One good thing about the tax cuts in the new law is that most people won't have to wait long to start seeing the savings. Employers have generally lowered the amount of federal tax withheld from their workers’ paychecks, reflecting lower tax rates for most people and a larger standard deduction for married couples. The Treasury is mailing checks to most people who claimed the Child Tax Credit last year, as an advance payment of the credit’s increase. If you claimed this credit on your 2002 tax return, you may be eligible for up to $400 for each qualifying child. That’s the difference between the old maximum credit of $600 and the new amount of $1,000.

You do not have to do anything to get these benefits. Your employer adjusts your paycheck withholding based on the W-4 form you had on file. The IRS will figure if you’re entitled to any advance Child Tax Credit payment and have it sent straight to your mailbox – automatically! You don’t have to call, apply or fill out another form.

Some other changes aren’t so automatic, but could also mean extra money in your pocket. Lower tax rates for long-term capital gains and qualifying dividends may allow you to reduce your estimated tax payments for the rest of the year. An increase in the Alternative Minimum Tax exemption may insulate you from that computation. Business owners may claim larger first-year depreciation allowances and Section 179 expensing amounts.
