What a T/I payment is and why your lender requires it

A T/I payment is the portion of your monthly mortgage bill that covers property taxes and homeowners insurance. Your lender collects this money from you each month, holds it in an escrow account, and pays the bills on your behalf when they come due. This protects the lender's investment — if your taxes or insurance lapsed, the property could be seized or damaged, leaving the lender with an unsecured loan.

Most lenders require T/I escrow as a condition of the mortgage, especially if you put down less than 20 percent. Some lenders offer the option to pay taxes and insurance yourself, but this is rare and usually only available to borrowers with strong credit and substantial equity.

Your total monthly payment breaks into four parts: principal, interest, taxes, and insurance — often called PITI. The principal and interest go toward paying off the loan itself. The T/I portion sits in escrow until the bills arrive.

Key Takeaways

  • T/I payments are collected monthly and held in escrow to pay your property taxes and homeowners insurance when bills arrive.
  • Your lender calculates the monthly T/I amount by estimating annual taxes and insurance, then dividing by 12.
  • The escrow amount changes when tax assessments rise, insurance premiums increase, or your coverage changes.
  • You receive an annual escrow statement showing what was collected, what was paid out, and what remains in the account.
  • If the escrow account runs short, your payment increases; if it has a surplus, your payment may decrease or you may receive a refund.

How the escrow amount is calculated and what causes it to change

Your lender estimates your annual property taxes and homeowners insurance costs, adds them together, and divides by 12 to get your monthly T/I payment. If your home is assessed at $300,000 and your local tax rate is 1.2 percent, that is $3,600 per year, or $300 per month. If your insurance premium is $1,200 per year, that is $100 per month. Your T/I payment would be $400.

This amount changes when real circumstances change. A tax reassessment raises or lowers your annual tax bill. An insurance company increases your premium, or you switch to a different policy. You add flood insurance or umbrella coverage. You remove private mortgage insurance once you reach 20 percent equity. Any of these shifts the escrow calculation.

Lenders also adjust escrow annually based on the previous year's actual expenses. If the account paid out more than was collected, the lender raises next year's payment to rebuild the cushion. If the account has a surplus, the payment may drop or you may receive a refund, depending on your lender's policy and state law.

Reading your escrow statement and understanding the numbers

Once per year, your lender sends an escrow statement that shows three key numbers: the opening balance (what was in the account on January 1), the deposits collected from you during the year, the payments made to the tax assessor and insurance company, and the closing balance (what remains). The statement also lists the estimated taxes and insurance for the coming year and shows whether your payment will change.

The opening and closing balances should never be zero. Lenders are required to keep a cushion — usually one to two months of estimated payments — to cover the gap between when bills arrive and when you make your next payment. This cushion protects you from a sudden spike in your payment if taxes or insurance jump.

If the closing balance is negative, your lender may ask you to pay the shortage in a lump sum, or they may spread it across your next 12 payments. If the closing balance is large and positive, some states require lenders to refund the excess; others allow lenders to keep it as a larger cushion.

When and why your T/I payment increases

Your T/I payment rises when property taxes increase, when your insurance premium goes up, or when your lender adjusts the escrow based on the previous year's actual costs. A tax reassessment is the most common trigger — your county or municipality revalues your home, and your tax bill climbs. An insurance company raises rates across the board, or your insurer increases your specific premium because of a claim, a change in coverage, or a change in your home's condition.

You may also see an increase if you removed private mortgage insurance and your lender did not adjust the escrow calculation correctly, or if you added coverage you did not have before. Some lenders build in a buffer when calculating escrow, which means your payment is higher than the strict math requires — this protects them if taxes or insurance spike mid-year.

Increases are usually announced 30 to 60 days before they take effect, either in a letter or in your monthly statement. The notice will show the old payment, the new payment, and the reason for the change.

When and why your T/I payment decreases

Your T/I payment drops when property taxes fall, when your insurance premium decreases, or when your escrow account has built up a surplus. Tax decreases are less common than increases, but they happen when a home is reassessed downward, when you successfully appeal a tax assessment, or when a local tax rate is cut. Insurance premiums may fall if you switch to a cheaper insurer, if you raise your deductible, or if your insurer lowers rates.

A surplus in the escrow account usually builds when the lender overestimated taxes or insurance, or when you paid off a portion of the loan and the lender did not immediately adjust the escrow. Some lenders automatically refund surpluses over a certain threshold; others require you to request one. Check your escrow statement to see whether a refund is due.

Decreases are less dramatic than increases and may not be announced as clearly. Review your escrow statement each year to catch them.

Disputing an escrow payment or requesting a review

If you believe your T/I payment is wrong, you can request that your lender recalculate it. Gather your property tax bill and your insurance declaration page, and send them to your lender's escrow department with a letter explaining the discrepancy. The lender has 45 days to respond and must show you the math behind their calculation.

Common reasons to dispute: your tax bill dropped but the lender has not adjusted the payment, your insurance company lowered your premium but the lender is still using the old rate, or you removed coverage but the lender is still collecting for it. If you recently refinanced, the new lender may have overestimated taxes or insurance based on incomplete information.

If the lender made an error, they must correct it and may owe you a refund. If the lender's calculation is correct, they will explain why and the payment stands. Keep copies of all correspondence.

The difference between T/I escrow and impound accounts

T/I escrow and impound accounts are the same thing — different lenders use different terms. Some call it escrow, some call it an impound account, some call it a reserve account. The mechanics are identical: you pay monthly, the lender holds the money, and the lender pays the bills. The term does not change how the account works or what you owe.

The only meaningful difference is state law. Some states regulate escrow accounts more strictly than others, setting caps on how much surplus a lender can hold or requiring faster refunds. If you move to a different state or refinance with a different lender, the terminology and rules may shift, but the basic function remains the same.

Frequently Asked Questions

Can I opt out of T/I escrow and pay taxes and insurance myself?

Most lenders require escrow as a condition of the loan, especially if you put down less than 20 percent. Some lenders allow you to pay on your own if you have strong credit and substantial equity, but you must request this and the lender may charge a fee. Even if you opt out, you remain responsible for paying on time — if you miss a payment, the lender can foreclose.

What happens if my escrow account runs out of money?

If the account does not have enough to cover a bill when it arrives, the lender pays the bill and adds the shortage to your next payment or spreads it across the next 12 months. This is why lenders keep a cushion. If shortages happen repeatedly, your lender will raise your monthly payment to prevent it.

Can I get a refund if my escrow account has a surplus?

It depends on your lender and your state. Some lenders automatically refund surpluses over a certain amount; others require you to request one. Check your annual escrow statement or call your lender's escrow department to ask about their policy.

Why did my T/I payment increase even though my taxes and insurance did not change?

Your lender may have adjusted the escrow based on the previous year's actual costs, or they may have discovered an error in the prior calculation. Review your escrow statement to see the reason. If you disagree, you can request a recalculation with supporting documents.

Is T/I escrow the same as PMI?

No. T/I escrow covers property taxes and insurance. Private mortgage insurance (PMI) is a separate fee you pay if you put down less than 20 percent, and it protects the lender if you default. PMI can be removed once you reach 20 percent equity; escrow typically remains for the life of the loan.
