What percentage of social security would be taxable if benefit is 44K and adjusted retirement pension was 65k this year

[Coleen3]

Probably 85% or close to it.

According to the IRS, the quick way to see if you will pay taxes on your Social Social Security income is to take one half of your Social Security benefits and add that amount to all your other income, including tax-exempt interest. This number is known as your combined income (combined income = adjusted gross income + nontaxable interest + half of your Social Security benefits).

If your combined income is above a certain limit (the IRS calls this limit the base amount), you will need to pay at least some tax.

The limit is $25,000 if you are a single filer, head of household or qualifying widow or widower with a dependent child. The same applies if you are married filing separately and you lived apart from your spouse for the entire tax year. The limit for joint filers is $32,000. If you are married filing jointly and you lived with your spouse for any part of the tax year, all your Social Security income is taxable.

Calculating Your Social Security Income Tax

If your Social Security income is taxable, the amount you pay in tax will depend on your total combined retirement income. However, you will never pay taxes on more than 85% of your Social Security income.

For the 2018 tax year, single filers with a combined income of $25,000 to $34,000 must pay income taxes on up to 50% of their Social Security benefits. If your combined income was more than $34,000, you will pay taxes on up to 85% of your Social Security benefits.

For married couples filing jointly, you will pay taxes on up to 50% of your Social Security income if you have a combined income of $32,000 to $44,000. If you have a combined income of more than $44,000, you can expect to pay taxes on up to 85% of your Social Security benefits.
