Send us your tax notices, or make TaxDo your address of record. Either way a tax specialist reads every notice, tells you plainly what it requires and prepares the response for your signature.
Tax authority correspondence does not arrive in one place, does not announce its urgency, and does not wait. Most of it lands at an address or an inbox nobody owns.
An unanswered information request becomes an estimated assessment. That becomes a lien or a suspended registration. No one at the authority has to decide anything for this to happen — each step simply follows the last.
Paper posted to a US address you do not staff, PDFs sent to a shared inbox, portal alerts that nobody ever logs into. By the time a notice reaches anyone who can actually act on it, half of its response window is already gone.
A notice spells out your revenue, your registrations and what the authority believes you owe. Delivered to a front desk or a shared inbox, it is read by whoever opens the post first — long before the person who should see it.
A nexus questionnaire means a state already believes you owe it tax. Read late, it is a problem you manage on the state’s terms and timeline. Read on arrival, it is still a decision you get to make yourself, while it is cheap.
Each one means something different and each one runs on a different clock. Most of the damage comes from not knowing which one you are holding.
The state thinks you may already owe there and wants it confirmed in writing, e.g. the Texas Nexus Questionnaire (Form AP-114).
It sets your start dateAlso called a notice of proposed assessment: tax the state says you owe, often estimated because nothing was filed.
Protest window, set on the noticeA return the state expected has not arrived. Left alone it becomes an estimated assessment.
Escalates automaticallyCharges added to a period already assessed — frequently abatable if answered in time.
Abatement window appliesMonthly instead of quarterly, from a date you did not choose. Missing the first one restarts the cycle.
Effective from a stated dateAn examination is opening. What you send in the first response shapes everything after it.
Response date set on the noticeYour authority to collect is being suspended — which can stop you selling in that state.
Short cure periodCollection has begun against accounts or assets. The window to stop it is the shortest of any notice.
Act immediatelyEvery state names these differently — a Notice of Determination in California, a Notice of Tax Due in Texas, an Assessment in New York. Different names, and each one sets its own deadline.
The handling is the same either way. What changes is whether a notice can sit unopened before the right person sees it.
You give the authorities our address. Every notice arrives directly to a desk staffed by people who read tax correspondence for a living — digitised, classified and on the clock the same day.
Requires a change of address with each authority. We prepare those filings and handle it jurisdiction by jurisdiction.
Notices keep arriving wherever they arrive today — your office, your registered agent, your accountant. When one turns up, upload it to us and the tax team takes it from there.
One gap remains: the clock starts when you upload it, not when it arrived. If a notice sits on a desk for three weeks, nobody can give those weeks back — which is why most customers move to the address of record eventually.
However a notice reaches us, everything after that runs on a clock we manage.
Delivered to the TaxDo address, or uploaded by you — captured and digitised either way.
Authority, entity, jurisdiction, notice type and the statutory response window identified and logged.
A specialist reads it and tells you what it is, what it requires, and what happens on the first day after the deadline.
The response is drafted for you, discussed in secure messaging and signed with e-signature — all in TaxDo Vault.
The response goes out, the deadline is cleared, and you are told what — if anything — comes next.
Where a jurisdiction allows it and you authorise it, we submit the response for you. Where it requires a signed power of attorney, we put that in place first.
Registering for US sales tax generally requires a US address to complete the registration and to receive correspondence from the state. We are that address — so a notice is read and on the clock the day it arrives, not weeks after it was delivered.
For small and medium businesses, sales tax notices arrive from several states and a finance lead already has a job. We read each one, tell you what it means, and prepare the response — so a missed window never turns into an assessment.
For global enterprises, twenty registrations means twenty correspondence streams, each on its own clock. One register of what is outstanding everywhere, with per-entity permissions underneath it.
Keep them. We handle the arrival, the clock and the preparation; they keep doing what you engaged them for. They are looped in on every notice as it is handled, instead of receiving forwarded email.
Reading your correspondence carefully is how the next obligation gets found early — while it is still cheap to fix.
The state already believes you have an obligation there. We register you where you should be registered — prepared and submitted, with the registration letter filed for you the moment it is issued.
Global Indirect TaxMonthly instead of quarterly, from a date you did not choose. Returns prepared, validated and filed on your behalf in the jurisdictions you pick — without moving to a full platform.

Tax notice management is the handling of the letters tax authorities send — receiving them, working out what each one actually requires, and answering it before its deadline. TaxDo runs it as a service: every notice is digitised the day it lands, classified by authority, entity and type, reviewed by a tax specialist, and returned to you with a plain explanation of what it is, what it requires and when it is due, with the response prepared for your signature.
We take over every notice from the moment it reaches us — at our address if you make TaxDo your address of record, or uploaded by you if you keep your own. Every notice is digitised the day it lands, classified by authority, entity and type, reviewed by a tax specialist, and returned to you with a plain explanation of what it is, what it requires and what the deadline actually is — with the response prepared for your approval and signature.
We prepare the response and, where you authorise it and the jurisdiction permits, submit it for you. Some jurisdictions restrict who may correspond on a taxpayer’s behalf and require a signed power of attorney; where that applies we put it in place first, and where it cannot apply we prepare everything for your signature instead.
No. There are two ways to run it. Make TaxDo your address of record so notices arrive directly to us — the version where nothing depends on anyone noticing an envelope. Or keep your existing address and upload each notice to us when it turns up; a tax specialist reviews it, tells you what it requires and prepares the response exactly the same way. The only difference is when the clock starts: on arrival in the first case, on upload in the second.
A service, delivered through TaxDo Vault. What you are buying is the handling: the address, the review, the deadline management and the prepared response.
Digitisation happens the day it lands. Specialist review follows on a defined turnaround, and anything with a short statutory window — a lien, a levy, a permit revocation — is escalated ahead of the queue rather than taken in order.
No. We tell you what is owed, whether it is correct, and whether it can be reduced or abated — then you decide and you pay. We never hold or move client funds. Where a payment plan is the right answer, we prepare the request.
Correspondence from any tax authority — US state revenue departments, federal agencies and non-US authorities. Registration confirmations, filing frequency changes, nexus questionnaires, assessments, penalty and interest notices, information requests, audit letters and account closures.
Nothing is sent without your approval. The recommendation is exactly that: you see what the notice requires, what we suggest, and why. If your advisor takes a different view, they can raise it with us before anything is sent. Only what you sign goes out.
That is the most common reason businesses use this. Sales tax notices arriving from several states with nobody internally whose job it is to read them is exactly the gap the service closes.
They are usually the most urgent thing in the account. An assessment covering periods you never filed is not a notice problem, it is an exposure problem — we quantify it and tell you whether a voluntary disclosure closes it more cheaply than answering the notice on its own terms.
Start with what the notice actually says: which authority sent it, which tax and period it covers, what it asks for and the date it must be answered by. That date matters most, because replying on time is what protects your right to appeal. Check the figures against your own filings before you pay or dispute anything. If it is correct, pay it or ask for a payment plan. If it is not, answer as the notice instructs, with supporting documents, and keep a copy of everything. The same applies to an IRS notice and a state department of revenue letter. TaxDo does this for you: we digitise the notice, a tax specialist explains it and its deadline, and we prepare the response for your signature.
The notice does not go away, and your position usually gets worse. If a return was expected and not filed, the authority can issue an estimated assessment, and it is then for you to show the figure is wrong. Penalties and interest keep adding to the balance. You can also lose the right to dispute it, because replying by the due date is what protects your appeal rights. An unpaid assessment can lead to a lien, a legal claim against your property, and then a levy, which actually takes it. Ignored notices can also end in a suspended permit to collect. Tax notice management is built to prevent that: every notice is read by a tax specialist, its deadline is flagged and a response is prepared for your signature.
We will tell you what each one actually required, what is still open, and what the deadline really was.
