What documentation do I need to include when filing my state tax return?

When filing a state tax return in Utah, it is important to include specific documentation to ensure that the return is complete and accurate. Generally, taxpayers should prepare to include W-2 forms, which detail wages and withholdings from employers. Additionally, if any self-employment income is earned, 1099 forms may also be necessary. Taxpayers who have made contributions to retirement accounts or health savings accounts should have records of those contributions as well. If deductions are being claimed, such as for mortgage interest, property taxes, or certain medical expenses, taxpayers should keep receipts or relevant documentation to back up these claims. It is useful to check the current requirements on the official website of Utah State Tax Commission for any updates or changes regarding necessary documentation. This can help ensure a smooth filing process.
