Social Security Disability Taxes

[Longswamp]

I receive Social Security Disability. If taxable income that I receive plus 1/2 of my Social Security is more than $25,000, 50% of my disability becomes taxable. In June of last year, I transferred $25,000 from a taxable account to another taxable account, resulting in me paying all taxes on this money up to that point. If I now take $15,000 of this money for expenses, will the full $15,000 be included as "taxable income" and added to 1/2 of my social security income to determine if it is taxable or will it be treated differently since all taxes are current as of last June making any taxes due on the $15,000 withdrawn non-existent or minimal.

Thank you
