Filing Extensions

There will be times when it just won’t be possible for you to file your taxes on deadline. Perhaps you’re having trouble getting all of your paperwork in order, are experiencing an emergency situation that’s making it difficult to complete your work, or let the date slip your mind and are now scrambling to get back on track. Don’t worry. In most cases, you can file for an extension to give you more time to submit your taxes.

If you’re unable to file your annual taxes by April 15, you can file an extension by that date instead. If you do, you will be given up to six additional months to submit your taxes. S corporations (S-corps) and partnerships can file Form 7004 and be given until September 15 to submit their annual taxes. Sole proprietorships and LLCs can file Form 4868 and take until October 15 to get their annual taxes in order.

Failure to pay your taxes and failing to not file for an extension can result in fines. You will be required to pay 0.5% of your unpaid tax bill for each month that you don’t pay. This adds up to a maximum of 25% of your total tax bill. If you continue not to pay your taxes, the IRS may choose to deduct what you owe from your future taxes, paychecks, or even repossess your property or possessions to pay back the debt. You may also face jail time for failing to pay.
