You may need to make quarterly estimated tax payments if you own a sole proprietorship or an interest in a pass-through entity, which includes partnerships, S corporations and most limited liability companies. Changes in your business’s taxable income, deductions or overall tax situation may have altered your expected tax liability. A year-end projection can help you determine whether you’ll need to adjust your fourth-quarter estimated tax payment that’s due by January 15, 2027. Call us at (630) 513-6086 to review your situation.
