Provides a rough federal (and optionally state) tax refund or amount owed estimate from basic inputs. Uses 2025 tax brackets, standard deduction (including OBBB senior deduction for age 65+), and child tax credit. Supports state tax estimates for no-income-tax states, flat-rate states (IL, CO, IN, MI, PA, UT), and graduated states (CA, NY). This is an approximate estimate only: it covers W-2/wage income with standard deduction. No itemized deductions, no self-employment tax, no capital gains. Your actual result may differ. File with TaxAct for your exact number.
