $18,900 that year.

If you do not take your RMD by December 31, the penalty is 25 percent of the shortfall. If your RMD was $18,900 and you withdrew nothing, you owe $4,725 in penalties alone, plus income tax on the $18,900. The penalty was reduced from 50 percent in 2023, but it remains severe enough to make a calendar reminder essential.

Roth IRAs have no RMD requirement during your lifetime. Roth 401(k)s do require RMDs, but you can roll a Roth 401(k) into a Roth IRA to eliminate the requirement. This is one reason Roth accounts are valuable in retirement — they give you control over when and how much you withdraw.

Withdrawal strategies that reduce your tax bill

The order in which you withdraw from different accounts matters. A common strategy is to withdraw from taxable accounts first, then traditional IRAs, then Roth IRAs last. This lets your Roth money grow tax-free as long as possible and delays the tax hit from traditional accounts.

Another strategy is tax-loss harvesting in taxable accounts. If you own a stock or fund that has lost value, you can sell it to lock in a loss, then use that loss to offset gains elsewhere or up to $3,000 of ordinary income. This reduces your taxable income in years when you are taking large distributions.

Some people use a Roth conversion in early retirement, before they turn 73 and RMDs begin. You withdraw money from a traditional IRA, pay income tax on it, and deposit it into a Roth IRA. This sounds counterintuitive — you are paying tax now to avoid it later — but it works if your income is low in early retirement (before Social Security and pensions kick in) and you expect to be in a higher tax bracket later. The conversion itself is taxable, so you need to plan the amount carefully.

When you can withdraw without penalty before age 59½

Normally, withdrawing from a traditional IRA or 401(k) before age 59½ triggers a 10 percent early withdrawal penalty on top of income tax. But several exceptions exist. The Rule of 55 allows penalty-free withdrawals from a 401(k) (not an IRA) if you separated from service in the year you turned 55 or later. You must withdraw from that specific 401(k); rolling it to an IRA closes this door.

The SEPP exception (Substantially Equal Periodic Payments) lets you withdraw from an IRA or 401(k) at any age without penalty, as long as you take equal amounts every year based on your life expectancy. The IRS publishes three methods to calculate the amount; you must use one consistently. If you stop the payments before age 59½, you owe the 10 percent penalty retroactively on all prior withdrawals.

Other exceptions include withdrawals for a first-time home purchase (up to $10,000 lifetime from an IRA), medical expenses exceeding 7.5 percent of your income, disability, and certain hardships. Each has strict rules and documentation requirements. Roth IRAs allow you to withdraw your contributions (not earnings) at any age without penalty, which is why some people fund a Roth early in their career even if they do not need the money — it becomes a penalty-free emergency fund.

Coordinating Social Security, pensions, and investment withdrawals

If you receive a pension or Social Security, your withdrawal strategy must account for both. Delaying Social Security increases your monthly benefit by about 8 percent per year from age 62 to 70. If you retire at 62 but do not claim Social Security until 70, you need to fund eight years of living expenses from savings. This might mean larger withdrawals from retirement accounts in early retirement, which increases your tax bill.

Conversely, if you claim Social Security at 62 and it is taxable (because your other income is high), you might reduce withdrawals from traditional accounts to keep your combined income lower. The math is individual: a tax professional can model your specific situation and show you the cost of each claiming age.

Pensions are usually fixed and taxed as ordinary income. If you have a choice between a lump sum and monthly payments, the lump sum gives you control over withdrawals but requires you to manage the money. The monthly pension removes investment risk but locks in a fixed income. This choice should be made before you retire, because you usually cannot change it afterward.

Setting up a withdrawal schedule before you retire

The best time to plan your distribution strategy is 6 to 12 months before you retire. At that point, you know your account balances, your expected expenses, and your Social Security claiming age. A tax professional can model different withdrawal scenarios and show you the tax cost of each.

Your plan should specify which accounts you will draw from each year, in what order, and how much. It should account for RMDs starting at 73, changes in tax brackets, and major expenses (a car replacement, home repair, travel). It should also include a rule for what you do if the market drops sharply — do you reduce withdrawals, or do you stick to your plan and withdraw from bonds instead of stocks?

Once you retire, review your plan annually. If your income, expenses, or tax law changes, adjust your withdrawals. Many people set up automatic monthly transfers from their brokerage to their checking account, which makes budgeting easier and removes the temptation to withdraw more in a down market.

Frequently Asked Questions

Can I take money out of my 401(k) while I am still working?

Most 401(k) plans allow withdrawals only after you separate from service (retire or leave the job). Some plans allow "in-service distributions" at age 59½ or later, but this is optional for employers. Check your plan documents or ask your HR department. If you leave the job, you can withdraw from that 401(k) regardless of age, though you will owe the 10 percent penalty if you are under 59½ unless an exception applies.

What happens if I withdraw more than my required minimum distribution?

The excess counts toward next year's RMD. If your RMD is $20,000 and you withdraw $30,000, you have satisfied this year's requirement and reduced next year's by $10,000. This is useful if you have a high-income year and want to spread withdrawals across two years. However, the entire $30,000 is taxed in the year you withdraw it.

Should I convert my traditional IRA to a Roth before I retire?

A conversion makes sense if your income is lower before retirement than it will be after (for example, you retire at 60 but do not claim Social Security until 70). It also makes sense if you expect tax rates to rise, or if you want to leave tax-assistance programs to heirs. The conversion itself is taxable, so you need enough cash outside the IRA to pay the tax bill. Consult a tax professional to model your specific situation.

What if I need more money than my plan allows?

You can withdraw more than planned, but it increases your taxable income and may push you into a higher tax bracket or make more of your Social Security taxable. Before taking a large withdrawal, consider whether the expense is one-time (in which case you might borrow instead) or permanent (in which case your plan needs to change). A financial advisor can help you decide whether to adjust your spending or your withdrawal strategy.
