Many key dollar limits in retirement plans and IRAs are higher in 2020, thanks to prior-year inflation. The maximum 401(k) contribution is $19,500. Those born before 1971 can put in $6,500 more. The caps apply to 403(b) and 457 plans as well. The cap on SIMPLEs is $13,500 plus $3,000 extra for people age 50 and up. The 2020 payin cap for traditional IRAs and Roth IRAs stay steady at $6,000, plus $1,000 as an additional catch-up contribution for individuals 50 and up. But the income ceilings on ROTH IRA payins went up. Contributions phase out at AGIs of $196,000 to $206,000 for couples and $124,000 to $139,000 for individuals. Also, deduction phaseouts for traditional IRAs start at higher levels in 2020, from AGIs of $104,000 to $124,000 for couples and $65,000 to $75,000 for single filers. If only one spouse is covered by a plan, the phaseout zone for deducting a contribution for the uncovered spouse starts at $196,000 of AGI and ends at $206,000.
