Accounting Firm Schema Markup: AccountingService, Person, and Author Markup in 2026

Q: What about firms with multiple offices?

Each office can have its own AccountingService block with location-specific address and geo coordinates. Link them as branches of a parent organization if applicable.

When ChatGPT answers “best CPA for short-term rental investors,” it needs to verify that the firms it considers are actually accounting firms with credentialed CPAs. Schema markup is the primary mechanism. Firms with structured AccountingService and Person markup with hasCredential get verified and cited. Firms without it have to be inferred, and AI engines often choose not to bother inferring.

This is the implementation guide. Five schema types, copy-paste JSON-LD, and the deployment patterns that work for accounting firm websites.

For the strategic context, see the pillar on AI SEO for CPA firms, the E-E-A-T post, and the broader schema markup guide. For a structured engagement, see our AI SEO services for accountants.

Why schema matters more for accounting in 2026

Three reasons:

YMYL verification. AI engines verify credentials before citing financial content. Schema is the first line of verification.
Entity disambiguation. “Smith & Co CPAs” in Texas and “Smith & Company CPA” in Florida are different entities. Schema is how AI engines tell them apart.
Specialty extraction. knowsAbout and serviceType fields let AI engines understand exactly what specialty areas your firm serves.

The five schema types every accounting firm needs

1. AccountingService schema on the homepage

The parent schema for the firm itself.

{
  "@context": "https://schema.org",
  "@type": "AccountingService",
  "name": "Smith & Co CPAs",
  "image": "https://example.com/logo.png",
  "url": "https://example.com",
  "telephone": "+1-512-555-0100",
  "email": "info@example.com",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "1500 W 5th St",
    "addressLocality": "Austin",
    "addressRegion": "TX",
    "postalCode": "78703",
    "addressCountry": "US"
  },
  "geo": {
    "@type": "GeoCoordinates",
    "latitude": 30.2672,
    "longitude": -97.7431
  },
  "areaServed": [
    { "@type": "State", "name": "Texas" },
    { "@type": "Country", "name": "United States" }
  ],
  "knowsAbout": [
    "Real estate tax",
    "Cost segregation studies",
    "1031 exchanges",
    "Short-term rental taxation",
    "S-Corp election",
    "Multi-state tax compliance"
  ],
  "priceRange": "$$$",
  "aggregateRating": {
    "@type": "AggregateRating",
    "ratingValue": "4.9",
    "reviewCount": "47"
  }
}

The knowsAbout array is critical. List your firm’s actual specialty areas. AI engines use this directly when matching queries to firms.

2. Person schema with credentials for every CPA

Every CPA on staff needs a dedicated bio page with Person schema and hasCredential markup.

{
  "@context": "https://schema.org",
  "@type": "Person",
  "name": "Jane Smith",
  "honorificSuffix": "CPA",
  "image": "https://example.com/jane-smith.jpg",
  "url": "https://example.com/team/jane-smith",
  "jobTitle": "Managing Partner",
  "telephone": "+1-512-555-0101",
  "email": "jane@example.com",
  "worksFor": {
    "@type": "AccountingService",
    "name": "Smith & Co CPAs",
    "url": "https://example.com"
  },
  "knowsAbout": [
    "Real estate tax",
    "Cost segregation studies",
    "Short-term rental taxation"
  ],
  "hasCredential": [
    {
      "@type": "EducationalOccupationalCredential",
      "credentialCategory": "license",
      "name": "Texas CPA License",
      "identifier": "12345",
      "recognizedBy": {
        "@type": "Organization",
        "name": "Texas State Board of Public Accountancy"
      }
    },
    {
      "@type": "EducationalOccupationalCredential",
      "credentialCategory": "license",
      "name": "California CPA License",
      "identifier": "67890",
      "recognizedBy": {
        "@type": "Organization",
        "name": "California Board of Accountancy"
      }
    }
  ],
  "alumniOf": {
    "@type": "CollegeOrUniversity",
    "name": "University of Texas at Austin"
  },
  "memberOf": [
    {
      "@type": "Organization",
      "name": "American Institute of CPAs"
    },
    {
      "@type": "Organization",
      "name": "Texas Society of CPAs"
    }
  ]
}

The hasCredential array with identifier and recognizedBy is what makes the credential verifiable. AI engines use this for cross-reference against state board databases.

3. Article schema with author attribution on every blog post

Every accounting article needs Article schema with full author attribution.

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Cost Segregation for Short-Term Rentals: A 2026 Guide",
  "image": "https://example.com/cost-seg-cover.jpg",
  "datePublished": "2026-03-15",
  "dateModified": "2026-05-20",
  "author": {
    "@type": "Person",
    "name": "Jane Smith",
    "honorificSuffix": "CPA",
    "url": "https://example.com/team/jane-smith"
  },
  "publisher": {
    "@type": "AccountingService",
    "name": "Smith & Co CPAs",
    "logo": {
      "@type": "ImageObject",
      "url": "https://example.com/logo.png"
    }
  },
  "mainEntityOfPage": {
    "@type": "WebPage",
    "@id": "https://example.com/blog/cost-segregation-short-term-rentals"
  }
}

The author.url linking to the CPA’s bio page is the critical attribution link. AI engines follow that link to verify credentials.

4. FAQPage schema for FAQ sections

Most accounting content has FAQ sections. Mark them up.

{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "Can short-term rental owners use cost segregation?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, short-term rental owners can use cost segregation studies to accelerate depreciation on their rental properties. This is especially beneficial when combined with bonus depreciation, which remains at 60% for 2026 before scheduled phase-down."
      }
    },
    {
      "@type": "Question",
      "name": "Does cost segregation work for properties under $500K?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes, but the cost-benefit analysis is tighter. For properties under $500K, expect to recover 5x to 10x the cost of the study in first-year tax savings rather than the 15x to 25x ratio typical of larger properties."
      }
    }
  ]
}

Answers should be 50 to 100 words. Too short and they get filtered. Too long and they do not get cited.

5. Service schema for individual service pages

Each service or specialty page should have Service schema.

{
  "@context": "https://schema.org",
  "@type": "Service",
  "name": "Cost Segregation Studies",
  "provider": {
    "@type": "AccountingService",
    "name": "Smith & Co CPAs"
  },
  "areaServed": [
    { "@type": "State", "name": "Texas" },
    { "@type": "Country", "name": "United States" }
  ],
  "serviceType": "Tax planning and depreciation analysis",
  "description": "Engineering-based cost segregation studies for commercial and residential rental properties..."
}

Implementation rules

Use JSON-LD in the page head

Best for Google parsing and easiest to maintain. Microdata embedded in HTML is harder to manage and less reliably extracted.

Match schema to visible content

If schema says you serve five states, your website content should reflect that. Schema-content mismatch is treated as deceptive.

Keep credentials current

License numbers expire. Credentials change. Schema should reflect current status. Stale schema with expired credentials is worse than no schema.

Validate every change

Use https://validator.schema.org/ and Google’s Rich Results Test. Errors break the entire schema block. Warnings are usually safe to ignore.

Avoid schema bloat

One AccountingService block on the homepage. One Person block per CPA bio page. One Article block per blog post. Stacking redundant or contradictory schema gets filtered.

Deployment patterns

Manual JSON-LD in page templates

Best control, requires a developer once. Most accounting firms can deploy core schema this way and have it run unchanged for years.

WordPress with Rank Math or Yoast Premium

Both support custom schema templates. Most accounting firm WordPress sites can deploy via plugin.

Headless CMS or custom platform

If your site runs on a headless CMS (Sanity, Contentful) or custom platform, schema can be generated dynamically from content metadata. Best long-term scalability.

What this gets you

A firm with full schema implementation:

Verifiable credentials feed AI engine extraction
Specialty areas explicitly machine-readable
Author attribution chain connects content to credentialed CPAs
FAQ sections eligible for rich results and AI Overview citation
Entity disambiguation from similar-named firms

The cumulative effect over 12 to 24 months is significantly higher AI citation rates and stronger ranking for specialty queries.

FAQs

Will schema markup directly improve rankings?

Not by itself. Schema makes pages more eligible for rich results, easier for AI engines to verify, and clearer for entity disambiguation. The downstream effect on visibility is significant, but it is not a direct ranking factor.

How long until schema starts working?

Google reprocesses schema within days of a re-crawl. AI engines re-evaluate sources on a slower cadence, typically 2 to 8 weeks. Plan for visible effect within 30 to 90 days of full deployment.

What about firms with multiple offices?

Each office can have its own AccountingService block with location-specific address and geo coordinates. Link them as branches of a parent organization if applicable.

Can I include staff who are not CPAs?

Yes, with accurate credentials. Tax preparers, EAs, bookkeepers, and admin staff can have Person schema without hasCredential for CPA, but should include any credentials they do hold (EA, CITP, MST).

What if I do not have any reviews to put in aggregateRating?

Omit the field entirely rather than including invented numbers. AI engines cross-reference review counts and inventing them gets the schema flagged.
