Guides
Each guide answers one question, shows the arithmetic, and ends with a conditional conclusion you can apply to your own numbers.
Every figure below is quoted from the tax authority's or the regulator's own page, with the date we checked it. Where we could not confirm a number on an official page, the guide says so rather than estimating.
How much does a 1% fee cost a 401(k) or IRA over 25 years?
A 1% annual charge costs $92,000 more than a 0.25% one over 25 years on this site's example — 12.1% of the pot. The arithmetic, and where to find your own charge.
What Are the 2026 Contribution Limits for a 401(k), IRA, Roth IRA, SEP and Solo 401(k)?
2026 limits: $24,500 for a 401(k) deferral, $7,500 for IRAs combined, $72,000 for a SEP or Solo 401(k), the Roth IRA income ranges and the Roth catch-up rule.
Does the U.S. cap 401(k) fees? No single limit — ERISA requires them to be reasonable
U.S. law sets no single federal percentage cap on 401(k) fees; ERISA requires them to be reasonable and disclosed. The UK caps one arrangement at 0.75% a year.
When Does an IRA Have to File Form 990-T for UBTI?
An IRA that receives unrelated business income becomes a taxpayer in its own right, files Form 990-T once that income reaches $1,000, and pays at trust rates.
Do the 60-day rule and 20% withholding apply to a direct 401(k) rollover?
A direct rollover avoids the 60-day clock, 20% withholding and the one-per-12-months limit. A rollover paid to the owner engages all three, in the IRS's words.
What Happens If a Self-Directed IRA Makes a Prohibited Transaction?
Section 4975 forbids transactions with particular people, not particular assets, and the consequence turns on who took part — deemed distribution, or excise tax.
How much more can a Solo 401(k) take than a SEP IRA in 2026?
A SEP IRA takes employer money only. A Solo 401(k) adds an employee deferral of $24,500 for 2026, plus a filing threshold and a Roth catch-up test a SEP never meets.
