What can i add on my income taxes to raise the amount i get back?

To potentially increase your tax refund, consider maximizing your deductions and credits. You can add items such as charitable donations, mortgage interest, and medical expenses (if they exceed 7.5% of your adjusted gross income). Additionally, contributing to retirement accounts like an IRA may provide tax deductions. Lastly, ensure you claim all eligible tax credits, such as the Earned Income Tax Credit (EITC) or the Child Tax Credit.
