Documents To Collect Before Starting Your Taxes 

Whether you’re preparing taxes yourself or seeking assistance from a professional, having all the necessary documents at hand is paramount. Try to keep all the documents in one location as you accumulate them, such as an online or paper folder, for easy access and organization. When it comes to filing a tax return, you don’t want to miss providing any information and causing errors or delays. You can also streamline the preparation process and help ensure that you take advantage of all available tax deductions and credits. 

Here’s a guide to the essential items to collect before diving into your tax preparation.¹ 

Prior year tax return 

• Having your tax return from last year on hand will remind you of certain elections made, income reported, deductions taken, depreciation schedules, carry overs, etc. If you e-filed and didn’t print a copy, retrieve your PIN to access the return. 

Income 

• W-2 tax forms from your employer(s) 

• Equity compensation arrangements including 83(b) elections, basis information, and holding periods

• 1099-R statements for retirement account distributions (such as 401(k), IRA)
