Key takeaways
- A tracker earns its keep on events. Certificates arriving, companies dissolving, rounds repricing. Only a tracker connected to the register notices those without you typing them in.
- Two of the six options cost nothing to start. Haatch's app and a spreadsheet. The cost is your time, and whatever you fail to notice.
- Ask what happens on a dissolution. Loss relief has a deadline. If the tracker cannot tell you a company was struck off, the deadline runs anyway.

Let AI do the checking, then keep watching
- Run due diligence on any UK company. Nine AI agents read the registers, the courts and the founders' histories. Every figure cited.
- Add a holding to monitoring. Every filing on it, the week it lands, with what it means for your stake.
- Upload your EIS and SEIS spreadsheet. Export it as CSV. Tero maps the columns, starts every clock and chases the certificates.

EIS and SEIS relief is generous and administratively unforgiving. Each holding carries a certificate you have to obtain and a claim window that closes. It carries a three-year clock that claws the relief back and a two-year clock for inheritance tax. And it carries a loss-relief deadline that runs whether or not you noticed the company had died. An EIS tracker is whatever keeps those straight. Six ways UK angels do it, scored on the same tests. Tero's tracker is ours and gets no special treatment.
| Rank | Tool | Score | Best for | Price |
|---|---|---|---|---|
| 1 | Teroours | 9.2/10 | Direct holdings where your name is on the register | Included in plans from £10 a month; founding members free |
| 2 | EIS Traaker by Haatch | 5.8/10 | A tidy manual log of a small portfolio | Free; iPhone, Android and web |
| 3 | SeedLegals for Investors | 5.0/10 | Portfolios where the companies run on SeedLegals | Investor membership £499 a year plus VAT |
| 4 | AngelTrack | 5.0/10 | Organising documents and updates across a portfolio | 90-day trial, then £25 a month for up to 25 investments |
| 5 | A spreadsheet | 5.0/10 | Starting out, or nominee-heavy portfolios | Free |
| 6 | Your accountant | 3.3/10 | The return itself | Their fee |
How the score is built: 6 tests, each scored 0, 1 or 2: holds the six records; computes the clocks; notices events without typing; reads the register; produces the accountant pack; priced for an individual. Points out of 12, shown out of ten. Tero is ours and sits the same tests. It loses a point on price: the tracker sits in the paid plans. Prices as at September 2026.

Teroours
Relief tracking that reads the register
9.2/10
11 of 12 points
Add a company by its registered name and Tero reads your shares, class and percentage from the confirmation statement. Amount and date start every clock: claim-by, three-year, two-year, capital-gains windows. It tracks certificate stages and flags a certificate that has not arrived once the shares are issued. Because it watches the register, a strike-off or a new priced round reaches you the week the company files it. That is the week loss relief becomes claimable.

5.0/10

AngelTrack
Portfolio record with the founder in the loop
5.0/10
6 of 12 points
A UK app built by two angels: rounds and investments logged, documents and tax forms stored against each holding, confidential updates and event scheduling with founders and co-investors. A good record with the founder attached. It knows what you type in. It does not know what the company filed.

A spreadsheet
Fourteen columns and discipline
5.0/10
6 of 12 points
Company and number, scheme, advance assurance, investment and issue dates, amount, shares, certificate status, unique investment reference, claim status, and three computed dates. Free and flexible. It fails where every spreadsheet fails: events happen off the sheet, and a struck-off company appears in the register and nowhere else.

Your accountant
Claims what you give them
3.3/10
4 of 12 points
An accountant claims accurately and on time from the records you hand over. They cannot chase the certificate the founder never issued. They will not see the strike-off notice in the filing history. Nobody warns you in month thirty that a sale would claw the relief back. Paired with a tracker, this works. Alone, it does not.

Six tests for an EIS tracker
Nominee holdings
Crowdcube, Seedrs and most EIS funds hold the shares through a nominee. Your name never reaches the register. The company's confirmation statement shows the nominee, so no EIS tracker can read your holding from it. Every tool on this list, Tero included, needs you to type these in. The rest still works. The clocks run from the dates you enter, the certificate stages still get chased, and a strike-off still shows up because the tracker watches the company itself. The nominee sends the certificate, sometimes months after the platform said it would. Log the date you asked.
What happens on a dissolution
A dissolved company writes to nobody. The strike-off notice appears in the filing history and in The Gazette, and that is all. From that date the loss-relief clock runs. An EIS tracker that reads the register sends you the notice the week it lands. One that does not waits for you to find out, and angels usually find out at the next spring-clean. See how loss relief works.
Moving off a spreadsheet
Most angels arrive at an EIS tracker with a spreadsheet already in hand. Keep it for one tax year. Enter each holding in the tracker with the same figures, then compare the computed dates with your own. Where they differ, the difference is usually the share-issue date. The sheet often carries the day the money left your account, and the clock runs from the date on the certificate. Once the two agree, retire the sheet and let the register do the noticing.
Choosing
If your holdings are direct and your name is on the register, a tracker that reads the register removes most of the typing and all of the not-noticing. If you invest through nominees or funds, choose between a good spreadsheet and an app that stays tidy. The question to keep asking is the same: how would I find out if this company died? Information, not tax advice. Relief depends on your circumstances and on the company keeping its qualifying status.

Questions this guide answers
- What should an EIS tracker actually track?
- Per holding: the investment and share-issue dates, the amount, the scheme, the shares and share class. Then the EIS3 or SEIS3 certificate with its unique investment reference, and whether you have claimed the relief. Then three computed dates: claim-by, three-year clawback and two-year inheritance tax.
- Is there a free EIS tracker?
- Two options cost nothing: Haatch's EIS Traaker and a well-built spreadsheet. Tero's tracker comes with the paid plans, from £10 a month. The paid difference is whether the tracker reads the register for you, so dissolutions, allotments and ownership arrive without typing.
- Can my accountant track my EIS investments?
- They can claim what you give them. Most accountants work from your records at year end, so the certificate chasing, the clocks and the dissolutions still fall to you. A tracker is the record you hand them.
- Why do spreadsheets fail for EIS portfolios?
- Events happen off the sheet. Certificates arrive or do not, companies raise again at new prices, and companies dissolve, and a dissolved startup does not write to its shareholders. The sheet only knows what you remembered to type.
