May 2026

“I used to find tax compliance confusing and honestly a bit stressful, especially with how often regulations seem to change. Working with C S Rushil & Co has made a huge difference. They simplified everything, explained what actually matters for my business, and handled things smoothly from GST filings to more detailed financial reviews. What I appreciate most is their proactive approach they don’t just react, they guide you ahead of time. It’s given me a lot more clarity and confidence in managing my business finances.”

Choosing a CA firm

What to look for in a CA firm

Whichever firm you choose, these are the checks worth making first. Where it applies, we have noted how C S Rushil & Co. measures up.

ICAI membership you can verify

Every practising chartered accountant holds an ICAI membership number, and every CA firm has a firm registration number (FRN). Ask for both and check them on icai.org before you sign up.

An itemised quote

A clear quote separates government fees (MCA filing fees, stamp duty, DSC charges) from the firm's professional fees, so you can see exactly what you are paying for.

A physical office you can visit

Being able to meet the team, drop off documents and sign papers in person makes registrations and notices easier to manage.

Our office is at Old Door No. AP-890, New No. 18, J-Block, 1st Street, 13th Main Rd, Anna Nagar, Chennai - 600040.

Clear response times

Ask every firm you are considering: how quickly will you reply to a query, and who will be my point of contact for filings and notices?

Online service across Tamil Nadu

Most GST, income tax and ROC work is filed online, so the firm should be able to work with you without repeated office visits.

We serve clients online across Tamil Nadu, and NRIs abroad, as well as in person in Chennai.
