VAT, GST and tax compliance services, jurisdiction by jurisdiction.

VAT, GST and tax compliance services cover registration, return preparation, filing and the record keeping behind them, in every country where you carry an obligation. For Accountaire that means UK VAT under Making Tax Digital, US state sales tax, UAE FTA VAT and Corporate Tax, Canadian GST/HST and Australian BAS.

Tax compliance is where shortcuts get punished. Late filings carry penalties; wrong filings carry penalties plus interest plus the cost of resubmission. The rules change every year, often quietly, and the consequences of getting it wrong land directly on your business, not your accountant.

We treat tax as a discipline, not an afterthought. Returns are prepared from clean books, reviewed against current-year rates and rules, and filed via the agent portal that your regulator expects. We register as your tax agent with HMRC, the IRS, the FTA, the CRA and the ATO, so submissions go through formally on your behalf with full audit trail.

Our team holds the qualifications and registrations your tax authority actually recognises: ACCA-qualified accountants, HMRC Agent authorisation for UK clients, FTA Tax Agent status for UAE VAT, IRS e-File provider registration for US clients. When we file, it's on the authorised channel.

We don't treat compliance as a transactional service. Tax planning, year-end optimisation and regulatory change-watching are part of the engagement, so you don't end up paying more than you should, or get caught off-guard by a rate change you didn't see coming.

Registration thresholds are the first thing to get wrong, because they creep up on you in a rolling window rather than at a year end:

• United Kingdom. VAT registration is compulsory once taxable turnover passes £90,000 in any rolling 12 months, or if you expect to pass it in the next 30 days alone. HMRC sets out the test in full. Returns and payment are due one calendar month and seven days after the period end, filed through Making Tax Digital software. See UK MTD VAT compliance.
• United States. There is no federal sales tax. Since South Dakota v. Wayfair in 2018, states set their own economic nexus tests, commonly $100,000 of sales into the state in a year, with some still using a 200-transaction limb. Registration is per state. See US sales tax compliance and our guide to US sales tax nexus.
• United Arab Emirates. VAT registration is mandatory above AED 375,000 of taxable supplies and voluntary above AED 187,500, at a 5 percent standard rate, filed through EmaraTax. Corporate Tax is 9 percent on taxable income above AED 375,000. Rules are published by the Federal Tax Authority. See UAE VAT and Corporate Tax.
• Canada. You stop being a small supplier once worldwide taxable revenue passes CAD 30,000 across four consecutive calendar quarters, after which GST/HST registration with the Canada Revenue Agency is required. See Canadian GST/HST filing.
• Australia. GST registration is required at AUD 75,000 of turnover, and quarterly BAS lodgement with the Australian Taxation Office falls 28 days after the quarter end, with the December quarter extended to 28 February. See Australian BAS and GST.

The failure pattern is nearly always the same, and it is rarely the return itself. A business trades past a threshold two or three months before anyone notices, so the first correct return has to carry back tax that was never charged to the customer. That gap comes out of margin. On a UK business that crossed £90,000 four months late with a 60 percent gross margin, the unbilled VAT on those four months is real money the customer will not now pay. Watching the rolling window is part of the monthly close, not an annual review.

The second pattern is a filing that is technically on time and arithmetically wrong, because the ledger underneath it was not reconciled. A VAT return prepared from an unreconciled control account will disagree with the accounts at year end, and the correction is an error notification rather than a quiet adjustment. Clean cloud bookkeeping is what makes the return defensible, and the two services are normally bought together. If the returns are already late, the catch-up bookkeeping service handles the back filings first.

For the UK detail, including digital links and what MTD actually requires of your records, read our Making Tax Digital for VAT guide. For the UAE calendar, the UAE VAT and Corporate Tax compliance calendar sets out every date in the year. Personal returns for UK directors sit on the Self-Assessment filing service rather than here. Country-specific walkthroughs sit alongside this page: the GST/HST filing guide for Canada and the BAS lodgement guide for Australia cover the two regimes most often missed, and our accounting and tax glossary defines the terms used across all five markets. Tax filing is one entry in our list of accounting services we run, which lists everything we run alongside it.
