Paying January mortgage early could cut tax bill

No, you can't make a whole year's payments and save more. Be careful that accelerated payments don't throw you into an Alternative Minimum Tax situation.

This post is by Kay Bell at little year-end attention to your mortgage payment could lower your upcoming federal tax bill.


Unlike rent, which you pay beforehand (i.e., your Jan. 1 bill covers your stay in the rental unit for that coming month), your mortgage payments are made at the end of your occupancy period. That means your Jan. 1 mortgage statement represents interest for the month of December, making it a tax-break-eligible bill for this year.


By accelerating that payment even by just a day, you get an additional tax deduction for the interest paid.


Don't get greedy, though. You can't make your February, or any other upcoming, mortgage payment early to boost your year-end tax deduction amounts. Tax law generally prohibits write-offs for prepaid interest (there is an exception for loan points in some cases). Each year, you can deduct only the home mortgage interest for that year.


You also want to make sure you don't cut it too close in making the early payment. Get the check in the mail in plenty of time for it to arrive at your lender by year's end. If you pay online, be sure you make the electronic transaction in time to have it credited to this tax year's payment amount.

That way, the added interest will show up on the annual statement (usually a Form 1098 or an IRS-acceptable substitute) you'll get from your lender in late January, detailing your deductible mortgage activity.


Some tax professionals say you can simply make your extra mortgage payment late this month with a check dated Dec. 31 and count it toward your tax deductions.


However, if you actually get your payment to the bank by the last business day of the year or a day or two early, the extra interest will show up on the lender's official paperwork. And that means no curious tax examiner will question any difference between the amount you claim on your Schedule A and what your lender reported -- and copied to the IRS -- on the 1098 form.


If your year-end mortgage statement doesn't reflect the extra payment's interest, go ahead and deduct the correct amount on your tax return and attach a statement explaining why your number, not the lender's, is accurate.


If your mortgage holder pays your annual property tax bill from an escrow account, that also will be listed as a deductible home-related expense on your Form 1098. But if you, not your lender, pay your property tax bill, and it's due early next year, consider paying it in December as well. As with your mortgage interest, this payment -- and tax deduction -- will be shifted into this tax year.


A word -- actually, three words -- of warning about accelerating some tax payments: alternative minimum tax. This parallel tax system was devised in 1969 to guarantee that wealthy filers paid their fair share to the IRS. But nowadays, literally millions of middle-class filers are finding the AMT applies to them.


There are a couple of reasons so many taxpayers now potentially face the AMT. First, the parallel tax system isn't indexed for inflation. Without that annual adjustment, regular income increases have pushed many filers, particularly those in high-tax states such as New York and California, close to or into the earnings level where the AMT kicks in. So annually for the last few years, lawmakers have increased the income amount that is exempt from the AMT.


Second, under the AMT, some usually acceptable tax breaks aren't allowed. Mortgage interest on your main and second home is still AMT-deductible, but home equity loan interest could be disallowed. And real estate and personal property taxes aren't deductible under the AMT. So before you shift payment of those taxes into this year, make sure you won't face an AMT bill where the write-offs won't be of any tax use.


And remember: While an early payment will give you 13 mortgage interest amounts to deduct this year, it means that the next tax year you'll only have 11 -- or 12 if you pay a little early next December, too. So before you send off that check, make sure you really need the added tax deduction amount on this coming return.

Well, I just received my Form 1098 two days ago, so guess it is so!!

Never seen any institution that sends any statement until after the year has ended.  If your Dec payment is early in the month, then they must be assuming that you won't be making another until January. However, I believe your conclusion that "most" mortgage companies do this is false.

That is not so.  Who is your Mortgage Co?

Most mortgage companies send out the Form 1098 in early December, so making that extra payment in late December isn't going to count for the current year interest deduction.
