About 3 million Form 1040-X, Amended U.S. Individual Income Tax Return, are filed annually. The IRS announced that Form 1040-X can now be filed electronically using commercial tax-filing software (IR-2020-182, 8/17/20). This filing option should simplify the process of amending returns and speed up IRS responses (e.g., refunds claimed on amended returns).
Initially, only 2019 amended returns for Form 1040 or 1040-SR can be e-filed. But the IRS is planning to improve the system, so stay tuned.
A fixed deduction allowed to every taxpayer, except those who may be claimed as a dependent by another person. Extra exemption deductions are allowed for a spouse on a joint return and for each qualifying dependent. A deduction of $3,400 is allowed for each exemption claimed on 2007 returns, but the deduction is phased out for certain high income individuals.
