SWM 2026 Tax Filing Guide

January 30, 2026

If you are like me, you are starting to feel stress well up as the various financial institutions you use begin to send email notices that tax forms are available to you. It dawns on you that tax season is upon us, and your stomach turns as you remember how hectic previous years have been—scrambling to collect each and every tax document before the deadline. On top of that, the passwords to your banks and brokerage accounts suddenly decide not to work all at once, causing added hours of password resets, all to retrieve one form.

Tax season is a nightmare. However, there are things that you can do to make it less nightmare-ish. This guide is meant to give you tips and tricks to stay organized and smooth out the tax filing process.

Use an online password keeper

Trust me, using a password keeper will save you so much time and headache. These online tools will store all of your passwords in one place, help you create complex passwords that are hard for hackers to crack, and will auto-fill username and password fields so that you can log in at the click of a button. The only thing you have to remember is your master password. Many of these tools have built-in security and encryption measures for those who are afraid of having all their passwords in one place.

I have been using a password keeper for half a decade now, and it has cut down the time it takes to manage my passwords by nearly 80%. There are plenty of tools out there, but below are two that are highly rated by users.

1Password — best overall
Bitwarden — best-rated “free version”

Gathering tax documents

Tax documents typically become available online or are mailed to you from January to March, although some might come later. Here is the average timeline for when various tax forms become available. It is a good practice to log on to each financial company you use to double-check for stray tax forms. Many companies have switched to e-delivery only and won’t issue a physical version of your tax forms to be mailed to you.

  • January: W-2 (employer), many 1099-R forms
  • Late Jan–Feb: Brokerage consolidated 1099 packets
  • March (and sometimes later): K-1s (partnerships, RE syndications, MLPs)
  • May: 5498 (IRA) and sometimes late corrections/updates

Important note: Prioritize filing accurately over filing quickly. Sometimes, 1099 tax forms need to be corrected after the first version is issued due to a calculation error. There is no set due date for a corrected 1099 to be issued to you, so if you do get one, then it might be wise to opt for an extension.
