Yes. An IRA owner is allowed only one rollover per 12-month period. In 2014, the IRS changed its interpretation of this requirement to match a U.S. Tax Court ruling that a taxpayer is limited to one IRA rollover, regardless of the number or types of IRAs (Traditional, Roth and SIMPLE IRA) that the IRA owner may have. The new interpretation was effective January 1, 2015. 

The 12-month rollover rule does not apply to IRA Distributions that result from financial organization failure, the rollover of wrongful IRS levies returned to a taxpayer, as provided by the Tax Cuts and Job Act of 2017.

We are not responsible for making sure that IRA owners do not exceed this rule. This is the responsibility of the IRA owner.
