Technology services companies occupy a gray area in the IRC 199A regulations that can be worth $37,000 or more per year in tax savings depending on how the business is classified. The SSTB “consulting” category under IRC 199A and Treas. Reg. 1.199A-5(b)(2)(vii) is defined as providing advice and counsel to clients, but the regulations carve out businesses where advice is incidental to the sale of goods or services. This creates a spectrum: pure strategy consulting firms are SSTBs, pure product/service delivery businesses aren’t, and most IT companies fall somewhere in between. The classification is based on the overall character of the business, not individual engagements, and a business that derives more than a de minimis amount of revenue from SSTB activities (10% for businesses with gross receipts under $25 million, 5% for those above $25 million) may be classified entirely as an SSTB unless the non-SSTB activities are separated into a distinct entity.

✓Key takeaway

IT services SSTB classification spectrum:

Business Type	SSTB Classification	QBI Deduction (High-Income Owner)
Pure IT strategy consulting	SSTB (consulting)	$0 (phased out above threshold)
Cybersecurity advisory / assessments	SSTB (consulting)	$0
Custom software development (for hire)	Likely non-SSTB (engineering/development, not consulting)	Full 20% deduction
Managed services (monitoring, maintenance, helpdesk)	Non-SSTB (service delivery, not advice)	Full 20% deduction
Cloud hosting / infrastructure management	Non-SSTB (IT services)	Full 20% deduction
SaaS product company	Non-SSTB (software product)	Full 20% deduction
IT staffing / staff augmentation	Non-SSTB (labor, not consulting)	Full 20% deduction
Mixed consulting + MSP	Depends on revenue mix	Separate into distinct entities if possible

R&D credit (IRC 41) for technology companies:

Qualifying Activity	Examples
Developing new software	Custom application development, SaaS product development
Improving existing software	Feature development, performance optimization, security hardening
Systems integration	Connecting disparate systems; developing APIs and middleware
Cloud architecture design	Designing scalable infrastructure; migration engineering
Cybersecurity tool development	Building security monitoring tools; developing threat detection
NOT qualifying	Routine maintenance, help desk, break-fix support, training

Credit Method	Calculation	Typical Benefit
Regular credit	20% of QREs above base amount	Higher if R&D is increasing
Alternative simplified credit (ASC)	14% of QREs above 50% of prior 3-year average	Simpler; most common for small businesses
Small business payroll offset	Up to $500,000 against payroll taxes (< $5M gross receipts)	Cash benefit even if no income tax liability

How should IT companies structure their taxes?

Hypothetical example

Round numbers. An MSP owner has $600,000 in net income from the business. The business provides managed IT services (70% of revenue), project-based IT work and implementations (20%), and strategic IT consulting (10%).

SSTB classification analysis:

Revenue Source	% of Revenue	SSTB?
Managed services (monitoring, patching, helpdesk)	70%	No
IT implementations (network builds, migrations)	20%	No
IT consulting (strategy, assessments)	10%	Yes

De minimis test: SSTB revenue (10%) equals the 10% de minimis threshold for businesses under $25M in gross receipts. If the consulting revenue is under 10%, the entire business may be treated as non-SSTB. If over 10%, the SSTB characterization could taint the entire business.

Strategy: Separate the consulting into a distinct entity:

Entity	Revenue	SSTB?	QBI
MSP LLC (managed services + implementations)	$2,700,000	No	$540,000 net income x 20% = $108,000 QBI deduction
Consulting LLC (IT strategy)	$300,000	Yes	$60,000 net income, but QBI = $0 (SSTB, above threshold)
Total QBI deduction			$108,000
Tax savings (37%)			$39,960

Without separation (all one entity, SSTB):

Item	Amount
Total QBI	$600,000
QBI deduction (SSTB, above threshold)	$0
Tax savings	$0

Separation saves $39,960 per year.

Requirements for the separation to be respected:

Separate legal entities (separate LLCs or S-Corps)
Separate books and records
Arm’s length transactions between entities
Genuine business purpose for the separation
Not merely a tax avoidance structure

R&D credit calculation for the MSP:

The MSP has 5 software developers who spend 60% of their time on qualifying R&D activities (developing automation tools, building custom integrations, improving the monitoring platform):

Item	Amount
Developer wages (5 x $120,000)	$600,000
Qualifying percentage	60%
Qualified Research Expenses (QREs)	$360,000
Supplies used in R&D	$20,000
Total QREs	$380,000
Prior 3-year average QREs	$300,000
ASC base (50% of prior average)	$150,000
QREs above base	$230,000
R&D credit (14% ASC)	$32,200
Tax reduction (dollar-for-dollar credit)	$32,200

If the MSP has gross receipts under $5,000,000 and was founded less than 5 years ago, up to $500,000 of the R&D credit can offset payroll taxes (FICA) instead of income tax.

S-Corp payroll tax optimization:

Item	Sole Proprietor	S-Corp
Net income	$600,000	$600,000
Reasonable salary	All income	$180,000
SE tax / employer FICA	$34,478	$13,770
Employee FICA	Included in SE	$13,770
Total payroll tax	$34,478	$27,540
Distribution (not subject to FICA)	$0	$420,000
Payroll tax savings		$6,938
Combined with QBI savings ($39,960) and R&D credit ($32,200)		$79,098/year

Key deductions for IT companies:

Expense	Section	Treatment
Software licenses and subscriptions	IRC 162	Currently deductible
Hardware (servers, networking equipment, workstations)	IRC 179 / 168(k)	Section 179 or 100% bonus depreciation
Cloud infrastructure (AWS, Azure, GCP)	IRC 162	Currently deductible
Employee training and certifications	IRC 162	Currently deductible
Professional liability (E&O) insurance	IRC 162	Currently deductible
Home office (remote workers)	IRC 280A	Simplified: $5/sq ft up to $1,500; or actual method
Vehicle (on-site client visits)	IRC 179 / 168	70 cents/mile or actual expenses
Conference and trade show attendance	IRC 162	Travel, registration, lodging deductible; meals 50%

Cybersecurity insurance and compliance costs:

Item	Deductible?	Notes
Cyber liability insurance	Yes	Ordinary and necessary business expense
SOC 2 audit costs	Yes	Directly related to business operations
Compliance certifications (ISO 27001, HIPAA)	Yes	Maintaining or improving skills and qualifications
Penetration testing	Yes	Security expense
Data breach response costs	Yes	Ordinary and necessary when incurred

Retirement plan strategies for IT business owners:

Plan	2025 Limit	Best For
Solo 401(k) with Roth option	$70,000 total ($23,500 employee + employer)	Owner-only or with spouse
Cash balance + 401(k) combo	$70,000 (401k) + up to $280,000 (cash balance) = $350,000	Very high earners; max deduction
SEP-IRA	$70,000 (25% of compensation)	Simple setup; no employee contributions

Which MSP and SaaS costs can be deducted right away?

Development work is the big one. For tax years beginning after 2024, domestic research or experimental expenditures are deductible in the year they’re paid or incurred under section 174A, which can cover U.S. development work on a SaaS product. Research done outside the U.S. is excluded, and whether a given project counts as research or experimental is its own question.

Off-the-shelf software you buy qualifies for Section 179. Otherwise it’s depreciated straight line over 36 months.
Certifications and training that maintain or improve skills in your current IT business are deductible. Training that qualifies someone for a new trade isn’t.
Professional liability insurance is deductible, and a policy prepaid for several years is deducted one year at a time.
