Quarterly Estimated Tax Payments in Vermont

As a self-employed individual in Vermont, you are required to make quarterly estimated tax payments to the IRS if you expect to owe $1,000 or more in federal tax for the year. These payments cover both your self-employment tax and your federal income tax liability. Failing to make timely estimated payments can result in underpayment penalties.

In addition to federal estimated payments, Vermont requires separate state estimated tax payments. You should check with the Vermont Department of Revenue for specific thresholds and forms. Most states follow a similar quarterly schedule as the IRS, but some have slightly different deadlines or thresholds.

Federal quarterly estimated payments are made using IRS Form 1040-ES. The due dates for 2025 are:

In practice, if your income varies seasonally, you can use the annualized income installment method (IRS Schedule AI) to adjust your payments. Many self-employed workers in Vermont set aside 25-30% of each payment received into a dedicated tax savings account to ensure they have sufficient funds when quarterly deadlines arrive.
