There are no longer any age limits on making contributions to traditional IRAs. The cap of age 70½ expired after 2019. This means that those of any age who continue to have earned income (or other income treated as earned income) can contribute to a traditional IRA for 2020 and later years. There was never any age cap on a Roth IRA.
An amount taken from income as a prepayment of an individual’s tax liability for the year. In the case of wages, the employer withholds part of every wage payment. Backup withholding from dividend or interest income is required if you do not provide the payer with a correct taxpayer identification number. Withholding on pensions and IRAs is automatic unless you elect to waive withholding.
