The Short Answer

Compare fees, investment flexibility, consolidation benefits, and tax consequences before moving funds. A strong review asks whether the old plan has unique advantages worth keeping, whether an IRA rollover improves investment options and reduces costs, and whether consolidation improves visibility and management.

The Moment

You changed jobs and now need to decide what to do with an old retirement account.

This is a decision that often gets deferred because it feels administrative. That deferral is a mistake. Old accounts accumulate fees, lose visibility, and create complexity that compounds over time.

The Short Answer

Compare fees, investment flexibility, consolidation benefits, and tax consequences before moving funds.

A strong review asks: 1. whether the old plan has unique advantages worth keeping 2. whether an IRA rollover improves investment options and reduces costs 3. whether the new employer plan is worth using 4. whether consolidation improves visibility and management

Why This Matters

An old 401(k) sitting untouched is not neutral. It may be accumulating higher fees, limiting investment options, and creating administrative complexity. The rollover decision is also a tax event if handled incorrectly, which makes it worth doing carefully.

Decision Logic

If the old plan has low fees and strong investment options, leaving it may be reasonable. If an IRA rollover offers better options and lower costs, it is usually the stronger move. If the new employer plan is high quality, rolling into it simplifies management. Avoid cashing out โ€” the tax and penalty cost is significant. Execute as a direct rollover to avoid accidental tax withholding.

Common Mistakes

Cashing out the account and triggering taxes and penalties. Taking an indirect rollover and missing the 60-day window. Leaving the account forgotten in a high-fee plan. Rolling over without comparing the new plan's investment options and costs.

What Changes the Answer

Old plan fees, investment options, new employer plan quality, account size, and desire for consolidation.
