Corporations: Complete Form 1120-W to determine estimated tax payments
Because our tax system is pay as you go, many corporations need to consider using Form 1120-W as part of making estimated tax payments. Read on to learn about this form, who should use it, why it matters, and how to fill it out here!
What is form 1120-W?
Form 1120-W is described in its official title, “Estimated Tax For Corporations”. It’s a tax worksheet used to determine required installments of estimated quarterly tax payments for corporations.
Who should make estimated tax payments via 1120-W?
If your business is structured as a corporation and expected to make income that would exceed $500 in taxes per year (income tax less credits), you should use Form 1120-W to estimate your quarterly tax payments.
Some estimated payments made by S corporations are filed on Form 1120-W. S Corporations should see the main Form 1120-S instructions to determine if they need to make payments on Form 1120-W.
This tax form isn’t actually due to the IRS. Instead, it should be kept by the corporation filling out the form.
But, completing Form 1120-W is important as a corporation owner, as it helps you calculate your estimated payments. Completing this form matters because it helps regulate your cashflow, while also making sure you stay on top of your tax obligations.
