830 CMR, § 62C.26.2
In the case of most Massachusetts tax types, a taxpayer is required by M.G.L. c. 62C to file a return, on or before a required due date, upon which the amount of tax due is calculated and declared by the taxpayer. The tax declared on the return filed by the taxpayer is a self-assessment of tax by the taxpayer. In general, a self-assessment is accepted as the tax due from the taxpayer for the tax period indicated on the return unless the self-assessed amount is later adjusted, either by the Commissioner or by the taxpayer. In most cases, adjustments by the Commissioner take the form of a correction of a mathematical or other error evident on the face of the return, or follow from the statutory process associated with a deficiency assessment. In contrast, 830 CMR 62C.26.2 discusses taxpayer adjustments to a previously filed return through the filing of an amended return, either to increase or to decrease the amount of previously self-assessed tax or otherwise to adjust items shown on previous returns.
The Commissioner has modified return processing procedures with regards to amended returns to improve processing time and efficiency while maintaining the right of a taxpayer to contest assessments of tax, including self-assessments. Historically, amended returns that increased the tax reported to be due were processed separately from amended returns that reduced the tax reported to be due. The latter were treated as "abatements" and were manually evaluated. Under the revised procedures provided in 830 CMR 62C.26.2, amended returns generally are now processed in the same manner as original returns, without regard to whether the amended return increases or decreases a prior self-assessment. Amended returns are subject to review and/or adjustment by the Commissioner in the same manner as original returns. With some exceptions, which are not itemized here, the abatement process is reserved for situations where the taxpayer disputes a deficiency assessment or an assessment of penalties by the commissioner. See830 CMR 62C.37.1.
Abatement, an application by a taxpayer pursuant to M.G.L. c. 62C, § 37 that seeks to reduce a previous assessment of tax and/or penalties.
Amended Return, a correction or adjustment made by a taxpayer to a previously filed return.
Assessment, any determination of tax due under M.G.L. c. 62C, including the self-assessment of tax by a taxpayer on a return or a deficiency assessment by the Commissioner.
Commissioner, the Commissioner of Revenue or the Commissioner's designee duly authorized to perform the duties of the Commissioner.
Deficiency Assessment, the assessment of tax by the Commissioner pursuant to M.G.L. c. 62C, including, generally, assessments under M.G.L. c. 62C, § 26, and jeopardy assessments under M.G.L. c. 62C, § 29.
Original Return, the first complete return filed by a taxpayer for a particular tax type and taxable period.
Return, a taxpayer's signed declaration of the tax due, if any, properly completed and filed by the taxpayer in the manner prescribed by the Commissioner.
Self-assessment, the declaration of a tax due by a taxpayer on a return pursuant to M.G.L. c. 62C, § 26(a), or other applicable law.
Taxpayer, any person or entity required to file a return pursuant to M.G.L. c. 62C.
In the event that the Commissioner fails to take action with regard to a properly filed amended return that reduces a self-assessment before the expiration of the statute of limitations under M.G.L. c. 62C, §§ 30, 30A and/or 37, such amended return will be deemed by the Commissioner to be an abatement as of the date of filing the amended return. For purposes of 830 CMR 62C.26.2(5), to "take action" with regard to an amended return means when the taxpayer's self-assessment is reduced on the Commissioner's books and records and/or a refund is issued to the taxpayer; the Commissioner issues a Notice of Intent to Assess, Notice of Change, Notice of Assessment or any other notice related to the reduction sought required under M.G.L. c. 62C; the Commissioner issues a letter informing the taxpayer that its amended return has been deemed an abatement application; the Commissioner issues a notice of abatement determination, or the Commissioner issues any other notice indicating resolution of the amended return.
As stated in 830 CMR 62C.37.1(5)(c), the filing of an amended return shall act as a waiver of the right to treat the Commissioner's failure to act on an amended return deemed to be an abatement application prior to six months from the date of filing as a denial of the application pursuant to M.G.L. c. 58A, § 6. This waiver may be withdrawn at any time in writing by the applicant, in which event the application, unless previously acted upon by the Commissioner, shall be deemed to be denied at the expiration of the six months or on the date of withdrawal, whichever is later.
Where the Commissioner deems an amended return to be an abatement, the process under M.G.L. c. 62C, § 37 and 830 CMR 62C.37.1 shall apply.
