Notes On Data Quality

"SOI did not attempt to correct any ZIP codes listed on the tax returns; however, it did take the following precautions to avoid disclosing information about specific taxpayers: * ZIP codes with less than 100 returns and those identified as a single building or nonresidential ZIP code were categorized as “other” (99999). * Income and tax items with less than 20 returns for a particular AGI class were combined with another AGI class within the same ZIP Code. Collapsed AGI classes are identified with a double asterisk (**). * All number of returns variables have been rounded to the nearest 10. * Income and tax items with less than 20 returns within a ZIP code were excluded. * Tax returns with a negative adjusted gross income were excluded. * If an income or tax item from one return constitutes more than a specified percentage of the total of any particular cell, the specific data item for that return is excluded from that cell. For example, if the amount for wages from one return represents 75 percent of the value of the total for that cell, the data item will be suppressed. The actual threshold percentage used cannot be released. "
