Disclosure: Zamp makes sales tax software and a managed filing service, and this page compares Zamp with TaxValet. Facts about TaxValet come from TaxValet's own public pages and its downloadable pricing guide, checked on November 6, 2026. We say where TaxValet fits better. How we compared
Short answer
- Both do the work for you. A team registers you, files and pays your returns, and handles state notices.
- TaxValet publishes a price range. Its pricing guide also gives prices per state and a $3,500 setup fee. It doesn't calculate tax at checkout.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
- Zamp (our product) is priced by quote (see Zamp's entry). It calculates tax on its U.S. plan and also files in Canada.
Both are services, not software you run yourself. So the choice between TaxValet and Zamp comes down to four practical questions: how each charges, what costs extra, who calculates tax at checkout, and how onboarding works. We answer each below, using TaxValet's own figures.
TaxValet vs Zamp at a glance
Options are in alphabetical order.
| TaxValet | Zamp (our product) | |

What's included and what costs extra
TaxValet's pricing page promises "No hidden fees, overage charges, or surprise add-ons". Its Additional Fees page says "Most clients will not have additional fees (outside of opening/ closing sales tax permits) once the onboarding process is complete." It also publishes a list of fees for specific jobs, which is more than most managed services do. So the TaxValet prices below come from its own fee list. Zamp publishes what it covers but not its price, so some Zamp cells say "ask".
| Item | TaxValet | Zamp (our product) |
|---|---|---|
| Setup and onboarding | $3,500 one-time, plus about 10 hours of your time (pricing guide) | Not published. One G2 reviewer mentions an upfront setup payment, so ask what your quote includes up front |
| Late returns due before you start | $95 per return (Additional Fees page; its April pricing guide says $90) | Not published; ask |
| Registrations at onboarding | Part of onboarding; free | Handled by Zamp's team (see Zamp's entry for what the price includes). Ask whether state registration fees are passed on to you |
| Registrations after onboarding | $290 per state to open or close a permit (Additional Fees page). Its comparison pages list $250 and $275 per permit | Zamp alerts you at 80% of a state's threshold, and its team registers you when you cross it |
| Local returns | $35 per locality per month (pricing guide) | Filed, including home-rule local returns in states such as Colorado and Alaska |
| Back taxes and voluntary disclosures (VDAs) | Past exposure reviewed at onboarding. VDAs cost $4,000 each and are "Typically identified during new client onboarding" (Additional Fees page). Its comparison pages list $3,500 and $3,700 per VDA | Zamp agrees a plan with you, "from back returns to a voluntary disclosure", and does the work. Ask whether it's in your quote |
| Other occasional fees | After onboarding: penalty waiver requests $125 each (free during onboarding when they save at least $250 a state), amended returns $120 each, payment plans $245 each (Additional Fees page) | Not published; ask |
| Specialty returns (gross receipts tax, e-waste fees) | Listed as handled | Not stated on zamp.com; ask |
| Use tax payments | Listed as handled (its comparison page) | Not stated on zamp.com; ask |
| Tax calculation | Not offered. You may need a tool such as AvaTax, billed by that tool | Included on the U.S. plan (rooftop-accurate) |
| More transactions | "We will never charge your business extra fees for processing additional transactions" | See Zamp's entry |
TaxValet's prices for specific jobs come from its Additional Fees page, which is linked from its pricing guide. We checked it on November 9, 2026, and it's the newest of its price sources. Its pricing guide (file dated April 21, 2026) says "Additional fees may apply for local filings ($35/locality/mo), VDAs, or new permits opened after onboarding." Its two comparison pages give lower prices for some jobs, and we note those where they differ.Sources: TaxValet+2TaxValetTaxValet Additional Feesthetaxvalet.com/additional-feesFirst checked · Last checked TaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked TaxValetZamp vs TaxJar vs TaxValet (TaxValet comparison page)thetaxvalet.com/compare/zamp-vs-taxjar-vs-taxvalFirst checked · Last checked
What TaxValet costs at 3, 5, 10 and 20 states
TaxValet's pricing guide sets a base monthly fee by your annual US revenue. Then it adds $65 per state per month. So every extra state adds $780 a year.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked

Zamp is priced by quote. See Zamp's entry below.
How we calculated this. Each monthly price is TaxValet's base fee for your revenue ($500, $750 or $1,000 a month) plus $65 for each state. The yearly price is that monthly price times 12. Source: TaxValet pricing guide, file dated April 21, 2026. We don't show the revenue bands above $50M ($1,500 and $1,750 base). Some states charge their own registration fee, which is extra with any provider.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
- The first year adds the $3,500 setup fee. At 3 states in the $1M–$5M band, that's $11,840. At 20 states in the $5M–$25M band, it's $28,100.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
- Local returns add $420 a year each ($35 a month per locality).
- TaxValet's two price sources don't agree. The guide says "most clients pay between $565 and $1,700 per month" and the average is $1,600. Its pricing page, checked today, says "Typically ranges from: $1k - $4k Per month." Three of the 12 figures above fall below that $1,000 floor. Use the rate card as a guide, and ask TaxValet whether it still applies.Sources: TaxValet+1TaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked TaxValetTaxValet results and pricingthetaxvalet.com/results-and-pricingChecked
- Tax calculation may cost extra. If your checkout can't calculate tax, TaxValet's guide says you may need a third-party plugin such as AvaTax. The tool bills you for that, not TaxValet.
With TaxValet, you can estimate your full price before any call. Zamp doesn't publish one. So the fair comparison is TaxValet's first-year total against Zamp's written quote for the same states.
How onboarding works with each
Both start by reviewing where you owe tax and what you missed. Each company describes its own process differently, so we don't compare their timings directly.
TaxValet. A dedicated onboarding manager reviews where you have nexus, registers permits and reviews past transactions. The manager also works out any back taxes and sets up tax collection. Past exposure is handled "through voluntary disclosure agreements or other strategies". The guide says this "typically takes less than 60 days" and needs about 10 hours of your time. Billing for the monthly service starts on the first of the month after onboarding begins.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
Zamp. zamp.com lists "white-glove onboarding" and a dedicated point of contact. Registrations typically take 2 to 4 weeks per state, "often faster", and Zamp can register you retroactively. Shopify order history is imported free. If you're switching from another provider, the old one stays live until Zamp confirms it is filing. Zamp says "Most teams switch within a week", and it takes over at the end of a filing period.Sources: Zamp+1ZampZamp registrationszamp.com/feature/registrationsFirst checked · Last checked ZampZamp buyout programzamp.com/buyoutChecked
TaxValet
TaxValet is an outsourced sales tax department for US sellers. Its team takes care of returns, payments, permits, state mail and audits. It also publishes more of its pricing than most managed services.
US sellers with $1M–$50M in annual sales who want a price before the first call. It also suits sellers who want one team to handle specialty returns, use tax and their store's tax settings. Its pricing guide targets that revenue range with a published rate card, and its site lists those services.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
TaxValet at a glanceFrom TaxValet’s own pagesZamp (our product)
Zamp is a managed sales tax service for ecommerce and SaaS sellers, including Shopify and marketplace sellers. Its team registers you, files and pays your returns, and replies to state notices, for one quoted price. You approve returns in one monthly email, and its U.S. plan calculates tax.
ecommerce and SaaS sellers on several channels, with no one in-house who owns sales tax. That includes sellers who also file in Canada. Every subscription includes a team that registers, files, pays and deals with the state. The U.S. plan includes calculation, and there's a U.S. + Canada plan.
Zamp at a glanceFrom zamp.com"The onboarding team provided a step-by-step guide and followed up on action items, ensuring a smooth transition to becoming a client."
What G2 reviewers say about Zamp
Zamp is rated 4.7 (Source: G2.com, Inc.) out of 5 from 58 reviews on G2 (Source: G2.com, Inc.). We read 57 of them (16 Incentivized). About 40 praise responsive human support. 11 raise cost or pricing as a downside, while 10 praise the pricing. Three say state mail still reaches them, and two raise problems getting help to close state accounts. We counted these by hand from the full review text. TaxValet's G2 reviews weren't in the review collection we used, so this section covers Zamp only.Source: G2G2Zamp Reviewsg2.com/products/zamp/reviews
"The automated emails are actually relevant, not noise, and whenever I reply to one I get a capable human right away."
"The upfront payment for set up was quite a big nut to swallow."
When Zamp isn't the right choice
- You want the full price before any call. TaxValet's guide lets you work it out: $695 a month at 3 states in the $1M–$5M band, plus $3,500 setup.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
- You want the guarantee to name tax due, not only penalties and interest, on a fully managed account. TaxValet's published wording does (see its agreement).
- You need specialty returns such as California e-waste or gross receipts tax filed with your sales tax. TaxValet lists them; zamp.com doesn't.
- You want no portal at all, with everything done by email and phone. TaxValet works that way by design.
- You file a few returns a year and will handle state notices yourself. Software that charges per filing is built for that. Kintsugi Starter charges $75 per filing or registration, so 12 returns cost $900 a year. See TaxJar alternatives.Source: KintsugiKintsugiKintsugi pricingtrykintsugi.com/pricingChecked
When TaxValet isn't the right choice
- You need tax calculated at checkout or by API without buying a separate tool.
- You sell into Canada. TaxValet covers US sales tax.
- You want a dashboard to check filings and nexus yourself.
- You need a published security certification for vendor review. TaxValet's site doesn't state one.
- You can't commit to a 1-year term, which its pricing guide describes. Ask Zamp for its term too.
- You're under $1M in sales. Its guide targets $1M–$50M. Its rate card starts at the $1M–$5M band ($565 a month at one state, $10,280 in year one with setup). It publishes no price below $1M.Source: TaxValetTaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked
TaxValet alternatives
Other options where a team does the work include Zamp and Kintsugi's Scale and Premium plans. Kintsugi lists a custom flat monthly price for both and says "Our team handles the ops work for you". It handles notices you forward to it, and Premium adds VDA management by its Tax Ops team. Numeral's in-house team files returns and sorts notices, with pricing per return ($75 per return filed). But its help center says you usually remain the state's main contact on a notice; see Zamp vs Numeral.

TaxValet vs Zamp: FAQs
Is TaxValet or Zamp cheaper?
It depends on your quote. TaxValet's pricing page says "typically" $1,000–$4,000 a month. Its April 2026 guide gives $500–$1,750 a month plus $65 per state, and a $3,500 setup fee. Zamp is priced by quote; see Zamp's entry.

How much does TaxValet cost?
TaxValet's pricing page says it "typically" ranges from $1,000 to $4,000 a month (checked Nov 6, 2026). That's $12,000–$48,000 a year. Its April 2026 pricing guide gives a rate card. For $1M–$5M sellers, it's $695 a month at 3 states and $1,800 at 20 states, plus a $3,500 setup fee in the first year. The two sources disagree, so your quote decides. Extras include local returns ($35 per locality a month, per the guide). Its Additional Fees page lists permits opened after onboarding ($290 per state) and VDAs ($4,000 each). But that page says most clients pay no extras after onboarding, apart from permits.Sources: TaxValet+2TaxValetTaxValet Services Summary 2026 (pricing guide, PDF)thetaxvalet.com/hubfs/TaxValet%20Services%20SummFirst checked · Last checked TaxValetTaxValet results and pricingthetaxvalet.com/results-and-pricingChecked TaxValetTaxValet Additional Feesthetaxvalet.com/additional-feesFirst checked · Last checked
Does TaxValet calculate sales tax at checkout? Does Zamp?
TaxValet doesn't. It uses your store's own tax settings, or recommends and helps set up a third-party tool such as AvaTax. Zamp's U.S. plan includes rooftop-accurate calculation. On Shopify, Shopify Tax calculates at checkout and Zamp files the returns.
Is Zamp DIY sales tax software?
No. Every Zamp subscription is a managed service. Zamp's team registers you, files, pays each state and replies to notices, and you approve one monthly email. TaxValet's comparison page describes Zamp as DIY software. zamp.com and Zamp's G2 reviews describe a team doing the work.
Do both handle registrations, notices and audits?
Yes. TaxValet registers permits at onboarding, handles state mail and calls, and represents you in up to 3 audits in 12 months ($4,000 for more than three). Zamp registers you in any state and starts notice responses within 2 business days. It lists audit support and representation on its paid plans.Sources: TaxValet+2TaxValetTaxValet vs sales tax softwarethetaxvalet.com/taxvalet-vs-sales-tax-softwareFirst checked · Last checked TaxValetTaxValet Additional Feesthetaxvalet.com/additional-feesFirst checked · Last checked ZampZamp notice managementzamp.com/feature/notice-managementFirst checked · Last checked
What do the TaxValet and Zamp guarantees cover?
TaxValet's guide covers penalties, interest and tax due that result from its work (see its agreement). Its pricing page covers penalties from late filings its team causes. The Zamp Commitment covers penalties or interest from calculations or filings that Zamp manages, with conditions. Its accuracy cover for API customers is capped at 12 months of fees.Source: ZampZampZamp Commitmentzamp.com/zamp-commitmentChecked
Do TaxValet or Zamp require a contract?
TaxValet's pricing guide describes a 1-year term that renews annually. Billing starts on the first of the month after onboarding begins. Zamp doesn't publish its contract term, so ask for it in your quote.
Do TaxValet or Zamp cover Canada?
TaxValet covers US sales tax. Zamp's published plans are U.S. and U.S. + Canada. The Canada plan includes GST, HST, PST and QST registrations and returns.
Are TaxValet and Zamp SOC 2 certified?
Zamp completed a SOC 2 Type II examination with zero exceptions (Prescient Assurance, April 20 to August 30, 2026), and the report is available under NDA. TaxValet's site doesn't state a security certification. Ask it directly if your vendor review needs one.
