State taxes

State support in ErgoTax

ErgoTax is designed to support both federal and state income tax preparation. Not every state is supported in the current version — check the state support matrix before relying on ErgoTax for your state return.

Most states are in the Planned phase for the 2025 testing year. The matrix will be updated as state coverage expands.

States with no income tax

The following states generally do not have a broad individual income tax return: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire taxes only certain interest and dividends income for some years. Other state or local filings can still apply.

Preparing a state return

For supported states, ErgoTax uses the data from your federal return as the starting point for your state return. Most state returns begin with federal adjusted gross income and apply state-specific additions, subtractions, credits, and rates.

Review your state return values carefully. State tax rules differ from federal rules in ways that ErgoTax may not fully account for in the current version.

If your state is not supported

If your state is marked Planned or Not supported, ErgoTax cannot generate your state return. You will need to use another method to prepare your state return — a state-provided free file option, commercial tax software, or a tax professional.

You can still use ErgoTax to prepare and generate your federal return even if your state is not supported.

Part-year and non-resident returns

Part-year resident and non-resident state returns are more complex and may not be supported even for states that have general support. Check the state support matrix for notes on partial support.
