In February 2011, the general revenue fund suffered a $1.8 million shortfall due to taxpayers finally starting to file their returns. More returns meant more refund payments.
As a result, personal income tax revenue fell $16.5 million below estimates. The state also ended up paying more in corporate tax refunds for the month than it collected, leading to a $15.8 million corporate tax deficit for the month.
But Muchow said he didn't feel the effect would be as significant this year because of the credits affected by the recent tax law changes.
The forms that will be delayed until late February or March include those tied to more obscure credits within the tax code. Those credits include residential energy credits, depreciation and amortization credits and forms tied to general business credits.
Muchow said the people who use those forms usually aren't the ones ready to file their taxes in January.
"Even under normal circumstances, nearly all of these taxpayers would file their tax returns after February anyway," he said. "Most would file close to the April 15 deadline and many would opt for extensions of time to file given some of these complex provisions."
The Jan. 30 set by the IRS applies to both paper and electronic returns. Neither will be processed before the opening date.
IRS acting commissioner Steven Miller said in a statement Tuesday that taxpayers' best option is to file electronically.
Miller said e-filing and using direct deposit for refund payments will allow taxpayers to get their refund as quickly as possible.
While the IRS delayed the opening date of this year's tax season, the change did not affect its closing date. As with past years, taxpayers will need to either file their return or file for an extension by April 15.
