Rick Accounting Inc. — Tax season timeline (reference) ====================================================== January – early February - Organizers and document requests may go out as prior-year forms arrive. - Upload W-2s and early 1099s as soon as you receive them. Mid February – March - Most investment and mortgage tax forms (1099-B, 1099-DIV, 1098, etc.) arrive. - Schedule a review meeting if you have brokerage activity or multi-state items. April (federal due date window) - Finalize missing items at least one week before the filing deadline when possible. - Extensions: filing an extension extends time to file, not necessarily time to pay tax due. - Confirm e-file authorization and any state-specific steps with your preparer. After April - Amended returns only when correcting material errors or late-received forms. - Estimated tax planning for the current year if self-employed or with uneven income. This timeline is general information, not personal tax advice. Your preparer will confirm dates that apply to you.
