    I filed a tax extension. What do I do now?

    Your Virtual CPA, a licensed CPA firm, helps self-employed people and business owners on extension gather their records and file before the extended deadline: October 15 for individuals and C corporations. An extension only extends time to file, not to pay, so interest has run since the original date. We organize 1099s, expenses and deductions with you. Book a free 30-minute call to get started.

    What an extension does and doesn’t do

    Form 4868 gives individuals up to 6 more months to file. Form 7004 generally gives businesses 6 more months. Neither one extends the time to pay.

    • Interest is charged on any tax not paid by the original due date.
    • The failure-to-pay penalty is generally 0.5% of the unpaid tax per month or part of a month, up to 25%. It drops to 0.25% per month during an approved payment plan for individuals who filed on time.
    • A separate failure-to-file penalty can apply if you miss the extended deadline. When both apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount.

    Document checklist for self-employed filers

    Best for: sole proprietors, freelancers, single-member LLC owners and consultants who extended their 2025 return.

    1. Income: all Forms 1099-NEC, 1099-MISC and 1099-K, plus income not reported on a 1099.
    2. Business expenses: a profit and loss report from your books, or bank and card statements we can categorize.
    3. Home office: square footage of the office and the home, plus rent or mortgage interest, utilities and insurance.
    4. Vehicle: a mileage log showing business miles and total miles for the year.
    5. Health insurance: premiums you paid and Form 1095-A if you bought coverage through the Marketplace.
    6. Retirement: contributions already made, and whether you want to make a SEP-IRA contribution before filing.
    7. Estimated payments: dates and amounts of federal and state estimates paid for the year, and any payment sent with the extension.
    8. Prior-year return, if we didn't prepare it.

    SEP contributions for a year can be made up to the due date of the return, including extensions. If you're on extension, that window is still open until you file or the extended deadline passes.

    Frequently asked questions

    No. An extension of time to file is not an extension of time to pay. Interest is charged on any tax not paid by the original due date, and a failure-to-pay penalty can apply as well.

    October 15 for calendar-year individuals who filed Form 4868. Form 4868 gives up to 6 more months to file. For 2025 returns, that is October 15, 2026.

    Form 7004 generally gives 6 more months to file. For calendar-year partnerships (Form 1065) and S corporations (Form 1120-S) the extended date is September 15. For calendar-year C corporations (Form 1120) it is October 15. Form 7004 does not extend the time to pay.

    Generally 0.5% of the unpaid tax for each month or part of a month it stays unpaid, up to 25%. For individuals who filed on time, it drops to 0.25% per month during an approved payment plan. Interest is charged separately.

    Yes, if your return is on extension. SEP contributions for a year can be made by the due date of the return, including extensions, and a SEP plan can be set up as late as that date too.

    File by the extended deadline anyway, since a separate failure-to-file penalty can apply if you miss it. Then look at payment options such as a short-term extension to pay or an installment agreement.
