Roth means after-tax, so tax is paid now and qualified withdrawals follow Roth rules. The test uses wages from the same employer, not total pay from all jobs. Affected workers should confirm last-year wages with payroll and ask the plan how Roth catch-up elections work. Making the switch early avoids rejected pre-tax elections and missed savings.
Health savings and Medicare for open enrollment
The Journal of Accountancy, reporting on IRS Revenue Procedure, states the IRS already set 2027 HSA limits at $4,500 self-only and $9,000 family, up from $4,400 and $8,750 in 2026. An HSA is a tax-advantaged account paired with qualifying health coverage. The age-55-plus catch-up stays at $1,000, which matters for fall open-enrollment choices and retirement health savings. CMS set the 2026 standard Medicare Part B premium at $202.90 monthly with a $283 deductible.
IRMAA surcharges, which are extra premiums tied to higher income, start above $109,000 single and $218,000 joint based on 2024 MAGI. Medicare open enrollment runs Oct. 15-Dec. 7, 2026 for Jan. 1, 2027 coverage, according to Medicare.gov.
What to watch before year-end
MoneyNest reported that as of Oct. 16-20, 2026, the IRS had not published official 2027 401(k) and IRA limits, normally issued in late October-November. That means $25,500 401(k) projections remain planning-only and should not set payroll elections.
LPL Financial notes SECURE 2.0 keeps RMD age at 75 for those born in 1960 or later, versus 73 for 1951-1959. RMD means required minimum distribution, the minimum yearly withdrawal from many retirement accounts. Readers born near those cutoff years should confirm birth-year rules with the plan administrator or tax adviser. Hold 2027 contribution changes as draft until the IRS publishes the official limits.
