IRS had indicated that they hope to go active on Jan 30th this year. That means that they will not process even mailed-in returns prior to that date. So e-filed returns will be faster as usual since they avoid being handled by IRS employees and are therefor processed faster. Tax preparers will be able to e-file returns and have most returns back to taxpayers once again within two weeks for those who decide on the direct deposit option.
Taxpayers who will have to wait longer this year to file include, among others, those that use the following popular forms:
Form 4562 Depreciation and Amortization
Form 5695 Residential Energy Credits
Form 8396 Mortgage Interest Credit
Form 8839 Qualified Adoption Expenses
Form 8909 Energy Efficient Appliance Credit
These forms, and a few others, could delay the filing of your return until late February or early March.
