There are other situations in which you have to file a tax return even if according to the general rules you would not normally need to file. These situations are as follows:
You owe any special taxes, such as the following:
Social security and Medicare tax on tips you did not report to your employer
Uncollected social security and Medicare tax on tips you reported to your employer or on group-term life insurance
Alternative minimum tax (a special tax that applies on certain “tax preference” items, or amounts that received special tax treatment)
Recapture taxes (taxes on money you got back, or recaptured, after having previously taken a tax deduction or credit)
Tax on a qualified plan, including an IRA or other tax-favored account. But if you are filing a return only because you owe this tax, you can file Form 5329 by itself
You received a payment from your employer during the year for advance earned income credit. This payment would be reported in box 9 of the W-2 form you receive from your employer.
Self-employed persons must file a return if their net earnings are at least $400, regardless of the other filing requirements. This is because of the self-employment tax (the equivalent of the Social Security and Medicare tax) they must pay.
You had wages of $108.28 or more from a church or qualified church-controlled organization that is exempt from employer social security and Medicare taxes.
