When you set up your mortgage, your lender will ask whether you want to include property taxes in your mortgage payment. It sounds like a simple question, but it has meaningful financial implications.
Here’s what you need to know to make the right choice.
How property tax holdback works
When you opt to pay property taxes through your mortgage:
- Your lender estimates your annual property tax
- They divide it by the number of payments per year
- That amount is added to each mortgage payment
- The tax portion is held in a separate account (not applied to your mortgage)
- The lender pays your municipality directly when taxes come due
Example:
| Component | Amount |
|---|---|
| Mortgage payment (P+I) | $2,400/month |
| Property tax portion | $400/month |
| Total monthly payment | $2,800/month |
Your mortgage statement will show the tax portion separately from your principal and interest payment.
When it’s required vs optional
| Mortgage Type | Tax Holdback |
|---|---|
| Insured (less than 20% down) | Usually required by the lender |
| Conventional (20%+ down) | Usually optional — your choice |
| Renewal or refinance | Can sometimes be removed at renewal |
If you have a high-ratio/insured mortgage, you likely don’t have a choice — most lenders mandate tax holdback to protect the insurer’s interest in the property.
Pros of paying taxes through your mortgage
| Advantage | Details |
|---|---|
| Convenience | One payment covers everything; no separate tax bills to track |
| No missed payments | Lender pays on time, avoiding late fees or tax liens |
| Forced budgeting | Spreads the annual tax bill into manageable monthly amounts |
| Lender peace of mind | Ensures the property isn’t at risk of a tax sale (protects their collateral) |
| Simpler budgeting | You know your exact monthly housing cost |
This option is ideal if you prefer a set-it-and-forget-it approach to housing costs.
Cons of paying taxes through your mortgage
| Disadvantage | Details |
|---|---|
| Lost interest | The funds sit in the lender’s account earning little or no interest instead of yours |
| Overpayment risk | Lenders may overestimate your taxes, collecting more than needed |
| Less control | You can’t time your tax payments strategically |
| Adjustment hassles | If taxes increase, your payment changes mid-term (can be a surprise) |
| Harder to switch lenders | Tax account balance must be transferred or refunded at renewal |
The opportunity cost
If your annual property tax is $5,000, the lender collects this throughout the year and holds it. If you paid taxes yourself, you could hold that money in a high-interest savings account earning 3–4% until the tax bill comes due.
| Scenario | Annual Interest Earned |
|---|---|
| $5,000 in lender tax account | ~$0–$25 |
| $5,000 in HISA at 4% (average balance) | ~$100–$125 |
The savings are modest but real — roughly $75–$125 per year on an average tax bill.
Pros of paying taxes separately
| Advantage | Details |
|---|---|
| Earn interest | Keep funds in a HISA until taxes are due |
| Full control | You decide when and how to pay |
| No payment surprises | Your mortgage payment stays fixed |
| Easier at renewal | No tax account to transfer |
| Prepayment flexibility | Some municipalities offer early payment discounts |
Cons of paying taxes separately
| Disadvantage | Details |
|---|---|
| Discipline required | You must save consistently and pay on time |
| Risk of missed payment | Late property taxes incur penalties (typically 1.25%/month) |
| Large lump-sum bills | Annual or semi-annual tax bills can be $3,000–$10,000+ |
| Tax lien risk | Chronic non-payment can result in a tax sale of your property |
What happens if the lender gets your taxes wrong?
Lenders estimate your property taxes based on the most recent tax bill. But taxes can change:
| Situation | What Happens |
|---|---|
| Taxes increase | Lender adjusts your monthly payment upward (short notice) |
| Taxes decrease | Lender may reduce your payment or build a surplus credit |
| Reassessment | New construction or significant renovations trigger reassessment |
| Overpayment | Surplus is typically refunded or credited to your account annually |
| Underpayment | Lender may increase future payments to cover the shortfall |
Most lenders review tax accounts annually and adjust as needed.
How to decide
| If You… | Then… |
|---|---|
| Have a high-ratio mortgage | You likely must include taxes (lender requirement) |
| Prefer simplicity | Include taxes in your mortgage payment |
| Struggle to save for large bills | Include taxes — it acts as forced savings |
| Are disciplined with money | Pay separately and earn interest |
| Want maximum control | Pay separately |
| Have a conventional mortgage at renewal | Ask to remove the tax holdback if you prefer |
Can you switch?
| Situation | Can You Change? |
|---|---|
| At renewal | Yes — request removal or addition of tax holdback |
| Mid-term (insured mortgage) | Usually no |
| Mid-term (conventional mortgage) | Some lenders allow it with a request |
| Switching lenders | Tax account balance is refunded; you set up new arrangement |
If you currently have taxes included and want to switch, your renewal is the easiest time to make the change.
