How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Privacy note: get a Business Associate Agreement in writing before sending any protected health information through an online fax service, since a BAA is what makes the vendor accountable for HIPAA handling.
- BAA availability varies by tier: Fax.Plus offers a BAA only on Enterprise, eFax on Protect and Business plans, and iFax from Plus, while SRFax and Documo offer BAAs on request for healthcare plans.
- SRFax Healthcare Lite at 12.60 dollars per month for 200 pages is the strongest low-cost HIPAA entry, while Fax.Plus Enterprise at 79.99 dollars per month suits larger teams needing shared volume.
- Consistent with the B-22 fax article standard: a vendor with no published BAA or only self-attested compliance should not carry PHI, no matter how cheap the plan.
- All services here use AES 256-bit encryption in comparison reporting, but encryption alone does not equal HIPAA compliance without a signed BAA and proper configuration.

The best HIPAA-compliant online fax service
Starting price$12.60 per month
Free planNo
What we like- SRFax offers Healthcare Lite at 12.60 dollars per month, or 10.70 dollars per month billed annually in some comparisons, for 200 combined incoming and outgoing pages, with HIPAA and PHIPA included and a BAA available on request for healthcare plans. It suits healthcare providers and medical records management, with email-to-fax and printer driver workflows, transparent pricing, and the lowest overage rates in one comparison series. It undercuts its sibling eFax by a wide margin at entry level.
Watch out for- There is no free tier, OCR is a paid add-on, and a 25 dollar port fee applies in comparison reporting. The compliance story is older than competitors, with fewer modern certifications claimed. Price has crept up since the Consensus acquisition, so confirm current terms.

Best for: Enterprise and legacy integration4.5/5 on

Visit efax.com
Starting price$39.99 per month
Free planNo
What we like- EFax offers a 30-plus year track record with enterprise and legacy integration, plus niche healthcare interoperability. Personal plans start at 18.99 dollars per month for 200 pages, while the HIPAA-eligible Business plan costs 39.99 dollars per month for 500 pages, five users, and one number, with a BAA included. Protect plans are reported near 50 dollars per month in some comparisons. It suits larger practices and corporate healthcare deployments with 24/7 support.
Watch out for- The BAA sits on Business and higher plans, not Personal, so the 18.99 dollar entry price does not cover HIPAA use. Corporate arrangements are assessed separately, and pricing reports vary between Personal, Business, and Protect tiers, so confirm which plan carries the BAA before buying.
#3Fax.Plus
Best for: Best overall interface4.6/5 on
G2 (60 reviews, checked Oct 2026)
Visit fax.plus
Starting price$79.99 per month
Free planNo
What we like- Fax.Plus offers the best overall interface in comparison reporting, with Basic at 6.99 dollars per month annually for 200 pages, and an Enterprise plan at 79.99 dollars per month annually, or 99.99 dollars month-to-month, covering 4,000 shared billable pages, unlimited members, and two numbers, with a signed BAA and advanced security controls. It suits high-volume teams and budget-conscious SMBs for general faxing, with a 30 day trial on some plans.
Watch out for- The BAA is Enterprise tier only, so the 6.99 dollar Basic plan does not cover HIPAA use, a trap for buyers who compare entry prices alone. Enterprise pricing at 79.99 dollars per month suits larger teams better than solo practices. Additional usage, taxes, numbers, and licenses can affect the total.
#4iFax
Best for: Mobile-first HIPAA4.7/5 on
G2 (480 reviews, checked Oct 2026)
Visit ifaxapp.com
Starting price$24.99 per month
Free planNo
What we like- IFax offers mobile-first HIPAA faxing on a budget, with Basic at 12.49 dollars per month for 200 pages send only, and Plus at 24.99 dollars per month annually for 500 pages, one number, send and receive, e-signatures, and a BAA available on Plus and Pro plans. It suits individual users prioritizing mobile workflows, with iOS, Android, and web apps. A 7 day trial is available on some plans.
Watch out for- The BAA starts at Plus, not Basic, so the 12.49 dollar entry price does not cover HIPAA use. Plus pricing is reported at 24.99 to 30 dollars per month across sources, so confirm current terms. Mobile-first design suits individuals better than large teams needing centralized administration.
Starting price$25 per month
Free planNo
What we like- Documo offers dedicated faxing with broader document automation, with Solo at 25 dollars per month annually for 300 pages, one user, and one number, and a BAA available on request across plans. It suits solo practices willing to pay for OCR, AI document processing, and EHR integration, with iOS, Android, web, and email workflows. The BAA is not gated to a higher tier, unlike Fax.Plus or iFax.
Watch out for- Solo pricing at 25 dollars per month annually is high for low-volume faxing, and the annual-only commitment adds friction. It suits solo practices better than large teams, and the price is hard to justify if only basic faxing is needed. Confirm whether OCR and AI processing are included or add-ons on your plan.

Free planNo
What we like- RingCentral Fax suits high-volume teams and organizations considering fax alongside phone and video, with unified communications integration and HIPAA plus HITRUST claims in comparison reporting. A BAA is available, with current eligible fax service or communications configuration to be confirmed in a proposal. It suits organizations already on RingCentral that want fax inside the same platform.
Watch out for- Pricing reports conflict, from 17.99 dollars per month in one comparison to 27.99 dollars per user per month in another, so the price is listed as See website. BAA and covered service configuration must be arranged and confirmed for the quoted subscription, rather than assumed from the base plan. Standalone fax buyers get better value from SRFax or Documo.
Starting price$4.90 per month
Free planNo
What we like- Notifyre offers the lowest entry price here, at 4.90 dollars per month for receive faxing, with a free BAA included and transparent audit trails. It suits cost-sensitive practices needing compliant receiving without a large monthly commitment, with AES 256-bit encryption in comparison reporting. The free BAA inclusion is rare at this price point.
Watch out for- The 4.90 dollar plan covers receiving, so sending volume needs a higher plan or per-page pricing to be confirmed. The vendor is smaller than eFax or RingCentral, so support depth and integrations should be confirmed during evaluation. Contact is needed for a demo on some plans.
#8Concord
Best for: Low-volume healthcare faxing4.2/5 on
G2 (133 reviews, checked Oct 2026)
Visit concord.net
Starting price$10.95 per month
Free planNo
What we like- Concord offers FaxPro 100 at 10.95 dollars per month for 50 incoming and 50 outgoing pages, with three sending email addresses and a BAA available on request. It suits low-volume faxing plus wider healthcare document services, with a low fixed price for practices sending only a handful of faxes per month. The per-page economics suit infrequent senders.
Watch out for- Included volume is small at 100 total pages, so moderate users hit overages quickly. The BAA is available on request rather than automatic, so get it signed before sending PHI. Healthcare document service breadth beyond fax should be confirmed for your workflow.
How we chose
We ranked services on BAA availability and tier, encryption, audit trails, page allowances, EHR and API integration, and published pricing. Services earned credit for BAAs included on low tiers, signed BAAs without upgrade gates, transparent page pricing, and healthcare-specific features. We excluded services with no BAA path, since HIPAA use without a signed BAA is not compliant regardless of encryption claims. Figures come from published pricing and 2026 comparison reporting, and readers should confirm current terms directly, since BAA tier gates and page allowances change.
How to choose the right HIPAA-compliant online fax service
Start with the BAA, not the price: get a Business Associate Agreement in writing before sending any PHI, and confirm which plan tier carries it, since Fax.Plus gates the BAA to Enterprise, eFax to Business and Protect, and iFax to Plus. Next, check page volume honestly: 200 pages suits most small practices, while 4,000 shared pages on Fax.Plus Enterprise suits larger teams, and per-page overage rates matter once volume grows. Then check encryption and audit trails: AES 256-bit encryption at rest and TLS in transit, plus audit logs showing who sent and received each fax, are baseline expectations. Then check integrations: EHR connections, API access, and email-to-fax workflows decide whether faxing fits clinical operations or creates manual work. Finally, confirm configuration with the vendor, since a signed BAA alone does not make a deployment compliant if staff share logins, store faxes insecurely, or skip access controls.
Frequently asked questions
What is a BAA and why does it matter for faxing?
A Business Associate Agreement is a written contract in which the fax vendor agrees to handle protected health information under HIPAA rules. Without a signed BAA, the vendor is not accountable as a business associate, and sending PHI through the service is not compliant even if the service encrypts data.
Which fax service offers a BAA on the cheapest plan?
Notifyre includes a free BAA at 4.90 dollars per month for receiving, and SRFax offers a BAA on request for Healthcare Lite at 12.60 dollars per month. Documo offers a BAA on request across plans starting at 25 dollars per month.
Does Fax.Plus Basic cover HIPAA use?
No. Fax.Plus offers a BAA only on the Enterprise tier at 79.99 dollars per month annually, so the 6.99 dollar Basic plan does not cover HIPAA use despite the same brand name.
Is encryption enough for HIPAA compliance?
No. AES 256-bit encryption and TLS in transit are necessary but not sufficient. HIPAA compliance also needs a signed BAA, access controls, audit trails, and proper configuration, plus staff training and policies on the practice side.
How many pages do small practices need?
Most small practices manage on 200 pages per month, the standard entry allowance for SRFax, eFax Personal, Fax.Plus Basic, and iFax Basic. Larger practices should compare shared volume plans such as Fax.Plus Enterprise at 4,000 pages.
Can I use a free fax service for patient information?
No. Free services such as FaxZero and FaxBurner offer no BAA path in comparison reporting, so they should not carry PHI. Use a HIPAA-eligible plan with a signed BAA for any patient information.
