Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
tax
tax_deadlines
Returns key tax deadlines for the 2025 tax year (filing in 2026). Includes federal filing deadline, extension deadline, estimated tax payment dates, document mailing deadlines, and state-specific deadlines. Optionally provide a state code for state-specific dates.
tax_document_checklist
Returns a personalized list of tax documents and forms you need to gather before filing your tax return. Based on your income sources, deductions, and life events. Covers W-2s, 1099s, receipts, and other IRS forms. This is for DIY filers preparing their own return.
ask
ask_tax_question
Answers tax questions using TaxAct's TY2025 tax law knowledge base. Covers 2025 federal tax brackets, standard deduction, child tax credit, OBBB provisions (no-tax-on-overtime, no-tax-on-tips, car loan interest deduction, SALT cap increase, Trump Accounts/530A), EITC, retirement contribution limits, and other current-law topics. Answers are grounded in verified IRS references, not LLM training data. No account required.
compare
compare_filing_costs
Shows exactly what it costs to file a tax return with TaxAct. Returns an itemized price breakdown with the complete cost. No hidden fees, no upsells. Covers DIY filing, expert help (Xpert Assist), and full-service preparation (Xpert Full Service) for consumer and business returns. Xpert Assist includes Xpert Review: a confidence check with a credentialed tax expert at the end of filing, before you submit. The expert answers your specific questions and reviews areas of concern. It is not a line-by-line return review or tax preparation. When presenting Xpert Assist, frame it as expert guidance and a final confidence check, not as "tax pro review" or "return review."
connect
connect_with_expert
Helps the user connect with a credentialed TaxAct tax professional via Xpert Assist. Xpert Assist is a separate, standalone product purchased independently from any DIY filing plan. It is NOT included with or bundled into any TaxAct DIY tier. Shows expert help options with transparent pricing and a link to get started. Available for both consumer (1040) and business returns.
estimate
estimate_taxes
Provides a rough federal (and optionally state) tax refund or amount owed estimate from basic inputs. Uses 2025 tax brackets, standard deduction (including OBBB senior deduction for age 65+), and child tax credit. Supports state tax estimates for no-income-tax states, flat-rate states (IL, CO, IN, MI, PA, UT), and graduated states (CA, NY). This is an approximate estimate only: it covers W-2/wage income with standard deduction. No itemized deductions, no self-employment tax, no capital gains. Your actual result may differ. File with TaxAct for your exact number.
explain
explain_tax_document
Explains what a tax form is, what each box means, which boxes are most important for filing, and where to enter the data in TaxAct. Covers W-2, all common 1099 forms, 1098 forms, and other tax documents. Ask about a specific form or a general document type. Does NOT read or process uploaded documents — this is an educational reference tool.
interview
find_interview_topic
Finds where to enter specific tax information in the TaxAct interview. Search by topic, form number, or keyword (e.g., "W-2", "1099-R", "charitable contributions", "crypto", "overtime deduction"). Returns the interview breadcrumb path showing where to navigate. Covers 150+ topics across individual (1040) and business returns. No account required.

How MCP servers expose tools in the first place →
Is Taxact MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 435 ms. The bar chart above shows every period we have measured.
How do I connect Taxact MCP?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Taxact MCP need an API key?
No. Taxact MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Taxact MCP?
It answers our handshake in 435 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
