Year-Round Tax Compliance for Indian Freelancers: No March Rush

March 10pm. CA Send FY invoices, GST split, advance proof. Drive INV-12 final FINAL2.pdf 23 files, GOS/25-26/014 missing, taxType CGST? IGST? forgotten, advance ₹30k not linked. You Give me 2 days — ₹5k CA extra + penalty risk.

Year-round compliance is invoices typed correctly once so March is export, not reconstruct.

Why Indian Freelancers Rush in March

Three gaps compound monthly:

• GST split guessed. taxType cgst_sgst|igst src/app/api/invoices/route.ts:124 decides 9+9 vs 18. Sheets GST 18% doesn't split; re-calc 40 invoices Mar 28 → err ₹18k → GSTR-1 mismatch.
• Invoices untethered. invoices invoiceNumber unique src/lib/db/schema.ts:67 + issueDate src/lib/db/schema.ts:71 should be GOS/25-26/014. Drive FINAL2 breaks trail; missing dueDate src/lib/db/schema.ts:72 → cron sent→overdue src/app/api/cron/daily/route.ts:46 never flipped.
• Advances invisible. advance ₹30k as UPI not transactions category:Project Advance src/app/api/transactions/route.ts:57 → syncProjectAdvance src/app/api/transactions/route.ts:21 never updated projects advance src/lib/db/schema.ts:36. CA sees ₹5L vs bank ₹5.3L — gap, not proof.

Scattered files make compliance = March reconstruction. Linked graph makes compliance = daily correctness.

The Year-Round Linked Compliance Graph

RunoSO tenant_${id} src/lib/db/tenant.ts:47 stores tax correctness at write time, not March:

invoices(id, invoiceNumber unique src/lib/db/schema.ts:67, issueDate timestamp src/lib/db/schema.ts:71, dueDate, amount numeric(12,2) src/lib/db/schema.ts:69, currency INR, items jsonb src/lib/db/schema.ts:74, discount numeric src/lib/db/schema.ts:75, taxRate numeric(5,2) src/lib/db/schema.ts:76, taxType varchar(50) src/lib/db/schema.ts:77, recurringInterval varchar(20) src/lib/db/schema.ts:80, recurringNextDate timestamp src/lib/db/schema.ts:81, clientId fk, projectId fk)
transactions(type income|expense src/lib/db/schema.ts:87, amount numeric, category varchar(100), currency INR, date timestamp src/lib/db/schema.ts:96, clientId, projectId, invoiceId)
cron daily 30 3 * * * vercel.json:4 → flips sent→overdue lt(dueDate, now) src/app/api/cron/daily/route.ts:49 + advances recurring via nextRecurringDate() src/lib/utils/recurring.ts:5

What auto correctness gives:

1. GST at source. POST /api/invoices src/app/api/invoices/route.ts:84 validates taxRate 0..100 + taxType none|cgst_sgst|igst. Server tax = taxable*rate/100 src/app/api/invoices/route.ts:121 → computedTotal src/app/api/invoices/route.ts:127 toFixed(2) — no 9+9 vs 18 error.
2. Invoice trail gap-free. invoiceNumber GOS/25-26/014 status draft|sent|paid|overdue src/lib/db/schema.ts:58 + items jsonb — items + taxRate + taxType is GSTR taxable + tax. GET /api/invoices page+pageSize src/app/api/invoices/route.ts:43 paginates FY audit.
3. Advance & paid sync. status paid → auto transactions Invoice Payment src/app/api/invoices/route.ts:154 → syncInvoicePaidStatus src/app/api/transactions/route.ts:44 flips sent→paid else cron sent→overdue. CA sees advance 30k + invoice 014 paid = ₹90k linked.
4. Retainers compliant yearly. recurringInterval monthly|quarterly|yearly src/lib/utils/recurring.ts:5 clones preserving dueGapMs src/app/api/cron/daily/route.ts:92 — Apr 2025→2026 sequence unbroken.

Month-by-Month Calm, Not March Rush

30 min/mo = 6 hours/yr. March reconstruction 2 days × 6h = 12h + ₹5k CA extra. Year-round wins by double.

Excel vs QuickBooks vs FreshBooks vs RunoSO — India Compliance

Excel is free but FY-gap risky; QuickBooks/FreshBooks auto-compute US tax not Indian cgst_sgst|igst. RunoSO auto cgst_sgst|igst + linked advance + cron.

Three Mistakes That Trigger Notices

Mixing inter vs intra without taxType. Mumbai cgst_sgst 9+9 vs Delhi igst 18 — set correct taxType at POST or credits disallowed.

Invoicing late. Work Mar 28 invoice Apr 02 slips FY. Create issueDate = work done date src/lib/db/schema.ts:71.

Not linking invoiceId. UPI ₹59k without invoiceId src/lib/db/schema.ts:98 → CA can't tie TDS → always POST invoiceId when Invoice Payment.

RunoSO makes every invoice GST-correct at creation — cgst_sgst|igst split, amount server-computed, advance linked, overdue auto — so March is export, not emergency.

FAQ

Do I need GST if under ₹20L? Under threshold you may be exempt, but many clients need GST-compliant invoice for ITC — taxType none with taxRate 0 src/app/api/invoices/route.ts:30 works until you cross. Track sum amount where taxType != none to know when you cross — year-round view beats March surprise.

How does RunoSO handle CGST vs IGST? At POST /api/invoices choose taxType:cgst_sgst intra-state 9+9 or igst inter-state 18 src/app/api/invoices/route.ts:124. Server tax = taxable*rate/100 src/app/api/invoices/route.ts:121 computed once — no Sheet =B2*18% vs =B2*9% error.

Can I export FY data for my CA? Yes — GET /api/invoices + GET /api/transactions?startDate=2025-04-01&endDate=2026-03-31 src/app/api/transactions/route.ts:88 paginated pageSize 20 src/app/api/invoices/route.ts:44. Solo data_export true src/lib/plans/limits.ts:58 enables bulk; free 5/mo src/lib/plans/limits.ts:28 tracks count via checkPlanLimit src/app/api/invoices/route.ts:101.
