When can seniors stop paying federal tax in america

This question often arises to senior citizens’ minds, ‘Do seniors ever stop paying federal taxes?’. The answer is one cannot exclude themselves from paying taxes, regardless of their age. Understanding the justifications for continuing to tax seniors, the average taxes they pay, and how to lower their tax liability are essential.
What age is the last to file taxes?
As per Internal Revenue Service, tax obligations in the United States are not based on a person’s age, and there is no age at which people are excused from paying taxes. If someone’s gross income exceeds $14,700 and they are 65 years of age or older, they must file a tax return. The minimum filing amount is $28,700 for married couples who are both 65 years of age or older. The limit is $27,300 if the person is married and filing jointly, but only one spouse is 65 or older.
There is one situation, though, in which seniors can say goodbye to tax files. Seniors won't owe taxes if Social Security benefits are their only source of income. They probably won't need to submit a tax return either.
Sources of taxable income for seniors
Taxable income for seniors comes from a variety of sources, including:
Investments
Seniors' sources of taxable income include interest, dividends, and capital gains. It's important to note that there is an exemption with tax-free interest from municipal bonds.
Wages
If a person above the age of 65 keeps working in a salaried position, then the income from such employment is taxable. However, social security and medicare deductions continue to apply to wages earned after age 65.
Social security
The taxpayer's overall income determines whether social security benefits are taxable. The amount of social security income included in taxable income grows as a taxpayer's income from sources other than social security rises. 
Other revenue
Earnings from partnerships or other closely held enterprises, rental income, royalties, or other company income are examples of additional sources of income for seniors.
Seniors' non-taxable income
Seniors have access to non-taxable income, which includes life insurance payouts, interest on municipal bonds, and particular government programmes like TANF (Temporary support for Needy Families) or housing support.
