No. The IRS has no dollar limit on direct deposit of refunds. However, direct deposit must only be made to accounts bearing the taxpayer’s name.
Also, In an effort to combat fraud and identity theft, new IRS procedures effective January 2015 will limit the number of refunds electronically deposited into a single financial account or pre-paid debit card to three.
The fourth and subsequent refunds automatically will convert to a paper refund check and be mailed to the taxpayer.
