Heed vs spreadsheets and calendar reminders
Reviewed 17 October 2026
The short answer
A spreadsheet holds what you put in it: the days you remember to log, the rates you looked up once, the deadlines you entered. Heed keeps those current for you. It counts days against each country's rule, keeps rates with their official source and date, and tells you when something you rely on changes.

| Tax rates | As of the day you looked | With their official source and the date checked |
| Rule changes | Only if you hear about them | Alerts matched to your situation |
| Deadlines | Reminders you set yourself | Due dates from the changes that affect you |
| Sharing with an adviser | Send the file | Briefs and PDF exports on Pro |

Which one, when.
When spreadsheets is enough
- Your life sits in one country and rarely changes.
- You enjoy keeping the model yourself and check the sources often.
How they work together
Keep your own model if you like it. Let Heed watch the inputs: the day count, the rates and the rules your formulas depend on.
03Questions
What people ask.
Straight answers. Heed is intelligence, not advice.
Only what the tools need: the countries, income types and assets you choose to add for matching, and dates for the day count. Heed never asks for passport or document numbers.
Each rate links to the page it was checked against, says whether that page is official, and shows the date it was last checked.
