If you’re self-employed and don’t have paycheck withholding, you probably have to make estimated tax payments. These payments must be sent to the IRS on a quarterly basis. The 4th 2020 estimated tax payment deadline for individuals is Friday, Jan. 15. Even if you do have some withholding from paychecks or other payments, you may still have to make estimated payments if you receive income such as Social Security, prizes, rent, interest and dividends. Generally, taxpayers send four equal installments. But people who earn income unevenly during the year (for example, from a seasonal business) may be able to send smaller payments.
