Mark to Market Accounting


Exactly what is Mark to Market?

According to the IRS: "A trader in securities or commodities may elect under section 475(f) to use the mark-to-market method to account for securities or commodities held in connection with a trading business. Under this method of accounting, any security or commodity held at the end of the tax year is treated as sold (and re-acquired) at its fair market value (FMV) on the last business day of that year."

What this basically means is that all open positions at year end are "marked to market" or priced to year end market prices to close out the position on paper.  Your open positions are still open, but now the the year end prices become the cost basis of these going into next tax year.

The Pros and Cons of Mark to Market

PROS:

If you are a active trader in securities or commodities, with a mark-to-market election in effect for the current tax year, then the following benefits can be yours:

  • Gains and losses from all securities or commodities held in connection with your trading business are treated as ordinary income and losses, instead of capital gains and losses.

    Normally, if your capital losses exceed your capital gains, the amount of the excess loss that can be claimed is limited by the IRS to $3,000 (or $1,500 if you are married filing separately). If your net capital loss is more than this limit, you can carry the loss forward to later years.  Now imagine a year where you lost $100,000!  How many years would it take to recoup that at a rate of $3,000 per year?

    With MTM status the limitation on capital losses do not apply. Therefore, if you had such a substantial loss, you may deduct this loss against all other types of taxable income without the normal $3000 loss limitation.
  • Mark to Market accounting provide a type of "tax loss insurance" as losses can be carried back two tax years. This is great news for active traders, who may have made a killing for one or more years only to have a substantial loss the following year.  If you have no other income to offset  this large loss, you may amend the previous two years tax returns and get a refund! No one like to lose money, but knowing you have some recourse to recoup some of those losses in case you do is quite comforting.
  • The wash sale rule does not apply to securities or commodities held in connection with your trading business when you have MTM trading status. This is also great news for active traders and may save quite a bit of heartache come tax time - see our Wash Sales: How they affect me trader tax topic.

CONS:

Mark to Market accounting is not without some downside. For example, if you have a large unrealized gain at year end in one or more of your open positions, you are forced to close those positions (on paper) using the year end prices which increases your current year taxable gain. This is true whether you are long or short.  Normally you do not realize gains until you actually close your positions, so be aware of this at year end if you have elected MTM.

How to elect Mark to Market status with the IRS

IRS Pub 550 states:

To make the mark-to-market election for 2006, you must file a statement by April 15 of the year you plan on using MTM accounting. This statement should be attached to either your individual income tax return or a request for an extension of time to file that return. The statement must include the following information.

  1. That you are making an election under section 475(f) of the Internal Revenue Code.
  2. The first tax year for which the election is effective.
  3. The trade or business for which you are making the election.

If you are not required to file an income tax return, you make the election by placing the above statement in your books and records no later than March 15. Attach a copy of the statement to your return.  Do not file form 3115 at this time as it may cause you to lose your MTM status.

After making the election to change to the mark-to-market method of accounting, you must change your method of accounting for securities when you file your taxes for the first  year using MTM accounting. You do this by filing Form 3115 - Application for Change in Accounting Method.

Form 3115 is also where you attach your section 481 adjustment - see How to report gains & losses Market to Market

Once you make the election, it will apply to the current tax year and all later tax years, unless you get permission from IRS to revoke it. The effect of making the election is described under Mark-to-market election made, earlier.

MTM Election Deadline:
Unless you are a new taxpayer, the election must be made by the due date (not including extensions) of the tax return for the year prior to the year for which the election becomes effective. In other words, if you have not made this election by April 15 of the current tax year, then you have to wait till next year to do so.

How to report gains & losses marked to market

If you made the mark-to-market election, you should report all gains and losses from trading as ordinary gains and losses in Part II of Form 4797, instead of as capital gains and losses on Schedule D. In that case, securities held at the end of the year in your business as a trader are marked to market by treating them as if they were sold (and re-acquired) for fair market value on the last business day of the year.

  • Do not mark to market any securities you held for investment.  Report sales from investments on Schedule D, not Form 4797.
  • Those who have elected the Mark to Market accounting method with the IRS report their gains and losses on the IRS FORM 4797 - Sales of Business Property - line 10.

The instructions for Form 4797 Line 10 states:
Report on line 10 all gains and losses from sales and dispositions of securities or commodities held in connection with your trading business, including gains and losses from marking to market securities and commodities held at the end of the tax year.

  • Attach to your tax return a statement, using the same format as line 10, showing the details of each transaction. - TradeLog MTM™ Form 4797 Attachment
  • On line 10 of Form 4797 enter “Trader - see attached” in column (a) and enter the totals from the form 4797 attachment in columns (d), (f), and (g).
  • Separately show and identify securities or commodities held and marked to market at the end of the year.
    - TradeLog MTM™ Securities Marked to Market
  • If this is the first year using mark to market accounting, attach the TradeLog MTM™ Section 481 Adjustment to your Form 3115 - see Form 3115 instructions.

Since all trades are priced to year end market prices and are therefore held one year or less, all of the MTM trades are by definition short term and are considered ordinary and are to be listed in Part II of this form.

There are seven columns in Part II as shown below:

(a) Description
of property
(b) Date acquired (c) Date sold (d) Gross
sales price
(e) Depreciation (f) Cost or other
basis
(g) Gain (or loss)
for entire year

Column (e) Depreciation is not used for the purposes of investments, so we will concern ourselves only with columns a-d, and f-g.

Once again, all of the same trade matching rules apply as described in our IRS schedule d tax topic under the heading: Matching and entering your trades on schedule d so having an automated method of doing so can save you many hours of grief.
