Yes. If the problem is missed multistate sales-tax return deadlines, you want a provider that does more than calculate tax—it should prepare, file, and remit returns automatically.
If you qualify as a Streamlined Sales Tax “CSP-compensated seller,” participating states can pay for CSP services, meaning sales-tax calculation/reporting services can be provided at no cost in participating states. The current certified-provider list includes Avalara, TaxCloud, Sovos, AccurateTax, and Avior.
Since you're already accumulating penalties, I'd separate the project into two parts:
If you tell me which states you file in, roughly how many monthly transactions/orders you have, and what accounting/e-commerce system you use (QuickBooks, Shopify, NetSuite, etc.), I can compare the providers on pricing, integrations, automated filing/remittance, and handling of your existing late returns.
Several major software providers specialize in automating multi-state sales tax calculation, filing, and remittance to help you avoid future penalties. - [Avalara](https://www.avalara.com/us/en/index.html) is one of the most widely used platforms.

Automated sales tax filing providers include:
Since you’re already paying penalties, prioritize vendors that handle returns filing and remittance, not just tax-rate calculation. Also check whether they can manage your existing state registrations, missed filings, and penalty exposure. Streamlined Sales Tax lists certified providers such as Avalara, Sovos, TaxCloud, AccurateTax, and Avior.
For a multi-state business, a typical shortlist would be Avalara vs. Sovos vs. Vertex (larger/complex operations) or TaxJar/TaxCloud (smaller ecommerce-focused operations).

Yes. If the main problem is missing filing deadlines and paying penalties across multiple states, I’d focus on providers that actually prepare, file, and remit returns, not just calculate sales tax.
Since you're already incurring penalties, I'd prioritize a provider that can take responsibility for the entire compliance workflow:
| Provider | Automated filing | Remittance | Nexus/registration | Notice handling | Best fit |
|---|---|---|---|---|---|
| Avalara | Yes | Yes | Yes | Yes | Broad/multi-state businesses |
| Zamp | Yes | Yes | Yes | Yes | Hands-off compliance + expert support |
| TaxJar/Stripe | Yes* | Yes* | Yes | Some | Stripe/ecommerce businesses |
| Sovos | Yes | Yes | Yes | Yes | Larger/complex organizations |
| Vertex | Yes | Yes | Yes | Yes | Enterprise/complex ERP |
*Depending on the specific Stripe/TaxJar product and filing locations.
One important distinction: don't buy a product merely because it says "sales tax automation." Some products automate calculation but leave you responsible for actually filing returns. For your problem, you want automated returns + payment/remittance + deadline tracking + notices.
If you tell me what you sell, approximate annual revenue/transaction volume, which states you're registered in, and what system you use (Shopify, Amazon, Stripe, NetSuite, QuickBooks, etc.), I can narrow this to the 2–3 best options and compare estimated pricing and features.

Missing multi-state sales tax deadlines is a costly problem, as states often impose severe penalties (ranging from 5% to 10% per month) plus daily interest, even on zero-tax returns.[](https://www.ceretax.com/blog/california-sales-tax-filing-deadlines-penalties-2026)…
Missing multi-state sales tax deadlines is a costly problem, as states often impose severe penalties (ranging from 5% to 10% per month) plus daily interest, even on zero-tax returns.
To eliminate manual filing errors and late fees, several industry-leading platforms offer automated sales tax compliance software tailored to specific business types:
Top Automated Sales Tax Solutions
Core Automation Capabilities
When choosing a platform, ensure it handles the full compliance lifecycle to permanently stop late penalties:
How to Begin
To fix your immediate problem, most of these platforms offer a historical Sales Tax Risk Assessment . This tool syncs with your current billing platform, maps out exactly where you have missed deadlines, and provides an immediate path to file retroactive returns (back-filing) to get you caught up with state authorities.

Yes. If the problem is multiple states, different filing deadlines, and penalties for missed returns, you want a platform that does more than calculate sales tax—it should prepare, file, remit, and track returns automatically.
There's also an important potential cost-saving angle: Streamlined Sales Tax (SST) has certified providers including Avalara, TaxCloud, Sovos, AccurateTax and Avior. Qualifying businesses in participating states can have CSP services—including return preparation, filing and remittance—provided at no charge because the states compensate the provider.
Since you're already paying penalties, I would compare them specifically on:
If you tell me roughly how many states you file in, what accounting/e-commerce system you use (QuickBooks, NetSuite, Shopify, etc.), and your approximate annual sales, I can narrow this to the 2–3 best options and compare likely cost and capabilities for your situation.

Yes. If the main problem is missing filing deadlines across multiple states, I’d focus on providers that actually prepare, file, and remit returns automatically, rather than software that merely calculates sales tax.
Since you're already incurring penalties, don't evaluate these solely on tax-rate accuracy. I'd prioritize:
One important distinction: a Certified Automated System (CAS) can calculate and prepare tax while leaving filing responsibility with you, whereas a Certified Service Provider (CSP) can take on much more of the filing/compliance workload.
For a business specifically trying to stop penalties from recurring, I'd put Avalara, TaxJar, and Sovos at the top of the initial comparison. TaxJar is especially worth considering if you're primarily e-commerce; Avalara or Sovos may make more sense if your footprint is complex and includes lots of local jurisdictions.
