WHO MUST FILE
All business organizations, including single member Limited Liability Companies (SMLLC), taxed as a corporation federally must file a Form NH-1120 return provided 
they  have conducted business activity in New Hampshire and their gross business income from everywhere is in excess of $103,000 (for taxable periods beginning 
January 1, 2023). 
"Gross business income" means all income for federal income tax purposes from whatever source derived in the conduct of business activity, including but not limited 
to  gross proceeds from sales, compensation for rendering services, gross proceeds realized from trading in stocks, bonds, or other evidences of indebtedness, gross 
proceeds realized from sale of assets used in trade or business, interest, discount, gross rents, royalties, fees, commissions, dividends, without any deduction on account  
of the cost of property sold, the cost of materials used, labor costs, interest, discount, delivery costs, taxes, or any other expense paid or accrued and without any  
deduction on account of losses.   

CONFIDENTIAL INFORMATION  
Tax information disclosed to the New Hampshire Department of Revenue Administration is held in strict confidence by law. The information may be disclosed to the  
United States Internal Revenue Service, agencies responsible for the administration of taxes in other states in accordance with compacts for the exchange of 
information,  and as otherwise authorized by RSA 21-J:14.   

TAXPAYER IDENTIFICATION
The Commissioner of the Department of Revenue is authorized pursuant to RSA21:J27-a to require submission of an SSN, FEIN, or any other identifying number used in  
filing or preparing federal tax documents.  If you do not have any such identifying number, or share one with another taxpayer, then, under N.H. Code of Admin. Rules,  
Rev 2903.01, you must obtain a Department Identification Number (DIN).  If you have a DIN, use it on all New Hampshire filings.  To ensure that your filings and 
payments  are applied to the correct account, the sequence of names and taxpayer ID numbers on all filings must be consistent. The failure to provide a taxpayer 
identification  number may result in the rejection of filed documents.  Failure to timely file documents complete with a consistent taxpayer identification number may 
result in the  imposition of penalties and interest, the disallowance of claimed exemptions, exclusions, credits, deductions, or an adjustment that may result in increased 
tax liability.

NAME AND TAXPAYER IDENTIFICATION NUMBER
Enter the taxpayer's name and taxpayer identification number in the spaces provided. 
Enter the beginning and ending dates of the taxable period.   
These instructions apply to a separate entity corporate filer.     
New Hampshire requires business organizations that are conducting a unitary business inside and outside New Hampshire to file a combined Business Profits Tax (BPT)  
return (a member of the unitary group must be subject to tax in another jurisdiction). Combined groups are required to file Form NH-1120-WE . You may obtain the 
form  from our website at www.revenue.nh.gov or by calling the Forms Line at (603)230-5001.   
IF THIS BUSINESS FILES A FORM 1120S U. S. INCOME TAX RETURN FOR AN S-CORPORATION  WITH THE INTERNAL REVENUE SERVICE, A NH DP-120  
“COMPUTATION OF S-CORPORATION GROSS BUSINESS PROFITS” MUST BE COMPLETED BEFORE THIS FORM IS COMPLETED.   

LINE 1 - FEDERAL TAXABLE INCOME/(LOSS)
The Business Profits Tax is a 7.5% (for taxable periods ending on or after December 31, 2023)tax assessed on taxable business profits. 
Round every entry to the nearest whole dollar (if 49 cents or less round down, if 50 cents or more round up). 
REPORT NEGATIVE AMOUNTS USING A MINUS SIGN.  
LINE 1
Enter the amount from Line 28 of the Federal Form 1120 or complete a New Hampshire Form DP-120 (if applicable) and enter the amount from Line 2 of the Form  
DP-120 (Attach the completed Form DP-120 to the tax return).   

LINES 2(a)-2(g), 3, 4, AND 5 - INCREASE OR DECREASE TO GROSS BUSINESS PROFITS TO RECONCILE WITH IRC
Lines 2(a) through 2(g) are adjustments necessary to increase or decrease gross business profits to reflect the applicable Internal Revenue Code (IRC) applicable 
pursuant  to RSA 77-A:1, XX and RSA 77-A:3-b. If a taxpayer seeks to report a necessary adjustment that has not been specifically addressed the taxpayer shall enter the 
item on  either Line 2(d) or 2(f) and complete the attachedSchedule IV.
Pursuant to RSA 77-A:1, XX, New Hampshire has adopted the IRC as of a particular date for each taxable period. As a result, taxpayers must identify any changes to the 
IRC occurring subsequent to the version adopted by New Hampshire, and account for those changes on their return. Taxpayers must also make additional adjustments 
as directed by RSA 77-A:3-b.

                                         TAXABLE PERIOD - BEGINNING                          IRC VERSION IN EFFECT
                                        01/01/2020 - Current                                  December 31, 2018
                                        01/01/2018 - 12/31/2019                               December 31, 2016
                                        01/01/2017 - 12/31/2017                               December 31, 2015
                                        01/02/2000 - 12/31/2016                               December 31, 2000
                                                        For prior taxable periods reference RSA 77-A:1, XX  

The adjustments on lines 2(a) through 2(g) reflect the adjustments that are necessary to account for the version of the IRC adopted by New Hampshire. If a taxpayer 
seeks to report a necessary adjustment that has not been specifically addressed, the taxpayer shall enter the item on either line 2(c) or 2(e).
The statutory requirement to follow the IRC applicable pursuant to RSA 77-A:1, XX and RSA 77-A:3-b has significant impact on the tax basis of assets used in businesses 
operating within and without New Hampshire. A separate accounting of the New Hampshire tax basis must be maintained for depreciation purposes and for 
determination of the gain or loss in the event of the sale of business assets.
LINE 2(a)
Add the amount of IRC §179 expense taken on the federal return in excess of the amount permitted pursuant to RSA 77-A:3-b. For property placed in service on or 
after January 1, 2017, the maximum IRC § 179 deduction is $100,000. For property placed in service on or after January 1, 2018, the maximum IRC § 179 deduction
is $500,000.
LINE 2(b)
Add the amount of bonus depreciation taken on the federal return for assets placed in service this period. Bonus depreciation, allowed federally under IRC §168(k), is 
not allowed for New Hampshire BPT purposes.
LINE 2(c)
Add any other deductions or exclusions taken on the federal return that need to be eliminated or adjusted due to revisions to the IRC occurring subsequent to the 
applicable version in the table above. Include foreign dividends, when actually distributed, that consist of amounts previously taxed federally as GILTI under IRC § 
951A, or of amounts previously taxed federally as deemed one-time repatriation under the Tax Cuts and Jobs Act of 2017, but not previously subject to Business Profits 
Tax. Complete and attach Form Schedule IV.
LINE 2(d)
Deduct the regular depreciation related to IRC §179 and bonus depreciation not allowed for this tax year or for prior tax years. Because there may be a basis difference 
due to the federal and state treatment of IRC §179 expense, and bonus depreciation, the regular depreciation allowed under IRC §167 and IRC §168 may be different 
than that deducted on the federal return. Recalculate your allowable depreciation and deduct the difference on this line.

LINE 2(e)
Deduct any other items included on the federal return that are required to be eliminated or adjusted due to revisions to the IRC occurring subsequent to the
version adopted by New Hampshire pursuant to RSA 77-A:1, XX and RSA 77-A:3-b. Also include the deduction allowed for global intangible low-taxed income under
RSA 77-A:4, XIX. Complete and attach Form Schedule IV.
LINE 2(f)
Increase or decrease the net gain or loss on the sale of assets used in the business which have a different state adjusted basis from the tax adjusted basis
reported on the federal return. Because there may be a basis difference to the federal and state treatment of IRC §179 expense, and bonus depreciation, the regular
depreciation allowed pursuant to IRC §167 and IRC §168 may be different then that deducted on the federal return. This may create a different adjusted basis to assets
used in the business which have not been completely depreciated and thus a different gain or loss for state reporting than that reported on the federal return on the
sale of business assets. Recalculate the gain or loss and enter the difference on this line. Adjustments required to account for the net gain or loss attributable to an
increase or step-up in the basis of assets pursuant to RSA 77-A:4, XIV shall be reported in Section 6(h).
LINE 2(g)
The sum of Lines 2(a) through 2(c), minus Lines 2(d) and 2(e), adjusted by Line 2(f); if negative result, use a minus sign.
LINE 3
Subtotal Line 1 adjusted by Line 2(g); if negative result, use a minus sign.
LINE 4
Separate entity adjustments to income or expense, attach schedule. Enter the amounts which arise from the necessity of adjusting Gross Business Profits to
accommodate the New Hampshire requirement of separate entity treatment for business organizations. Do not eliminate investment income on this line, as New
Hampshire requires that all business income be included. New Hampshire does not have a non-business income statute.
LINE 5
Gross Business Profits, combine Line 3 and Line 4.

LINES 6(a)-6(k), 7, 8, 9, 10, 11, 12, 13, AND 14 - ADDITIONS AND DEDUCTIONS (RSA 77-A:4)
LINE 6(a) 
Deduct interest income earned resulting from investments in direct United States obligations, net of expenses, on this line.
Federal obligations are exempt from tax by states or their political subdivisions when obligations are issued to secure credit to carry on the necessary functions of
government. Exempt U.S. Government interest claimed as a deduction must be reduced by the following expenses if the expenses were claimed as deductions in
arriving at your federal taxable income:
• interest on money borrowed to purchase or carry the bonds or securities; and 
• ordinary and necessary expenses paid or incurred in connection with producing exempt income.
These expenses may also be added back on Line 6(e). Do not add back twice.
LINE 6(b)
Add net income taxes, franchise taxes measured by net income, or capital stock tax taken as a deduction on the federal return for any state or political subdivision or 
foreign taxes based on or measured by net income.
The Business Enterprise Tax (BET) is not based on or measured by net income and is not added back. Business Profits Tax (BPT) is based on net income and must be
added back, if a deduction for BPT has been taken on your Federal tax return.
LINE 6(c) 
Add federal non-recognized IRC §337 gain. New Hampshire recognizes the gain on the distribution of property from a subsidiary to its parent in complete liquidation 
of the subsidiary. The gain of the liquidating corporation is determined using the New Hampshire basis of the assets distributed.
LINE 6(d) 
Deduct the wage adjustment required by IRC §280C. Deduct the wages or salaries paid or incurred for the taxable year which is equal to the sum of the credit
determined for the taxable year under IRC §45A(a), §51(a), §1396(a), §1400P(b), and §1400R.
LINE 6(e) 
Add expenses related to constitutionally exempt income. Expenses that are incurred to produce income that is constitutionally exempt from taxation in New 
Hampshire must be added back to gross business profits. These expenses include such items as interest expense and other expenses incurred to earn interest from
investments in direct U.S. obligations (refer to Rev 303.04 for further information). This add back also includes expenses related to the production of non-unitary 
income not included on this return.
LINE 6(f) 
Deduct Foreign dividend gross-up (IRC §78). IRC §78 provides that dividends received from foreign affiliates are “grossed-up” to include income taxes paid on the 
dividends to foreign countries. The taxpayer can then apply the grossed-up amount in computing its foreign tax credit for federal purposes. The amount of gross- up is 
a separately stated item on the Federal Form 1120, Schedule C. Qualified dividends do not include IRC §78 amounts. Deduct the gross-up on this line.
LINE 6(g) 
A deduction is allowed for the contribution of scientific equipment or apparatus to an educational organization or institute of higher education equal to the sum of the 
taxpayer's basis in the contributed property plus 50 percent of the unrealized appreciation, or twice the basis of the property, whichever is less.
