How to Change a Tax Rate in Xero?
What Is the Quick Summary of Changing a Tax Rate in Xero?
You change a tax rate in Xero from the tax rates settings. Open Settings, go to Advanced settings (or Accounting > Advanced in some versions), and select Tax rates. You can edit a custom rate, or create a new rate with New Tax Rate, then apply it where you need it. Xero’s own default rates are locked, so a new percentage usually means a new rate.
- Where to go: Settings > Advanced settings > Tax rates.
- Main options: Edit a custom rate, add a new rate, or delete a rate you no longer use.
- After the change: Update defaults on accounts, contacts, items, and bank rules.
- Key caution: Past transactions do not change on their own, so review drafts and repeating items.
What Is Xero Accounting Software?
Xero Accounting Software is a cloud-based accounting platform that calculates tax on your invoices, bills, and other transactions using tax rates you manage in your settings. When a government changes a sales tax, VAT, or GST rate, or when you need a custom rate, update those settings to keep your records accurate. This guide shows you how to change a tax rate in Xero Accounting Software and how to apply the new rate across your accounts.
Correct tax rates protect your tax returns and your reports. Therefore, a few careful minutes in your settings can save hours of corrections later.
What Are Tax Rates in Xero and When Do You Need to Change One?
A tax rate in Xero tells the software how much tax to calculate on a transaction line. Xero includes standard rates for your region, such as a 20% VAT rate or a reduced rate. You can add custom rates for situations the defaults don’t cover.
When Should You Change a Tax Rate?
- A government changes a rate: For example, a GST or VAT increase takes effect.
- You need a special rate: A temporary reduced rate or a local tax applies to some sales.
- A rate name is unclear: You want a clearer display name for your team.
- A rate is obsolete: You want to remove a rate nobody should use any more.
Who Can Change Tax Rates?
Tax settings affect your whole organisation, so only users with the right permissions can edit them. If the Tax rates option does not appear, ask your Xero administrator to check your role.
How Does Xero Handle Rate Changes Announced by Governments?
Xero sometimes publishes updates for major changes. When Singapore raised its GST rate, Xero’s product blog explained that the new rate became available in advance and that the former rate was labelled with the year. Check Xero’s blog and Xero Central whenever your country announces a change.
How Do You Change or Add a Tax Rate in Xero Step by Step?
Xero treats custom rates and default rates differently. You can edit the display name of a custom rate, but a new percentage often requires a new rate. Menu names vary by region and version, so look under Settings or Accounting if your screen differs.
- Open your organisation name and select Settings.
- Click Advanced settings and select Tax rates.
- Review the list and the percentage column.
- Click an existing rate to edit it, or click New Tax Rate to add one.
- Enter a display name, the tax component name, and the percentage.
- Click Save.
- Update your defaults, as the next section explains.
How Do You Open the Tax Rates Screen?
This item is located in the organisation menu: select “Settings,” then “Advanced settings,” and finally “Tax Rates.”
How Do You Edit an Existing Tax Rate?
Click the rate name in the list and update the field you need. According to the Britebiz guide, you can edit the display names of custom rates or deactivate rates you no longer use, while the standard rates stay locked for compliance. One third-party guide says Xero applies an edited percentage to new transactions in the future and does not change old ones. Another says you cannot change the percentage of a rate that you already used in transactions. Because guides disagree, test the change on a draft first and confirm the behaviour on Xero Central.
How Do You Add a New Tax Rate?
Click New Tax Rate and enter a display name, such as “VAT 15.5%”. Add the tax component name and the percentage, and select a tax type if the form asks for one. Then click Save.
How Do You Delete or Deactivate a Rate?
Select the rate, then choose the option to delete it. Xero asks you to confirm. Remove only rates that you no longer need, and keep any rate that old transactions still use for reporting.
What Do the Fields on a Xero Tax Rate Mean?
Each tax rate has a few parts. Understanding them helps you build the rate correctly the first time.
| Field | What it means | Example |
|---|---|---|
| Display name | The label you see when you code a transaction | VAT 15.5% |
| Tax component name | The name of one part of the rate | VAT |
| Tax component percentage | The percentage of that part | 15.5 |
| Compound | Applies the tax on top of earlier components | Used for tax charged on tax |
| Tax type | The category that Xero uses for reporting | Sales or purchases tax |
| Effective rate | The total of all components | 15.5% |
What Are Tax Components?
A tax component is a percentage that makes up an overall rate. Xero adds the components together and applies the total to the line amount. For instance, a combined sales tax might include a state component and a city component.
What Does a Compound Component Do?
A compound component applies on top of the previous components. Use it only when your tax law charges tax on the tax. Otherwise, leave the option off, and ask your accountant if you are unsure.
Which Account Types Can Use a Rate?
A rate can apply to revenue, expense, asset, liability, or equity accounts, depending on how it’s set up. If a rate does not appear in a dropdown, check whether it applies to that account type.
How Do You Apply the New Tax Rate Across Xero?
Creating or editing the rate is only half the job. Xero fills in tax rates from several default settings, so each one needs a review. Xero’s Singapore GST update explained that defaults can sit on contacts, inventory items, and accounts in the chart of accounts, and that transactions using them keep the old rate until you update them.
| Where the default lives | How to update it |
|---|---|
| Chart of accounts | Open Accounting > Chart of Accounts, click the account, and choose the new default tax rate |
| Contacts | Edit each customer or supplier and set the new default tax rate |
| Products and services | Edit each item and update the sales and purchase tax rates |
| Bank rules | Amend each rule that sets a tax rate |
| Repeating invoices and bills | Edit each template that will generate documents after the change |
| Draft documents | Open each draft and select the new rate on the lines |
How Do You Update the Chart of Accounts Defaults?
Go to Accounting > Chart of Accounts and click an account such as Sales. Use the Tax Rate dropdown to pick the rate you use most often for that account. Xero then fills in this rate whenever you choose the account on a transaction line, as the Britebiz guide describes. Review every revenue and expense account, because one missed account keeps applying the old rate.
How Do You Update Contacts and Items?
Open each affected contact or inventory item and change the default tax rate. When a government changes a rate, Xero has offered a button on the chart of accounts page for some regions to update defaults in bulk. That button appears only for certain roles and only when the accounts use Xero’s default rates, so check whether your region offers it.
How Do You Fix Bank Rules and Repeating Items?
Bank rules and repeating invoices or bills do not follow your new rate automatically. Edit each one by hand, as the Fiscal Harmony guide recommends. Otherwise, Xero keeps generating documents with the old rate after the change date.
What Happens to Existing Transactions When You Change a Tax Rate in Xero?
Past transactions keep the rate they used. According to the Fiscal Harmony guide, you cannot directly change the percentage of an existing rate that transactions already use, so you create a new rate and apply it going forward. For unpaid transactions, you can edit the document and select the new rate on the line items.
How Do You Change the Tax Rate on an Existing Invoice or Bill?
- Open the transaction from the Invoices or Bills page.
- Check whether the Amounts are set to tax-exclusive or tax-inclusive.
- Select the new tax rate in the Tax rate dropdown on each line.
- Review the new total.
- Save or approve the document.
If the document already has a payment, you may need to remove the payment first. Take a note of the payment details before you do so so you can record it again.
What Role Do Lock Dates Play?
A lock date prevents changes to transactions before a date you set. If Xero blocks your edit, the transaction probably falls in a locked period. Ask an adviser or administrator before you change the lock date, because tax returns for that period may already exist.
How Do You Check Your Tax Reports After the Change?
Open the Tax Summary report in the Reports section and filter by date range. Review the figures by tax rate to confirm that each rate appears on the right transactions. This check helps you catch errors before you file a return, as the Britebiz guide suggests.
What Are the Most Common Tax Rate Mistakes in Xero and How Do You Avoid Them?
Tax errors often come from forgotten defaults rather than from the rate itself. The table below lists frequent mistakes and fixes.
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Forgetting to update account defaults | Xero keeps applying the old rate | Review every account in the chart after a change |
| Skipping contacts and items | New invoices still use the old rate | Update default rates on contacts and items |
| Ignoring bank rules | Reconciled transactions use the old rate | Edit each rule that sets a tax rate |
| Leaving repeating templates alone | Future documents carry the old rate | Edit repeating invoices and bills |
| Overwriting a rate that old data uses | History becomes confusing | Create a new rate for a new percentage |
| Deleting a rate too early | Old transactions lose clarity in reports | Keep rates that past periods use |
| Mixing tax exclusive and inclusive | Totals differ from expectations | Check the Amounts are setting on each document |
Why Does Xero Still Use the Old Rate on New Accounts?
Users on Xero Product Ideas report that a new account in the chart of accounts can start with an old default rate. Therefore, check the tax rate field every time you create an account. This habit prevents errors that are hard to trace later.
How Do You Spot Wrong Rates Quickly?
Run the Tax Summary report for a short period after the change. Compare the rates shown with what you expect, and open any transaction that looks wrong.
What Best Practices Help You Manage Tax Rates in Xero?
A short routine keeps your tax setup reliable, especially when rates change often.
Which Habits Keep Tax Rates Accurate?
- Name rates clearly: Include the percentage and, if useful, the year, as in “VAT 15.5% (2026)”.
- Create a new rate for a new percentage: Keep history intact for past periods.
- Update all default locations: Accounts, contacts, items, bank rules, and repeating templates.
- Test on a draft: Check the calculation before you approve real documents.
- Review the Tax Summary report: Do this before each return.
- Document the change date: Record when the new rate takes effect.
When Should You Ask an Accountant?
Ask for advice when you are unsure which rate applies, when a change falls inside a period you already reported, or when compound or multi-component rates are involved. Tax rules differ by country, and Xero calculates what you configure, so a professional can confirm that your setup matches the law.
Do You Need to Repeat the Process for Each Organisation?
Yes. Tax settings belong to each Xero organisation, so repeat the review in every organisation you manage. Xero’s Singapore GST guidance made the same point for businesses with several organisations.
What Are the Key Takeaways From Changing a Tax Rate in Xero?
Changing a tax rate in Xero follows a simple path. Open the tax rates settings, edit a custom rate or create a new one, and then apply the new rate wherever Xero uses defaults. Xero Accounting Software keeps past transactions on their original rates, so you must update accounts, contacts, items, bank rules, and repeating templates yourself.
To stay safe, create a new rate when the percentage changes, test it on a draft, and review the Tax Summary report before you file. In addition, confirm any unclear points with Xero Central or your accountant. As a result, Xero Accounting Software keeps your tax calculations consistent and your reports trustworthy.
