What are the possible alternatives to filing income tax late?

Yes, you'd have to pay the tax on time. It is better you calculate your probable tax amount and save that money beforehand so that you can pay on time.

Unfortunately, there is no alternative. If you fail to pay income tax on time, then you have to pay 'failure to file' penalty. You can complete Form 9465 and negotiate an installment payment plan.

You will be charged a penalty by the IRS. If you don't want to lose your hard-earned money, then pay the tax on time.

Sorry but there is no alternative for you. If you fail to submit your income tax on time, you're probably have to pay 'failure to file' penalty.
