Do not file a tax return without ALL of your income documents; you must include every 2023 W-2 on the same tax return. Employers have until the end of January to issue W-2’s. Wait until you have all of your W-2’s. Clients, schools, Social Security, healthcare.gov, banks, mortgage lenders, and other financial institutions may not have tax documents like 1098’s or 1099’s available until late January/early February. ALL of your tax documents must be entered on the same Form 1040; do not file unless you have entered everything.
