Tax law changes you need to know

Tax form

The Tax Cuts and Jobs Act of 2017 (TCJA) has some of the most comprehensive tax legislation introduced in the last 30 years. From estimated taxes to withholding, changes in the law have a significant effect on your taxes. Here’s an overview of some of the major changes.

Standard deduction goes up

The standard deduction increased significantly. It’s now close to double the amounts from the 2017 tax year.

Personal exemption suspended

Beginning in 2018, filers can no longer claim the $4,050 personal exemptions for themselves or their dependents.

Child tax credit expanded

For 2018, the child tax credit increases to $2,000 up from $1,000. A new $500 credit for non-child dependents is also available. Both credits are subject to income limitations.

State and local taxes capped

Taxpayers can deduct up to $10,000 in state and local income taxes.

Mortgage interest deduction dropped

Homeowners can deduct mortgage interest up to $750,000 (previously $1 million) for loans approved after December 15, 2017. The interest deduction on home equity lines of credit (HELOC) is still available as long as the money is used to buy, build or substantially improve your home.

Tax brackets adjusted

Adjustments to the tax brackets include lowering a number of the tax rates and slightly widening the income thresholds for 2018.
