Question: how much tax should i have deducted from my pension?
Answer: That leaves a taxable pension adding up to $15,000 as the sole income. If there are no adjustments, then adjusted gross income will also be $15,000. The single person will be able to deduct $12,000 as a standard deduction, leaving $3,000 to get taxed. The rate is 10%, so estimated tax will be $300.
