New State Tax Filing Rules Under TCJA – Did You Know?
Historically, many states have closely modeled their income tax regulations after federal laws, allowing taxpayers to complete state returns very quickly after filing their federal forms. However, some states have not yet updated their forms and rules to comply with the sweeping federal tax code changes introduced under the 2017 Tax Cuts and Jobs Act (TCJA). As a result, in addition to any impact it has on your federal taxes, the TCJA might significantly affect procedures for filing your 2018 state tax return.
You may need to provide additional information and documentation not required for your federal returns. You may also be able to claim deductions at the state level that are no longer allowed on IRS forms, or find that certain deductions created under the TCJA cannot be claimed on your state return.
