I just updated the Estimated Quarterly Taxes template with the IRS’s 2026 rate information. Use the Tiller Community Solutions to install or upgrade to the latest version (1.09).

If you are more familiar than I am with tax rates and standard deductions, please take a moment to unhide the hidden area of the v1.09 template at right and validate the IRS data (especially M32-M36 and K38-P46) to ensure best-effort data-entry mistakes by me :sweat_smile: don’t derail your estimated payments.

Let me know if you see anything amiss.

Can you explain how to add items to the prorated section? Do just add lines and adjust the formula to add the new ones?

3

Noting here for those who might land on this thread with a similar query

You should be able to enter in respective values under the quarterly columns/ cells (where the dollar amounts are below, mostly highlighted in green)

hi Randy, Could you share a link to the template. It may be I’m just not familiar with how to find the templates. thanks

5

Are you able to install the Tiller Community Solutions add-on?

This is how you’d install the sheet.

I have been using tiller for months and just added a new sheet today.

I just wasn’t able it to find a link to add the quarterly tax sheet.

I will go back to where I found the new sheet I added today. Thanks
