Could a California savings and loan association amend an earlier return to increase its bad-debt reserve deduction after the filing deadline?

Plain-English summary

California Legal Ruling 417 allowed a savings and loan association to amend an earlier return to increase its bad-debt deduction only up to the reserve addition already recorded on its books for that year.

The association could correct a return that claimed less than the booked reserve, as long as the amendment was timely and the deduction was otherwise allowable.

It could not use an amended return to retroactively increase the underlying book reserve. FTB treated the year-end books as the best evidence of the association's contemporaneous reserve determination and would not permit a later enlargement based on hindsight.

The two decisions

Requested deduction exceeded the book reserve

FTB said no. A deduction larger than the reserve addition recorded on the books would require changing the association's original year-end determination.

The ruling reasoned that allowing later changes would undermine the reserve method by shifting bad-debt deductions into a year other than the year reflected by the contemporaneous loss estimate.

Requested deduction did not exceed the book reserve

FTB said yes. An association could amend the return to claim an amount equal to or below the already booked reserve because that did not change the original reserve determination.

The amendment still had to be filed within the statute of limitations and comply with the Bank and Corporation Tax Law and applicable regulations.

Why the books controlled

Former Regulation 24348(b) allowed a savings and loan association to deduct a reasonable addition to its reserve for bad debts.

The ruling said the reserve was meant to account for loans foreseeably not repaid. The association was given the initial privilege of deciding the yearly addition near year-end based on facts then known.

The amount entered on the books generally was the best evidence of that decision and the association's actual loss experience. A fairly made year-end decision could not later be enlarged or reduced merely to change the tax result.

Limits on the ruling

FTB expressly said the opinion did not address:

• a year for which additional assessments had been proposed; or
• an open year in which FTB revised the association's loan-loss ratio.

Those circumstances could require a different analysis.

What this means for you

Savings and loan associations

Under the historical reserve method, the tax return could be corrected to match the books, but the books could not be rewritten after the fact to create a larger deduction.

Financial-institution tax departments

Preserve the contemporaneous reserve workpapers, board or management approvals, and general-ledger entries. The ruling treated those records as evidence of the year-end loss estimate.

Accountants and tax professionals

Check the booked reserve, the amount claimed on the original return, the limitations period, any proposed assessment, and whether FTB changed the loss ratio before recommending an amended claim.

Common questions

Q: Could an association claim a deduction omitted from the original return?

A: Yes, up to the reserve already recorded on its books, if the amended claim was timely and otherwise allowable.

Q: Could it increase both the books and the deduction later?

A: No. The ruling prohibited a retroactive increase beyond the contemporaneous book reserve.

Q: Why did FTB rely on the book amount?

A: It was the best evidence of the association's year-end determination based on the facts and loss experience then available.

Q: Did the ruling apply when FTB proposed an assessment?

A: No. It expressly excluded years with proposed additional assessments.

Q: Did it apply after FTB revised the loan-loss ratio?

A: No. The opinion excluded open years involving an FTB revision of that ratio.

Retroactive Changes to Bad-Debt reserve for Savings and Loan Associations

Facts

Advice has been requested in two cases where savings and loan associations have attempted to modify in a later year the bad-debt reserve claimed on a return for an earlier year:

The first case involves an association that seeks to increase the bad-debt deduction to an amount greater than the addition it made to the reserve for bad debts on the savings and loan's books for that year;

The second case involves an association that seeks to increase the bad-debt deduction to an amount equal to or less than the addition it made to the reserve for bad debts on the savings and loan's books for that year.

In neither case have there been any assessments of additional tax for the year involved or a change of the taxpayer’s bad debt loss ratio.

Questions

May a savings and loan association retroactively increase the amount of its bad-debt deduction, after the date prescribed for filing the return has expired, to an amount greater than the addition it made to the reserve for bad debts on the savings and loan's books for that year?

May a savings and loan association retroactively increase the amount of its bad-debt deduction, after the date prescribed for filing the return has expired, to an amount equal to or less than the addition it made to the reserve for bad debts on the savings and loan's books for that year?

Decisions

No.

Yes.

Discussion

Regulation 24348(b) allows a savings and loan association to deduct each year a reasonable addition to its reserve for bad debts. The purpose of the reserve is to allow the taxpayer to exclude from gross income loans which foreseeably will not be repaid. The taxpayer is initially given the privilege to determine the amount of the yearly addition. That determination should be made at or near the close of the income year, based upon facts existing at that time. The best evidence of the taxpayer’s determination generally will be the amount shown on its books, reflecting actual loss experience. A determination fairly made at the close of the year may not be enlarged or diminished at a later date, for then the reserve would cease to be a true reserve and the taxpayer, contrary to the spirit of the statute, would be permitted to deduct worthless debts in a year other than that in which their worthlessness would be realized. Therefore, when considering retroactive increases to additions to bad-debt reserves on returns, the amount of increase allowed is limited to the amount of addition already entered on the savings and loan association's books, provided the increase is otherwise allowable by the Bank and Corporation Tax Law and the regulations promulgated thereunder and within the period of the statute of limitations.

Question #1 requires an adjustment to the self-determined addition entered on the association's books. Therefore, an increase on the return is not allowable as it would not reflect the experiential loss on the association's books. Farmville Oil & Fertilizer Co. v. Commissioner, 78 Fed.2d 83, 85 (4th Cir. 1935); Rogan v. Commercial Discount Co., Fed.2d 585 (9th Cir. 1945), cert, den. 326 U.S. 764 (1945).

Question #2 requires no adjustment to the association's books. As long as there is no retroactive adjustment to the association's addition for bad-debt reserve on its books the bad-debt deduction claimed on the return may be amended provided it is within the period of statute of limitations for such amendments and otherwise allowable by our laws and regulations. Appeal of Culver Federal Savings and Loan Association, Cal. St. Bd. of Equal., February 14, 1966, CCH 203-256, P-H 13,383.

This opinion is not meant to apply for a year in which additional assessments have been proposed or for any year not barred by the statute of limitations where the association's loan loss ratio is revised by this department.

Given a hypothetical of:

Example 1977 1978

Bad-Debt Deduction Claimed on Books $76,000 $10,000

Bad-Debt Deduction Claimed Original State Return -0- -0-

Bad-Debt Deduction Claimed Amended State Return(within the period of statute of limitations) 76,000 33,000

In applying these legal rules to this hypothetical situation, the retroactive deduction of the previously determined addition to the bad-debt reserve made in 1977 for $10,000 and in 1978 for $76,000 may be allowed, as long as this is done within the statute of limitations and otherwise allowable by the Bank and Corporation Tax Law and the regulations promulgated thereunder (particularly Reg. 24348(b) ). However, the subsequently desired reasonable reserve addition of an additional $23,000 for 1977 cannot be allowed as this would constitute a retroactive increase to the determination on the books, which is not allowed.
