1. Set up a property tax expense account if you don't already have one. Go to Chart of Accounts, select New, choose Expenses as the account type, and pick Taxes Paid as the detail type, or use a broader Taxes and Licenses account if you'd rather keep property tax grouped with other tax expenses. Name it clearly, something like "Property Tax."
2. Find the payment in your bank feed. If you pay the county or city directly from a connected business account, the payment shows up like any other transaction.
3. Categorize it to your property tax account. Select the transaction, assign the category, confirm the payee as the taxing authority, and click Add.
4. If it's paid by check or outside the bank feed, enter it manually. Use + New > Expense or Check, choose the account it's paid from, and categorize the line to Property Tax.
5. Split it out if it's bundled into a mortgage escrow payment. When one payment covers principal, interest, insurance, and property tax together, use the Split option on the transaction so only the property tax portion lands in your Property Tax account; the rest goes to its own appropriate categories.
6. Set up a rule for recurring payments. If the same taxing authority bills you annually or semi-annually, a bank rule under Rules can categorize future payments from that payee automatically.
