The Bottom Line
Make a checklist of every document you expect, check them off as they arrive, and don’t file until you have everything. Filing with incomplete information leads to amended returns, delayed refunds, and potential IRS notices. Most documents arrive by mid-February — give yourself until early March to be ready, then file.
