Accountants for Contractors: 7 Firms Compared for 2026

Accountants for contractors track job costs and project margins, run payroll and subcontractor 1099 reporting, handle sales tax where it applies, and plan federal, state, and city taxes around income that shifts from job to job. Say you're a Long Island remodeler with $400,000 in revenue, four open jobs, a growing W-2 crew, and six subs tracked in a spreadsheet. By December you can't tell which job made money, two W-9s are missing, and retainage is buried in receivables.

This comparison tests seven firms on job costing and work-in-progress (WIP) support, payroll and 1099 handling, sales tax, pricing transparency, and coverage for New York, New Jersey, and multi-state work. Thresholds and amounts adjust annually, so confirm figures for your tax year. Protecting trucks and tools is separate work, so review a contractor's guide to protecting machinery alongside the books.

1. Blue Sage Tax and Accounting Inc.

Blue Sage Tax and Accounting Inc. is an accounting firm in Bayside, Queens, serving small business owners, self-employed professionals, and individuals across the United States, with particular depth in New York and New Jersey filings. For a contractor, its focus is year-round tax planning, bookkeeping, and multi-state filings. It does not publish construction-specific WIP or job-costing services, so confirm whether those needs fit the scope before signing.

What stands out for trades owners

The firm runs a mid-year and fourth-quarter tax projection, sets quarterly estimates against it, and tells clients which actions remain available before year end. Clients work with the same accountant who prepares their return each year, with direct access to the firm's owner rather than rotating staff. Blue Sage also tracks 1099 contractor payments through the year and collects W-9s before January.

Services include business and individual tax preparation, S-corporation and partnership compliance, multi-state filings, bookkeeping, payroll and sales tax, and IRS and state notice response. For S-corporation owners, the IRS guidance on S-corporation compensation explains the reasonable-compensation requirement for shareholder-employees who provide services. The right amount depends on the circumstances, so discuss it as part of tax planning.

• Pricing: Monthly fees and one-time return fees are confirmed in a fixed written quote before individual tax preparation work begins.
• Separate quotes: Prior-period cleanup and catch-up bookkeeping are priced separately from monthly bookkeeping. Complex IRS examinations, entity formation, and one-off consulting outside the plan scope are also quoted separately.
• Business coverage: The firm serves contractors and businesses across industries, including transportation, restaurants, medical practices, real estate, retail, and technology. Its accounting and tax services include bookkeeping, tax planning, multi-state filings, and notice response.

Practical rule: Monthly bookkeeping is the minimum to consider if you make estimated tax payments, borrow, or plan around profit. Records reconciled as transactions happen provide a more useful basis for projections than year-end cleanup alone.

The fit is strongest when tax projections, consistent books, and multi-state compliance are the main needs. Before signing, ask whether the engagement covers your specific job-costing, WIP, and retainage requirements. Blue Sage does not provide audits, reviews, compilations, business valuations, M&A advisory, forensic accounting, or legal services.

2. Castaldo CPA and Associates

Castaldo CPA and Associates is a Long Island firm built around contractors and trades businesses, not general small-business accounting with a construction page added later. Its published materials address WIP, retainage, change orders, and contractor cash flow, which is the right vocabulary if your spreadsheet can't answer job-level questions.

The service mix covers bookkeeping, tax planning and compliance, job costing and project-cost tracking, QuickBooks support, cash-flow management, and part-time controller services. That controller layer matters when you're big enough to need committed-cost reviews but not big enough to hire in-house. A free consultation is advertised.

Classification is where local crews get tripped up. Before you assume a sub is fine because he invoices you, work through the W-2 contractor versus 1099 contractor distinction and confirm how the firm reviews it. A 1099 on file doesn't settle control, tools, or exclusivity questions.

• Best fit: Long Island general and specialty contractors who want job costing plus tax planning under one roof.
• Pricing transparency: Ongoing fees aren't published, so ask what's included monthly versus billed as controller time.
• Geography trade-off: The stated local focus may suit you less if you want an exclusively nationwide virtual firm.

Confirm whether QuickBooks cleanup, cost-code setup, and WIP schedules are in the base fee or priced as a separate onboarding project.

3. d.f. o'brien and co.

If you run crews in both New York and New Jersey, d.f. o'brien and co. is positioned directly at that problem. The firm serves general contractors, subcontractors, trades, engineers, and architects, and highlights New York and New Jersey contractor tax strategy, including PTET guidance. It states more than 40 years of construction-focused experience.

Monthly construction bookkeeping, job costing, and WIP schedules sit alongside bonding-ready financial statements, payroll and 1099 support, multi-state tax services, and IRS support. That combination suits a contractor whose lender or surety asks questions a basic profit and loss statement can't answer.

New Jersey classification deserves its own check. Under New Jersey's Department of Labor ABC test guidance, a worker is presumed to be an employee for unemployment compensation unless the business proves all three conditions on control, place and course of business, and an independently established trade. Issuing a federal Form 1099 doesn't satisfy that state test on its own.

• Regional strength: NY/NJ tax planning is central, not an add-on.
• Reporting depth: WIP and bonding-ready statements are named services, not implied.
• What to verify: Fees aren't published. Testimonials on the site are firm-published, not independent review data, so ask for scope and deliverables in writing.

If you only need tax filing and light bookkeeping, confirm you're not buying a heavier construction reporting package than your jobs require.

4. VOS CPAs

VOS CPAs describes construction as its core industry and lists a service area covering New York City's five boroughs, Long Island, Westchester, and Northern New Jersey. Its services include job costing, work-in-progress reporting, project profitability, bonding and cash-flow support, payroll, and construction tax strategy.

That focus may suit established contractors whose sureties review WIP schedules and whose managers need to track job performance. VOS's materials describe those services, but do not publish pricing.

Where to press before signing

Ask for a written scope and fee, and clarify which services the quote covers. VOS also offers attestation services, which serve a different purpose from bookkeeping and tax preparation and can affect the engagement's cost.

A bonding-ready statement depends on accurate job costs. Ask who reviews field time and subcontractor invoices before they flow into WIP reports, and who prepares the year-end statements.

Confirm current offerings, staffing, and turnaround directly with the firm. VOS may fit a construction company with detailed reporting and bonding needs; a solo tradesperson should confirm whether the available scope also covers routine bookkeeping, payroll, and quarterly estimates.

5. Independent Contractor Tax Advisors

Independent Contractor Tax Advisors serves independent contractors, consultants, freelancers, and other self-employed clients nationwide. Its focus is the solo 1099 operator, rather than a bonded general contractor coordinating retainage and work-in-progress across multiple jobs.

Services include bookkeeping, payroll, quarterly and annual tax preparation, quarterly tax checkups, and audit support, with fixed monthly fees. The firm does not publish specific plan prices, so “fixed” describes the billing structure, not a figure to budget from. Ask what the fee covers, and whether job costing, retainage tracking, or multi-state filings are included if your business has crews or projects in more than one state.

The IRS FAQ on Form 1099-NEC and independent contractors says most self-employed individuals must pay self-employment tax when net earnings reach $400 or more. Late or insufficient estimated tax payments can also result in an underpayment penalty. Confirm the applicable threshold for your tax year. For practical guidance on contractor tax obligations, see taxes for a 1099 contractor.

• Best fit: Solo contractors and consultants who want regular tax checkups rather than contact only at filing time.
• Limit to test: As your operation adds crews and larger contracts, confirm whether the firm can handle WIP, retainage, job costing, and multi-state crews.
• Reputation check: The firm's reputation is mostly reflected in its own marketing. Ask for references from contractors in your trade before signing.

6. Next Level CPA

Next Level CPA offers four contractor accounting tiers, from owner-operators to larger bonded or multi-state businesses. Depending on the package, services include business and personal tax returns, job costing, bookkeeping, retainage tracking, WIP schedules, cash-flow forecasting, and surety reporting. Certified payroll and AIA pay-application preparation are available as add-ons.

Published starting prices range from $697 to $4,497 or more per month, plus onboarding. Final pricing depends on the books' condition, job volume, and payroll. Rebuild work is available for disorganized or overdue records, but confirm whether cleanup is included or priced separately before signing.

Accounting software is common in construction, but it only helps when cost codes are consistent and transactions are reconciled regularly. For contractors, that means checking whether job costs, retainage, and WIP schedules reflect the way work and payments move through the business.

• Comparison advantage: Published package descriptions and starting prices make it possible to shortlist options before a sales call.
• Cost to confirm: Ask what onboarding includes and whether catch-up or cleanup work carries a separate charge.
• Coverage to confirm: Check geographic availability and whether the firm handles filings in New York, New Jersey, or other states where you work.

A solo contractor may not need the reporting features aimed at bonded businesses. Choose a tier based on the job-costing, payroll, and surety requirements you have.

7. Acharya CPA and Co.

A late progress payment can leave a profitable contractor short on payroll cash. Acharya CPA and Co. offers virtual accounting to construction and skilled-trades businesses nationwide, including general and specialty contractors, remodelers, HVAC, plumbing, and electrical businesses.

Its services include monthly job-cost reporting, a 13-week cash forecast, equipment and depreciation planning, payroll and 1099 oversight, and lender-ready or bonding-ready financial statements. Ask how often the forecast and job-cost reports are updated, and whether the firm tracks work in progress, retainage, and job costs in the format your lender or surety needs. Confirm, too, whether 1099 collection happens before January and whether multi-state crew filings fit your jobs.

Cloud accounting requires field data, receipts, and time records to reach the books regularly. The 2025 Associated General Contractors of America and Sage Construction Hiring and Business Outlook Report, based on 1,109 firms, found that 48% reported using cloud-hosted accounting technology. A virtual accounting arrangement depends on a workable routine for sharing records.

• Pricing: The firm offers tiered paid plans. Confirm current pricing and consultation details directly with the firm.
• Trade-off: A tiered accounting package may be more than a side business needs if it only wants tax filing.
• Jurisdiction check: The practice is based in Washington State. Confirm coverage for New York State, New York City, New Jersey, or any other states where you work.

How the 7 accountants for contractors compare on pricing, geography, and fit

Matching the Accountant to Your Trade, Your Books, and Your States

Start with what you are today. A solo electrician with no employees needs clean books, separation of personal and business spending, and estimates that flex with seasonal work. A growing GC with W-2 crews and subs needs job costing, payroll discipline, and W-9 collection before January. A bonded, multi-state contractor needs WIP, retainage tracking, and statements a surety will accept.

Then test the quote, not the homepage. Ask each firm which of these are included in the monthly price and which are separate: cleanup of prior periods, cost-code setup, payroll runs, sales-tax filings, 1099 issuance, projections, and notice response. Several firms here offer a free consultation and a written scope before work starts. Cleanup of prior-period books is commonly quoted separately, and that's reasonable, provided the number is in writing before anyone touches your file.

State coverage is the third filter, and it's not interchangeable. Federal rules, New York State and City rules, and New Jersey rules treat classification, pass-through entity tax, and sales tax differently. Confirm directly that the firm files in every state where your crews work, not just where your office sits. Owners comparing professional risk can also explore E&O coverage for accountants to understand what questions to ask any firm about its own coverage.

For owner-operators and growing trades firms whose priority is year-round projections, monthly bookkeeping, payroll and sales tax, and multi-state filings, our process is a free consultation call, a fixed quote in writing, then filing with a projection before year end. Book your free consultation call today.
