How to fill out Form 8329, box by box
Part III Recipients of Mortgage Credit Certificates

In Part III, Recipients of Mortgage Credit Certificates, column (a): enter the name(s) of the MCC holder(s) to whom the lender made certified indebtedness loan(s) during the calendar year. If an MCC lists more than one holder, enter all of the holders on one line.
Column (b): enter the number and street, city, state, and ZIP code of the property for which the MCC was issued. Do not use a P.O. box number.
Column (c): enter the social security number(s) of the holder(s) listed on the MCC.
Part IV Computation of the Total Amount of Mortgage Credit Certificates

Match the information entered on each line of Part IV with the information entered on each corresponding line in Part III.
Column (d): enter the date the issuing authority issued the certificate for the amount included in column (e). Do not give the date the loan was made nor the date when any preliminary approval to issue an MCC was given by the issuer.
If the loan is for a reissued MCC as permitted by the regulations, the date of the reissued certificate should be given, preceded by the word “Reissued.” For example, “Reissued, July 25, 2008.”
Column (f): enter the certificate credit rate for each MCC.
The certificate credit rate is the rate specified by the issuer on the MCC. However, the rate cannot be less than 10% nor more than 50%.
For each certificate amount listed in column (e), multiply by the certificate credit rate associated with that certificate shown in column (f).
Line 6 Total amount of MCCs issued

Line 6 is the aggregate amount of MCCs issued (Part IV, column (g)) in connection with the lender's loans relating to the issuer's MCC program for the calendar year. The total should reflect all of the MCCs described on the lender's Form 8329, including any attachments, for the MCC program for the calendar year.
The aggregate amount (the certified indebtedness times the certificate credit rate for each MCC, totaled for all mortgage credit certificates issued under a single MCC program), may not exceed 25% of the nonissued bond amount for which the election not to issue bonds was made.
Paid Preparer Use Only

Generally, anyone who is paid to prepare a return must sign it and fill in the other blanks in the Paid Preparer Use Only area of the return. A paid preparer cannot use a social security number in the paid Paid Preparer Use Only box. The paid preparer must use a preparer tax identification number (PTIN).
The paid preparer must: sign the return in the space provided for the preparer's signature, enter the preparer information, and give a copy of the return to the lender.
Under Paid Preparer Use Only: anyone who prepares the return but does not charge the organization should not sign the return. Certain others who prepare the return should not sign. For example, a regular, full-time employee of the lender, such as a clerk, secretary, etc., should not sign.
More rules for Form 8329

If your situation is different
You report more than 5 certificates
If the lender must report on more than 5 mortgage credit certificates, it should report these additional certificates on an attached statement formatted like Form 8329.
Instead of formatting its own statement, the lender may use one Form 8329 as a transmittal document and use additional Forms 8329 as statements.
In such a case, draw an “X” across the 5 lines of Parts III and IV of the Form 8329 used as a transmitting document.
Complete the remainder of this Form 8329, making certain that all mortgage credit certificate amounts reported in all the statements in Part IV, column (g) are totaled for line 6 of the transmittal document.
Sign only the transmittal Form 8329 and indicate in the top margin the number of Forms 8329 attached to this Form 8329.
On the attached Forms 8329, show the lender's name and employer identification number in Part I and enter mortgage credit certificate information on the 5 lines of Parts III and IV.
