From TD4 to e-Tax in about 10 minutes

No accounting degree required. Just your TD4 slip and a few minutes. TaxDash prepares everything and fills your e-Tax return automatically — you review and submit.

Step 01

Snap It or Upload It

Take a photo of your TD4 slip with your phone, or upload the file from your computer. TaxDash reads the numbers off it: your employer, your pay, and the income tax, NIS and Health Surcharge taken from it.

What you'll need: Your TD4 slip from your employer (one for each job), and a computer with Chrome to fill in e-Tax. Your phone is fine for taking the TD4 photo.

Step 02

Check the Numbers

Check the numbers TaxDash read from your TD4, and change anything that looks wrong. Then answer a few quick questions about your deductions, like pension payments, university fees abroad or a first home. TaxDash works out which ones apply and the most you can claim.

Step 03

Auto-Fill e-Tax and Submit

Log into etax.ird.gov.tt with your ttconnect ID and TaxDash fills every field for you — usually in 10–20 seconds. Review what's been filled, attach your supporting documents, and hit submit yourself. A one-time helper install (free, Chrome only) does the filling; no helper installed? A drag-to-bookmark link works instead, no install required.

Prefer to type it yourself? Your Tax Return Summary has every number matched to the official line numbers — auto-fill is optional, not required.

No e-Tax account? Auto-fill only works on the logged-in path. You can still use the non-logged-in service without a ttconnect ID — you'll print and sign a Declaration Form and drop it off at any IRD office.
