🔍 How do I locate the MD 504 county codes?
This guide explains what information is required for MD 504 subdivision/county entries and the correct format to use.
⚠️ Required Information
Subdivision code, incorporated subdivision, or county as of 12/31/2016.
If part-year resident, enter the information as of your last day of residence if not 12/31/2016.
Military who is a MD resident should fill in the physical address and county based on the address used to claim Maryland as the Home of Record with Defense Finance and Accounting Service for 2016.
📊 Step-by-Step Guide
Step 1: Use the correct code format
Use this when you need to enter the MD 504 subdivision/county information correctly.
See F1 help. The correct format is the 4-digit subdivision code, one space, then the name of the political subdivision, city, or town.
If not in subdivision, city, or town, enter the county name.
Step 2: Locate where the taxpayer lived on the last day of the taxable period
Use this when you need to determine which county/taxing area to enter.
Locate the county name and taxing area in which the taxpayer resided on the last day of the taxable period.
Step 3: Enter the subdivision code and name (or county if not in a subdivision)
Use this when you are ready to enter the final value.
Enter the 4-digit subdivision code, one space, then the name of the political subdivision, city, or town.
If not in a subdivision, city, or town, enter the 4-digit code and county name.
✅ Example
If the taxpayer was a resident living of Allegany County, you would enter:
0100 Allegany County
