Title 26 › Subtitle Subtitle F— - Procedure and Administration › Chapter CHAPTER 63— - ASSESSMENT › Subchapter Subchapter C— - Treatment of Partnerships › Part PART II— - PARTNERSHIP ADJUSTMENTS › § 6225
When the IRS adjusts a partnership’s tax items for a past year, the partnership must either pay a calculated tax amount in the adjustment year if those changes create an “imputed underpayment,” or else take the adjustments into account in the adjustment year if no imputed underpayment results. The IRS figures an imputed underpayment by adding up (and offsetting) the partnership’s adjustments for the reviewed year and then applying the highest tax rate that applied in that reviewed year under sections 1 or 11. If an adjustment just moves an item from one partner to another and that move would lower the imputed underpayment, the IRS ignores the lowering part. The IRS also must make rules that let partners instead file returns or pay the tax and accept changes to their tax attributes so the partner-level tax can be fixed; those partner-level changes are binding. The rules must also let the partnership exclude amounts that go to tax-exempt partners, allow lower tax rates for amounts allocable to C corporations (and for individuals’ capital gains or qualified dividends), cover special passive-loss rules for publicly traded partnerships, and allow the IRS to add other reasonable procedures. Any filings or submissions under these rules must be sent to the IRS within 270 days after the IRS mails the notice of proposed partnership adjustment, unless that deadline is extended by the IRS, and any change to the imputed underpayment needs IRS approval. Reviewed year: the partnership tax year the adjusted item relates to. Adjustment year: the partnership tax year when the adjustment becomes final by court decision, when an administrative adjustment request is made, or when the IRS mails notice of final partnership adjustment.
