Pension annuity from ex spouse

[Debtforever]

I receive a monthly pension annuity from my ex who worked for the federal government. In my 1099-R it states unknown in the box for taxable amount. Are taxes taken out prior to distribution or do I report the yearly income and get taxed when filing?

You pay tax on the full distribution amount.   

You didn't actually pay the tax.  You had taxes withheld like from your paycheck. You still have to enter the 1099R and whole gross original amount (before taxes were withheld) with your other income to figure out the total tax (and it may put you into a higher tax bracket) and then the withholding is subtracted from the total tax to figure your refund or tax due.  The gross amount shows up,on 1040 line 4a or 5a and the taxable amount on 4b/5b. The withholding will show up on 1040 line 25b.
