You will need to enter the 1099-MISC into your tax return. You want to make sure that you file it because the timeshare company also sent a copy of this 1099 to the IRS and if you don't file it then you may get a letter from the IRS. Generally, the income on this form is subject to federal income tax and state income tax.
If you receive a Form 1099-MISC that reports your miscellaneous income and you don’t include the income on your tax return, you may also be subject to a penalty. Failing to report income may cause your return to understate your tax liability. If this occurs, the IRS may impose an accuracy-related penalty that is equal to 20 percent of your underpayment.
