The government shutdown is likely to impact tax returns if it continues through the middle of January.

During shutdowns, the IRS often doesn't perform audits, pay refunds or offer help to taxpayers with questions.

The IRS has yet to announce when individuals and businesses can begin submitting their income tax returns.

White House officials and congressional aides were continuing shutdown discussions Sunday after emerging from the first round of weekend talks without a breakthrough.

House Speaker Nancy Pelosi has said that House Democrats plan to start approving individual bills to reopen shuttered departments, starting with Treasury to ensure Americans receive their tax refunds.

"While President Trump threatens to keep the government shut down for 'years', Democrats are taking immediate further action to re-open government, so that we can meet the needs of the American people, protect our borders and respect our workers," Pelosi said.

But there's no clear indication that those individual bills could get through the Senate or make it past President Donald Trump's desk.
