April 15 is quickly approaching -- only two weeks remain to file your 2018 income tax return.The Internal Revenue Service requires anyone with gross annual income greater than $12,000 ($24,000 if married filing jointly) to complete a return. Failure to file on time can result in tax penalties and interest, so it is extremely important to submit a return on time.The Fort Knox Tax Center will be open up to April 15. We have appointment slots available from 9 a.m. to 3 p.m. on Mondays, Wednesdays and Fridays, and 11 a.m. to 5 p.m. on Tuesdays and Thursdays. We also accept walk-ins on Tuesdays and Fridays. If you have not done so already, please be sure to book an appointment soon as slots are filling up quickly.So far this year, the Tax Center has prepared over 2,500 returns, generating more than $3 million in tax refunds and saving taxpayers over half a million dollars in preparation fees.If you think you may need to file an extension, the tax center can also help with that. Service members who were deployed to combat zones may receive a deadline extension of 180 days from the day they returned from the deployment plus the number of days remaining in the tax filing season from when the member departed.Service members who wish to claim this extension should email the IRS at combatzone@irs.gov and provide the member's name, stateside address, date of birth, and date of deployment. This also extends the deadline to make any tax payments.Those who were not deployed may also ask for up to a six-month extension by filing Form 4868 with the IRS prior to April 15. However, this extension to file does not extend the deadline to pay.Therefore, taxpayers must annotate their estimated tax liability and submit any payment believed to be owed with the extension. Otherwise, late payments could be subject to failure to pay penalties and interest.Anyone needing assistance filing an extension is encouraged to call the Tax Center at (502) 624-0044. We will do our best to assist you.
