The short version

  • Only TaxJar has a free tier, so it costs nothing to try first.
  • Each has a real cost: Paychex pricing is quoted rather than published and varies between clients and between renewals, with separate charges for each payroll run, off cycle payments and year end processing, so two similar businesses regularly pay very different amounts for the same service and comparing quotes is difficult by design.; TaxJar both published plans include only 200 orders per month, so higher volume costs more
  • They diverge on capability: Paychex covers Payroll processing, TaxJar covers Tax calculation.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Paychex

  • Pricing is quoted rather than published and varies between clients and between renewals, with separate charges for each payroll run, off cycle payments and year end processing, so two similar businesses regularly pay very different amounts for the same service and comparing quotes is difficult by design.
  • Charging per payroll run rather than per month penalises employers who pay weekly or who run frequent off cycles, so a business with hourly staff on a weekly cycle pays several times what a monthly salaried business of the same size pays.
  • Migrating mid year requires transferring year to date wage and tax figures for every employee in every jurisdiction, so in practice companies switch only at a calendar year end, which leaves you locked to the incumbent for the rest of the year whatever the service is like.
  • The service model depends on an assigned representative, and reported experience varies sharply with who that person is and how often the assignment changes, which means the quality of what you bought is not a property of the product you evaluated.
  • It is a United States service, so a company with employees abroad still needs a separate payroll provider in each country, and the group has no single view of employment cost without building one outside the system.

TaxJar

  • Both published plans include only 200 orders per month, so higher volume costs more
  • The Starter plan at $39 per month allows only 3 data import integrations
  • AutoFile state filings are metered: Starter includes 2 credits a year and each extra filing costs $50, Professional includes 4 and each extra costs $55
  • Real time tax calculation API access requires the Professional plan at $99 per month
  • Phone support, a Customer Success Manager and a dedicated onboarding specialist require the Professional plan
  • The developer sandbox requires the Professional plan
  • The 10% saving requires annual billing

Answered from the vendors’ own pages

Paychex: How much does it cost?

Paychex quotes per client rather than publishing rates, and the structure typically includes a base fee plus a per employee per payroll charge with extras for year end and off cycle runs. Get the full fee schedule in writing, including what a mid year change of plan costs.

TaxJar: How much does TaxJar cost?

TaxJar pricing starts at $39/month for Starter and $99/month for Professional. Save 10% or more with annual pricing. A 30-day free trial is available.

Source
Paychex: Who is liable if payroll taxes are filed late or wrongly?

Contractually the provider generally accepts responsibility for errors it makes, but the employer remains the party the tax authorities pursue. Read the specific indemnity language rather than relying on the sales description.

TaxJar: What is the difference between TaxJar Starter and Professional?

Both plans handle up to 200 orders/month, but Professional includes phone support, dedicated success manager, 10 users, and more data integrations and API capacity.

Source
Paychex: Can I switch providers mid year?

Technically yes, but you must carry year to date figures across for every employee and jurisdiction, and errors there surface at year end on employee tax forms. Most businesses switch effective 1 January for that reason.

TaxJar: Does TaxJar offer discounts for annual billing?

Yes, TaxJar saves customers 10% or more when paying annually instead of monthly for both Starter and Professional plans.

Source
Paychex: What is the difference between the standard service and the professional employer organisation option?

Under the professional employer organisation arrangement Paychex becomes a co-employer for tax and benefits purposes, which changes your benefits access and some of your employment administration. It costs more and it is harder to unwind, so treat it as a different decision from buying payroll.

Paychex: Does it work with my accounting software?

It exports a general ledger file and connects to the mainstream accounting products. Confirm the mapping to your chart of accounts during onboarding, because a generic export means your bookkeeper recodes every run.

Paychex: Is it suitable if we only have a few employees?

It will serve you, but very small employers often find the per run charges and the service tiering expensive relative to self service payroll products. The case improves once multi state complexity or benefits administration enters the picture.
