Look up current tax rates and brackets
Ask about a tax bracket or rate and Zeplik reads curated, dated tax data, then answers with the figure and the exact year it applies to. This matters because a language model on its own will quote brackets from its training snapshot, and tax rates change year to year, so a remembered figure is easy to state confidently and get wrong for anyone actually filing. Here the answer is grounded and dated, and when a rate cannot be verified Zeplik says so rather than guessing.
The lookup is free; you pay only the normal cost of the answer, shown before you send.
How it works
Ask about the bracket or rate
Ask in plain language, like 'what are the current federal income tax brackets?' or 'what rate applies to a single filer earning 90,000?'. Naming the tax and, where relevant, the filing situation is enough for Zeplik to run the lookup.
Zeplik reads the dated tax data
It reads curated tax data with a stated effective year, not the model's memory, and treats it as source material. The answer is anchored to the year the figures apply to, so a rate is never quietly presented as current when it is not.
Read the dated figure and apply it
The answer states the bracket or rate and the year it belongs to, so you can use it with confidence and know exactly which tax year it reflects, with a clear note when a figure cannot be verified.
Worked examples
Real prompts you can open in the composer with the text ready to review. Nothing sends on its own. Swap in your own details.
Prompt: What are the current federal income tax brackets for a single filer?
Zeplik reads the dated tax data and returns the brackets with the year they apply to, so you are not relying on a figure that may be a year or more out of date.
Open this in ZeplikPrompt: What marginal rate applies to 150,000 of taxable income, and what is the effective rate?
It grounds the calculation in the dated brackets and shows the year, so the marginal and effective figures are traceable rather than guessed.
Open this in ZeplikPrompt: Have the brackets changed from last year? What year does your data cover?
It states the effective year of its data plainly, so you know exactly how current the figures are instead of assuming.
Open this in ZeplikWhat it can and cannot do
The lookup is precise about what it can verify and honest about its edges. Here is the plain posture.
Look up income tax brackets and rates with the exact year they apply to, so the figure is never mislabeled as current.
Ask how a rate applies to an income level and Zeplik grounds the marginal and effective figures in the dated brackets.
The answer always names the tax year the data covers, so you know precisely how current the figures are.
If a rate cannot be confirmed in the curated data, Zeplik says so plainly instead of quoting a figure from memory.
It looks up rates; it is not a tax preparer and does not know your full situation. For filing decisions, consult a qualified tax professional.
Coverage focuses on the brackets and rates in its curated data. For a specific locality outside that, treat any figure as unverified and check the taxing authority.
Grounded, and honest by default
- It dates every figure. Each rate comes back with the tax year it applies to, so a bracket from a prior year is never presented as this year's.
- It will not guess a rate. When a figure cannot be verified in the curated data, Zeplik says so rather than quoting a plausible-looking number from memory.
- Source data cannot hijack the answer. The tax data is treated as untrusted content: Zeplik reads and reports it but never obeys instructions embedded inside it.
Frequently asked questions
- Why not just ask a chatbot for the current tax brackets?
- Because a language model answers from its training snapshot, and tax brackets are adjusted year to year, so a remembered figure is easy to state confidently and get wrong for the current year. This tool reads curated, dated tax data and always names the year the figures apply to.
- Which year does the data cover?
- Zeplik states the effective year of the figures in every answer, so you always know how current they are rather than having to assume.
- Can it tell me exactly what I will owe?
- It can look up the brackets and explain how a marginal and effective rate apply to an income level, but it is not a substitute for a tax preparer who knows your full situation, deductions, and credits. Zeplik is clear about this boundary.
- Does it cover state and local taxes?
- Coverage focuses on the brackets and rates in its curated data. For a specific state or municipality outside that, Zeplik treats any figure as unverified and points you to the taxing authority rather than guessing.
- Does the lookup cost credits?
- The tax-rate lookup itself is free. You pay only the normal model-token cost of the answer written around it, shown before you send, like any other message.
