I live in Washington state. I don’t know if there was any tax credit for first time homebuyers in 2020 also each of the years that I have owned the home I did not take the standard deduction for a married couple of $25,000. Can I go back and claim that for the last three years?
Washington has no state income tax, so there cannot be any first-time homebuyer's credit or standard deduction, because there is no state tax return. It's not clear what your concern is.
If you omitted your mortgage interest and real estate tax from your federal tax returns, you can file amended returns for 2020, 2021, and 2022. But mortgage interest and real estate tax are itemized deductions. They will not give you an additional refund unless your total itemized deductions are more than the standard deduction. Here are the federal standard deduction amounts for each year for married filing jointly if both of you were under 65 years old and not blind. The standard deduction does not depend on home ownership. It's the same whether you own a home or not.
2020: $24,800
2021: $25,100
2022: $25,900
For 2018 through 2025, the total deduction for state and local taxes is limited to a maximum of $10,000 per year ($5,000 if you are married filing separately). The maximum applies to the total of real estate tax, personal property tax, and either state and local income tax or state and local sales tax. There are also limits on the mortgage interest deduction based on the mortgage balance and other factors, and the rules have changed from year to year.
To get an additional refund for 2020 you must file the amended return by April 15, 2024.
