The shutdown is taking place at a busy time for the IRS, accountants and filers.
This filing season marks the first under the Tax Cuts and Jobs Act — an overhaul of the tax code that went into effect at the beginning of 2018.
Here are your income tax changes for 2019 from CNBC.
Last year, the new tax code roughly doubled the standard deduction to $12,000 for singles and $24,000 for married couples filing jointly. The law also limited a number of itemized deductions, including placing a $10,000 limit on the amount of state and local taxes filers can deduct.
You will also be dealing with new tax forms, as the Form 1040 has been shrunken to the size of a postcard. You will still need to work through pages of schedules to calculate other tax breaks.
