Nashua, NH Business License Guide

Nashua business changes: April 1–October 1, 2026

• Secondhand dealers: Nashua adopted O-26-012 as amended in August. The final action includes a 15-day holding period for secondhand dealers; pawnbrokers remain a separate category.
• Child care: New Hampshire changes effective July 1 strengthened by-right zoning treatment for qualifying home-based child care under RSA 674:16 and created commercial-zone protections for covered centers under RSA 674:81.
• Video display signs: Nashua adopted O-26-022 in September, creating a Video Display Signs Overlay District. Check the exact parcel before ordering this type of sign.

What does this mean for me?

Your path depends on the business. A home-based designer may focus on home-occupation and state-filing rules. A restaurant may need zoning, building, fire, health, tax, and employer steps. A food truck may need Environmental Health, City Clerk, Fire Marshal, and commissary approval.

An LLC, EIN, or state tax account is not local permission to operate. See Business License vs LLC vs DBA vs Seller’s Permit if those terms are unclear.

Nashua city requirements to check

Use the real city rule

Nashua lists specific licenses and permits rather than one general license for every business. The City Clerk handles activities such as vendors, taxicabs, chauffeurs, pawnbrokers, secondhand dealers, shows, events, raffles, and tag days.

Zoning and land use

Check zoning before signing a lease or buying equipment. Use the Land Use Code, Planning forms, and GIS tools, then confirm how the code applies to the exact use. Prior use, parking, storage, customers, deliveries, noise, outdoor activity, and construction can change the answer.

City limits and the exact address

Do not assume a Nashua mailing address settles the jurisdiction question. Before filing city forms, confirm that the parcel is actually inside Nashua and identify its zoning district. The city’s GIS tools are useful for this first check. If an address sits near a municipal boundary or the map result is unclear, give Planning the exact street address and parcel information before relying on a city rule.

Home-based businesses

Current § 190-47 separates minor and major home occupations. Minor uses are reviewed administratively for a certificate of use and occupancy and have tighter limits, including no nonresident employees, no more than 20% of the dwelling or 200 square feet, and infrequent business visits. Major home occupations require a special exception and follow different limits.

Use the current code plus the Planning forms page. Food, child care, salons, repair work, and other regulated activities may have separate rules. Effective July 1, 2026, state law also gives qualifying family/group family child care and covered commercial-zone child-care centers special zoning treatment that can limit local requirements.

For a general overview, see Home Occupation Permit Explained.

Building, fire, and occupancy

The Building Safety permit page provides building, land-use, trade, demolition, and sign forms. A new space, renovation, build-out, or change of use can require permits, inspections, and final approvals before opening.

Signs

Check the sign permit before ordering a sign. Nashua adopted O-26-022 in September 2026 for a Video Display Signs Overlay District; it is not a citywide permission for video signs.

City Clerk licenses

The City Clerk publishes current applications, fees, and renewal dates for listed licenses. In August 2026, Nashua adopted O-26-012 as amended for secondhand dealers, so businesses buying used property from the public should use the amended rule rather than an older copy of Chapter 220.

The City Clerk still lists a $50 pawnbroker/secondhand-dealer license valid until April 1. Because the 2026 ordinance changed the secondhand-dealer framework, a dealer should not treat the license fee page as the complete operating rule; check both the application and the latest adopted ordinance.

Food, mobile food, and temporary food

Nashua licenses and inspects food service locally. City materials say food sold, prepared, or distributed to the public generally needs local food-service approval and that residential/homestead kitchens are not recognized for public food sales, subject to limited exceptions.

Mobile units use the mobile-food path, including Environmental Health, a City Clerk hawkers/peddlers permit, fire review, and a commissary. Temporary events use the temporary-food page. Also see BLG’s food truck guide.

For temporary food service, Nashua currently lists a $50 application fee. Applications received less than two weeks before the event carry an additional $25 expedite fee, and applications received less than one week before the event are denied. The city also says food for temporary events must come from or be prepared in commercially licensed establishments rather than at home.

New Hampshire state steps for Nashua businesses

Entity or trade name

Use the Secretary of State and NH QuickStart for entity filings. The current LLC fee page lists $100 for a Certificate of Formation, $100 for the annual report, and a $50 late fee. A state electronic handling charge can also apply.

If a business uses a name other than the owner’s legal name, check the trade-name page. It lists $50 for registration and $50 for renewal. A trade name is not permission to operate at a Nashua address.

State taxes

New Hampshire has no general sales tax on goods. For taxable periods beginning on or after January 1, 2025, DRA lists a Business Enterprise Tax filing threshold above $298,000 of gross receipts or enterprise value tax base, and a Business Profits Tax filing threshold above $109,000 of gross business income. See DRA business taxes.

Future change to watch: New Hampshire law raises the Business Enterprise Tax filing threshold to more than $400,000 of gross business receipts or more than $400,000 of enterprise value tax base for taxable periods beginning January 1, 2027. The current $298,000 threshold remains the relevant published DRA threshold for taxable periods beginning in 2025 and 2026. See current RSA 77-E:5 for the scheduled 2027 change.

Covered meals, rooms, and motor-vehicle rentals use the Meals and Rooms (Rentals) Tax. DRA lists an 8.5% rate and requires covered operators to register before opening. Granite Tax Connect is the current portal.

Hiring employees

NH Employment Security requires an Employer Status Report within 30 days for employers providing employment in New Hampshire; the report was revised in June 2026. New-hire reporting is separate and generally due within 20 days. Also check payroll duties and the New Hampshire Department of Labor’s workers’ compensation rules.

Use the current NHES employer-registration page for the employer-status step and the agency’s employer forms/new-hire resources for reporting. These are separate from Secretary of State formation and DRA tax registration, so completing an LLC filing or Granite Tax Connect registration does not finish the employer checklist.

Professional and industry licenses

Regulated work needs the agency that actually licenses that activity. Businesses selling alcohol should use the New Hampshire Liquor Commission Division of Enforcement and Licensing. Retail tobacco sellers and samplers also use the Liquor Commission; tobacco manufacturers and wholesalers must also check the DRA tobacco-tax requirements. State-licensed professions and trades should use OPLC Professional Licensing. Child-care providers should use NH DHHS Child Care Licensing. Child-care zoning changed July 1, 2026, but state child-care licensing still applies.

Child-care zoning is now unusually important. Under RSA 674:16, VI, qualifying family and group family child care must be allowed by right on lots where residential use is permitted if state program requirements are met, and the statute bars different local requirements for that category. RSA 674:81 separately covers defined child-care centers on commercially zoned land. It still allows certain state fire, building, water, and sewage requirements, and local site-plan review can apply to a center with licensed capacity above 30 children.

Hillsborough County requirements

Most small businesses in Nashua should not expect Hillsborough County to be the main business license office. Nashua is the city layer, and New Hampshire is the state layer. County offices can still matter for property issues.

The Hillsborough County Registry of Deeds records legal documents that affect real estate, including deeds, mortgages, liens, attachments, plans, and other records. This can matter if you buy business property, finance real estate, or need to check property records.

Federal steps

Many businesses need an Employer Identification Number. The IRS EIN page says you can obtain an EIN directly from the IRS for free. An EIN may be needed for employees, corporations, partnerships, certain federal taxes, and other business situations.

Some regulated activities also need federal permits. The SBA licenses and permits page routes businesses to federal agencies by activity.

FinCEN finalized its current beneficial ownership information framework on August 11, 2026. The practical exemption for U.S.-created entities already existed under the 2025 interim rule; the 2026 final rule did not newly create that exemption. Under current FinCEN BOI guidance, U.S.-created companies are exempt, while certain foreign companies registered to do business in the United States can still have reporting duties.

Costs you can plan for

Use the current official fee page before filing; some costs vary by project.

What to do if the answer is unclear

If one office says it does not handle the issue, ask which office does. Send your exact activity, address, customer plan, and planned changes in writing. Ask direct questions such as: “Is this use allowed at this address?” “Which license or permit applies?” “Is occupancy approval required?” “Which current form should I use?”

If the issue involves a lease, major build-out, tax position, or another high-cost decision, professional advice may also be useful for your facts.
