Frequently Asked Questions

Starting in 2025 under SECURE 2.0, workers aged 60, 61, 62, or 63 can contribute an additional $11,250 (instead of the standard $7,500 catch-up for 50+), totaling $34,750. This is a significant planning opportunity for those in their early 60s with high income.
At minimum, contribute enough to get the full employer match — it's an immediate 50–100% return. After the match, prioritize: max TFSA/Roth IRA (tax-free growth), then return to 401(k)/RRSP for additional tax-deferred savings.
