You will get increased speed, security, and convenience. By e-filing and selecting direct deposit, you neither need to worry about your check getting lost or stolen in the mail, nor you need to go to the bank to deposit it. Errors delay refunds and to avoid them is to e-file. Electronic filing with Direct Deposit is the fastest way to get your refund; the refund goes directly into your bank account (either checking or savings account). This is the quickest way to get your refund from the federal and state.
You can still use direct deposit even if you file a paper tax return. Make sure that you enter the correct bank account and routing number.
In case you owe the IRS, you can authorize the IRS to electronically withdraw the money directly from your bank account.
You can deposit your refund into accounts in your own name, your spouse’s name or both. Some banks require both spouses’ names on the account to deposit a tax refund from a joint return.
You can check the status of your refund on the IRS website. You will need to have the primary SSN on the return, filing status, and exact refund amount.
According to the IRS, "Taxpayers who claim the Earned Income Tax Credit or the Additional Child Tax Credit may experience a refund hold. According to the Protecting Americans from Tax Hikes (PATH) Act, the IRS cannot issue these refunds before mid-February. The IRS expects the earliest EITC/ACTC related refunds to be available in taxpayer bank accounts or debit cards starting Feb. 27, 2018, if they chose direct deposit and there are no other issues with the tax return."
