Real Estate Tax Accrual: Monthly Journal Entries, True-Ups, and the Ratable Accrual Election

September 2026  ·  CleanCRE

Property tax bills don't arrive monthly, they usually land once or twice a year as a single, often large payment. Booking that entire amount as an expense in the month it's paid makes every other month look artificially healthy and that one month look like a disaster. RET accrual exists to fix that: spreading the real cost of property taxes evenly across the months they actually cover, instead of letting the bill's arrival date distort the picture.

Here's what actually goes into doing it correctly.

The Expense Belongs To The Period It Covers, Not The Date It's Paid

This is the matching principle doing its job. Property taxes relate to a specific period of ownership and use, regardless of when the taxing authority happens to send the bill or when it gets paid. A property that's owned and generating income all year should show a property tax expense spread across that same year, not a spike in whichever month the check went out. Skipping accrual means every monthly P&L is technically wrong on a cash basis dressed up as something more meaningful.

The Monthly Entry Is Simple, But It Has To Actually Happen Every Month

Each month, the accrued portion of the annual estimated tax gets recorded as an expense with a matching entry to a liability account, accrued property taxes. When the actual bill arrives and gets paid, that payment clears the liability account rather than hitting the income statement a second time. The mechanics aren't complicated. What actually breaks this is skipping a month here and there, since a gap in the accrual schedule means the expense recognition falls behind and the eventual bill lands as a partial surprise anyway, which defeats the entire point.

Estimates Need A True-Up When The Actual Bill Comes In

The monthly accrual is built on an estimate, usually based on the prior year's assessment plus an expected increase. When the actual tax bill arrives, it rarely matches the estimate exactly. The difference, whether the accrual undershot or overshot the real number, gets trued up in the period the actual bill is known, not silently absorbed or spread retroactively across months that already closed. A true-up that goes unrecorded means the books never actually reflect what the property really owed.

Some Jurisdictions Allow A Formal Ratable Accrual Election

Under federal tax rules, an accrual-basis taxpayer can elect to accrue real property taxes ratably over the specific period they relate to, rather than on whatever date local law says the tax technically accrues. This election has real mechanics attached, when it can be made, how it interacts with taxes that straddle two different assessment periods, and it's a decision that should be made deliberately with the entity's tax preparer rather than assumed by default. It's a tax election with accounting consequences, not just a bookkeeping convenience.

Cash Vs. Accrual Tax Proration Can Move Real Money At A Sale

This matters beyond monthly bookkeeping. When a property sells in a jurisdiction where taxes are paid in arrears, whether the deal prorates taxes on a cash basis or an accrual basis changes who's actually credited for what at closing, sometimes by six figures on a single transaction. A seller on accrual basis credits the buyer for the full prior period's taxes; on cash basis, they don't. This isn't a detail to leave ambiguous in a purchase agreement, and it's exactly the kind of thing that gets missed when the accrual treatment used during ownership isn't clearly understood going into a sale.

What Good Actually Looks Like

• A monthly accrual entry recorded every month without exception, based on a reasonable current-year estimate
• The accrued liability account building up consistently, matching what's actually expected to be owed
• A true-up recorded promptly once the actual bill is known, not absorbed silently into whatever month it happened to arrive
• A deliberate decision, made with the entity's tax preparer, on whether a ratable accrual election makes sense
• Clear documentation of the accrual method in place before any property sale, since it directly affects tax proration at closing

Frequently Asked Questions

Why not just record the property tax expense when the bill is paid?

Because that makes the month the bill arrives look artificially expensive and every other month look artificially healthy. Accrual spreads the real cost across the period it actually covers, which is what the matching principle in accounting is built to do.

What happens if the accrual estimate turns out to be wrong?

The difference gets recorded as a true-up in the period the actual bill becomes known. A small miss is routine and expected; what matters is that the true-up actually gets recorded rather than quietly absorbed.

Does RET accrual affect anything beyond monthly bookkeeping?

Yes, most notably at a property sale. Whether taxes were treated on a cash or accrual basis during ownership affects how much gets credited to the buyer at closing in jurisdictions that pay taxes in arrears, and that difference can be significant.

Is the ratable accrual election something every property should make?

Not automatically. It's a real tax election with specific timing rules, and whether it makes sense depends on the entity's broader tax position. It's worth a direct conversation with a tax preparer rather than assuming it by default.
